origin | 胶囊体在 2D 空间中的起点。 |
size | 胶囊体的大小。 |
capsuleDirection | 胶囊体的方向。 |
angle | 胶囊体的角度(以度为单位)。 |
direction | 表示胶囊体投射方向的向量。 |
results | 用于接收结果的数组。 |
distance | 将胶囊体投射的最大距离。 |
layerMask | 过滤器,用于仅在特定层上检测碰撞体。 |
minDepth | 仅包括 Z 坐标(深度)大于该值的对象。 |
maxDepth | 仅包括 Z 坐标(深度)小于该值的对象。 |
int
返回放置在 results
数组中的结果数。
向场景中投射一个胶囊体,将与胶囊体接触的碰撞体返回到提供的结果数组中。
此函数类似于 CapsuleCastAll 函数,不同之处在于其结果会返回到提供的数组中。整数返回值是与该胶囊体交叠的对象数(可能为零),但如果结果数组中没有足够的元素来报告所有这些结果,则不会调整该数组的大小。其意义在于不为这些结果分配内存,因此在经常执行时会提高垃圾回收性能。
返回的 RaycastHit2D 将返回胶囊体将与碰撞体接触的点和法线。此外,它还返回当胶囊体接触该点时胶囊体的质心。
