I'm trying to detect a possible collision between objects that could be stationary or moving in any direction (angle). 1. I want the object to be notified when a particle/object is inbound for collision. Essentially, I want to introduce AI where the object will take action when it is shot at or an enemy is approaching. 2. Another use-case is for scanning. I'd like an entity to be able to spot its enemies and get info like distance, velocity, type, etc. I've read through the documentation, examples, posts on the forum and searched online, but I've clearly missed something. Does anyone know a way to accomplish the above? Thanks!
