Question by lucaoo · Sep 30, 2011 at 11:50 PM · 2dphysicscar

2D Car Help

Hi everyone! I just started using Unity and I'm trying to make a very simple 2D physics car game (for learning purposes). Below is the .rar file of my project:

http://www.4shared.com/file/4TIs7I7I/2d_Car.html

Keys: Up - Accelerate; Down - Break; Right and Left - Rotate

I would like to clarify some doubts:

  1. How do I make the car stop by friction when I let the accelerate key? Do I have to script? Like checking if it is on ground and adding a force based on the speed.

  2. Why is the collision between the wheel and the ground odd sometimes? For example, when you stay on just the rear wheel.

  3. Is there any good 2D car tutorials? I did the script myself, but like I said, I'm very newb at Unity!

Thanks for the attention.
