我试图使用scalafx将mp3添加到我的scala gui中,但是我很难将其添加到场景中
这是我所拥有的,但不起作用...
val gameStage = new PrimaryStage {
title = "Game Graphics"
scene = new Scene(windowWidth, windowHeight) {
var audio = new Media(url)
var mediaPlayer = new MediaPlayer(audio)
mediaPlayer.volume = 100
mediaPlayer.play()
}
}
答案 0 :(得分:1)
似乎有一个问题是您没有使用MediaView
实例将MediaPlayer
添加到场景中。另外,最好在显示场景之前不开始播放媒体。
我认为您需要这样的东西(作为一个完整的应用程序):
import scalafx.application.JFXApp
import scalafx.application.JFXApp.PrimaryStage
import scalafx.scene.{Group, Scene}
import scalafx.scene.media.{Media, MediaPlayer, MediaView}
object GameGraphics
extends JFXApp {
// Required info. Populate as necessary...
val url = ???
val windowWidth = ???
val windowHeight = ???
// Initialize the media and media player elements.
val audio = new Media(url)
val mediaPlayer = new MediaPlayer(audio)
mediaPlayer.volume = 100
// The primary stage is best defined as the stage member of the application.
stage = new PrimaryStage {
title = "Game Graphics"
width = windowWidth
height = windowHeight
scene = new Scene {
// Create a MediaView instance of the media player, and add it to the scene. (It needs
// to be the child of a Group, or the child of a subclass of Group).
val mediaView = new MediaView(mediaPlayer)
root = new Group(mediaView)
}
// Now play the media.
mediaPlayer.play()
}
}
此外,您应该更喜欢val
而不是var
,尤其是在定义了关联变量之后无需修改它们的情况下。
顺便说一句,无法测试您的代码,因此请考虑下次发布minimal, complete and verifiable example。
