I found it. You need to make the body do constant collision detection like this:

Code:

body.setCcdMotionThreshold(0.015f);body.setCcdSweptSphereRadius(0.01f);

Bullet collision failing with fast moving bodies

2021-12-23T20:55:57+00:00

Hello, I am creating a 3D space shooter game using OpenGL and Bullet physics. I have a problem with fast moving projectiles. I am simulating a laser particle using a capsule shape. The problem is that this body penetrates objects some times and even pass through them, possibly because it is moving too fast for the physics engine. What can I do about that? Here is how I create the world :

Code:

mpBroadphase = new btDbvtBroadphase();// Set up the collision configuration and dispatchermpCollisionConfiguration = new btDefaultCollisionConfiguration();mpDispatcher = new btCollisionDispatcher(mpCollisionConfiguration);// The actual physics solvermpSolver = new btSequentialImpulseConstraintSolver;// The world.mpDynamicsWorld = new btDiscreteDynamicsWorld(mpDispatcher, mpBroadphase, mpSolver, mpCollisionConfiguration);
