copied!<p>I'm having trouble with something that I think is very simple, but i just cant figure it out.</p> <p>I have a scene named WavePrototypeScene</p> <p>WavePrototypeScene.h</p> <pre><code>#ifndef __WAVE_PROTOTYPE_SCENE_H__ #define __WAVE_PROTOTYPE_SCENE_H__ #include "cocos2d.h" #include "WavePrototypeGameLayer.h" #include "WavePrototypeInterfaceLayer.h" using namespace cocos2d; class WavePrototypeScene : public CCScene { public: virtual bool init(); static cocos2d::CCScene* scene(); CREATE_FUNC(WavePrototypeScene); }; #endif </code></pre> <p>WavePrototypeScene.cpp</p> <pre><code>#include "WavePrototypeScene.h" CCScene* WavePrototypeScene::scene() { CCScene * scene = NULL; do { scene = CCScene::create(); CC_BREAK_IF(! scene); // add game layer WavePrototypeGameLayer *layer1 = WavePrototypeGameLayer::create(); CC_BREAK_IF(! layer1); scene->addChild(layer1, 1, 1); // add interface layer WavePrototypeInterfaceLayer *layer2 = WavePrototypeInterfaceLayer::create(); CC_BREAK_IF(! layer2); scene->addChild(layer2, 2, 2); } while (0); return scene; } </code></pre> <p>then I have my two layers WavePrototypeGameLayer and WavePrototypeInterfaceLayer</p> <p>WavePrototypeGameLayer.h</p> <pre><code>#ifndef __WAVE_PROTOTYPE_GAME_LAYER_H__ #define __WAVE_PROTOTYPE_GAME_LAYER_H__ #include "cocos2d.h" #include "WavePrototypeInterfaceLayer.h" using namespace cocos2d; class WavePrototypeGameLayer : public CCLayer { public: virtual bool init(); static CCScene* scene(); CREATE_FUNC(WavePrototypeGameLayer); }; #endif </code></pre> <p>WavePrototypeGameLayer.cpp</p> <pre><code>#include "WavePrototypeGameLayer.h" bool WavePrototypeGameLayer::init() { bool bRet = false; do { int health = 10; bRet = true; } while (0); return bRet; } </code></pre> <p>WavePrototypeInterfaceLayer.h</p> <pre><code>#ifndef __WAVE_PROTOTYPE_INTERFACE_LAYER_H__ #define __WAVE_PROTOTYPE_INTERFACE_LAYER_H__ #include "cocos2d.h" #include "WavePrototypeGameLayer.h" using namespace cocos2d; class WavePrototypeInterfaceLayer : public CCLayer { public: virtual bool init(); static CCScene* scene(); CREATE_FUNC(WavePrototypeInterfaceLayer); void menuAction(CCObject* pSender); }; #endif </code></pre> <p>WavePrototypeInterfaceLayer.cpp</p> <pre><code>#include "WavePrototypeInterfaceLayer.h" bool WavePrototypeInterfaceLayer::init() { bool bRet = false; do { CCMenuItemImage *actonButtonItem = CCMenuItemImage::create("actionbutton.png", "actionbuttonpressed.png", this, menu_selector(WavePrototypeInterfaceLayer::menuAction)); actonButtonItem->setPosition(ccp(55, 55)); CCMenu* actionButtonMenu = CCMenu::create(actonButtonItem, NULL); actionButtonMenu->setPosition(CCPointZero); this->addChild(actionButtonMenu, 10); char text[256]; sprintf(text, "Health: 0"); healthLabel = CCLabelTTF::create(text, "Arial", 24); healthLabel->setPosition(ccp(100, 100)); this->addChild(healthLabel, 10); bRet = true; } while (0); return bRet; } void WavePrototypeInterfaceLayer::menuAction(CCObject* pSender) { //button hit } </code></pre> <p>my code has a lot more than this, I just cut out everything else for simplicity.</p> <p>basically what I want is that when I hit the button on the interface layer, it pulls the int value from the gamelayer instance with the tag 1, and loads it into the label in the interface layer.</p> <p>I have tried many things to get this to work and I just cant seem to get it to work correctly.</p> <p>in cocos2d in objective-C see you can do this by doing WavePrototypegameLayer* interface = (WavePrototypegameLayer*)[self.parent getChildByTag:1];</p> <p>is there an equivalent to that in cocos2d-x</p>
