项目移植手记

概述1.CCNotificationCenter废弃了,建议用EventListnerCustom layer._listener1 = cc.EventListenerCustom:create("component game over", onEvent) local eventDispatcher = cc.Director:getInstance():getEventDispatche

1.CCNotificationCenter废弃了,建议用EventListnerCustom

layer._Listener1 = cc.EventListenerCustom:create("component game over",onEvent)    local eventdispatcher = cc.Director:getInstance():getEventdispatcher()    eventdispatcher:addEventListenerWithFixedPriority(layer._Listener1,1)

2.UILabel ------->　Text

3. Node节点监听

local function onNodeEvent(event)        if "exit" == event then            ccexp.AudioEngine:stopAll()        end    end    layer:registerScriptHandler(onNodeEvent)

4. 声效

ccexp.AudioEngine:stopAll()

5 Layercolor

local bgLayer = cc.Layercolor:create(cc.c4b(0,128,255,255));

6 ccui.TextFIEld

local function textFIEldEvent(sender,eventType)                if eventType == ccui.TextfiledEventType.attach_with_ime then                    local textFIEld = sender                    textFIEld:runAction(cc.MoveBy:create(0.225,cc.p(0,20)))                    self._displayValueLabel:setString("attach with IME")                elseif eventType == ccui.TextfiledEventType.detach_with_ime then                    local textFIEld = sender                    textFIEld:runAction(cc.MoveBy:create(0.175,-20)))                    self._displayValueLabel:setString("detach with IME")                elseif eventType == ccui.TextfiledEventType.insert_text then                    self._displayValueLabel:setString("insert words")                elseif eventType == ccui.TextfiledEventType.delete_backward then                    self._displayValueLabel:setString("delete word")                end            end            local textFIEld = ccui.TextFIEld:create()            textFIEld:settouchEnabled(true)            textFIEld:setFontname(Font_Textname)            textFIEld:setFontSize(30)            textFIEld:setPlaceHolder("input words here")            textFIEld:setposition(cc.p(WidgetSize.wIDth / 2.0,WidgetSize.height / 2.0))            textFIEld:addEventListener(textFIEldEvent)            self._uiLayer:addChild(textFIEld)

7 .PageVIEw getPages():count() -----------> table.getn(cc.PageVIEw:getItems())

8 注册监听返回键

local function touch_key_back(keycode,event)        if keyCode == cc.KeyCode.KEY_BACK then        end    end    local Listener = cc.EventListenerKeyboard:create()    Listener:registerScriptHandler(touch_key_back,cc.Handler.EVENT_KEYBOARD_RELEASED )    local eventdispatcher = clayer:getEventdispatcher()    eventdispatcher:addEventListenerWithSceneGraPHPriority(Listener,clayer)

9自定义消息EventCustom

-- 发送消息 post message-- event将会被传递给消息接收函数，所以所有需要传递的数据都可放到event中local event = cc.EventCustom:new("MSG_TEST")event._usedata = {["state"]=self.curState,["actionID"]=self.actionID}cc.Director:getInstance():getEventdispatcher():dispatchEvent(event)

----

-- Listenerlocal ActorSprite = class("ActorSprite",cc.Node)function ActorSprite:initEventListener()    self:enableNodeEvents()  -- cc.Node    self.eventListeners = {} -- user to delete when dtor    local Listener = cc.EventListenerCustom:create(MSG_TEST,handler(self,self.onChangeState))    local eventdispatcher = self:getEventdispatcher()    eventdispatcher:addEventListenerWithFixedPriority(Listener,1)    table.insert(self.eventListeners,Listener) endfunction DogSprite:onChangeState(event)    local dogID = event._usedata["dogID"]    local actionID = event._usedata["actionID"]    local eventname = event:getEventname()end

cc.Director:getInstance():getEventdispatcher():removeEventListener(var)

10 ListVIEw

-- 让单个Item 在ListVIEw 水平居中ListVIEw:setGravity(ccui.ListVIEwGravity.centerHorizontal)

11

cc.SpriteFrameCache:getInstance():addSpriteFrames("zwoptex/grossini.pList")

