批量移动像素的算法?

目前我正在尝试制作一个简单的2D地图生成程序,除了一个关键的东西之外它几乎完成了。生成的岛屿的运动。程序运行的方式让地图中间的所有岛屿都像so一样被颜色分开,就像呕吐物的迪斯科球一样,但我的主要问题是试图将岛屿移动到新的位置。

该计划应该根据颜色随机将岛屿放置在新的地方,但我在这方面遇到了相当大的困难,因为我所尝试的所有解决方案都是在海啸指数中落到了他们的脸上超出阵列范围'错误或有效,但花了几个小时来移动一个岛屿。

TLDR;是否存在任何可能允许我将像素组成的形状移动到随机位置同时保持其现有形状的算法?我很糟糕。

编辑:我会尝试重写这个以便以后更容易阅读,因为我匆忙,但实质上它使用.getpixel读取圆圈中的所有像素并将它们存储在基于它们的数组中颜色,它然后生成一个随机位置并再次运行相同的代码,只是这次它将接受一个颜色作为参数,如果它找到一个相同的颜色将颜色相对于圆的中心放置在像素作为它目前正在接受的颜色。

理论上,这应该贯穿每一种颜色并为每一种颜色创造一个新的位置,以保持岛屿的形状,但在实践中它只需要永远。

                //Thoughts - use the circle generator as a radar to find all the seperate colors, then for each color randomly generate an x and a y. then use the circle generator but only apply the colors that are selected

                if (tempi >= 716 || tempib > 0)
                {
                    if(tempib <= 0)
                    {
                        tempi = 0;
                        tempib = 1;
                        randxb = Rander.Next(10, xlen - 10);
                        randyb = Rander.Next(10, ylen - 10);
                    }

                    tempi += 1;

                    day += 1;
                    if(day >= 31)
                    {
                        month += 1;
                        day = 1;
                    }

                    if(month >= 13)
                    {
                        year += 1;
                        month = 1;
                    }

                    AD = "PF";
                    era = "Prehistoric era";
                    age = "Islandic Age";

                    Point temppb = new Point(randxb, randyb);

                    if (colours[tempib] == Color.DarkBlue || colours[tempib] == Color.FromArgb(0, 0, 0))
                    {
                        tempib += 1;
                    }
                    else
                    {
                        Radar(0, temppb, "write", colours[tempib]);
                    }

                    tempi = 0;
                    tempib += 1;
                    randxb = Rander.Next(10, xlen - 10);
                    randyb = Rander.Next(10, ylen - 10);

                    if (tempib >= islandnuma)
                    {
                        age = "Neanderthalic Age";
                    }
                }
                else
                {
                    year += Rander.Next(1, 3);
                    day = 1;
                    AD = "PF";
                    era = "Prehistoric era";

                    Point tempp = new Point(xlen / 2 - 150, ylen / 2 - 150);
                    tempi += 1;
                    Radar(tempi, tempp, "scan", Color.White);
                    if(tempi >= 716)
                    {
                        clearmap();
                    }
                }

            }

这是它所谓的可怕算法

        Color[,] scanresults = new Color[717, 4499]; //shell, place in shell

        using (var g = Graphics.FromImage(pictureBox1.Image))
