I tried to add a sprite but it was to big and it was ina white frame.
i did everything you did with a floor parent and player objects with gravity and check for object, but my player continued to float there, how do I get him to fall
ok so idk what was wrong, but I started a new program and it worked fine, thanks
I am using Gamemaker 8.1. Am I able to complete these tutorials with it? Also, I am running Windows 7 -- does it matter if I am not using Windows 8?
