I'm new to Cocos2D and I'm now trying ABC123 (downloaded from internet, created by kwigbo)
I wonder why it works all fine by the simulator, but while i'm using my iPad to test it.... problem comes up.. I tried for 2weeks but still cannot solve it... hope anyone can teach me?? Thanks a lot....
Originally the bubble will appear AFTER player memorized the word's locations, but when using iPad to run it... the bubble appear soon after started, player cannot remember the word locations for playing the game at all...
I've tried to change the delay part from delayTime = 1.5 to 4;:
#GameLayer.m
float delayTime = 4.0;
if(dataManager.currentlevel > 10) delayTime = 2.5;
[self runAction:[Sequence actions:[DelayTime actionWithDuration:delayTime], [CallFunc actionWithTarget:self selector:#selector(showBubbles)], nil]];
It delay in simulator but didn't change in iPad....
Is there any relationship with OrbSprite.m?
#OrbSprite.m's init:
Label *l = [[Label alloc] initWithString:#"" dimensions:CGSizeMake(50, 50) alignment:UITextAlignmentCenter fontName:#"Arial Rounded MT Bold" fontSize:45];
self.label = l;
[l release];
//[self initWithFile:#"bubble1.png"];
Animation *bub = [Animation animationWithName:#"bubble" delay:1.0f images:#"bubble1.png", #"bubble2.png", nil];
self.bubble = bub;
[bub release];
[self addAnimation:bubble];
Or should I do anything on this line?
- (void) showBubble
{
isBubble = YES;
[self setDisplayFrame:#"bubble" index:1];
self.scale = .1;
[self runAction:[Sequence actions: [ScaleTo actionWithDuration:.1 scale:0.1], [ScaleTo actionWithDuration:.1 scale:1], nil]];
[self removeChild:label cleanup:YES];
}

I would like to know how to change the ZOrder of a CCSprite in a CCSequence. I have tried using CCCallBlock as suggested in another thread but it has bugged out and stops the other sprites of the same class moving. Is there another method someone can suggest?
crystalEntryPoint = [self position];
float xD = [crystal position].x - crystalEntryPoint.x;
float yD = [crystal position].y - crystalEntryPoint.y;
CGPoint dest = ccp(crystalEntryPoint.x + (xD * 2),crystalEntryPoint.y + (yD * 2));
float easingRate = 2;
CCMoveTo *moveTo = [CCMoveTo actionWithDuration:1 position:dest];
CCMoveTo *moveBack = [CCMoveTo actionWithDuration:1 position:crystalEntryPoint];
CCEaseInOut *easeTo = [CCEaseInOut actionWithAction:moveTo rate:easingRate];
CCEaseInOut *easeBack = [CCEaseInOut actionWithAction:moveBack rate:easingRate];
CCCallBlock *zOrderBehind = [CCCallBlock actionWithBlock:^{ [self setZOrder:kManaSpriteBehindCrystalZValue]; }];
CCCallBlock *zOrderInFront = [CCCallBlock actionWithBlock:^{ [self setZOrder:kManaSpriteZValue]; }];
CCSequence *seq = [CCSequence actions:easeTo,zOrderBehind,easeBack,zOrderInFront,nil]; //,zOrderInfront
CCRepeatForever *rep = [CCRepeatForever actionWithAction:seq];
[self runAction:rep];
Try CCCallBlockN which gives the block the node running the action as parameter. The current setup retains self inside the block which may cause the node not to dealloc later on because the sequence runs forever and thus holds a strong self-reference until the node deallocates - I can't say if cocos2d is able to clean it up properly, it should but it might not.
Not sure if this is related to your issue or not but it seems to me a likely explanation considering everything else in the code snippet looks fine.
CCCallBlockN *zOrderBehind = [CCCallBlockN actionWithBlock:^(CCNode* node){
[node setZOrder:kManaSpriteBehindCrystalZValue];
}];
CCCallBlockN *zOrderInFront = [CCCallBlockN actionWithBlock:^(CCNode* node){
[node setZOrder:kManaSpriteZValue];
}];
If that doesn't work either then try CCActionTween which allows changing any property by name.
id zOrderChange = [CCActionTween actionWithDuration:0.0
key:"zOrder"
from:kManaSpriteZValue
to:kManaSpriteZValue];
I'm not sure if from / to having the same value will work. If it doesn't try using 0 as the from parameter and perhaps even increasing duration to some low value like 0.01.
