Easy way to remove all velocity

Hey guys,

a, hopefully, short and easy question this time. Ive been going thought the documentation on Rigidbody but I cannot seem to find an easy way to remove all velocity on a gameobject.

I've tried, of course, setting rigidbody.velocity to zero. This just seems to add zero to the current velocity though.

What I want is to respawn an object, which works, but I want all old velocity removed, how would I do this easily?

Edit for future reference:

Using rigidbody.velocity = Vector3.zero; does reset the velocity, but remember to also use rigidbody.angularVelocity = Vector3.zero to remove the spin.

`rigidbody.velocity=Vector3.zero` really does set automatic "physics" speed to nothing.

Something else must moving you. Maybe your script, for example, sets `rigidbody.velocity=MySpd;` each frame. So, of course, reset `MySpd`.

By Respawn, I assume you mean "teleport off left edge and pretend I'm a new car coming on"? If you are Instantiating (what I think of a a spawn,) there is no old velocity. It starts with the same stats as the prefab, which is always 0 for velocity.

You are right. When this object goes out of bounds I set it's transform to a 'respawnposition'. I've tried setting velocity to zero and I'm not manipulating it through script elsewhere, but I'll try it again. o.O maybe I did something wrong. Thanks for the help.

I think I figured it out. When I reset my object's transform and set it's velocity to zero it maintains it's current spin, causing it to move upon 'respawn'. Thanks for all the help.

You could "switch physics off": 

rigidbody.isKinematic = true;

Thanks I'll try this. I was hoping for a solution that could be passed in one command from an external script. Because now I'll have to turn kinematic off in the next frame I guess?
