原理利用2D游戏为了实现寻路而创建的二维数组去生成一张Texture2D纹理图大地图是直接用int[,]map二维数组去创建map[x,y]等于1是空地不等于1是障碍物或不可穿越地形 大地图上的玩家绿点是直接拿到玩家在map的坐标点直接绘制。
小地图是以玩家为中心的[-smallSize/2, smallSize/2]范围内进行绘制小地图上的玩家绿点是直接绘制到中心点(smallSize.x/2, smallSize.y/2)
注意绘制到Texture2D的像素点坐标是[0, size]范围的则小地图的绘制是SetPixel(i, j, color)传递i, j是[0,size]范围的而不要传递x, y这个x,y的取值是以玩家点为中心的[-size/2, size/2]范围坐标值如下取法
x 玩家点.x - size.x/2 i; y 玩家点.y - size.y/2 j;
用2层for遍历来看的话就是从(玩家点.x - size.x/2, 玩家点.y - size.y/2)坐标点从下往上从左往右依次遍历每个map[x,y]点生成对应颜色的像素点构成一张Texture2D图片。 using System.Collections;

}小地图2张Image图片的材质球要使用不同的材质球实例 四、GameLogicMap脚本修改
主要变化新增和修改
初始化绘制大地图和小地图 smallMapFor2D.InitBigMap(map, new Vector2Int(map.GetLength(0), map.GetLength(1))); DrawSmallMap();
A*寻路方法返回路径数组这是一个从终点到起点的数组所以使用时是倒序遍历的。 public ListVector3Int PlayAstar(Vector3Int endPos)
