I encourage other people to look at other styles and methods too. It’s good to learn the shortcuts and things that people do.
Okay, I’ll explain a bit about dithering and tiling. I’ll show you how this relates to walls soon.
Since I started with coloring, I’ll continue on with that before I go into tiling. Dithering is a way of blending 2 colors together without using a 3rd color. The most common type is a checkerboard pattern of pixels. It can also help to create some texture. However, do not overdo dithering!
Here are some dithering examples. You have a Red color and a Blue color. Instead of making a Purple color, I’ll make a checkerboard pattern with both of them to make a Purple looking box. Also, I made some dithering between the blue and the red in the bottom to kinda blend them together without using another color.
You don’t need to use checkerboard patterns for dithering either. Here are some other examples, and there are plenty more which you can do.
Tiling is very important for chipsets. You don’t want your grass to look boxy, and you would want bricks to look right. I like making a 16×16 tile, then using a 32×32 square, and placing 4 tiles in it to see how it tiles. You can also subdivide the grid, so you can work with 8×8 squares, or 4×4 or even smaller. Test it out, see which one of these 2 tiles correctly, and which one doesn’t:
Remember, each tile has 16 pixel height and width. So if you divide a tile by 3, you’ll get 5 pixels, 5 pixels, and 6 pixels, so you’ll want to be careful with that. Also, be aware of the edges. That’s frequently where you’ll have to make sure it tiles from. Try not to outline the whole thing, because then it looks boxy, and when you tile them, the lines will be 2 pixels thick rather than 1. For reference, NES games and Gameboy games rely on tiles, because they can’t do it from shades. They are good to learn from, so I suggest you check them out! Try not to make the floor tiles and the wall tiles look the same. Either make the wall tiles bigger than the floor tiles, or the floor tiles bigger than the wall tiles. If not, it’ll just look like a recolored floor.
Walls will usually go from light (on top) to dark (on the bottom). They may also have a base which you may want to include. Here’s a simple example wall. Flat light color on top so I can increase the height to however amount I want it to be. Then, the middle is a blending from light to dark. The bottom is the base. Unless you want all the walls to be the same height, you’ll want one tile of it to tile correctly vertically. And the wall should tile horizontally as well. You might want to vary the shadows, so it’s not just in a straight line. Be sure to check to see if it tiles correctly!
I didn’t get to draw them, but you may want edges for the walls too. This can be in the form of columns, straight lines, or another pattern at the edges of them so the wall doesn’t just cut off.
Some wall tiles I’ve done in the past: (These are for Excalistia, so please don’t use them in your project!)
