### Re: GameMaker:HTML5 - Things that work differently

Work has begun on an extension to emulate 39DLL with Node.js and Socket.io. The idea is that it should drop into 39DLL games with little or no modification required for HTML5.

http://gmc.yoyogames.com/index.php?showtopic=520438

Seems that YoYo's bug wrangling has slowed considerably. 1.0.114 should be coming within the next 24 hours.

UPDATE:

Errr. Another 24 hours.

### Re: GameMaker:HTML5 - Things that work differently

Ahhh, this may be a clue as to why things slowed down yesterday.

Wow! That sounds really really interesting. Didnt see that one coming. This will be a nice feature to mess around with.

### Re: GameMaker:HTML5 - Things that work differently

Indeed. Apparently Uriel Griffin has already made an Box2D extension, so physics would appear to be coming one way or another.

It's unclear if Uriel plans (or planned) on releasing it publicly but I suspect he would.

In response, Mike hinted at some interesting possible functionality:

My bug is still unattended. This is quite a bit of a problem, as the bug is not visible and might hit someone without expecting it.

It is visible but it has fallen to the fourth page with ten other unassigned bugs. I count 89 unassigned bugs in total.

With "visible" I meant the bug in gamemaker, not the bug report lol ..

The bug gives no error, or other failure.. It fails silently, and in some cases user might think it is their fault ("did I accidentally type double {\\\} somewhere?").

edit:*great* forum software doesn't allow backslashes between spaces

### Re: GameMaker:HTML5 - Things that work differently

That is a really strange forum bug. It only seems to happen when a post contains both a left and a right square bracket somewhere within it. Position and order doesn't seem to matter but both must be present somewhere. Surely related to BBCode handling. It took me ten minutes of successfully posting slashes to figure that out.

These slashes / // \ \\ are fine.

These slashes / // \ \\ are not fine.

This bracket ] is nothing special and neither is this one [ ... but together they create chaos!

### Re: GameMaker:HTML5 - Things that work differently

Since GM:HTML5 is billed as a program accessible to people that don't know code, it seems odd having no in-built way of changing the HTML page exported when you export your game to HTML5 - bar a few very limited GML options you're stuck with the game at the top left of a plain grey background.

My suggestion would be to use the basis of Game Information (since removed) as an editor of that Index page. A lot of the stuff is already there - background colour changing, font size/typeface/colour changing and text inputting, and horizontal alignment.

Vertical alignment, images (taken from Sprites), textured backgrounds (taken from Backgrounds), and hyperlinks could be added, along with of course a little element that basically means "plonk game here".

Failing that, have an external editor that does this stuff with an already-exported index.html.

Fixed in v1.0.114 - on Game Information I have added an HTML5 tab this allows you to select one of the included files as the index file to use when Running or Debugging.

### Re: GameMaker:HTML5 - Things that work differently

I'll dump some more of today's revelations here. I'm being recklessly optimistic that there will be more than one so I'm making a bullet list. Living on the edge!

• [GM:HTML5 does not support splash videos and that will probably remain the case. It should be possible to make a JS extension to play HTML5 videos provided by the user. I wonder if it would be possible to make horrible FMV-style games?

• Games must be run from a web browser. It would appear this is because of image caching operations that must be performed to support limited color blending (image_blend, text color, etc). Browsers only support web storage for domains, not for pages served from the local file system.

It seems some cross-browser hiccups have slowed things down today. No update until tomorrow.

### Re: GameMaker:HTML5 - Things that work differently

Yeah, very nice...

Did anybody else notice that movement by pixel got sloppy with the latest version?
I had a project in 1.0113 which ran just fine...now in 1.0.118 the movment on some coordinates in the room is sloppy.... I#ve seen other reports on this too.
Maybe even the round() function is buggy.... very saddening

### Re: GameMaker:HTML5 - Things that work differently

If GM:HTML5 uses web storage for its persistent file operations (INI files for instance), and storage is allocated based on the domain or subdomain of the page being viewed, and storage is limited to 5MB for each allocation, it seems like a portal site serving up multiple games could cause the user to quickly expend the available storage unless each game existed within its own subdomain. Do browsers even supply a user interface for managing web storage?

I don't know if it is related, but I do know there has been some difficulty implementing round() within the HTML5 runner. I wrote a bit about that here.

I cant even test in HTML5 cause I am using bbox_ variables which dont work in HTML5 yet. So, I get this problem in the windows version.

Are you're saying the behavior of Windows games has changed? That seems very odd.

Well, I can only tell you what I experienced.

I posted the engine on the bug tracker.

I definetly experienced this in 1.0.118 but NOT in 1.0.113

### Re: GameMaker:HTML5 - Things that work differently

Russell just told me that Box2D physics will be available to HTML5 and Windows executables! I had initial expected this to be an HTML5-only feature. It will be a standard feature for this and future versions of GameMaker. It will not be coming to GM8 Lite and Standard.
