00:04:07.212 --> 00:04:07.821 >> It makes sense. 00:04:07.821 --> 00:04:09.780 >> Yes it does make sense. 00:04:09.780 --> 00:04:12.770 So let's jump in the first thing, 00:04:12.770 --> 00:04:18.160 first very thing we are going to do is import our cardboard SDK. 00:04:18.160 --> 00:04:22.625 And the way we're going to do this, is under assets, 00:04:22.625 --> 00:04:25.610 Import Package, Custom Package. 00:04:25.610 --> 00:04:28.540 >> And this is gonna get that package that you said 00:04:28.540 --> 00:04:30.710 we needed to have downloaded ahead of time. 00:04:30.710 --> 00:04:33.190 >> Right. This is the cardboard SDK. 00:04:33.190 --> 00:04:35.650 I know I saved mine in My Downloads, 00:04:35.650 --> 00:04:37.880 it's the only thing that it's in My Download, other than folder. 00:04:41.200 --> 00:04:46.180 And it's going to import all of these assets straight for me. 00:04:47.660 --> 00:04:49.450 It's going to ask which ones you want. 00:04:49.450 --> 00:04:50.540 I am importing them all. 00:04:55.380 --> 00:04:58.160 And what you're going to see after they are done importing 00:04:58.160 --> 00:05:02.435 is two folders are going to pop up named cardboard and plugin. 00:05:02.435 --> 00:05:09.300 Underneath assets we see cardboard and plugins. 00:05:12.060 --> 00:05:14.870 So under assets we are actually going to make a new folder 00:05:14.870 --> 00:05:18.040 next to these two folders called cardboard and 00:05:18.040 --> 00:05:20.840 plugins named our assets. 00:05:20.840 --> 00:05:23.180 So the way I'm doing this, I just right-clicked and 00:05:23.180 --> 00:05:26.880 then create folder there's also another way that you can bring 00:05:26.880 --> 00:05:28.115 up this menu. 00:05:28.115 --> 00:05:31.410 under the project tab there's a little thing right below it that 00:05:31.410 --> 00:05:34.190 says create and then you can click on folder. 00:05:34.190 --> 00:05:37.540 >> And this is just a peek into your asset folder 00:05:37.540 --> 00:05:38.450 of your project. 00:05:38.450 --> 00:05:42.221 So you know if you made a folder in Explorer it would show up 00:05:42.221 --> 00:05:43.172 here as well. 00:05:43.172 --> 00:05:46.183 Exactly, so our assets, we made this folder 00:05:46.183 --> 00:05:50.160 to distinguish what we've imported already from Google. 00:05:50.160 --> 00:05:52.270 These are the ones that are pre-done for us. 00:05:52.270 --> 00:05:54.660 And these are gonna be the ones we write ourselves, write and 00:05:54.660 --> 00:05:55.720 create ourselves. 00:05:55.720 --> 00:05:57.390 >> And again, that's not required for the code. 00:05:57.390 --> 00:06:00.550 But that's just what makes things cleaner and easier for 00:06:00.550 --> 00:06:02.180 the sake of our demo. 00:06:02.180 --> 00:06:03.060 >> Exactly. 00:06:03.060 --> 00:06:05.070 In our assets, 00:06:05.070 --> 00:06:08.040 we are going to create another new folder named scenes. 00:06:08.040 --> 00:06:10.940 And guess what we're going to do in here? 00:06:10.940 --> 00:06:11.580 >> Put our scenes? 00:06:11.580 --> 00:06:12.820 >> We're gonna save. 00:06:12.820 --> 00:06:16.230 First thing we should do is save our scene. 00:06:16.230 --> 00:06:19.730 So right here, the File Explorer just kind of pops up our assets. 00:06:19.730 --> 00:06:21.440 We can click on our assets and 00:06:21.440 --> 00:06:25.220 our scenes folder and save our playing field. 00:06:25.220 --> 00:06:25.720 Whoops. 00:06:26.720 --> 00:06:27.500 >> And just to clarify, 00:06:27.500 --> 00:06:30.230 what you're saving is this initial scene that has 00:06:30.230 --> 00:06:31.200 the directional light and 00:06:31.200 --> 00:06:34.110 the camera that was created when you made a new project and 00:06:34.110 --> 00:06:36.610 even though it created that initial scene it didn't 00:06:36.610 --> 00:06:39.630 save it for us in case we decided we didn't want it. 00:06:39.630 --> 00:06:40.920 But we've decided, yes, 00:06:40.920 --> 00:06:43.750 that's how we wanna start our first scene. 00:06:43.750 --> 00:06:44.652 Exactly and 00:06:44.652 --> 00:06:49.261 this will be really good just in case Unity crashes on us and. 00:06:49.261 --> 00:06:50.540 >> Yes, always save. 00:06:50.540 --> 00:06:53.380 >> Always save your stuff, it's the first thing we do so 00:06:53.380 --> 00:06:54.710 we can keep saving throughout. 00:06:54.710 --> 00:06:56.130 >> Early and often. 00:06:56.130 --> 00:06:57.520 >> Early and often. 00:06:57.520 --> 00:07:00.374 >> So, the first thing now that we've got everything kind of 00:07:00.374 --> 00:07:02.450 just peripherally set up. 00:07:02.450 --> 00:07:04.540 >> Is actually start to create our playing field. 00:07:05.910 --> 00:07:08.340 So the first thing we're going to do is add our ground. 00:07:08.340 --> 00:07:11.460 And our ground is going to be a 3D plane. 00:07:11.460 --> 00:07:13.120 So I'm going to make a 3D plane. 