用unity写一个跳一跳的游戏代码

以下是一个简单的跳一跳游戏的代码示例，使用Unity引擎和C#语言编写：

using UnityEngine;
using UnityEngine.SceneManagement;

public class JumpGame : MonoBehaviour
{
    public float jumpForce = 10f; // 跳跃力度
    public Rigidbody2D playerRigidbody; // 玩家刚体
    public GameObject platformPrefab; // 平台预制体
    public float platformSpawnInterval = 1.5f; // 平台生成间隔
    public float platformSpeed = 2f; // 平台移动速度
    public float platformDestroyX = -10f; // 平台销毁位置
    public Transform platformSpawnPoint; // 平台生成点
    public GameObject gameOverPanel; // 游戏结束面板

    private float lastPlatformSpawnTime; // 上次生成平台时间
    private bool isGameOver; // 游戏是否结束

    private void Update()
    {
        if (Input.GetMouseButton(0) && !isGameOver)
        {
            playerRigidbody.velocity = Vector2.up * jumpForce;
        }
    }

    private void FixedUpdate()
    {
        if (!isGameOver && Time.time - lastPlatformSpawnTime > platformSpawnInterval)
        {
            SpawnPlatform();
        }

        foreach (Transform platform in transform)
        {
            platform.position -= Vector3.right * platformSpeed * Time.deltaTime;

            if (platform.position.x < platformDestroyX)
            {
                Destroy(platform.gameObject);
            }
        }
    }

    private void SpawnPlatform()
    {
        lastPlatformSpawnTime = Time.time;

        GameObject platform = Instantiate(platformPrefab, platformSpawnPoint.position, Quaternion.identity, transform);
        platform.transform.localScale = new Vector3(Random.Range(1f, 2f), 1f, 1f);
    }

    private void OnTriggerEnter2D(Collider2D collision)
    {
        if (collision.CompareTag("Platform"))
        {
            playerRigidbody.velocity = Vector2.up * jumpForce;
            Destroy(collision.gameObject);
        }
        else if (collision.CompareTag("GameOver"))
        {
            GameOver();
        }
    }

    private void GameOver()
    {
        isGameOver = true;
        gameOverPanel.SetActive(true);
    }

    public void RestartGame()
    {
        SceneManager.LoadScene(SceneManager.GetActiveScene().name);
    }
}

请注意：这只是一个简单的示例，您可以根据自己的需求进行修改和扩展。
