UKismetMathLibrary::BreakQuat
#include "Kismet/KismetMathLibrary.h"
Access: public
Specifiers: staticBlueprintPure
Description
Decomposes an FQuat into its raw X, Y, Z, W float components. Primarily used by the Blueprint Break node for FQuat.
Caveats & Gotchas
- • The raw XYZW components have no direct human-readable meaning as angles — to get human-readable rotations, convert to FRotator first using FQuat::Rotator().
- • Storing and restoring a quaternion via its XYZW components is numerically safe, but if the original was not unit-length, the broken-out values will reflect that non-normalised state.