00:07:14.250 --> 00:07:17.470 So I brought this menu up by right clicking in the Hierarchy, 00:07:17.470 --> 00:07:20.820 choosing 3D object, and then I can choose plane. 00:07:20.820 --> 00:07:24.260 I can also bring this menu up by going to the role create 00:07:24.260 --> 00:07:26.230 button that's underneath Hierarchy. 00:07:26.230 --> 00:07:28.650 Choosing 3D object and plane. 00:07:28.650 --> 00:07:31.940 And one other way I can do it is under game object 00:07:31.940 --> 00:07:34.270 up here at the top. 00:07:34.270 --> 00:07:36.020 3D object, plane. 00:07:37.020 --> 00:07:38.990 These are all ways that you can bring up the same menu. 00:07:40.210 --> 00:07:43.430 I find that right clicking to be fastest and easiest. 00:07:43.430 --> 00:07:46.350 I'm going to rename plane to be ground because this is our 00:07:46.350 --> 00:07:48.480 ground and the last thing I'm going to do for 00:07:48.480 --> 00:07:52.820 it is set scale up over here in the inspector. 00:07:52.820 --> 00:07:55.300 We see that this thing is called transform, 00:07:55.300 --> 00:07:57.120 this holds three properties for us. 00:07:57.120 --> 00:07:59.254 Our position in space, our rotation, 00:07:59.254 --> 00:08:02.754 current rotation of this object, and scale, so the size of it. 00:08:02.754 --> 00:08:06.009 I'm gonna change the scale so that x is 2 and z is 2. 00:08:06.009 --> 00:08:07.129 You can just kind of. 00:08:07.129 --> 00:08:10.333 >> It's important to note too that, of every game 00:08:10.333 --> 00:08:14.140 object in Unity They all have the component transform. 00:08:14.140 --> 00:08:16.340 It's the one thing that they have in common, it's the one 00:08:16.340 --> 00:08:19.770 component that you can guarantee is on every game object. 00:08:19.770 --> 00:08:23.190 >> Exactly. And you can just see by changing 00:08:23.190 --> 00:08:25.290 the scale of it, it just kinda popped it bigger. 00:08:26.410 --> 00:08:29.080 That's gonna be really good cuz this is our playing field. 00:08:29.080 --> 00:08:31.010 And you can see that I'm changing perspective 00:08:31.010 --> 00:08:33.660 around in the scene, the way I'm doing this. 00:08:33.660 --> 00:08:35.220 I hold Alt and 00:08:35.220 --> 00:08:38.180 this kind of changes it to a little eyeball over here and 00:08:38.180 --> 00:08:41.400 then click and drag to kinda change perspective. 00:08:41.400 --> 00:08:43.800 You can also do this by right-click and 00:08:43.800 --> 00:08:47.610 hold and drag, but I like holding Alt better. 00:08:47.610 --> 00:08:48.410 >> Makes sense. 00:08:48.410 --> 00:08:51.070 I definitely would advise doing any Unity development with 00:08:51.070 --> 00:08:52.190 a three-button mouse. 00:08:52.190 --> 00:08:55.210 It will make your life a lot, lot easier. 00:08:55.210 --> 00:08:57.750 >> Especially since you can zoom in by scrolling. 00:08:57.750 --> 00:08:59.310 >> Yes that is also very handy. 00:09:00.480 --> 00:09:03.200 >> Right, so now that we've made our ground we should 00:09:03.200 --> 00:09:05.570 probably make the borders of our arena. 00:09:05.570 --> 00:09:08.560 So we're going to do this by creating a 3D cube, so I'm going 00:09:08.560 --> 00:09:12.850 to bring up that 3D objects menu again and choose cube. 00:09:12.850 --> 00:09:13.660 Straight off the bat, 00:09:13.660 --> 00:09:16.380 I'm going to rename it to something that is not cube. 00:09:16.380 --> 00:09:21.710 Probably left order is very obvious and straight forward. 00:09:21.710 --> 00:09:24.490 And right now, you can see, it just popped up but 00:09:24.490 --> 00:09:28.260 I don't see where it is, so I'm just going to set it to zero, 00:09:28.260 --> 00:09:32.860 zero, zero and right there, I can see it now, in my scene. 00:09:32.860 --> 00:09:36.040 Any time I lose something I find it helpful to recenter it by 00:09:36.040 --> 00:09:38.020 changing its origin back to 000. 00:09:38.020 --> 00:09:41.160 >> But it's still a little tiny dot in the center of that plane, 00:09:41.160 --> 00:09:43.650 it doesn't quite look like a wall yet. 00:09:43.650 --> 00:09:44.165 >> Yeah. So 00:09:44.165 --> 00:09:49.365 we probably want to pop it up, that's a little bit too far, 00:09:49.365 --> 00:09:54.565 but you know what, I think we can actually stretch it out and 00:09:54.565 --> 00:10:00.194 make it border looking by maybe changing its scale a little bit. 00:10:00.194 --> 00:10:02.935 Something along the lines of this. 00:10:02.935 --> 00:10:06.870 See, that looks like a wall. 00:10:06.870 --> 00:10:11.850 So by putting in the values of scale x, as x being 0.5, 00:10:11.850 --> 00:10:16.526 y being 2, and z being 20.5 you 00:10:16.526 --> 00:10:20.420 can already tell that it just kind of looks like a wall. 00:10:20.420 --> 00:10:25.040 And I can pop it into place by changing the x position 00:10:26.460 --> 00:10:27.690 to negative 10. 00:10:27.690 --> 00:10:33.865 Although it just popped over there on our left side. 00:10:33.865 --> 00:10:35.630 >> Makes sense. 