I'm currently doing the tutorial http://www.raywenderlich.com/25736/how-to-make-a-simple-iphone-game-with-cocos2d-2-x-tutorial .
I have a problem on the part that reacts to when a ninja star hits the monsters. My code is:
- (void)update:(ccTime)dt {
NSMutableArray *projectilesToDelete = [[NSMutableArray alloc] init];
for (CCSprite *projectile in _projectiles) {
NSMutableArray *monstersToDelete = [[NSMutableArray alloc] init];
for (CCSprite *monster in _monsters) {
if (CGRectIntersectsRect(projectile.boundingBox, monster.boundingBox)) {
[monstersToDelete addObject:monster];
}
}
for (CCSprite *monster in monstersToDelete) {
[_monsters removeObject:monster];
[self removeFromParentAndCleanup:YES];
}
if (monstersToDelete.count > 0) {
[projectilesToDelete addObject:projectile];
}
[monstersToDelete release];
}
for (CCSprite *projectile in projectilesToDelete) {
[_projectiles removeObject:projectile];
[self removeChild:projectile cleanup:YES];
}
[projectilesToDelete release];
}
which works okay, does not crash, but when I hit a monster with an projectile, the screen turns black on the simulator. No error or anything. I logged the CGRectIntersectRect, and it records as it is supposed to. The problem is that when this happens, it all turns black. Any idea why?
I looked at the tutorial, and the line i identified in the comments above reads :
[self removeChild:monster cleanup:YES];
Try that.
You're doing [self removeFromParentAndCleanup:YES] which removes your current layer from the parent. So you get a black screen.
You probably want to remove the child monster from the layer instead.
I've created a quiz game, that implements a time bar. In the first play it's all right, but if, after gameover, the player tap "restart", the game goes on properly, but the time bar disappears!
Here my code from GameOverLayer to Game:
-(void) restart {
[[CCDirector sharedDirector] replaceScene:[HelloWorldLayer node]];
}
Here the function to create a new question
-(void)creaDomanda{
//bar
CCProgressFromTo *to1 = [CCProgressFromTo actionWithDuration:MaxTime from:100 to:0];
bar = [CCProgressTimer progressWithFile:#"barra.png"];
bar.type = kCCProgressTimerTypeHorizontalBarLR;
[bar setPosition:ccp(size.width - 250 , size.height - 18)];
int randomValue = (arc4random() % 4) + 1;
NSString *stringa = [NSString stringWithFormat:#"Domanda%i", randomValue];
dictionary = [plistData objectForKey:stringa];
domanda = [dictionary valueForKey:#"Titolo"];
labelDomanda = [CCLabelTTF labelWithString:domanda fontName:#"Marker Felt" fontSize:24];
labelDomanda.position = ccp( size.width /2 , 400 );
[self addChild: labelDomanda];
int rispostaEsatta = [[dictionary valueForKey:#"Soluzione"] intValue];
menu = [CCMenu menuWithItems:nil];
for (int i = 1; i<5;i++)
{
if(rispostaEsatta == i){
item = [CCMenuItemFont itemFromString:[dictionary valueForKey:
[NSString stringWithFormat:#"Risposta%i",i] ]
target:self selector:#selector(corretto)];
}else{
item = [CCMenuItemFont itemFromString:[dictionary valueForKey:
[NSString stringWithFormat:#"Risposta%i",i] ]
target:self selector:#selector(sbagliato)];
}
[menu addChild:item];
}
//[..]
[self addChild:menu];
[self addChild:bar];
[bar runAction:to1];
}
And here one of the correct/wrong method (similar) that after all, create a new question:
-(void)sbagliato{
CCLOG(#"Sbagliato");
if (menu) [self removeChild:menu cleanup:YES];
if (labelDomanda) [self removeChild:labelDomanda cleanup:YES];
if (bar) [self removeChild:bar cleanup:YES];
labelRisultato = [CCLabelTTF labelWithString:#"Hai sbagliato!" fontName:#"Marker Felt" fontSize:24];
[labelRisultato setColor:ccc3(255, 1, 1)];
labelRisultato.position = ccp(size.width / 2, 280);
[self addChild:labelRisultato];
[self gameOver:2 punteggio:0];
// Richiamiamo il metodo per eliminare la label dopo 0,3 secondi
[self performSelector:#selector(eliminaLabel) withObject:nil afterDelay:0.5];
increment = increment - 20;
[pointLabel setString: [NSString stringWithFormat: #"Punti: %i", increment]];
// new question
[self performSelector:#selector(creaDomanda) withObject:nil afterDelay:0.5];
}
Can anyone explain to me please why when I restart the time bar desappers?
