중력 반사 미사일

저번 반사하는 미사일에 추가로 중력을 더한 미사일을 만드는게 과제였습니다.

//bullet.cpp
#include "stdafx.h"

Bullet::Bullet()
{
	missile.SetLocalPos(Vector2(2000.0f, 2000.0f));
	missile.scale.x = 30.0f;
	missile.rotation = 0.0f;
	missile.isVisible = false;

	missilePet.SetParentRT(missile);
	missilePet.SetLocalPos(Vector2(50.0f, 50.0f));
	missilePet.scale = Vector2(10.0f, 10.0f);
	missilePet.rotation = 0.0f;
	missilePet.isAxis = true;
	missilePet.isVisible = false;
}

void Bullet::Update(ObRect player)
{
	if (!missilePet.isVisible) return;

	cout << scalar << endl;

	Vector2 dir = fireDir * scalar + DOWN * gravity;

	missile.MoveWorldPos(dir * DELTA);
	missile.rotation = Utility::DirToRadian(dir);

	missilePet.revolution += 360.0f * ToRadian * DELTA;

	gravity += 300.0f * DELTA;

	missile.Update();
	missilePet.Update();
}

void Bullet::LateUpdate()
{
	//위
	if (missile.GetWorldPos().y >= app.GetHalfHeight() + CAM->position.y)
	{
		fireDir.y *= -1.0f;
		gravity *= -0.7f;
		scalar *= 0.7f;
		missile.SetWorldPosY(app.GetHalfHeight() + CAM->position.y);
	}
	//아래
	if (missile.GetWorldPos().y <= -app.GetHalfHeight() + CAM->position.y)
	{
		fireDir.y *= -1.0f;
		gravity *= -0.7f;
		scalar *= 0.7f;
		missile.SetWorldPosY(-app.GetHalfHeight() + CAM->position.y);
	}
	//왼쪽
	if (missile.GetWorldPos().x <= -app.GetHalfWidth() + CAM->position.x)
	{
		fireDir.x *= -1.0f;
		gravity *= -0.7f;
		scalar *= 0.7f;
		missile.SetWorldPosX(-app.GetHalfWidth() + CAM->position.x);
	}
	//오른쪽
	if (missile.GetWorldPos().x >= app.GetHalfWidth() + CAM->position.x)
	{
		fireDir.x *= -1.0f;
		gravity *= -0.7f;
		scalar *= 0.7f;
		missile.SetWorldPosX(app.GetHalfWidth() + CAM->position.x);
	}
}

void Bullet::Render()
{
	if (!missilePet.isVisible) return;
	missile.Render();
	missilePet.Render();
}

bool Bullet::Shoot(Vector2 fireDir, float scalar, Vector2 firePos)
{
	if (!missilePet.isVisible)
	{
		missile.isVisible = true;
		missilePet.isVisible = true;
		missilePet.revolution = 0.0f;
		missile.rotation = Utility::DirToRadian(fireDir);
		missile.SetWorldPos(firePos);
		this->fireDir = fireDir;
		gravity = 0.0f;

		this->scalar = scalar * 5.0f;
		return true;
	}
	return false;
}

코드입니다.
