使用Unity开发坦克大战游戏（六）地图创建

新建游戏物体，作为地图的构造器。  
经过拖动，可以看到(0, -8）为地图底线中点  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl8zNjM3Mjg3OQ_size_16_color_FFFFFF_t_70]  
因此需要将老家实例化在(0, -8）这个位置。

private void Awake()
        { 
            //实例化老家
            Instantiate(item[0], new Vector3(0, -8, 0), Quaternion.identity);//物体 坐标 无旋转
            //墙围着老家
            Instantiate(item[1], new Vector3(-1, -8, 0), Quaternion.identity);
            Instantiate(item[1], new Vector3(1, -8, 0), Quaternion.identity);
            Instantiate(item[1], new Vector3(0, -7, 0), Quaternion.identity);
            Instantiate(item[1], new Vector3(-1, -7, 0), Quaternion.identity);
            Instantiate(item[1], new Vector3(1, -7, 0), Quaternion.identity);
        }

在awake方法里面实例化就行了

发现wall可能比较小，于是将wall调大一点

于是就实例化出来了。

# 为了防止地图产生混乱，需要将左右的物体产生在mapcration下面 #

关于unity的gameobject和tansform可以参考博客：[https://www.jianshu.com/p/7eb7cd198de4][https_www.jianshu.com_p_7eb7cd198de4]

using System.Collections;
    using System.Collections.Generic;
    using UnityEngine;
    
    public class MapCeation : MonoBehaviour
    { 
        public GameObject[] item; //定义存放gameobject的数组
        //0.老家 1.墙 2.障碍 3.出生效果 4.河流 5.草 6.空气墙
        private void Awake()
        { 
            //实例化老家
            CreateItem(item[0], new Vector3(0, -8, 0), Quaternion.identity);//物体 坐标 无旋转
            //墙围着老家
            CreateItem(item[1], new Vector3(-1, -8, 0), Quaternion.identity);
            CreateItem(item[1], new Vector3(1, -8, 0), Quaternion.identity);
            CreateItem(item[1], new Vector3(0, -7, 0), Quaternion.identity);
            CreateItem(item[1], new Vector3(-1, -7, 0), Quaternion.identity);
            CreateItem(item[1], new Vector3(1, -7, 0), Quaternion.identity);
        }
        private void CreateItem(GameObject createGameObject, Vector3 createPosion, Quaternion createRotaion)
        { 
            GameObject itemGo = Instantiate(createGameObject, createPosion, createRotaion);
            itemGo.transform.SetParent(gameObject.transform);
        }
    }

绑定parent就可以看到，创建之后都在mapcreation下面了  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl8zNjM3Mjg3OQ_size_16_color_FFFFFF_t_70 3]

# 随机地图场景生成 #

定义一个存放位置的列表

private List<Vector3> itemPosition = new List<Vector3>();//已经有东西位置的列表
     private void CreateItem(GameObject createGameObject, Vector3 createPosion, Quaternion createRotaion)
    { 
        GameObject itemGo = Instantiate(createGameObject, createPosion, createRotaion);
        itemGo.transform.SetParent(gameObject.transform);
        itemPosition.Add(createPosion);//产生的位置放在列表里面
    }

# 产生玩家和敌人 #

固定位置生成玩家注意getcomponent方法来获取bool值，然后更改是否是玩家

//初始化玩家
    GameObject go = Instantiate(item[5], new Vector3(-2, -8, 0), Quaternion.identity);
    itemPosition.Add(new Vector3(-2, -8, 0)); //防止出生地生成物体
    go.GetComponent<Born>().createPlayer = true;
    
    //初始化敌人，不需要设置bool值，因为默认的false
    CreateItem(item[5], new Vector3(-10, 8, 0), Quaternion.identity);
    CreateItem(item[5], new Vector3(0, 8, 0), Quaternion.identity);
    CreateItem(item[5], new Vector3(10, 8, 0), Quaternion.identity);

