我要建一个视频播放器和我还挺停留在音量滑块部分。这是一个YouTube式的垂直滑块,这意味着如果滑块是在顶部位置量应该是100%,如果将滑块拖动到下方位置的声音应该是0。目前,它在做什么,我想要的正好相反:(
I'm building a video player and am kinda stuck at the volume slider part. It's a YouTube style vertical slider, meaning if the slider is in the top position volume should be 100% and if the slider is dragged to the bottom position sound should be 0. Currently it's doing the opposite of what I want :(
拖动滑块降低将会使声音变得更大,而向上拖动会降低它。
Dragging the slider down will make the sound louder, while dragging up lowers it.
下面是低于处理音量滑块我的code。
Here is my code below dealing with the volume slider.
// Sound Controller Settings ······························
soundController = new SoundController();
soundContrColor = soundController.colorChip;
soundContrGray = soundController.grayCover;
soundContrGray.visible = false;
soundController.visible = true;
soundController.buttonMode = true;
soundController.soundSlider.addEventListener(MouseEvent.MOUSE_DOWN, sliderDown);
// SoundController Button Mouse Events ························
public function sliderDown(event:MouseEvent):void
{
soundController.soundSlider.startDrag(false, dragBounds);
soundController.soundSlider.addEventListener(MouseEvent.MOUSE_MOVE, sliderMove);
soundController.soundSlider.addEventListener(MouseEvent.MOUSE_UP, sliderUp);
soundContrGray.visible = true;
}
public function sliderMove(event:MouseEvent):void
{
soundContrGray.height = soundController.soundSlider.y;
userVolume = Math.round(((soundContrGray.y * soundContrGray.height) / 10) - 4);
//userVolume = soundContrGray.height;
setVolume(userVolume);
trace("soundController.mouseY = "+soundController.soundSlider.y);
trace("soundContrColor.height = "+Math.round(soundContrGray.height));
trace("userVolume = "+userVolume+"\r");
event.updateAfterEvent();
}
public function sliderUp(event:MouseEvent):void
{
lastVolPoint = soundContrGray.height;
setVolume(userVolume);
event.updateAfterEvent();
soundController.soundSlider.stopDrag();
soundController.soundSlider.removeEventListener(MouseEvent.MOUSE_MOVE, sliderMove);
soundController.soundSlider.removeEventListener(MouseEvent.MOUSE_UP, sliderUp);
}
[微量]当我一路拖到顶部:
[TRACES] when I drag all the way to the top:
soundController.mouseY = 6
soundContrGray.height = 6
userVolume = 0
[微量]当我拖累一路走低:
[TRACES] when I drag all the way down:
soundController.mouseY = 56
soundContrGray.height = 56
userVolume = 30
我相信这是问题所在:
I believe this is where the problem lies:
userVolume = Math.round(((soundContrGray.y * soundContrGray.height) / 10) - 4);
在( - 4)。是一个偏移值,所以当你拖动它都将其关闭的方式,它的0,而不是4 的 我需要以某种方式扭转这一点,所以在上面的痕迹会掉...下去会使userVolume = 4和上升将使其30。
The (-4) is an offset value so when you drag it all the way to turn it off, it's 0 and not 4. I need to reverse this somehow, so the traces above will swap... going down will make userVolume = 4 and going up will make it 30.
在此先感谢任何人,需要看看这个! :)
Thanks in advance for anyone that takes a look at this one! :)
我一定是失去了一些东西,因为它不能被这个简单的,可以吗?
I must be missing something because it can't be this simple, can it?
userVolume = 30-Math.round(((soundContrGray.y * soundContrGray.height) / 10) - 4);
