I've really tried all the possible way to collisiosn detection with IAnimatedMeshSceneNode .... but with no result ..

Still the camera fly thrugh my SceneNode, and it doesn't colide with it!

Any help please!

here is the code

Code: Select all

int main()
{
....
....
....
IAnimatedMesh* mesh = smgr->getMesh("../../media/sydney.md2");
	IAnimatedMeshSceneNode* node = smgr->addAnimatedMeshSceneNode( mesh );

if (node)
{
	node->setMaterialFlag(EMF_LIGHTING, false);
	node->setFrameLoop(0, 310);
	node->setMaterialTexture( 0,  driver->getTexture("../../media/sydney.bmp") );
}

ICameraSceneNode* camera;
camera = smgr->addCameraSceneNodeFPS();
device->getCursorControl()->setVisible(false);
camera->setPosition(vector3df(-100, -100, 100));
	
ITriangleSelector* selector;
selector = smgr->createTriangleSelectorFromBoundingBox(node);
	
ISceneNodeAnimator* anim;
anim = smgr->createCollisionResponseAnimator
           (selector, node, vector3df(50, 50, 50), vector3df(0, 0, 0),     vector3df(0, 20, 0), 0.000500);

node->addAnimator(anim);

while(device->run())
{
	driver->beginScene(true, true, SColor(255,100,101,140));
	smgr->drawAll();
	guienv->drawAll();
	driver->endScene();
}
return 0;

}

I'm not sure, but try this

Code: Select all

	
ITriangleSelector* selector;
selector = smgr->createTriangleSelectorFromBoundingBox(node);

[color=red]
node->setTriangleSelector(selector);
selector->drop();
[/color]

ISceneNodeAnimator* anim;
anim = smgr->createCollisionResponseAnimator
           (selector, node, vector3df(50, 50, 50), vector3df(0, 0, 0),     vector3df(0, 20, 0), 0.000500);

No, adding

node->setTriangleSelector(selector);
selector->drop();

Didn't solve the problem, still the camera fly though Sydeny!

Proceed as adviced by LM, and additionally change 'node' to 'camera' in the collisionResponse, otherwise the node can only coolide with itself.

replace:
anim = smgr->createCollisionResponseAnimator
(selector, node, vector3df(50, 50, 50), vector3df(0, 0, 0), vector3df(0, 20, 0), 0.000500);

node->addAnimator(anim);

with:

anim = smgr->createCollisionResponseAnimator(selector, CAMERA, core::vector3df(5,5,5),core::vector3df(0,0,0), core::vector3df(0,0,0));
CAMERA->addAnimator(anim);
anim->drop();

Thanx very much .. for both LiM and Hybrid ...
the collision detection between the Camera and IAnimatedMeshSceneNode now works 100% ...

I need to collision detection with IAnimatedMeshSceneNode!
