Question

这不起作用，我想要的。当我这样做时它只从黑色转换为白色但是如果我删除参数textToFlash并将其留空并将myTextObject放在其工作的函数中的其余textToFlash对象的位置并闪烁不同的颜色。

local myTextObject = display.newText("Hello, World", 160, 25, "Arial", 60)

function flashing_text(textToFlash)
    local r = math.random(0,100)
    local g = math.random(0,100)
    local b = math.random(0, 100)

    if(textToFlash.alpha < 1) then
        textToFlash:setFillColor(r/100,g/100,b/100)
        transition.to( textToFlash, {time=490, alpha=1})
    else 
        transition.to( textToFlash, {time=490, alpha=0.1})
    end
end
txt_flash = timer.performWithDelay(550, flashing_text(myTextObject), 0)

有人能做到这一点吗？任何帮助或反馈将不胜感激

为了让您的功能发挥作用。您必须在计时器功能中添加功能（）结束。像这样 timer.performWithDelay（延迟，函数（）callYourOtherfunction（）结束，0）

local myTextObject = display.newText("Hello, World", 160, 25, "Arial", 60)

function flashing_text(textToFlash)
    local r = math.random(0,100)
    local g = math.random(0,100)
    local b = math.random(0, 100)

    if(textToFlash.alpha < 1) then
        textToFlash:setFillColor(r/100,g/100,b/100)
        transition.to( textToFlash, {time=490, alpha=1})
    else 
        transition.to( textToFlash, {time=490, alpha=0.1})
    end
end
txt_flash = timer.performWithDelay(550, function() flashing_text(myTextObject) end, 0)

干杯。在我的模拟器伙伴中工作。快乐的编码。
