I don’t know how to change my actors so that they will simulate physics. If I set the mesh as the root then it screws up everything regarding the actor (such as position and the ability to resize it). I followed this guy’s tutorial (Let's Make: An Interaction System: Part 1 - YouTube) on creating both an interaction system and a parent blueprint. His interaction system is exactly what I need but I ended up running into two problems: Interaction still occurs through other actors and, since the root component is an icon, I can’t seem to toggle physics on for the whole actor.
