How to set the difference between 2 or more copies of the same object?

I'm sure this problem was discussed somewhere in the internet before.

I have an event, that every time my player collides with the active object, I subtract 1 from his maximum of 100 HP and I have multiple copies of the same object in the scene. When the HP of the object reaches zero I destroy the object.

So, how can I stop the disappearing of all objects when one HP reaches 0?

I have a simple event for this: IF HP of Active = 0 then Destroy Active. I think I don't have a selection here, so it destroys every single instance of the Active.

How should I manage to do this selection?

Thank you!

balazstasi - as long as your condition is using the active object's alterable value for the HP, you should be OK with that Destroy Active event, it will select the active which has HP=0
HOWEVER - if you've done it as a general comparison of two values and used the active's HP as one value and zero as the other, then it won't do the selection before destroying.
Another possibility is that you're subtracting 1 from ALL the actives in your player collision event (hard to tell without seeing your mfa file - upload a small example if you can)

Gosh, I was so dumb.

Yes, you were right, I didn't have a correct selection at the collision events.

Now it's all fine, working good.

Tanks, AyreGuitar!

You're welcome! Glad you fixed it (we've all been there and done something similar!)

For more complex actions, you can use a "For Each Loop", to set a unique ID to each instance of an object too, or use the fixed ID of each instance.
