Chartboost MainThreadDispatcher Plugin for Unity

A way of dispatching functions to the main thread in Unity projects. Useful for functions that Unity limits to the main thread from different threads.

Installation

This package is meant to be a dependency for other Chartboost Packages;however, if you wish to use it by itself, it can be installed through UPM & NuGet as follows:

"dependencies": {
    "com.chartboost.unity.threading": "1.0.0",
    ...
},
"scopedRegistries": [
{
    "name": "NpmJS",
    "url": "https://registry.npmjs.org",
    "scopes": [
    "com.chartboost"
    ]
}
]

Usage

Simple Actions

Utilize the following methods to execute calls on the main thread:

void TestAction(object state){
    //Execute logic on main thread
    Debug.Log("This is called in the main thread")
}

// Synchronous; blocks until the callback completes
MainThreadDispatcher.Send(TestAction);

// Asynchronous; send and forget
MainThreadDispatcher.Post(TestAction)

Tasks

Taks can be utilized in Unity. However, if they contain code that must run on the Unity main thread, the Task too should also be run in the main thread. Use the following:

MainThreadDispatcher.MainThreadTask(async () =>{
    // Mostly useful when calling task initially from outside of the Unity environment
    await myTask();
});

Task Continuations

Task continuations are useful when trying to call asynchronous code from a synchronous environment. The following examples represent the same logic.

private void MySyncrhonousMethod(){
    MyAsynchornousTask().ContinueWithOnMainThread(taskContinuationResultTask => {
        // perform any continuation logic here.
        Debug.Log("My task finished!")
    });
}

private async void MyAsyncrhonousMethod(){
    var taskResult = awat MyAsynchronousTask();
    Debug.Log("My task finished!")
}
