point | 世界空间中的点。 |
layerMask | 筛选器,用于检查仅在指定层上的对象。 |
minDepth | 仅包括 Z 坐标(深度)大于或等于该值的对象。 |
maxDepth | 仅包括 Z 坐标(深度)小于或等于该值的对象。 |
Collider2D 与该点重叠的碰撞体。
检查碰撞体是否与空间中的某个点重叠。
可选的 layerMask 可让测试仅检查特定层上的对象。
虽然 Z 轴与 2D 中的渲染或碰撞无关,但您可以使用 minDepth 和 maxDepth 参数根据其 Z 轴坐标筛选对象。如果有多个碰撞体与该点重叠,则返回 Z 坐标值最小的碰撞体。如果该点上没有任何碰撞体,则返回 Null。
另请参阅:OverlapPointAll、OverlapPointNonAlloc。
point | 世界空间中的点。 |
contactFilter | 接触筛选器,用于以不同方式筛选结果,例如按层遮罩、Z 深度。注意,法线角度不用于重叠测试。 |
results | 用于接收结果的数组。该数组的大小决定可返回的结果的最大数量。 |
int
返回放置在 results
数组中的结果数。
检查碰撞体是否与世界空间中的某个点重叠。
该函数返回找到的碰撞体数,并将这些碰撞体放入 results
数组。也可以通过 contactFilter
对结果进行过滤。注意,按法线角筛选不适用于重叠函数。
