Collision Detection: .obj mesh vs. Q3 Bsp

[fitfool]

Hi, im sorry if this is a widly asked question but does anyone know of a tutorial which will show me how to implement collision detection with a mesh(.obj) versus a quake 3 map? thanks;

Try the collision tutorial you get with Irrlicht. It's also on the main website. If you need better collision get a physics engine (Newton, Ageia, etc.). The format of your meshes is irrelevent by the way, as long as you can load them into Irrlicht.

Ive taken a look at those, but i dont see a way that i can tell if it has collided with something. How can i tell if it has so i can do a explosion/stuff like that.
Thank's

I'm just an absolute beginner here, but I think if you look at how the material lighting changes with the fairy, that's how you get collision for an object other than the static geometry. It's not extremely accurate, so you'd have to use a physics engine if you wanted more accuracy.

In the tutorial, just replace

selector = smgr->createOctTreeTriangleSelector(

with

selector = smgr->createTriangleSelector(

Hope that works.

ok cool, i have the collision detection working, but i need to see were it hit the object its colliding with. Any help?

thanks

And this is how im doing it.

Selector = Globals::SceneMgr->createOctTreeTriangleSelector( Globals::Map->getMesh(0), Globals::MapNode, 128 );
Globals::MapNode->setTriangleSelector( Selector );

ISceneNodeAnimator *Collision = Globals::SceneMgr->createCollisionResponseAnimator( Selector,
RocketNode,
vector3df(25, 25, 25),
vector3df(0, 0, 0),
vector3df(0, 0, 0) );

RocketNode->addAnimator( Collision );
Collision->drop();
Selector->drop();
