Do some damage to enemys?

I want to hurt my enemys . i already made punch animation for my character so when i press left button he plays punch animation but now i want it to interact with my enemy ai so i want him to recevie damage when my character punch him so i made an animation for enemy ai when he recevies punch but now i need help in applying that to my enemy ai and make him die after getting 7 or 8 hits and play that animation that i created while receving damage . it would be better to do it without health bar so what are things that i need to do now?

Short version:

Create a variable containing the HP. Add collision to your fist and characters (if it doesn’t exist already) and on hit apply damage to the AI character.

You should probably watch some videos on this topic.

This is a good one for example:

But that video you gave a link is differnt because he is doing it with cube but i have a character as enemy ai so there are lots of differnce

i found a video where he does it with real enemy ai instead of cube but he uses blueprint that already created in his previous video here is video UE4 Blueprint Tutorial 10 - AI Melee Boss (2/4) - YouTube. its name is “UE4 Blueprint Tutorial 10 - AI Melee Boss (2/4)” and the uploader name is moize opel

…the difference is the collision setup. Besides that it’s pretty much the same.
