how to destroy objects by parts

when player collides object . That objects will be destroyed by parts

Hi there,

You will need those parts modeled individually. You have to create a Prefab, with all those parts joined together.

And then, when the player collides with the original object, you must Instantiate that prefab, in the position and rotation of the original one. Remember to destroy the original one.

That way, you will get at the moment of the collision, a new gameObject that will be able to be destroyed in parts.

Hope it helps.
