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 = ;
     self.curBehaviorId = ;
     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 + ;
     if self.curBehaviorId > #self.behaviors then
         self.curBehaviorId = ;
     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 = , 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(-)
     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。
