This script generates a two-step theme for Plymouth that shows a randomly chosen Pokemon jumping until the boot process is finished.

Icons are from oakdex-pokedex-sprites.

$ git clone https://github.com/realChesta/plymouth-pokemon.git
$ cd plymouth-pokemon
$ sudo sh pokemon-generator

(pokemon-generator has to be run with elevated privileges.)

Use pokemon-generator -u to automatically copy the generated theme into the themes directory and update the plymouth configuration.

The option -k instructs the script to keep the temporarily created resized pokemon image ($TEMP_IMG).

The option -p makes the script keep a pokenum-prev.txt file containing the number of the previousy generated Pokemon.

Run pokemon-generator -u once per boot and enjoy a new Pokemon every time you boot!

There are multiple variables in the script that can easily be adjusted to tweak its functionality:

• PICK_RANGE is the range of National PokeDex numbers to be included in the Pokemon selection.
• ICON_LOCATION determines where the the folder containing the icons is located.
• ANIMATION_LENGTH sets how many frames the animation should contain.
• JUMP_HEIGHT is the jump height in pixels (the canvas is 256x256)
• DOUBLE_FINISH_ANIMATION if this is set to true, the pokemon will jump twice before booting is completed (as opposed to once)
