将 Rigidbody2D 设置为具有静态行为。
静态行为将停止 Rigidbody2D 对重力作出反应或施加力,包括与任意其他 Rigidbody2D 接触。
并且永远不应显式重定位这种类型的 Rigidbody2D。它设计为永不移动。
静态 Rigidbody2D 将只与动态 Rigidbody2D 刚体类型碰撞。Rigidbody2D.useFullKinematicContacts 设置为 true 时例外,在这种情况下,它将与任意 [[Kinematic]] 刚体类型碰撞。
当附加的 Collider2D 设置为触发器时,它将始终为附加到 [[Dynamic]] 或 [[Kinematic]] 刚体类型的任意 Collider2D 生成一个触发器。
另请参阅:Rigidbody2D.bodyType、Rigidbody2D.useFullKinematicContacts。
