You can look into using Box2D. I use that in several of my projects.
Especially in games like racing games, there's ways to construct the world
so it only requires 2D physics.

Hi,
There have been a number of posts on collision detection in Away3D but
I still havent found a satisfactory answer to my issue.
I am creating a simple driving game where I am moving a Camera around
a track. Simple movement is done with the keyboard e.g
* Up Key calls camera.moveForward(x)
* Right Key calls camera.pan(x) etc
I will have about 100 objects placed around the world (setup as simple
cubes) and I am trying to implement some simple collision detection
with the camera and these objects.
From what I have seen there are a number of options:
Physics engine such as Jiglib - This is not feasable as I need to port
this game to another platform afterwards so I want to avoid reliance
on a physics engine.
CollisionMap - not feasable for same reason as above. No Collision
Maps available on other platform.
I have also played around with the Ray class but not had much luck.
At any point I know the camera position, what I need to work out is
what the new position of the camera will be when I call the next
camera.moveforward(x) command? How do I work this out? Bearing in mind
that the camera.pan(x) calls, when turning right or left, will have
affected the rotations, transformations etc of the camera.
Once I know what the camera position is now and what the camera
position will be the next time I move forward, I then just need to
work out if the camera will cross one of the faces of the cube
objects.
I know the theory of what I want to do but not sure of the math/
function calls I can use to achieve it.
I would really appreciate any help you guys can give me.
Many Thanks!
