can_insert_at_back()  → boolean

Can an item be inserted at the back of this line?


insert_at(position, items)  → boolean

Insert items at a given position.

Parameters

position :: float

Where on the line to insert the items.

Where on the line to insert the items.

items :: ItemStackIdentification

Items to insert.

Items to insert.

Return values

→ boolean

Were the items inserted successfully?


insert_at_back(items)  → boolean

Insert items at the back of this line.

Parameters

items :: ItemStackIdentification

Return values

→ boolean

Were the items inserted successfully?


get_contents()  → dictionary[string → uint]

Get counts of all items on this line, similar to how LuaInventory::get_contents does.

Return values

→ dictionary[string → uint]

The counts, indexed by item names.


line_equals(other)  → boolean

Returns whether the associated internal transport line of this line is the same as the others associated internal transport line.

Parameters

other :: LuaTransportLine

Note

This can return true even when the LuaTransportLine::owners are different (so this == other is false), because the internal transport lines can span multiple tiles.


help()  → string

Attributes

owner :: LuaEntity Read

The entity this transport line belongs to.


output_lines :: array[LuaTransportLine] Read

The transport lines that this transport line outputs items to or an empty table if none.


input_lines :: array[LuaTransportLine] Read

The transport lines that this transport line is fed by or an empty table if none.


valid :: boolean Read

Is this object valid? This Lua object holds a reference to an object within the game engine. It is possible that the game-engine object is removed whilst a mod still holds the corresponding Lua object. If that happens, the object becomes invalid, i.e. this attribute will be false. Mods are advised to check for object validity if any change to the game state might have occurred between the creation of the Lua object and its access.


object_name :: string Read

The class name of this object. Available even when valid is false. For LuaStruct objects it may also be suffixed with a dotted path to a member of the struct.

Operators

# (length) :: uint

Get the number of items on this transport line.


[] (index) :: LuaItemStack

The indexing operator.
