我正在学习如何为 vision pro 进行开发，并且我正在尝试制作一个简单的气泡，当与它交互时会发出砰砰的声音。

我已经创建了模型、查看了所有内容，但是当我点击或触摸气泡时，我无法播放音频。

struct ImmersiveView: View {
    
    @State var predicate = QueryPredicate<Entity>.has(ModelComponent.self)
    @State private var timer: Timer?
    @State private var audioController: AudioPlaybackController?

    var body: some View {
        RealityView { content in
            // Add the initial RealityKit content
            if let immersiveContentEntity = try? await Entity(named: "Bubble", in: realityKitContentBundle) {
                content.add(immersiveContentEntity)

                // Put skybox here.  See example in World project available at
                // https://developer.apple.com/
            }
        }.gesture(SpatialTapGesture().targetedToEntity(where: predicate).onEnded({
            value in
            let entity = value.entity
            
            let spatialAudio = entity.findEntity(named: "SpatialAudio")
            
            guard let resource = try? AudioFileResource.load(named: "/Bubble/bubble_sound_43207.mp3", from: "Bubble.usda", in: realityKitContentBundle) else {
                fatalError("Unable to find bubble audio file.")
            }
            
            audioController = (spatialAudio?.prepareAudio(resource))!
            audioController?.play()
            
            var material = entity.components[ModelComponent.self]?.materials.first as! ShaderGraphMaterial
            let frameRate: TimeInterval = 1.0/60.0
            let duration: TimeInterval = 0.25
            let targetValue: Float = 1
            let totalFrames = Int(duration / frameRate)
            
            var currentFrame = 0
            var popValue: Float = 0
            
            timer?.invalidate()
            timer = Timer.scheduledTimer(withTimeInterval: frameRate, repeats: true, block: { timer in
                currentFrame += 1
                let progress: Float = Float(currentFrame) / Float(totalFrames)
                
                popValue = progress * targetValue
                
                do {
                    try material.setParameter(name: "Pop", value: .float(popValue))
                    entity.components[ModelComponent.self]?.materials = [material]
                }
                catch {
                    print(error.localizedDescription)
                }
                
                if currentFrame >= totalFrames {
                    timer.invalidate()
                    entity.removeFromParent()
                    
                }
            
            })
        }))
    }
}

我最大的猜测是它找不到音频文件，但我已经尝试了我能想到的所有可能的路径。

我想不出如何共享文件结构，但如果需要的话我可以共享。

请让我知道我搞砸了什么。哈哈。
