clone object in collision not work

hi I wanted to know can you help me to create this action, for example I created 5 clone objects, how can I use clone objects in collision event, because collision only makes one clone object works 4 others don’t work in 2d.

All your clone object have a rigibody and a collider ?

Normaly if it’s the case you just have to attach a script with the method void OnCollisionEnter(Collision collision)

You can have an example here : Unity Documentation OnCollisionEnter
