I actually used some additional sweep tests, it's not a bottleneck for me. And my suggestion would be to apply the gravity manually in each simulation tick, 'cause this way you can tweak it and make it exactly the way you want it! Character Controllers should be very simple to understand and tweak, ...

I actually don't want my character physics to match dynamic objects physics. The way a character should behave is far from the rigid body physics used in dynamic objects. So, you just have to implement only the physics that you actually want to apply in your character. I've only implemented gravity ...

I've implemented my own version of the KinematicCharacterController and it's working perfectly! I've dedicated some time on re-writing a lot of methods (and algorithms) from the btKinematicCharacterController (for optimization, adaption and correction). Now my character slides down slopes, doesn't j...

Thank you Erwin! Using the broadphase callback solved my problem perfectly (culling out the remaining objects is effortless!). My code looks like this now: struct AllButMeAabbResultCallback : public btBroadphaseAabbCallback { AllButMeAabbResultCallback(CollisionObject* me) : me(me) {} virtual bool p...

I'm implementing an object that pulses away any other object within a radius. What's the best (high performance) way to do this search? P.S.: Iterating over all objects and checking if it's distance from my pulsing object is lesser than the radius is obvious...I'm trying not to do this! P.S. 2: Coll...

I have some kinematic objects in my code, and also, some characters (represented as GhostObjects). The characters are being included in the DynamicsWorld as: PhysicsManager::getInstance()->getDynamicsWorld()->addCollisionObject( ghostObject, btBroadphaseProxy::CharacterFilter, btBroadphaseProxy::All...
