Here is a short 3min tutorial but very effective how to set up pawn sensing and then how the enemy character will move to you when they see you. In beat em up like your game i guess they should see you immidiatly, so make the pawn sensing range big enough. And then after they walk to you put your fighting code just after that and they will start fightning when they reach you.
Btw i see he is using unreal 4 and when you add the pawn sensing component you can click on it on your character on the left and on the right site in the details panel scroll down to “Event” then click “On see pawn”. Is the only diference if you cant find it like he do on his unreal 4 version the rest you could follow as it is and it should work.
