AABB movement

[en51nm]

Hello, I'm having some more problems with movement of my Mesh Node and AABB.

Here is a video of my problem.

I create the node like this:

Code: Select all

 
irr_node = smgr->addMeshSceneNode(smgr->getMesh("sphere.3ds")->getMesh(0));
 

Then I get my AABB inside my draw loop, and draw four edges:

Code: Select all

 
vector3d<f32> edges[8];
irr_node->getTransformedBoundingBox().getEdges(edges);
for(int i=0;i<8;i+=2)
{
        driver->draw3DLine(edges[i],edges[i+1],SColor(255,0,0,0));
}
 

The movement is done in exactly the same way as in tutorial 4

For some reason, my AABB doesn't move with the mesh properly (as shown in video), this causes problems with my AABB collision detection.

Interestingly, if I add another scene node in the same way, the first scene node moves the AABB of both of them but the second scene node and AABB both move in unison as they should do.

hi

if you set

Code: Select all

 irr_node->setDebugDataVisible(true);

you can see also the box. maybe different results?

I suppose the problem is that the you have the wrong transformation before the draw3DLine call. You might need a call like that first:

Code: Select all

 
 driver->setTransform(video::ETS_WORLD, core::matrix4());

Thanks CuteAlient, that worked like a treat =D

Having problems with collision detection now though, it works up until I try to rotate the objects.

EDIT: All working now. I have a question though. Is it possible to alter the position of a scene nodes rotation centre?