Thank You
My best guess:
The CCProgressFromTo action is still running. Since it progresses down to 0, the CCProgressTimer eventually doesn't display any part of it anymore. This may continue even if you run another CCProgressFromTo action on the progress timer.
Solution: be sure to stop any running CCProgressFromTo actions before running another.
If that doesn't fix it, then I imagine the CCProgressTimer needs to be reset by setting percentage back to 100.
I created a CCAnimation as seen below. I tried lowering the delay to something below .05f and the animation now fails to complete! Its only 8 frames. I don't know if I am doing something wrong. At first I thought it was a memory leak and I was losing the action, so I assigned it to a strong property to test that, and still did it. I'm not sure how the delay could cause my animation to fail to finish. I am running in the simulator at 60 frames per sec.
Using Kobold 2.0.4
Can anyone help?
else if([model currentState] == PROCESSING_FIRST_ACTION)
{
CCDirector* director = [CCDirector sharedDirector]; // process model
//Get the top left corner of the screen
int screen_height = director.screenSizeAsPoint.y;
int screen_width = director.screenSizeAsPoint.x;
id attacker = [model attacker];
id attackChoice = [attacker getRegisteredAttack];
CCAction* attack = [model.resourceManager animation: #"simple-attack-frame"];
CCSprite * attackSprite = [model.resourceManager sprite: #"simple-attack-frame-01"];
attackSprite.position = ccp(screen_width - rxa(80), screen_height - rya(80));
attackSprite.tag = 5;
self.action = attack;
CCNode * check = [self getChildByTag:5];
if(check == nil)
{
[self addChild: attackSprite];
[attackSprite runAction:attack];
}
}
resource manager:
-(id)animation: (NSString*)_resource
{
NSMutableArray *frames = [NSMutableArray array];
for(int i = 1; i <= 8; ++i)
{
[frames addObject:
[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:
[NSString stringWithFormat:#"%#-0%d", _resource, i]]];
}
CCAnimation *animation = [CCAnimation animationWithSpriteFrames: frames delay:1/60];
CCAction * action = [CCAnimate actionWithAnimation: animation];
return action;
}
In your line
CCAnimation *animation = [CCAnimation animationWithSpriteFrames: frames delay:1/60];
you're setting the delay to 1/60, but as 1 and 60 are both integers, 1/60 is 0. Try using 1.0f/60.0f and you'll get a floating point divide.
After digging around on the web I found a solution. I'm not the one who submitted this solution but I can attest that it fixed my problems:
https://github.com/cocos2d/cocos2d-iphone/commit/60f9cc98783b9a6a5635db4f468f83e0511c74c8
I am making a slot machine game in iphone. I am using cocos2d as its language. I am greatly disturb coding for the method that will animate score in the game. The animation looks like with the fps. Can you help me do it. Animating the score in cocos2d. Can you share sample code that looks like what i need now. Thanks in advance.
Here is how I do my score. it is not really animated, but if you want it to be like fps this will do it. Just call this method when your score changes.
in your init method:
// create and initialize the _scoreLabel
_scoreLabel = [CCLabel labelWithString:#" "
dimensions:CGSizeMake(labelSizes.width,labelSizes.height)
alignment:UITextAlignmentLeft
fontName:#"Helvetica"
fontSize:20.0];
_scoreLabel.color = ccc3(255,255,255);
_scoreLabel.position = ccp((labelSizes.width / 2), (winSize.height - (labelSizes.height / 2)));
[self addChild:_scoreLabel z:1];
This is the score update method:
-(void)updateScore {
[_scoreLabel setString:[NSString stringWithFormat:#"Score: %d / %d", _score, _scoreToWin]];
}
Then to update the score when the score changes call it like this:
// Then later to set the Score
[self updateScore];
I've done it in this way:
_odd = _odd + _stage*value;
[self schedule:#selector(pointAdder) interval:1.0/(3.0*_odd)];
and
- (void)pointAdder {
if (_odd==0) {
[self unschedule:#selector(pointAdder)];
return;
}
else {
int tmp = [_lblScore.string intValue];
[_lblScore setString:[NSString stringWithFormat:#"%i",tmp+1]];
_odd--;
}
}
