[Problem/Bug]: My Construct 3 game does not work on Xbox.

[Pedro1234-code]

What happened?

Since WebView2 released on Xbox I tried to port my game made using Construct 3 for it. It always worked fine on PC, and still does, but never worked on Xbox. It launches but the launch screen is empty. The only thing that appears is the "Play" button and the background music that plays normally. Once the Construct 3 beta r378 was released (this version officially adds support for Xbox/UWP WebView2 export) I tried to export by the official methods but I still got the same results.

Note that I also tried to launch the game in the Edge browser on Xbox through itch.io and the same thing happened.

@AshleyScirra would this issue be more relevant to Construct 3?

This was also reported to us directly here: Scirra/Construct-bugs#7823

Here is a Visual Studio solution that can be tested: Viajante Espacial.zip

I cannot reproduce this on my Xbox One in developer mode: the game displays identically for me both when run on Windows, and when using the "Remote machine" option to launch directly on the Xbox. However I was testing on an Xbox One, and on the issue filed with us they noted they were using Xbox Series S.

The described result would appear to suggest that the WebGL-rendered canvas element remains black, while other HTML elements (e.g. the button) and audio playback continue to work normally. This could potentially be a bug in the WebGL implementation in WebView2 on the Xbox Series S specifically. The affected user also notes that it works OK on Windows, and only exhibits a problem on Xbox Series S, which is usually good evidence of a problem with WebView2 on Xbox rather than any problem with Construct itself. In fact based on the comment that it reproduces with the Edge browser on Xbox when published to the web, this suggests a problem with the Edge/Chromium browser WebGL implementation on Xbox rather than something specific to WebView2 only. (Is there somewhere else such issues should be reported?)

I don't currently have an Xbox Series S, and would rather not order one in given the likelihood that this is a problem with Edge/WebView2 and not Construct, so I would recommend Microsoft try reproducing this by running the Visual Studio solution I provided on an Xbox Series S.

Note that the same thing happens in Edge browser on Xbox.

Thanks for looking into it @AshleyScirra. @jennifer-jacobs could you help see if the issue reproduces, specifically on the Series S? Seems like it does not repro on Xbox One. Do let me know if someone else is better suited for looking into it.

Just to add that the full game is now released on Microsoft Store for Xbox. I decided to release so more people could test without Dev Mode. The name is "Viajante do Espaço".

Here is the link if anyone would like to test on the full sized version (not the stripped down):

Heard from another person with Series S that same thing is happening to her. I also want to add that I'm not able to play preview on Construct 3 on Xbox Edge. The entire screen goes black for a second and then the tab is closed.

Hi @Pedro1234-code,
Which API specifically doesn't work on Series S? Can you point me to the code in your sample app that has the difference in behavior?

Also, I'm curious if this repros on a Series X (if you have one)?

No I don't have an Xbox Series X, only the S sadly. I can't exactly point which API does not work, but I released the game on Microsoft Store to make it easier for testing (and heard from another Series S user that the same thing happened to her). If you want to test the game you can just download it, it's called "Viajante do Espaço" in portuguese. I can also send you the full project file but I don't think it's needed as there is already a stripped down version of it here. I also wanted you to understand that I don't have so much experience with coding and me and my team decided to use Construct specifically because it's more graphical and beginner friendly.

Also wanted to add that I'm 99% sure that it has some relation with the other bug where you can't play Construct 3 games on Edge. I think it's not related to WebView2 but more with the rendering engine.

@jennifer-jacobs I can confirm that the issue reproduces on Series X. Got the confirmation from someone at Reddit that the same thing occurs on Series X.

[jennifer-jacobs]

I was also able to confirm this problem repros on a Series X. It's been added to our backlog!

@jennifer-jacobs Ok, thanks. Hope it gets solved soon.
