Collision- Triangle Selector, Node issue

[Earl]

Still trying to get collision to go in my basic program.
I'm getting pretty close to making this work I think, haven't had much time to do work on it due to school...
The collision seems to be nearly set up, but I can't get past this error.

"No matching function to call for irr::scene::ISceneManager::createOctTreeTriangleSelector(irr::scene::IAnimatedMeshSceneNode*&, int)'

I'm trying to use an OctTreeTriangleSelector as in the examples, but my my model is a .obj and I can't seem to figure out what's up. I load the model using IAnimatedMesh and it has an AnimatedMeshSceneNode, which I guess match up right. I kinda know from reading that the OctTree node is supposed to be with the OctTree selector... Is there a selector for animated mesh nodes? Or is there a way to make an octtree node for my .obj? I'm totally lost here.

did you use addOctTreeSceneNode() for creating the node ???

Uh, that is because there is no function named createOctTreeTriangleSelector() that takes the parameters you are passing it... Have a look at the function signature in the docs. Notice that the method takes an IMesh* as the first parameter, not an IAnimatedMesh* or an IAnimatedMeshSceneNode*. You need to pass an IMesh*, or something convertable to an IMesh*, as the first parameter to createOctTreeTriangleSelector(). The collision example shows how to do exactly what you are trying...

Thanks man My headache is over...
I ended up using a plain triangle selector instead of the OctTree selector. I guess my next thing is to find out what formats can be loaded with IMesh* so I can use the OctTrees, as my areas are going to be large and detailed.
Ever so slowly getting the hang of this...
Thanks again.
