※ 플레이어 점프 & 연속 점프 방지

	public class PlayerController : MonoBehaviour  {
	    private Rigidbody playerRb;
	    public float jumpForce = 10;
	    public float gravityModifier;
        
	    public bool isOnGround = true;
	    public bool gameOver = false;
	
	    void Start()  {
	        playerRb = GetComponent<Rigidbody>();
	        Physics.gravity *= gravityModifier;
	    }
	
	    void Update()  {
	        if (Input.GetKeyDown(KeyCode.Space) && isOnGround)  {
	            playerRb.AddForce(Vector3.up * jumpForce, ForceMode.Impulse);
	            isOnGround = false;
	        }
	    }
	
	    private void OnCollisionEnter(Collision collision)  {
	        if (collision.gameObject.CompareTag("Ground"))
	            isOnGround = true;
	        else if (collision.gameObject.CompareTag("Obstacle"))  {
	            Debug.Log("Game Over!!");
	            gameOver = true;
	        }
	    }
	}

※ 장애물 자동으로 반복 생성

	public class SpawnManager : MonoBehaviour
	{
	    public GameObject obstaclePrefab;
	    private Vector3 spawnPos = new Vector3(25, 0, 0);
	
	    private float startDelay = 2;
	    private float repeatRate = 2;
	
	    private PlayerController playerControllerScript;
	
	    void Start()
	    {
	        InvokeRepeating("SpawnObstacle", startDelay, repeatRate);
	        playerControllerScript = GameObject.Find("Player").GetComponent<PlayerController>();
	    }
	
	    void SpawnObstacle()
	    {
	        if (playerControllerScript.gameOver == false)
	            Instantiate(obstaclePrefab, spawnPos, obstaclePrefab.transform.rotation);
	    }
	}

※ 배경화면 반복 재생

	public class RepeatBackground : MonoBehaviour
	{
	    private Vector3 startPos;
	    private float repeatWidth;
	
	    void Start()
	    {
	        startPos = transform.position;
	        repeatWidth = GetComponent<BoxCollider>().size.x / 2;
	    }
	
	    void Update()
	    {
	        if (transform.position.x < startPos.x - repeatWidth)
	            transform.position = startPos;
	    }
	}

※ 배경과 장애물 이동, 그리고 장애물 파괴

	public class MoveLeft : MonoBehaviour
	{
	    public float speed = 30;
	    private float leftBound = -15;
	    private PlayerController playerControllerScript;
	
	    void Start()
	    {
	        playerControllerScript = GameObject.Find("Player").GetComponent<PlayerController>();
	    }
	
	    void Update()
	    {
	        if (playerControllerScript.gameOver == false)
	        {
	            transform.Translate(Vector3.left * Time.deltaTime * speed);
	        }
	
	        if (transform.position.x < leftBound && gameObject.CompareTag("Obstacle"))
	        {
	            Destroy(gameObject);
	        }
	    }
	}
