![]() ![]() This risk of upgrading is entirely on you and must be considered whenever you contemplate a Unity version upgrade.ĭo not upgrade "just for fun" or you may become very unhappy. (Android, Unity 2021.1.3f1) Discussion in Visual Scripting started by Swarog, Jun 16, 2021. Obviously the less you test after the upgrade the more chance you will have of an undiscovered critical issue. Welcome to the Unity Forums Please take the time to read our Code of Conduct to familiarize yourself with the forum rules and how to post constructively. If there are issues in your testing after upgrading Unity, ABANDON the upgrade, revert your project in source control and be back where you were pre-upgrade with the earlier version of Unity. Since you didn't write the third party library, it is up to you to vet it against the new version to make sure it still works. Immediately after any attempted upgrade you should try to view as much of your project as possible, with a mind to looking for broken animations or materials or any other scripting errors or runtime issues.Īfter an upgrade you should ALWAYS build to all targets you contemplate supporting: iOS and Android can be particularly finicky, and of course any third party libraries you use must also "play nice" with the new version of Unity. Once you have source-controlled your project then you may attempt a Unity upgrade. This goes double or triple for non-LTS (Tech Stream) versions of Unit圓D, which can be extremely unstable compared with LTS. If you want to upgrade to a newer version of Unity, do not even consider it until you have placed your project fully under proper source control. Doing so exposes your project to internal inconsistencies and breakage that may actually be impossible to repair. ![]() Any project that has been updated should NEVER be reverted to an earlier version of Unity because this is expressly not supported by Unity. Upgrading to a later version of Unity is a one-way process. ISSUES RELATED TO UPGRADING PROJECTS (eg, changing to a higher Unity version) Here was how I brought up Unity2020.3.41 and the Android SDK 31 on October 30, 2022:Īndroid Gradle errors and other related stuff: Recently (circa July 2022) there have been reports of Unity's installer failing to install the Android Tools. It may also be helpful to work through a tutorial or two for whatever subsystem is making the build fail. Once you identify the subsystem, go to the documentation for it and make sure you are doing it correctly. Most often things that prevent building are third-party libraries such as Firebase. Once you can build a blank project, now bisect the problem by bringing over parts of your current project and building it one subsystem at a time, perhaps stubbing things out that might trigger compiler errors. Until you can build a blank project to the target platform, don't fiddle with anything else. It is generally best to stay with LTS versions of Unit圓D. It may even be necessary to change to a different version of Unit圓D. If the blank project does NOT build, go fix your Unity installation or your other tools, such as Android SDK, NDK, JDK, etc. First, make a blank project with a single blank scene and prove that it builds successfully. ![]()
