# Minetest canvas_game printer

This is a lua script for [hydra-dragonfire](https://bowels-of-the.macrofox.org/git/mtpt/hydra-dragonfire)
that can print a full colour image onto a canvas of a minetest server running [canvas_game](https://links.ofafox.com/out.php?url=https://gitlab.com/Kimapr/canvas_game)

# Dependancies

* hydra-dragonfire
* php-cli
* imagemagick (optional)

# How To Install

These are the steps needed to get this working on Linux. I have not tried doing this on Windows so I can't help with that.

Clone and build [hydra-dragonfire](https://bowels-of-the.macrofox.org/git/mtpt/hydra-dragonfire) per its instructions.

Open a terminal and clone this repo.
`git clone https://bowels-of-the.macrofox.org/git/mtpt/canvas_printer.git`

# How To Use

cd into the directory of the git repo `cd canvas_printer/`

Find the image you want to print. If it is larger than 500 by 500, it will need to be resized. To do this, imagemagick is needed.
Run `./imagefit.sh /path/to/image.png outputname.png`

Use the php script to convert the image into a set of instructions for the minetest bot. `php convert.php /path/to/image-or-output.png`
This will create a file named `inst.txt` which contains the instructions.

Now run `draw.lua` with hydra-dragonfire and set the server info.
`/path/to/hydra-dragonfire ./draw.lua <ip>:<port> <username> [<password>]`

If everything goes to plan, a bot should now join the server and start printing your image onto the canvas. Once it is done, the bot will leave the server.