运行之后就可以看到随机地图的生成了。

在三个位置随机的不停产生敌人

private void CreateEnemy()
        { 
            int num = Random.Range(0, 3);//因为有三个位置需要生成敌人
            Vector3 EnemyPos;
            if (num == 0)
            { 
                EnemyPos = new Vector3(-10, 8, 0);
            }
            else if (num == 1)
            { 
                EnemyPos = new Vector3(0, 8, 0);
            }
            else
            { 
                EnemyPos = new Vector3(10, 8, 0);
            }
            CreateItem(item[5], EnemyPos, Quaternion.identity);
        }

然后不停产生敌人，使用InvokeRepeating方法

InvokeRepeating("CreateEnemy", 4f, 5f);  //方法名，延时，每隔多久调用一次

using System.Collections;
    using System.Collections.Generic;
    using UnityEngine;
    
    public class MapCeation : MonoBehaviour
    { 
        public GameObject[] item; //定义存放gameobject的数组
        //0.老家 1.墙 2.障碍 3.河流 4.草 5.出生效果 6.空气墙
        private List<Vector3> itemPosition = new List<Vector3>();//已经有东西位置的列表
        private int numOfObject = 80; //随机化物体的数量
        private void Awake()
        { 
            //实例化老家
            CreateItem(item[0], new Vector3(0, -8, 0), Quaternion.identity);//物体 坐标 无旋转
            //墙围着老家
            CreateItem(item[1], new Vector3(-1, -8, 0), Quaternion.identity);
            CreateItem(item[1], new Vector3(1, -8, 0), Quaternion.identity);
            CreateItem(item[1], new Vector3(0, -7, 0), Quaternion.identity);
            CreateItem(item[1], new Vector3(-1, -7, 0), Quaternion.identity);
            CreateItem(item[1], new Vector3(1, -7, 0), Quaternion.identity);
            //实例化外围墙
            for (int i = -11; i <= 11; i++)
            { 
                CreateItem(item[6], new Vector3(i, -9, 0), Quaternion.identity);
                CreateItem(item[6], new Vector3(i, 9, 0), Quaternion.identity);
            }
            for (int i = -8; i <= 8; i++)
            { 
                CreateItem(item[6], new Vector3(-11, i, 0), Quaternion.identity);
                CreateItem(item[6], new Vector3(11, i, 0), Quaternion.identity);
            }
            //初始化玩家
            GameObject go = Instantiate(item[5], new Vector3(-2, -8, 0), Quaternion.identity);
            itemPosition.Add(new Vector3(-2, -8, 0)); //防止出生地生成物体
            go.GetComponent<Born>().createPlayer = true;
    
            //初始化敌人，不需要设置bool值，因为默认的false
            CreateItem(item[5], new Vector3(-10, 8, 0), Quaternion.identity);

            CreateItem(item[5], new Vector3(10, 8, 0), Quaternion.identity);
    
            InvokeRepeating("CreateEnemy", 4f, 5f);  //方法名，延时，每隔多久调用一次
    
            //实例化随机物体
            int j = 0;
            while (j < numOfObject)
            { 
                Vector3 createPosion = new Vector3(Random.Range(-9, 10), Random.Range(-7, 8), 0);
                if (IsIntheList(createPosion) == false)
                { 
                    CreateItem(item[Random.Range(1, 5)], createPosion, Quaternion.identity);
                    j += 1;
                }
            }
        }
    
        private void CreateItem(GameObject createGameObject, Vector3 createPosion, Quaternion createRotaion)
        { 
            GameObject itemGo = Instantiate(createGameObject, createPosion, createRotaion);
            itemGo.transform.SetParent(gameObject.transform);
            itemPosition.Add(createPosion);//产生的位置放在列表里面
        }
    
        private bool IsIntheList(Vector3 position)
        { 
            for (int i = 0; i < itemPosition.Count; i++)
            {

                { 
                    return true;
                }
            }
            return false;
        }
    
        private void CreateEnemy()
        {
