看到网上有相关抽奖轮盘的实现，刚好自己也在做相关功能，就写了一个，能实现任意个数的抽奖圆盘,上传的GIF帧数有点少（只有10帧），博客不允许大图片没办法，cocos2d-x版本3.3，需要源码资源的可以给我发信息
LuckyRound = class("LuckyRound", function ()
return cc.Layer:create()
end)
function LuckyRound:ctor()
self.bg = cc.Sprite:create("res/luck001.png")
self.bg:setPosition(cc.p(480,320))
self.bg:setAnchorPoint(cc.p(0.5,0.5))
self:addChild(self.bg)
local bgSize = self.bg:getContentSize()
self.pointsBg = cc.Sprite:create("res/luck002.png")
self.pointsBg:setPosition(cc.p(bgSize.width/2,bgSize.height/2))
self.bg:addChild(self.pointsBg)
self.pointsBg:setGlobalZOrder(2)
local centerMarkImg = cc.Sprite:create("res/luck011.png")
centerMarkImg:setPosition(cc.p(bgSize.width/2,bgSize.height/2))
self.bg:addChild(centerMarkImg)
local selectImg = cc.Sprite:create("res/luck012.png")
selectImg:setPosition(cc.p(bgSize.width/2,bgSize.height/2+50))
self.bg:addChild(selectImg)
local actionRotate1 = cc.RotateBy:create(1, 90)
local actionRotate2 = cc.RotateBy:create(1, 360)
local selectedItemNum = 1
local actionRotate3 = cc.RotateBy:create(2, 720)
local actionRotate4 = cc.RotateBy:create(3, 180+20-(selectedItemNum*45))
local seq = cc.Sequence:create(actionRotate1,actionRotate2,actionRotate3,actionRotate4)
self.pointsBg:runAction(seq)
local posList = self:getItemsPos(7,120)
for i=1,7 do
local imgSrc = string.format("res/luck0%02d.png", i+2)
local sprite = cc.Sprite:create(imgSrc)
sprite:setAnchorPoint(0.5,0.5)
sprite:setPosition(posList[i].x+166,posList[i].y+166)
self.pointsBg:addChild(sprite)
local updateRotate = function ()
sprite:setRotation(-(self.pointsBg:getRotation()))
end
schedule(sprite,updateRotate,0.1)
end
end
--获取个数，半径为radis 的各个顶点的位置
function LuckyRound:getItemsPos(itemNum,radis)
local e_rot= 2*math.pi/itemNum;
local posList = {}
for i=1,itemNum do
posList[i] = {}
local rot = i*e_rot + 0.5*e_rot;
posList[i].x=radis*math.sin(rot);
posList[i].y=radis*math.cos(rot);
end
return posList
end
return LuckyRound
GIF好像没办法播放！！！！
