I've created an extremely basic little program that is meant to move a simple stickman model forward until he collides with a hut 500 units away. there's just a basic box around the hut, so the open door should still repel him. Problem is, he won't move!
The strangest thing is that I compiled this once and it worked just fine. The second time, and every time since then, it's failed to move.
I'll attach a zip file with the media I'm using plus the code. Here's the snippet as well for whoever's interested.
