Default layout but with a tetris game | |||
===================================== | |||
Tetris works by outputting key-presses to make ascii-art in a regular text editor. | |||
It reads key presses to rotate and move the bricks like a regular tetris game. | |||
Example | |||
======= | |||
![tetris](https://raw.githubusercontent.com/danamlund/meckb_tetris/master/tetris.gif) | |||
Usage | |||
===== | |||
1) Open a default text editor | |||
2) Press the tetris button (Fn + t) | |||
3) Play tetris | |||
It makes ascii-art by sending keycodes: left, right, up, down, qwerty characters, and numbers. | |||
Problems | |||
======== | |||
Drawing ascii-art is too slow to make a pleasant playing experience. | |||
While drawing ascii-art, the keyboard does not record key-presses, so its pretty unresponsive. | |||
Adds 5000 bytes to the hex file. | |||
Implement in other keyboards | |||
============================ | |||
- Copy-paste the files tetris_text.c and tetrix_text.h to your keymap folder. | |||
- Add/update your-keyboard/your-keymap/Makefile to include ``SRC = tetris_text.c`` | |||
- Copy-paste the tetris-related code from this keymap.c to yours. | |||
- Set a key to trigger F(1) to start tetris mode. | |||
- Its also a good idea to set a key to stop tetris, here its escape. | |||
