好久没有用quick引擎开发了，最近又要整quick了，有种熟悉感。
今天主要记录一下研究了半天的大转盘的实现。
如图：
1、主要精华如下：
local ALLROATE = 360--360度
local num = 10
--转盘角度数据
local zhuanpanData =
{
{start = (num-10)*ALLROATE/num + 0, ended = (num-9)*ALLROATE/num},
{start = (num-9)*ALLROATE/num + 1, ended = (num-8)*ALLROATE/num},
{start = (num-8)*ALLROATE/num + 1, ended = (num-7)*ALLROATE/num},
{start = (num-7)*ALLROATE/num + 1, ended = (num-6)*ALLROATE/num},
{start = (num-6)*ALLROATE/num + 1, ended = (num-5)*ALLROATE/num},
{start = (num-5)*ALLROATE/num + 1, ended = (num-4)*ALLROATE/num},
{start = (num-4)*ALLROATE/num + 1, ended = (num-3)*ALLROATE/num},
{start = (num-3)*ALLROATE/num + 1, ended = (num-2)*ALLROATE/num},
{start = (num-2)*ALLROATE/num + 1, ended = (num-1)*ALLROATE/num},
{start = (num-1)*ALLROATE/num + 1, ended = (num-0)*ALLROATE/num},
}
local duration = 5 --转动持续时间
local rotateNum = 5 --转动圈数
local function Act()
local targetIdx = 7 --服务器传来的值。
scheduler.performWithDelayGlobal(function(dt)
local targetData = zhuanpanData[targetIdx]
local rotateAngle = - math.random(targetData.start, targetData.ended) - 360 * rotateNum
print("随机角度是：", rotateAngle)
--第二次需要重置坐标点
if lastAngle ~= 0 then
self:rotateSprite(self.panbg, duration, rotateAngle + lastAngle)
else
self:rotateSprite(self.panbg, duration, rotateAngle)
end
lastAngle = -360 - rotateAngle - 360 * rotateNum
end, 0)
end
2、封装转盘的主要method，直接复制调用然后传参数就可以啦，请仔细看参数说明
-- sprite 精灵
-- time 旋转的时间
-- rotateAngle_ 旋转的角度
local function rotateSprite(sprite, time, rotateAngle_)
local action = cc.RotateBy:create(time, rotateAngle_)
local easeAction = cc.EaseCubicActionInOut:create(action)
sprite:runAction(easeAction)
end
如果有更好的实现效果请，留言一同探讨。
