1.随机生成Tile(一)

在GameManager中添加随机生成砖块和从资源池取出物体的代码

public enum ObjectType
    {
        Tile,
        Item,
        Coin,
        Enemy,
        Bullet
    }
        //tile池子
        public Queue<GameObject> tilePool = new Queue<GameObject>();
        public Queue<GameObject> itemPool = new Queue<GameObject>();
        public Queue<GameObject> coinPool = new Queue<GameObject>();
        public Queue<GameObject> enemyPool = new Queue<GameObject>();
        public Queue<GameObject> bulletPool = new Queue<GameObject>();
    
        /// <summary>
        /// 随机生成砖块
        /// </summary>
        void GenerateTile()
        {
            GameObject go = GetInactiveObject(ObjectType.Tile);
        }
    
        /// <summary>
        /// 从池子取物体
        /// </summary>
        /// <param name="type"></param>
        /// <returns></returns>
        public GameObject GetInactiveObject(ObjectType type)
        {
            switch (type)
            {
                case ObjectType.Tile:
                    return tilePool.Dequeue();
                case ObjectType.Item:
                    return itemPool.Dequeue();
                case ObjectType.Coin:
                    return coinPool.Dequeue();
                case ObjectType.Enemy:
                    return enemyPool.Dequeue();
                case ObjectType.Bullet:
                    return bulletPool.Dequeue();
                default:
                    return null;
            }
        }

在GameSetting中给每个砖块添加权重（生成的概率）

2.随机生成Tile(二)

给所有tile赋值，然后在GameManager中计算它们的权值并且随机生成

//获取权值所有
        void GetAllWeight()
        {
            float sum = 0;
            sum += advance.normalTile.weight;
            sum += advance.brokenTile.weight;
            sum += advance.oneTimeOnly.weight;
            sum += advance.springTile.weight;
            sum += advance.movingVertically.weight;
            sum += advance.movingHorizontally.weight;
            totalsum = sum;
        }
    
        /// <summary>
        /// 随机生成砖块
        /// </summary>
        void GenerateTile()
        {
            GameObject go = GetInactiveObject(ObjectType.Tile);
            float rand = Random.Range(0, totalsum);
        }
    
        private void Start()
        {
            //sum赋值
            GetAllWeight();
            //初始化对象池
            GenerateTilePool();
    
            //生成物体
            for (int i = 0; i < initialSize; i++)
            {
                GenerateTile();
            }
        }

3.随机生成Tile(三)

GameManager中添加通过权值来设置tile类型的代码

int SetTileByRandomNumber(float number)
        {
            if (number <= advance.normalTile.weight)
                return 0;
            else if (number <= (advance.normalTile.weight + advance.brokenTile.weight))
                return 1;
            else if (number <= (advance.normalTile.weight + advance.brokenTile.weight + advance.oneTimeOnly.weight))
                return 2;
            else if (number <= (advance.normalTile.weight + advance.brokenTile.weight + advance.oneTimeOnly.weight + advance.springTile.weight))
                return 3;
            else if (number <= (advance.normalTile.weight + advance.brokenTile.weight + advance.oneTimeOnly.weight + advance.springTile.weight + advance.movingHorizontally.weight))
                return 4;
            else if (number <= (advance.normalTile.weight + advance.brokenTile.weight + advance.oneTimeOnly.weight + advance.springTile.weight + advance.movingHorizontally.weight + advance.movingVertically.weight))
                return 5;
    
            return -1;
        }

4.随机生成Tile(四)

完善随机生成砖块

/// <summary>
        /// 随机生成砖块
        /// </summary>
        void GenerateTile()
        {
            GameObject go = GetInactiveObject(ObjectType.Tile);
            float rand = Random.Range(0, totalsum);
            int randNumber = SetTileByRandomNumber(rand);
    
            Vector2 pos = new Vector2(Random.Range(-4.5f, 4.5f), currentY);
            switch (randNumber)
            {
                case 0:
                    go.transform.position = pos;
                    currentY += Random.Range(advance.normalTile.minHeight, advance.normalTile.maxHeight);
                    go.name = "0";
                    go.SetActive(true);
                    break;
                case 1:
                    go.transform.position = pos;
                    currentY += Random.Range(advance.brokenTile.minHeight, advance.brokenTile.maxHeight);
                    go.name = "1";
                    go.SetActive(true);
                    break;
                case 2:
                    go.transform.position = pos;
                    currentY += Random.Range(advance.oneTimeOnly.minHeight, advance.oneTimeOnly.maxHeight);
                    go.name = "2";
                    go.SetActive(true);
                    break;
                case 3:
                    go.transform.position = pos;
                    currentY += Random.Range(advance.springTile.minHeight, advance.springTile.maxHeight);
                    go.name = "3";
                    go.SetActive(true);
                    break;
                case 4:
                    go.transform.position = pos;
                    currentY += Random.Range(advance.movingHorizontally.minHeight, advance.movingHorizontally.maxHeight);
                    go.name = "4";
                    go.SetActive(true);
                    break;
                case 5:
                    go.transform.position = pos;
                    currentY += Random.Range(advance.movingVertically.minHeight, advance.movingVertically.maxHeight);
                    go.name = "5";
                    go.SetActive(true);
                    break;
                default:
                    break;
            }
        }

