<brief_description>
|
|
Singleton for managing a cache of resource UIDs within a project.
|
|
</brief_description>
|
|
<description>
|
|
Resources can not only be referenced using their resource paths [code]res://[/code], but alternatively through a unique identifier specified via [code]uid://[/code].
|
|
Using UIDs allows for the engine to keep references between resources intact, even if the files get renamed or moved.
|
|
This singleton is responsible for keeping track of all registered resource UIDs of a project, generating new UIDs and converting between the string and integer representation.

|
|
Adds a new UID value which is mapped to the given resource path.
|
|
Fails with an error if the UID already exists, so be sure to check [method has_id] beforehand, or use [method set_id] instead.

<method name="create_id">
|

<return type="int" />
|
|
<description>
|
|
Generates a random resource UID which is guaranteed to be unique within the list of currently loaded UIDs.
|
|
In order for this UID to be registered, you must call [method add_id] or [method set_id].
