==============================
|
|
|
|
**繼承：** :ref:`RefCounted<class_RefCounted>` **<** :ref:`Object<class_Object>`
|
|
|
|
用於在編輯器資源選擇器的本文功能表中新增從一種資源格式到另一種資源格式的自定義轉換器的外掛程式；例如，將 :ref:`StandardMaterial3D<class_StandardMaterial3D>` 轉換為 :ref:`ShaderMaterial<class_ShaderMaterial>`\ 。

說明

----
|
|
|
|
當編輯器屬性檢視器中的資源被調出本文功能表時，\ **EditorResourceConversionPlugin** 被呼叫。相關的轉換外掛程式將作為功能表選項出現，以將給定的資源轉換為目標型別。
|
|
|
|
下面展示了一個將 :ref:`ImageTexture<class_ImageTexture>` 轉換為 :ref:`PortableCompressedTexture2D<class_PortableCompressedTexture2D>` 的基本插件範例。
|
|
|
|
|
|
.. tabs::
|
|
|
|
.. code-tab:: 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
|
|
|

要使用 **EditorResourceConversionPlugin**\ ，請先使用 :ref:`EditorPlugin.add_resource_conversion_plugin()<class_EditorPlugin_method_add_resource_conversion_plugin>` 方法註冊它。

|
|
|
|
獲取輸入 :ref:`Resource<class_Resource>` 並將其轉換為 :ref:`_converts_to()<class_EditorResourceConversionPlugin_private_method__converts_to>` 中給定的型別。返回的 :ref:`Resource<class_Resource>` 是轉換後的結果，輸入的 :ref:`Resource<class_Resource>` 保持不變。
