Parameters
| Name | Remarks |
|---|---|
| Start | Start of line segment. |
| End | End of line segment. |
| HalfSize | Distance from the center of box along each axis |
| Orientation | Orientation of the box |
| TraceChannel | |
| bTraceComplex | True to test against complex collision, false to test against simplified collision. |
| OutHits | A list of hits, sorted along the trace from start to finish. The blocking hit will be the last hit, if there was one. |
