android - Loading AutoParallaxBackground Andengine Texture -


i'm rookie in andengine . working simple andengine game project , want load parallax background . follow step nicolas gramlich shows in parallax background example . got problem after running code saw black screen blinking colors

i think problem buildabletextureatlas , parallaxtexture here code resourcemanager class 

public itiledtextureregion playertiledtextureregion; public itiledtextureregion enemytiledtextureregion; public itextureregion platformtextureregion; public itextureregion cloudonetextureregion; public itextureregion cloudtwotextureregion; public itextureregion cloudthreetextureregion;    private buildablebitmaptextureatlas gametextureatlas;   public bitmaptextureatlas mautoparallaxbackgroundtexture;  public itextureregion mparallaxlayerback; public itextureregion mparallaxlayermid; public itextureregion mparallaxlayerfront;  //sounds sound soundfall; sound soundjump;  //music music music;  //font font scorefont;

here loadresource() method 

public void loadresources(){     bitmaptextureatlastextureregionfactory.setassetbasepath("gfx/");      gametextureatlas = new buildablebitmaptextureatlas(mgameactivity.gettexturemanager(), 1024,             512,bitmaptextureformat.rgba_8888,textureoptions.nearest_premultiplyalpha);      playertiledtextureregion = bitmaptextureatlastextureregionfactory.createtiledfromasset(gametextureatlas,mgameactivity.getassets(),              "player.png", 3, 1);     enemytiledtextureregion = bitmaptextureatlastextureregionfactory.createtiledfromasset(gametextureatlas, mgameactivity.getassets(),             "enemy.png", 1, 2);     cloudonetextureregion = bitmaptextureatlastextureregionfactory.createfromasset(gametextureatlas, mgameactivity.getassets(), "cloud1.png");     cloudtwotextureregion = bitmaptextureatlastextureregionfactory.createfromasset(gametextureatlas, mgameactivity.getassets(), "cloud2.png");      platformtextureregion = bitmaptextureatlastextureregionfactory.createfromasset(gametextureatlas, mgameactivity.getassets(), "platform.png");      mautoparallaxbackgroundtexture = new bitmaptextureatlas(mgameactivity.gettexturemanager(), 1024, 512);     mparallaxlayerfront = bitmaptextureatlastextureregionfactory.createfromasset(mautoparallaxbackgroundtexture, mgameactivity, "parallax_background_layer_front.png", 0, 0);     mparallaxlayerback = bitmaptextureatlastextureregionfactory.createfromasset(mautoparallaxbackgroundtexture, mgameactivity, "parallax_background_layer_back.png", 0, 188);     mparallaxlayermid = bitmaptextureatlastextureregionfactory.createfromasset(mautoparallaxbackgroundtexture, mgameactivity, "parallax_background_layer_mid.png", 0, 669);       try{         gametextureatlas.build(new blackpawntextureatlasbuilder<ibitmaptextureatlassource, bitmaptextureatlas>(2, 0, 2));          /*gametextureatlas.load();*/         mautoparallaxbackgroundtexture.load();      }catch(final textureatlasbuilderexception e){         e.printstacktrace();         throw new runtimeexception("error while loading textures", e);     } }

now gamescene class

scene scene = new scene();     autoparallaxbackground autoparallaxbackground = new autoparallaxbackground(0, 0, 0, 5);     autoparallaxbackground.attachparallaxentity(new parallaxentity(0.0f, new sprite(0, 200, resmanager.mparallaxlayerback, resmanager.vbom)));     autoparallaxbackground.attachparallaxentity(new parallaxentity(-5.0f, new sprite(0, 80, resmanager.mparallaxlayermid, resmanager.vbom)));     autoparallaxbackground.attachparallaxentity(new parallaxentity(-10.0f, new sprite(0, 400, resmanager.mparallaxlayerfront, resmanager.vbom)));     /*sprite cloud1 = new sprite(200,300, resmanager.cloudonetextureregion, resmanager.vbom);     sprite cloud2 = new sprite(300,600, resmanager.cloudtwotextureregion, resmanager.vbom);*/      scene.setbackground(autoparallaxbackground);

tried create autoparallaxbackground , set current scene object got black , hazy blinking screen after running code. please me out here. spend whole night after solving problem.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
