One example of + a wallpaper would be a sheet of standard ruled notebook paper. +* The texture file will be a square (rectangular maybe ok) with four quadrants + from which the textures will be extracted. For example if the overall image + size was 100x100 pixels, it will be divided into the four 50x50 quadrants. + 1. `TL`: Top left corner is the top left edge of the "page" the level is on + 2. `TR`: Top right corner is the repeated "top of page" texture. + 3. `BL`: Bottom left corner is the repeated "left of page" texture. + 4. `BR`: Bottom right corner is the repeated background texture that extends + infinitely in all directions. +* Levels will be able to choose a "page type" which controls how the wallpaper + will be drawn and how the level boundaries may be constrained. There will be + four options: + 1. **Unbounded:** The map can freely grow in any direction, including into the + negative X/Y coordinates. The map author will not run up against a boundary + as the level grows in any direction. + 2. **No Negative Space:** The map coordinates can not dip below `(0,0)`, the + origin at the top-left edge of the map. The map can grow infinitely in the + positive X and Y directions (to the right and down) but is constrained on + the left and right edges. The game engine will stop scrolling the map when + the top or left edges are reached, and those edges will behave like a solid + wall. + 3. **Bounded:** The map has a fixed width and height and is bounded on all + four edges. + 4. **Bounded, Mirrored Wallpaper:** same as Bounded but with a different + wallpaper behavior. +* The page types will have their own behaviors with how wallpapers are drawn: + * **Unbounded:** only the `BR` texture from the wallpaper is used, repeated + infinitely in the X and Y directions. The top-left, top, and left edge + textures are not used. + * **No Negative Space:** the `TL` texture is drawn at coordinate `(0,0)`. + To its right, the `TR` texture is repeated forever in the X direction, and + along the left edge of the page, the `BL` texture is repeated in the Y + direction. The remaining whitespace on the page repeats the `BR` texture + infinitely. + * **Bounded:** same as No Negative Space. + * **Bounded, Mirrored Wallpaper:** same as No Negative Space, but all of the + _other_ corners and edges are textured too, with mirror images of the Top, + Top Left, and Left textures. This would look silly on the "ruled notebook" + texture, but could be useful to emborder the level with a fancy texture. +* The game will come with a few built-in textures for levels to refer to by + name. These textures don't need to be distributed with the map files themselves, + as every copy of the game should include these (or a sensible fallback would + be used). +* The map author can also attach their own custom texture that will be included + inside the map file. + # Text Console * Create a rudimentary dev console for entering text commands in-game.
