UKismetMathLibrary::ResetVectorSpringState
#include "Kismet/KismetMathLibrary.h"
Access: public
Specifiers: staticUFUNCTIONBlueprintCallable
Description
Resets a vector spring's velocity and previous-target tracking back to zero/invalid, as if it had never run. Use this before reusing a spring for an unrelated position or after a large discontinuity such as a teleport.
Caveats & Gotchas
- • Only clears the spring's internal state, not whatever Current value you pass into VectorSpringInterp next — reset that separately if needed to avoid the value snapping visibly on the next call.
- • Vector springs interpolate all three axes with a single shared Stiffness/Damping pair in VectorSpringInterp, so resetting only affects momentum, not per-axis behaviour.
