Lights are cameras?

[Guppy]

While solving having only one camera shared between c++ and lua I came across something strange - all lights seem to be registered as cameras as well. Now I suspect that this has "something" to do with the deferred rendering, I was just hoping somebody could shed some light on what that "something" is

Lights render shadowmaps, which use a lot of the same code as normal rendering. So yes, lights are cameras.

If you want to know the amount of lights or camera's you can make use of these:

 

const int Object::CameraClass = 3;
const int Object::DirectionalLightClass=4;
const int Object::SpotLightClass=5;
const int Object::PointLightClass=6;

Yeah it was news to me as well - guess I never looked closely at the Command Reference page that shows the class hierarchy. And with the new changes to Entity:GetCulled(), you have the starting point for a game like Thief where it indicates if the player is in shadows or light.

You mean like MexSource was looking for?
