Unity3d脚本使用丢失时AddComponent参考音频剪辑（） [英] Unity3d script losing AudioClip reference when using AddComponent()

问题描述

我有以下与公共音频剪辑变量脚本（2＃）。当我addComponent，就失去了参考。

I have script (#2) below with a public AudioClip variable. When I 'addComponent', it loses that reference.

我已经测试它手动添加到编辑器中的一个对象，在这种情况下，它的工作原理确定。为什么我的脚本运行过程中添加失去参考？

I've tested manually adding it to an object in the editor, and in that case it works OK. Why does my script added during runtime lose the reference?

游戏对象1：有这个脚本（＃1）连接

GameObject 1: has this script (#1) attached

void HitByRay() {
    clock = GameObject.FindGameObjectWithTag("Clock_Arrow").GetComponent<Clock>();
    clock.gameObject.AddComponent<Tick_Audio_Script>();
}

哪个重视以下脚本（＃2）的时钟对象。

Which attaches the following script (#2) to the 'Clock' object.

public int safetyCounter;
float gapToNext;
public AudioClip tickAudio;

// Use this for initialization
void Start () {
    startTicker(100);
}

void startTicker(int maxTicks)
{
    safetyCounter = maxTicks;
    gapToNext = 1f;
    playTick();

}

void playTick()
{
    Debug.Log("Tick");
    if (gapToNext < 0.1 || safetyCounter == 0)
    {
        Debug.Log("We're done...!");
        return;
    }
// **ERROR HERE CLIP NOT FOUND** 
    AudioSource.PlayClipAtPoint(tickAudio, gameObject.transform.position, 1f);

    gapToNext = gapToNext * 0.97f;
    safetyCounter--;
    Invoke("playTick",gapToNext);
}

下面是在编辑器中，在那里我已经分配音频剪辑的脚本。

Here's the script in the editor, where I've assigned the audioclip.

但是，当它通过AddComponent，参考该剪辑不来通过连接（后我打游戏和'打'的高度重视这个剧本我的触发器对象）？这将导致一个空引用错误，因为没有找到要播放的剪辑

But when it's attached via 'AddComponent', the reference to that clip does not come through (after I hit play and 'hit' my trigger object which attaches this script)? This results in a null reference error as there is no clip found to be played.

我AudioListener（位于不同的物体上）工作，因为有被场景中的正确播放其他声音。

My AudioListener (located on a different object) is working, as there are other sounds being played correctly in the scene.

再次我测试过手动添加这个脚本在它的工作原理编辑任何对象pre-运行。这是为什么？

Again, I've tested adding this script manually to any object pre-run in the editor it works. Why is this?

推荐答案

这有一个简单的解决方案。您可以执行下列操作之一：

This has a simple solution. You can do one of the following:

1）创建一个prefab和所需的引用添加到时钟。

1) Create a prefab and add it to "clock" with the needed references.

2）做到这一点：

void HitByRay() {
    clock = GameObject.FindGameObjectWithTag("Clock_Arrow").GetComponent<Clock>();
    clock.gameObject.AddComponent<Tick_Audio_Script>();
//NEW PART
    clock.gameObject.GetComponent<Tick_Audio_Script>().TickAudio = (desired Audio);
}

希望这有助于。
