RID

A handle for a Resource's unique identifier.

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.

通过 C# 使用该 API 时会有显著不同，详见 :ref:doc_c_sharp_differences\ 。

运算符

构造函数说明

RID RID ( )

Constructs an empty RID with the invalid ID 0.

RID RID ( from: RID )

Constructs a RID as a copy of the given RID.

方法说明

int get_id ( ) const¹

Returns the ID of the referenced low-level resource.

bool is_valid ( ) const¹

Returns true if the RID is not 0.

运算符说明

bool operator != ( right: RID )

Returns true if the RID s are not equal.

bool operator < ( right: RID )

Returns true if the RID's ID is less than right's ID.

bool operator <= ( right: RID )

Returns true if the RID's ID is less than or equal to right's ID.

bool operator == ( right: RID )

Returns true if both RID s are equal, which means they both refer to the same low-level resource.

bool operator > ( right: RID )

Returns true if the RID's ID is greater than right's ID.

bool operator >= ( right: RID )

Returns true if the RID's ID is greater than or equal to right's ID.
