// 本脚本适用于纵向2D游戏的屏幕宽度匹配
// 如果是横向卷轴游戏，不需要用这个脚本
public class CamRatioAdapter : MonoBehaviour

    // 测试结果：屏幕宽高比3:4 = 0.75对应摄像机size3.75
    // 屏幕宽高比9:16 = 0.5625对应摄像机大小5

同样添加组件

unity发射器_unity_19

并修改层级

unity发射器_c#_20

写个Enemy Move脚本,挂到小怪兽上

EnemyMove.cs

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

public class EnemyMove : MonoBehaviour
{
    public float speed = 3;
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        transform.position += Vector3.down * speed * Time.deltaTime;
    }
}

为了防止子弹一直存在，积累太多，写个脚本挂在子弹上，4s后自动销毁

unity发射器_System_21

DelayDestroy.cs

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

public class DelayDestroy : MonoBehaviour
{
    // Start is called before the first frame update
    public float time = 1;
    void Start()
    {
        StartCoroutine(Delay());
    }

    IEnumerator Delay()
    {
        yield return new WaitForSeconds(time);
        Destroy(gameObject);
    }

}

为了防止玩家出框，给玩家设置边界（左右2.3，上下4.3）并加上[Serializable]特性使边界可编辑

写个Border类放到Border.cs脚本里

Border.cs

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

public class Border : MonoBehaviour
{
    public float top = 4.3f;
    public float bottom = -4.3f;
    public float left = -2.3f;
    public float right = 2.3f;
}

在PlayerCha.cs中调用Border

//移动的边界范围
Border moveBorder;
//Clamp:限定范围
pos.x = Mathf.Clamp(pos.x, moveBorder.left, moveBorder.right);
pos.y = Mathf.Clamp(pos.y, moveBorder.bottom, moveBorder.top);
transform.position = pos;

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

public class PlayerCha : MonoBehaviour
{
    public Transform prefabBullet;
    public float speed = 3;

    public float fireCD = 0.2f;
    float lastFireTime;

    //移动的边界范围
    Border moveBorder;

    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        
    }
    public void Move(Vector3 input)
    {
        Vector3 pos = transform.position + input * speed * Time.deltaTime;

        //Clamp:限定范围
        pos.x = Mathf.Clamp(pos.x, moveBorder.left, moveBorder.right);
        pos.y = Mathf.Clamp(pos.y, moveBorder.bottom, moveBorder.top);

        transform.position = pos;
        //transform.position += input * speed * Time.deltaTime;       
    }
    public void Fire()
    {
        if(Time.time < lastFireTime + fireCD)
        {
            return;
        }

        Vector3 pos = transform.position + new Vector3(0, 0.8f, 0);
        Transform bullet = Instantiate(prefabBullet, pos, Quaternion.identity);
        lastFireTime = Time.time;

    }

}

创建怪物营地

创建空物体Spawner

Spawner.cs

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

public class Spawner : MonoBehaviour
{
    //多个怪物的预制体
    public List<Transform> monsters;

    public float minTime = 0.5f;
    public float maxTime = 2;

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

    IEnumerator Create()
    {
        while (true)
        {
            //创建怪物

            //随机怪物下标
            int i = Random.Range(0, monsters.Count);
            //随机位置
            Vector3 pos = new Vector3(Random.Range(-2.1f,2.1f), transform.position.y, 0);
            Transform m = Instantiate(monsters[i], pos, Quaternion.identity);


            //等一段时间
            float t = Random.Range(minTime, maxTime);
            yield return new WaitForSeconds(t);

        }
    }

    // Update is called once per frame
    void Update()
    {
        
    }
}

把脚本挂在空物体上，把前面做好的小怪兽拖到Monsters列表里

    public float minY = 2.6f;
    public float minX = -2.3f;
    public float maxX = 2.3f;

    public float speed = 3f;

    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()

        switch (state)
        {
            case State.Down:
