Creating your own Tileset

Deciding on size

The character tileset is always arranged in 16x16 tiles but their size is variable. So the first decision you have to make when creating a new tileset is deciding on the tile size: Bigger tiles allow you to draw more details, but you will be able to see less of them at the same time. Non-square tilesets have tiles that are taller than they are wide. The text in these tilesets is generally easier to read, but the map appears squished horizontally. Square tilesets usually provide more attractive graphics, but are slightly less readable without enabling TrueType. More information about size is on the tileset and custom grid pages. Less important points to consider are subdivisions, even/uneven numbers, and popularity. Especially the first two have very little effect, but they're listed for completeness.

Subdivisions

For example, a 10x10px wide tile is divisible by 2/5; 16 by 2/4/8; 18 by 3/6/9. In practice, this could have an effect on tiles where you plan to use multiple subdivisions in symmetry. On a 10x10 tileset, you can't have a checkered floor tile with 9 symmetric small squares; on a 18x18 tileset, you can. If you want them to have a border, the calculations change.

Even/uneven numbers

Tiles with uneven dimensions (9x9, 15x15) have a center pixel. Some tiles benefit from some sort of center point (maybe a gear assembly), and on small tile sizes, a 2x2 center simply would be too thick. So you need to decide between circular symmetry and linear symmetry.

Popularity

Square tilesets - especially 16x16 - are the most popular choice amongst users. Even if you just use the tileset for yourself, you might want to use it together with existing creature graphics, which mostly exist for 16x16 tilesets. While not strictly necessary, it is recommended to use the same tile size for the tileset and creature graphics.

Choosing a base tileset

It's a lot easier to start with an existing tileset than to start with a blank file. You have something to go from and have an overview of the rough look of the original tile. You might not want to change every tile anyway. Obviously you should choose one that has the same tile size as you plan on using; A tileset that already looks close to

Editing a tileset

This tutorial is a step-by-step guide on changing a few tiles from a tileset, saving it, and setting DF to use it. It should contain everything a user without previous experience needs for basic tileset editing. We will be using curses_square_16x16.bmp (a stretched variant of the default tileset) as a base tileset. The instructions apply to Photoshop CS5, but should work with all recent versions of Photoshop and possibly with small differences in GIMP and other bitmap editing programs. You will only need to use a small amount of features: Layers and groups, transparency and masks, and some basic tools (pen, eraser, selection tool). So any program that allows you to use layers, alpha transparency, and can save .png files with transparency should be completely sufficient.

Opening and preparing the base tileset

You should download the newest version of DF and install it in a separate folder. Try to create a typical fortress to see how your new tileset will look in the most common situations

For the purpose of teaching it properly, some steps might seem unnecessary complicated for the scope of the changes in this tutorial. See graphics#good practices below

Open your bitmap editor and load the file "curses_square_16x16.bmp". You will find it in your DF folder in data/art.

• First, make sure you see the following panels: Layers, channels, tools. If not, you can open them in the menu bar under "Window".
• press ctrl+k (or navigate to edit>preferences>general) and click on "guides grids & slices" on the left. Under "grid" set the value for "Gridline Every" to your tile size. In our case, 16 and press OK. You still need to press ctrl+' to make it visible. You should now see a yellow grid on the tile borders.

Our new tileset will be a .png with alpha transparency, so we will have to get rid of the magenta background.

• Right click on the "Background" layer in the layer panel and select "Make layer from background..."
• use the Wand tool (w) and click anywhere on the magenta color; make sure "continuous" and "anti-aliasing" are unchecked in the top bar. Then, press del on the keyboard.
• right click on it, select layer properties and rename it to "base tileset". In big, complicated files, organizing your layers is crucial. Name them appropriately. If you have lots of layers, try to organize them into groups.
• with the layer still selected, press on the "add layer mask" button (bottom of the layers panel, grey square with white circle inside).A layer mask hides pixels of a layer everywhere it's black. White areas are visible. you can draw directly on it like any normal layer by selecting it. Make sure to select the one you want to edit, layer or its mask. You can make it visible in the channel panel, or by pressing '\'

We will use it to mask any of the original tiles we change.

Drawing a white tileset is a lot easier looking at a darker background instead of a checkered greyish white., but we will be using a helper layer instead that won't be visible in the final version. You can also change the background color under preferences>transparancy (ctrl+k). If you only use the program to draw DF tilesets, you might want to use that instead.

• make a new layer (shift+ctrl+n or the button next to the trash can at the bottom of the layers panel)
• verify that you selected the new layer and that your foreground color is black (D to switch to default colors); press alt+del
• move the layer of the background by dragging it down on the layers panel
• Rename it to Black background. Give it another color to differentiate it from other layers.
• Now we only need a new layer for the changes we plan to make. Ctrl+shift+n, move it on top, and call it "new"

This concludes our preparations. Save the file as .psd in your project folder (ctrl+s). We will now add eyebrows to the dwarf tile (tile #1, second tile in first row) and draw a new bed. Finally we will copy the walls of another tileset and use them in ours.

• make sure the base tileset layer is selected. Use the marquee tool (m) to select the dwarf tile; right click on the selection and click on "Layer from copy"
• Select the dwarf again, this time while selecting the mask of the base tileset and press alt+del (make sure your foreground color is black)
• verify the tile is invisible by toggling visibility of "Layer 1"
• Select the Layer with the dwarf on it and draw eyebrows with the pen (n) in white. You can change the tool size right below the menu bar (tool bar).
• Select the eraser tool and set the mode to "pencil" in the tool bar. Give the dwarf a shave and erase some pixels from his beard.

Once you're happy with the outcome, select both, "layer 1" and "new". Merge them with ctrl+e and save your document.

Next we'll draw a new bed.

• Select the base tileset mask again, and with the pen, draw directly (in black) on the bed to make it invisible. We won't be copying the bed to a new layer because it will be completely different.
• Back to layer "new" and start drawing a bed in white.For quick drawing, it's often faster to switch between black and white (x to toggle background/foreground color) instead of switching to the eraser and back to the pen.

If you choose to do that, make the black background layer invisible once you're done and delete all the black pixels at the end.

We'll now manually merge two tilesets by adding the walls from another one.

• download a 16x16 tileset from the repository and open it in photoshop (keep your new tileset open, too).
• Right click on the background layer and "duplicate layer" into your new tileset file.
• go back to your tileset, rename the layer to "walls" and select the walls with a marquee. holding shift lets you select additional areas, holding alt lets you subtract areas
• Select the new layer and, with the marquee selection still active, add a mask. If you chose a tileset with magenta background, remove it as shown above.

Now we want to mask the exact same tiles on the base layer

• ctrl click on the mask of the "walls" layer to select visible pixels
• with the marquee selection active, select the mask of "base tileset" and press alt+del (with black as foreground color)

Save your document again. At this point we're done with our changes and want to export the image.

• Make the black background invisible and go to File>Save for web&devices...
• on the top right, set the file type to PNG-24 and make sure transparency is ticked
• press save and give it a fancy name

stuff to change on tileset page once everything's in place

• clarify graphic set, character set, tileset in first part
• move/change graphic set stuff to graphic set page, add link?
• main creature tiles section: add something like "for a list with raw names see {here|link to graphic set#table}"
• still necessary/useful with graphic set page in place? remove it altogether? Discuss with King Mir
• others should definitely stay, they can't be changed with graphic sets.
