I need help with collider detection and physics

So, I need help with my project. Some dots that move around the map that must bounce when they are touching the walls (they are gameObjects I put). But they must not collide physically when they touch each other and yet they must detect the collision between each other. I have tried many things but I can’t find the solution to this, can you help me please? So, to recap, I need for the gameObects to detect when they collide without physically colliding. This may sound odd but I need it and I haven’t found any other way around it.

You can add a second collider to your objects, set to trigger. Set up layers so that the original colliders can’t hit objects on the same layer, but the triggers can. Then use OnTrigger methods to run code when they hit eachother.
