我很努力地让我的SoundEngine类的函数PlaySound在我想要的地方播放。从SoundEngine类的任意对象运行一个方法
功能需要一个全球性的功能，但作为功能指的是SoundEngine使对象我不能让静态的。
我将展示的一些重要片段：
在游戏世界里我类：
using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Graphics;
using Microsoft.Xna.Framework.Content;
using Microsoft.Xna.Framework.Media;
using Microsoft.Xna.Framework.Audio;
using Microsoft.Xna.Framework.Input;
using System;
using SoundEngineSpace;
public GameWorld(int width, int height, ContentManager Content)
{
screenWidth = width;
screenHeight = height;
random = new Random();
gameState = GameState.Playing;
block = Content.Load<Texture2D>("block");
font = Content.Load<SpriteFont>("SpelFont");
SoundEffect blockFallSE = Content.Load<SoundEffect>("BlockFallSE");
Song BuildingWallsintheCold = Content.Load<Song>("91 Building Walls in the Cold");
soundEngine = new SoundEngine();
soundEngine.addSound(blockFallSE);
soundEngine.addSong(BuildingWallsintheCold);
soundEngine.SetSoundVolume(20);
soundEngine.SetSongVolume(5);
soundEngine.PlaySong(0);
grid = new TetrisGrid(block);
}
在我TetrisGrid类
using System;
using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Graphics;
using Microsoft.Xna.Framework.Input;
using SoundEngineSpace;
...
public void TetNaarBeneden()
{
soundEngine.PlaySound(0);
InPlayGrid.Velocity = new Vector2(0, gridblock.Height);
CheckValidLocation();
}//Moves tet down
和声音发动机类：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Audio;
using Microsoft.Xna.Framework.Media;
namespace SoundEngineSpace
{
public class SoundEngine
{
private void soundEngine()
{
}
BackgroundSound backgroundSound = new BackgroundSound();
SoundEffects soundEffects = new SoundEffects();
public void addSong(Song s)
{
backgroundSound.AddBackgroundSound(s);
}
public void addSound(SoundEffect s)
{
soundEffects.AddSound(s);
}
public void PlaySong(int s)
{
backgroundSound.PlayBackgroundSound(s);
}
public void PlaySound(int s)
{
soundEffects.PlaySound(s);
}
public void SetSongVolume(int v)
{
backgroundSound.SetBackGroundSoundVolume(v);
}
public void SetSoundVolume(int v)
{
soundEffects.SetSoundEffectVolume(v);
}
}
}
class BackgroundSound
{
public static void backGroundSound()
{
}
private List<Song> BackgroundSoundEffects = new List<Song>();
private bool PlayingBackGroundSound = false;
public void AddBackgroundSound(Song s)//addsongs to the list
{
BackgroundSoundEffects.Add(s);
}
public void PlayBackgroundSound(int s)//plays BackgroundSound based on location in the list
{
MediaPlayer.IsRepeating = true;//If I use this exact soundengine again, move this to it's own function instead!
if (BackgroundSoundEffects.Count() > s)
{
if (PlayingBackGroundSound)
MediaPlayer.Stop();
MediaPlayer.Play(BackgroundSoundEffects.ElementAt(s));
PlayingBackGroundSound = true;
}
else
{
Console.WriteLine("Couldent find the BackgroundSound");
}
}
public void SetBackGroundSoundVolume(int v)
{
MediaPlayer.Volume = (float)v/100;
}
}
class SoundEffects
{
public static void soundeffects()
{
}
private List<SoundEffect> soundEffects = new List<SoundEffect>();
public void AddSound(SoundEffect s)//addsongs to the list
{
soundEffects.Add(s);
}
public void PlaySound(int s)//plays sound based on location in the list
{
if (soundEffects.Count() > s)
{
SoundEffect ToPlaySound = soundEffects.ElementAt(s);
ToPlaySound.Play();
}
else
{
Console.WriteLine("Couldent find the sound");
}
}
public void SetSoundEffectVolume(int v)
{
SoundEffect.MasterVolume = (float)v/100;
}
}
