Dynamic light affect player only?

by Randy Condon · in Torque Game Engine · 09/02/2006 (1:23 pm) · 3 replies

Is there a straightforward way for a dynamic light to only affect specific .dts objects (like a player object)?

It seems the 'lightGroup/EffectsDTSObjects=false' behavior is the ticket, but will that work for non-static, shapebase derived objects (player, vehicle, etc.)?

Thanks in advance.

Okay, not the ticket.

EffectsDTSObjects seems to only effect static Lights.

Implemented a test with setting the score on installGLLights to zero for Point types, depending on a new var passed to ignore dynamic lights or not. Managed to get only DTS objects lit that were designated to do so. (But didn't work for terrain, not that I have much terrain).

Probably not the general solution, but might work for what I'm working on. I'll give it a think overnight and have a look tomorrow. (Still testing and exploring, hence this approach).

The goal is to get an attached dynamic light that only lights the the main character and his vehicle. (No shadows)

Hmm, the best way to do that might be to give the vehicle a LightInfo object that defines its light and make sure the light is added to the light manager in sgSceneObject::installLights (sgSceneObject.cc line 174), see sgSceneObject::installLightsAdvanced for an example of how this is done (when it adds the sgLightIds list lights). Make sure to remove the light in sgSceneObject::uninstallLights.

This will make the light unique to the vehicle - you'll need to find a way to light the player too (copy the light when mounted, or check to see what it's mounted to and pull its light).

Thanks John.

Works, just what I was looking for.
Again, thanks for those pointers.
