|
Singleton used to load resource files from the filesystem.
|
|
It uses the many [ResourceFormatLoader] classes registered in the engine (either built-in or from a plugin) to load files into memory and convert them to a format that can be used by the engine.
|
|
[b]Note:[/b] You have to import the files into the engine first to load them using [method load]. If you want to load [Image]s at run-time, you may use [method Image.load]. If you want to import audio files, you can use the snippet described in [member AudioStreamMP3.data].

<return type="void" />

|
|
<param index="1" name="at_front" type="bool" default="false" />
|
|
<description>
|
|
Registers a new [ResourceFormatLoader]. The ResourceLoader will use the ResourceFormatLoader as described in [method load].
|
|
This method is performed implicitly for ResourceFormatLoaders written in GDScript (see [ResourceFormatLoader] for more information).

<description>
|
|
Returns whether a recognized resource exists for the given [param path].
|
|
An optional [param type_hint] can be used to further specify the [Resource] type that should be handled by the [ResourceFormatLoader]. Anything that inherits from [Resource] can be used as a type hint, for example [Image].

Returns the dependencies for the resource at the given [param path].

Returns the list of recognized extensions for a resource type.

<return type="int" />

<param index="0" name="path" type="String" />
|

<description>
|
|
Returns the ID associated with a given resource path, or [code]-1[/code] when no such ID exists.

<method name="has_cached">
|
|
<return type="bool" />
|
|
<param index="0" name="path" type="String" />
|
|
<description>
|
|
Returns whether a cached resource is available for the given [param path].
|
|
Once a resource has been loaded by the engine, it is cached in memory for faster access, and future calls to the [method load] method will use the cached version. The cached resource can be overridden by using [method Resource.take_over_path] on a new resource for that same path.

<method name="load">

|
|
<description>
|
|
Loads a resource at the given [param path], caching the result for further access.
|
|
The registered [ResourceFormatLoader]s are queried sequentially to find the first one which can handle the file's extension, and then attempt loading. If loading fails, the remaining ResourceFormatLoaders are also attempted.
|
|
An optional [param type_hint] can be used to further specify the [Resource] type that should be handled by the [ResourceFormatLoader]. Anything that inherits from [Resource] can be used as a type hint, for example [Image].
|
|
The [param cache_mode] property defines whether and how the cache should be used or updated when loading the resource. See [enum CacheMode] for details.
|
|
Returns an empty resource if no [ResourceFormatLoader] could handle the file.
|
|
GDScript has a simplified [method @GDScript.load] built-in method which can be used in most situations, leaving the use of [ResourceLoader] for more advanced scenarios.

<method name="load_threaded_get">
|
|
<return type="Resource" />
|
|
<param index="0" name="path" type="String" />
|
|
<description>
|
|
Returns the resource loaded by [method load_threaded_request].
|
|
If this is called before the loading thread is done (i.e. [method load_threaded_get_status] is not [constant THREAD_LOAD_LOADED]), the calling thread will be blocked until the resource has finished loading.

<param index="1" name="progress" type="Array" default="[]" />
|
|
<description>
|
|
Returns the status of a threaded loading operation started with [method load_threaded_request] for the resource at [param path]. See [enum ThreadLoadStatus] for possible return values.
|
|
An array variable can optionally be passed via [param progress], and will return a one-element array containing the percentage of completion of the threaded loading.

|

<param index="3" name="cache_mode" type="int" enum="ResourceLoader.CacheMode" default="1" />
|
|
<description>
|
|
Loads the resource using threads. If [param use_sub_threads] is [code]true[/code], multiple threads will be used to load the resource, which makes loading faster, but may affect the main thread (and thus cause game slowdowns).
|
|
The [param cache_mode] property defines whether and how the cache should be used or updated when loading the resource. See [enum CacheMode] for details.
