Quick Cocos2dx 初步战斗

呵呵，图片先来一发：

最近懒，很懒，连我自己都觉得有点可耻了。

但是实在没有什么东西啊，温水煮青蛙的什么的。

吐槽完成，以上。

目前完成了简单的战斗部分，AI还需要抽出来。

然后突然之间想到手游的帧频是60fps/s，然后就放弃了之前比较平滑的CCMoveTo，换成了每帧去计算坐标。

还增加了掉血计算与表现，与死亡逻辑处理。

虽然处理得不是很干净，但是这个是后续需要优化的部分。

本次的主要用到的知识点：

framework.scheduler

framework.transition

写这篇blog的目的是在于给自己一点动力，能够一步一个脚印去记录自己。

主要更新的代码部分：

GameUnit.lua:增加了死亡逻辑处理

GameUnit.lua

 local GameUnit = class("GameUnit", function()
     return display.newNode()
 end)
 local scheduler = import("framework.scheduler")
 local Progress = import("app.views.Progress")

         :addEventListener(clas.CHANGE_STATE_EVENT, handler(self, self.onStateChange))
         :addEventListener(clas.KILL_EVENT, handler(self, self.onKilled))
         :addEventListener(clas.HP_CHANGED_EVENT, handler(self, self.onHpChanged))
         :addEventListener(clas.EXP_CHANGED_EVENT, handler(self, self.onExpChanged))

     self.player = hero
     self:initDisplay()
 end

 function GameUnit:onStateChange( event )
     self:updateShapeDisplay(self.player:getState())
 end

 --更新角色显示{"anim_walk","anim_eat","anim_placeladder","anim_idle","anim_ladderwalk","anim_laddereat","anim_death"}
 function GameUnit:updateShapeDisplay(state)
     local animname = "anim_idle"
     if state == "walking" then
         animname = "anim_walk"
     elseif state == "firing" then
         animname = "anim_eat"
     elseif state == "dead" then
         animname = "anim_death"
     end
     printInfo("GameUnit state changed to %s playing : %s", state, animname)

         local animation = self.shape:getAnimation()
         animation:setSpeedScale(0.6)
         animation:play(animname)
         self:setPosition(self.player:getX(), self.player:getY())
         self:setScaleX(self.player:getDirection())

     end

     if self.player:isDead() then
         scheduler.performWithDelayGlobal(handler(self, self.autoRemove), 1.5)
     end
 end

 function GameUnit:onKilled( event)

 end

             self:removeSelf()
         end
         })

     self.shape = shape
        self:updateShapeDisplay(self.player:getState())
        shape:setAnchorPoint(CCPoint(0.5,))
        self:addChild(shape)

     --角色血条
     self.hpbar = Progress.new("progres_bg.png","progress.png")
     self.hpbar:pos(0.5, shape:getContentSize().height)
     self:addChild(self.hpbar)
 end
 --传入|更新数据
 function GameUnit:setData()
     -- body
 end
 --取得数据
 function GameUnit:getData()
     return self.hero
 end
 --添加事件:重复利用这个对象的时候会用到
 function GameUnit:addEvents()

 --移除事件:重复利用这个对象的时候会用到
