This guide provides details about how to set up a new Unreal Engine game project for Mobile platforms. While Mobile devices have a wide range of specifications and some may support more robust rendering features, the settings detailed here will work with the broadest range of new projects.
1. Project Setup
Click image for full size.
Open Unreal Editor. When the Unreal Project Browser appears, click Games.
Configure your project as follows:
Project Template: Top Down
Target Platform: Mobile
Quality Preset: Scalable
Project Name: MobileTestGame
You can create a project that uses either Blueprint or C++.
Click Create to create the project and open it in Unreal Editor.
2. Overview of Project Defaults
This section provides details on the project defaults from the previous section and why these are recommended for new Mobile projects.
Project Template: Top Down
While all game templates are equipped for Mobile user interfaces, the point-and-click interface for the top-down game is ideally suited for touchscreen use. You can just as easily use the third-person template.
C++ Project vs. Blueprint-Only
Blueprint-only projects can publish to iOS and Android, but there are many features for configuring these platforms that are only available in C++.
You can build and test iOS projects on an iOS device with Blueprint-only projects, even from a Windows machine. However, iOS applications require Xcode to sign and provision a project for shipping on the App Store, so you will need a Mac with Xcode to ship your game eventually.
Android projects benefit from additional debugging options and tools when using a C++ project.
Target Platform: Mobile
Selecting Mobile as your target hardware will disable several features that are either not supported by Mobile devices at all, not commonly supported, or that are too resource-intensive for the lower-end Mobile devices that Unreal Engine supports.
Engine – Rendering
Bloom is disabled.
Separate Translucency is disabled.
Motion Blur is disabled.
Ambient Occlusion is disabled.
Anti-Aliasing Method is set to None.
Project – Maps and Modes
Use Splitscreen is disabled.
Slate
Explicit Canvas Child ZOrder is enabled.
Quality Preset: Scalable
The Scalable setting provides a minimal rendering feature set that disables several post-processes and favors performance over fidelity.
Engine – Rendering
Motion Blur is disabled.
Auto Exposure is disabled.
Anti-Aliasing Method is set to None.
You can change the target Platform and Quality Preset in Project Settings > Target Hardware. You can also change individual settings as necessary for your project, or you can override them on a per-device basis in your Device Profiles.
3. Setting Up Your Project for Android
For full details on setting up your project for Android, refer to the Android Quickstart Guide. The following is a summary of the required steps:
Install the latest version of Android Studio that is compatible with Unreal Engine. Refer to the Android Development Requirements page for information about the Android Studio, SDK, and NDK versions that are compatible with your current version of Unreal Engine. Refer to the Android SDK and NDK setup guide for information about the specific settings you need in Android Studio.
Run the
SetupAndroid.bat,SetupAndroid.command, orSetupAndroid.shscript located in your engine's Extras > Android folder.Open Project Settings > Android, locate the prompt for configuring your project for the Android platform, then click Configure Now. This will add the
Build/Androidfolder to your project.If you have not accepted the Android SDK license, click Accept SDK License in your Project Settings as well.
If you need to support the Google Play Store, scroll down to the Google Play Services section, locate the prompt for configuring for Google Play, then click Configure Now.
Add an Android Package Name with a reverse-domain style string taking the format
com.(OrganizationName).(ProjectName). For this example project, the package name iscom.YourCompany.MobileTestGame.Set up your Android device in Developer Mode, then connect it to your local area network with wi-fi or connect it to your computer with a USB cable. See Setting Up Your Android Device for Development for more details.
4. Setting Up Your Project for iOS
To build a project for iOS, you need an Apple Developer Account and a MacOS computer with Xcode. For full details on setting up your project for iOS, refer to the iOS Quickstart Guide. The following is a summary of the required steps:
Connect Xcode with your Developer Account in Xcode > Preferences > Accounts.
Connect your iOS device to your Mac with a USB cable, then connect Xcode to your device in Window > Devices and Simulators.
Create an Identifier (App ID) for your app on your Apple Developer page. For the Bundle Identifier, provide a reverse-domain string taking the format
com.(OrganizationName).(ProjectName). For this example project, the package name iscom.YourCompany.MobileTestGame.Register your device on the Apple Developer page.
Set Xcode to automatically manage code signing for your project. Make sure the Bundle Identifier uses the same name you used in your App ID.
Create a Provisioning Profile on the Apple Developer page using your Identifier, the Signing Certificate generated by Xcode, and your registered device. Download it to a convenient location, then click and drag it onto Xcode in your dock.
Open your project in Unreal Editor. In Project Settings > Platforms > iOS, set the Bundle Identifier to the same name you used in your App ID. After the editor discovers your Provisioning Profile and Signing Certificate, check the box for each of them.
5. Testing Your Project On-Device
To test your project on a device, connect it to your computer with a USB cable, then click the Platforms dropdown. Your device should appear in the Quick Launch section. If you click the device's name, Unreal Engine will build your project and deploy it to that device.
6. Final Result
After following the steps in this guide, your Mobile project is now ready to build, deploy, and test on both Android and iOS.
