The StartAsleep property of the Rigidbody class determines whether the rigidbody should start in a sleeping state when the simulation begins. When set to true, the rigidbody will not participate in the physics simulation until it is woken up by an external force or interaction. This can be useful for optimizing performance by preventing unnecessary calculations for objects that are initially at rest.
To use the StartAsleep property, simply set it to true or false depending on whether you want the rigidbody to start asleep or awake. This property should be configured before the physics simulation starts, typically during the initialization of the object.
// Example of setting the StartAsleep property Rigidbody myRigidbody = new Rigidbody(); myRigidbody.StartAsleep = true; // The rigidbody will start asleep // To wake up the rigidbody later, you might apply a force or interact with it myRigidbody.ApplyForce(new Vector3(0, 10, 0)); // This will wake up the rigidbody
