GD0401: The class must derive from Godot.GodotObject or a derived class

规则 ID	GD0401
类别	用法
修复是中断修复还是非中断修复	Breaking - If changing the inheritance chain Non-breaking - If removing the [GlobalClass] attribute
默认启用	是

原因

A type annotated with the [GlobalClass] attribute does not derive from GodotObject.

规则说明

The [GlobalClass] has no effect for types that don't derive from GodotObject. Every global class must ultimately derive from GodotObject so it can be marshalled.

// 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 { }

如何解决冲突

To fix a violation of this rule, change the type to derive from GodotObject or remove the [GlobalClass] attribute.

何时禁止显示警告

Do not suppress a warning from this rule. Adding the [GlobalClass] to a type that doesn't derive from GodotObject is an easy mistake to make and this warning helps users realize that it may result in unexpected errors.
