cocos2dx的runAction: 重复执行,多个动作连接执行,多个动作同时执行的实现

cocos2dx的 runAction,如果某个动作反复执行用cc.RepeatForever:create,

多个动作连接执行用cc.Sequence:create,多个动作同时执行用cc.Spawn:create.

重复执行某个动作cc.RepeatForever:create

local action = cc.FadeOut:create(3)--淡出
local action = cc.FadeIn:create(3) -- 渐入
local action = cc.RotateBy:create(3.0,360) -- 旋转
local action = cc.Scaleto:create(3,0.1) --  缩放

cc.RepeatForever:create(某动作)--一个动作不断重复执行用

重复执行某个动作n次,用cc.Repeat:create

local rep1 = cc.Repeat:create(seq,10)

静止n秒,用DelayTime,用法如下:

cc.DelayTime:create(1.4)

多个动作的runAction

一个执行完毕后再连接另一个,用cc.Sequence:create

   local sprite2 = cc.Sprite:create("img/equipment/background_root.png")
    sprite2:setPosition(cc.p(visibleSize.width/2,visibleSize.height/4))
    mlayer:addChild(sprite2,10)

    local action = cc.FadeOut:create(3)--淡出
    local action2 = cc.FadeIn:create(3) -- 渐入
    sprite2:runAction(cc.Sequence:create(action,action2,action)) 

多个动作同时变化,用cc.Spawn:create

sprite:runAction(cc.Spawn:create(cc.RotateBy:create(3.0,360),cc.Scaleto:create(3,0.1)))

-------------------------------------

实例示范:

    local screen = cc.Director:getInstance():getRunningScene()
    local action1 = cc.Scaleto:create(0.5,1) --放大 参数:时间和缩放尺寸
    local action2 = cc.Moveto:create(0.5,ccp(300,330)) --移动到某位置
    local action3 = cc.Scaleto:create(0.2,0.6) --缩小 参数:时间和缩放尺寸
    local action4 = cc.FadeOut:create(2)--淡出
    local action5 = cc.Moveto:create(2,450)) --移动到某位置


    --复位 以便让动画重复
    local action6 = cc.FadeIn:create(0.01)--渐入
    local action7 = cc.Moveto:create(0.01,300)) --移动到某位置

    local sprite = cc.Sprite:create("fonts/number_green.png") 
    sprite:setTextureRect(cc.rect(120,120,28) )
    sprite:setPosition(300,300)
    sprite:setAnchorPoint(ccp(0.5,0))
    sprite:setScale(0.6)
    -- sprite:runAction(action1)--runAction执行一个动作
    -- sprite:runAction(cc.Spawn:create(action1,action2))--cc.Spawn:create同时执行多个动作
    -- sprite:runAction(cc.Sequence:create(cc.Spawn:create(action1,action2),action3,cc.Spawn:create(action4,action5)))--cc.Sequence:create循序执行多个动作
    sprite:runAction(cc.RepeatForever:create(cc.Sequence:create(cc.Spawn:create(action1,action5),cc.Spawn:create(action6,action7))))--cc.RepeatForever:create(某动作)重复执行某个动作

    screen:addChild(sprite)

action中回调方法cc.CallFunc:create()

local function removeThis()

ret:getParent():removeChild(ret,true)

Helper.nextAction()

end

--After 1.5 second,self will be removed.

ret:runAction( cc.Sequence:create(cc.DelayTime:create(1.4),cc.CallFunc:create(removeThis)))
