???Swinging Dynamic Light???

Post by Moebius »

Any way to make a dynamic light swing like a pendulum?

I have a 3D model light that hangs from the ceiling. I can make it oscillate and would like the light from it move as it moves.

My general impression from what I've tried is it can't be done.

Oh, is it a spot / cone light (DYNAMICLIGHT.LF_SPOT flag for A_AttachLight)? If so, assigning it to an object that is changing the pitch / angle values in a "pendulum way" and calling A_AttachLight with the updated pitch value each tick should do the trick.
