问题 I have a button in Spritebuilder. Characteristics are as follows: Doc root var: _playbutton | Selector: play Target: | Document root Code for the button in Xcode: CCButton *_playButton; - (void)play { CCScene *scene = [CCBReader loadAsScene:@"LevelSelect"]; [[CCDirector sharedDirector] replaceScene:scene]; } LevelSelect is a seperate scene in Spritebuilder. This code worked until I had problems with my Back button, which inhabits scene LevelSelect. To see characteristics, see my "Using

问题 I have an existing game that I want to have a title screen with a button "play" to the app that loads the game. EDIT: The interface was made in Level Helper 回答1: Here's how you can implement a menu that changes scenes with a transition. In your HelloWorldLayer.m file, add this: -(id) init { if( (self=[super init])) { CCMenuItemImage *menuImage = [CCMenuItemImage itemFromNormalImage:@"yourimage.png" selectedImage:@"Icon.png" target:self selector:@selector(changeScene:)]; CCMenu *menu; menu =

问题 I'm using the UIPinchRecognizer and an open pinch to detect when someone 'pulls apart' a sprite in a Box2D world. If I use UIPinchGestureRecognizer to detect pull aparts, it breaks my mouse joints when two objects are dragged together - which is less than ideal. I've tried to split my problem into two questions - how to detect an open pinch without UIPinchGestureRecognizer and is it is possible to suppress the close pinch. How can I write my own class to detect an open pinch? That is, two

问题 I have an interesting problem handling touch events in a cocos2D program I’m writing. I have 3 CCLayer sublassed layers in a CCScene: backgroundLayer – z:0 – simple static layer used to display a background image. planetLayer - z:3 – display layer – visualization of data changes are displayed here. gameControlsLayer – z:5 – layer used to display data controllers such as sliders and buttons. I separated the planet and control layers because I want to pan and zoom the planet layer without

问题 I made an original post here At first, I tried to fill up a CGPoint **allPaths. With the first dimension being "a path" and the second dimension being "the waypoint". And I get a CGPoint out of this. For example : allPaths[0][2] would give me the CGPoint of the first path, third waypoint. I successfully did it in plain C with nasty loops. And now I am trying to do the same thing in Obj-C with NSMutableArrays. Here is my code : CCTMXObjectGroup *path; NSMutableDictionary *waypoint; int

Any one can please help me on this !!! 回答1: Here you can

问题 I have a set of sprite lists.i want to remove the topmost lying sprite if the sprites overlap. if ( popRect1.containsPoint( popRect1, location ) ) { BaloonList1.remove( baloons ); baloons.removeSelf(); } if ( popRect2.containsPoint( popRect2, location ) ) { BaloonList2.remove( baloons ); baloons.removeSelf(); } When two sprites of same list overlap and if i touch them only the topmost sprite will be removed...if 2 sprites are from different list and when i touch the topmost sprite both of

问题 I would like to appologize in advance however I think this question is overlooked. I have a project I have been working on and I would like to incorporate coco2d. How can I implement the coco2d-iphone-2.0 download. All the tutorials I have tried have either been outdated or left me with errors. I keep getting ARC Semantic Issue and ARC Restriction once I follow steps of other tutorials to add coco2d to an existing project. Thus, could someone be so kind as to put a step but step approach to

问题 I am trying to develop a car game in which opponents are coming from opposite direction. And we have to avoid collision. For this I want to move my background as the opponent cars approach the good car. What should I do to move the background? Regards, Stone 回答1: 1.- You need to create a map: example with program "Tiled". 2.- Add to resources 3.- Insert code: CCTMXTiledMap * tmxMap = [CCTMXTiledMap tiledMapWithGMXFile:@"Map.tmx"]; [tmxMap runAction:[CCMoveBy actionWithDuration:1.0 position
