ios - How to replace layers? -

-

i started learn objective-c , use cocos2d 1 month ago.

i want replace 3 different layers tapping buttons. @ first, tried use "cclayermultiplex." then, use "if sentence." layers overlap or crash when buttons tapped. want previous layer disappear when new layer appears, old layer remains code now.

i think using "cclayermultiplex" best option, can't make work want to. below code. i'm afraid there're poor sentences...

@interface gslayout : cclayer { // button items ccmenuitemimage *file1; ccmenuitemimage *file1pushed; ...   // layer  (replace) cclayer *layer1; cclayer *layer2; cclayer *layer3;   // replace layers cclayermultiplex* mplayer;  }  @end     @implementation gslayout -(id) init{ if( (self=[super init])) {     cclog(@"%@: %@", nsstringfromselector(_cmd), self);      self.istouchenabled = yes;      // buttons      file1 = [ccmenuitemimage itemfromnormalimage:@"icon-small-50.png"                                                          selectedimage: @"icon-small.png"                                                                 target:nil                                                               selector:nil];     file1pushed = [ccmenuitemimage itemfromnormalimage:@"icon-small.png"                                                            selectedimage:@"icon-small-50.png"                                                                   target:nil                                                                 selector:nil];     ccmenuitemtoggle *togglefile1 = [ccmenuitemtoggle itemwithtarget:self                                                             selector:@selector(selectone:)                                                                items:file1,file1pushed, nil];     togglefile1.anchorpoint = cgpointmake(0.5f, 0.5f);              file2 = [[ccmenuitemimage itemfromnormalimage:@"icon-small-50.png"                                                     selectedimage: @"icon-small.png"                                                            target:nil                                                          selector:nil]retain];     file2pushed = [[ccmenuitemimage itemfromnormalimage:@"icon-small.png"                                                             selectedimage:@"icon-small-50.png"                                                                    target:nil                                                                 selector:nil]retain];     ccmenuitemtoggle *togglefile2 = [ccmenuitemtoggle itemwithtarget:self                                                             selector:@selector(selecttwo:)                                                                items:file2,file2pushed, nil];     togglefile2.anchorpoint = cgpointmake(0.5f, 0.5f);      ...      ccmenu *togglemenu = [ccmenu menuwithitems:togglefile1,togglefile2,togglefile3, nil];     [togglemenu alignitemshorizontally];     togglemenu.anchorpoint = cgpointmake(0, 1.0f);     cgsize screensize = [[ccdirector shareddirector] winsize];     togglemenu.position = cgpointmake(screensize.width/2, screensize.height);      [self addchild:togglemenu];             // create layers     layer1 = [gamefile1 node];     layer2 = [gamefile2 node];     layer3 = [gamefile3 node];     mplayer = [cclayermultiplex layerwithlayers:layer1,layer2,layer3, nil];          } return self; }  - (void) selectone: (ccmenuitem*) menuitem  { nslog(@"the first menu called");  if([layer1 isrunning])  {   nil;          nslog(@"the layer1 running");  } else if([layer2 isrunning]) {    [mplayer switchto:0];         nslog(@"the layer2  replaced");  }else if([layer3 isrunning]) {    [mplayer switchto:0];                 nslog(@"the layer3  replaced");  } else{    [self addchild:layer1];    nslog(@"the layer1 called");  }   }  - (void) selecttwo: (ccmenuitem*) menuitem  { nslog(@"the second menu called");  if([layer2 isrunning]) {   nil;             nslog(@"the layer2 running"); } else if([layer1 isrunning]) {   [mplayer switchto:1];   nslog(@"the layer1  replaced"); } else if([layer3 isrunning]) {   [mplayer switchto:1];   nslog(@"the layer3  replaced"); }else{   [self addchild:layer2];   nslog(@"the layer2 called"); }  }  - (void) selectthree: (ccmenuitem*) menuitem  { nslog(@"the third menu called");     ...  }

please give me advice! thank in advance!

i'll add codes.

@interface gamefile1 : cclayer { ccsprite* sprite; }  @implementation gamefile1 -(id) init{ if( (self=[super init])) {      cgsize screensize = [[ccdirector shareddirector] winsize];     ccmenuitemimage *sounditem1 = [ccmenuitemimage itemfromnormalimage:@"button1.png"                                                          selectedimage: @"icon.png"                                                                 target:self                                                               selector:@selector(dosomethingone:)];              ccmenuitemimage *sounditem2 = [ccmenuitemimage itemfromnormalimage:@"button2.png"                                                          selectedimage: @"icon.png"                                                                 target:self                                                               selector:@selector(dosomethingtwo:)];      ...         ccmenu * mymenu = [ccmenu menuwithitems:sounditem1, sounditem2,sounditem3,sounditem4, sounditem5,sounditem6,sounditem7, sounditem8,sounditem9,sounditem10,sounditem11,sounditem12, nil];       [mymenu alignitemsinrows:[nsnumber numberwithint:4],[nsnumber numberwithint:4],[nsnumber numberwithint:4] ,nil];        mymenu.position = cgpointmake(370, 120);       [self addchild:mymenu];       sprite = [ccsprite spritewithfile:@"o0400026611355530621.jpg"];     sprite.scale = 0.5f;         sprite.position = cgpointmake(screensize.width/2, screensize.height/2);     sprite.anchorpoint = cgpointmake(1.0f, 0);      [self addchild:sprite];  - (void) dosomethingone: (ccmenuitem  *) menuitem  { nslog(@"the first menu called");  [[simpleaudioengine sharedengine] playeffect:@"one.wav"];  [sprite settexture:[[cctexturecache sharedtexturecache] addimage: @"one.jpg"]];  }   - (void) dosomethingtwo: (ccmenuitem  *) menuitem  { nslog(@"the second menu called");  [[simpleaudioengine sharedengine] playeffect:@"two.wav"];  [sprite settexture:[[cctexturecache sharedtexturecache] addimage: @"one.jpg"]]; } ...  @end

since have loaded textures 3 layers, might have 3 sitting in separate cclayers 2 hidden @ given state using method similar to:

- (void) setlayer:(uint)show {     layerone.visible = (show == 0);     layertwo.visible = (show == 1);     layerthree.visible = (show == 2); }

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...

android - layout with fragment and framelayout replaced by another fragment and framelayout -

edit: so after comments below, revisted , realized hanging me up. imagine client list , client details activity started : public class clientsmainactivity extends fragmentactivity { @override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); //studiotabopenhelper db; setcontentview(r.layout.main_client_activity); } } so works great, starts main_client_activity (defined in layout below, , call activity when button on main screen clicked): intent intent = new intent(getactivity(), clientsmainactivity.class); startactivity(intent); easy issue is, clientsmainactivity not call oncreateview or anything, sets layout layout defines fragment, , listfragment. fine cause not trying pass clientsmainactivity , if have hypothetical activity like: sessionmainsactivity called when click on session edit of client, not calling sessionsmainactivity same way (starts activity sets alayout), want layout set defines...
