ConeLight visual bug

Hi there!

I have encountered a visual bug with a ConeLight that matches a socket position + orientation. See video.

Bug Video

The code is pretty simple. The player holds a flashlight object (inherited from Game.Animatable) in his hand. This object draws the LightCone. The update looks like this:

Code:

bool FlashLight::update()

{

   C OrientP* handSlot  = Players[0].skel.getSlot("HandR");

   Matrix lightMat = Matrix().setPosDir(handSlot.pos, handSlot.perp, handSlot.dir, handSlot.cross());

   skel.clear().updateMatrix(lightMat).updateVelocities();

   return true;

}

And the draw:

Code:

uint FlashLight::drawPrepare()

{

   if(m_Enabled)

   {

      C OrientP* lightSlot = skel.getSlot("LightSlot");

      LightCone light(0, 0, 0, Vec(1, 1, 1), 0.015f, 0.1f);

      light.pyramid = PyramidM(0.45f, 12, lightSlot.pos, lightSlot.dir);

      light.falloff = 1.0f;

      light.add();     

   }

   return super.drawPrepare();

}

The hand is moved in the player class.

Any idea why this is happening?

Thanks for reporting! I'll take a look at this in the next few days. And will try to fix it quick

This could be related to LightCone.toScreenRect however codes look alright at a first glance. So I'll have to test it manually.

Hi,

I can't repro this problem, it works fine for me.
Would you mind submitting some sample EsenthelProject with the issue? (can be your original project or another small one)
You could send a link to me via email or private message.

Sure! I'll prepare something when I am home. Thank you!
