What does Unity call something that provides some sort of functionality to a GameObject?
The Unity Editor is a popular and useful authoring platform to create cutting edge augmented reality experiences for both handheld devices and digital eyewear. Visit https://unity.com to download and set up Unity. Add Vuforia Engine to
any project, or add our Core Samples that is available in the Unity Asset Store to get you started. NOTE: If your project targets Android API level 31 or above we recommend updating to Vuforia Engine 10.8 or later. Updating will automatically add the manifest permission to allow data retrieval from sensors on Android devices using the VISLAM. Or, you can
manually add the permission Vuforia Engine is a software development kit (SDK) for creating Augmented Reality apps. With the SDK, you add advanced computer vision functionality to your application, allowing it to recognize images, objects, and spaces with intuitive options to configure your app to interact with the real world. Vuforia Engine supports AR app development for
Android, iOS, Lumin, and UWP devices. See: Vuforia Engine Supported Versions This Getting Started guide will show you: The Vuforia Engine is available as a .unitypackage that can be imported into your Unity project from the menu Assets -> Import Package -> Custom Package.... Importing the package will let a script make the necessary changes in your Unity project to install or upgrade to the latest Vuforia Engine SDK. The package will automatically add the latest Vuforia Engine
version to
your Unity project. For more details, please see Vuforia Engine Package Hosting for Unity. To manually check if new updates are available, go to Help -> Vuforia Engine -> Check for Updates: Vuforia Engine SetupThe Vuforia Engine is visible in the GameObject Menu after it was imported. If this menu is missing, it could mean that the Vuforia Engine was not imported correctly. Each scene that tracks and renders augmented content requires an ARCamera GameObject and support apps for both handheld devices and digital eyewear. Steps:
Tip: You can delete the default Main Camera after adding an ARCamera. The ARCamera contains its own Camera component. The Main Camera is not needed unless you are using it to render a specific camera overlay, e.g., user interface or minimap. Adding Vuforia Engine FeaturesAfter activating Vuforia Engine in Unity, you can add features from the Vuforia Engine menu to your project from the Unity GameObject Menu. Please refer to Features Overview for more information on all of the capabilities offered by the Vuforia Engine. You can also add the Vuforia Core Samples from Unity’s Asset Store. The Core Samples include and demonstrate many of the Vuforia Engine Features. The steps below continue to set up a basic Vuforia AR scene. Steps:
TIP: Always maintain an accurate scale between the Vuforia targets and the physical prints or objects. Using targets that deviate in size from the real-life object might impact the tracking quality. See Virtual Scene Scale in Unity for more information. All Vuforia Targets include the following:
On many Vuforia Targets, you can Add Occlusion Object and Add Target Representation. They are created as a child of the target.
NOTE: Area Targets are created with a pre-computed preview mesh. The settings to add occlusion or colliders are available in the AreaTargetBehaviour component. See Area Targets in Unity for details. Upgrade your Vuforia target previewsFrom Vuforia Engine SDK 10.8 and forward, the Vuforia target preview representations are changed to improve the development workflow. Upgrading your project to the latest SDK, will display a message on your Vuforia Targets asking you to Upgrade This Target or Open Upgrade Dialog. Click the Upgrade This Target to upgrade the target to the new representation setup. See Adding Vuforia Engine Features on how that looks. IMPORTANT: Upgrading alters the Vuforia target by removing the old preview that is a child of the Vuforia target. Pointers and references to the old preview should be updated to use a Target Representation instead. Click the Open Upgrade Dialog to update all former previews in the scene or all former previews in all scenes in the project. Adding Digital AssetsAdd digital content to your target as children of the Target. In this way, augmented content is only showed when that target is tracked.
Print Physical TargetsA Vuforia target is in most cases, a physical print or object. If you have imported the Core Samples, you can find these in /Editor/Vuforia/ForPrint as PDFs. All printable Vuforia targets are also available here: Printable Target pdfs Print without scaling. Which component is always attached to a GameObject and Cannot be removed?A GameObject always has a Transform component attached (to represent position and orientation) and it is not possible to remove this.
Which of the following components is attached to every GameObject?A GameObject is like a container for many different components. By default, all GameObject automatically have a Transform component. This is because the Transform defines where the GameObject is located and how it is rotated and scaled.
How do you define game objects in Unity?In Unity, we can create a GameObject using the Instantiate function, which makes a new copy of an existing object:. public GameObject enemy;. void Start() {. for (int i = 0; i < 6; i++) {. Instantiate(enemy);. What function can be created to create new GameObjects within an active game scene Unity?Constructors. Creates a new game object, named name.
