切换到手册

描述

用于 2D 物理的碰撞体，表示由其顶点定义的任意一组相连边缘（线）。

另请参阅：BoxCollider2D、CircleCollider2D、PolygonCollider2D。

变量

adjacentEndPointDefines the position of a virtual point adjacent to the end point of the EdgeCollider2D.
adjacentStartPointDefines the position of a virtual point adjacent to the start point of the EdgeCollider2D.
edgeCount获取边缘的数量。
edgeRadius控制该碰撞体创建的所有边缘的半径。
pointCount获取顶点的数量。
points获取或设置定义多条连续边缘的顶点。
useAdjacentEndPointSet this to true to use the adjacentEndPoint to form the collision normal that is used to calculate the collision response when a collision occurs at the Edge Collider's end point. Set this to false to not use the adjacentEndPoint, and the collision normal becomes the direction of motion of the collision.
useAdjacentStartPointSet this to true to use the adjacentStartPoint to form the collision normal that is used to calculate the collision response when a collision occurs at the Edge Collider's start point. Set this to false to not use the adjacentStartPoint, and the collision normal becomes the direction of motion of the collision.

公共函数

GetPointsGets all the points that define a set of continuous edges.
Reset重置为由两个顶点组成的一条边缘。
SetPointsSets all the points that define a set of continuous edges.
