描述
|
|
----
|
|
|
|
A node that provides a polygon shape to a :ref:`CollisionObject2D<class_CollisionObject2D>` parent and allows it to be edited. The polygon can be concave or convex. This can give a detection shape to an :ref:`Area2D<class_Area2D>`, turn a :ref:`PhysicsBody2D<class_PhysicsBody2D>` into a solid object, or give a hollow shape to a :ref:`StaticBody2D<class_StaticBody2D>`.
|
|
|
|
\ **Warning:** A non-uniformly scaled **CollisionPolygon2D** will likely not behave as expected. Make sure to keep its scale the same on all axes and adjust its polygon instead.

碰撞包含多边形及其内部区域。在这个模式下，该节点的效果与使用若干 :ref:`ConvexPolygonShape2D<class_ConvexPolygonShape2D>` 节点相同，其中的每个节点都包含该多边形凸分解后的凸形状（但不会有使用多个节点的负担）。

碰撞仅包含多边形的边缘。在这个模式下，该节点的效果与单个由若干线段组成的 :ref:`ConcavePolygonShape2D<class_ConcavePolygonShape2D>` 相同，其中（第一条以后的）每条线段都从上一条的终点开始，最后一条线段在第一条的起点结束（构成闭合但中空的多边形）。

\ **注意：**\ 如果这个 **CollisionPolygon2D** 是 :ref:`Area2D<class_Area2D>` 节点的子节点，则这个属性无效。
