Tetra revolves around modular items and attemps to blend it together with other concepts such as adventure and technology.

Note: Tetra for 1.14+ uses the mGui library, if you're not using the curse client you'll have to install that manually.

Getting Started

1. Craft a mallet using two sticks and two planks
2. Craft and place a vanilla crafting table
3. Right click the table with the mallet to upgrade it into a workbench
4. Craft a vanilla weapon, tool shield or a bow and place it in the workbench
Check the advancements window to learn how to progress further

Modular Items

Tetra allows you to replace parts of items with different parts of different types and materials, some parts can also be improved. Which parts you may use is limited by the items capacity, called integrity. Some parts increase an items integrity while some parts has an integrity cost. Some parts require tools of differing quality to craft.

Currently the following modular items are available:

swords
toolbelts
double headed implements (axes, pickaxes, hammers etc)
single headed implements (shovels, tridents, spears etc)
bows
shields
crossbows (WIP)

Configuration

Mod compatibility

Tetra supports usage of a few materials added by other mods, since tetra uses item tags (or the ore dictionary before 1.14) it's difficult to say exactly which mods are supported. Enchantments from several mods are also supported from 1.14 and forward.
The following non-vanilla materials are supported in 1.16:

bone
* dragon_bone
* wither_bone

fibre
* hemp
* mana_string

gem
* agate
* amethyst
* certus_quartz
* citrine
* ruby
* sapphire
* serendibite

metal
* bronze
* copper
* electrum
* elementium
* infused_iron
* lead
* manasteel
* nickel
* osmium
* silver
* sky
* steel
* terrasteel
* tin

wood
* ancient_wood
* baobab
* cherry
* dreamwood
* livingwood
* maple
* treated_wood

Any mod that adds one of those and tags them correctly would make them available for use in tetra. In 1.12 tetra also supports some materials from thaumcraft and twilight forest.
