跳的代码

自动移动

结束动画

碰撞判定

C#小白的期末作业。。。

谷歌小恐龙游戏是一个浏览器自带的小游戏。

首先打开谷歌Chrome，在地址栏输入：chrome://dino/

在unity里导入小恐龙所要的图片；

给小恐龙加盒子碰撞器Box Collider2D,物理引擎Rigidbody 2D

同样路也要加盒子碰撞器Box Collider2D 来防止小恐龙掉下

跳的代码：

using System;
using System.Collections;
using System.Collections.Generic;
using System.Collections.Specialized;
using UnityEngine;

public class game1 : MonoBehaviour
{
    Rigidbody2D rb;
    public float jump;  //跳的高度的值
    bool isjumping;
    public GameManager gm;

    // Start is called before the first frame update
    void Start()
    {
        rb = GetComponent<Rigidbody2D>();
        isjumping = false;
    } 

    // Update is called once per frame
    void Update()
    {
        if (Input.GetKeyDown(KeyCode.Space) && isjumping == false)
        {
            rb.velocity = new Vector2(0, jump);
            isjumping = true;
        }
    }
//小恐龙只有碰撞后才可以跳，这样就可以防止小恐龙一直跳
    private void OnCollisionEnter2D(Collision2D collision)
    {
        isjumping = false;

//小恐龙碰撞仙人掌Cactus时弹出GameOver画面
        if (collision.gameObject.tag == "Cactus")
        {
            gm.GameOver();
        }
        
    }
}

自动移动：

using System.Collections;
using System.Collections.Generic;
using System.Threading;
using System.Timers;
using UnityEngine;

public class NewBehaviourScript : MonoBehaviour
{
    public float movementSpeed;    //移动的速度
    public float startPosition;    //循环开始的位置
    public float endPosition;      //循环结束的位置

    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        transform.position = new Vector2(transform.position.x - movementSpeed * Time.deltaTime , transform.position.y);

        if (transform.position.x <= endPosition)
        {
            if(gameObject.tag == "Cactus")
            {
                Destroy(gameObject);
            }
            else
            {
                transform.position = new Vector2(startPosition, transform.position.y);
            }  
        }
    }
}

仙人掌的自动生成

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;

public class GameManager : MonoBehaviour
{
    public GameObject cactus;
    public GameObject cactusSpawnPosition;
    public float spawnTime;                    //生成的时间
    float timer;
    public GameObject GameOverScene;

    // Start is called before the first frame update
    void Start()
    {
        Time.timeScale = 1;
    }

    // Update is called once per frame
    void Update()
    {
        timer += Time.deltaTime;

        if(timer >= spawnTime)
        {
            Instantiate(cactus, cactusSpawnPosition.transform);
            timer = 0;
        }

    }
//GameOver 调用
    public void GameOver ()
    {
        Time.timeScale = 0;
        GameOverScene.SetActive(true);
    }
//GameOverButton按钮的“lv1”场景的调用
    public void Restart ()
    {
        SceneManager.LoadScene("lv1");
    }
}

结束动画

把GameOverText和GameOverButton放入面板GameOver里

效果：

碰撞判定

给仙人掌定义Cactus的标签

当小恐龙碰撞Cactus时弹GameOver

我们在开始的小恐龙的脚本里写就可以了

void Update()
{
if (Input.GetKeyDown(KeyCode.Space) && isjumping == false)
{
rb.velocity = new Vector2(0, jump);
isjumping = true;
}
}
//小恐龙只有碰撞后才可以跳，这样就可以防止小恐龙一直跳
private void OnCollisionEnter2D(Collision2D collision)
{
isjumping = false;

//小恐龙碰撞仙人掌Cactus时弹出GameOver画面
if (collision.gameObject.tag == "Cactus")
{
gm.GameOver();
}
