Singleton used to load resource files.
</brief_description>
<description>
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].

<methods>
<method name="add_resource_format_loader">
<return type="void" />
<param index="0" name="format_loader" type="ResourceFormatLoader" />
<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>
</method>
<method name="exists">
<return type="bool" />
<param index="0" name="path" type="String" />
<param index="1" name="type_hint" type="String" default="""" />
<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].
</description>
</method>
<method name="get_dependencies">
<return type="PackedStringArray" />
<param index="0" name="path" type="String" />
<description>
Returns the dependencies for the resource at the given [param path].
</description>
</method>
<method name="get_recognized_extensions_for_type">
<return type="PackedStringArray" />
<param index="0" name="type" type="String" />
<description>
Returns the list of recognized extensions for a resource type.
</description>
</method>
<method name="get_resource_uid">
<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.
</description>
</method>
<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.
</description>
</method>
<method name="load">
<return type="Resource" />
<param index="0" name="path" type="String" />
<param index="1" name="type_hint" type="String" default="""" />
<param index="2" name="cache_mode" type="int" enum="ResourceLoader.CacheMode" default="1" />
<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.
</description>
</method>
<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.
</description>
</method>
<method name="load_threaded_get_status">
<return type="int" enum="ResourceLoader.ThreadLoadStatus" />
<param index="0" name="path" type="String" />
<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.
</description>
</method>
<method name="load_threaded_request">
<return type="int" enum="Error" />
<param index="0" name="path" type="String" />
<param index="1" name="type_hint" type="String" default="""" />
<param index="2" name="use_sub_threads" type="bool" default="false" />
<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.
</description>
</method>
<method name="remove_resource_format_loader">
<return type="void" />
<param index="0" name="format_loader" type="ResourceFormatLoader" />
<description>
Unregisters the given [ResourceFormatLoader].
</description>
</method>
<method name="set_abort_on_missing_resources">
<return type="void" />
<param index="0" name="abort" type="bool" />
<description>
Changes the behavior on missing sub-resources. The default behavior is to abort loading.
</description>
</method>

<constants>
<constant name="THREAD_LOAD_INVALID_RESOURCE" value="0" enum="ThreadLoadStatus">
The resource is invalid, or has not been loaded with [method load_threaded_request].
</constant>
<constant name="THREAD_LOAD_IN_PROGRESS" value="1" enum="ThreadLoadStatus">
The resource is still being loaded.
</constant>
<constant name="THREAD_LOAD_FAILED" value="2" enum="ThreadLoadStatus">
Some error occurred during loading and it failed.
</constant>
<constant name="THREAD_LOAD_LOADED" value="3" enum="ThreadLoadStatus">
The resource was loaded successfully and can be accessed via [method load_threaded_get].
