用於存取低階 2D 物理的伺服器介面。

說明
----
PhysicsServer2D 是負責所有 2D 物理的伺服器。它可以直接建立和操作所有物理對象：
- *Space（空間）*\ 是用於物理模擬的自包含世界。它包含實體、區域和關節。可以對其狀態進行查詢，獲取碰撞和相交資訊，並且可以修改部分模擬參數。
- *Shape（形狀）*\ 是圓形、矩形、膠囊形、多邊形等幾何形狀。加入到實體/區域中就可以用來進行碰撞偵測，還可以帶有相對於實體/區域原點的額外變換。實體/區域中可以新增多個（變換後的）形狀，同一個形狀可以使用不同的局部變換新增到實體/區域中。
- *Body（實體）*\ 是物理物件，可以處於靜態、運動學或剛性模式。可以對其狀態進行查詢和更新（例如位置、速度等）。可以設定力的集成回呼函式，自訂實體的物理特性。
- *Area（區域）*\ 是空間中的區塊，可用於偵測進入和離開它的實體和區域。可以設定實體的監視回呼函式，報告進入/離開的實體形狀，同樣可以設定區域的監視回呼函式。通過設定區域參數，可以在區域內覆蓋重力和阻尼。
- *Joint（關節）*\ 是兩個實體之間或一個實體相對於某個點的約束。可以調整關節偏置和彈簧關節的放鬆長度等參數。
\ **PhysicsServer2D** 中的物理物件可以獨立建立和操作；不必將它們綁定到場景樹中的節點。
\ **注意：**\ 所有 2D 物理節點都在內部使用這個物理伺服器。將物理節點新增到場景樹，就會導致在物理伺服器中建立相應的物理物件。剛體節點會註冊回呼函式，該回呼函式會（在每次物理更新時）使用物理伺服器中相應實體物件的變換更新該節點的變換。區域節點會註冊回呼函式，用來通知區域節點與物理伺服器中相應區域物件的重疊。射線投射節點會查詢物理伺服器中相關空間的直接狀態。

Sets the body's custom force integration callback function to ``callable``. Use an empty :ref:`Callable<class_Callable>` (``Callable()``) to clear the custom callback.
The function ``callable`` will be called every physics tick, before the standard force integration (see :ref:`body_set_omit_force_integration()<class_PhysicsServer2D_method_body_set_omit_force_integration>`). It can be used for example to update the body's linear and angular velocity based on contact with other bodies.
If ``userdata`` is not ``null``, the function ``callable`` must take the following two parameters:
1. ``state``: a :ref:`PhysicsDirectBodyState2D<class_PhysicsDirectBodyState2D>` used to retrieve and modify the body's state,
2. ``userdata``: a :ref:`Variant<class_Variant>`; its value will be the ``userdata`` passed into this method.

Sets the shape data that defines the configuration of the shape. The ``data`` to be passed depends on the shape's type (see :ref:`shape_get_type()<class_PhysicsServer2D_method_shape_get_type>`):
- :ref:`SHAPE_WORLD_BOUNDARY<class_PhysicsServer2D_constant_SHAPE_WORLD_BOUNDARY>`: an array of length two containing a :ref:`Vector2<class_Vector2>` ``normal`` direction and a :ref:`float<class_float>` distance ``d``,
- :ref:`SHAPE_SEPARATION_RAY<class_PhysicsServer2D_constant_SHAPE_SEPARATION_RAY>`: a dictionary containing the key ``length`` with a :ref:`float<class_float>` value and the key ``slide_on_slope`` with a :ref:`bool<class_bool>` value,
- :ref:`SHAPE_SEGMENT<class_PhysicsServer2D_constant_SHAPE_SEGMENT>`: a :ref:`Rect2<class_Rect2>` ``rect`` containing the first point of the segment in ``rect.position`` and the second point of the segment in ``rect.size``,
- :ref:`SHAPE_CIRCLE<class_PhysicsServer2D_constant_SHAPE_CIRCLE>`: a :ref:`float<class_float>` ``radius``,
- :ref:`SHAPE_RECTANGLE<class_PhysicsServer2D_constant_SHAPE_RECTANGLE>`: a :ref:`Vector2<class_Vector2>` ``half_extents``,
- :ref:`SHAPE_CAPSULE<class_PhysicsServer2D_constant_SHAPE_CAPSULE>`: an array of length two (or a :ref:`Vector2<class_Vector2>`) containing a :ref:`float<class_float>` ``height`` and a :ref:`float<class_float>` ``radius``,
- :ref:`SHAPE_CONVEX_POLYGON<class_PhysicsServer2D_constant_SHAPE_CONVEX_POLYGON>`: either a :ref:`PackedVector2Array<class_PackedVector2Array>` of points defining a convex polygon in counterclockwise order (the clockwise outward normal of each segment formed by consecutive points is calculated internally), or a :ref:`PackedFloat32Array<class_PackedFloat32Array>` of length divisible by four so that every 4-tuple of :ref:`float<class_float>`\ s contains the coordinates of a point followed by the coordinates of the clockwise outward normal vector to the segment between the current point and the next point,
- :ref:`SHAPE_CONCAVE_POLYGON<class_PhysicsServer2D_constant_SHAPE_CONCAVE_POLYGON>`: a :ref:`PackedVector2Array<class_PackedVector2Array>` of length divisible by two (each pair of points forms one segment).
\ **Warning:** In the case of :ref:`SHAPE_CONVEX_POLYGON<class_PhysicsServer2D_constant_SHAPE_CONVEX_POLYGON>`, this method does not check if the points supplied actually form a convex polygon (unlike the :ref:`CollisionPolygon2D.polygon<class_CollisionPolygon2D_property_polygon>` property).
