Cocos2d-X中Menu的综合运用
今天将曾经写的代码和项目集成到了一个菜单中,能够通过菜单切换到曾经做的项目
程序的project文件夹
主要代码分析:
LessonMenu.h中实现创建菜单,遍历菜单通过菜单切换到各个项目
#ifndef _LessonMenu_H_ #define _LessonMenu_H_ #include "cocos2d.h" USING_NS_CC; class LessonMenu : public CCLayer { public: bool init(); static CCScene* scene(); void EnterLasson(CCObject* sender); //处理触摸事件 bool ccTouchBegan(CCTouch*,CCEvent); void ccTouchMoved(CCTouch*, CCEvent*); CREATE_FUNC(LessonMenu); }; #endif
LessonMenu.cpp中实现详细的功能
#include "LessonMenu.h" #include"Label.h" #include"MenuItem.h" #include"TextFieldTTF.h" #include"AppMacros.h" #include"LabelAtlas.h" #include"SceneSecond.h" #include"TextFieldTTF1.h" #include"BMFont.h" #include"Layer.h" #include"Sprite.h" #include"Zorder.h" #include"Coord.h" #include"Sprite1.h" #include"TCCEditBox.h" #include"Menu.h" #include "MenuContinus.h" #include "T14SwitchControl.h" #include "T15Slider.h" CCScene* LessonMenu::scene() { CCScene* s = CCScene::create(); LessonMenu* layer = LessonMenu::create(); s->addChild(layer); return s; } //保存创建的cpp文件 static const char* lessons[] = { "BMFont.cpp", "Coord.cpp", "Label.cpp", "LabelAtlas.cpp", "Layer.cpp", "Menu.cpp", "MenuItem.cpp", "SceneSecond.cpp", "Sprite.cpp", "Sprite1.cpp", "TCCEditBox.cpp", "TextFieldTTF.cpp", "TextFieldTTF1.cpp", "Zorder.cpp", "MenuContinus.cpp", "T14SwitchControl.cpp", "T15Slider.cpp" }; bool LessonMenu::init() { CCLayer::create(); //创建菜单 CCMenu* menu = CCMenu::create(); addChild(menu); for(int i = 0; i < sizeof(lessons)/sizeof(*lessons); i++) { //创建菜单项 CCMenuItemFont* item = CCMenuItemFont::create(lessons[i]); menu->addChild(item); //设置处理函数 item->setTarget(this, menu_selector(LessonMenu::EnterLasson)); //设置菜单项的ID item->setTag(10000 + i); } //对齐菜单项 menu->alignItemsVertically(); //触摸菜单项 setTouchEnabled(true); setTouchMode(kCCTouchesOneByOne); return true; } void LessonMenu::EnterLasson(CCObject* sender) { //强制类型转换 CCMenuItem* item = dynamic_cast<CCMenuItem*>(sender); //得到菜单项的ID int tag = item->getTag() - 10000; //用于调用场景 CCScene* scene = NULL; switch(tag) { case 0: { scene = BMFont::scene(); } break; case 1: { scene = Coord::scene(); } break; case 2: { scene = Label::scene(); } break; case 3: { scene = LabelAtlas::scene(); } break; case 4: { scene = Layer::scene(); } break; case 5: { scene = Menu::scene(); } break; case 6: { scene = MenuItem::scene(); } break; case 7: { scene = SceneSecond::scene(); } break; case 8: { scene = Sprite::scene(); } break; case 9: { scene = Sprite1::scene(); } break; case 10: { scene = TCCEditBox::scene(); } break; case 11: { scene = TextFieldTTF::scene(); } break; case 12: { scene = TextFieldTTF1::scene(); } break; case 13: { scene = Zorder::scene(); } break; case 14: { scene = MenuContinus::scene(); } break; case 15: { scene = T14SwitchControl::scene(); } break; case 16: { scene = T15Slider::scene(); } break; } if(scene) { CCDirector::sharedDirector()->pushScene(scene); } } //处理触摸事件 bool LessonMenu::ccTouchBegan(CCTouch* touch,CCEvent) { return true; } //处理触摸事件 void LessonMenu::ccTouchMoved(CCTouch* touch, CCEvent*) { // 获得触摸移动的距 CCPoint ptDelta = touch->getDelta(); // 仅仅上下滑动的方法 setPositionY(getPositionY() + ptDelta.y); }
LayerBack.h实现创建一个仅仅有一个返回button的层,通过返回button实现场景切换
#ifndef _LayerBack_H_ #define _LayerBack_H_ #include "cocos2d.h" USING_NS_CC; class LayerBack : public CCLayer { public: bool init(); void back(CCObject*); }; #endif
LayerBack.cpp中是详细实现的代码
#include "LayerBack.h" bool LayerBack::init() { CCLayer::init(); //得到窗体的尺寸 CCSize winSize = CCDirector::sharedDirector()->getWinSize(); CCMenu* menu = CCMenu::create(); addChild(menu); CCMenuItem* backItem = CCMenuItemImage::create("CloseNormal.png", "CloseSelected.png", this, menu_selector(LayerBack::back)); menu->addChild(backItem); //设置菜单项的位置(将菜单项设置到右下角) backItem->setPosition(ccp(winSize.width / 2 - backItem->getContentSize().width / 2, backItem->getContentSize().height / 2 - winSize.height / 2)); return true; } void LayerBack::back(CCObject*) { //场景切换 CCDirector::sharedDirector()->popScene(); }
运行结果:
