#include "Kismet/KismetArrayLibrary.h"
Access: public
Specifiers: staticBlueprintPureCustomThunk
Description
Returns true if the array has no elements.
Caveats & Gotchas
- • Marked BlueprintThreadSafe, so it's safe to call from async Blueprint contexts.
- • Equivalent to checking Array_Length(TargetArray) == 0, but reads more clearly as a branch condition.
