首先,它无法返回值,或者说需要通过一些比较复杂的方法才能使它能够返回值,这样我们不得不写一个很长的单体式协程(monolithic coroutine,大概是这么翻译的吧,我也不清楚);其次,yield无法放入try catch中,我们不得不创建一个混合了同步(try catch)与异步(www.isHttpError或www.isNetworkError)的错误处理机制。 所以,...
答:参考 仅能从主线程中访问 Unity3D 的组件,对象和 Unity3D 系统调用 支持:如果同时你要处理很多事情或者与 Unity 的对象互动小可以用 thread,否则 使用 coroutine。 注意:C#中有 lock 这个关键字,以确保只有一个线程可以在特定时间内访问特定的 对象 14.Unity3D 的协程和 C#线程之间的区别是什么? 答: 多...
Explain what a coroutine is and how they work. Determine when it is appropriate to use coroutines. Implement coroutines with the correct syntax. 2.Before you begin 0 This tutorial is part ofIntermediate Scripting, a collection of basic introductions to a wide range of different programming conce...
What is the equivalent of yield return null; in Coroutine (that run each frame at Update) in an async method ? The nearest I got to find is await Task.Delay(1);, but it DO NOT run every frame. private IEnumerator RunEachFrame() { while (true) { print("Run Each frame righ...
When the coroutine is activated it will execute right up to the next yield statement and then it will pause until it is resumed. You can see where it will resume in the diagram above, based on what you yield. 当协程被激活,它会一直到下一个 yield语句执行,然后它会暂停,直到它恢复。你可以...
TheIEnumeratoris registered as a running Coroutine on this component It also immediately executes everything until the firstyieldstatement Then it depends on what exactly isyielded yield return null;basically means yield once, then continue with the rest of code in the next frame right after the ...

Let us consider the line of code shown below to understand what coroutines is all about.IEnumerator MyCoroutineMethod() { // Your code here… yield return null; } Generally, if you call a function in Unity (or C#, really), the function will run from start to finish. This is what ...
A discussion about custom instructions in coroutines can be found on theUnity Blog. What Coroutines are NOT for For all the benefits of coroutines, there are scenarios which are not suited to them. The most important distinction to draw is that they are NOT the same as threads. By impleme...
IEnumerator MyCoroutineMethod() { // Your code here... yield return null; } Example:IEnumerator MyCoroutine() { Debug.Log("Hello world"); yield return null; //yield must be used before any return } Here, the yield is a special return statement. It is what tells Unity to...
