이전 강의에서 과제를 내주셨는데 , 조준을 했을시에 어떻게 줄어들까에 대한 과제를 내주셨다.

그래서 해당 구현을 다음과 같이 했다

void AShooterCharacter::CalculateCrosshairSpread(float DeltaTime)
{
	FVector2D WalkSpeedRange{ 0.f,600.f };
	FVector2D VelocityMultiplierRange{ 0.f,1.f };
	FVector Velocity{ GetVelocity() };
	Velocity.Z = 0;
	// Caculate Crosshair Velocity Factor
	CrosshairVelocityFactor = FMath::GetMappedRangeValueClamped(WalkSpeedRange, VelocityMultiplierRange, Velocity.Size());

	// Caculate Crosshair in air Factor
	if (GetCharacterMovement()->IsFalling())
	{
		// Spread the crosshairs slowly while in air
		CrosshairInAirFactor = FMath::FInterpTo(CrosshairInAirFactor, 2.25f, DeltaTime, 2.25f);
	}
	else // Character is on the ground
	{
		// Shrink the crosshairs rapidly while on the ground
		CrosshairInAirFactor = FMath::FInterpTo(CrosshairInAirFactor, 0.0f, DeltaTime, 30.0f);
	}

	if (bAiming)
		CrosshairAimFactor = FMath::FInterpTo(CrosshairAimFactor, 0.5f, DeltaTime, 30.0f);
	else
		CrosshairAimFactor = FMath::FInterpTo(CrosshairAimFactor, 0.0f, DeltaTime, 30.0f);
	CrosshairSpreadMultiplier = 0.5f + CrosshairVelocityFactor + CrosshairInAirFactor - CrosshairAimFactor;
}

오 나랑 거의 똑같이 구현하셨다
