actionscript 3 - Correct method of incorporating Starling with Preloader -

-

hi know best method of adding preloader. when content loaded create instance of starling framework. here have:

import flash.display.loader; import flash.display.sprite; import flash.events.event; import loaders.preloader; import starling.core.starling;      //main class container  public class game extends sprite  {     //preloader class     private var _loader:preloader;      //starling instance     private var _starling:starling;      //constructor initialise game     public function game():void      {         this.addeventlistener(event.added_to_stage, onaddedtostage)     }      private function onaddedtostage(e:event):void      {         this.removeeventlistener(event.added_to_stage, onaddedtostage);          _loader = new preloader();         addchild(_loader);          _loader.addeventlistener("loaded_game", ongameloaded);     }      private function ongameloaded(e:event):void      {         trace("game loaded");         _starling = new starling(game,stage,null,null,"auto","baseline");         _starling.start();     }  }

this preloader class:

package loaders { import flash.events.event; import flash.display.sprite; import flash.text.textfield; import flash.text.textfieldautosize;  public class preloader extends sprite {     private var textloaded:textfield;      public function preloader()     {         this.addeventlistener(event.added_to_stage, onaddedtostage);     }      private function onaddedtostage(event:event):void     {         // remove added stage listener         this.removeeventlistener(event.added_to_stage, onaddedtostage);          textloaded = new textfield();         textloaded.x = 300;         textloaded.y = 300;         textloaded.border = true;         textloaded.autosize = "center";         addchild(textloaded);          //loop current load state         this.addeventlistener(event.enter_frame, loadgame);         this.addeventlistener(event.removed_from_stage, onremovedfromstage);     }      private function onremovedfromstage(event:event):void {         this.removeeventlistener(event.enter_frame, loadgame);         this.removeeventlistener(event.removed_from_stage, onremovedfromstage);     }      private function loadgame(e:event):void     {         //vars         var total:number = parent.stage.loaderinfo.bytestotal;         var loaded:number = parent.stage.loaderinfo.bytesloaded;          textloaded.text = math.floor((loaded/total)* 100) + "%";          if (total == loaded)         {             this.removeeventlistener(event.enter_frame, loadgame);             dispatchevent(new event("loaded_game", true));         }     }  }//end of class

}

is best way of doing or there more efficient, practical option? can see making use of flash classes before instantiate starling? preloader textfield listing loaded, should allow application load faster.

don't think make more sense create external swf preloads game? better solution incorporating preloader main game file.

i use sonar plugin executes if activated in maven profile. sonar runs on every compile. the problem build fail other team members not have sonar application installed locally. pom.xml checked in team members same copy including sonar configuration, don't want them modify purpose of disabling sonar (they might inadvertently check modified copy in). please advise how configure maven (.m2/settings.xml) and/or pom.xml sonar feature can enabled/disabled local profile. here sonar configuration in each project's pom.xml: <plugin> <groupid>org.codehaus.mojo</groupid> <artifactid>sonar-maven-plugin</artifactid> <version>1.0</version> <executions> <execution> <id>make-sonar</id> <phase>compile</phase> <goals> <goal>sonar</goal> </goals> </execution> </executions> ...

python - TypeError: can only concatenate tuple (not "float") to tuple -

-
i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...

this question has answer here: meaning of .this , .class in java 2 answers i'll straight point. im still learning bit of syntax , want know difference between code is code a: public class buttonz extends jbutton{ public buttonz(){ settext(new string(string.valueof(i))); } } please ignore fact i undeclared, not lost. code b: public class buttonz extends jbutton{ public buttonz(){ settext(new string(string.this.charat(i))); } } what don't yet understand difference in typing string.this , string. i under assumption when use dot operator on class accessing it's static methods(and/or variables if they're not hidden). i have studied little bit , have concluded when using string. accessing string static methods.. when using string.this. i'm accessing methods class buttonz extendi...
