A Nasty Crash

[Munku]

This is what I am trying to do: get the *exact* coords from mouse to screen on a button click.

This is the code I am using:

Code: Select all

    vector3df target,location;
     triangle3df tri;
     line3d<f32> ray;
     ITriangleSelector *tSelector;
     ISceneCollisionManager *colMgr = smgr->getSceneCollisionManager();
     position2d<s32> cPos;
     ICameraSceneNode *cam;
     
   if (event.isLeftMouseDown() == true)
   {
     cam = smgr->getActiveCamera();
     cPos = rwnd->getCursorControl()->getPosition();
     ray = colMgr->getRayFromScreenCoordinates(cPos,cam);
     colMgr->getCollisionPoint(ray,tSelector,target,tri);      
   }

Alright, when the program executes the getCollisionPoint it crashes with a seg fault. Anyone see a problem with this code? I've checked and the colMgr, Ray, cam and cPos are not 0/NULL.

You aren't saving the return value from getCollisionPoint() ?

I would be, but unfortunatly, it crashes on GetCollisionPoint. I omitted the return to try and get it to work. I know I need it

How are you creating the triangle selector?

doesn't look like he is from that code.

By the Gods I am stupid

Thanks, I thought I was forgetting something important .
