cocos2d-x TestLua 之 CCFollow CCTargetedAction

--跟随动作
local function ActionFollow()
    centerSprite(1)
    man:setPosition(ccp(-200, size.height / 2))
    local move = CCMoveBy:create(2, ccp(100, 0))
    local moveBack = move:reverse()
    local scale = CCScaleBy:create(2,2)
    local seq = CCSequence:createWithTwoActions(move,scale)
    local rep = CCRepeatForever:create(seq)
    man:runAction(seq)
    
    --CCFollow动作，可以让一个节点跟随另一个节点做位移。CCFollow经常用来设置layer跟随sprite，可以实现类似摄像机跟拍的效果效果是精灵在地图上移动，地图也会跟着移动，但是精灵仍然是在整个界面的中心位置。
    --参数1为跟随目标结点，参数2为边界矩形
    layer:runAction(CCFollow:create(man,CCRectMake(0,0,size.width*2,30)))
    --下面写法代表无边界
    layer:runAction(CCFollow:create(man))
    
    --[[
    local sp = CCSprite:create("Icon.png")
    sp:setPosition(ccp(100,200))
    layer:addChild(sp)
    sp:runAction(CCFollow:create(man))
    --sp:runAction(move:reverse())
    ]]--
end

 --改变动作执行对象CCTargetedAction通常默认的动作执行对象是调用runAction的对象，而CCTargetedAction可以改变动作执行对象。CCTargetedAction* t = CCTargetedAction::create(sprite2, moveto);sprite->runAction(CCSequence::create(moveto, t, moveto, NULL));sprite先moveto，然后sprite2执行moveto，最后sprite执行moveto。
local function ActionsTargeted()
    centerSprite(2)
    
    local jump1 = CCJumpBy:create(2,ccp(0,0),300,3)
    local jump2 = CCJumpBy:create(2,ccp(0,0),300,3)
    
    local ro1 = CCRotateBy:create(2,360)
    local ro2 = CCRotateBy:create(2,360)
    
    local tar1 = CCTargetedAction:create(whitegirl,jump2)
    local tar2 = CCTargetedAction:create(whitegirl,ro2)

    local arr = CCArray:create()
    arr:addObject(jump1)
    arr:addObject(tar1)
    arr:addObject(tar2)
    arr:addObject(ro1)
    
    blackgirl:runAction(CCSequence:create(arr))
