@ -27,14 +27,25 @@ OPTIONS:
-s <SPEED> Set the speed, from 1 to 10. (default 5)
-r <RADIUS> Set the radius of the metaballs, from 1 to 10. (default: 5)
-R <RIM> Set a rim for each metaball, sizes from 1 to 5.(default: none)
This option does not work with the default color.
This option does not work with the default color
If you use Kitty or Alacritty you must use it with the -k option to see the rim.
-k <COLOR> Set the color of the rim if there is one. Available colours: red, blue, yellow, green, cyan and magenta.
-b <NBALLS> Set the number of metaballs in the simulation, from 2 to 20. (default: 10)
-b <NBALLS> Set the number of metaballs in the simulation, from 5 to 20. (default: 10)
Increase or decrease the number of balls in runtime with the m and l keys.
-F <CHARS> Allows for a custom set of chars to be used
Only ascii symbols are supported for now, wide/unicode characters may appear broken.
Only ascii symbols are supported for now, wide/unicode chars may appear broken.
-C Retain the entire lava inside the terminal.
It may not work well with a lot of balls or with a bigger radius than the default one.
-h Print help.
RUNTIME CONTROLS:
i Icrease radius of the metaballs.
d Decrease radius of the metaballs.
shift i Icrease rim of the metaballs.
shift d Decrease rim of the metaballs.
m Icrease the number of metaballs.
l Decrease the number metaballs.
+ Icrease speed.
- Decrease speed.
```
