Can coroutines return a value?

Can coroutines return a value?

A Unity Coroutine is a C# generator. Every time you call yield in a generator you are “returning” a value. You do it by running the generator yourself instead of letting Unity do it, and exposing the yielded value using a public property.

What is yield return null?

yield return null will wait until the next frame and then continue execution. In your case it will check the condition of your while loop the next frame. The “why this is necessary” is probably because you want the object to move by an input every frame.

Does yield break stop a coroutine?

Simply adding the yield break statement will end a Coroutine before it’s finished.

How do you return from 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.

How do you break a coroutine in Assassin’s Creed Unity?

After exiting for loop, coroutine will stop. You can also use yield break to stop execution of coroutin, if specific condition is met: IEnumerator MyCoroutine()

What is a yield return?

Yield is the income returned on an investment, such as the interest received from holding a security. The yield is usually expressed as an annual percentage rate based on the investment’s cost, current market value, or face value. Yield is forward-looking.

What is yield return null in C#?

Short answer: yield return null – wait for the next frame and continue execution from this line.

Does yield return continue?

The short answer: If you don’t want to yield return something, don’t yield return anything. There’s yield return to return the next element in the collection and then there’s yield break to end the iteration.

How do you check if a coroutine is running?

Just use a bool like this: bool CR_running;

  1. void InvokeMyCoroutine()
  2. {
  3. StartCoroutine(“Coroutine”);
  4. }
  5. IEnumerator Coroutine()
  6. {
  7. CR_running = true;
  8. //do Stuff.

What does IEnumerator do in Unity?

Conclusion: IEnumerator is a . NET type that is used to fragment large collection or files, or simply to pause an iteration. Coroutine is a Unity type that is used to create parallel actions returning a IEnumerator to do so.

What is return in IEnumerable?

Returns an enumerator that iterates through a collection. An IEnumerator object that can be used to iterate through the collection. The following code example demonstrates the implementation of the IEnumerable interfaces for a custom collection.

What is the use of IEnumerator in a collection?

Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here. Returns an enumerator that iterates through a collection. An IEnumerator object that can be used to iterate through the collection.

What is current current in IEnumerator?

Current { get; } The element in the collection at the current position of the enumerator. The following code example demonstrates the implementation of the IEnumerator interfaces for a custom collection. In this example, Current is not explicitly called, but it is implemented to support the use of foreach ( for each in Visual Basic).

How does the IEnumerator interface track the current position?

The key part of a class implementing the IEnumerator interface is tracking the current position in the collection being iterated over: In this implementation, the Current property returns the default value for the type when the enumerator is positioned before the first item or after the last item.