00:10:35.630 --> 00:10:38.500 >> So I am going to duplicate that. 00:10:38.500 --> 00:10:43.157 That was Ctrl+D or you can just kind of right-click Duplicate. 00:10:43.157 --> 00:10:47.459 Rename this to be Right Border and 00:10:47.459 --> 00:10:51.460 change its x position to 10. 00:10:51.460 --> 00:10:53.280 >> Positive 10 as opposed to negative 10 and 00:10:53.280 --> 00:10:55.060 it's on the opposite side. 00:10:55.060 --> 00:10:58.540 >> Yeah, automatically like that, that was convenient. 00:10:58.540 --> 00:11:02.040 I'm going to duplicate it one more time near border. 00:11:04.950 --> 00:11:06.000 Let's change this back to zero. 00:11:06.000 --> 00:11:08.032 So now let's pop back in the middle. Let's- 00:11:08.032 --> 00:11:09.215 >> But now we gotta change that 00:11:09.215 --> 00:11:09.940 scale, right? 00:11:09.940 --> 00:11:11.866 So it's stretched the other way. 00:11:11.866 --> 00:11:12.449 >> Exactly. 00:11:12.449 --> 00:11:17.907 So we just switch these two values 20.5, 0.5. 00:11:17.907 --> 00:11:19.260 There we go. 00:11:19.260 --> 00:11:23.780 We can change its position negative 10. 00:11:23.780 --> 00:11:25.890 Right here we change the z instead of the x. 00:11:27.110 --> 00:11:29.730 Then I bet you guys can guess our far border 00:11:31.640 --> 00:11:36.000 is going to change to positive 10. 00:11:36.000 --> 00:11:38.540 And right now in our scene view we can see that we have 00:11:38.540 --> 00:11:40.500 a beautiful-looking arena. 00:11:40.500 --> 00:11:42.730 >> Awesome, that looks great and safe. 00:11:42.730 --> 00:11:44.117 >> Yeah. 00:11:44.117 --> 00:11:46.220 They won't fall out of this arena. 00:11:46.220 --> 00:11:49.320 But if you can see it in our hierarchy over here on the left, 00:11:49.320 --> 00:11:50.910 this will get a little cluttered, 00:11:50.910 --> 00:11:53.670 it would be really nice if we could just kind of like group 00:11:53.670 --> 00:11:58.020 all of our borders in one place, so I'm going to do exactly that. 00:11:58.020 --> 00:12:00.170 I'm going to create an Empty Game Object, 00:12:00.170 --> 00:12:03.060 it's right above 3D Object, Create Empty. 00:12:04.300 --> 00:12:07.463 I'm going to name this Object Borders, I'm going to make 00:12:07.463 --> 00:12:10.303 sure that its position is just kind of set to 0, 0, 00:12:10.303 --> 00:12:13.032 0, because this thing isn't really anything. 00:12:13.032 --> 00:12:16.009 And I'm going to group all of these borders together and 00:12:16.009 --> 00:12:18.730 drag them on top of where our Empty Game Object is and 00:12:18.730 --> 00:12:20.390 you can see it is highlighted. 00:12:21.590 --> 00:12:24.350 And then when I drop them, it creates this drop down menu. 00:12:24.350 --> 00:12:25.780 >> Awesome. You zoom in on that, 00:12:25.780 --> 00:12:28.720 it basically shows that game objects can be treated 00:12:28.720 --> 00:12:31.060 in a sense, kinda like folders. 00:12:31.060 --> 00:12:32.520 They can have sub objects and 00:12:32.520 --> 00:12:36.140 so you can organize them together by type, stuff that 00:12:36.140 --> 00:12:38.830 when you want it to move, you want it to move together. 00:12:38.830 --> 00:12:40.450 And so you can clear up your hierarchy. 00:12:42.860 --> 00:12:44.480 >> Yeah, I find it very convenient. 00:12:46.330 --> 00:12:49.020 So the next thing we're going to want to do is actually be able 00:12:49.020 --> 00:12:52.250 to distinguish this gray object from other gray objects cuz our 00:12:52.250 --> 00:12:56.110 arena just looks gray and sad and boring. 00:12:56.110 --> 00:12:58.780 So in the our assets we have our Scenes folder. 00:12:58.780 --> 00:13:03.189 I'm gonna create a new folder named Materials. 00:13:06.030 --> 00:13:07.730 Bet you guys can guess what we're gonna create in our 00:13:07.730 --> 00:13:09.110 Materials folder. 00:13:09.110 --> 00:13:10.220 >> Nice materials. 00:13:11.240 --> 00:13:12.640 >> Well, okay materials. 00:13:12.640 --> 00:13:16.710 >> [LAUGH] So what exactly is a material in Unity? 00:13:17.770 --> 00:13:23.282 >> So material is a very useful thing. 00:13:23.282 --> 00:13:26.519 If you ever want to decorate your 3D objects, 00:13:26.519 --> 00:13:29.922 in this case we're going to just give it a color so 00:13:29.922 --> 00:13:32.910 our 3D objects will all just be one color. 00:13:32.910 --> 00:13:34.860 But if you ever have like an image or 00:13:34.860 --> 00:13:39.070 a picture or like a texture of some sort you can just kind of 00:13:39.070 --> 00:13:44.200 create a picture of this and then drag it onto this game, 00:13:44.200 --> 00:13:49.990 your 3D game object and it will then texture your object. 00:13:49.990 --> 00:13:53.340 >> Yeah so you can bring in how you want the light to interact, 00:13:53.340 --> 00:13:57.160 what texture you're using, and bring it all together to 00:13:57.160 --> 00:14:00.460 tell the computer how you want this 3D object to be displayed. 00:14:00.460 --> 00:14:03.800 Since there's more than one way an object can be rendered. 