The Sleeping property of a PhysicsBody indicates whether the physics body is currently in a "sleeping" state. Physics bodies automatically enter this state after a period of inactivity to optimize performance. This property can be used to manually wake the body or force it into a sleeping state.
To check if a physics body is currently sleeping, simply access the Sleeping property. To wake a sleeping body, set this property to false. Conversely, to put a body to sleep, set it to true.
// Example of using the Sleeping property
PhysicsBody myPhysicsBody = new PhysicsBody();
// Check if the body is sleeping
bool isSleeping = myPhysicsBody.Sleeping;
// Wake the body up if it is sleeping
if (isSleeping)
{
myPhysicsBody.Sleeping = false;
}
// Put the body to sleep
myPhysicsBody.Sleeping = true;
