Can a coroutine return a value?
A Unity Coroutine is a C# generator. Every time you call yield in a generator you are “returning” a value. That’s what they are intended to do, generate values. The problem isn’t about returning values from a Coroutine, because you’re doing that.
What does a coroutine return?
A coroutine is a special method that allows us to pause and resume the execution of code. When we call a function, the function executes all code inside it and then the function returns. Once the function returns the program continues executing the rest of the code that comes after the function.
How do you return a coroutine in Assassin’s Creed Unity?
To stop a coroutine from “inside” the coroutine, you cannot simply “return” as you would to leave early from an ordinary function. Instead, you use yield break . You can also force all coroutines launched by the script to halt before finishing.
Does yield break return null?
6 Answers. To give a code example, say you want to write an iterator that returns nothing if the source is null or empty. Without the yield break it becomes impossible to return an empty set inside an iterator. yield break specifies that the method should stop returning results.
What does yield return mean unity?
The yield return statement is special; it is what actually tells Unity to pause the script and continue on the next frame.
What does yield break return?
It specifies that an iterator has come to an end. You can think of yield break as a return statement which does not return a value. For example, if you define a function as an iterator, the body of the function may look like this: for (int i = 0; i < 5; i++) { yield return i; } Console.
How to get the return value of a coroutine?
If you want registerUser to run as a coroutine, you need to call StartCoroutine (), not simply call registerUser (). If a function contains “yield return” and you run it normally, it returns a lazily-evaluated collection. If you want it to run as a regular synchronous function, get rid of “yield return”.

What is the coroutine in monobehaviour.startcoroutine?
MonoBehaviour.StartCoroutine returns a Coroutine. Instances of this class are only used to reference these coroutines, and do not hold any exposed properties or functions. A coroutine is a function that can suspend its execution (yield) until the given YieldInstruction finishes. using UnityEngine; using System.Collections;
Which is an example of a coroutine in Java?
Instances of this class are only used to reference these coroutines, and do not hold any exposed properties or functions. A coroutine is a function that can suspend its execution (yield) until the given YieldInstruction finishes. // In this example we show how to invoke a coroutine and execute // the function in parallel.
What do you need to know about coroutines?
When the compiler encounters a function which contains a co_await or co_return, it realizes that it’s dealing with a coroutine. It collects the following: The return type of the function. The type of *this, if it’s defined as an instance member function. The types of the parameters, if any.