00:14:03.800 --> 00:14:05.380 Is it really shiny? 00:14:05.380 --> 00:14:06.410 Is it really glossy? 00:14:06.410 --> 00:14:07.943 Do you have bump maps on it so 00:14:07.943 --> 00:14:11.110 that the shadows interact in a different way? 00:14:11.110 --> 00:14:13.420 But that's all stuff for a more advanced lecture, 00:14:13.420 --> 00:14:16.120 right now we are going to just make it a pretty color. 00:14:16.120 --> 00:14:18.950 >> I'll show you guys were some of these settings lie once we 00:14:18.950 --> 00:14:22.200 actually create our material. 00:14:22.200 --> 00:14:25.895 If you look, I brought up the menu by right-clicking, 00:14:25.895 --> 00:14:29.390 Create, and instead of folder were going to scroll down 00:14:29.390 --> 00:14:30.596 to where it says Material. 00:14:30.596 --> 00:14:34.950 You can kind of take my word that that was Material. 00:14:34.950 --> 00:14:39.220 New material is going to be Ground Material, 00:14:39.220 --> 00:14:40.750 probably our material for the ground. 00:14:40.750 --> 00:14:45.380 I'm gonna create another New material and 00:14:45.380 --> 00:14:49.339 I'm going to name this one Collectible Material, for our 00:14:49.339 --> 00:14:53.630 collectibles that we are going to be collecting in this game. 00:14:53.630 --> 00:14:57.660 So, now we need to assign it a color and we do this by when you 00:14:57.660 --> 00:15:00.600 click on it, in our inspector, this menu pops up. 00:15:02.380 --> 00:15:04.520 And over here, there's like a little color selector 00:15:05.710 --> 00:15:08.650 if you click on it, it brings up a color selector. 00:15:08.650 --> 00:15:10.010 >> That's handy. 00:15:10.010 --> 00:15:11.070 >> I know. 00:15:11.070 --> 00:15:13.640 I'm going to make my ground material blue. 00:15:13.640 --> 00:15:17.750 And then my collectible material I'll make green. 00:15:21.510 --> 00:15:23.700 So now, here's the toughest part. 00:15:23.700 --> 00:15:25.040 You guys have to watch carefully here. 00:15:26.330 --> 00:15:29.250 As we drag our ground material into our scene. 00:15:30.680 --> 00:15:31.240 There we go. 00:15:31.240 --> 00:15:33.390 It gives me the option. 00:15:34.930 --> 00:15:36.390 >> And it knows automatically what 00:15:36.390 --> 00:15:38.060 object you're hovering that material over and 00:15:38.060 --> 00:15:41.260 it says, you wanna apply this material to that object. 00:15:41.260 --> 00:15:42.620 >> Exactly.

setup correctly, I changed my directional lighting 00:16:37.020 --> 00:16:43.400 just, make sure that my rotation is x 50, 00:16:43.400 --> 00:16:46.490 y 60 just because the delay that it ends up lighting are seen. 00:16:46.490 --> 00:16:47.640 >> Yes, cuz it looks nicer. 00:16:47.640 --> 00:16:50.156 But something of course you can tweak on your own. 00:16:50.156 --> 00:16:53.790 >> Feel free to play around with these values. 00:16:53.790 --> 00:16:55.730 So the next thing we're going to do is actually create our 00:16:55.730 --> 00:16:56.940 collectible. 00:16:56.940 --> 00:16:59.660 We are going to do this by right-clicking and 00:16:59.660 --> 00:17:01.880 creating another cube. 00:17:01.880 --> 00:17:02.990 3D Object > Cube. 00:17:05.690 --> 00:17:07.940 I'm going to rename this cube, Collectible. 00:17:09.740 --> 00:17:11.240 That does not say collectible. 00:17:12.570 --> 00:17:13.080 Not this. 00:17:14.508 --> 00:17:16.660 So our collectible is now invisible on our field, 00:17:16.660 --> 00:17:21.090 if I reset its origin point, it now you can actually see it. 00:17:21.090 --> 00:17:22.150 It pops into view. 00:17:22.150 --> 00:17:23.756 >> You can also reset it, but 00:17:23.756 --> 00:17:27.406 instead of having to manually go in and type zero zero zero, 00:17:27.406 --> 00:17:30.326 there's a little gear next to that component, 00:17:30.326 --> 00:17:33.406 in the editor and you can click that and hit Reset. 00:17:33.406 --> 00:17:35.657 It'll automatically zero everything out for you. 00:17:35.657 --> 00:17:41.282 >> Yeah, pretty much. 00:17:41.282 --> 00:17:44.311 So right now it's just kind of just sitting in the middle 00:17:44.311 --> 00:17:46.888 of our field, I'm just gonna raise it up a bit so 00:17:46.888 --> 00:17:49.520 we can see if we zoom in our scene view. 00:17:49.520 --> 00:17:52.610 It's kinda hovering over our ground 00:17:52.610 --> 00:17:55.240 instead of being in our ground. 00:17:55.240 --> 00:17:59.992 And I'm just going to change its rotation to 45, 45, 45. 00:17:59.992 --> 00:18:01.954 And you can see in our game view, 00:18:01.954 --> 00:18:04.150 that looks much more collectibly. 00:18:05.920 --> 00:18:08.700 >> Which reminds me of those collectibles in Mario Kart 64 00:18:08.700 --> 00:18:12.800 but I might have played that at a very impressionable age. 00:18:12.800 --> 00:18:15.790 Well I don't know, I think those Mario Kart collectibles 00:18:15.790 --> 00:18:19.050 are just very, they just like scream collect me. 00:18:19.050 --> 00:18:21.770 So that's the impression we are going to want to give as well. 00:18:21.770 --> 00:18:25.160 >> Nice simple shape but 00:18:25.160 --> 00:18:27.350 shows something cool is going on there. 