BoxcastCommand

描述

使用此结构来设置要在作业过程中异步执行的盒体投射命令。

使用此结构计划一批盒体投射时，这些盒体投射会以异步方式并行执行。每个盒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.

Boxcast 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.ExecuteBoxcastJob is logged into the profiler. Query count information is not logged.
