Beam scenenode

Hi

Just checked the code of the Beam scene node, and I noticed there's the bounding box "Box" member object, which is not being initialized anywhere in the code provided.

Should be initialized inside the setLine method, I pressume?

I suspect if that's the case, it's been working for most people because it's being initialised with random values, probably generating a quite large bounding box.

Any example or version without textures (just solid/alpha color)?

If you're having trouble with the beam disappearing it's because the backspace culling is incorrectly removing it.


The bounding box is incorrectly set so irrlicht thinks the beam is behind the camera. To fix this change Saudi's solution thusly:

Code: Select all

       void CBeamNode::setLine(core::vector3df start, core::vector3df end, f32 thickness) 
        { 
            m_start = start; 
            m_end = end; 
            m_thickness = thickness; 
			Box.addInternalPoint (start);
			Box.addInternalPoint (end);
        }

hi i'm pretty new to irrlicht and i'm trying to use this code in an FPS game and i'm not getting any results.
i'm trying to use this as a laser beam for a gun.

i have tried changing the beam scale to make sure that its visible.
but so far i have not gotten anything to display on screen.
