Setup Guide Unity Plugin
There are only a few steps necessary to add the Wikitude Unity Plugin to your existing Unity project. This guide will explain them in detail. In general the steps are
- Import the Wikitude.unitypackage into your project
- Add the
WikitudeCameraand one of the
Trackerprefabs to the Unity scene hierarchy and configure their properties
- Add a custom augmentation to the tracker as child GameObject to the
- Export your project in order to fully integrate the Wikitude API in your Unity project
Import the Wikitude.unitypackage
The Wikitude Unity Plugin comes as a standard .unitypackage and can be imported through the usual Unity package import procedure.
In your Unity project, open the
Assets dropdown menu and choose
Import Package -> Custom Package.
Select the downloaded Wikitude.unitypackage in the presented open file browser and click
open. You should import all items that are part of the Wikitude.unitypackage.
Use the Wikitude Unity plugin
After the Wikitude.unitypackage was imported, its components and scripts can be used to define a custom augmented reality experience. The example section describes in more detail how those prefabs and scripts can be used to do so.
Export and Xcode Build Settings Changes
Once the application is setup in Unity and ready for testing on a real device, it needs to be exported as an Xcode project for iOS, Android Studio project for Android, or Visual Studio project for UWP. Alternatively, for Android you can build the .apk directly from Unity.
Export to Xcode
iOS developers need to open the exported project and manually do the steps listed below.
- Before exporting, make sure the
Target minimum iOS versionis set to 9.0 or later and
Camera Usage Descriptionis set to an appropriate message in the Unity in Player Settings. These settings can also be done in the Xcode project, but setting them in Unity will ensure it they don't get overwritten when rebuilding your project.
- After the Xcode project was exported, the
WikitudeSDKframework has to be added as an
After these steps are done once, building with
Append or by pressing
Cmd + B will ensure that the settings are kept.
Export an .apk file
If you don't need an Android Studio project, building directly from Unity is the fastest way to run your app on an Android device.
- In Unity open
File | Build Settings...
- Make sure
Androidis the current build target. If not, select
Androidfrom the list and click
Build And Runand choose where to save the .apk file. If you have an Android device connected, it will also install the app on it.
After this is done once, pressing
Ctrl + B (Windows) or
Cmd + B (Mac) will automatically create the .apk file and install it on your device, if it is connected.
64 bit support for Android
If you are using 2018.1 or later, you can enable experimental support for 64 bit builds on Android from Player Settings. To enable 64 bit support in the Wikitude binaries, copy the .aar files from the
Libraries/Android/ARM64 folder inside the downloaded package into the
Asssets/Plugins/Android folder in the Unity project folder, replacing the existing ones there.
After that, simply build as usual.
Export to Android Studio
Unfortunately Unity projects exported as Android Studio projects do not work out of the box. Some manual work is required which we described in detail below:
- In Unity open
File | Build Settings..., check
Google Android Projectand click
- Open Android Studio and click
Import Project (Eclipse ADT, Gradle, etc.)
- Within the file selection dialog, navigate to the folder where you exported the project and select the folder named after your app
- In the next step choose a new, empty folder to import and click on
- Finish importing by clicking
Finishon the next screen
- In Android Studio open
File | New | New Module ...
Import .JAR/.AAR Packageand click on
File name:navigate to the folder where you originally exported the project from Unity and then to the sub-folder named after your app
- Select the file
wikitude-unity-bridge.aarunder libs and click on
- Open the file
build.gradle (Module: YOUR_APP_NAME)and add the line
compile project(':wikitude-unity-bridge')under dependencies
- The project is now running in Android Studio
Export to Visual Studio
When building for UWP, the following settings need to be enabled to make sure that the SDK is compatible with Unity.
From the Build Settings menu, please make sure that:
Target Deviceis set to
Build Typeis set to
Build and Run onis set to
Additionally, from the Player Settings -> Other Settings:
Graphics APIsis set to
Scripting Backendis set to
And from Player Settings -> Publishing Settings:
At this point, the project can be exported to Visual Studio. Once the project is exported, you can build the project for
Unity Requirements and supported versions
- Unity 5.5.6 or higher
- Rendering engines
- OpenGL ES 2
- OpenGL ES 3.x
- Metal (iOS only)
- Direct3D 11 (UWP only)
- Because 64 bit libraries are not enabled by default on Android, performance on such devices might be lower than similar devices running iOS 64 bit. Please see the Android build section for more information on how to enable 64 bit support on Android.
