【COCOS2DX-游戏开发之三八】ClippingNode 制作标题闪亮特效

-- 1.创建模板、ClippingNode(裁剪节点)
local stencil = display.newSprite("game_title.png")

local clipper = cc.ClippingNode:create()
clipper:setStencil(stencil)
-- clipper:setInverted(true)
clipper:setAlphaThreshold(0)

-- 2.标题和光效
local spr_title = display.newSprite("game_title.png")
local spark = display.newSprite("spark.png")

clipper:addChild(spr_title)
clipper:addChild(spark)
clipper:setPosition(cc.p(300, 300))
self:addChild(clipper)

-- 3.光效移动、自动裁剪
local sz = spr_title:getContentSize()

local move = cc.MoveTo:create(0.6, cc.p(sz.width, 0))
local delay1 = cc.DelayTime:create(0.5)
local move_back = cc.MoveTo:create(0.6, cc.p(-sz.width, 0))
local delay2 = cc.DelayTime:create(0.5)
local seq = cc.Sequence:create(delay1, move, delay2, move_back)
local repeatAction = cc.RepeatForever:create(seq)
spark:runAction(repeatAction)
