Is there a possibility to use Unity Engine without Unity Editor

Hi Guys!

I wanted to ask if it's possible to use the Unity render without the Unity Editor? Than I have always problems to compile code which is not compatible with the .Net version which Unity uses to compile the project.

Thank you in advance.

Best regards

    I know there are a lot of instances where you'd want your code to run only when actually running on the device, but you want to maintain debug-ability in the Unity Editor. For that, you can use conditional compilation statements #if in your code to make it run in Unity Editor as well -

       //code will not run when app is in the Editor context

    Hope this helps

    @sens are you asking if you could use, for example, a JavaScript Unity project on HoloLens or are you asking if you can reuse a project you've targeted for another platform?

    @AlexD is correct about using conditional compile statements to exclude code from other platforms. He used The #if !UNITY_EDITOR up above but there are many more. For example, if you want to exclude code from an IOS build you could use #if UNITY_IOS. When I am writing code that only works on HoloLens (or Windows 10) I use #if WINDOWS_UWP.

    A mostly complete list of Unity conditional compile statements can be found here.

    If you're asking about running a Unity JavaScript app on HoloLens, I believe that's possible but I've not tested it. You would still need to use the right version of Unity for HoloLens to set the project up and export it, but the JavaScript behaviours should get exported in the Unity asset blob that gets loaded in the UWP app, so I believe at least in theory it would work. If you test this, please let us know the results.
