PhysicsServer2D
===============
**继承：** :ref:`Object<class_Object>`
**派生：** :ref:`PhysicsServer2DExtension<class_PhysicsServer2DExtension>`
用于访问低阶 2D 物理的服务器接口。
.. rst-class:: classref-introduction-group
描述
----
PhysicsServer2D 是负责所有 2D 物理的服务器。它可以直接创建和操作所有物理对象：
- *Space（空间）*\ 是用于物理仿真的自包含世界。它包含实体、区域和关节。可以对其状态进行查询，获取碰撞和相交信息，并且可以修改部分仿真参数。
- *Shape（形状）*\ 是圆形、矩形、胶囊形、多边形等几何形状。加入到实体/区域中就可以用来进行碰撞检测，还可以带有相对于实体/区域原点的额外变换。实体/区域中可以添加多个（变换后的）形状，并且可以使用不同的局部变换将单个形状多次添加到实体/区域中。
- *Body（实体）*\ 是物理对象，可以处于静态、运动学或刚性模式。可以对其状态进行查询和更新（例如位置、速度等）。可以设置力的集成回调，自定义实体的物理特性。
- *Area（区域）*\ 是空间中的区块，可用于检测进入和离开它的实体和区域。可以设置实体的监视回调，报告进入/离开的实体形状，同样可以设置区域的监视回调。通过设置区域参数，可以在区域内覆盖重力和阻尼。
- *Joint（关节）*\ 是两个实体之间或一个实体相对于某个点的约束。可以调整关节偏置和弹簧关节的放松长度等参数。
\ **PhysicsServer2D** 中的物理对象可以独立创建和操作；不必将它们绑定到场景树中的节点。
\ **注意：**\ 所有 2D 物理节点都在内部使用这个物理服务器。将物理节点添加到场景树，就会导致在物理服务器中创建相应的物理对象。刚体节点会注册回调，该回调会（在每次物理更新时）使用物理服务器中相应实体对象的变换更新该节点的变换。区域节点会注册回调，用来通知区域节点与物理服务器中相应区域对象的重叠。射线投射节点会查询物理服务器中相关空间的直接状态。

设置定义形状配置的形状数据。要传递的 ``data`` 取决于形状的类型（参见 :ref:`shape_get_type()<class_PhysicsServer2D_method_shape_get_type>`\ ）：
- :ref:`SHAPE_WORLD_BOUNDARY<class_PhysicsServer2D_constant_SHAPE_WORLD_BOUNDARY>`\ ：长度为 2 的数组，包含 :ref:`Vector2<class_Vector2>` 类型的 ``normal`` 方向和 :ref:`float<class_float>` 类型的距离 ``d``\ ，
- :ref:`SHAPE_SEPARATION_RAY<class_PhysicsServer2D_constant_SHAPE_SEPARATION_RAY>`\ ：字典，包含键 ``length`` 和 :ref:`float<class_float>` 值、以及键 ``slide_on_slope`` 和 :ref:`bool<class_bool>` 值，
- :ref:`SHAPE_SEGMENT<class_PhysicsServer2D_constant_SHAPE_SEGMENT>`\ ：\ :ref:`Rect2<class_Rect2>` 类型的 ``rect``\ ，以 ``rect.position`` 表示线段中的第一个点，并以 ``rect.size`` 表示线段中的第二个点，
- :ref:`SHAPE_CIRCLE<class_PhysicsServer2D_constant_SHAPE_CIRCLE>`\ ：\ :ref:`float<class_float>` 类型的 ``radius``\ ，
- :ref:`SHAPE_RECTANGLE<class_PhysicsServer2D_constant_SHAPE_RECTANGLE>`\ ：\ :ref:`Vector2<class_Vector2>` 类型的 ``half_extents``\ ，
- :ref:`SHAPE_CAPSULE<class_PhysicsServer2D_constant_SHAPE_CAPSULE>`\ ：长度为 2 的数组（或一个 :ref:`Vector2<class_Vector2>`\ ），包含一个 :ref:`float<class_float>` 类型的 ``height`` 和一个 :ref:`float<class_float>` 类型的 ``radius``\ ，
- :ref:`SHAPE_CONVEX_POLYGON<class_PhysicsServer2D_constant_SHAPE_CONVEX_POLYGON>`\ ：按逆时针顺序定义凸多边形的点的 :ref:`PackedVector2Array<class_PackedVector2Array>`\ （在内部使用由连续点形成的每个线段的顺时针向外法线计算）；或一个长度可被 4 整除的 :ref:`PackedFloat32Array<class_PackedFloat32Array>`\ ，以便每个 4 元组的 :ref:`float<class_float>` 包含一个点的坐标，后跟一个向量的坐标表示，该向量是当前点和下一个点之间的线段的顺时针向外法向量，
- :ref:`SHAPE_CONCAVE_POLYGON<class_PhysicsServer2D_constant_SHAPE_CONCAVE_POLYGON>`\ ：长度可被 2 整除的 :ref:`PackedVector2Array<class_PackedVector2Array>`\ （每对点形成一个线段）。
\ **警告：**\ 在 :ref:`SHAPE_CONVEX_POLYGON<class_PhysicsServer2D_constant_SHAPE_CONVEX_POLYGON>` 的情况下，该方法不检查提供的点是否能够形成凸多边形（与 :ref:`CollisionPolygon2D.polygon<class_CollisionPolygon2D_property_polygon>` 属性不同）。
