a quick test blend I made last night.
I suggested this method in another thread. Using collisions and ipo actuator you can setup your character lighting in a different way.
I’ve used vertex parenting to parent the lights to the actor. Then I setup a polygon to represent the area where the light setup should be more entense. When the actor and this polygon collide the ipo runs and the lighting changes.
To be honest I don’t understand why this file works the way it does. I found the setup just by randomly chosing different play methods for the ipos. For some reason a flipper and ping pong actuator got the job done.
