CoroutineEx

This library aims to provide a more convenient and feature rich abstraction for coroutine-based asynchronous operations in Unity 3D and also attempts to replicate the TAP design pattern and Task class from .NET.

Features

• Allows for precise control over the execution sequence.
• Offers multiple task states.
• Provides a way to return a value from the task.
• Works in Editor scripts.
• Replicates some features from the TAP.

Installation

Follow the guide by this link to install the package using OpenUPM (recommended).

Or you can add the package to your project via UPM using this Git URL: https://github.com/s-rayleigh/CoroutineEx.git

System.Threading.Task vs CoroutineTask

Task	CoroutineTask
Task.Run	CoroutineTask.Run
Task.Delay	CoroutineTask.Delay
Task.CompletedTask	CoroutineTask.CompletedTask
Task.FromCancelled	CoroutineTask.FromCancelled
Task.FromCancelled<>	CoroutineTask.FromCancelled<>
Task.FromException	CoroutineTask.FromException
Task.FromException<>	CoroutineTask.FromException<>
Task.FromResult	CoroutineTask.FromResult
Task.Exception	CoroutineTask.Exception
Task.Status	CoroutineTask.State
Task.WhenAll	CoroutineTask.WhenAll
Task.WhenAny	CoroutineTask.WhenAny
await	yield return
lock or AsyncLock	CoroutineLock
TaskCompletionSource	CoroutineTaskCompletionSource
TaskCompletionSource<>	CoroutineTaskCompletionSource<>

Examples

Wait 5 seconds and print "Hello world!":

CoroutineTask.Run(ctl => 
{
    return Internal();

    IEnumerator Internal()
    {
        yield return CoroutineTask.Delay(TimeSpan.FromSeconds(5));
        Debug.Log("Hello world!");
        ctl.Finish();
        yield return null;
        Debug.Log("This message will never be printed.");
    }
});

Return result from the CoroutineTask:

var task = CoroutineTask<int>.Run(ctl =>
{
    return Internal();

    IEnumerator Internal()
    {
        yield return null;
        ctl.SetResult(42);
    }
});

yield return task;
Debug.Log(task.Result);
