I am having a problem when trying to push a button and going to the next scene. I get the SIGABRT error. I don't know what the problem is:
[...]
//Play Button
CCMenuItem *playbutton;
playbutton = [CCMenuItemFont itemWithString:#"Play" target:self selector:#selector(playButtonMeathod:)];
CMenu *menu = [CCMenu menuWithItems:itemAchievement,playbutton,itemLeaderboard, nil];
[menu alignItemsHorizontallyWithPadding:20];
[menu setPosition:ccp( size.width/2, size.height/2 - 50)];
// Add the menu to the layer
[self addChild:menu];
-(void)playButtonMeathod{
// Create a scene transition that uses the "RotoZoom" effect
CCTransitionRotoZoom *transition = [CCTransitionRotoZoom transitionWithDuration:1.0 scene:[Level_1 scene]];
// Tell the director to run the transition
[[CCDirector sharedDirector] replaceScene:transition];
[...]
One issue might be that the method signature is incorrect in your CCMenuItemFont selector target. Try:
CCMenuItemFont *playbutton = [CCMenuItemFont itemWithString:#"Play" target:self selector:#selector(playButtonMeathod)];

I am working on project with cocos2d-android.
What I need this time is : A CCSprite comes on the screen and stay 3-4 sec and remove automatically. What class is available to do this work
If anybody have done this thing earlier. Suggest me the way ?
I'll give you code example in Objective-c cause i've never dealt with cocos2d-android, i believe it's pretty straightforward
CCSprite *spriteToDisplayAndRemove = [CCSprite spriteWithFile:#"filename.png"];
[self addChild:spriteToDisplayAndRemove];//say CCLayer adds our sprite
CCDelayTime *delay = [CCDelayTime actionWithDuration:3];
CCCallBlock *block = [CCCallBlock actionWithBlock:^{
[self removeChild:spriteToDisplayAndRemove];
}];
[self runAction:[CCSequence actions:delay, block, nil]];
EDIT:
Since blocks are unavailable in cocos2d-android you might use CCCallFunc instead. Again, Objective-c sample:
CCSprite *spriteToDisplayAndRemove = [CCSprite spriteWithFile:#"filename.png"];
spriteToDisplayAndRemove.tag = 100;
[self addChild:spriteToDisplayAndRemove];//say CCLayer adds our sprite
CCDelayTime *delay = [CCDelayTime actionWithDuration:3];
CCCallFunc *callFunc = [CCCallFunc actionWithTarget:self selector:#selector(removeSprite)];
[self runAction:[CCSequence actions:delay, callFunc, nil]];
And here is your removeSprite method:
-(void)removeSprite
{
CCSprite *sprite = [self getChildByTag:100];
[self removeChild:sprite];
}
I enabled ARC for my cocos2d project.
Now i try doing the following:
BuildTowerMenu *menu = [BuildTowerMenu menuAtLocation:tileScreenPos];
[self addChild:menu];
And in the BuildTowerMenu class:
+(id)menuAtLocation:(CGPoint)location {
return [[self alloc] initMenuAt:location];
}
-(id) initMenuAt:(CGPoint)location {
if (self = [super init]) {
self.position = location;
CCSprite *item1 = [CCSprite spriteWithFile:#"Icon.png"];
item1.position = location;
[self addChild:item1];
}
return self;
}
But for some reason, the Sprite never shows up. After a bit of debugging i see that when i return from menuAtLocation, the CCSprite is still in the Array of children of BuildTowerMenu, but empty (only got an id).
If i actually add the sprite from outside it works and the Sprite is displayed:
BuildTowerMenu *menu = [BuildTowerMenu menuAtLocation:tileScreenPos];
CCSprite *item1 = [CCSprite spriteWithFile:#"Icon.png"];
item1.position = location;
[menu addChild:item1];
[self addChild:menu];
Any hints on what i did wrong here?
P.S.: i added a breakpoint in the dealloc of CCSprite, which never gets called (i guess it should be called if ARC is releasing it)...
I think that the problem is that you set equal positions to your menu and sprite.
I mean that this part of code
CGPoint location = ccp(200.f, 200.f);
[menu setPosition: location];
[sprite setPosition: location];
[menu addChild: sprite];
will add your sprite with position position (400.f, 400.f), relatieve to the menu's parent. You are doing almost the same thing in your BuildTowerMenu's initMenuAt: method/
As already commented on the initial question_:
Ok, it had nothing to do with ARC; the Sprite which seemed to be released was there, it was just a debugger - bug which didnt display it correctly. The problem was actually the line self.position = location; After moving the setposition after the addChild, everything worked.
I am coding a modal layer in cocos2d and I would like to use the OpenGL glScissor API call to crop the inside of a CCScrollLayer that I am using,
Basically,
Present some kind of Modal sprite
Put CCScrollLayer with assets on the modal sprite
I want to crop the CCScrollLayer so that it does not overflow the sprite.
Seems pretty simple.
