Data Pack Creation

To submit a module to Gamemode 4, it must follow some specific standards. The following instructions will guide you through creating and submitting a module to Gamemode 4. Submitting a module can be done through GitHub.

The following information is taken from the Gamemode 4 Dev GitHub page

Adding a GM4 Module that isn't in the repo yet

• Create a fork of GM4_Datapacks using the Fork button in the top-right of the repo. You will then have a personal copy of the repo ready for your changes.
• Make a copy of the GM4_template_pack folder and rename it to the name of the module you are writing code for.
• Each module you create should be made under a separate branch so that modules can be submitted, approved and tested individually.

Inside the gm4_template_pack folder is code that matches the Gamemode 4 module standard including a copy of the current clocking system. Rename the _pack.mcmeta file to pack.mcmeta. The contents of the file can remain unchanged.

There are several placeholder values in both file names and the files themselves.

• MODULE_ID within this folder should be replaced with the module name in an underscored format such as bat_grenades or enderman_support_class. This should contain only lowercase characters and underscores and should match the module name on the website if the module already exists.
• MODULE_NAME should be replaced with a display name for the module as this is visible to players such as Bat Grenades or Enderman Support Class. This should match the name on the website if the module already exists.

Folders

Within the data folder there are three folders for the different namespaces this module will use. If the module is an extension, you will need an additional module for the base module. Because we merge modules with a copy of the base clock certain folders and files should not be included once the module is submitted but are included in the template so you can test your module.

/minecraft/

This folder simply contains code that lets Minecraft run the Gamemode 4 clocking system. Nothing in this folder needs to be changed.

/gm4/

This folder contains a copy of the Gamemode 4 clocking system and small changes need to be made (see placeholder values above). Be sure not to miss any of these placeholders! Do not change anything else in these files. If the module does not contain advancements then the file under gm4/advancements should be deleted. Otherwise the advancement details should be updated. The root.json file should not be deleted or changed.

/template/

This folder should be renamed to MODULE_ID. All your module code should be within this folder or within sub-folders. Place your main commands in the main.mcfunction file and any commands that should run every tick (avoid this if possible) into pulse_check.mcfunction.

Naming and formatting standards

Please be sure to match the formatting for Gamemode 4 modules to ensure readability and consistency.

• Any name, scoreboard name or tag should be formatted as lowercase_with_underscores
• Scoreboards and tags should begin with the gm4_ prefix.
• fake players used to store numbers for scoreboard operations should be named as a "#" followed by that number e.g. scoreboard players set #100 gm4_some_scoreboard 100
• Entities that aren't visible to the player (markers) should have custom names beginning with gm4_ if this does not interfere with functionality.
• Names for the above two points should be as clear and relevant as possible to avoid confusion or two modules sharing the same name by mistake.
• Lore on items should have the first word capitalized and no fullstop at the end of the sentence if there is only one sentence. Other punctuation (?!) can be added.
• ANY FUNCTION that is run as an entity should have a comment on the first line stating the context of @s so it is clear what runs this file e.g. #@s = cows with speed limit=..1 of red mushrooms
• ALL FUNCTIONS except those included with the template file should list the functions they are called from in a comment on the first or second line of the file e.g. #run from main. More complicated modules with subdirectories should specify the more specific file path e.g. #run from zauber_cauldrons:cauldron/create

Sending us your module code

To send us your finished module for testing and approval, simply submit a pull request and leave a comment if you have additional notes. Make sure to delete files related to the base clocking system. Specifically make sure:

• Delete the load.json and tick.json files from minecraft/tags/functions/
• Delete functions from the gm4 namespace. Advancements and load/tick tags should be left in there though.
• Make sure that #$moduleUpdateList is on the last line containing text of your module's init.mcfunction

Updating a module on the repo

If you've spotted a bug in a module or have a performance improvement you wish to make, create a branch of the repo similar to the process outlined in the section above and make your changes. Once you have edited the module files, create a pull request and leave a detailed note on why you have made your changes.
