cocos2dx的runAction: 反復運行,多個動作連接運行,多個動作同一時候運行的實現

cocos2dx的 runAction,假設某個動作重復運行用cc.RepeatForever:create,

多個動作連接運行用cc.Sequence:create,多個動作同一時候運行用cc.Spawn:create.

反復運行某個動作cc.RepeatForever:create

local action = cc.FadeOut:create(3)--淡出
local action = cc.FadeIn:create(3) -- 漸入
local action = cc.RotateBy:create(3.0,360) -- 旋轉
local action = cc.ScaleTo:create(3,0.1) --  縮放

cc.RepeatForever:create(某動作)--一個動作不斷反復運行用

反復運行某個動作n次,用 cc.Repeat:create

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

精巧n秒,用DelayTime,使用方法例如以下: 

cc.DelayTime:create(1.4)

多個動作的runAction

一個運行完成后再連接還有一個,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) -- 漸入
    sprite2:runAction(cc.Sequence:create(action,action2,action)) 

 

多個動作同一時候變化,用cc.Spawn:create

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

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

實例示范:

    local screen = cc.Director:getInstance():getRunningScene()
    local action1 = cc.ScaleTo:create(0.5, 1) --放大 參數:時間和縮放尺寸
    local action2 = cc.MoveTo:create(0.5, ccp(300,330)) --移動到某位置
    local action3 = cc.ScaleTo:create(0.2, 0.6) --縮小 參數:時間和縮放尺寸
    local action4 = cc.FadeOut:create(2)--淡出
    local action5 = cc.MoveTo:create(2, ccp(300,450)) --移動到某位置


    --復位 以便讓動畫反復
    local action6 = cc.FadeIn:create(0.01)--漸入
    local action7 = cc.MoveTo:create(0.01, ccp(300,300)) --移動到某位置

    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運行一個動作
    -- sprite:runAction(cc.Spawn:create(action1,action2))--cc.Spawn:create同一時候運行多個動作
    -- sprite:runAction(cc.Sequence:create(cc.Spawn:create(action1,action2),action3,cc.Spawn:create(action4,action5)))--cc.Sequence:create循序運行多個動作
    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(某動作)反復運行某個動作

    screen:addChild(sprite)

action中回調方法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)))