12 eventListener

注意 前置层是否有layout，layout默认阻挡触摸

local function ontouchEvent(touch,event)            if eventType == "began" then                return self:ontouchBegan(touch,event)            elseif eventType == "moved" then                self:ontouchmoved(touch,event)            elseif eventType == "ended" then                self:ontouchended(touch,event)            elseif eventType == "cancelled" then                self:ontouchCancelled(touch,event)            end        end        self._touchListener = nil        local Listener = cc.EventListenertouchOneByOne:create()        Listener:setSwallowtouches(true)        Listener:registerScriptHandler(self.ontouchBegan,cc.Handler.EVENT_touch_BEGAN )        Listener:registerScriptHandler(self.ontouchmoved,cc.Handler.EVENT_touch_MOVED )        Listener:registerScriptHandler(self.ontouchended,cc.Handler.EVENT_touch_ENDED )        Listener:registerScriptHandler(self.ontouchCancelled,cc.Handler.EVENT_touch_CANCELLED )        local eventdispatcher = self:getEventdispatcher()        eventdispatcher:addEventListenerWithSceneGraPHPriority(Listener,self)

13 scheduler

scheduleScriptFunc

self.timer_schedulehandler = CCDirector:sharedDirector():getScheduler():scheduleScriptFunc(matchroom_ui.timefunction,1,false)

14 帧事件

local node = cc.csloader:createNode("Node.csb")    node:setposition(cc.p(100,100))    self.parent:addChild(node)    local action = cc.csloader:createTimeline("Node.csb")    node:runAction(action)    action:gotoFrameAndplay(0,false)    local function onFrameEvent(frame)        if nil == frame then            return        end        local str = frame:getEvent()        cclog("frame event:" .. str)        if str == "end" then            node:removeFromParentAndCleanup(true)        end        end    action:setFrameEventCallFunc(onFrameEvent)end

15. c 与 c++ 混合编程

#if __cplusplusextern "C" {#endif/*....*/#if __cplusplus}#endif

16 平台判断

local targetPlatform = cc.Application:getInstance():getTargetPlatform()

17 androID uuID

//获得独一无二的Psuedo IDpublic static String getUniquePsuedoID() {       String serial = null;       String m_szDevIDShort = "35" +             Build.BOARD.length()%10+ Build.BRAND.length()%10 +             Build.cpu_ABI.length()%10 + Build.DEVICE.length()%10 +             Build.disPLAY.length()%10 + Build.HOST.length()%10 +             Build.ID.length()%10 + Build.MANUFACTURER.length()%10 +             Build.MODEL.length()%10 + Build.PRODUCT.length()%10 +             Build.Tags.length()%10 + Build.TYPE.length()%10 +             Build.USER.length()%10 ; //13 位    try {        serial = androID.os.Build.class.getFIEld("SERIAL").get(null).toString();       //API>=9 使用serial号        return new UUID(m_szDevIDShort.hashCode(),serial.hashCode()).toString();    } catch (Exception exception) {        //serial需要一个初始化        serial = "serial"; // 随便一个初始化    }    //使用硬件信息拼凑出来的15位号码    return new UUID(m_szDevIDShort.hashCode(),serial.hashCode()).toString();

18.javah 使用

//进入到 src 目录// -d -- 输出目录javah -d ../jni [com.xxxx.xxx (packagename)].Classname

19 cocos Ref

Ref::~Ref(){#if CC_ENABLE_SCRIPT_BINDING && !CC_ENABLE_GC_FOR_NATIVE_OBJECTS    // if the object is referenced by Lua engine,remove it    if (_luaID)    {        // add follow 2 lines		ScriptEngineProtocol* pEngine = ScriptEngineManager::getInstance()->getScriptEngine();		if (pEngine)			ScriptEngineManager::getInstance()->getScriptEngine()->removeScriptObjectByObject(this);    }    else    {        ScriptEngineProtocol* pEngine = ScriptEngineManager::getInstance()->getScriptEngine();        if (pEngine != nullptr && pEngine->getScriptType() == kScriptTypeJavaScript)        {            pEngine->removeScriptObjectByObject(this);        }    }#endif#if CC_REF_LEAK_DETECTION    if (_referenceCount != 0)        untrackRef(this);#endif}
