RID

Resource 的唯一識別碼的控制碼。

說明

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.

Note: In a boolean context, an RID will evaluate to false if it has the invalid ID 0. Otherwise, an RID will always evaluate to true. This is equivalent to calling is_valid().

備註

使用 C# 操作此 API 時有顯著差異，詳見 C# API 與 GDScript 的不同。

建構子

RID	RID()
RID	RID(from: RID)

方法

int	get_id() const
bool	is_valid() const

運算子

bool	operator !=(right: RID)
bool	operator <(right: RID)
bool	operator <=(right: RID)
bool	operator ==(right: RID)
bool	operator >(right: RID)
bool	operator >=(right: RID)

建構子說明

RID RID() 🔗

建構空的 RID，內容為無效的 ID 0。

---

RID RID(from: RID)

Constructs an RID as a copy of the given RID.

---

方法說明

int get_id() const 🔗

返回引用的底層資源的 ID。

---

bool is_valid() const 🔗

如果該 RID 非 0，則返回 true。

---

運算子說明

bool operator !=(right: RID) 🔗

如果 RID 不相等，則返回 true。

---

bool operator <(right: RID) 🔗

如果該 RID 的 ID 小於右側 right 的 ID，則返回 true。

---

bool operator <=(right: RID) 🔗

如果該 RID 的 ID 小於等於右側 right 的 ID，則返回 true。

---

bool operator ==(right: RID) 🔗

如果 RID 相等，則返回 true，表示它們引用的是同一個底層資源。

---

bool operator >(right: RID) 🔗

如果該 RID 的 ID 大於右側 right 的 ID，則返回 true。

---

bool operator >=(right: RID) 🔗

如果該 RID 的 ID 大於等於右側 right 的 ID，則返回 true。
