“Animations”, “Models”, “Textures”, “Scripts”, etc. One recommended way of setting up an Assets folder is to create individual folders for each type of resource, e.g. It makes sense to keep the Assets folder organized so that all developers know where resources are stored. can be placed.Įverything in this Assets folder and its subfolders is automatically imported into the project and can be integrated into the application. Here, all resources for the project, e.g. Once a new Unity project has been created, the project’s folder contains a subfolder called “Assets”. Once it is installed, it can be integrated with Git and tries to perform an automatic merge of the two versions of the scene. It can become difficult to merge the save files since its contents are mapped to IDs with associated settings.įor this case, Unity provides a tool called Smart Merge. caches, build objects and meta files.Ī problem which can occur in collaborative work is the merging of scenes.Īn entire scene in Unity is stored in one YAML file which means that a conflict arises if multiple team members worked on the same scene. It contains a description of all redundant files which Unity can regenerate, e.g. When setting up a project, a gitignore file should be added at the root level of the Git project.Ī completely set up template for the gitignore file can be found on GitHub. There are multiple alternatives available and one commonly used version control software is Git. When working in a team or alone, it is generally recommended to use a version control software to create backups of the work. 2019.2.2.10 are regarded as different versions. The used version must match exactly, including the minor release number, e.g. When working in a team, all team members must agree on one Unity version. Thus, any Unity updates should be well-planned. Once a project has been upgraded to a newer version, it is not possible to open it with older versions again due to changed APIs and data structures. It can take a while to process the changes and additionally, content may be change automatically, e.g. Opening a Unity project with a newer editor version causes a re-import of all project assets. Unity projects keep track of the editor version which most recently edited the project. Updates to the long term support version focus on stability and are released regularly. 2019.2.10.įor each year, Unity provides a long term support (LTS) version which is recommended for longer lasting projects. Unity’s versions are labelled by a year, a major version number and a minor version number which are separated by dots, e.g. Similarly, the installation can be expanded by additional build support components at any time. It offers a list of all Unity versions and they can be installed or removed at the press of a button. It is a launcher which administers the versions of Unity. the default install location, will overwrite the previously installed version.Ī more comfortable way of handling multiple versions and the build support components is the Unity Hub. Installing multiple versions to the same folder, e.g. If multiple Unity versions are used in parallel, the install location needs to be adapted manually. It is also possible to add platform build support components at a later stage but then installers for each of the platforms need to be downloaded and executed separately. In the installation process, components for different target platforms such as Windows UWP, Linux, Android or iOS can be added.Īll intended target platforms for applications should be selected now. The installer for a Unity version can be downloaded directly from its archive. One can use an installer for a specific Unity version or the intermediate launcher Unity Hub. Many of the presented AR SDKs can be added to Unity projects so that their functionality is available directly in the 3D engine. The required licence level depends on the annual revenue. Unity is available in different pricing levels ranging from a free personal edition to a Pro version with additional support for larger companies. This means that Unity’s graphics can be adapted to different graphic qualities, performances and visual styles.Īpplications can be deployed on more than 25 platforms, including Android, iOS, Windows Standalone and Universal Windows Platform. Unity is a real-time graphics engine by Unity Technologies which developers can utilize to create 2D and 3D applications (Unity, 2020). Instead, 3D engines like Unity (Unity, 2020) or the Unreal Engine (Epic Games, 2020) already offer this functionality as a foundation for the development of real-time graphics applications. Developers of AR applications do not have to start from scratch and (re-)implement the complete graphics pipeline and physics simulations.