运行程序如下

5.回收Tile

在主相机下建立一个回收池

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2tvdXpodWFuamluZzE4NDk_size_16_color_FFFFFF_t_70][]

在GameManager中添加下面的方法

public GameObject floor;
    public void AddInActiveObjectToPool(GameObject go,ObjectType type)
        {
            go.SetActive(false);
            switch (type)
            {
                case ObjectType.Tile:
                    tilePool.Enqueue(go);
                    //TODO:生成tile
                    break;
                case ObjectType.Item:
                    itemPool.Enqueue(go);
                    break;
                case ObjectType.Coin:
                    coinPool.Enqueue(go);
                    break;
                case ObjectType.Enemy:
                    enemyPool.Enqueue(go);
                    break;
                case ObjectType.Bullet:
                    bulletPool.Enqueue(go);
                    break;
                default:
                    break;
            }
        }

在Tile中进行调用

private void Update()
        {
            if (GameManager.Instance.floor.transform.position.y > transform.position.y + 1)
            {
                GetComponent<Rigidbody2D>().gravityScale = 0f;
                GameManager.Instance.AddInActiveObjectToPool(gameObject, ObjectType.Tile);
            }
        }

运行程序结果如下，下面的tile都被回收

![20181225205750223.png][]

6.砖块水平竖直移动

在Tile脚本中添加代码，让tile可以自己移动

//方块的移动速度和距离
        float speed;
        float distance;
        Vector3 startPos;
        int direction;  //0:left & up 1:right & down 
        void Init()
        {
            sp = GetComponent<SpriteRenderer>();
            tileType = int.Parse(gameObject.name);
            switch (tileType)
            {
                case 0:
                    sp.sprite = sprites[0];
                    break;
                case 1:
                    sp.sprite = sprites[1];
                    break;
                case 2:
                    sp.sprite = sprites[2];
                    break;
                case 3:
                    sp.sprite = sprites[3];
                    break;
                case 4:
                    sp.sprite = sprites[4];
                    speed = GameManager.Instance.advance.movingHorizontally.speed;
                    distance = GameManager.Instance.advance.movingHorizontally.distance;
                    startPos = transform.position;
                    break;
                case 5:
                    sp.sprite = sprites[5];
                    speed = GameManager.Instance.advance.movingVertically.speed;
                    distance = GameManager.Instance.advance.movingVertically.distance;
                    startPos = transform.position;
                    break;
                default:
                    break;
            }
        }
        private void Update()
        {
            switch (tileType)
            {
                case 4:
                    if (direction == 0)
                    {
                        transform.Translate(new Vector2(-speed * Time.deltaTime, 0));
                        if (startPos.x - transform.position.x > distance)
                        {
                            direction = 1;
                        }
                    }
                    else
                    {
                        transform.Translate(new Vector2(speed * Time.deltaTime, 0));
                        if (startPos.x - transform.position.x < -distance)
                        {
                            direction = 0;
                        }
                    }
                    break;
                case 5:
                    if (direction == 0)
                    {
                        transform.Translate(new Vector2(0,-speed * Time.deltaTime));
                        if (startPos.y - transform.position.y > distance)
                        {
                            direction = 1;
                        }
                    }
                    else
                    {
                        transform.Translate(new Vector2(0,speed * Time.deltaTime));
                        if (startPos.y - transform.position.y < -distance)
                        {
                            direction = 0;
                        }
                    }
                    break;
                default:
                    break;
            }
    }

运行结果如下

7.设置游戏状态

在GameManager中添加三种状态并添加游戏结束的代码

public enum GameState
    {
        PAUSED,
        RUNNING,
        GAMEOVER
    }
        //游戏状态
        public GameState gameState = GameState.PAUSED;
        //结束游戏
        public void EndGame()
        {
            if(gameState != GameState.GAMEOVER)
            {
                gameState = GameState.GAMEOVER;
                //TODO:save data UI
            }
        }

在Player脚本中进行调用

private void OnTriggerEnter2D(Collider2D collision)
        {
            if (collision.tag == "Platform")
            {
                Jump(1);
            }
            if(collision.tag == "Floor")
            {
                GameManager.Instance.EndGame();
            }
        }

运行程序结果如下

![20181226141838638.png][]![20181226141856655.png][]

8.无限生成Tile

在GameManager中添加重新生成tile的方法

/// <summary>
        /// 当一个tile销毁时，调用此方法
        /// </summary>
        void CreateTile()
        {
            if(gameState != GameState.GAMEOVER)
            {
                GenerateTile();
                //添加道具
                //难度曲线
                //分数
    
            }
        }

并在砖块销毁的时候进行调用

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2tvdXpodWFuamluZzE4NDk_size_16_color_FFFFFF_t_70 1][]

运行程序结果如下

        }
    
        public void OnTriggerEnter2D(Collider2D collision)
        {
            if (collision.tag == "Player")
            {
                player = collision.gameObject;
                //隐藏
                sp.enabled = false;
                //速度为0
                player.GetComponent<Rigidbody2D>().velocity = Vector2.zero;
                //让重力不影响我们的运动
                player.GetComponent<Rigidbody2D>().isKinematic = true;
                //无敌
                GetComponent<CircleCollider2D>().enabled = false;
                //显示图片
                used[itemType].SetActive(true);
                //fly
                StartCoroutine("StopFly");
            }
        }
    
        IEnumerator StopFly()
