信号
extension_loaded ( extension: GDExtension )
Emitted after the editor has finished loading a new extension.
Note: This signal is only emitted in editor builds.
extension_unloading ( extension: GDExtension )
Emitted before the editor starts unloading an extension.
Note: This signal is only emitted in editor builds.
extensions_reloaded ( )
Emitted after the editor has finished reloading one or more extensions.
枚举
enum LoadStatus:
LoadStatus LOAD_STATUS_OK = 0
The extension has loaded successfully.
LoadStatus LOAD_STATUS_FAILED = 1
The extension has failed to load, possibly because it does not exist or has missing dependencies.
LoadStatus LOAD_STATUS_ALREADY_LOADED = 2
The extension has already been loaded.
LoadStatus LOAD_STATUS_NOT_LOADED = 3
The extension has not been loaded.
LoadStatus LOAD_STATUS_NEEDS_RESTART = 4
The extension requires the application to restart to fully load.
方法说明
GDExtension get_extension ( path: String )
Returns the GDExtension at the given file path, or null if it has not been loaded or does not exist.
PackedStringArray get_loaded_extensions ( ) const1
Returns the file paths of all currently loaded extensions.
bool is_extension_loaded ( path: String ) const1
Returns true if the extension at the given file path has already been loaded successfully. See also get_loaded_extensions.
LoadStatus load_extension ( path: String )
Loads an extension by absolute file path. The path needs to point to a valid GDExtension. Returns LOAD_STATUS_OK if successful.
LoadStatus reload_extension ( path: String )
Reloads the extension at the given file path. The path needs to point to a valid GDExtension, otherwise this method may return either LOAD_STATUS_NOT_LOADED or LOAD_STATUS_FAILED.
Note: You can only reload extensions in the editor. In release builds, this method always fails and returns LOAD_STATUS_FAILED.
LoadStatus unload_extension ( path: String )
Unloads an extension by file path. The path needs to point to an already loaded GDExtension, otherwise this method returns LOAD_STATUS_NOT_LOADED.
