UKismetMathLibrary::FromHours
#include "Kismet/KismetMathLibrary.h"
Access: public
Specifiers: staticUFUNCTIONBlueprintPure
Description
Constructs an FTimespan representing the given number of hours. Fractional values are accepted, so 1.5 produces a 90-minute span.
Caveats & Gotchas
- • There is no range check on the input — extremely large values will silently overflow the underlying int64 tick counter. The safe usable range is roughly ±29,000 years.
- • Negative hours produce negative timespans, which are valid but can mislead callers expecting a duration to always be positive. Consider asserting Days >= 0 in game code if sign matters.