00:18:27.350 --> 00:18:28.925 >> Also if you haven't saved yet, please save. 00:18:28.925 --> 00:18:29.660 >> Yes. 00:18:29.660 --> 00:18:32.140 Hit Ctrl+S often. 00:18:32.140 --> 00:18:36.056 Yes, so in our assets we have Materials, Scenes, 00:18:36.056 --> 00:18:40.531 now we're going to create a third folder called Scripts. 00:18:43.532 --> 00:18:45.990 >> This is where we're gonna put some code in, right? 00:18:45.990 --> 00:18:49.680 >> Right, exactly, we are going to write our first bit of code. 00:18:49.680 --> 00:18:53.010 And we're going to do this in our Scripts folder. 00:18:53.010 --> 00:18:57.450 We are going to Create > New C Sharp script. 00:18:57.450 --> 00:19:02.080 Right here, second option in my Unity editor. 00:19:02.080 --> 00:19:06.210 I am going to name this script ItemRotator. 00:19:06.210 --> 00:19:12.520 And you can see once I zoom in, I have camel cased it. 00:19:13.660 --> 00:19:17.290 Which means that the beginning of each word 00:19:17.290 --> 00:19:20.230 has a capital letter to be able to distinguish it. 00:19:20.230 --> 00:19:23.748 Item with a capital I, Rotator with a capital R. 00:19:23.748 --> 00:19:28.610 If I double-click this script right now it's 00:19:28.610 --> 00:19:32.930 going open in My Favorite Editor, which in this case, 00:19:32.930 --> 00:19:35.330 by default, is set to Visual Studio. 00:19:35.330 --> 00:19:37.530 Turns out that's also my favorite editor. 00:19:37.530 --> 00:19:39.310 If you're using a Mac, 00:19:39.310 --> 00:19:42.604 it's probably going to open Mono Develop. 00:19:42.604 --> 00:19:47.248 It will behave very similarly so you'll be able to write the code 00:19:47.248 --> 00:19:51.032 in the same way because you'll be able to see the same 00:19:51.032 --> 00:19:54.479 thing pop up on Mono Develop and Visual Studio. 00:19:54.479 --> 00:19:57.884 And you could also use the visual studio code, 00:19:57.884 --> 00:20:01.800 our light weight editor on a Mac or Windows as well. 00:20:01.800 --> 00:20:03.820 But it requires a little bit of extra work, 00:20:03.820 --> 00:20:08.080 but again that is not the scope of this talk. 00:20:08.080 --> 00:20:12.050 >> Right, so right now by default, whenever we create 00:20:12.050 --> 00:20:15.660 a new C# Script, this is what it automatically generates. 00:20:15.660 --> 00:20:18.830 Using UnityEngine, using System.Collections, 00:20:18.830 --> 00:20:21.800 public class, whatever you named your script, 00:20:21.800 --> 00:20:26.160 extends MonoBehavior, start function, update function. 00:20:26.160 --> 00:20:28.640 >> It's important to note that it makes it based on 00:20:28.640 --> 00:20:31.370 what you first named the script and often I see people who 00:20:31.370 --> 00:20:34.460 are new to Unity will make a C# Script, and 00:20:34.460 --> 00:20:36.860 just kind of like as you were typing earlier, I had a typo. 00:20:36.860 --> 00:20:40.040 Let me just rename that file and fix that, but then they don't 00:20:40.040 --> 00:20:44.250 actually rename the typo and the script file that was created, 00:20:44.250 --> 00:20:46.450 and the class is a different name than the filename. 00:20:46.450 --> 00:20:49.411 And so it's important to double-check that those two 00:20:49.411 --> 00:20:50.190 names match. 00:20:50.190 --> 00:20:52.560 Whatever they are, they should match. 00:20:52.560 --> 00:20:53.530 >> Yep, definitely. 00:20:54.790 --> 00:20:59.642 As you can see up here, if I had kind of named it 00:20:59.642 --> 00:21:05.130 something wrong, and then try to edit it back 00:21:05.130 --> 00:21:09.190 in the Unity editor, this would have still said ItemRotator. 00:21:09.190 --> 00:21:10.135 It wouldn't have updated. 00:21:10.135 --> 00:21:13.807 So you would have to update that yourself to make sure that it's 00:21:13.807 --> 00:21:14.648 consistent. 00:21:14.648 --> 00:21:15.503 >> Kind of a tangent, 00:21:15.503 --> 00:21:17.641 but it is a common question I get with people, so 00:21:17.641 --> 00:21:18.795 I wanted to point it out. 00:21:18.795 --> 00:21:21.040 >> Yep. 00:21:21.040 --> 00:21:24.000 So as this Start Function anything 00:21:24.000 --> 00:21:25.680 that needs to be initialized, or 00:21:25.680 --> 00:21:28.610 anything that you would want to happen at the start of the game 00:21:28.610 --> 00:21:30.230 will go in here. 00:21:30.230 --> 00:21:33.430 An update is called Once Per Frame. 00:21:33.430 --> 00:21:37.640 Which means that at every frame this code will execute. 00:21:37.640 --> 00:21:40.700 Now, it's kind of important that we distinguish frame 00:21:40.700 --> 00:21:42.260 versus time. 00:21:42.260 --> 00:21:48.470 So frame rate will differ depending on what computer 00:21:48.470 --> 00:21:51.640 you're on or the settings of how you're running your game. 00:21:51.640 --> 00:21:54.302 It's not really consistent across machines however, 00:21:54.302 --> 00:21:56.120 time is a universal constant. 