Question by ShinyTaco · Jun 24, 2015 at 05:09 AM · rotationtransformquaternionsoundplay

How to Play a Sound Every Time a X,Y,Z Coordinates Change?

Should be pretty simple but can't think of a solution.

I just need to play a short sound everytime an X,Y,Z coordinate changes, preferable every time it increases or decreases by 1.0.

Any suggestions?

Thanks.

Hey there!

Try something like this.. (Warning, untested code)

 Vector3 CurrentPosition;
 public float timeIncrement = 1;
 public AudioClip yourAudioClip;
 
 void Start(){
 CurrentPosition = transform.position;
 StartCoroutine(CheckPosition());
 }
 
 IEnumerator CheckPosition(){
 yield return new WaitForSeconds(timeIncrement);
 float x = transform.position.x;
 float y = transform.position.y;
 float z = transform.position.z;
 
 if(CurrentPosition.x > x + 1 || CurrentPosition.x < x - 1 ||
 (CurrentPosition.y > y + 1 || CurrentPosition.y < y - 1 ||
 (CurrentPosition.z > z + 1 || CurrentPosition.z < z - 1)
 GetComponent<AudioSource>().PlayOneShot(yourAudioClip);
 CurrentPosition = transform.position;
 StartCoroutine(CheckPosition());
 }

The simplest way I can think of is to keep a copy of your position vector and check distance every frame. Something along these lines:

 public class MyClass : MonoBehaviour
 {
     private Vector3 m_pos;
 
     void Start()
     {
         m_pos = transform.position;
     }
 
     void Update()
     {
         if (Vector3.Distance(m_pos, transform.position) >= 1.0f)
             {
                 PlaySound();
             }
 
             m_pos = transform.position;
     }
 }
