UWorld::SweepMultiByChannel

Sweep a shape against the world and return all initial overlaps using a specific channel (including blocking) if requested, then overlapping hits and then first blocking hit Results are sorted, so a blocking hit (if found) will be the last element of the array Only the single closest blocking result will be generated, no tests will be done after that

Remarks

Sweep a shape against the world and return all initial overlaps using a specific channel (including blocking) if requested, then overlapping hits and then first blocking hit Results are sorted, so a blocking hit (if found) will be the last element of the array Only the single closest blocking result will be generated, no tests will be done after that

Returns

TRUE if OutHits contains any blocking hit entries

Parameters

TraceChannel

The 'channel' that this ray is in, used to determine which components to hit

CollisionShape

Params

Additional parameters used for the trace
