How do I substract a circle from a sprite?

Dear all!

I am looking for a solution, where I can substract small circles from a bigger sized sprite at the exact position where the collision happened?

Just to put it in context: like a gun would shoot at a big square sprite, and I would like to substract small circles where the bullets hit the square.

Thank you in advance!

Hi, I used to do this in a game, here's a simple example.

Maybe you'll find it useful.

Great! Thank you very much!
