hi all,

I started with ball game c++ template. I want to imediately cancel the ball movement when i call my StopBallMovement() function .
here is my function to move the ball :

void ABallBall::MoveForward(float Val)
{
		// find out which way is forward
		const FRotator Rotation = Controller->GetControlRotation();
		const FRotator YawRotation(0, Rotation.Yaw, 0);

		// fVector mouvement 
		const FVector Direction = FRotationMatrix(YawRotation).GetUnitAxis(EAxis::Y);
		Ball->AddTorque(Direction * Val * RollTorque  );
}

Thanks
