How to place a node under the mouse pointer?

[Serg Nechaeff]

Please help! I need to make my particle node to follow the mouse pointer. What is the best way to do that? In Blitz3D I could place a plane in front of the camera, calculate the coordinates of the collision with that plane using screen coordinates and thus taking these 3d coordinates. Will such a method work in Irrlischt? Maybe there is an easier way?

Get the collision manager from the scene manager (smgr->getCollisionManager()). Cast out a ray to get the line 3d line the mouse is currently over (cmgr->getRayFromScreenCoordinates(cursor->getPosition())). Then just determine how far along the ray you want to go (I suppose the same way you determined how far out to place your plane in Blitz3D).

Thanks a lot!

You mean, like in collision example?
