| 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 | ||||
| ======= | ||||
|  | ||||
| 
 | ||||
| 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. | ||||
