CustomCollider2D.customShapeCount

描述

分配给碰撞器的自定义 PhysicsShape2D 的总数。(只读)

此处表示的所有形状都包含 customVertexCount 的总顶点数量。

注意: 此属性不应与 Collider2D.shapeCount 混淆，后者是 Collider2D 上活动形状的数量。 CustomCollider2D 也具有此属性。如果 Collider2D 被禁用、不活动或处于 错误 状态，则 Collider2D.shapeCount 将为零，而 customShapeCount 将始终是分配的自定义 PhysicsShape2D 的数量。
