java - Custom Animation end trigger -

-

i'm writing "space invaders" style app , needed move stop repeat animation classic game. got processes go 1 way, using code below, when want go back, there not seem easy way this. think easiest way have happen on end animation event, cannot event trigger, when calling super.end();. i've looked around way trigger event manually no avail. way doing may little sketchy works enough right try , make work way.

public void start() {     if(begin < end) //recursive end condition     {          int distance = interval + begin; //change distance traveled         //create new animation part of whole animation         objectanimator anim = objectanimator.offloat(toanimate, property, begin,distance);         timeinterpolator inter = new timeinterpolator() //makes animation move 1 frame         {             public float getinterpolation(float prog)             {                 return math.round(prog * 10) / 10;             }         };         anim.setinterpolator(inter);         anim.setduration((long)(500));         anim.addlistener(new animatorlistener()         {             @override             public void onanimationstart(animator animation){}             @override             public void onanimationend(animator animation)             {                 start(); //start next part of movement             }             @override             public void onanimationcancel(animator animation){}             @override             public void onanimationrepeat(animator animation){}         });         begin = begin + interval; //update end recursion value         anim.start(); //begin animation     }     super.end(); //this doesn't work... rip } 

public void start() {     if(begin < end) //recursive end condition     {          int distance = interval + begin; //change distance traveled         //create new animation part of whole animation         objectanimator anim = objectanimator.offloat(toanimate, property, begin,distance);         timeinterpolator inter = new timeinterpolator() //makes animation move 1 frame         {             public float getinterpolation(float prog)             {                 return math.round(prog * 10) / 10;             }         };         anim.setinterpolator(inter);         anim.setduration((long)(500));         anim.addlistener(new animatorlistener()         {             @override             public void onanimationstart(animator animation){}             @override             public void onanimationend(animator animation)             {                 begin += interval;                 if(begin < end){                    start(); //start next part of movement                 }                 else{                     // else                 }             }             @override             public void onanimationcancel(animator animation){}             @override             public void onanimationrepeat(animator animation){}         });         anim.start(); //begin animation     } }

java - Custom OutputStreamAppender not run: LOGBACK: No context given for <MYAPPENDER> -

i wish write custom appender on basis of outputstreamappender . wrote following class package tests; import java.io.ioexception; import java.io.outputstream; import ch.qos.logback.core.outputstreamappender; public class myappender<e> extends outputstreamappender<e> { public myappender() { system.out.println("myappender created"); setoutputstream(new outputstream() { @override public void write(int b) throws ioexception { throw new unsupportedoperationexception(); } }); } } then wrote following runner: package tests; import org.slf4j.loggerfactory; import ch.qos.logback.classic.logger; public class runner { private static final logger log = (logger) loggerfactory.getlogger(runner.class); public static void main(string[] args) { //log.addappender(new myappender<iloggingevent>()); log.info("hello world"); } } finall

java - UML - How would you draw a try catch in a sequence diagram? -

Image
is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge
