Unity Threading makes simple

Overview:

UnityThread is an utility script that allow you to register tasks to be run on the next Update/LateUpdate/FixedUpdate loop, from any thread.

Getting Started:

1. Install (via Unity Package Manager)

Open your Packages/manifest.json file and add the npm as the registry, with the scope "com.ngtrhieu" as followed:

{
  "dependencies": {
    <...your existing dependencies>
  },
  "scopedRegistries": [
    <...other registries, if any>,
    {
      "name": "npm",
      "url": "https://registry.npmjs.org/",
      "scopes": ["com.ngtrhieu"]
    }
  ]
}

Open Unity, go to Package Manager (Windows/Package Manager)

Inside Package Manager, select Advanced/Show Preview Packages

Find Unity Thread package and click Install.

2. Usage

You will need to call CreateUnityThreadInstance() before accessing any UnityThread API.

using UnityEngine;
UnityThread.CreateUnityThreadInstance();

Schedule your code to be executed on the next Update/FixedUpdate/LateUpdate loop simply by doing:

using UnityEngine;

UnityThread.ExecuteInUpdate(() => {
  // this code will be executed on the next Update.
});

UnityThread.ExecuteInLateUpdate(() => {
  // this code will be executed on the next LateUpdate.
});

UnityThread.ExecuteInFixedUpdate(() => {
  // this code will be executed on the next FixedUpdate.
});

// This coroutine will be executed on the next Update loop.
UnityThread.ExecuteCoroutine(ACoroutine());

Tests

Open Packages/manifest.json and add the following item:

{
  "dependencies": {
    <...your existing dependencies>
  },
  "testables": [
    <...your existing packages, if any>
    "com.ngtrhieu.unitythread"
  ]
}

Open Unity Test Runner (Window/General/Test Runner). UnityThread tests should be shown under PlayMode tests.