00:21:56.120 --> 00:22:00.600 So, if you ever want to have something like movement, 00:22:00.600 --> 00:22:04.540 lets say, movement probably should not be updated per frame, 00:22:04.540 --> 00:22:06.945 but rather based on time. 00:22:06.945 --> 00:22:08.266 >> Mm-hmm. >> Because otherwise 00:22:08.266 --> 00:22:10.080 you're gonna have blocky movement. 00:22:10.080 --> 00:22:12.752 >> Now, you still might want to have that in your update 00:22:12.752 --> 00:22:15.363 code but you just will then have to factor in how much 00:22:15.363 --> 00:22:17.260 time has passed. 00:22:17.260 --> 00:22:18.360 >> Exactly. 00:22:18.360 --> 00:22:23.548 So right now we are going to add one line of code under update. 00:22:26.697 --> 00:22:31.718 And it is going to be transform with the lowercase t, 00:22:31.718 --> 00:22:35.141 dot rotate with an uppercase R, and 00:22:35.141 --> 00:22:39.834 then in parenthesis new Vector with a capital V. 00:22:39.834 --> 00:22:41.690 V Vector 3. 00:22:42.970 --> 00:22:49.070 And then in those parentheses, 15, 30, 45. 00:22:49.070 --> 00:22:53.365 Outside those parentheses, star, which means multiply, 00:22:53.365 --> 00:22:57.932 times time dot delta time. 00:23:00.117 --> 00:23:01.640 >> Excellent. 00:23:01.640 --> 00:23:03.480 What is delta time Medina? 00:23:03.480 --> 00:23:04.410 >> Yeah, what did I just write? 00:23:04.410 --> 00:23:06.400 Let's break this down really quickly. 00:23:06.400 --> 00:23:09.680 First off, save and you can see Visual Studio tells me that I've 00:23:09.680 --> 00:23:11.750 saved because this jumps to green. 00:23:13.270 --> 00:23:16.720 So let's break down this line of code right here. 00:23:16.720 --> 00:23:19.990 Transform which as you recall, when we were looking 00:23:19.990 --> 00:23:23.670 at the inspector, our transform has three different properties. 00:23:23.670 --> 00:23:28.010 Our transform has position, rotation, and scale. 00:23:28.010 --> 00:23:31.220 So transform.Rotate is probably going to change it's rotation. 00:23:32.720 --> 00:23:33.850 >> Makes sense. 00:23:33.850 --> 00:23:38.798 >> Our Vector 3 which I very just poorly highlighted has our 00:23:38.798 --> 00:23:40.930 X, Y, and Z values. 00:23:40.930 --> 00:23:45.065 X being 15, Y, being 30, Z being 45. 00:23:45.065 --> 00:23:47.970 >> Mm-hm, it's just a collection of those three numbers just like 00:23:47.970 --> 00:23:51.560 in math as a three dimensional vector for how we're going 00:23:51.560 --> 00:23:54.550 to rotate it in 3D space >> Exactly, 00:23:54.550 --> 00:23:57.768 now why are we multiplying it times time.deltaTime? 00:23:57.768 --> 00:24:00.950 Well time.deltaTime actually, if you hover over it in 00:24:00.950 --> 00:24:03.970 Visual Studio, it'll- >> That's some nice 00:24:03.970 --> 00:24:05.710 IntelliSense highlighting. 00:24:05.710 --> 00:24:07.480 >> Yeah, IntelliSense highlighting will actually tell 00:24:07.480 --> 00:24:09.390 you straight up right here 00:24:09.390 --> 00:24:12.660 the time in seconds it took to complete the last frame. 00:24:12.660 --> 00:24:13.710 Well that's really convenient. 00:24:13.710 --> 00:24:15.850 That means I don't have to calculate between frame rates 00:24:15.850 --> 00:24:16.930 all by myself. 00:24:16.930 --> 00:24:18.390 Thanks Unity. 00:24:18.390 --> 00:24:19.230 >> Automatically handles that. 00:24:19.230 --> 00:24:20.270 That's great. 00:24:20.270 --> 00:24:23.831 >> Great, so now we are rotating it not based per frame but 00:24:23.831 --> 00:24:25.155 actually per time. 00:24:28.162 --> 00:24:32.308 So now if we go back to our Unity editor, you can actually 00:24:32.308 --> 00:24:37.074 click on item rotator and in the inspector it'll pop up that your 00:24:37.074 --> 00:24:41.720 code has changed and now we have our newly added line of code. 00:24:41.720 --> 00:24:43.590 >> Mm-hm, in real time. 00:24:43.590 --> 00:24:44.190 >> In real time. 00:24:45.880 --> 00:24:50.180 If you don't see that in real time you might want to refresh 00:24:50.180 --> 00:24:54.090 over here I right-clicked, and where we have Create, Refresh. 00:24:54.090 --> 00:24:56.720 >> And also make sure it saved into Visual Studio, because I've 00:24:56.720 --> 00:24:59.470 often had that where I'm like, wait, why didn't my code work? 00:24:59.470 --> 00:25:01.050 Yeah, I forgot to save. 00:25:01.050 --> 00:25:02.140 >> Right. 00:25:02.140 --> 00:25:06.290 So now we can drag item rotator onto collectible. 00:25:06.290 --> 00:25:09.106 >> So just like with the material that you just drag and 00:25:09.106 --> 00:25:11.202 drop onto the hierarchy at this time, 00:25:11.202 --> 00:25:14.415 and it'll create a new component onto that game object. 00:25:14.415 --> 00:25:16.950 >> Right, and if you click on it in the inspector 00:25:16.950 --> 00:25:19.186 item rotator should now be on there. 