the class Body method setActive.

/**
 * Set the active state of the body.
 * An inactive body is not simulated and cannot be collided with or woken up.
 * If you pass a flag of true, all fixtures will be added to the broad-phase.
 * If you pass a flag of false, all fixtures will be removed from the broad-phase and all contacts will be destroyed.
 * Fixtures and joints are otherwise unaffected.
 * You may continue to create/destroy fixtures and joints on inactive bodies.
 * Fixtures on an inactive body are implicitly inactive
 * and will not participate in collisions, ray-casts, or queries.
 * Joints connected to an inactive body are implicitly inactive.
 * An inactive body is still owned by a World object and remains in the body list.
 *
 * @param flag active flag
