quick-cocos2d-x lua编写简单的场景

一、先看看我的目录结构

二、CCloud.lua

require("app.CResource")local m_rc = RcCloudCCloud = class("CCloud", function()return CCSprite : create(m_rc.m_fname)end)CCloud.winSize = CCDirector : sharedDirector() : getVisibleSize()local function call_setPos(this)local sz = this : getContentSize()this : setPosition ( ccp( -sz.width,  this.winSize.height / (math.random(5))) )endfunction CCloud : create(pLayer)    local cloud = CCloud.new()pLayer : addChild(cloud)    math.randomseed(os.time())local sz = cloud : getContentSize()local by = CCMoveBy:create(20.0, ccp(cloud.winSize.width + 2 * sz.width, 0))local pFun = CCCallFuncN : create (call_setPos)local pRepeat = CCRepeatForever : create (CCSequence:createWithTwoActions ( pFun, by) )cloud : runAction(pRepeat)endfunction CCloud:ctor()endreturn CCloud

二、CMessage.lua

require("app.CResource")local m_rc = RcMessageCMessage = class("CMessage", function()    return CCSprite : create(m_rc.m_fname)end)CMessage.winSize = CCDirector : sharedDirector() : getVisibleSize()CMessage.m_lbl = NULL-- 设置文本function CMessage : setText(text)    self : setPosition(ccp(self.winSize.width / 2.0, self.winSize.height / 2.0))    self.m_lbl : setString(text)    local sz = self : getContentSize()    self.m_lbl : setPosition(ccp(sz.width / 2.0, sz.height / 2.0))end-- 隐藏local function  call_hide(this)    this : removeFromParent()end-- 提示function CMessage : create(pLayer, text)    local pMsg = CMessage.new()    pLayer : addChild(pMsg)    pMsg.m_lbl = CCLabelTTF : create("", "Tohoma", 35)    pMsg : addChild(pMsg.m_lbl)    pMsg : setText(text)    pMsg : setOpacity(0)    pMsg.m_lbl : setOpacity(0)    local ptOri = ccp(pMsg : getPosition())    local dtPos = ccp(0, 50)    pMsg : setPosition(ccp(ptOri.x, ptOri.y - dtPos.y))    pMsg : setVisible(true)        -- 创建移动动画    local moveByIn  = CCMoveBy : create(0.2, dtPos)    local moveByOut = CCMoveBy : create(0.2, dtPos)        -- 由无变亮、由亮变无    local in1  = CCFadeIn:create(0.2)    local out1 = CCFadeOut:create(0.2)        local spwanIn    = CCSpawn : createWithTwoActions(moveByIn, in1)    local spwanOut   = CCSpawn : createWithTwoActions(moveByOut, out1)    local delay  = CCDelayTime:create(2.0)        -- 消失动作    local fun = CCCallFuncN : create(call_hide)        -- 最终组合动作    local seqArr = CCArray : create()    seqArr : addObject(spwanIn)    seqArr : addObject(delay)    seqArr : addObject(spwanOut)    seqArr : addObject(fun)     local seq = CCSequence:create(seqArr)    pMsg : runAction(seq)            local in2 = CCFadeIn:create(0.2)    local out2 = CCFadeOut:create(0.2)    local delay2  = CCDelayTime:create(2.0)    local seqArr2 = CCArray : create()    seqArr2 : addObject(in2)    seqArr2 : addObject(delay)    seqArr2 : addObject(out2)    local seq2 = CCSequence:create(seqArr2)    pMsg.m_lbl : runAction(seq2)endfunction CMessage:ctor()endreturn CMessage

三、CResource.lua

local winSize = CCDirector : sharedDirector() : getVisibleSize()-- 定义主场景资源类RcMainScene = {}RcMainScene.m_bg = {name = "bg.jpg", pos = ccp(winSize.width / 2.0, winSize.height / 2.0)}RcMainScene.m_cityMenu = {name = "", pos = ccp(winSize.width / 2.0, winSize.height / 2.0), tag = 100}RcMainScene.m_mine = {name = "4.png", pos = ccp(-310.3, 130.6),tag = 101}RcMainScene.m_shop = {name = "2.png", pos = ccp(-306.7, -96.2), tag = 102}RcMainScene .m_workShop= {name = "10.png", pos = ccp(-123.1, -185.0), tag = 103}RcMainScene .m_bar = {name = "10.png", pos = ccp(107.3,  -185.0), tag = 104}RcMainScene .m_chooseGen= {name = "6.png",  pos = ccp(346.1,  -120.2),  tag = 105}RcMainScene .m_train    = {name = "5.png",  pos = ccp(348.5,  50.2),    tag = 106}RcMainScene .m_trade    = {name = "8.png",  pos = ccp(242.9,  272.2),   tag = 107}RcMainScene .m_inherit  = {name = "11.png", pos = ccp(-9.1,   287.8),   tag = 108}RcMainScene .m_genMap   = {name = "14.png", pos = ccp(-252.7, 289.0),   tag = 109}RcMainScene .m_shrine   = {name = "13.png", pos = ccp(6.5,    52.6),    tag = 110}-- 定义消息资源类RcMessage = {}RcMessage.m_fname = "msg.png"-- 云资源RcCloud = {}RcCloud.m_fname = "cloud.png"

四、scenes/MainScene.lua

require("app.CCloud")require("app.CMessage")require("app.CResource")local m_rc = RcMainScene-- 定义场景类local MainScene = class("MainScene", function()    return display.newScene("MainScene")end)-- menuItem按钮请求回调函数local function call_select(tag, pSender)    tag = tag - 100;    local pCityName = {"矿区", "商店", "玉石作坊", "酒馆", "点将台", "校场", "贸易中心", "传承塔", "名将图鉴", "战神殿"}     local pMsg = "没有开启【" .. pCityName[tag] ..
