问题 I am really frustrated that making my adhoc app install to my device. I have got this problem in this app. I used a team provision file (i.e. with "*" as identifier) to build all my apps for adhoc. it works fine for all other apps. just this app, when i install, it pops up a message "a signed resource has been added modified or deleted" and getting the following message in the organizer console log. installd[53] : 0x303000 handle_install: Install of "/var/mobile/Media/PublicStaging/mygame.ipa

问题 I have a CCLayer class called SuccessLayer. It gets added to the scene when the level is complete, like so: SuccessLayer *successLayer = [SuccessLayer node]; [self addChild:successLayer]; In SuccessLayer, I want to have a rock fly by, I'm trying to achieve that with this: -(void)onEnter{ Asteroid *asteroid = [Asteroid spriteWithFile:@"rocks.png"]; asteroid.position = ccp(0, 500); [self addChild:asteroid]; CCMoveTo *move = [CCMoveTo actionWithDuration:2.0 position:ccp(1000, 0)]; [asteroid

问题 Hi im trying to retrieve an object of a specific class from an NSMutableArray, and then add it to self: eg: - (void) init{ _Objects = [[NSMutableArray alloc]init]; Psychicing *psy = [[Psychicing alloc]init]; [psy startPsychic]; [_Objects addObject: psy]; [psy release]; } This creates an object of class Psychicing, then runs the [psy startPsychic] method to create the internals of the class object. Then I add the psy object to _Objects NSMutableArray. -(void)startPsychic{ id psychicParticle =

问题 I'm having a hell of a time with the CCMenu class. To create a menu with this class it forces you to call a method called initWithItems, which takes a va_list. I need to generate this list at runtime, and I read that creating a C array and passing that can function just as va_list does under the covers, only it is failing. I have an NSArray of items I want in the va_list, and these items are a SUBCLASS of CCMenuItem, the class that menuWithItems is expecting in the va_list. If you hardcode

问题 I already have a joystick programmed (finally) and I was wondering how I would get a 'hero' to move about the screen based on where the joystick is? I am using Cocos2d and any help would be greatly appreciated! 回答1: The simplest way to do this is to subclass CCNode for your player object and then manipulate it as you would any other CCNode . To start with, you can change the player's position struct like so: player.position = ccp( player.position.x + [joystick xValue], player.position.y +

问题 I am a bit confused on when to use CC_CONTENT_SCALE_FACTOR() in my app. I use Box2D for collision detection, and I make a b2Body of vertices. Now should I divide each point only by the PTM_Ratio or by the PTM_Ratio multiplied by CC_CONTENT_SCALE_FACTOR()? Should I be using CC_CONTENT_SCALE_FACTOR() anywhere in my app if I am not dealing with pixels? Should I only use CC_CONTENT_SCALE_FACTOR() for GLESDebugDraw like this? _debugDraw = new GLESDebugDraw( ptmRatio * CC_CONTENT_SCALE_FACTOR()); ?

问题 In Cocos2d 2.0 I used below code to use single image for normal and selected image with colour change on selection. CCSprite *twitter_1 = [CCSprite spriteWithSpriteFrameName:FRAME_MM_TWR_1]; CCSprite *twitter_2 = [CCSprite spriteWithSpriteFrameName:FRAME_MM_TWR_2]; twitter_2.color = ccc3(128,128,128); CCMenuItemSprite *twitterBtn = [CCMenuItemSprite itemWithNormalSprite:twitter_1 selectedSprite:twitter_2 target:self selector:@selector(twitterBtnPress:) ]; In Cocos2d v3, I can use CCButton as

问题 I almost have read everything about Anchor Point and scaling. I still have no idea what is going on with a sprites position when i scale it. The scenario is this: When i tap on screen, sprite's width will decrease about %50 and height will increase about same scale. Then it will get back to its normal scale. id scaleUpAction = [CCEaseInOut actionWithAction:[CCScaleTo actionWithDuration:.35 scaleX:0.5 scaleY:1.5] rate:1.0]; id scaleDownAction = [CCEaseInOut actionWithAction:[CCScaleTo
