can you explain your issue a bit more? “I can not seem to implement the detection for more enemies?” do you mean enemies of different classes? if thats the cast then that wont be easy with your current setup, i would suggest you make use of the built in damage system in the engine. look into the apply damage and the event any damage nodes. using those two will make it so you can damage any actor without needing to cast to them. it will require you to setup how the damage is handled on the other end via the event any damage though. this last point can be mitigated however if you use inheritance to have all your characters inherit from a common parent.
