Crust is a code library and testing toolkit designed to make some people's lives easier and provide some very basic gameplay features. Everything is configurable.
The testing toolkit:
The primary feature of this toolkit is a set of customizable and keybindable command-driven buttons added to the inventory screen. There are currently 19 built-in buttons and 16 user-defined buttons (pick its look and slap in whatever commands you want it to run). As an added bonus, the mod allows you to configure the default game rules for newly created worlds.
Crust modes:
Additional player capabilities mainly for testing purposes. The starting modes for new players, required OP level to change each mode, some client preferences, and server limitations are all configurable.
By default, the only mode that is enabled for new players and does not require 'cheating ability' is Magnet.
Available modes:
- Magnet - Pull nearby items toward you.
- Undying - Fully recover instead of dying.
- Unbreaking - Frequently fully repairs your items (note: does NOT prevent them from taking damage).
- Uneating - Restore food level when it drops below a threshold.
- Destroy-on-pickup - Manage inventory clutter. Destroy all items that try to invade your inventory!
- Super vision - Continuous night vision, disables (water) fog and blindness.
- Super speed - Increases sprint speed.
Commands:
Extra inventory buttons and 'Crust mode' management are command-driven. This is how they work!
Available commands:
- /crustclean pointer [<player>] - Destroy item on pointer.
- /crustmode [<player>] - Check active Crust modes.
- /crustmode <mode> (disable|<value>) [<players>] - Enable or disable a Crust mode.
- /crustportal (<portal_type>) [<target>] - Create a dimension portal.
- /crustrecover [all|health|hunger|effects] [<targets>] - Restore health/hunger and/or remove all negative effects.
Config management:
Crust provides its own config implementation as an alternate to Forge's configs.
Key features of Crust configs:
- Easy for modders to implement configs, easy for players to use configs.
- Organize and format your configs the way you want them.
- Editable in-game through GUI (not all field types are supported yet!).
- Useful built-in field types and the ability to implement your own.
Other modding utilities:
- Advancement load event.
- Tile entity bounding box renderer (simple renderers than only run when F3+B is on).
- Portal registry for /crustportal command.
- Data gen tools (currently just a loot table builder).
- Named setBlock flags and entity/level event codes.
- NBT and miscellaneous math helpers.
