Are there only 4 attributes in Rigid Body 2D?

Hi All,
There are Mass, Friction, Angular Friction, Gravity in my Unity Rigid Body 2D. But I also need a Linear Drag and others in Rigid Body 2D. Is it a version problem or other kind of problem?
Thanks

 

There was never a version of Unity that had those 4 things. (Specifically, friction is part of a physics material, not a rigidbody, and there's no angular friction anywhere.) You can see in the docs what Rigidbody2D has.

Unity uses slightly different terminology to the official Box2D naming of some things. This will cause some confusion if you're coming from a pure Box2D environment, or any other 2D use of physics, where naming might be different, also.

You'll have to go through and read the docs and do a mental translation of terms from whatever you're used to thinking of as names to what it is in Unity.

 

eg.

Angular Friction == Angular Drag in Unity.

Linear Drag is there, built into RigidBody2D

But you can also add a world based joint for increased control over this, in ways that aren't linear. Which is super cool for slowing things down.

This is what you should be seeing in the Inspector.
