Hello! Welcome to the forums. This is a pretty vague post since we don’t have any idea how your current implementation is setup. Is there anything you can show for your AI enemies so we can go off a bit more?
What I can give you for an idea to start right now though, is to have your enemy have an overlap sphere (or box if it’s preferable) and use the on overlap functionality to check for the player character type you have and then do your throw spear functionality.
You can then also have them stop throwing by using the On End Overlap Functionality as well. Hope this pushes you in the right direction.

this is how its currently set up, however it doesnt move to the player, it moves to the left of the enemy in the world.
ideally id like it to essentially launch at the player though
Hey @Spirits_Shade, Welcome to the forums!
If you have the spear be a seperate actor, that would make this even easier. You can use “Suggest Projectile Arc” and have it use that for launch velocity.
Here’s a tutorial for that from Matt Aspland!
