UKismetMathLibrary::SetQuaternionSpringStateAngularVelocity

function Engine Blueprint Since 4.0

#include "Kismet/KismetMathLibrary.h"

Access: public Specifiers: staticUFUNCTIONBlueprintCallable

Description

Overwrites the internal angular velocity stored in a quaternion spring state, useful for injecting an instantaneous rotational impulse into an ongoing QuaternionSpringInterp.

Caveats & Gotchas

• AngularVelocity is an axis-angle vector — its direction is the rotation axis and its magnitude is speed in radians/second — not a rotator or Euler angles.
• Only affects the momentum used on the spring's next update; the rotation value being interpolated does not snap or change immediately.

Signature

static void SetQuaternionSpringStateAngularVelocity(UPARAM(ref) FQuaternionSpringState& SpringState, FVector AngularVelocity)

Parameters

Name	Type	Description	Default
SpringState	FQuaternionSpringState&	The spring state whose internal angular velocity is overwritten.	—
AngularVelocity	FVector	The new angular velocity to assign, as an axis-angle vector in radians/second.	—

Return Type

void

Example

Kick a rotational spring on impact C++

void AMyProp::OnHit()
{
    UKismetMathLibrary::SetQuaternionSpringStateAngularVelocity(TiltSpringState, FVector(0.f, 3.f, 0.f));
}
