i4 is an inventory system for Minetest with a focus on cohesion. It is a fork of i3, the “next-generation inventory.” Primary differences to i3 include an extended API, more efficient use of screen-space, and general house-keeping.

This mod requires Minetest 5.6+, as it uses newer additions to the formspec API.

Officially-supported mods

These mods have menus built-into i4:

• 3d_armor
• skinsdb
• awards

Configuration

There is currently two minetest.conf settings used by i4:

• i4_progressive_mode = false — A discovery-based system, where the crafting guide only displays recipes whose components you have held before.
• i4_inventory_size = 32 — Players’ inventory-size. Defaults to 32 (or 36, if i3 was previously in use). Only accepted values are 32 and 36.

Notes

i4 uses a larger inventory than the usual inventories in Minetest games. Thus, most chests will be unadapted to this inventory size. The i4 inventory is 9 slots wide by default, such as Minecraft.

Please report bugs on the bug tracker — I don’t bite!

Recommendations

To use this mod in the best conditions:

• Use LuaJIT
• Use the default Freetype font style

Troubleshooting

If the inventory’s font size is too big on certain setups (namely Windows 10/11 or 144 DPI display), you should lower the value of the setting display_density_factor in your minetest.conf. Note that the change is applied after restart.

You can also use the font size slider in the inventory, settings window.
