How can I destroy child object when parent object is destroyed?

Hey, for my game I'm using 2 active objects for each enemy. A parent object for the enemy and its values, and a child object for its animation.

Now the issue I have with this is that I can't figure out how to destroy the child object when the parent object's health reaches 0. I mean, I can do 'Health of Parent = 0 -> Destroy Parent, Destroy Child', but then that destroys all versions of the child object (including the ones whose parent object still lives). I know that I need to add a condition that only applies to the specific enemy but I don't know how I could do this. Does anyone have an idea?

I'm not sure how fixed value is supposed to help here. If I understand correctly, a fixed value is a unique value that every object has. How does that allow me to destroy a specific object when an other specific object is destroyed?

I also tried using spread value but that did not seem to work. Maybe I did it wrong. What I did was:

Always
- Parent: Spread value 1 in Alterable Value D
- Child: Spread value 1 in Alterable Value A

Alterable Value E of Child = Alterable Value D
Health of Parent = 0
- Destroy Child
- Destroy Parent

However, this seems to only destroy the parent objects.

Well, I appreciate you trying to help me but that example simply doesn't have anything to do with what I need help with. I've got alterable values and healthbars working fine already. Maybe I wasn't clear, let me try to explain again.

In my game, an enemy gets created every time the player takes X amount of steps.
An enemy consists of 3 objects;
1. Active object - Position, Alterable values, behavior etc (Parent object)
2. Counter - Healthbar (Child object that follows the Parent object)
3. Active object - Appearance and animation (Child object that follows the Parent object)
When the Health (alterable value) of an enemy reaches 0, it is destroyed.
When the value of a healthbar reaches 0, it is destroyed.

However, how can I make it so the other active object (child object) is destroyed when its parent object is destroyed?

Thank you all very much for the help. However, I've been trying for 2 days now and still haven't gotten it to work correctly.

I made this (extremely) stripped down version of my game. Could someone please look at the mfa and tell me what I'm doing wrong here?

Thanks for the tips. Though the issue is not resolved in the mfa that you attached? The child objects aren't getting destroyed, they're just getting moved to an other parent. They only get destroyed when the last parent is destroyed.

However, keeping in mind to destroy the child before the parent, I deleted everything from my previous attempt and started over. Now I've got this:

Every 5 seconds
- Create Parent
- Create Child
- Parent: Set Alterable Value A (Health) to 100
- Parent: Set Alterable Value B (ChildID) to Fixed value of Child

Alterable Value A (ChildDead) of Child = 0
- Set position at (0,0) from Parent

Health of Parent <= 0
Fixed value of Child = ChildID of Parent
- Child: Set ChildDead to 1

Health of Parent <= 0
ChildDead of Child = 1
- Destroy Child
- Destroy Parent

Now this should make the Child follow the Parent until the Parent's health is 0, then destroy the Child, and then destroy the Parent. This works fine when enemies are killed one by one, however when multiple enemies die at the same time, only one of the Child objects is destroyed, and the other ones are either teleported to an other Parent, or to 0,0 (until a new parent appears where they can get teleported to). This should not happen because the Child objects should only follow their Parent when their alterable value ChildDead is set to 0. This means that only one of the Child object's ChildDead value is being set to 1, while the others stay on 0. How can I fix this? Tried using loops but that didn't work, but maybe I did it wrong.

Hey, thanks. Any progress on this?
I have been trying a lot of different things but still haven't been able to get it to work.
