Introduction

With Titanium you most of the time create "business apps" which use normal windows, texts, buttons, images,.... For games (2D or 3D) or apps that rely on graphical effects or use OpenGL you would use engines like Unity3D. While you can create UIs in Unity it is very time consuming if you want to recreate a native look and feel.

In this tutorial we will use the advantages of both engines and combine them together in one app. So you can use Titanium to create a native app with native UI elements and switch to a included Unity3D game with the click of a button.

Tools

• Appcelerator Titanium 8.0.0 with Hyperloop
• Unity3D
• Android Studio

Unity3D

Unity allows us to export an Android gradle project. To do this you need to make the following export adjustments:

• export android
• settings
• scripting backend: il2cpp
• switch on arm64

-> export

Android Studio

Now you import the exported project into Android Studio to create a library instead of an app:

• open android studio

• import project folder as gradle project

• open build gradle

• change to apply plugin: 'com.android.library'

• remove applicationId 'com.unity.game'

• remove bundle {..}

• open manifest

• remove

<intent-filter>
    <action android:name="android.intent.action.MAIN" />
    <category android:name="android.intent.category.LAUNCHER" />
    <category android:name="android.intent.category.LEANBACK_LAUNCHER" />
</intent-filter>

• change theme to "@style/Theme.Titanium"

• make project

• copy unity_project/build/outputs/aar/*.aar to app/platform/android/

Appcelerator Titanium

• add this to tiapp.xml

<android
    xmlns:android="http://schemas.android.com/apk/res/android">
    <manifest>
      <application>
        <activity android:name="com.unity.game.UnityPlayerActivity"/>
      </application>
    </manifest>
</android>

• add this to the controller

//const unity = require("com.unity.game.UnityPlayerActivity");
var intent = Ti.Android.createIntent({
	className: "com.unity.game.UnityPlayerActivity",
});
Ti.Android.currentActivity.startActivity(intent);

• build your Titanium app
• run it
