动态函数签名生成：TypeVar与Unpack的局限及Pydantic解决方案

from abc import ABC
from dataclasses import dataclass
from pathlib import Path
from typing import Generic, Self, TypedDict, TypeVar, Unpack

D = TypeVar("D", bound="_GameObjectDict")

class _GameObjectDict(TypedDict):
    name: str

class AssetDict(_GameObjectDict):
    path: Path

@dataclass
class _AbstractGameObject(ABC, Generic[D]):
    name: str

    @classmethod
    def load(cls, **kwargs: Unpack[D]) -> Self:  # <- 错误：Unpack item in ** argument must be a TypedDict [misc]
        return cls(**kwargs)

@dataclass
class _GameObject(_AbstractGameObject[D], Generic[D]):
    def to_dict(self):
        return _GameObjectDict(name=self.name)

class Asset(_GameObject[AssetDict]):
    path: Path

from abc import ABC

        # 使用config.model_dump()将Pydantic模型转换为字典，传递给构造函数
        return cls(**config.model_dump())

@dataclass

class Asset(_GameObject[AssetDict]):
    path: Path

# 示例用法
if __name__ == "__main__":
    # 创建Asset的配置字典
    asset_config = AssetDict(name="MyAsset", path=Path("/path/to/asset.png"))

    # 使用load方法加载Asset实例
    asset_instance = Asset.load(asset_config)

    game_object_config = _GameObjectDict(name="BasicObject")
    game_object_instance = _GameObject.load(game_object_config)
    print(f"Loaded GameObject Name: {game_object_instance.name}")
