GD0402: The class must not be generic

规则 ID	GD0402
类别	用法
修复是中断修复还是非中断修复	中断
默认启用	是

原因

A generic type is annotated with the [GlobalClass] attribute.

规则说明

The Godot editor assumes every global class is instantiable, but generic types can't be instantiated because the type parameters are unbound.

// This type is a valid global class because it's not generic.
[GlobalClass]
class SomeType : Node { }

// This type is not a valid global class because it's generic.
[GlobalClass]
class SomeGenericType<T> { }

如何解决冲突

To fix a violation of this rule, change the type to remove the generic type parameters 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 generic type is an easy mistake to make and this warning helps users realize that it may result in unexpected errors.
