iphone - How to launch a cocos2D game from single view app -


i created regular simple ios app (a single view application) 1 button , want launch cocos2d game ios app. in other words, want launch cocos2d game when press on button myapp.xib. don't want use url schemes launch game because require user download app download game. want user able launch game app internally. game want launch app:

http://www.raywenderlich.com/14439/how-to-make-a-game-like-fruit-ninja-with-box2d-and-cocos2d-part-3

i able add game dependency in xcode project. however, i'm not sure how go launching game app.

here's ideas had, didn't work me. there way can:

  • call app delegate of game (not app delegate of app) ibaction in app launch game?
  • call didfinishlaunchingwithoptions method of game (not didfinishlaunchingwithoptions of app) ibaction in app launch game?
  • call main.m file of game (not main.m of app) ibaction in app launch game?

from understand, these 3 different ways of launching ios app. keep in mind developing app (not game) allow user launch game above internally through app. ideally, nice (and easy) if can pushviewcontroller app game, i'm not sure if there easy way approach this.

is there anyway can launch game internally through app? advice, suggestions, sample source code appreciated.

short answer: yes

you need have 1 appdelegate (the 1 of ios app), , move there cocos2d init stuff. then, can launch game ibaction this.-

ccdirector *director = [ccdirector shareddirector]; [director pushscene:[yourfirstgamescene node]];  [director resume]; [self presentmodalviewcontroller:director animated:yes];

please, take next snippet example init/end cocos2d appdelegate

- (void) initcocos {     // create ccglview rgb565 color buffer, , depth buffer of 0-bits     ccglview *glview = [ccglview viewwithframe:[self.window bounds]                                    pixelformat:keaglcolorformatrgba8    //keaglcolorformatrgba8                                    depthformat:0    //gl_depth_component24_oes                             preservebackbuffer:no                                     sharegroup:nil                                  multisampling:no                                numberofsamples:0];      self.director = (ccdirectorios*) [ccdirector shareddirector];      self.director.wantsfullscreenlayout = yes;      // display fsp , spf     [self.director setdisplaystats:no];      // set fps @ 60     [self.director setanimationinterval:1.0/60];      // attach openglview director     [self.director setview:glview];      // rotation , other messages     [self.director setdelegate:self];      // 2d projection     [self.director setprojection:kccdirectorprojection2d];     //  [director setprojection:kccdirectorprojection3d];      // enables high res mode (retina display) on iphone 4 , maintains low res on other devices     if( ! [self.director enableretinadisplay:no] )         cclog(@"retina display not supported");      // default texture format png/bmp/tiff/jpeg/gif images     // can rgba8888, rgba4444, rgb5_a1, rgb565     // can change anytime.     [cctexture2d setdefaultalphapixelformat:kcctexture2dpixelformat_rgba8888];      // when in iphone retinadisplay, ipad, ipad retinadisplay mode, ccfileutils append "-hd", "-ipad", "-ipadhd" loaded files     // if -hd, -ipad, -ipadhd files not found, load non-suffixed version     //[ccfileutils setiphoneretinadisplaysuffix:@"-hd"];        // default on iphone retinadisplay "-hd"     [ccfileutils setipadsuffix:@""];                    // default on ipad "" (empty string)     //[ccfileutils setipadretinadisplaysuffix:@"-ipadhd"];  // default on ipad retinadisplay "-ipadhd"      // assume pvr images have premultiplied alpha     [cctexture2d pvrimageshavepremultipliedalpha:yes]; }  - (void) endcocos {     cc_director_end();     self.director = nil; }

actually, call initcocos before pushing director, , endcocos after closing game, like

appdelegate *appdelegate = (appdelegate *) [[uiapplication sharedapplication] delegate]; [[ccdirector shareddirector] dismissmodalviewcontrolleranimated:yes]; [appdelegate endcocos];

hope helps.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
