1 # VIIper - a Snake Clone for Unicode-compatible Terminals
5 - A VTE based terminal (like GNOME Terminal and a whole bunch of others)
6 - Google Noto's Color Emoji Font (Fedora: `google-noto-emoji-color-fonts.noarch`)
10 hjkl or cursor keys move the snake.
11 r to restart, p to pause, q to quit.
15 - DONE base game: fixed field size, fixed speed
17 - put 'sprites' into `schemes.h`
20 - timer, score, increasing speed
21 - special items: slower snake, shorter snake, etc.
22 - input buffer (so fast 180° turns get executed)
28 to display emojis, we need a terminal that can handle a color emoji font (no
29 shit, sherlock). mlterm, xterm and urxvt didn't work in my tests (mlterm might
30 work if compiled correctly, the other two use bitmap fonts and i don't think
31 there are any w/ emoji support). konsole will have to be tested in the future.
32 i intend to put bonus items in the game that will only be visible for a short
33 time. when they get near the end of their life, SGI-5 (blink) will make them
34 blink. this is supported in gnome-term 3.28 (vte 0.52) which is supplied with
35 fedora 28. [bug report](https://bugzilla.gnome.org/show_bug.cgi?id=579964)
39 to draw the snake with box chars, we need to know which glyph to draw.
41 our current position is X, and our predecessor and successor are on one of
42 `[NESW]` of us (we need to compute the relpos from the absolute). we need to
43 draw a line between them. note that head and tail have `NULL` as pre-/successor.
