Frame Update Manager and Multithreaded Job Scheduler For Unity it gives you more control that using Update/LateUpdate as it allows you to add/remove Update callbacks to 6 different queues with a given priority between 0 (max) to 255 (min):

• PreFixedUpdate
• FixedUpdate
• PostFixedUpdate
• AfterFixedUpdate (In order, After FixedUpdate is executed and a physics step performed, this queue is executed)
• PreUpdate
• Update
• PostUpdate
• PreLateUpdate
• LateUpdate
• PostLateUpdate

Add to your script using Ashkatchap.Updater;

1. Paste the contents of https://github.com/forestrf/Scheduler/tree/master/Unity/Assets to your project
2. Inside any script that needs to be updated with this solution add:
   1. A variable UpdateReferenceQ updateRef
   2. A method void MyUpdateFunc() { }
   3. Inside OnEnable: updateRef = UpdaterAPI.AddUpdateCallback(MyUpdateFunc, QueueOrder.Update, 127);
   4. Inside OnDisable: UpdaterAPI.RemoveUpdateCallback(updateRef);
3. You can call UpdaterAPI.QueueCallback(actionCallback, QueueOrder.Update) to queue a callback to be executed on the main thread

1. Create a Updater var updater = new Updater();. You can create as many as you want
2. Follow points 2.3 and 2.4 to add and remove callbacks
3. Call updater.Execute(); inside your Game Update Loop
4. You can call updater.QueueCallback(actionCallback, QueueOrder.Update) to queue a callback to be executed on the main thread

For Non-Unity Users: Call Scheduler.MultithreadingStart(updater); being updater a Updater object that will call Execute(); inside the Game Update Loop.

To Add a new job, call var job = Scheduler.QueueMultithreadJob(a, b, c); being:

• a = callback
• b = number of times that the callback has to be called (the calls will be executed in Any thread, even the main thread)
• c = priority

the variable job contains the methods Destroy (given that it is multithreaded it may still be able to be executed) and WaitForFinish (Only works in the main thread, and blocks the thread until the job finishes executing, contributing to it)

The main thread is the thread where the Updater that uses the Scheduler was created
