AllConvexResultCallback #75

Closed nagedev closed 4 years ago

nagedev commented 4 years ago

As I understand, ConvexResultCallback is inherited by only one class (ClosestConvexResultCallback), and because of that ConvexSweepTest returns only closest result, which means that there's no way to get All collisions

Is there any way to do some shape cast that returns all collisions?

Have you tried using a ghost object? I think you can:

Create a ghost object Add your casting shape Move it and there should be a collision pair cache that has all the collisions.

That works! I thought it would require calling StepSimulation, but it works perfectly without it Thanks
