Okay, there’s a lot to unpack.
So, for now, do NOT use the Paragon.
Create a copy of the BP_ThirdPersonCharacter and name it “BP_ThirdPersonCharacter_Agressor” or whatever you’d like.
Apply the DEFAULT AnimBP to BOTH blueprint characters.
Use the simplified code, and input BOTH BP_ThirdPersonCharacter and BP_ThirdPersonCharacter_Agressor into your scene.
I know for a fact that if you input the code correctly it will work with them. The Paragon characters may have background code that is interfering, but I cannot be certain at the moment.
(I wondered if the state machine was necessary, myself… but I’m actually unsure.)
