Quick Cocos2dx 与 EnterFrame事件

利用EnterFrame做出行走的效果，效果图如下：

具体操作：

1 给self多加一个bg1用作与bg无限循环换位

2 在AnotherScene:onEnter方法里面新增onEnterFrame的排成

3 写了一个简单的onEnterFrame方法用作每帧去更新

完整代码如下：

local AnotherScene = class("AnotherScene", function()
    return display.newScene("AnotherScene")
end)

function AnotherScene:ctor()
    self.speed = 2;
    self.curBehaviorId = 1;
    self.layer = display.newLayer()
    self:addChild(self.layer)
    self.layer:setTouchEnabled(true)
    self.behaviors = {"anim_walk","anim_eat","anim_placeladder","anim_idle","anim_ladderwalk","anim_laddereat","anim_death"};
    self.bg = display.newSprite("battle.png",display.cx, display.cy)
    self.bg1 = display.newSprite("battle.png",display.cx+self.bg:getContentSize().width, display.cy)
    self.layer:addChild(self.bg)
    self.layer:addChild(self.bg1)
end

function AnotherScene:onTouch(event, x, y)
    print("Touched at %d %d",x,y)
    self.curBehaviorId = self.curBehaviorId + 1;
    if self.curBehaviorId > #self.behaviors then
        self.curBehaviorId = 1;
    end
    print("Now playing ", self.curBehaviorId , #self.behaviors, self.behaviors[self.curBehaviorId])
    self.animation:play(self.behaviors[self.curBehaviorId])
end

function AnotherScene:onEnterFrame(dt)
    local tempX = self.bg:getPositionX();
    local tempW = self.bg:getContentSize().width;
    tempX = tempX - self.speed;
    if tempX <= display.cx - tempW then
        self.bg:setPositionX(display.cx + tempW)
    else
        self.bg:setPositionX(tempX)
    end

    tempX = self.bg1:getPositionX();
    tempW = self.bg1:getContentSize().width;
    tempX = tempX - self.speed;
    if tempX <= display.cx - tempW then
        self.bg1:setPositionX(display.cx + tempW)
    else
        self.bg1:setPositionX(tempX)
    end
end

function AnotherScene:onEnter()
    ui.newTTFLabel({text = "Yo! Yo! Check Out!", size = 64, align = ui.TEXT_ALIGN_CENTER})
        :pos(display.cx, display.cy)
        :addTo(self.layer)

    local manager = CCArmatureDataManager:sharedArmatureDataManager()
    manager:addArmatureFileInfo("Zombie.png","Zombie.plist","Zombie.xml")
    local zombie = CCNodeExtend.extend(CCArmature:create("Zombie_ladder"))
    zombie:connectMovementEventSignal(function(__evtType, __moveId)
            echoInfo("movement, evtType: %d, moveId: %s", __evtType, __moveId)
        end)
    self.animation = zombie:getAnimation()
    self.animation:setAnimationScale(0.5)
    self.animation:play("anim_walk")
    zombie:setPosition(display.cx, display.cy)
    zombie:setScaleX(-1)
    self.layer:addChild(zombie)
    self.layer:addTouchEventListener(function(event,x,y)
        return self:onTouch(event, x,y)
        end)    
    self.layer:setTouchEnabled(true)
    self:scheduleUpdate(function(dt) 
        self:onEnterFrame(dt)
    end)
end
return AnotherScene

game003即为当前的项目，问我为啥没有把项目分出来，我只能说我.....很.....懒。
