App Works in Editor, but blank screen when built

Getting Started

Hi,

Looking for help in the early stages of my Unity development life.

I am unable to get my app running, I just get a blank screen after the loading bar has completed. Tested in WebGL (Chrome and Edge), Android and Standalone PC. I’m hoping I missed something fundamental.

In the Unity IDE, it runs fine. (2019.2.4f1). I am using ShareMyGame.com to test the WebGL, so that I am confident that the platform supports WebGL. Another tutorial game I uploaded works fine.

ShareMyGame.com by GameDev.tv (Available until 26/09/2019)

I call it an app rather than a game, as it is a simple interface with 5 buttons, a text edit box, and a dynamic list of buttons in a scroll rect. Clicking the buttons starts and stops a timer and saves the times to a List<>.

I have checked the console and there are no error messages. I do not know how to trace potential issues any other way.

I added Debug.Log messages to Awake() and Start() attached to the main camera, and these are not output in the console; no code is running.

(This issue started as a post here , when I thought it was only WebGL)

Just to verify you have been adding the scenes to the build settings, right?

Thanks for the reply, I just came to the same conclusion a couple of hours ago, after 3 days of racking my brains. And you are absolutely correct!

The mistake I made was renaming the default scene (there is only one scene) by saving it as a different name. But of course at this stage, the Build Settings have already been set up with the original scene. I even remember thinking it will be fine to not delete the original scene from disk, it’s only a small file.

The final clue that lead me to the answer was when I saw the IDE clear my scene structure as it built (I now know it was loading “SampleScene”). At this point, I changed the background colour of the camera from the default blue to green, and found that when I built the project, the background was still blue…in the words of Obi Wan, this is not the scene you are looking for.

Thanks again for looking at my issue.
