Problem on my RTS project

Hello i am new on UE and i am currently using UE4. I started a new blanck projet and add fps, tps, topdow and some other asset from the market place. i have a BP_Character and two instance from it BP_Shogun and BP_Opnent. After adding a pawn seesing component in my BP_Opent class i tried using the function on see pawn to print a hello when it see an objet from the BP_Shogun class. I added them to the level but it didn’t work. Can you help me identify the problem ?
