UKismetArrayLibrary::Array_Append
#include "Kismet/KismetArrayLibrary.h"
Access: public
Specifiers: staticBlueprintCallableCustomThunk
Description
Appends all elements of one array onto the end of another array in place.
Caveats & Gotchas
- • Displayed in Blueprint as 'Append Array' with CompactNodeTitle 'APPEND'.
- • SourceArray is left unmodified — only TargetArray is mutated; passing the same array as both parameters is not a documented or tested use case.
- • ArrayTypeDependentParams ties SourceArray's element type to TargetArray's — you cannot append an array of a different element type.
