经典小游戏开发思路和算法之推箱子(2) 桃扇骨 2022-03-29 04:10 328阅读 0赞 **游戏简介**：推箱子是一个超经典的游戏，目的是锻炼玩家的逻辑思考能力。 **游戏规则**：这个游戏是在一个正方形的棋盘上进行的，每一个方块表示一个地板或一面墙。地板可以通过，墙面不可以通过。地板上放置了箱子，一些地板被标记为储存位置。玩家被限定在棋盘上，可以水平或垂直移动到空的方块上（不会穿过墙或箱子）。箱子不得被推入其他箱子或墙壁，也不能被拉出。箱子的数量等于储存位置的数量。当所有箱子都被安放到储存地点时，游戏胜利。 **开发思路**：首先是生成地图，用二维数组来储存地图信息，每个元素用不同的数字来标记不同的对象。(例如：0表示空白，1表示墙，2表示角色，3表示箱子，9表示终点(中间空余的值是为了方便添加其他颜色的箱子等))。 地图的生成：通过遍历地图二维数组，读取每个元素的数值，根据数值标记生成不同的地图对象。也可用一维数组表示，其二维数组映射到一维数组的公式为： b\[i*n+j\]==a\[i\]\[j\].其中，设数组有m行n列，i，j分别表示数组内的行数和列数（0<i<m,o<j<n）. 角色移动：使角色在9*9的一位数组中移动，其中左上角为原点。 箱子移动：与角色移动相同。 **游戏实现**： 代码如下： using System.Collections; using System.Collections.Generic; using UnityEngine; public class Done_Build : MonoBehaviour { public static int[] temp_map; public int[] final_map; public GameObject[] destoryObj; public Sprite[] mapSprites; public bool playerDestory = false; public bool boxDestory = false; GameObject g; public GameObject mapPrefab;//地图的墙壁 public GameObject playerPrefab;//角色 public GameObject boxPrefab;//箱子 public GameObject finalBoxPrefab;//到终点后的箱子 public GameObject finalPrefab;//游戏获胜后刷新一张图片，用于提示游戏获胜。 /// <summary> /// 数组初始化 /// </summary> private void Awake() { final_map = new int[9 * 9];//传值数组 temp_map = new int[] { 1, 1, 1, 1, 1, 0, 0, 0, 0, 1, 2, 0, 0, 1, 0, 0, 0, 0, 1, 0, 3, 0, 1, 0, 1, 1, 1, 1, 0, 3, 0, 1, 0, 1, 9, 1, 1, 1, 1, 3, 1, 1, 1, 9, 1, 0, 1, 1, 0, 0, 0, 0, 9, 1, 0, 1, 0, 0, 0, 1, 0, 0, 1, 0, 1, 0, 0, 0, 1, 1, 1, 1, 0, 1, 1, 1, 1, 1, 0, 0, 0 };
