Question

I need help with my map editor, I’m stuck on saving it. When I save, after I put some grass on map, it gets grass everywhere in map file.
Here’s variables:

mapMaximumX: maximum of the map in X (it is set as 500)

mapMaximumY: maximum of the map in Y (it is also set as 500)

mapTiles[index]: this is a list with class, each class has ID (0 = empty, 1 = grass, 2 = water), X and Y

        if (Keyboard.GetState().IsKeyDown(Keys.F1))
        {
            for(int y = 0; y < mapMaximumY; y++) 
            {
                for (int x = 0; x < mapMaximumX; x++)
                {

                    if (MapTiles[i3].X == x && MapTiles[i3].Y == y)
                    {

                    }

                    else
                    {
                        MapTiles.Add(new Class1(0, x * 32, y * 32));
                    }

                    if (i3 < MapTiles.Count)
                    {
                        i3++;
                    }
                }
            }

            TextWriter file = new StreamWriter("map1.MAP");
            for (int y = 0; y < mapMaximumY; y++)
            {
                for (int x = 0; x < mapMaximumX; x++)
                {
                    file.Write(MapTiles[i2].ID + ", ");
                }
                file.Write(file.NewLine);
            }
            i2 = 0;
            System.Windows.Forms.MessageBox.Show("Saved!");
            file.Close();
        }

Full code is here, if u need it:

Thanx.

Answer 1

file.Write(MapTiles[i2].ID + ", ");

i2 never changes within your loop, so whatever i2 is will always be what’s used to write your output.

You need to be using X and Y from your loops in determining which cell to write out.
