我正在使用Corona SDK创建两个按钮,一个用于播放音乐,另一个用于停止。该程序工作正常,直到我创建了停止按钮,但没有任何效果。没有音频。有人可以帮我解决这个问题吗?
local widget = require("widget")
display.setStatusBar(display.HiddenStatusBar)
centerX = display.contentWidth * .5
centerY = display.contentHeight * .5
-- Background
local bg = display.newImageRect("bg_iPhone.png", 1100, 3200)
bg.x = centerX
bg.y = centerY
local isAudioOn = true
local soundJump = audio.loadSound("boing.mp3") --[[loadSound is for animations]]--
local soundMusic = audio.loadStream("HappyPants.wav") --[[loadStream is for background music]]--
--Sound function to play music
local function playSound()
if isAudioOn then
audio.play(soundMusic)
print("Boing!")
end
end
-- Button Function that controls what happens after button is pressed
local function buttonHit(action)
if action == "play" then
playSound()
elseif action == "stop" then
audio.stop(playSound)
end
end
-- Play Button
local playButton = widget.newButton{
label = "Play",
id = "play",
x = 330,
y = 500,
labelColor = { default={ 0, 19, 189 }, over={ 0, 19, 189, 1 } },
onPress = buttonHit
}
-- Stop Button
local stopButton = widget.newButton{
label = "Stop",
id = "stop",
x = 330,
y= 550,
labelColor = { default={ 0, 19, 189 }, over={ 0, 19, 189, 1 } },
onPress = buttonHit
}
您的buttonHit功能错误。
您传入参数action,但是,由于您使用的是小部件库,因此传递给该函数的唯一内容是event。另外,还给按钮提供了一个[[id,而不是一个动作。然后,此ID属于事件目标,即所按下的按钮。
您想要的是类似的东西:local function buttonHit( event )
if event.target.id == "play" then
playSound()
else
audio.stop(playSound)
end
end
