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

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

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, ccp(300,450)) --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, ccp(300,300)) --移动到某位置

    local sprite = cc.Sprite:create(fonts/number_green.png) 
    sprite:setTextureRect(cc.rect(120, 0, 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,action2),action3,cc.Spawn:create(action4,action5),cc.Spawn:create(action6,action7))))--cc.RepeatForever:create(某动作)重复执行某个动作

    screen:addChild(sprite)
