[Unreal Engine] FMath::FInterpConstantTo

Il FMath::FInterpConstantTo interpola il float dalla Posizione attuale al Target desiderato con un andamento costante.

Sintassi:

 static float FInterpConstantTo
(
    float Current,
    float Target,
    float DeltaTime,
    float InterpSpeed
)

Esempio sulla rotazione

Nella classe corrente di MioScript.h:

 private:
      float TargetYaw = 90.f; 
      float InitialYaw = 0.f; 
      float CurrentYaw;

MioScript.cpp:

 // Called every frame
void UMioScript::TickComponent(float DeltaTime, ELevelTick TickType, FActorComponentTickFunction* ThisTickFunction)
{
      Super::TickComponent(DeltaTime, TickType, ThisTickFunction);

      // HERE BEGIN CODE
      CurrentYaw = GetOwner()->GetActorRotation().Yaw;
      FRotator OpenDoor(0.f, TargetYaw, 0.f);

      /*
      Change Yaw of OpenDoor      
      StartingYaw
      TargetYaw: CurrentYaw
      0-1
      */
      OpenDoor.Yaw = FMath::FInterpConstantTo(CurrentYaw, TargetYaw, DeltaTime, 45);
      GetOwner()->SetActorRotation(OpenDoor);
}
