Collision with different instances of the same object

Hello, I’m making a game about merging same level balls to make higher level ones. The problem is that all balls are the same object, and I can’t detect when they collide with eachother. Here’s the game project:

I did seen your message on discord i just forgot to reply to you but here is as good as there

Try repeat for each object
And / or distance between two object instead of collision check

I remember i saw it somewhere working i just don’t remember exactly how

Damn i think i just found it

This is discord link
