Error with Mario StarCatcher

[nagayev]

Hello. I ran Mario Starcatcher 2 from this site and saw this: Ruffle version: nightly 2020-11-29

[nagayev]

Sorry, I coudn't just copy paste Error stack: Ruffle doesn't support it.

Your Nightly is out of date. You should just see a black screen on current Nightly. (Also you should be able to highlight the text in the error message and Ctrl C)

The error it currently throws is related to AVM2

AVM2 error: Property does not exist: Some(AvmString { source: Owned("stage") })

@parkerlreed Okey, thanks.

[parkerlreed]

Interestingly it works on current master on desktop

Might just need to wait for the next nightly update (Unless the website is maybe trying to play an advertisement?)

[parkerlreed]

Seems like it's the website trying to do something out of the ordinary. You can play it in the demo with this swf

@parkerlreed Oh, it's interesting. Okay. So should I close this issue?

[parkerlreed]

Might be good to leave it up for a little bit so the loading error on that site can be diagnosed.

The website is no longer online (likely for geopolitical reasons...) but it is archived here: https://web.archive.org/web/20210327051259/http://www.igames.com.ua/FlashGame.aspx?name=mario_starcatcher_2 We can see that the website uses a loader (ima3_preloader_1.5.swf) that loads the actual game. This loader SWF uses ActionScript 3. Here is the error log from running the loader:

AVM2 error: VerifyError: Trait loadBytes in class SafeLoader marked as override, does not override any other trait

Error occured when running AVM2 frame script: VerifyError: Trait loadBytes in class SafeLoader marked as override, does not override any other trait 

loadBytes is being worked on as part of #7858, so this might start working soon!

The IMA3 preloader still doesn't work, but the original game (accessible at http://web.archive.org/web/20210327201418/http://www.igames.com.ua/swf/mario_starcatcher_2.swf) is playable!

Yes. That means nothing has changed. So the issue should not be closed.
