层碰撞矩阵定义了哪些层可以接触其他层。此外,您还可以根据每个 Collider 或针对附加到特定 Rigidbody 或 ArticulationBody 的所有 Collider 包含和排除层。任何接触都涉及两个不同的 Collider 实例。不幸的是,这会导致一个 Collider 决定它应该接触另一个 Collider,但另一个 Collider 决定它不应该接触。有一些规则来决定如何处理这些情况。
两个 Collider(这里分别称为 A 和 B)之间做出决定的规则按以下顺序进行
其他资源:Collider.includeLayers、Collider.excludeLayers、Rigidbody.includeLayers、Rigidbody.excludeLayers、ArticulationBody.includeLayers、ArticulationBody.excludeLayers。
