我在调试音频滑块时遇到了困难。我很确定我的问题在于我的一种方法changeVolumeRedFireball
只是以非常快的速度不断重复。在我的游戏中,我每隔一段时间就会听到一个小故障的声音,所以这似乎是相关的。我在方法内部追踪了“输出”,并很快发现它正在以很高的速度重复。
问题是,我不知道这是从哪里来的!另一个注意事项。这只会在我按住滑块时开始重复,因此激活changeVolumeRedFireball
fromdragSliderRedFireball
我确实有来自其他类的其他方法引用此类中的方法。他们只能访问playSoundRedFireball
,stopSoundRedFireball
虽然,所以我不明白为什么会有任何影响。此外,这个类是由我的文档类在游戏启动时实例化的。如果需要,我想我会从文档类中放入相关代码,但我只是认为它根本不会影响这个问题。
