Newbie question regarding building for iPhone 4 screen size

Solar2D General Questions/Discussion
#1

Forgive me with this newbie question but I have been having a play with the Corona 2.0 Beta 6 and following some tutorials. I have successfully created the standard hello world app and managed to get this on my iPhone 4 with its own icon. I am very pleased:)

Anyway I thought as a learning exercise I would try and make a sliding picture puzzle.

I created some tile images at 160 pixels by 160 pixels thinking the iPhone 4 screen is 640 pixels wide - hence 4 tiles across.

However when I test this on my iPhone 4 I can see it is displaying as if the screen resolution is 320 wide as I am only seeing 2 tiles across.

So do I have the wrong build settings or am I missing something really fundamental here?

Thanks

Currently the SDK only supports IOS 3 so the display is 320 by 480. We hope to have IOS 4 support in the near future. [import]uid: 7559 topic_id: 1528 reply_id: 4290[/import]

Thanks for the reply Tom.

Being new to Corona, I was very excited about this tool saving me from the pain of learning Objective-C (at least initially anyway). I will still need to devote time to get up to speed with Lua and the development tool so I am wondering if I should be concerned that there is no IOS 4 support and the fact your reply implies that this is not something that is currently being developed (apologies if I have misread this).

Can I ask if the absence of any speedier action developing an IOS 4 solution is related to the uncertainty regarding the new restrictions banning 3rd party tools creating iPhone content?

I am really hoping that I am not forced to have to slave over text books for months learning Objective-C etc as it seems such a backward step after enjoying the benefits of programming in Flash and Director for many years.

Best wishes

I’m pretty sure you can just use the config file or content scaling to fix the size issue…

Did you try a config file like this? From the way I understand it this should do the sizing properly AND size everything down nicely for the old 480x320 setups. But I don’t have an iPhone 4 to test on so I can’t confirm it works.

This file would be right in your app directory and called config.lua:

application =
{
content =
{
width = 640,
height = 960,
scale = “zoomEven”
},

Paul,

IOS 4 is on our road map and being worked on. We’ve been very busy with bug fixes and adding some features that have been requested here in the forums. If you have a feature that you feel is missing (like OS 4 support) please post it in the Feature Request section of the forum. Our goal is to support both IOS and Android.

Thanks,
