collision problem

[lobbin]

I followed the collision tutorial slightly changed, it isn't that camera but a user-controlled node that should be affected but I can't get it to work

This is my sort of pseudo-code

Code: Select all

IAnimated* mesh = smgr->getMesh("level.3ds");
ISceneNode* node = smgr->addOctTreeSceneNode(mesh->getMesh(0))
ITriangleSelector *selector = smgr->addOctTreeTriangleSelector(mesh->getMesh(0), node);
node->setTriangleSelector(selector);
selector->drop();
(--set rotation of node here)

ISceneNode* player = smgr->addAnimatedMeshSceneNode( smgr->getMesh("another.3ds"));
aabbox3d<f32> box = player->getBoundingBox();
ISceneNodeAnimator *anim = smgr->createCollisionResponseAnimator(selector, player, box.MaxEdge - box.getCenter(), vector3df(0, 0, 0));
player->addAnimator(anim);
anim->drop();

Is there something obvious I missed? As the code isn't working

I might add that gravitation seems to work on player-node, so something is correct I guess.

It appears that you drop the triangle selector and then you try to add it to the collision response animator. This can't work because you have removed the triangle selector from memory therefore the collision response animator has nothing to use. So wait to drop the triangle selector until you do not need collision detection anymore.

I think that shouldn't matter. The example does it the way I do it and I guess that the scene-node is adding a reference to the selector so I can safely drop it after I added to the scene-node. And like I said in the last post, gravitation is working and I i take my affected node outside the map it drops like a stone, but it can still run through objects on the node where the selector is.
