Box2D Forums

Hello, I'm new to Box2D and am wondering if this is going to be the right application for me. I'm impressed with the collision detection and built in physics, but it's been a little confusing for me.

I'm trying to make a game for iPhone using Box2D and I'm using the accelerometer to move an object around a top-down view map. Think labyrinth almost, but with a slower moving character. Is something like this possible with Box2D? I've been trying to tweak the gravity, but I want the character to turn and change directions a lot quicker. Are there any good tutorials out there?

Thanks for the help

Thinking of it from a gameplay standpoint, I would say that the slow change of gravity would add to the difficulty. Buuuuuuuuuut, if you really wanted to change the gravity quicker, you could set tthe game to read the accelerometer and then set the gravity using a scalar and then adjust that. For example, if you were holding the phone like a GBA and tilting it (which is what I'm assuming you are doing), you could set gravity to:
