local action1 = cc.RepeatForever:create(cc.Sequence:create(a1, a2, a2:reverse()))
local action2 = cc.RepeatForever:create(cc.Sequence:create(a1:clone(), a2:clone(), a2:reverse()))//因为action1跟action2是同时执行的，所以action2的动作序列的创建需要将a1、a2克隆出来

sp2:setAnchorPoint(cc.p(1.0,1.0))
//sp1:setAnchorPoint(cc.p(0,0))  sp1的锚点有个默认ccp(0.5,0.5)
sp1:runAction(action1)
sp2:runAction(action2)
