根因分析

当碰撞器是触发器且 QueryTriggerInteraction.UseGlobal 设置时，Physics.RaycastNonAlloc 调用会返回重复命中，导致数组溢出。

English

A Physics.RaycastNonAlloc call returns duplicate hits when the collider is a trigger and QueryTriggerInteraction.UseGlobal is set, causing array overflow.

解决方案

  1. Set QueryTriggerInteraction.Ignore in the RaycastNonAlloc call to ignore trigger colliders.
  2. Use Physics.RaycastAll instead and deduplicate hits by collider instance ID.

无效尝试

常见但无效的做法:

  1. 90% 失败

    The error occurs because the same collider is hit multiple times, not because the buffer is too small.

  2. 70% 失败

    Changing isTrigger alters collision behavior and may not be acceptable for the game design.
