How do I destroy oldest object

I have turret firing projectiles and I want to destroy oldest projectile if X amount on screen.

I started with an array but couldn't get it to destroy anything. So I searched the forum for help and found this example, but still cant get it to destroy my projectiles. The array seams to work in the debugger If I remove pick instance with UID array.at(number).

Anyone have some idea how to solve this?

Haven't tested the other example with instance variable yet. Which one is best for performance?

Thanks

The simplest mechanism is to use the Fade behaviour, unless I misunderstand your requirement.

if projectile.count > X

pick nth(0) instance ---------destroy

that do it?

if projectile.count > X

pick nth(0) instance ---------destroy

that do it?

Works great, thanks

And thanks to blackhornet too.

But I still don't understand why I couldn't get the array to delete my projectiles.

if projectile.count > X

pick nth(0) instance ---------destroy

that do it?

That's a necroposting for sure, but i searched forums for my trouble and your reply worked just fine !

Just wanted to say "thank you" )