00:25:19.186 --> 00:25:20.840 >> Excellent. 00:25:20.840 --> 00:25:21.580 >> If we click play. 00:25:23.820 --> 00:25:24.806 Look at that, it's rotating. 00:25:24.806 --> 00:25:28.325 >> It's rotating the 3D, that's great. 00:25:28.325 --> 00:25:28.876 >> Great. 00:25:30.160 --> 00:25:31.210 >> It's exactly what we wanted. 00:25:31.210 --> 00:25:33.140 Always good when the code works first time. 00:25:33.140 --> 00:25:34.720 >> I know. 00:25:35.830 --> 00:25:39.970 So there's gonna be one more thing that I do real quick. 00:25:39.970 --> 00:25:42.620 And that is, remember when we made that collectible material? 00:25:42.620 --> 00:25:44.940 >> Mm-hm. >> I made mine green. 00:25:44.940 --> 00:25:47.500 So if I drag it onto collectible, now it's green. 00:25:47.500 --> 00:25:48.040 >> There we go. 00:25:49.160 --> 00:25:50.830 >> Cool. >> Now it rotates and 00:25:50.830 --> 00:25:52.110 it looks pretty. 00:25:52.110 --> 00:25:53.640 >> I know, it's really great. 00:25:53.640 --> 00:25:56.140 It's almost feels like we're making a game here. 00:25:56.140 --> 00:26:01.308 >> Almost. >> Almost, so real quick. 00:26:01.308 --> 00:26:04.900 We're going to make our game we just made, 00:26:04.900 --> 00:26:07.660 as you saw one screen kind of popped up when I pressed play. 00:26:07.660 --> 00:26:10.070 Now we're going to make it look like VR 00:26:10.070 --> 00:26:12.370 where it projects into each eye. 00:26:12.370 --> 00:26:13.570 >> Excellent. 00:26:13.570 --> 00:26:16.940 >> Awesome, so the first step to making it VR capable is 00:26:16.940 --> 00:26:18.620 delete your main camera. 00:26:18.620 --> 00:26:20.510 >> No, why are we deleting that? 00:26:20.510 --> 00:26:22.480 Don't we need it? >> Because, yeah we do need it. 00:26:22.480 --> 00:26:23.890 But we don't need that one. 00:26:23.890 --> 00:26:28.020 Actually, we need a special Google Cardboard camera, which 00:26:28.020 --> 00:26:32.320 under our Cardboard assets, and under a folder called Prefabs, 00:26:33.500 --> 00:26:36.850 there's going to be a special prefab called CardboardMain. 00:26:36.850 --> 00:26:39.150 >> And this is the stuff that we imported back in the beginning 00:26:39.150 --> 00:26:40.550 of the project. 00:26:40.550 --> 00:26:44.010 >> Right, so if we drive CardboardMain into our scene. 00:26:44.010 --> 00:26:47.360 You kinda see a new camera's here. 00:26:47.360 --> 00:26:50.160 >> And this one's special because there are technically 00:26:50.160 --> 00:26:51.430 two cameras attached to it. 00:26:51.430 --> 00:26:53.850 One for the left eye, and one for the right eye. 00:26:53.850 --> 00:26:56.250 >> You can't see that right now but if you actually, 00:26:56.250 --> 00:27:00.460 in the hierarchy kind of drop down all of the drop down menus, 00:27:00.460 --> 00:27:04.130 you can kind of see under main camera. 00:27:04.130 --> 00:27:05.870 You have a main camera left and 00:27:05.870 --> 00:27:09.890 a main camera right, one for each eye under cardboard main. 00:27:11.400 --> 00:27:19.415 Cool, now if we press play >> That looks very 3D. 00:27:19.415 --> 00:27:22.414 >> Yes, but right now you can see it's projecting into each 00:27:22.414 --> 00:27:25.286 eye and the camera is now separated into the left eye and 00:27:25.286 --> 00:27:27.110 the right eye. 00:27:27.110 --> 00:27:28.690 >> Which of course looks a little weird on your 00:27:28.690 --> 00:27:30.140 computer screen. 00:27:30.140 --> 00:27:31.650 >> Right. >> It's also worth noting 00:27:31.650 --> 00:27:36.240 the concept of a prefab in Unity which is a collection of game 00:27:36.240 --> 00:27:41.170 objects components, property values that you can save as 00:27:41.170 --> 00:27:46.830 a file to then store in your editor and as you've seen here, 00:27:46.830 --> 00:27:49.970 that Google already ahead of time made these cameras, 00:27:49.970 --> 00:27:52.090 set it up just perfect for their settings, and 00:27:52.090 --> 00:27:54.801 then we got that file that we can drag back into our scene. 00:27:54.801 --> 00:27:58.364 >> Tufia, I was going to get there. 00:27:58.364 --> 00:28:00.146 >> Stepping on you. >> This pre-fab is like 00:28:00.146 --> 00:28:04.094 a template, a template that's very useful if you're creating 00:28:04.094 --> 00:28:06.300 multiple kinds of the same object. 00:28:06.300 --> 00:28:08.850 Which in our game, we're gonna have probably multiple 00:28:08.850 --> 00:28:11.730 collectibles so we're probably not going to want 00:28:11.730 --> 00:28:14.320 to have one game object over here that's collectible. 00:28:14.320 --> 00:28:16.870 We're going to want to have multiple templates of 00:28:16.870 --> 00:28:20.250 collectibles once we add more scripts and 00:28:20.250 --> 00:28:22.270 more properties to them. 00:28:22.270 --> 00:28:24.720 But we'll handle that in a bit. 00:28:24.720 --> 00:28:26.600 Right now we're not quite done with our main camera. 