Very slow game on Iphone through Safari

Hi !

I'm making a small little game and, I tried to play it on my Iphone 4 through the Web browser, Safari.

It's quite slow.

On my PC, I have a dt of 0.016

On the Iphone, it's 0.1

So, my question is... is it normal ?

Is depending on my scripting ?

What's the problem ?

Thanks !!

Actually, When I putted the game in Fullscreen mode, it helps... but still slow...

i tested it on iphone os5 and the framerate is rather good, better than firefox on pc :) i get up to 0.040 / 0.050 , there are lot of improvements made from ios 4.0 to 5.0 concerning the browser/html5

also be carefull if you want to use sound, it will kill framerate to unusable > there is a workaround by somebody on the forum that was quite interesting, i will look it up

audio workaround

Yeah, are you using iOS 5? That's much faster.

Also, you have to remember mobiles have much weaker hardware than PCs. It looks like you're creating a lot of objects. Try putting in an object counter. You should try to keep it under around 50 objects on screen at any one time to have really good performance on a mobile. You have to specially design your games for mobiles - you can't assume any old game you make that runs well on your PC will run well on a mobile.

Yeah... I have a lot of object...

Is it really the number of objects, or the number of Sprites ?

Any object that draws to the screen, but Tiled Backgrounds still count as 1 even if they're big, so generally it's on-screen sprites.

IS it a limitation of Construct 2 ?

Or is it HTML 5

Is it something that will be improved, that can be ?

Or there always will be that limitation ?

For contruct I mean. (50-ish objects for this generation of smartphone)

Are you on iOS 5? vtrix said the framerate was fine on that. iOS 5 is much faster than iOS 4 so you should make sure you try it on iOS 5. It's neither Construct 2 nor HTML5 that is at fault, it's probably just that iOS 4 is slow.

how to put an object counter?
