GetSpectrumData() and Instantiate()

The script I wrote from scratch and work
But it creates too many objects to one beat of music
It should create one object to a single beat
How can I do that?

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class Enginev2 : MonoBehaviour
5. {
6.     //ZMIENNE
7.     //Obiekt
8.     public GameObject objectPrefab;
9.     //treshold
10.     public float spawnThreshold = 0.05f;
11.     //Frequency
12.     public int frequency = 0;
13.     //Window
14.     public FFTWindow fftWindow;
15.  
16.  
17.     //ZMIENNA ILOSC SAMPLI
18.     private float[] samples = new float[4096]; //MUST BE A POWER OF TWO
19.  
20.     void Start()
21.     {
22.  
23.     }
24.  
25.     // Update is called once per frame
26.     void Update ()
27.     {
28.         //GETSPECTRUMDATA
29.         AudioListener.GetSpectrumData(samples, 0, fftWindow);
30.  
31.         //Tworzenie Obiektu
32.         if(samples[frequency] > spawnThreshold)
33.         {
34.             Instantiate(objectPrefab, new Vector3(Random.Range(-10.0f, 10.0f), 5, 0), Quaternion.identity);
35.         }
36.     }
37. }
38.

you could do something like this.

Code (CSharp):

1.  
2. GameObject clone;
3.  
4.  if(samples[frequency] > spawnThreshold  && clone == null)
5.         {
6.             clone = (GameObject)Instantiate(objectPrefab, new Vector3(Random.Range(-10.0f, 10.0f), 5, 0), Quaternion.identity);
7.         }
8. else
9.     clone = null;

 

Not working for me ;c

 

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class Example : MonoBehaviour {
5.  
6.  
7.     //ZMIENNE
8.     //Obiekt
9.     public GameObject objectPrefab;
10.     //treshold
11.     public float spawnThreshold = 0.05f;
12.     //Frequency
13.     public int frequency;
14.     //Window
15.     public FFTWindow fftWindow;
16.  
17.     GameObject clone;
18.    
19.     //ZMIENNA ILOSC SAMPLI
20.     private float[] samples = new float[4096]; //MUST BE A POWER OF TWO
21.    
22.     void Start()
23.     {
24.        
25.     }
26.    
27.     // Update is called once per frame
28.     void Update ()
29.     {
30.         //GETSPECTRUMDATA
31.         AudioListener.GetSpectrumData(samples, 0, fftWindow);
32.         //Tworzenie Obiektu
33.         if(samples[frequency] > spawnThreshold)// && clone != null)
34.         {
35.             clone = (GameObject)Instantiate(objectPrefab, new Vector3(Random.Range(-10.0f, 10.0f), 5, 0), Quaternion.identity);
36.         }
37.         else
38.             clone = null;
39.     }
40.  
41.  
42. }
43.  

make sure your objectPrefab is valid. this error is not a code error is an error concerning the object you want to instantiate

 

Everything its ok. Prefab looks good.

 

the code i posted above is tested and worked fine for me. if you get the error: the thing you want to instantiate is null. usually means your prefab is broken.
or do you mean everything is ok as in it all works fine now?
