GD0401：類別必須繼承自 Godot.GodotObject 或其衍生類別

規則 ID	GD0401
分類	用法
修正是否會破壞相容性	破壞性變更 - 若更改繼承鏈 非破壞性變更 - 若移除 [GlobalClass] 屬性
預設啟用	是

原因

被 [GlobalClass] 屬性標註的型別沒有繼承自 GodotObject。

規則說明

對於未繼承自 GodotObject 的型別，[GlobalClass] 屬性無效。每個 全域類別 最終都必須繼承自 GodotObject，才能被正確處理。

// This type is not registered as a global class because it doesn't derive from GodotObject.
[GlobalClass]
class SomeType { }

// This type is a global class because it derives from Godot.Node
// which ultimately derives from GodotObject.
[GlobalClass]
class MyNode : Node { }

// This type is a global class because it derives from Godot.Resource
// which ultimately derives from GodotObject.
[GlobalClass]
class MyResource : Resource { }

修正方式

要修正此規則的違規情形，請將型別改為繼承自 GodotObject，或移除 [GlobalClass] 屬性。

什麼時候應該忽略警告

請勿忽略此規則的警告。將 [GlobalClass] 加到未繼承自 GodotObject 的型別很容易出錯，此警告可協助使用者避免導致不可預期錯誤。