00:28:27.910 --> 00:28:31.050 So right now, if you select the main camera under cardboard 00:28:31.050 --> 00:28:34.980 main, scroll down, there's a component that we have to 00:28:34.980 --> 00:28:38.070 add under Add Component, all the way at the bottom. 00:28:39.800 --> 00:28:41.580 I'm going to click that. 00:28:41.580 --> 00:28:46.810 And in the search bar, PHY physics ray caster. 00:28:48.370 --> 00:28:50.280 Not the 2D one, there's a 3D one. 00:28:52.050 --> 00:28:54.090 The regular old, physics ray caster. 00:28:55.510 --> 00:28:58.540 And essentially, what this is doing is 00:28:58.540 --> 00:29:02.170 you guys remember from geometry, a ray is a line. 00:29:02.170 --> 00:29:04.660 So this is essentially 00:29:04.660 --> 00:29:09.420 going to invisibly point a line at any 3D object. 00:29:09.420 --> 00:29:12.430 It can tell us whether or not we're interacting with that. 00:29:12.430 --> 00:29:15.010 So it's a difference between our camera just kind of looking 00:29:15.010 --> 00:29:19.990 around in space versus am I touching this 3D object, 00:29:19.990 --> 00:29:21.740 am I touching it? 00:29:21.740 --> 00:29:22.380 Yes I am. 00:29:22.380 --> 00:29:25.100 >> Touching it based on the direction that your 00:29:25.100 --> 00:29:26.490 eye is facing. 00:29:26.490 --> 00:29:27.090 >> Right, so 00:29:27.090 --> 00:29:29.406 it's almost like there's a line shooting out from our camera. 00:29:29.406 --> 00:29:31.448 >> Makes sense. 00:29:31.448 --> 00:29:34.860 >> Yep, and there's one more thing that we have to do. 00:29:37.150 --> 00:29:41.160 In cardboard prefabs where we found cardboard main, there's 00:29:41.160 --> 00:29:45.130 one folder which, in my editor, is at the top, called UI. 00:29:46.200 --> 00:29:48.900 If we double click on that, there is one prefab that is 00:29:48.900 --> 00:29:52.000 in this folder, all alone, called cardboard reticule. 00:29:53.800 --> 00:29:56.060 And I will show you what a cardboard reticule is, 00:29:56.060 --> 00:29:58.720 real quick, but first we have to drag it and 00:29:58.720 --> 00:30:01.010 parent it under our main camera. 00:30:02.070 --> 00:30:05.740 So, what it should look like is Main Camera. 00:30:08.290 --> 00:30:11.356 And then, it should have three things underneath it. 00:30:11.356 --> 00:30:15.420 Our Main Camera Left, our Main Camera Right, and 00:30:15.420 --> 00:30:17.330 our CardboardReticle. 00:30:17.330 --> 00:30:21.030 And a reticle in VR essentially helps us 00:30:21.030 --> 00:30:23.650 figure out what we're looking at. 00:30:23.650 --> 00:30:25.080 And with paired with the ray caster, 00:30:25.080 --> 00:30:28.760 it can kind of tell us, are we looking at this 3D object? 00:30:29.860 --> 00:30:30.440 Yes, no? 00:30:33.500 --> 00:30:37.060 So this appears on, let me play our scene, 00:30:37.060 --> 00:30:40.170 this white dot that's now in the middle of our camera. 00:30:41.810 --> 00:30:43.510 And after we attach more scripts and 00:30:43.510 --> 00:30:47.910 more fun stuff, it'll actually expand when we're looking at 00:30:47.910 --> 00:30:49.570 a 3D object that we can interact with. 00:30:51.300 --> 00:30:51.828 Isn't that fun? 00:30:51.828 --> 00:30:54.854 >> Sounds great. 00:30:54.854 --> 00:30:57.870 >> So, last thing right now in our game view. 00:30:57.870 --> 00:30:59.540 See, this is why I like having the game view. 00:30:59.540 --> 00:31:03.710 We can kind of tell this is not really set up so 00:31:03.710 --> 00:31:05.540 that's fun to play our game. 00:31:05.540 --> 00:31:08.590 I'm going to reposition my camera so 00:31:08.590 --> 00:31:13.010 that we can actually kind of see our scene. 00:31:13.010 --> 00:31:14.500 >> As opposed to being in the middle of it we're 00:31:14.500 --> 00:31:16.480 kind of looking down at it. 00:31:16.480 --> 00:31:19.480 >> Right, cuz it kind of added it at zero zero zero. 00:31:19.480 --> 00:31:25.637 But it took me a while to play around with these values and 00:31:25.637 --> 00:31:29.960 you can feel free to put in your own, but 00:31:29.960 --> 00:31:35.988 I over here in the inspector set our position to be X 0, 00:31:35.988 --> 00:31:40.460 Y 11, Z -16 with a 45 X rotation. 00:31:41.770 --> 00:31:46.030 And it kind of, I think it makes it look good in our game. 00:31:47.400 --> 00:31:48.200 Sounds good to me. 00:31:48.200 --> 00:31:52.750 >> And this is actually going to be the end of part 1. 00:31:52.750 --> 00:31:56.346 We have set up our scene and made it VR capable, 00:31:56.346 --> 00:32:00.415 put the beginnings of the collectible in our scene. 00:32:00.415 --> 00:32:04.067 We're going to add in part two, you will see that we will 00:32:04.067 --> 00:32:07.181 actually make our collectible collectively, 00:32:07.181 --> 00:32:10.135 as well as add a game controller that will keep 00:32:10.135 --> 00:32:13.410 track of our score and a you win bit of text. 00:32:13.410 --> 00:32:14.290 >> Awesome, great. 00:32:14.290 --> 00:32:16.567 >> Well, then we'll see you all in part two.
