[SOLVED]Pick instance overlapping a sprite

Hi, I want my game to destroy the instance of my Ball-Sprite that is overlapping a sprite without destroying the other instances of the Ball-Sprite, how can i do that ?

I try with "pick instance overlapping point", but a 1x1 point is too small (and too short in terms of time in-game) for this, I really need a bigger area.

I also wonder how to give a name/a value to a specific instance, I can't find any actions to modify/pick instance

Hi see if this helps. Click on a ball to assign a value to it.

Ok thanks, actually I just didn't understand why here it destroys only the ball that hit the sprite, while in a condition with keyboard pressed --> destroy ball , it destroys all the balls. Anyway, you solved my problem, thank you very much ^^

Because if you just do 'on keyboard pressed', you're not picking any objects. Actions work on picked objects. If you don't pick any specifically in an event then all of the object type are picked. So in the case of 'key pressed' the condition doesn't pick any balls so they are all picked by default, and you get all the balls destroyed, whereas in mine I've picked the one touched/clicked on.
