RID

Resource 的唯一标识符的句柄。

描述

The RID Variant type is used to access a low-level resource by its unique ID. RIDs are opaque, which means they do not grant access to the resource by themselves. They are used by the low-level server classes, such as DisplayServer, RenderingServer, TextServer, etc.

A low-level resource may correspond to a high-level Resource, such as Texture or Mesh.

Note: RIDs are only useful during the current session. It won't correspond to a similar resource if sent over a network, or loaded from a file at a later time.

备注

通过 C# 使用该 API 时会有显著不同，详见 C# API 与 GDScript 的差异。
