static var sleepVelocity : float

Description

The default linear velocity, below which objects start going to sleep (default 0.15). Must be positive.

See Rigidbody Sleeping for more information. This value can be overridden per rigidbody using Rigidbody.sleepVelocity.

This value is usually changed in Edit->Project Settings->Physics inspector instead of from scripts.

Physics.sleepVelocity = 0.1;
