Just had two friends test it on their machines (PC and mac), both reported ~100ms input lag.

As I said before, it's very annoying that it seems there's no way to actually measure input lag. Is this true? or is there some way to do it?

And yes, as Aurel rightly points out, the game looks like absolute trash visually at anything lower than 60fps. I think the official statement here is that this issue was fixed in Canary but there are clearly still severe issues. I'm still getting HUGE dt variance in Airscape in Canary. I'll try to get a minimal repro together of that in C2, since the Airscape issues are waaay worse than the issues in the demo, and I have no idea why. This seems to be a recurring issue, as Aphrodite and Aurel could also point out - real games for some reason struggle a lot more with amplified versions of the problems created by this issue.

In a nutshell, here's the issue:

• In Chrome, low FPS sometimes gives very noticeable input lag.
• This input lag only occurs when the GPU is the bottleneck. CPU lag has no effect. Specifically, it seems to be tied to fillrate.
• To try the issue for yourself, click here in Chrome or download the attached capx.
• The issue remains in Chrome Canary. In testing with Airscape, Canary actually gives far worse input lag.
• In firefox, there's no input lag. In IE, there maaaay be a tiny little bit, but that could be my imagination.

These factors lead me to assume that the input lag issue might be related to these issues.

It appears that the input lag is partially dependent on other factors not explored in my demo, as in Airscape the lag is far greater at equal FPS. I can't really confirm this easily though.

In the capx, the red line indicated reported FPS, and the green line is 1/dt. These values should be basically identical (allowing for a slight bit of variance).

One thing to note is that there's (AFAIK) no way to objectively and accurately measure input lag. Anyone know of a way?

Any thoughts about this whole issue? Any way we could get a repro to the Chrome people, and tell them that they are performing far worse than IE and firefox in this regard?

Cheers!

Weird, I've never seen anything like that before. Are your graphics drivers up to date? What GPU do you have?

I believe offsite hosted games show a roll of Scirra related ads beforehand which helps pay for hosting of the game on the arcade. I'm assuming allowing for this is in the TOC of uploading to the Arcade, but yeah, maybe Scirra will want to have a look at changing it for the upcoming Arcade update since it's definitely weird to see your game hosted on tons of shady sites.

— Cranberry linked me to your share plugin, which I hadn't seen. Would that work? I'm assuming because you linked me to cranberry it won't work, but I don't see any reason it wouldn't, at least from your description.

Hey Cranberry, quick question for you - Would the shareapp plugin allow me to do what is mentioned in this topic?

Is there documentation or something that I'm missing?

Cheers!

saiyadjin Unfortunately I have no idea how to write a plugin for C2... I really don't know any javascript

— I didn't see anything relevant to Twitter sharing in CranberryGames' plugins.

Hey all,

I'm experimenting with making a little mobile game, just for fun (and to see what C2 can do on mobile these days)

A lot of games these days have the great marketing strategy of allowing a user to tweet a screenshot at the end of every level/playthrough etc, along with some text, like 'I scored 1357 in [Game name here]!'

I've looked at the Twitter plugin, but I don't really see anything along those lines. I also don't want to use the default Twitter button, but to make my own.

Anyone with more experience than me know if this is possible?

Cheers!

I was going to say the same thing as Ashley, but global layers have the same problem as global objects - what if you only want this layer in, say, half your layouts? you're stuck. (AFAIK anyway)

Yeah, it's pretty annoying to have to go into the XML and manually copy layers around.

Yes please! Especially for text, dealing with a top-left hotspot is really annoying when the text is left-aligned.

Well I know that Chrome 38 has some serious Vsync issues, and the new NW is based on Chrome 38 so I don't really want to risk it, unless I hear someone who has seen a definite improvement over previous NW builds.
