| ray | @param ray Начальная точка и направление луча. |
| results | The buffer to store the hits into. |
| maxDistance | The max distance the rayhit is allowed to be from the start of the ray. |
| layerMask | A Layer mask that is used to selectively ignore colliders when casting a ray. |
| queryTriggerInteraction | Specifies whether this query should hit Triggers. |
int
The amount of hits stored into the results buffer.
Cast a ray through the Scene and store the hits into the buffer.
Like Physics.RaycastAll, but generates no garbage.
The raycast query ends when there are no more hits and/or the results buffer is full. The order of the results is undefined. When a full buffer is returned it is not guaranteed that the results are the closest hits and the length of the buffer is returned. If a null buffer is passed in, no results are returned and no errors or exceptions are thrown.
