**继承：** :ref:`Node2D<class_Node2D>` **<** :ref:`CanvasItem<class_CanvasItem>` **<** :ref:`Node<class_Node>` **<** :ref:`Object<class_Object>`
|
|
|

描述
|
|
----
|
|
|
|
A node that provides a :ref:`Shape2D<class_Shape2D>` to a :ref:`CollisionObject2D<class_CollisionObject2D>` parent and allows it to be edited. This can give a detection shape to an :ref:`Area2D<class_Area2D>` or turn a :ref:`PhysicsBody2D<class_PhysicsBody2D>` into a solid object.

碰撞形状的颜色，在编辑器中显示，勾选编辑器顶部的 **调试 > 显示碰撞形状** 时也会在运行项目时显示。
|
|
|
|
\ **注意：**\ 默认值为 :ref:`ProjectSettings.debug/shapes/collision/shape_color<class_ProjectSettings_property_debug/shapes/collision/shape_color>`\ 。这里记录的 ``Color(0, 0, 0, 0)`` 值是占位符，不是实际的默认调试颜色。

|
|
\ **注意：**\ 如果这个 **CollisionShape2D** 是 :ref:`Area2D<class_Area2D>` 节点的子节点，则这个属性无效。
