wheel

Hey, I have a wheel segmented into 8 pie pieces, and a picker that is pointing at the currently selected segment (think wheel of fortune). I want to highlight the currently selected segment, and so have started to use Chipmunk to construct the 8 segments, attached to a rotating body, and then the picker that is put in a position to collide with each of the segments. The trick is, how do you allow the picker to pass over top of the segments, while still getting the collision, but not actually colliding and slowing down the wheel?

I haven't started down this path yet, but thought this may solve the problem: removing the colliding segment and then putting it back after the picker has started colliding with another segment a bit away (like two segments away).

There may be a much simpler solution not even involving Chipmunk that I haven't thought of. Thanks,

Andrew

Collision Detection algorithms with early Collision exit

I'm using collision detection in Monte Carlo simulations and at the moment I'm using GJK which is quite fast. I can't help to think it could be done even faster though. In the simulations, about 70% of the time GJK is run, it detects a collision. Thus collisions are more than non-collisions in my… >>> More

I am working on a top down 2.5D game. In the game anything that overlaps on the screen should be 'colliding' with each other regardless of whether they are on the same plane in the 3D world.

I have a very basic problem with Box2D. For a arenatype game where you can throw scriptable "missiles" at other players I decided to use Box2D for the collision detection between the players and the missiles. Players and missiles have their own circular shape with a specific size (varying). But I… >>> More
