Releasing a Mod default ../

Introduction

In this chapter we will find out how to publish a mod so that other users can use it.

  • License Choices
  • Packaging
  • Uploading
  • Forum Topic

Before you release your mod, there are some things to think about:

  • Is there another mod that does the same thing? If so, how does yours differ or improve on it?
  • Is your mod useful?

License Choices

You need to specify a license for your mod. Public domain is not a valid licence, as the definition varies in different countries.

First thing you need to note is that your code and your art need different types of protection.

You are allowed any license, however mods which disallow derivatives are banned from the forum. (Other developers must be able to take your mod, modify it, and release it again.)

LGPL and CC-BY-SA

This is a common license combination in the Minetest community, as it is what Minetest and minetest_game use. You license your code under LGPL 2.1 and your art under CC-BY-SA.

  • If someone modifies your mod, they must give their version the same license
  • Your copyright notice must be kept.

Add this copyright notice to your README.txt, or as a new file called LICENSE.txt

---------------------------------------

CC-BY-SA 3.0 UNPORTED. Created by Your Name

WTFPL or CC0

These licenses allows anyone to do what they want with your mod. Modify, redistribute, sell, leave out attribution. They can be used for both code and art.

Packaging

There are some files that we recommend you include in your mod when you release it.

README.txt

You should provide a readme file. This should state:

  • What the mod does.
  • What the license is.
  • Current version of mod.
  • How to install the mod.
  • What dependencies there are / what the user needs to install.
  • Where to report problems/bugs or get help.

Example:

My Super Special Mod
====================

Adds magic, rainbows and other special things.

Version: 1.1
Licence: LGPL 2.1 or later

Dependencies: default mod (found in minetest_game)

Report bugs or request help on the forum topic.

Installation
------------

Unzip the archive, rename the folder to to modfoldername and
place it in minetest/mods/minetest/

(  Linux: If you have a linux system-wide installation place
	it in ~/.minetest/mods/minetest/.  )

(  If you only want this to be used in a single world, place
	the folder in worldmods/ in your worlddirectory.  )

For further information or help see:
http://wiki.minetest.com/wiki/Installing_Mods

description.txt

Write a sentence or two explaining what your mod does. Be concise without being too vague. This is displayed in the mod store.

For example:

GOOD: Adds soups, cakes, bakes and juices. The food mod which supports the most ingredients.
BAD:  The food mod for Minetest.

Screenshots should have 4 pixels of width for every 3 pixels of height, and be at least 200 by 150. This is displayed in the mod store.

Uploading

In order for a potential user to download your mod, you need to upload it to somewhere which is publically accessible.\ I will outline several methods you can use, but really you should use the one that works best for you, as long as it mets these requirements:\ (and any other requirements which may be added by forum moderators)

  • Stable - the hosting website should not just shutdown randomly.
  • Direct link - you should be able to click a link on the forum and download the file, without having to view another page.
  • Virus Free - pretty obvious.

Github, or another VCS

It is recommended that you use Version Control System for the following reasons:

  • Allows other developers to submit changes (easily).
  • Allows the code to be previewed before downloading.
  • Allows users to submit bug reports.

However, such systems may be hard to understand when you first start out.

The majority of Minetest developers use Github as a website to host their code, however that doesn't matter that much.

Forum Attachments

You could use forum attachments instead. This is done when creating a mod's topic - covered below.

First, you need to zip the files into a single file. This varies from operating system to operating system.

On Windows, go to the mod's folder. Select all the files. Right click, Send To > Compressed (zipped) folder. Rename the resulting zip file to the name of your modfolder.

On the create a topic page, see below, go to the "Upload Attachment" tab at the bottom. Click browse and select the zipped file. I suggest that you enter the version of your mod in the comment field.

Upload Attachment
Upload Attachment tab.

Forum Topic

You can now create a forum topic. You should create it in the "WIP Mods" (Work In Progress) forum.\ When you consider your mod no longer a work in progress, you can request that it be moved to "Mod Releases."

Content

The requirements of a forum topic are mostly the same as what is recommended for a README.txt

  • What the mod does.
  • What the license is.
  • Current version of mod.
  • How to install the mod.
  • What dependencies there are.
  • Where to report problems/bugs or get help.
  • Link to download, or an attachment.

You should also include screenshots of your mod in action, if relevant.

Here is an example. The Minetest forum uses bbcode for formating.

Adds magic, rainbows and other special things.

See download attached.

[b]Version:[/b] 1.1
[b]Licence:[/b] LGPL 2.1 or later

Report bugs or request help on the forum topic.

[h]Installation[/h]

Unzip the archive, rename the folder to to modfoldername and
place it in minetest/mods/minetest/

(  Linux: If you have a linux system-wide installation place
	it in ~/.minetest/mods/minetest/.  )

(  If you only want this to be used in a single world, place
	the folder in worldmods/ in your worlddirectory.  )

If you modify the above example for your mod topic, remember to change "modfldername" to the name of the folder your mod should be in.

Title

Subject of topic must be in one of these formats:

  • [Mod] Mod Title [modname]
  • [Mod] Mod Title [version number] [modname]
  • eg: [Mod] More Blox [0.1] [moreblox]
