Windows batch file which invokes appropriate version of Unity.exe without UnityHub.

• Windows 10/11
• pwsh (PowerShell7)
• Unity 2019 or greater.

You can set up your Unity project with the following commands:

pushd "\PATH\TO\Your\UnityProject\"
where.exe ProjectSettings:ProjectVersion.txt && curl.exe -JOL https://raw.githubusercontent.com/t-mat/OpenUnityProject/main/OpenUnityProject.cmd
.\OpenUnityProject.cmd

Please note that \PATH\TO\Your\UnityProject\ means the root directory of your Untiy project. The root directory must contains Assets/ etc.

\PATH\TO\Your\UnityProject\
|
+---Assets
|
+---ProjectSettings
|   |
|   +---ProjectVersion.txt
|
+---OpenUnityProject.cmd      <===

Run the copied version of OpenUnityProject.cmd.

• You can invoke it via Explorer, Command prompt or PowerShell.

It will read ProjectSettings/ProjectVersion.txt, find appropriate version of Unity.exe and invoke it.

• Or it reports an error.
• It tries to avoid to launch UnityHub.

If you put OpenUnityProject.cmd to the %PATH%, you can invoke it as a "normal" command.

cd /d C:\Path\To\Your\UnityProject
OpenUnityProject.cmd

--open-unity-project-with=XXX

• You can specify the desired version of unity.exe.
• For example: OpenUnityProject.cmd --open-unity-project-with=2022.3.19f1

New versioning convention specifies Unity 6 as version 6000. For example, you can invoke Unity 6000.0.0b11 by the following command:

cd /d C:\Path\To\Your\UnityProject
OpenUnityProject.cmd --open-unity-project-with=6000.0.0b11

pushd "%USERPROFILE%\Documents"
git clone https://github.com/t-mat/OpenUnityProject.git
cd OpenUnityProject
