I have tested but it fails.

Websocket sends handshake message then immediately closes connection. Server receives handshake message but cant response.

Error message : timeout.

Dungeons test...

I got around to testing my new prototype which uses Noobhub, and I get this message (same as @mertocan most likely):

WebSocket connection to 'ws://46.4.76.236:1337/' failed: WebSocket is closed before the connection is established.

Any idea on how to get this up running?

totebo · November 2015

Found this, but none the wiser:

I'll do some tests too, but I need to find/install a web socket server somewhere. Is Noobhub websocket aware ?

ar2rsawseen · November 2015

@hgy29 you can use official websocket echo server:
https://www.websocket.org/echo.html

totebo · November 2015

Not sure about Noobhub and websocket. A question for @overtorment.

Overtorment · November 2015

No, its not aware of web sockets.
Websocket protocol is built on top of TCP, right? Should be easy enough to make it compatible

ar2rsawseen · November 2015

HTTP is build on top of TCP and WebSocket are built on HTTP to emulate TCP. Makes sense, right?

But there are lots of npm modules to provide Websocket functionality

hgy29 · November 2015

I didn't try yet, but at least we know why it didn't work with Noobhub at least :P

Overtorment · November 2015

If anyone would make Noobhub compatible with Websockets that would be awesome, because that would mean that HTML5 app would be able to communicate with native Gideros apps (ios/android/etc). And not only that - with any engine noobhub ported on (coronasdk, love2d etc).

totebo · November 2015

I concur. That would be AWESOME!

A quick demo of upcoming vector graphics:
http://apps.giderosmobile.com/path2d/

Current features:
- Support for quadratic and cubic curves
- Support for antialiased outline

Lua code (API subject to change):

local s=Path2D.new()
local pstr={0,0,100,100,300,300,400,400}
s:setPath("ML*Z",pstr)
--s:setPath("MCZ",{0,0,400,0,400,600,0,600})
--s:setPath("MC*Z",heart)
s:setFillColor(0xFF0000,0.7)
s:setLineColor(0x0000FF,0.7)
s:setLineThickness(10)
s:setPosition(100,100)
--s:setScale(3)
 
stage:addChild(s)
 
t=0
local frame = 0
local timer = os.timer()
local function displayFps()
	frame = frame + 1
	if frame == 60 then
		local currentTimer = os.timer()
		print(60 / (currentTimer - timer))
		frame = 0
		timer = currentTimer	
	end
end
 
stage:addEventListener(Event.ENTER_FRAME,function()
 
displayFps()
t=t+1
pstr[3]=math.sin(t/50)*400+100
pstr[4]=math.cos(t/50)*400+100
pstr[5]=math.sin(t/20)*400+300
pstr[6]=math.cos(t/20)*400+300
s:setPath("MCZ",pstr)
end)

yubaro · November 2015

Amazing. Is this feature will come in a future release of Gideros?

MatthewCedo · December 2015

This topic is interesting

SinisterSoft · December 2015

@yubaro Yes. It works great - I'm going to use it in my next game.

hgy29 · December 2015

Guys, I've just finished Facebook plugin for HTML5. I'll have a look at ads now!

SinisterSoft · December 2015

@yubaro See this thread for an example of Path2D working in a game idea...

unlying · December 2015

Not working for me in Mozilla Firefox. Working at local, but not working remotely. Working well in Chrome and IE.

hgy29 · December 2015

Hi @unlying, the issue you encountered with FF is explained there: http://stackoverflow.com/questions/22956440/cannot-open-indexeddb-in-firefox

Gideros HTML5 export uses indexedDB for its persistent storage, but FF only make it available on either main page, or an iframe with a URI reference, whereas your game on kongregate is embedded within an iframe without URI reference:

<iframe allowfullscreen="allowfullscreen" class="dont_hide" border="0" scrolling="auto"
style="margin-top: 0px; left: 70px;" name="gameiframe" id="gameiframe" 
frameborder="0" height="640" width="480">
</iframe>

Of course Gideros should detect that IndexedDB is not available and disable persistant storage instead of just bailing out, but that will mean that your app won't be able to save data in |D| folder of gideros.

I'll have a go at properly handling IndexedDB availability.

SinisterSoft · December 2015

@hgy29 When you put it in, will you return false when the file is attempted to be created (and fails) - so a check can be made from the Lua side.

hgy29 · December 2015

Yes, for sure!

hgy29 · December 2015

@SinisterSoft, I changed my mind: for best compatibility with existing apps I think it is best if file creation doesn't fail. Files will just be lost on relaunch. But... yes we need some way to detect this so the app can warn the user.

What would you suggest ? What do other thinks ?

SinisterSoft · December 2015

I think in the existing system (android,ios) it does fail if the file isn't created or able to be read doesn't it?

eg:

	local file=io.open("|D|clan.txt","w+")
	local saveString=json.encode(clan)
	if file then
		file:write(saveString)
		file:close()
	end

and

	local file=io.open("|D|clan.txt","r")
	if file then
		local originaldata=file:read()
		if originaldata then
			clan=json.decode(originaldata)
		end
	end

hgy29 · December 2015

Ok, I did it that way after all: if the browser or context doesn't allow local storage (either iframe without URI, non compliant browser or private browsing), then any attempt to open/create a file in |D| will result in 'nil' being returned.

ar2rsawseen · December 2015

Hello, we started experimenting with ads and as a first try we tried Google Adsense.
Any suggestions for other ads to use on the Web, that you would want to see integrated in Gideros?

kinrpg · December 2015

Regards,
I have recently studied the genre and produced apps on it. Very good, and I love Lua

too. But I'm having a problem, I am not able to export the project to HTML5. When the command to export it to "Template not found" message. Does anyone know why and how to proceed or whether it is a feature that has to buy?

Tanks

hgy29 · December 2015

Hi @kinrpg,

HTML5 export is still in development, general release is due somewhere between february and june. Only people who have financially contributed to the development is this new export target have access to the in-development version. See the kickstarter page for better understanding.

SinisterSoft · December 2015

@hgy29 Maybe people who missed the kickstarter could 'buy' in via a Paypal donation to you and get it before release?

hgy29 · December 2015

Sure, better late contribution than none

MP me if interested.
