UKismetArrayLibrary::Array_Length
#include "Kismet/KismetArrayLibrary.h"
Access: public
Specifiers: staticBlueprintPureCustomThunk
Description
Returns the number of elements in an array.
Caveats & Gotchas
- • Registered under the Blueprint keywords 'num size count', so any of those terms find the 'Length' node in the palette.
- • Marked BlueprintThreadSafe, so it can safely be called from async Blueprint contexts alongside other pure array queries.
- • In C++ this is just TargetArray.Num() — Array_Length exists only to back the Blueprint pure node.
