Collision to kill with projectile

Hi,i have a question about collision on UE4.
I try to kill the AI(BOI ATIRA) with the blueprint(TIRO) ,anybody help me?

way to general of a post my dude. this is one of those basic things that have been asked a million times and answered as many. do a quick search and you will find many tutorials on this.

now as for accomplishing what you ask its pretty simple: on begin overlap or hit → destroy actor. so to set this up go into your projectile (tiro) and create the on begin overlap event. next you need to define what actors to affect so we will use a cast, cast to (insert actor class here) for this ill assume a cast to character. make sure you connect the other actor pin from the event to the object in of the cast (blue to blue pins). next create a destroy actor node and connect exec and as character pins from the cast to the destroy actor. thats basically it for the scripting.

one other thing to note is that you need to make sure the projectile can overlap the character. select the projectiles sphere collision and in the details panel just set its collision preset to overlap all.
