FUNCTION
factory.get_status()	Get factory status
factory.unload()	Unload resources previously loaded using factory.load
factory.load()	Load resources of a factory prototype.
factory.create()	make a factory create a new game object
factory.set_prototype()	changes the prototype for the factory

CONSTANT
factory.STATUS_UNLOADED	unloaded
factory.STATUS_LOADING	loading
factory.STATUS_LOADED	loaded

Functions

factory.get_status()

factory.get_status([url])

This returns status of the factory. Calling this function when the factory is not marked as dynamic loading always returns factory.STATUS_LOADED.

PARAMETERS

[url] string, hash, url the factory component to get status from

RETURNS

status

constant

status of the factory component

factory.STATUS_UNLOADED
factory.STATUS_LOADING
factory.STATUS_LOADED

This decreases the reference count for each resource loaded with factory.load. If reference is zero, the resource is destroyed. Calling this function when the factory is not marked as dynamic loading does nothing.

PARAMETERS

[url] string, hash, url the factory component to unload

EXAMPLES

How to unload resources of a factory prototype loaded with factory.load

factory.unload("#factory")

factory.load()

factory.load([url],[complete_function])

Resources are referenced by the factory component until the existing (parent) collection is destroyed or factory.unload is called. Calling this function when the factory is not marked as dynamic loading does nothing.

PARAMETERS

`[url]`	`string, hash, url`	the factory component to load
`[complete_function]`	`function(self, url, result))`	function to call when resources are loaded. `self` object The current object. `url` url url of the factory component `result` boolean True if resources were loaded successfully

EXAMPLES

How to load resources of a factory prototype.

factory.load("#factory", function(self, url, result) end)

factory.create()

factory.create(url,[position],[rotation],[properties],[scale])

The URL identifies which factory should create the game object. If the game object is created inside of the frame (e.g. from an update callback), the game object will be created instantly, but none of its component will be updated in the same frame. Properties defined in scripts in the created game object can be overridden through the properties-parameter below. See go.property for more information on script properties. Calling factory.create on a factory that is marked as dynamic without having loaded resources using factory.load will synchronously load and create resources which may affect application performance.

PARAMETERS

`url`	`string, hash, url`	the factory that should create a game object.
`[position]`	`vector3`	the position of the new game object, the position of the game object calling `factory.create()` is used by default, or if the value is `nil`.
`[rotation]`	`quaternion`	the rotation of the new game object, the rotation of the game object calling `factory.create()` is used by default, or if the value is `nil`.
`[properties]`	`table`	the properties defined in a script attached to the new game object.
`[scale]`	`number, vector3`	the scale of the new game object (must be greater than 0), the scale of the game object containing the factory is used by default, or if the value is `nil`

RETURNS

id hash the global id of the spawned game object

EXAMPLES

How to create a new game object:

function init(self)
    -- create a new game object and provide property values
    self.my_created_object = factory.create("#factory", nil, nil, {my_value = 1})
    -- communicate with the object
    msg.post(self.my_created_object, "hello")
end

And then let the new game object have a script attached:

go.property("my_value", 0)

function init(self)
    -- do something with self.my_value which is now one
end

factory.set_prototype()

factory.set_prototype([url],[prototype])

Changes the prototype for the factory.

PARAMETERS

`[url]`	`string, hash, url`	the factory component
`[prototype]`	`string, nil`	the path to the new prototype, or nil

EXAMPLES

How to unload the previous prototypes resources, and then spawn a new game object

factory.unload("#factory") -- unload the previous resources
factory.set_prototype("#factory", "/main/levels/enemyA.goc")
local id = factory.create("#factory", go.get_world_position(), vmath.quat())
