项目移植手记

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)

----

-- listener
local 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) 
end

function 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 __cplusplus
extern "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 ID
public 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
}
