类名称：Body
方法名：setActive

Body.setActive介绍

[英]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.
[中]设置主体的活动状态。非活动物体不被模拟，不能碰撞或唤醒。如果您传递了true标志，则所有装置都将添加到宽阶段。如果您通过false标志，则所有固定装置将从宽相位中移除，所有触点将被销毁。固定装置和接头不受影响。可以继续在非活动实体上创建/销毁装置和关节。非活动实体上的装置隐式处于非活动状态，不会参与碰撞、光线投射或查询。连接到非活动实体的关节隐式处于非活动状态。非活动实体仍由世界对象拥有，并保留在实体列表中。
