Thanks for the comments. I can certainly do a video on using MongoDB without Mongoose or Monk or any of the others. keep an eye out for it, I will do it right after I upload the series of setting up your MongoDB instances.
He is "always running" because of his sprite. If you open up sprPlayerRunning and click on Edit Sprite you will see all of his positions. Click on the Show Preview and you will see him running.
You can stop the running by swapping out the sprite with one that is static... or in a standing motion (swaying back and forth).
In addition to this, you will find when you open the room, a background tab. Each background has a different speed and is tiled horizontally. This gives the illusion of movement. ( a negative number will move to the left)
