ClassLuaItemStackextendsLuaItemCommonchanged

A reference to an item and count owned by some external entity.

In most instances this is a simple reference as in: it points at a specific slot in an inventory and not the item in the slot.

In the instance this references an item on a LuaTransportLine the reference is only guaranteed to stay valid (and refer to the same item) as long as nothing changes the transport line.

Attributes

valid_for_read :: Read boolean  

Is this valid for reading? Differs from the usual valid in that valid will be true even if the item stack is blank but the entity that holds it is still valid.

prototype :: Read LuaItemPrototype  

Prototype of the item held in this stack.

name :: Read string  

Prototype name of the item held in this stack.

type :: Read string  

Type of the item prototype.

count :: Read|Write uint  

Number of items in this stack.

health :: Read|Write float  

How much health the item has, as a number in range [0, 1].

quality :: Read LuaQualityPrototype   new

The quality of this item.

spoil_tick :: Read|Write uint   new

The tick this item spoils, or 0 if it does not spoil. When writing, setting to anything < the current game tick will spoil the item instantly.

spoil_percent :: Read|Write double   new

The percent spoiled this item is if it spoils. 0 in the case of the item not spoiling.

item :: Read LuaItem  ?new

If the item has additional data, returns LuaItem pointing at the extra data, otherwise returns nil.

is_module :: Read boolean  

If this is a module

valid :: Read boolean  

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 :: Read string  

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.