The problem I'm having is that the visit function never seems to be get hit and thus glScissor never gets implemented.
I'm not sure what I'm doing wrong.
The way I do modals is I use blocks to handle a Yes and No condition/state.
// This appears in my "Pick City scene"
-(id) init
{
if ((self = [super init]))
{
NSLog(#"City list");
for (City *cityObj in listOfCities)
{
citySpriteOff = [CCSprite spriteWithSpriteFrameName:#"city.png"];
citySpriteOn = [CCSprite spriteWithSpriteFrameName:#"city_on.png"];
int x = [cityObj.x intValue];
int y = [cityObj.y intValue];
CCMenuItemSprite *mapMenuItem = [CCMenuItemSprite itemFromNormalSprite:citySpriteOff selectedSprite:citySpriteOn target:self selector:#selector(btnCity:)];
[mapMenuItem setTag:i];
[mapMenuItem setIsRelativeAnchorPoint:YES];
[mapMenuItem setAnchorPoint:CGPointMake(0, 0)];
[mapMenuItem setPosition:CGPointMake(x, y)];
[mapMenuItem setIsEnabled:YES];
[mapMenu addChild:mapMenuItem];
i++;
} // next
[self addChild:mapMenu z:2];
}
}
-(void) btnCity:(id)sender
{
NSLog(#"clicked a city button");
int tag = [sender tag];
City *cityObj = [listOfCities objectAtIndex:tag];
NSLog(#"You clicked on city: %#", cityObj.name);
[self lockLayers];
CCLayer *layer = [CCLayer node];
[self addChild:layer z:100];
[MapModalLayer ConfirmCity:cityObj onLayer:layer yesBlock:^{[self btnConfirmedCity:cityObj];} noBlock:^{[self unlockLayers];}];
}
-(void) btnConfirmedCity:(City *)cityObj
{
NSLog(#"confirmed city: %#", cityObj.name);
}
#pragma mark - Lock/Unlock layers
-(void) lockLayers
{
[self MenuStatus:NO Node:self];
}
-(void) unlockLayers
{
[self MenuStatus:YES Node:self];
}
// Disabled/Enable layers
-(void) MenuStatus:(BOOL)_enable Node:(id)_node
{
for (id result in ((CCNode *)_node).children) {
if ([result isKindOfClass:[CCMenu class]]) {
for (id result1 in ((CCMenu *)result).children) {
if ([result1 isKindOfClass:[CCMenuItem class]]) {
((CCMenuItem *)result1).isEnabled = _enable;
}
}
}
else
[self MenuStatus:_enable Node:result];
} // next
}
The actual modal code appears here,
#implementation MapModalLayer
- (id)init {
self = [super init];
if (self) {
// This method never seems to be called
NSLog(#"MapModalLayer init");
}
return self;
}
// This method never seems to be called
- (void) visit {
NSLog(#"Visit");
if (!self.visible)
return;
glPushMatrix();
glEnable(GL_SCISSOR_TEST);
glScissor(50, 50, 100 , 150);
[super visit];
glDisable(GL_SCISSOR_TEST);
glPopMatrix();
}
+ (void) CloseAlert: (CCSprite*) alertDialog onCoverLayer: (CCLayer*) coverLayer executingBlock: (void(^)())block {
// shrink dialog box
[alertDialog runAction:[CCScaleTo actionWithDuration:kAnimationTime scale:0]];
// in parallel, fadeout and remove cover layer and execute block
// (note: you can't use CCFadeOut since we don't start at opacity 1!)
[coverLayer runAction:[CCSequence actions:
[CCFadeTo actionWithDuration:0.2f opacity:0],
[CCCallBlock actionWithBlock:^{
[coverLayer removeFromParentAndCleanup:YES];
if (block) block();
}],
nil]];
}
+(void) ConfirmCity:(City *)cityObj onLayer:(CCLayer *)layer yesBlock :(void (^)())yesBlock noBlock:(void (^)())noBlock
{
CCLayerColor *coverLayer = [CoverLayer new];
[layer addChild:coverLayer z:INT_MAX]; // put to the very top to block application touches
[coverLayer runAction:[CCFadeTo actionWithDuration:kAnimationTime opacity:80]]; // smooth fade-in to dim with semi-transparency
CGSize winSize = [[CCDirector sharedDirector] winSize];
CCSprite *dialog = [CCSprite spriteWithSpriteFrameName:#"modal.png"];
[dialog setPosition:CGPointMake(winSize.width/2,winSize.height/2)];
[dialog setTag:kDialogTag];
//
// We put our CCScrollLayer *scroller content here... it doesn't matter what it is right now
//
//
// Finally we put our accept/reject buttons
//
// Tick/Cross buttons
CCSprite *closeButtonOn = [CCSprite spriteWithSpriteFrameName:#"btn_close.png"];
CCSprite *tickButtonOn = [CCSprite spriteWithSpriteFrameName:#"btn_accept.png"];
// add one or two buttons, as needed
CCMenuItemSprite *opt1Button = [CCMenuItemSprite itemFromNormalSprite:closeButtonOn
selectedSprite:nil
block:^(id sender){
// close alert and call opt1block when first button is pressed
[self CloseAlert:dialog onCoverLayer: coverLayer executingBlock:noBlock];
} ];
[opt1Button setPosition:CGPointMake(-200, -120)];
// create second button, if requested
CCMenuItemSprite *opt2Button = [CCMenuItemSprite itemFromNormalSprite:tickButtonOn
selectedSprite:nil
block:^(id sender){
// close alert and call opt2block when second button is pressed
[self CloseAlert:dialog onCoverLayer: coverLayer executingBlock:yesBlock];
} ];
[opt2Button setPosition:CGPointMake(40, -120)];
CCMenu *menu = [CCMenu menuWithItems:opt1Button, opt2Button, nil];
[menu setContentSize:dialog.contentSize];
[dialog addChild:menu z:2];
[coverLayer addChild:dialog];
}
#end
I think its because I only ever use MapModalLayer's private methods only.
