Question

所以我有一个程序生成的游戏，加载成块，我需要一种方法让我的代码记住，如果我砍下一棵树或打破一块岩石，所以它不会取代它离开和进入一个新的区域。我得到它几乎工作，除了不将它们放回正确的位置，它移动它们填补空白。（如果是这样的话）

这是将删除的瓷砖添加到我移除的瓷砖阵列中的简洁功能

    public function removeAndAddTile(tileRemoved:Function, tileAdded:Function, i:int)
    {

        world.removedTiles.push(world.tilesInWorld[i]);

    }

这是在进入区域后放置瓷砖后加载的内容。换句话说，什么是假设要替换已被销毁的瓷砖

    protected function usedTiles()
    {
        for (var i:int = world.tilesInWorld.length - 1; i >= 0; --i)
        {
            for (var c:int = world.removedTiles.length - 1; c >= 0; --c)
            {
                if (world.tilesInWorld[i].x == world.removedTiles[c].x && world.tilesInWorld[i].y == world.removedTiles[c].y)
                {
                    var ti:String = world.tilesInWorld[i].onTile;
                    var tx:int = world.removedTiles[c].x;
                    var ty:int = world.removedTiles[c].y;
                    world.worldTiles.removeChild(world.tilesInWorld[i]);
                    switch (ti)
                    {
                        case "grass" :
                            world.tilePool.returnSprite(world.tilesInWorld[i]);
                            break;
                        case "stone" :
                            world.rockPool.returnSprite(world.tilesInWorld[i]);
                            break;
                    }
                    world.tilesInWorld.splice(i, 1);
                    clicked = true;
                    switch (ti)
                    {
                        case "grass" :
                            world.tile = world.tilePool.getSprite();
                            break;
                        case "stone" :
                            world.tile = world.stonePool.getSprite();
                            break;
                    }
                    world.tile.width = world.TILE_SIZE;
                    world.tile.height = world.TILE_SIZE;
                    world.tile.x = tx;
                    world.tile.y = ty;
                    world.tilesInWorld.push(world.tile);
                    world.worldTiles.addChildAt(world.tile, i);
                }
            }
        }
    }

我的问题很简单，我怎样才能让我的瓷砖在被销毁时记住，并在进入某个区域时删除并更换这些瓷砖？

您可以使用两个图层。地图表面的一个底层，另一个细节层包含树木，岩石。当你的角色移动并出现新的区域图块时，尝试获取新区域图块数据并将树木，岩石添加到新图块位置。

//the key may be tileX_tileY, the value will be the object type
//if a rock or a tree been broke,delete detailDic[tileX_tileY]
var detailDic:Dictionary;

当您的角色移动并进入新区域时

var newTiles:Array;//the new appeared tiles

for each (var tile:Tile in newTiles)
{
    var key:String = tile.tileX + "_" + tile.tileY;

    var objectType:String = detailDic[key];

    if (check ojectType is valid)
    {
       add the wanted tree, rock to target position.
    }
}

//here you should remove the trees and rocks that disappear from your map's ViewPort

我怎么能删除一些瓷砖？
