Hello,
I copy/pasted my code from a single file into multiple files to make it cleaner, I haven't changed anything from the collision animators and triangle selectors and it does that...

I don't bounce on the ground but I bounce on the floor, weird...
I'm sure I missed something but I don't really see what.

Here's the ground's code (where I don't bounce):

Code: Select all

	IAnimatedMesh * groundMesh = CynEngine->getScene()->addHillPlaneMesh("Plane", dimension2d<f32>(100.0f, 100.0f), dimension2d<u32>(100,100), 0, 0, dimension2d<f32>(0,0), dimension2d<f32>(250,250));
	ground = CynEngine->getScene()->addAnimatedMeshSceneNode(groundMesh);
	ground->setPosition(vector3df(0,0,0));
	ground->setMaterialTexture(0, CynEngine->getDriver()->getTexture("./assets/textures/grass/grass002.jpg"));

	groundSelector = CynEngine->getScene()->createOctTreeTriangleSelector(groundMesh->getMesh(0), ground, 128);
	ground->setTriangleSelector(groundSelector);

	ISceneNodeAnimator *groundAnim = CynEngine->getScene()->createCollisionResponseAnimator(
			groundSelector, CynEngine->getCamera()->getNode(), vector3df(3,5,3),
			core::vector3df(0,-5,0));
	CynEngine->getCamera()->getNode()->addAnimator(groundAnim);
	groundAnim->drop();
	groundSelector->drop();

Here's the floor's code (where I bounce) :

Code: Select all

	node = CynEngine->getScene()->addMeshSceneNode(mesh);
	node->setPosition(position);
	selector = CynEngine->getScene()->createTriangleSelector(mesh, node);
	node->setTriangleSelector(selector);
	anim = CynEngine->getScene()->createCollisionResponseAnimator(selector, CynEngine->getCamera()->getNode(), vector3df(3,5,3), vector3df(0,-5,0));
	CynEngine->getCamera()->getNode()->addAnimator(anim);
	anim->drop();
	selector->drop();

Thanks for your replies !

It looks like you are adding two collision response animators to the camera. I'd be willing to bet that this is your problem. If you want to have collision with multiple different objects, you need to use one collision response animator and IMetaTriangleSelector. If you do a search, you should find examples of how to do it.

Thanks, it was that indeed.
