audio - 电晕sdk:当对象在指定区域中时播放声音

Question

我想播放这种声音

audio.play(colsound) 

当我的球穿过障碍物时(obst1和obst2之间有自由空间)

ball = display.newImage("ball.png")
    ball.x = 100; ball.y = 100
    physics.addBody(ball, "dynamic", {density=.05, bounce=0.1, friction=.2, radius=12})
    screenGroup:insert(ball)
    ball.myName = "ball"

    ----
    obst1 = display.newImage("obst1.png")
    obst1.x = 640; obst1.y = -500
    obst1.speed = 3
    physics.addBody(obst1, "static", {friction=0.5, bounce=0.3, density=.1 })
    screenGroup:insert(obst1)
    obst1.myName = "obst1"


    obst2 = display.newImage("obst2.png")
    obst2.x = 640; obst2.y = 500
    obst2.speed = 3
    physics.addBody(obst2, "static", {friction=0.5, bounce=0.3, density=.1 })
    screenGroup:insert(obst2)
    obst2.myName = "obst2"

(就像在飞扬的小鸟中，当小鸟通过管子时，会发出声音……)。

这是我用来检测碰撞并播放声音的代码，我放在Obst1和Obst2之间的物体会阻止球通过(我应该将速度设置为0还是将physics.setContinuous(假))

function onCollision (event)

    if (event.object1.myName == "obst1") or (event.object1.myName == "obst2") then 
    storyboard.gotoScene("restart", "fade", 400)
    audio.stop()

    end

    if (event.object1.myName == "obst3") then 
    audio.play(colsound)  

    end
    if (event.object1.myName == "t") then  --the transparent object
    audio.play(colsound, 1) 
    end
end

将一个物理对象放置在两个障碍物的中间并找到碰撞以播放音频。
