Router Tetris

When I was writing some scripts for my asus routers, I suddenly wanted to try if I could play games on the router, so I tried to find some games written in shell scripts, at first I wanted to try The Game of Life, But the CPUs usage is always 100% due to many calculations, I ended up going with Tetris, after trying a few I decided to fork @ContentsViewer's shtris and make compatibility improvements.

The main changes I made are:

Because the sleep provided by busybox does not support floating point numbers, use usleep instead.

Changed thespecial character for GHOST_CELL to ensure better compatibility.

Usage

# go to the temporary directory (this game will be deleted after restarting the router)
cd /tmp

# download
wget https://raw.githubusercontent.com/l11/router-tetris/main/shtris -O ./shtris

# add permissions
chmod +x ./shtris

# run it
sh ./shtris

Show Help

$ ./shtris -h
Usage: shtris [options]

Options:
 -d, --debug          debug mode
 -l, --level <LEVEL>  game level (default=1). range from 1 to 15
 --rotation <MODE>    use 'Super' or 'Classic' rotation system
                      MODE can be 'super'(default) or 'classic'
 --lockdown <RULE>    Three rulesets —Infinite Placement, Extended, and Classic—
                      dictate the conditions for Lock Down.
                      RULE can be 'extended'(default), 'infinite', 'classic'
 --seed <SEED>        random seed to determine the order of Tetriminos.
                      range from 1 to 4294967295.
 --no-color           don't display colors
 --no-beep            disable beep
 --hide-help          don't show help on start
 -h, --help     display this help and exit
 -V, --version  output version infromation and exit
 
Version:
 3.0.0

Supported Environments

Environment	Support
Asuswrt 386.x and higher (sh by busybox)	o
Asuswrt-Merlin 386.x and higher (sh by busybox)	o
Fresh Tomato 2022 (sh by busybox)	o (Not fully tested)

Notice

I did testing on an RT-AC86U running 386.5_2 (this is a cortex-a53 router with dual core 1.8GHz) but the CPUs usage is still over 80% in play and stutters as the difficulty level of the game increases will be more serious.

So, this is just a test of whether the router CPUs can handle a simple game, enjoy it or not.

This fork is designed to be compatible with specific platforms, and as a proof of concept for running games on routers, it may not be actively maintained in the future, any issues in the original code should be submitted directly to the original project, and any comments about this project should be in the discussion.
