# unitask

* [开源库UniTask笔记-CSDN博客](https://blog.csdn.net/sinat_34014668/article/details/127602629)
* [UniTask中文使用指南(一) - 知乎](https://zhuanlan.zhihu.com/p/572670728)

**示例**

```
UniTask.Void(Push);

private async UniTaskVoid Push() {  
    await UniTask.SwitchToThreadPool();  

    Process.Start(gitPath, $"-C {projectPath} push")?.WaitForExit();  
  
    Debug.Log("Push success");  
}
```

```
  
UniTask.Void(async () => {  
    GameUtil.OpenUIs<LoadingCanvas>();  
  
    AsyncOperation asyncLoad = SceneManager.LoadSceneAsync("Battle");  
    await UniTask.WaitUntil(() => asyncLoad.isDone);  
    var entryBattle = GameObject.FindFirstObjectByType<EntryBattle>();  
    entryBattle.LevelName = levelName;  
});
```

**await**

* 不能 await 返回 async UniTaskVoid 的方法
* UniTaskVoid 只用于最后一层 Unitask.Void(()=>UniTaskVoid)， 所以用 Lambda 之后 UniTaskVoid 就不会出现了
* 要 await 返回 async UniTask 的方法

**从主线程调用子线程**

// Fire and Forget 不管异步返回值

* Unitask.Void( 返回 UniTaskVoid)
* UniTask.Void(async () => Push().Forget());
* UniTask.Void(async () => await Push());
* UniTask.Void(async () => { ... });
* Push().Forget()
* Unitask.Create( 返回 UniTask).Forget
* Unitask 默认在主线程运行, 要切到子线程
* await UniTask.SwitchToThreadPool();
