使用此结构来设置在作业过程中异步执行的球体投射命令。
使用此结构计划一批球体投射时,这些球体投射会以异步方式并行执行。每个球体投射的结果会写入结果缓冲区。由于结果是异步写入,因此在作业完成之前无法访问结果缓冲区。
The results for a command at index N in the command buffer are stored at index N * maxHits in the results buffer.
Spherecast command also allows you to control whether or not Trigger colliders and back-face triangles generate a hit. Use QueryParameters to control hit flags.
Note: Only BatchQuery.ExecuteSpherecastJob is logged into the profiler. Query count information is not logged.
