问题1，角色移动不正常，有时可以移动，有时不可以移动，有时移动到某些位置后便不能移动。

问题2，角色无法攻击地图内的墙，（没有动画）墙也不会消失

问题3.食物生成位置不正确，有一定几率会生成在外围墙里

一些关键代码：

        //创建障碍物 食物 敌人
        //创建障碍物
        int wallCount = Random.Range(minCountWall, maxCountWall + 1);//障碍物的个数
        InstantiateItems(wallCount,wallArray);
        //创建食物 2 - level*2
        int foodCount = Random.Range(2, gameManager.level*2 + 1);
        InstantiateItems(foodCount,foodArray);

        //创建敌人 // level/2
        int enemyCount = gameManager.level/2;
        InstantiateItems(enemyCount,enemyArray);
        //创建出口
        GameObject go4 = Instantiate(exitPrefab, new Vector2(cols - 2, rows - 2), Quaternion.identity) as GameObject;
        go4.transform.SetParent(mapHolder);

private void InstantiateItems(int count, GameObject[] prefabs) {
        for (int i = 0; i < count; i++)
        {
            Vector2 pos = RandomPosition();
            GameObject enemyPrefab = RandomPrefab(prefabs);
            GameObject go = Instantiate(enemyPrefab, pos, Quaternion.identity) as GameObject;
            go.transform.SetParent(mapHolder);
        }
    }
    private Vector2 RandomPosition() {
        int positionIndex = Random.Range(0, positionList.Count);
        Vector2 pos = positionList[positionIndex];
        positionList.RemoveAt(positionIndex);
        return pos;
    }

    private GameObject RandomPrefab(GameObject[] prefabs) {
        int index = Random.Range(0, prefabs.Length);
        return prefabs[index];
    }
}
