问题 used cocos2d-x(version:"cocos2d-2.1beta3-x-2.1.1") under xcode I set CCEGLView::sharedOpenGLView()->setDesignResolutionSize(960, 640, kResolutionShowAll) to make my game fit different devices. With Everyplay effect on, my screen size will change auto, only happened when test on real machine, but no such bug when I use kResolutionExactFit. However, I need to use kResolutionShowAll. With iphone4 it works all well,but with ipad and iphone 5(I think all devices except screen size is 960*640) have

问题 I'm having some issues. I have a cocos2d game I'm just about done developing. However I've run into a problem where I need to enable portrait orientation in my apps plist for game center sign in to work without throwing a SIGABRT error. So once I enable that from my app's build summary page (Or add it to the info.plist file as a supported orientation) it works fine. But then anytime in my game if you turn the iPhone it will flip to portrait mode if it senses you turned it that way. I've tried

问题 Where do you need to add your images in your Cocos2dx Android project (in Eclipse)? They're currently in the 'Resources' folder like what is mentioned on Ray Wenderlich's blog, but I get an error when I run it in the emulator: "get data from (assets/myFileName) failed" for each image. I also added these images to the assets folder in Eclipse, and it makes no difference. It works fine on the iOS side. Any suggestions? 回答1: I believe you need to run ./build_native.sh in your android folder

问题 I need to create joint between two bodies in layer. Joints are to be added in physics world. How can i access physics world in layer? 回答1: My JavaScript implementation. Hope it will help. var space; function initPhysics() { space = new cp.Space(); space.gravity = cp.v(0, -800); space.iterations = 30; space.sleepTimeThreshold = Infinity; space.collisionSlop = Infinity; } function addJoints() { chainTableJoint1 = new cp.PivotJoint(chainEnd1, tableBackBody, cp.v.add(cp.v(chainEnd1.getPos().x,

问题 has anyone an idea how to convert a UIImage to cocos2d-x CCSprite. My latest attempt was was: 1. Store the UIImage as png on the phone 2. Load the png as a CCSprite [UIImagePNGRepresentation(photo) writeToFile:imagePath atomically:true]; CCSprite *sprite = CCSprite::spriteWithFile(imagePath); But this crashed in CCObject retain function void CCObject::retain(void) { CCAssert(m_uReference > 0, "reference count should greater than 0"); ++m_uReference; } And I do not understand how Walzer Wangs

问题 I added class GraphicsScene.h: #pragma once #include "cocos2d.h" class GraphicsScene : public cocos2d::Layer { public: static cocos2d::Scene* createScene(); virtual bool init(); CREATE_FUNC(GraphicsScene); }; Then #include "GraphicsScene.h" USING_NS_CC; Scene* GraphicsScene::createScene() { auto scene = Scene::create(); auto layer = GraphicsScene::create(); scene->addChild(layer); return scene; } bool GraphicsScene::init() { if ( !Layer::init() ) { return false; } auto sprite = Sprite::create

问题 UPDATE i changed to more simpler example Ok , now i really puzzled i simplified the class as as i was reading on the net the suggestion was to extend CCNode better then CCSprite and keep it as member of the CCNode so here is the very simpleminded example based on the Hello cpp. the problem remine the same , when touching any of the Gem instances i get printed the last Gem added , why ?? i expect that each Touchwill give me the correct instance that have bean touched ( i print id and name ) Im
