Towing a trailer

[barrax]

Hi

Wondering if someone can help with the beginnings of my lorry-towing-truck game engine.

I'm using some inverse kinematic code at the moment - just to calculate the distance and rotations.

Take a look at the attached swf and pretty soon you'll see what im trying to do. (arrow keys to move)

Problem is that it looks wierd with the trailer sliding around. Does anyone know of a url/resource/approach i can use to make this look more believable? Like adding in constraints, mass ...or anything! Ive tweaked around some figures but its all been guesswork.

Cheers,
B
