Hi again,

My problem is still not solved. Please help me.

Hi again,

Isn't running your app at 60fps not an option? If it isn't, I'd try to test it anyway, to see if the problem solves. If it does, we'll have to work around it.

Hi Kate, I had the same problem before in my app, or something very similar, and, as you point, it was caused by the fact I updated my objects' position in my world more often than in the bullet world. Have you tried to step your simulation at the same rate you update your objects' position? say, on...

Hi everyone, I'm having problems programming a fast moving character in my game. It penetrates walls, sometimes going through them, as it increases speed. I have read other topics such like this one that talk about bullets or similar fast moving objects, those being always Rigid Bodies (if i underst...

If pManifold == NULL then the objects didn't collide. Anyway, seriously, if your world is wide or you're calling this code quite often, I wouldn't recommend it as it creates memory leaks.

Looking at your code, I don't really see a mistake. Did you call performDiscreteCollisionDetection() before? However, the general approach is probably a little overkill, testing the whole scenery just for two bodies... The way I do collision detection between two objects is this. btCollisionAlgorit...

Thank you very much for the fast feedback. The problem is solved and it saved my life today.

Hi everyone, I have been working on Bullet for a few days and I got stucked with something strange. As far as know, kinematic controllers are meant to move user controlled collision objects, such as players, enemies or moving platforms. I'm working on a game where I need to move, rotate and do diffe...
