cocos-lua学习笔记(九)动作

下面是所有动作相关的接口，摘自《cocos2d-Lua基础》

瞬时动作：

1.place：节点放置到某一位置

2.Flipx与Flipy：只能用于精灵，沿x或y轴反转

3.Show与Hide 显示和隐藏节点

4.CallFunc 动作结束的，启动的逻辑

有限时间动作

1.MoveTo 与 MoveBy

2.JumTo 与JumpBy

3.BezierTo 与BezierBy

4.ScaleTo与ScaleBy

5.RotateTo与RotateBy

6.FadeIn、FadeOut和FadeTo

7.TintTo 与TintBy

8.Blink

9.Animation

复合动作

1.DelayTime

2.Repeat与RepeatForever

3.Spawn

4.Sequence

5.Follow

变速动作

1.Speed

2.ActionBase ->这里有很多图

节点动作接口

node:runAction()

node:stopAction()

node:stopAllActions

node:stopAction(action)

node:stopActionByTag(tag)

node:setTag(tag)

action:setTag(tag)

node:getActionByTag(tag)

action:stopActionByTag(tag)

具体的接口怎么使用，直接上一个Demo展示

local MainScene = class("MainScene", function()
    return display.newScene("MainScene")
end)

function MainScene:ctor()
    self.backgroundLayer = display.newColorLayer(cc.c4f(128,128,128,255))
    self.backgroundLayer:addTo(self)

    -- preload frames to cache
    display.addSpriteFrames("grossini-aliases.plist", "grossini-aliases.png")
    
    -- run actions: 1 to 9
    self:run(1)
end

function MainScene:run(actionNum)
    self["action" .. actionNum](self)
end
