Box2D Forums

Hi,

I was looking for a good tutorial about box2d and creating some vehicles, but couldn't find a good example for iPhone. Only one link for Flash:
http://www.emanueleferonato.com/2009/04 ... ox2d-cars/

Can some one give an example of such vehicle like Emanuele Feronato gives, but for iPhone? Also I'm interested in creating vehicles like this :


So, with independent suspension for each wheel.

The wheel joint does a good job of this. Check out the 'car' test in the testbed for a simple usage example in C++.

Can you please point directly to this? I'm a noob with box2d currently...

Build and run the testbed, then select 'Car' from the list of tests. Specifically, the test is this one:

Oh, thank you!
Box2d manual must be with detailed description of this. Currently it's so poor.

Ok. I've started some project to build a car.
However I have a very strange issue, when the car body is small. Car start jumping, rotating... well it's do crazy things) How this can be fixed?
I need such small size car body for my game.

It looks like the joint anchor position is not in the center of the wheels.
I think you'll also need to make the car body much heavier compared to the wheels if you want to keep it stable.
