About problems with HTML5 builds

marco.giorgini · June 19, 2019, 6:00am

I’m doing a game for a jam (closing in few days) - I can use the game running from defold, even built as win64 exe - but something’s wrong with html5 build (your remote building system - on game page - says there’s an undefined problem - and if I upload the zip online - or if I try to use that version online on another site) I see your logo then the game “stops” (black screen and nothing more)
How can I understand what’s wrong in my game?
Times ago a similar problem was due to duplicated name in resources - but that I could get as an error message with local build - while now I get none.
I mean I don’t want you to found and fix problems for me - but, well, if you’re own building system is able to detect a “problem” I would like to have an hint about it - if possible
Thanks in advance

Open Chrome developer tools and look in the console (Ctrl-Shift-J). Can you copy paste the error messages here?

This is what I see on my website - after uploading

This is instead the messages list I see for the same game on you dashboard page (I build from defold and uploaded)

Thanks for your support

A note - I still don’t have audio resources in game - I write it because there’s a reference to sound in the first log
A second note - a previous build (4/5 days ago) worked

There’s a texture size limit - different from desktop? I may have one 2048x1024 texture (and some others smaller - less than 10/15 at most anyway)

Are you sure you’re on the latest Chrome? Update it. And update your GPU drivers too, just in case they don’t play nice with your version of Chrome. From the errors, it looks like your version might not be supporting WebGL 2.

Though this is weird.

marco.giorgini · June 19, 2019, 6:49am

Thanks - but I’ve tried with other browsers too - FireFox, Edge and Brave - on two different machines

I’ve the game playable from here http://marcogiorgini.com/public/StoryMode/ - could you try it - just to be sure it’s not my computers fault?

marco.giorgini · June 19, 2019, 6:52am

I doesn’t work even of my mobile phone (safari)

AGulev · June 19, 2019, 7:10am

It seems like a problem somewhere in logic. Because I have the same log messages in html5 build as you have but my game works.
What libraries are you using in the game? Do you have some native code?

marco.giorgini · June 19, 2019, 7:07am

only defos

marco.giorgini · June 19, 2019, 7:11am

a question - run html5 version in defold - and build html5 package do the same work? if so that way I could try removing thing and try until I found the issue (as long as you say that errors logged are not a real problems)

Mathias_Westerdahl · June 19, 2019, 8:29am

If you choose “Build HTML5” from the menu, it will build a custom engine for you (if you have native extensions or an app manifest).

sven · June 19, 2019, 8:39am

Could you please try uploading a debug version of the HTML5 game, perhaps there are some log errors that isn’t visible in the release version.

marco.giorgini · June 19, 2019, 8:44am

ok. I can do that but just tonight, when I’m back home. Thanks

marco.giorgini · June 19, 2019, 8:04pm

Ok - I think I got it. At start I check if the engine is in debug (sys.get_engine_info().is_debug to choose which internal config I want to use) - that line it seems to crash - in html5 (not in win, not inside defold)
now I check if I got sys.get_engine_info() before addressing is_debug - and this way it works
Has this any sense?
Anyway now it works even your remote build (!( - not sure how can it be aware of the issue and stopping compilation (while it works in defold) but at the moment evetything works again

Thanks for your support

britzl · June 19, 2019, 9:09pm

So you’re saying that sys.get_engine_info() returned nil?

marco.giorgini · June 19, 2019, 10:06pm

that is what I suspect (in html5) because with this change

local config
local info=sys.get_engine_info()

if info and info.is_debug then
	config=M.game["debugconfig"]
else
	config=M.game["config"]		
end

before was if sys.get_engine_info().is_debug then

the html5 started to work

tomorrow I’m going to verify that better

if you don’t think that’s possible I’ll check it further - I need the html5 working and jam deadline for me is friday night

marco.giorgini · June 19, 2019, 11:47pm

Update: I’ve still have (again) problem - but just on the community page - the following lines are log info there.
I’ve been able to play with html5 version on my site (same browser, same internet line - just different site) - so I keep my finger crossed - maybe this issue is not a real problem

britzl · June 20, 2019, 3:32am

I’m sorry to hear that you’re having problems with html5 builds. Let me know if you’re able to confirm a problem that is reproducible somehow. I’ll happily also take a look at your project should you wish to share it.

marco.giorgini · June 20, 2019, 4:44pm

thanks - really appreciated. Anyway I’ve done some test and on my site and (more important) on gamejolt the html5 version seems to work now (if I check to not use https ) - so the “problem” seems to be related to the remote building system and/or defold communitypage
If you don’t mind I’ll gladly send you privately a package with the whole project, if you can see what wrong with your remote building system - that I actually love because it’s faster for sharing things with some beta tester
but beign working on jam page I’m less in a hurry - thanks
