Hey, I know this is a stupid question, but I haven't gotten it working yet, so can someone tell me how to get the character's animation to change to walking while walking, and stop while stopped? Please respond soon, thanks
In the icon file you need to double click below and click movement so it's in movement state

You can also look at index.html#AT if you want smoother animation when mobs move faster than the icon can update.

This is a fairly advanced concept though. You may want to put it off until you have a firmer grasp of DM.
