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.

备注

There are notable differences when using this API with C#. See C# API 与 GDScript 的差异 for more information.

---

Constructor Descriptions

RID RID ( )

Constructs an empty RID with the invalid ID 0.

---

RID RID ( RID from )

Constructs a RID as a copy of the given RID.

---

Method Descriptions

int get_id ( ) const

Returns the ID of the referenced low-level resource.

---

bool is_valid ( ) const

Returns true if the RID is not 0.

---

Operator Descriptions

bool operator != ( RID right )

Returns true if the RIDs are not equal.

---

bool operator < ( RID right )

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

---

bool operator <= ( RID right )

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

---

bool operator == ( RID right )

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

---

bool operator > ( RID right )

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

---

bool operator >= ( RID right )

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