Destroying objects

HEy i am making a mechanic for this game i am creating and i need to destroy a single instance of a object on screen and not all of them.

capx

In depth: When you hit space you create bubbles(Circles) and they rise up. What i want to do is destroy the bubble after t is created for a certain amount of time. If there are multiple of that said bubble on the screen i don't want all of them to be destroyed but only 1 at a time depending on how long they have been alive.

Create an instance variable "lifespawn" to your bubbles object.

Either set it to 0 and increment it by 1 every frame/tick until it reaches 120 for example (120 = 2 seconds since the app runs at 60 fps).

Or either set it to your max value, decrement it by 1 each frame and when it reaches 0 then you know you want to destroy that bubble.

In one case or another, make a condition Bubbles.lifespawn = End_Value

+ action Bubbles.destroy (this will pick only the bubbles which lifespawn reached their final value).

This is like the health mechanic in the Beginner's guide, page 6, private instances section

Thanks, i will ake a look at what you have said and linked. :)

Ok got it working. I was thinking how instance variables work wrong. Now that i kno how they work it will be a lot easier.
