ResourcePreloader

|
=================
|
|
|
|
**继承：** :ref:`Node<class_Node>` **<** :ref:`Object<class_Object>`
|
|
|
|
用于预加载场景子资源的节点。
|

|
描述
|
|
----
|
|
|
|
这个节点可以预加载场景中的子资源，这样场景加载完成时，所有的资源就都处于就绪可用状态，可以从预加载器获取。选中该节点后，可以使用 ResourcePreloader 选项卡来添加资源。
|
|
|
|
GDScript 提供了简化的 :ref:`@GDScript.preload<class_@GDScript_method_preload>` 内置方法，可以在大多数场景使用，\ **ResourcePreloader** 则可用于更高阶的场合。
