UKismetArrayLibrary::Array_Resize
#include "Kismet/KismetArrayLibrary.h"
Access: public
Specifiers: staticBlueprintCallableCustomThunk
Description
Resizes an array to the given size, truncating extra elements or appending default-constructed ones as needed.
Caveats & Gotchas
- • Growing the array fills new slots with the element type's default value (0, empty string, nullptr, etc.), not copies of the last element.
- • Shrinking discards elements past the new size permanently — there is no undo.
- • A negative Size is treated as invalid and logs a warning rather than clearing the array.
