AltCore adds a custom player inventory screen, accessory slots, and backpacks whose slots are added to the player inventory. In addition, the mod overhauls many vanilla screens into a unified Universal GUI system with support for style presets, configurable spacing, sizes, positions, and the overall look of the interface.
What the mod already has:
- A custom inventory that fully replaces the default one;
- Full support for all standard Minecraft screens;
- A new player inventory screen;
- An accessory system and additional slots;
- Backpacks that expand the inventory;
- Built-in style presets and the ability to create your own;
- Flexible interface customization, including moving windows within each screen;
- Overhaul of many container and utility screens;
- A simplified
/gm 0,1,2 gamemode command.



AltCore is currently in v0.3 Alpha.

- Fixing effect display on the custom inventory screen;
- Configurable default panel positions on screens;
- Compatibility with JEI, NEI, and others;
- Automatic support for other modded containers;
- Further development of the accessory system;
- Further development of the backpack system with auto-pickup, placement in the world, and upgrades;
- More customization options, including custom textures in any screen, gradients, and animated colors;
