If you have a "when ___, create clone" on an object, the growth is exponential.
What is the simplest or most elegant way to have one button press create only a single clone and not a single clone for each original + clone?
Is it unique ID's in stored in a list? Os it a list of objects itself? Is there a way to check if the block is already running on another object?
maybe like this?
That is basically what is going on. This is a student project:
The problem is that every clone is running this code too, so the growth is exponential. If I wait until the clone hits the edge of the screen and deletes then no problem ... but if I try to shoot 12 times quickly there are around 2^12 sprites or around 4,000 bullets on the screen

This is what I love about programming. So many different solutions!
Can I ask, why does the parent is a text work? I get the empty parent vs has a parent, but why use "is a text"? Isn't the parent a sprite/object? Is it stored as a text?
Also, I wish I could mark 2-3 solutions. There are always multiple solutions.
If you have a parent, the block reports the sprite. If you don't have a parent, it reports an empty string, which is what we use in general for "no result." If I were designing Snap! from the beginning (I'm bending over backward not to say "from scratch" which would be very ambiguous in this context) I'd use False as the no-result convention.
