LibGDX doesn't scale properly on iPhone 6+ or iPhone 6 in zoomed mode #2356

PaulMaxime · 2014-09-20T17:28:53Z

in IOSGraphics.java, the code only handles device scale == 2. Since the 6+ has scale of 3, games are shrunk to a corner of the screen in the 6+. We need to modify this to simply multiply by the scale in all cases.

There is also a perhaps more subtle bug on the iPhone 6 in "zoomed" mode. In a similar way, the game is restricted to a corner of the screen. Not exactly sure here what the fix is, still diagnosing it.

Bumping this, since this is one of the critical issues that needs to be prioritized.

johnnyapol · 2014-09-21T14:23:11Z

The team is aware of this issue and we are working on a solution.

johnnyapol · 2014-09-21T14:24:06Z

Going to reference #2350 as these are very related.

PaulMaxime · 2014-09-21T15:13:45Z

Make sure you check zoomed mode. There is a nativeScale method on UIScreen in 8 that returns a non-integer value in zoomed mode. You'll need to use it instead of scale on 8.

I'm currently busy figuring out RoboVM issues on iOS 8. Once we have that
fixed i'll fix this one up.

Hi
I had this problem in my landscape game. I made an ugly workaround and the game works in native resolution (not in zoomed mode) im all devices in iOS8.

I created a new IOSApplication.java as suggested in http://www.badlogicgames.com/forum/viewtopic.php?f=11&t=16401#p70299
and added this code

switch (orientation) {
        case LandscapeLeft:
        case LandscapeRight:
            height = (int)bounds.width();
            width = (int)bounds.height();
              if(width < height){  // workaround
                    width = (int) bounds.width(); // workaround
                    height = (int) bounds.height(); // workaround
                            } // workaround
            break;
        default:
            // assume portrait
            width = (int)bounds.width();
            height = (int)bounds.height();
        }

then I created custom launch images for iPhone 5/5S, iPhone 6, iPhone 6 Plus and iPhone 4s:

File Name	Resolution	Device
Default-568h@2x.png	640 x 1136	iPhone 5/5s
Default-667h@2x.png	750 x 1334	iPhone 6
Default-736h@3x.png	2208 x 1242	iPhone 6+
Default.png	320 x 480	iPhone 3gs
Default@2x.png	640 x 960	iPhone 4/4s
Default@2x~ipad.png	1536 x 2008	iPad < iOS8
Default~ipad.png	768 x 1004	iPad < iOS8
Default8@2x~ipad.png	2008 x 1536	iPad iOS8
Default8~ipad.png	1004 x 768	iPad iOS8

I specified these files in Info.plist.xml :

Can confirm using nativeScale (available in iOS 8) fixes this issue on the normal iPhone 6 in zoomed mode. I don't have a 6+ to test with, however, and the sim isn't launching for the 6+.

badlogic · 2014-09-23T19:53:00Z

Hey folks, i hope i cam fix this up tomorrow. We've been busy getting
RoboVM up to speed with iOS 8, which we finished today. Should be able to
fix this up properly tomorrow.

RoboVM doesn't yet expose the nativeScale method. Will fix this as soon as that's done on the RoboVM side.

magfort · 2014-09-26T05:17:23Z

Could anyone explain how they're using native resolution/nativeScale in the mean time?

I've been receiving complaints from iPhone 6 users that the scale in my game is wrong and I'm not really sure how to fix this.

Can confirm that building this morning with

gdxVersion = '1.3.2-SNAPSHOT'
roboVMVersion = '1.0.0-alpha-02'

fixed the issue for me. Thanks!

ChetRippo · 2014-09-30T18:18:48Z

Worked for me as well!

perchi · 2014-10-01T21:16:40Z

With the latest nightly build i have problems with input events (clicks) which are not workig! Anyone else have similar problems (on iOS 8)? Tnx!

ext {
gdxVersion = '1.3.2-SNAPSHOT'
roboVMVersion = '1.0.0-SNAPSHOT'
}
touch events were working on version 1.3.0 ... but there is a problem with rotation and screen size ... so what to do? :D

perchi · 2014-10-01T22:43:11Z

This is happening only on iOS devices ... on Android and Desktop is working as expected ...

Tom-Ski · 2014-10-02T11:52:46Z

Please create a new issue with an executable example that reproduces your problem.

Closing this out.

magfort · 2014-10-03T04:29:05Z

Was this commit intended to fix the issue? 062de10

The commit comment suggests it was just preparing for the fix, not fixing it.

in iosrobovm/IOSApplication.java
line 123: scale is always equal to 2.0f due to the condition on line 120 so the change in this commit has no effect.

On the iPhone 6 Plus, my app still only fills 2/3 of the width and 2/3 of the height.

Am I missing something or is this issue not actually fixed?

badlogic · 2014-10-03T06:53:09Z

Zoomed mode has not been fixed as RoboVM lacks a binding to the nativeScale
method.

magfort · 2014-10-03T09:20:30Z

I've made the following change locally and it seems to solve this issue:
removed line 120 and 131-140 of https://github.com/libgdx/libgdx/blob/master/backends/gdx-backend-robovm/src/com/badlogic/gdx/backends/iosrobovm/IOSApplication.java

Is there a problem with this simple solution? I've tested it across all iOS 8 devices in the simulator and each has the correct scaling with the fix. Without the fix, the iPhone 6 Plus is the only one scaled incorrectly.

badlogic · 2014-10-03T15:12:48Z

OK, this is all kinds of fucked it seems. I can get the nativeScale now (conditional on OS version). On iOS 8 on an iPhone 6 (plus) i get funky black bars to the left and right. UIScreen.getMainScreen().getBounds() reports 480x320, the scale is 3 on an iphone 6 plus, resulting in a width/height of 1440*960, on an iPhone 6 the scale is 2 resulting in 960x640 pixels scaled.

This introduces funky black bars: http://libgdx.badlogicgames.com/uploads/Screen%20Shot%202014-10-03%20at%2017.11.41-CRQw8sLJcg.png

I know nothing about iOS UI programming, anybody got an idea?

badlogic · 2014-10-03T15:16:32Z

So, here's the commit with the latest "fixes" 5f28c1f No idea how to get the proper native screen resolution. Both scale and nativeScale return integer values, resulting in wrong pixel resolution and hence the black bars of death. Any hints appreciated.

badlogic · 2014-10-03T15:18:55Z

@ericnondahl right, the problem is that the point sizes are wrong for iPhone 6(+). They stay at 480x320. I hope we don't have to add a launch screen...

badlogic · 2014-10-03T15:34:06Z

OK, launch images do the trick and let our apps run in "native" resolution. What a stupid trick...

Fixed with the latest commit, should be available in the nightlies soon.

magfort · 2014-10-04T07:03:11Z

It's all working for me with latest nightly.
