So in my scene I have a laser beam, any time an NPC walks across this beam, I want a physics object to push him in a direction. However, this could be applied to one NPC or if ten hit at the exact same time, all should be pushed in the same direction. I've tried using "Add Force" with just a direction assigned, no object, but it doesn't seem to have any impact. Each of my NPCs has a rigid box and a character controller. What am I doing wrong?
