Flash As3 静音按钮问题
我正在尝试创建一个可以在不同场景中使用的 UI 影片剪辑。 它使用根范围中的变量来确定状态。
当我按下静音按钮时工作正常,但是当我尝试取消静音时事情会变得很奇怪。有时需要点击 2 次才能取消静音,有时需要点击更多次。看起来是随机的。 然而,静音似乎第一次起作用......
有什么想法吗?
Main Timeline:
var mute:Boolean = false;
var playerName = "Fred";
function setMute(vol)
{
var sTransform:SoundTransform = new SoundTransform(1,0);
sTransform.volume = vol;
SoundMixer.soundTransform = sTransform;
}
function toggleMuteBtn(event:Event)
{
if (mute)
{
// Sound On, Mute Off
mute = false;
setMute(1);
ui_mc.muteCross_mc.visible = false;
}
else
{
// Sound Off, Mute On
mute = true;
setMute(0);
ui_mc.muteCross_mc.visible = true;
}
}
ui_mc Action Script:
if (MovieClip(parent).mute == false)
{
muteCross_mc.visible = false;
}
mute_btn.addEventListener(MouseEvent.CLICK, MovieClip(parent).toggleMuteBtn);
I am trying to create a UI movie clip that can be used across different scenes.
It uses variables from the root scope to determine states.
When i press the mute button is works fine, however when i try to un-mute things go weird. Sometimes it takes 2 clicks to unmute, sometimes more. It seems random.
Muting however seems to work first time..
Any ideas?
Main Timeline:
var mute:Boolean = false;
var playerName = "Fred";
function setMute(vol)
{
var sTransform:SoundTransform = new SoundTransform(1,0);
sTransform.volume = vol;
SoundMixer.soundTransform = sTransform;
}
function toggleMuteBtn(event:Event)
{
if (mute)
{
// Sound On, Mute Off
mute = false;
setMute(1);
ui_mc.muteCross_mc.visible = false;
}
else
{
// Sound Off, Mute On
mute = true;
setMute(0);
ui_mc.muteCross_mc.visible = true;
}
}
ui_mc Action Script:
if (MovieClip(parent).mute == false)
{
muteCross_mc.visible = false;
}
mute_btn.addEventListener(MouseEvent.CLICK, MovieClip(parent).toggleMuteBtn);

我假设您的代码位于时间线的第一帧上。
我不会深入讨论有关 as3 中的实践的问题,但您最好使用文档类。这样代码只初始化一次。我猜当你在场景之间切换时,你会不断重新初始化,所以你最终将静音重置为 false。
要检查是否发生这种情况,只需向该脚本添加
trace("init")
,然后查看调用该脚本的频率。您还可以向您的toggleMuteBtn 函数添加跟踪以查看发生了什么静音变量是在您更改它之前。顺便说一句,我很好奇为什么你要对父
MovieClip(parent)
进行类型转换,尽管它不会导致任何问题,但没有必要,因为你可以使用父级
I'm assuming that your code is on the first frame of your timeline.
I won't go into depth with the issues regarding that practice in as3, but you might be better off using a document class. That way the code is initialized only once. I'm guessing when you're switching between the scenes, you keep re-initializing, so you end up resetting mute to false.
To check if this is happening, just add a
trace("init")
to that script, and see how often you call that., you can also add a trace to your toggleMuteBtn function to see what the mute variable is before you change it.on a side note, I'm curious why you're typecasting the parent
MovieClip(parent)
though it won't cause any problems, there is no need for it as you could just useparent
