Moxvallix's GUI Library | Graphical Interface Tool for Minecraft Datapacks

Simplified GUI Creation for Datapacks

This Datapack greatly streamlines graphical interface development for Minecraft. The system operates on a data-driven principle: interfaces are automatically generated based on templates stored in the game's data storage.

Two Operating Modes

"Enderchest" Mode: The interface displays directly in the player's Ender Chest. Perfect solution for adventure maps - works straightforward and requires no additional blocks.

"Barrel" Mode: GUI renders in a container block at your coordinates. Recommended to use Barrels - they allow detecting if the container is opened, preventing simultaneous interface usage by multiple players.

Getting Started

Choose interface type: "barrel" or "enderchest". Then use <type> in commands, replacing it with your selected type.

Core Functions:

• gui:api/<type>/render - creates interface by page ID
• gui:api/<type>/watch - handles GUI interactions

The watch function should run on loop while the graphical interface is active.

Creating Index

Custom GUIs require configuring an index function - determines which interface template to use based on player's gui.page score value.

Index Example:

execute if score @s gui.page matches 1 run function modrif:gui/main_menu
execute if score @s gui.page matches 2 run function modrif:gui/settings
execute if score @s gui.page matches 3 run function modrif:gui/store

Register your function by adding it to the gui:index tag.

Designing GUI Templates

Menu Template Example:

data modify storage gui:page template set value [\n  {slot:12b, page:2s, item:{id:"minecraft:experimental"}},\n  {slot:14b, page:3s, item:{id:"minecraft:space_item"}}\n]

This template places 2 objects:

• Position 12 - "Test Item" calls the settings page
• Position 14 - "Space Analyzer" switches to catalog display

Advanced Interaction

For creating dynamic menus you can modify slots through gui:render/slot tags (reading slot data) and gui:render/item (modifying items).

Customize click actions via specialized extension points gui:select/slot as per your needs.
