Make rigidbody not affected by other rigidbodies, but still collide and have gravity

Hello!

I'm wanting to make a rigidbody that isn't affected by other rigidbodies (aka won't be pushed around by them but instead stay still and collide with them), but still have gravity and fall.

Sounds complex, and probably not possible... but just making sure there isn't an obvious trick I'm missing here.

The backstory for why I need this is that I'm having a mobile app where you can drag items around, but I don't want the other items to be pushed by the currently dragged item. However these non-dragged items still need to react to gravity.

 

I don't understand the case entirely, but the available tricks and techniques that seem related to me are:

• Kinematic bodies
• Ignore collisions (Physics.IgnoreCollision)
• Separate physics scenes (example)

Maybe you could achieve what you're looking for using a combination of these.

 

@Edy is spot on (as usual), if you want to flail around a rigidbody object and not have it wreck up the place make the rest of the level kinematic, if you still need something dynamic in the scene you could maybe give everything a huge mass and the dragged object Mathf.epsilon making it barley exert any force on collision, but it can affect stuff house of card style i believe.
