我想在球击中特定物体（透明障碍物）或穿过特定区域时播放特定声音。

    function onCollision(event)
    if event.phase == "began" then 
    storyboard.gotoScene("restart", "fade", 400)


    end`
    end


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


--Obstacles code




`obst1 = display.newImage("obst1.png")
obst1.x = 640; obst1.y = -500
obst1.speed = 2
physics.addBody(obst1, "static", {friction=0.5, bounce=0.3, density=.1 })
screenGroup:insert(obst1)`

`missile1 = display.newImage("missile.png")
missile1.x = 700; missile1.y = math.random(5,1090)
missile1.speed = math.random(2,6)
missile1.initY = missile1.y
missile1.amp = math.random(20,100)
physics.addBody(missile1, "static", {density=0.1, bounce=0.1, friction=.2, radius=12})
screenGroup:insert(missile1)
missile1.angle = math.random(20,100)`

那么我怎样才能让球与另一个物体碰撞并在不停止游戏的情况下开始声音（在碰撞功能上，物体碰撞的那一刻它会进入重新启动屏幕）

非常感谢 ...

因为你似乎对 Corona 很陌生，所以我试着给你一些建议和指导：

首先你应该知道如何检测碰撞：Physics Body 然后你应该知道如何处理碰撞事件：碰撞和碰撞检测 ，然后你应该知道如何播放声音：声音播放

这是我编写 mySelf 的游戏中的一个示例：

--implement the physics for the project
local physics = require "physics";
physics.start()

...

-- stones pics
stone1 = stons_shape[stoneNumber][2]
stone2 = stons_shape[stoneNumber][2]
stone3 = stons_shape[stoneNumber][2]
-- stones physics
physics.addBody (stone1,"Dynamic", stons_shape[stoneNumber][1]:get(stons_shape[stoneNumber][0]))
physics.addBody (stone2,"Dynamic", stons_shape[stoneNumber][1]:get(stons_shape[stoneNumber][0]))
physics.addBody (stone3,"Dynamic", stons_shape[stoneNumber][1]:get(stons_shape[stoneNumber][0]))

-- stones property
stone1.linearDamping = stons_shape[stoneNumber][5] * 0.03
stone1.angularDamping= 1.5
stone1.power = stons_shape[stoneNumber][3]


function onCollision (event)

    if(event.object2.myName=="stone1")or(event.object2.myName=="stone2")or(event.object2.myName=="stone3") then
        -- here one stone touches another and 
        -- and so you can play a sound 
    end
end
--"onCollision" event is for all objects having collision on each other
Runtime:addEventListener( "collision", onCollision)