But I am not sure.
Is there a way to allow me to use the glScissor in a modal like explained above?
I've tried moving the glScissor code to the display of the modal, but it never seems to do anything.
To confirm it is working, I moved the glScissor code to the parent and it seems to work fine.
Thus, how do I make the modal layer use/work with glScissor?
I have since resolved this problem.
I used the Viewport from http://pastebin.com/tWsEbxvJ
The way I did it was:
CoverLayer *coverLayer = [CoverLayer new];
[layer addChild:coverLayer z:INT_MAX]; // put to the very top to block application touches
[coverLayer runAction:[CCFadeTo actionWithDuration:kAnimationTime opacity:80]]; // smooth fade-in to dim with semi-transparency
// ------------------------------
CGSize winSize = [[CCDirector sharedDirector] winSize];
CCSprite *dialog = [CCSprite spriteWithSpriteFrameName:#"modal.png"];
[dialog setPosition:CGPointMake(winSize.width/2,winSize.height/2)];
[dialog setTag:kDialogTag];
.. // Build your pagesArray here for ScrollLayer...
// Now create the scroller and pass-in the pages (set widthOffset to 0 for fullscreen pages)
CCScrollLayer *scroller = [[CCScrollLayer alloc] initWithLayers:pagesArray widthOffset: 350];
[scroller setShowPagesIndicator:NO];
// finally add the scroller to your scene
//[dialog addChild:scroller];
Viewport *cn = [[Viewport alloc] initWithRect:CGRectMake(3, 0, dialog.contentSize.width-12, dialog.contentSize.height-5)];
[cn addChild:scroller];
[scroller release];
[coverLayer addChild:dialog z:1];
This allows me to put a modal on a layer, put a CCScrollLayer and make sure that the contents do not spill over the internals of the modal sprite I have made (this is why the width configuration looks a bit odd).
Thanks.
The title is pretty self explanatory. I am currently trying to make a cocos2d menu and it compiles flawlessly however it crashes right before fully launching and my log reads this...
+[NSInvocation invocationWithMethodSignature:]: method signature argument cannot be nil'
I don't know what this means here is my code though
// Standard method to create a button
CCMenuItem *Earth = [CCMenuItemImage itemFromNormalImage:#"1.png"
selectedImage:#"1.png"
target:self
selector:#selector(loadLevel:)];
Earth.position = ccp(160, 0);
CCMenuItem *Mars = [CCMenuItemImage itemFromNormalImage:#"2.png"
selectedImage:#"2.png"
target:self
selector:#selector(loadLevel:)];
Mars.position = ccp(160, 240);
CCMenuItem *Moon = [CCMenuItemImage itemFromNormalImage:#"3.png"
selectedImage:#"3.png"
target:self
selector:#selector(loadLevel:)];
Moon.position = ccp(160, 480);
CCMenu *myMenu = [CCMenu menuWithItems:Earth, Mars,Moon, nil];
[myMenu setPosition:ccp(160,240)];
[self addChild:myMenu z:0];
After adding this my program began to crash. Thanks for any help guys you are the best.
you need to implement loadLevel like this
-(void) loadLevel:(NSObject*) sender
{
}
please look the following picture
i want to do this function,when i click some button,it pop out a layer
my code is
-(id)init{
if (self = [super init]) {
CCMenuItem *successbtn = [CCMenuItemImage itemFromNormalImage:#"success.png"
selectedImage:#"success.png"
target:self
selector:#selector(successgame:)];
CCMenu *ccMenu = [CCMenu menuWithItems:successbtn, nil];
ccMenu.position=ccp(950,700);
[self addChild:ccMenu z:1 tag:2];
}
return self;
}
-(void)successgame:(id)sender{
//how can i write here?
}
so how can i write?
There is two possibilities. Either just add the button when you really want to show it and remove it from the Scenegraph as soon as it is not needed anymore.
Alternatively just make it invisible with the visible-property.
