This allows you to select a boxed region of the spritesheet to be displayed. CCSpriteBatchNode

问题 I have a CCSprite called sprite that is a child of a CCLayer called movingLayer that is itself a child of the current CCLayer running my game logic, so it is self in this case. movingLayer is moving back and forth across the screen in a repeat forever action and sprite is riding along on it. I want to get sprite to "get off" of movingLayer and "get on" to self where it can do some actions of its own. When I try to do this, I need to tell movingLayer to remove sprite and self to add sprite.

问题 Hi there I'm having problems as stated with CCScrollLayer in the lateste cocos2d beta, mainly that on compiling I get: use of undeclared identifier 'CC_GL_BLEND' . Is there any way to sort this problem that anyone has found yet? 回答1: Safely you can comment that line..anyway blending is already enabled...and everything works fine after this change in cocos2D 2.1 beta. // Set GL Values #if COCOS2D_VERSION >= 0x00020000 // ccGLEnable(CC_GL_BLEND); //Guru ccPointSize( 6.0 * CC_CONTENT_SCALE

问题 I am writing because I have a serious problem - I have bought the Commander Cool game on the cartoonsmart site. However, a serious problem occured. The application cannot be accepted by the iTune Connect validation. I tried to publish it from two different developer accounts and the error still occurs. The error suggests some problems with the certificate but I am sure it is 100% right because I have published more than 20 apps in the App Store as for now. I ask you for help because you are

问题 Currently using cocos2d. I have a plist data name myplist.plist. Inside the plist are all integers.. How do i read the data and the int in it? 回答1: NSString *path = [[NSBundle mainBundle] bundlePath]; NSString *dictionaryPath = [path stringbyAppendingPathComponent:@"myplist.plist"]; NSDictionary *integerDictionary = [[NSDictionary alloc] initWithContentsOfFile:dictionaryPath]; int myInteger1 = [[integerDictionary objectForKey:@"integer1"] intValue]; int myInteger2 = [[integerDictionary

问题 How can I accomplish this? A programmatic solution (Objective-c) is great, but even a non-progarmmatic one is good. I have pixelmator -> But that doesn't give you the option. I can't seem to do it with Preview either. I have tried googling, but haven't been able to find a solution so far. The only tool I have been able to use to do this is TexturePacker, but that creates a sprite sheet. 回答1: You can use libpng to convert the PNG image to three-byte (8:8:8) RGB. Then you can downsample to the

问题 I am developing an iPad game that uses cocos2d and requires a virtual joystick. I have a prototype up and running using SneakyJoystick. However, I realized that my game design requires me to use CCTransitions to move the user between different instances of CCScene in order to get the visual effect I want. The problem is, I don't want the user controls (like the joystick) to be affected by the CCTransitions- I want them to remain on the screen (in a different part of the screen than the part

问题 Is it possible in Cocos2d to create a move animation that would go on a specific path? For example, how should I do if I need an object to move on an arc or full circle? Regards! 回答1: Sure you can do this using : ccBezierConfig bezier; bezier.controlPoint_1 = ccp(320,0); // control point 1 bezier.controlPoint_2 =ccp(0,0); // control point 2 bezier.endPosition = ccp(endPoint.x,endPoint.y) ; id bezierForward = [CCBezierTo actionWithDuration:3 bezier:bezier]; [ball runAction:bezierForward]; you

问题 I've just gotten basic UIKit down. I've made several personal apps and such, but now I'm ready to move on to a game with some other developers. Both of these frameworks look powerful and have tons of bells and whistles. Does anyone have a preference? Are there pros and cons when compared to each other? They both seem to have similar syntax and performance. 回答1: while working as a game developer specifically for ios, cocos2d is best suitable.Some of the reason are as: 1.Open source and
