What do you mean by "too early" ?

The problem can be seen in the picture. This is already a collision and I don't know why.. The collision is happening with the cactus. Cubes are working fine -> collision with spaceship only detected when actually collided.
Any ideas?

Cheers

Omg... that was actually it. I was using a debugdrawer for the physics world which was slowing down the frame-rate. Damn.. that took me ages to figure it out.

Thanks again.

Cheers

The cost of adding a new object to the world scales approximately by Order(N), but it was my understanding that it wasn't really a problem until you started to get up to around 10k objects. Hi! No the problems occur way earlier. It takes me around 10 seconds to get from 170 fps to 40 fps while runn...

Ok, never mind... it already works. I am quite new to this. If I change the shipCollidesWith variable, no collisions are detected.

But still there is still the problem that the collision is detected way too early and I have no idea why..

Hi! I have a spaceship an cubes. I am adding those to the dynamicsWorld like so: #define BIT(x) (1<<(x)) enum collisiontypes { COL_NOTHING = 0, //<Collide with nothing COL_GROUND = BIT(0), //<Collide with ground COL_WALL = BIT(1), //<Collide with walls COL_CUBE = BIT(2), //<Collide with powerups COL...

if the cubes are same and use same shape, you can use same shape for all cubes...without create new shape for new cube... a possible pseudo code btCompoundShape *G_BTPhysics::GetBModelShape (int index) { for (uint32 i = 0; i < bmodels.Count(); i++) // check if already exist if (bmodels[i].Index == ...

Hi! First of all: I am new to this. But it would be amazing if guys could help me out. I am creating a lot of cubes (>7000). Each frame an update method is called where a cube is created and a rigidBody is added to the cube. After around 200 cubes the bodies, rigidbodies stop being created. Also FPS...
