Texture Compression with Texture Package

The rule :

 

 

DEFAULT CONFIGURATION FOR SCENE

CANVAS SCALER

  • SCREEN SPACE – OVERLAY
  • SCALE WITH SCREEN SIZE
  • 1536X2048
  • MATCH WIDTH OR HEIGHT
  • MATCH=1
  • REFERENCE PPU=1

CAMERA

  • SIZE=1024

IMAGE

  • PPU=1

 

EQUATION

PIXELS PER UNIT =(VERTICAL/(ORTHOGRAPHIC SIZE*2))

Configuration should be:

  • Sprite Renderer : 
    1. Glow : 32bit
    2. No Glow : Compress ETC 8bit
                                                            
  • Canvas :
    1. Glow : 32bit
    2. No Glow : Compress ETC 8bit

 

 

2 collection views in 1 view controller

Sunday, 17 July 2016 / Published in Android, Application, development

The idea:

We need to use 2 collection views in 1 view controller. First collection view has no header and the second has a header.

So we need to register header(nib) for the second collection view controller only.

 

 

 

 

By calling this code:

code1

best soccer dropping odds footballdroppingodds.com dropping odds movements and best football odds for today
today football predictions from the experts todayfootballpredictions.com best football predictions and betting tips

But the app crash after the above method invoke:

code4

code3

 

How you fix it?

 

Issues come from thie method below that set the header’s size for collection view:

(CGSize)collectionView:(UICollectionView *)collectionView layout:   (UICollectionViewLayout*)collectionViewLayout referenceSizeForHeaderInSection:(NSInteger)section

 

It will call the method below for providing header to all collection view:

(UICollectionReusableView *)collectionView:(UICollectionView *)collectionView viewForSupplementaryElementOfKind:(NSString *)kind atIndexPath:(NSIndexPath *)indexPath{

Note: our first collection don’t register the header class but the method invoke for providing header for the first collection view too.

 

You can fix it by providing the header’s size of the first collection view with size 0.

Example:

code4

Build on IOS running time…too long!!

Friday, 07 August 2015 / Published in Games, ios, Mobile, Mobilegames, Technology, unity, workflow

Hi,

Build on IOS running time : too long.

The workflow to build from unity to iOS device takes a lot of time. 10Mn, 20mn for some projects.

We got the issue with Frant’s garden also. It’s a lot of time. But the worst is when the build time from Xcode that takes forever. And the biggest issue is when all that is for nothing because you have a build Failed at the end just because some native plugin you have in your unity projects has not been copied properly during the xCode export.

Here is the solution : Post Processing script.

You have some example of what is it here for the curious:

We took some sample and we modify it to take care of our beloved native frameworks (monetizations frameworks ads like chartboost, vungle and other mediation stuff like mopub and so on.

One of the issues is also to setup properly the arc flag on some files, here is how it got working to add the proper compiler flag in xcode.

Thanks to the Install mod_pbxproj module from Python.

<code>
import mod_pbxproj
from mod_pbxproj import XcodeProject
project = XcodeProject.Load( pathToProjectFile + '/Unity-iPhone.xcodeproj/project.pbxproj')
# files that require ARC need to be handled here
filesThatRequireArc = [ 'FacebookNativeAdAdapter.m',  'UnityAdsMopubEvent.m', 'MPVungleRouter.m' ]
for arcFile in filesThatRequireArc:
temp = project.get_files_by_name( arcFile )
if temp:
buildFiles = project.get_build_files( temp[0].id )
if buildFiles and len( buildFiles ) > 0:
for buildFile in buildFiles:
syslog.syslog( syslog.LOG_ALERT, 'swapping ARC flag on for file: ' + temp[0].get( 'name' ) )
buildFile.add_compiler_flag( '-fobjc-arc' )
else:
syslog.syslog( syslog.LOG_ALERT, 'could not find file to switch compile type to ARC' )
</code>

Snippet for changing the language configuration from inside the app?

Friday, 07 August 2015 / Published in Android, Application, development, Mobile, Technology

 Change language in application

A usefull snippet if you want to change the locale of the app without having to go through the settings.

Configuration conf = getResources().getConfiguration();
 conf.locale = new Locale(iso3SupportLanguage[position]);
 DisplayMetrics metrics = new DisplayMetrics();
 WindowManager wm = (WindowManager) getActivity().getSystemService(Activity.WINDOW_SERVICE);
 wm.getDefaultDisplay().getMetrics(metrics);
 getResources().updateConfiguration(conf, metrics);
 Resources resources = new Resources(getActivity().getAssets(), metrics, conf);
 resources.updateConfiguration(conf, metrics);

Flow Layout in your face.

Friday, 07 August 2015 / Published in Android, Application, development, Technology

There is no native FlowLayout component, so for people. The following library gives a hand, but changing the space between category can be tricky, so we made it as default to get things done.

Take a look if you are interested:

Your apps is slow when building multi-dex

Friday, 07 August 2015 / Published in Android, Application, development, Technology

What is the problem?

Slow to build the app if the app is multi-dex (over 65K method). And the build time is taking more than 1mn.

 

What’s the solution?

We can configure to make build multi-dex faster. Your device just need to have Android Lollipop or up.

 

Configure gradle like below

android {
productFlavors {
// Define separate dev and prod product flavors.
dev {
// dev utilizes minSDKVersion = 21 to allow the Android gradle plugin
// to pre-dex each module and produce an APK that can be tested on
// Android Lollipop without time consuming dex merging processes.
minSdkVersion 21
}
prod {
// The actual minSdkVersion for the application.
minSdkVersion 14
}
}
...
buildTypes {
release {
runProguard true
proguardFiles getDefaultProguardFile('proguard-android.txt'),
'proguard-rules.pro'
}
}
}
dependencies {
compile 'com.android.support:multidex:1.0.0'
}

When building, select devDebug in Build variant
