制作一个简单的精灵套件游戏。在那里,我听起来像按钮触摸声音等AVFoundation
声音库。但有这个麻烦。点击任何按钮时,我的帧速率总是下降,这听起来不错。但是如果我把所有的声音都哑了,就没有滞后。这里是我的代码:无法理解我的精灵套装游戏中的滞后?
import AVFoundation
class GameAudio {
static let shared = GameAudio()
private var buttonClickSound = AVAudioPlayer()
private var completionSound = AVAudioPlayer()
private var swishSound = AVAudioPlayer()
private var gridSwishSound = AVAudioPlayer()
private let Volume: Float = 0.8
func setupSounds() {
print("GameAudio setupSounds()")
if let path = Bundle.main.path(forResource: SoundNames.ButtonClickSoundName, ofType: "mp3") {
let url = URL(fileURLWithPath: path)
do {
buttonClickSound = try AVAudioPlayer(contentsOf: url)
} catch {
print(error)
}
}
if let path = Bundle.main.path(forResource: SoundNames.CompletionSoundName, ofType: "mp3") {
let url = URL(fileURLWithPath: path)
do {
completionSound = try AVAudioPlayer(contentsOf: url)
} catch {
print(error)
}
}
if let path = Bundle.main.path(forResource: SoundNames.SwishSoundName, ofType: "mp3") {
let url = URL(fileURLWithPath: path)
do {
swishSound = try AVAudioPlayer(contentsOf: url)
} catch {
print(error)
}
}
if let path = Bundle.main.path(forResource: SoundNames.GridSwishSoundName, ofType: "mp3") {
let url = URL(fileURLWithPath: path)
do {
gridSwishSound = try AVAudioPlayer(contentsOf: url)
} catch {
print(error)
}
}
buttonClickSound.volume = Volume
completionSound.volume = Volume
swishSound.volume = Volume
gridSwishSound.volume = Volume
}
func playButtonClickSound() {
buttonClickSound.play()
}
func playCompletionSound() {
completionSound.play()
}
func playSwishSound() {
swishSound.play()
}
func playGridSwishSound() {
gridSwishSound.play()
}
}
在我GameViewController我打电话GameAudio.shared.setupSounds()
预加载我的所有声音。
public struct Actions {
static func buttonIsTouched(_ button: SKNode, sound: Bool, completion: @escaping() ->()) {
if button.hasActions() { return }
if sound {
GameAudio.shared.playButtonClickSound()
}
button.run(touchedButtonAction(scaleFactor: button.returnScaleFactor()), completion: completion)
}
}
class MenuNode: SKNode {
private let settings: Settings
var delegate: MenuNodeDelegate?
private let playButton = SKSpriteNode(imageNamed: SpriteNames.PlayButtonName)
private let MenuNodeTreshold: CGFloat = 12.0
init(settings: Settings) {
self.settings = settings
super.init()
setupButtons()
isUserInteractionEnabled = false
}
private func setupButtons() {
playButton.position = CGPoint(x: 0.0 - playButton.frame.size.width/2.0 - MenuNodeTreshold/2.0, y: 0.0)
addChild(playButton)
}
override func touchesEnded(_ touches: Set<UITouch>, with event: UIEvent?) {
for touch in touches {
let location = touch.location(in: self)
if playButton.contains(location) {
Actions.buttonIsTouched(playButton as SKNode, sound: settings.sound, completion: {
self.delegate?.playButtonTouched()
})
}
}
}
required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
}
我在我的游戏中使用了Actions
struct。在那里我有buttonTouchedAction()
,我用它在不同的节点。我用一个“播放”按钮从我的菜单中放了一些代码。因此,例如,我在设备上运行游戏,显示菜单节点,等待几秒钟,然后点击按钮,在我的帧频下降后,我有一秒滞后,然后场景变为游戏场景。
你能发布当你的按钮被“击中”时执行的代码吗? – Stoyan
完成它斯托扬。用一些额外的代码编辑。 –
'GameAudio'中是否存在错误的代码实现,比如使用四个'AVAudioPlayer()'来代替我的声音而不是一个?或者这没关系? –
