Question

好的，所以我正在尝试显示一个瓷砖地图，但我的数学似乎已经关闭了。

private void MapPanel_Paint(object sender, PaintEventArgs e)
        {
            Graphics g = e.Graphics;
            GraphicsUnit units = GraphicsUnit.Pixel;

            for (int i = 0; i < map.tiles.Length; i++)
            {
                for (int j = 0; j < map.tiles[i].Length; j++)
                {
                    int tileXCoord = 0;
                    int tileYCoord = 0;
                    int tileSheetWidth = tileMap.Width / map.tileSize;

                    if (map.tiles[i][j] != 0)
                    {
                        tileXCoord = tileSheetWidth % map.tiles[i][j];
                        tileYCoord = tileSheetWidth / map.tiles[i][j];
                    }

                    Rectangle destRect = new Rectangle((i * map.tileSize) - hScrollValue, (j * map.tileSize) - vScrollValue, map.tileSize, map.tileSize);
                    g.DrawImage(tileMap, destRect, tileXCoord * map.tileSize, tileYCoord * map.tileSize, map.tileSize, map.tileSize, units);
                }
            }
        }

现在我正在尝试让我的地图使用“自动换行”磁贴索引

[0][1]
[2][3]

但它没有用，有人知道为什么吗？

Answer 1

我用

tileXCoord = ((currentTile % tilesize) * Imagewidth);
tileYCoord = ((currentTile / tileSize) * Imagewidth);

哪种方式适合我。请注意，我绝不是这类事情的专家。

private void MapPanel_Paint(object sender, PaintEventArgs e)
        {
            Graphics g = e.Graphics;
            GraphicsUnit units = GraphicsUnit.Pixel;

            for (int i = 0; i < map.tiles.Length; i++)
            {
                for (int j = 0; j < map.tiles[i].Length; j++)
                {
                    int tileXCoord = 0;
                    int tileYCoord = 0;
                    int tileSheetWidth = tileMap.Width / map.tileSize;

                    if (map.tiles[i][j] != 0)
                    {
                        tileXCoord = map.tiles[i][j] % tileSheetWidth;
                        tileYCoord = map.tiles[i][j] / tileSheetWidth;
                    }

                    Rectangle destRect = new Rectangle((i * map.tileSize) - hScrollValue, (j * map.tileSize) - vScrollValue, map.tileSize, map.tileSize);
                    g.DrawImage(tileMap, destRect, tileXCoord * map.tileSize, tileYCoord * map.tileSize, map.tileSize, map.tileSize, units);
                }
            }
        }

正确显示简单的瓷砖地图？
