lua好用的代码
-- 对比新增数据
function GameStyle:valueReplace( new,old )
for k,v in pairs(new) do

--对比删除数据
function GameStyle:valueDelete( new , old )

old[k] = old[k] or {}
self:valueDelete(v,old[k] )
else
if v == 1 then

end
end
end
end
--对比数据是否发生变化
function GameStyle:checkDataChange(lastData,curData)
-- dump(lastData)

return false
end
