android - Libgdx: screen managaer -

good day sirs, i've started develop game uses lot of screens(introscreen,splashscreen,previewscreen,mainmenuscreen, etc.) , have encountered of following problem:

switching screen other screen unresponsive or buggy, , repeats same screen on , on again. have recycled button planned on using in different windows, visible in 1 of windows in other. implements screens screens, have abstract screen class because have seen in different sample codes extend screen class implements screen.

i'm quite confuse part, hope find proper solution problem.

is there way navigate or make more responsive screens?would improve performance of game create screenmanager?what instances should screenmanager have?

this code mainmenuscreen encounters problem button.

}

as other problem have encountered unresponsive screen, code previewscreen.

public class previewscreen implements screen {  private static dugmanmainclass game; private spritebatch batch; private orthographiccamera camera; private texture tx1 = assets.bgmenu; private bitmapfont font = assets.menufont2; private final static list<string> lines = new arraylist<string>();  private static int time = 0; private float temp = 0; private sprite s;   public previewscreen(dugmanmainclass game) {      this.game = game;      try     {         bufferedreader br = new bufferedreader(new inputstreamreader(gdx.files.internal("previewtext.txt").read()));         string line = "";         while ((line = br.readline()) != null) {             lines.add(line);         }         br.close();     }      catch(exception e)     {         e.printstacktrace();     }   }   @override public void render(float delta) {     float w = s.getheight();      gdx.gl.glclear(gl20.gl_color_buffer_bit);      temp += gdx.graphics.getdeltatime();       while(temp>1.0f/60.0f)     {         previewscreen.tick();         temp -=1.0f/60.0f;          s.setu(temp+1f);         s.setu2(temp+1f);      }          batch.setprojectionmatrix(camera.combined);     batch.begin();     s.draw(batch);      int yo = time / 4;        (int y = 0; y <= s.getheight() / 12; y++)      {         int yl = yo / 12 + 420 / 12 - y;         if (yl >= 0 && yl < lines.size())          {             font.draw(batch,lines.get(yl), (800 - 30 * 12) / 2,  y * 12 + yo % 12);          }     }      batch.end();    }   @override public void show() {      batch = new spritebatch();      float w = 800;     float h = 420;      camera = new orthographiccamera();     camera.settoortho(false, w, h);      tx1.setwrap(texturewrap.repeat, texturewrap.repeat);      s = new sprite(tx1);     s.setposition(0, 0);       assets.bgsound3.play(1f);     // todo auto-generated method stub  }   @override public void dispose() {      assets.dispose();  }  public static void tick() {     time++;      if (gdx.input.iskeypressed(keys.enter) || gdx.input.istouched()) {         game.setscreen(new splashscreen(game));         assets.bgsound3.stop();     }      if (time / 4 > lines.size() * 10 + 250) {           game.setscreen(new splashscreen(game));         assets.bgsound3.stop();     }  } 

}

when receives input or finishes displaying texts, set screen splashscreen , after splash proceed intro , mainmenu, vice versa.

i see few things concerning, first focus on issue @ hand:

private static int time = 0; 

you using static variable in screens , seem reset them 0 when press button on mainmenuscreen. means next time display screen, value result in screen switch , flip , forth forever (and cause lot of lag).

other issues:

you storing considerable amount of static state in code, frowned upon. here post (refer section on implications) talks issues related it. programming guides advise against it.
