40d:Custom grid

Version 0.28.181.39f introduced the ability to increase the grid from 80 tiles wide by 25 tiles high to as many as 200 by 200. The resolution and font are still a critical concern and must be calculated to match, to avoid strange results and crushed fonts.

To work out what grid size you want for a given screen resolution and font tile size:

1. Determine your tile size. This may be found by dividing the x value of the intended screen resolution of the font by the x value of the grid, and then the y values are divided by each other. Example: If we use the default grid size, 80:25, and the resolution of curses_800x600.bmp, 800x600, then we would divide 800 by 80 to get 10 and 600 by 25 to get 24. This means our tiles are each 10x24.
2. Divide the x value of your screen resolution by the x value of the tile size to determine your wanted x grid value, then do the same with the y values to determine your y grid value.
3. Change the [GRID] entry in the init.txt file to reflect your changes.

• Note: if your font is, for example, a 16x16 font, as specified in the filename, this means that each tile is intended to be 16x16 pixels in size, and you may therefore avoid the mathematics in step 1

Notes

• The title screen will be situated in the top right of the screen, instead of centred.
• It is impossible to set different grid values for fullscreen and windowed, it is unknown whether this will be implemented in future versions.
• Setting [TEXTURE_PARAM:LINEAR] instead of [TEXTURE_PARAM:NEAREST] will make squished tiles better looking.

Notable Combinations

• [FULLSCREENX:1600], [FULLSCREENY:1200], [FONT:curses_640x300.bmp], [GRID:200:100] (640x300 is 8x12 per tile)
• [FULLSCREENX:1920], [FULLSCREENY:1200], [FONT:curses_800x600.bmp], [GRID:192:100] (800x600 utilized at 10x12 per tile, for an almost square aspect ratio with lots of view space)
• [FULLSCREENX:1680], [FULLSCREENY:1050], [FONT:{any 16x16 font}], [GRID:105:65]
