UKismetMathLibrary::BreakVector2D
#include "Kismet/KismetMathLibrary.h"
Access: public
Specifiers: staticBlueprintPureUFUNCTION
Description
Decomposes an FVector2D into its individual X and Y double components via output parameters. In Blueprint this appears as the 'Break Vector 2D' node.
Caveats & Gotchas
- • In C++, accessing InVec.X and InVec.Y directly is equivalent and more readable; this function exists primarily to support Blueprint's NativeBreakFunc pattern.
- • X and Y are output-only reference parameters — their initial values before the call are irrelevant and will be overwritten unconditionally.
