对象引用才能访问非静态成员 [英] An object reference is required to access a non-static member

问题描述

我在这个错误来了，我不知道为什么......我想看看它，人们都在说创建类的一个对象或创建方法为静态...但我不能确定如何。

下面是我下面的code：

 公共类SoundManager类：MonoBehaviour {

公开名单＆LT; AudioSource＆GT; audioSounds =新的名单，其中，AudioSource＆GT;（）;
公共双minTime = 0.5;

公共静态无效playSound（音频剪辑sourceSound，Vector3类型objectPosition，INT卷，浮audioPitch，INT dopplerLevel）
{
    布尔playsound = FALSE;
    通过列表的foreach的foreach（AudioSource声音audioSounds）//循环
    {
        如果（sourceSound.name = sound.name和放大器;！＆安培; sound.time＆LT; = minTime）
        {
            playsound = TRUE;
        }
    }

    如果（playsound）{
        AudioSource.PlayClipAtPoint（sourceSound，objectPosition）;
    }
}
}
 

解决方案

您应该让您的audioSounds和minTime成员静态：

 公共静态列表＆LT; AudioSource＆GT; audioSounds =新的名单，其中，AudioSource＆GT;（）;
公共静态双minTime = 0.5;
 

不过，我会考虑使用单一对象，而不是静态的成员，而不是：

 公共类SoundManager类：MonoBehaviour
{

    公开名单＆LT; AudioSource＆GT; audioSounds =新的名单，其中，AudioSource＆GT;（）;
    公共双minTime = 0.5;

    公共静态SoundManager类实例{获得;私定; }

    清醒无效（）
    {
        实例=这一点;
    }

    公共无效playSound（音频剪辑sourceSound，Vector3类型objectPosition，INT卷，浮audioPitch，INT dopplerLevel）
    {
        布尔playsound = FALSE;
        通过列表的foreach的foreach（AudioSource声音audioSounds）//循环
        {
            如果（sourceSound.name = sound.name和放大器;！＆安培; sound.time＆LT; = minTime）
            {
                playsound = TRUE;
            }
        }

        如果（playsound）{
            AudioSource.PlayClipAtPoint（sourceSound，objectPosition）;
        }

    }
}
 

I'm having this error come up and I'm not sure why... I've tried to look it up, people are saying to create an object of the class or create the methods as static... but I'm unsure how.

Here's my code below:

public class SoundManager : MonoBehaviour {

public List<AudioSource> audioSounds = new List<AudioSource>();
public double minTime = 0.5;

public static void playSound(AudioClip sourceSound, Vector3 objectPosition, int volume, float audioPitch, int dopplerLevel)
{
    bool playsound = false;
    foreach (AudioSource sound in audioSounds) // Loop through List with foreach
    {
        if (sourceSound.name != sound.name && sound.time <= minTime)
        {
            playsound = true;
        }
    }

    if(playsound) {
        AudioSource.PlayClipAtPoint(sourceSound, objectPosition);
    }
}
}

解决方案

You should make your audioSounds and minTime members static:

public static List<AudioSource> audioSounds = new List<AudioSource>();
public static double minTime = 0.5;

But I would consider using singleton objects instead of static members instead:

public class SoundManager : MonoBehaviour
{

    public List<AudioSource> audioSounds = new List<AudioSource>();
    public double minTime = 0.5;

    public static SoundManager Instance { get; private set; }

    void Awake()
    {
        Instance = this;
    }

    public void playSound(AudioClip sourceSound, Vector3 objectPosition, int volume, float audioPitch, int dopplerLevel)
    {    
        bool playsound = false;
        foreach (AudioSource sound in audioSounds) // Loop through List with foreach
        {  
            if (sourceSound.name != sound.name && sound.time <= minTime)
            {
                playsound = true;
            }
        }

        if(playsound) {
            AudioSource.PlayClipAtPoint(sourceSound, objectPosition);
        }

    }
}
