How do I make a rigidbody2d that doesn't do anything on collision?

The title says it all!

I have a 2d object that I need to gal from the sky!
Its currently using gravity.

I would like to make it so that when it hits something it is unaffected!

Like I want to manually do something when it collides with another object not have it fly off in some random direction.

How would I do this?
Or fake do this aka use kinematic + force somehow?

Figured it out!

If you need to this simply set the game object to a trigger

This can be done in the inspector window in unity

-Hope this helps!
