Gideros on the new iPad

phongtt · March 2012

A quick info for those who haven't had a chance to check Gideros games on the new Ipad:

My game (Number Rush) version 1.0.0 runs just fine on it.
The device automatically scales to fit the fullscreen although I didn't prepare retina assests for it.

A few days ago v1.1.0 of the game was live on the appstore, it still runs fine but it only displays on 1/4 corner (top-left) of the device.
It turns out that we made a mistake by forgetting to disable the Retina option in project properties in Gideros IDE.

Hope it helps some of you to prevent future mistake like this.

You had to disable that options for the "New IPad"? I thought you need to set it.

I mean for ipad games that are not retina-ready, if we mistakenly set retina enable in Gideros properties, the new ipad will display the game at the top-left corner (one fourth of the screen). On the other hand, if retina setting is disabled, the game is automatically scaled up to fill the full screen of the new ipad. That makes sense, don't you think so?

Actually, I had the same problem, that's why my latest game had the approval delayed: I had it developed with "No Scale - Center" (and I guess you had it at "No Scale- Top Left)" in order to have it working for iPhone & iPad, but that was a mistake. The right setting turned out to be "Pixel Perfect", and Retina enabled.

Is there a setting that will give you a universal build that will work across all devices? ie. 3GS -> 4(S) and iPad2 -> "new" iPad.

Ideally you'd have image.png for the 3GS, image@2x.png for the 4(S) and the iPad2 and image@4x.png for the "new" iPad.

Gideros doesn't support universal builds. You "might" be able to change the XCode project in a way that you get a universal build. The question is, it that reasonable.

@mykyl66 wrote a nice blog post about why you can run into problems with universal builds and the "new" Ipad.

The @4x would only work if the base size is 320x480: personally I prefer to set it at 640x960 (that looks like the best compromise right now), so the new iPad would be @2x, and the "old" 3GS would get @half (but, I actually never bothered, the 3GS scales down pretty well, and my games weren't so graphic-hungry that I should worry about).
As per the "universal" build, all my apps are, on Xcode is just a flag (plus a few details like icons & launch images): the real challenge is to get the Gideros settings right!

@pmanna: I would love it if you could write something about the right settings into the Ultimate guide. This way it won't get lost inside the forum.

@pmanna - I second that

Sorry for double posting - is there any easy way for me to delete this post?

@techdojo - Unfortunately not. I constantly monitor the forum and do that for you, in case you are stuck.

I tested the Bird example on iOS simulator with iPhone & iPad and both retina.

Setting Stretch & "Retina for iPhone" for the Gideros project does the job.
Exported for iPhone, and modified the Xcode setting to "Universal" seems to work fine if you like to have a universal iOS app.

The problem is setting stretch and "Retina for iPad" might look the same, but I guess
running in non retina mode on the new iPad is faster
