UCharacterMovementComponent::GetDeltaRotation

function Engine Since 4.0

#include "GameFramework/CharacterMovementComponent.h"

Access: public Specifiers: virtualconst

Description

Returns how far the character should rotate over the given time interval, based on RotationRate.

Caveats & Gotchas

• Default implementation simply scales RotationRate by DeltaTime — it doesn't account for acceleration or current facing direction; that logic lives in ComputeOrientToMovementRotation() and PhysicsRotation().
• Called every physics substep from PhysicsRotation(), so an expensive override here has a direct, multiplied cost on movement performance.
• Overriding this is a common way to implement non-linear turn rates (e.g. faster turning at low speed) without touching PhysicsRotation() itself.

Example

Speed-dependent turn rate override C++

FRotator UMyCharacterMovementComponent::GetDeltaRotation(float DeltaTime) const
{
	const float SpeedFactor = FMath::Clamp(Velocity.Size() / MaxWalkSpeed, 0.25f, 1.f);
	return RotationRate * SpeedFactor * DeltaTime;
}
