Previously, EditorResourceConversionPlugin nominally existed in scripting, but there was no way for a user to actually register one. This PR adds methods to EditorPlugin for registering/unregistering EditorResourceConversionPlugins. Additionally, it documents EditorResourceConversionPlugin with descriptions and a basic example.

[EditorResourceConversionPlugin] is invoked when the context menu is brought up for a resource in the editor inspector. Relevant conversion plugins will appear as menu options to convert the given resource to a target type.
|
|
Below shows an example of a basic plugin that will convert an [ImageTexture] to a [PortableCompressedTexture2D].
|
|
[codeblocks]
|
|
[gdscript]
|
|
extends EditorResourceConversionPlugin
|
|
|
|
func _handles(resource : Resource):
|
|
return resource is ImageTexture
|
|
|
|
func _converts_to():
|
|
return "PortableCompressedTexture2D"
|
|
|
|
func _convert(itex : Resource):
|
|
var ptex = PortableCompressedTexture2D.new()
|
|
ptex.create_from_image(itex.get_image(), PortableCompressedTexture2D.COMPRESSION_MODE_LOSSLESS)
|
|
return ptex
|
|
[/gdscript]
|
|
[/codeblocks]
|
|
To use an [EditorResourceConversionPlugin], register it using the [method EditorPlugin.add_resource_conversion_plugin] method first.

Takes an input [Resource] and converts it to the type given in [method _converts_to]. The returned [Resource] is the result of the conversion, and the input [Resource] remains unchanged.
