Lua API: Item

Example

mod:item {
	id = "myitem",    -- mandatory
	name = "My Item", -- mandatory
	tiles = "myitem.png",
}

Attributes

groups

Groups of the item. They can be used in recipes, and can also filter Lua-defined inventory widgets.

Each group must be set to 1 if present. Default value for each group is 0, and it cannot exceeds 65535.

Example:

groups = {
	om_fuel = 200 -- example burn time for a coal item
}

Engine groups always start with om_ prefix. If you create your own groups, please prefix them with something to let people know that the group comes from your mod.

Available engine groups:

• om_fuel: used in default:furnace and MouseWidgetItem, the value represents the burn time

harvest_capability

For a tool, set which blocks are easier to mine.

Note: This attribute would need more doc but it'll probably get removed soon.

id

ID of the item. Mandatory field.

Example:

id = "stick"

IDs are usually of the form mod:item but the mod: prefix is prepended automatically so it's not needed.

mining_speed

For a tool, speed at which it mines the block.

Example:

mining_speed = 1 -- this is the default value

name

Label of the item. Mandatory field.

Example:

name = "Stick"

This label is the name that will appear everywhere in the game.

tiles

Texture of the item.

Example:

tiles = "myblock.png"

The textures will be loaded from mods/<your-mod>/textures/items

Note: Currently, you can only use textures of the exact same size (16x16, 32x32) than the other block/item textures in the game.
