UCharacterMovementComponent::ComputeOrientToMovementRotation
#include "GameFramework/CharacterMovementComponent.h"
Access: public
Specifiers: virtualconst
Description
Computes the target rotation the character should turn toward based on its current Acceleration, used by PhysicsRotation() when bOrientRotationToMovement is true.
Caveats & Gotchas
- • Only called when bOrientRotationToMovement is true — if that flag is false (e.g. controller-driven rotation), this function is never reached, so overriding it alone won't change rotation behaviour.
- • Default implementation targets the direction of Acceleration, not Velocity, so a character sliding sideways with zero input acceleration will not reorient via this path.
- • Returns CurrentRotation unchanged (no turn) when Acceleration is near zero, since there's no meaningful direction to face.
Signature
virtual FRotator ComputeOrientToMovementRotation(const FRotator& CurrentRotation, float DeltaTime, FRotator& DeltaRotation) const;Parameters
| Name | Type | Description | Default |
|---|---|---|---|
| CurrentRotation | const FRotator& | Current rotation of the Character. | — |
| DeltaTime | float | Time slice for this movement. | — |
| DeltaRotation | FRotator& | Proposed rotation change based on DeltaTime * RotationRate; may be modified by this function. | — |
Return Type
FRotator Example
Orienting toward velocity instead of acceleration C++
FRotator UMyCharacterMovementComponent::ComputeOrientToMovementRotation(const FRotator& CurrentRotation, float DeltaTime, FRotator& DeltaRotation) const
{
if (Velocity.SizeSquared() < KINDA_SMALL_NUMBER)
{
return CurrentRotation;
}
return Velocity.ToOrientationRotator();
