How do I make all enemies take damage from 1 event?

I don't really know how to say this right, but in my game I have multiple enemies, and the current way damage is dealt to them is by each weapon having its own event block that deals damage to that enemy, and I have to create a new event for every enemy that a weapon/projectile can hit, and it very quickly clutters up the event sheet. Is there a way to make it where all I only need 1 event for something to do damage to different enemies?

You want to use families.

If you have the paid version you'll want to use families like oosy suggested.

Otherwise you will need an event for each type of enemy. I suggest creating a Group for damage enemies. Then you can throw all your gross code into there and minimize the group so it takes up next to no room. Every time you add a new enemy you will have to pop open your damage enemies group and add the new enemy.

So I tried using families, but came across an issue.

All my enemies have different amounts of health, and if I use families, they would all have to share the same health variable, which I don't want to do.

What? No. Every instance of every object in a family can have their own value for the variable, even if the variable is the family's variable.

I get that, but that's not what I mean.

Certain enemies have different max healths, Ex: One has 13 and the other has 11, and from what I can tell there is no way to use families in a way that makes it to where they can keep their different max healths in a convenient way. I could make different families for different health classes of enemies, but I don't have a large enough amount of enemies for that to be helpful, and I don't have a small enough amount for each one to have its own event and it still be easily manageable.

They can still have individual variables in addition to the family variables.

Sure you can, you just need to make sure you call the specific instance you want with UID.

On the time of collision I grab the UID of the auto attack as well as the Enemy I need to target. My enemies all have different health amounts.
