detecting touch android just once in update
i'm making a whac a mole game and i want the moles to detect a hit only once in a lifetime of 1 second,and if not hit to reduce the number of lives the player has.unfortunately the script is called too many times the first time itself and the user dies even before three moles show up .the deadcount reaches zero in the first mole itself.here's the code
using UnityEngine;
using System.Collections;
public class MoleHit : MonoBehaviour {
// Use this for initialization
public Vector2 touchpos;
public static bool hitFound=false;
public Sprite cracked;
public Sprite intact;
private SpriteRenderer sp;
void Start () {
sp = gameObject.GetComponent<SpriteRenderer> ();
sp.sprite = intact;
}
void FixedUpdate()
{
if(Input.touchCount==1) {
if (Input.GetTouch (0).phase == TouchPhase.Began) {
Vector3 pos = Camera.main.ScreenToWorldPoint (Input.GetTouch (0).position);
touchpos = new Vector2 (pos.x, pos.y);
}
if (collider2D.OverlapPoint (touchpos)) {
sp.sprite = cracked;
hitFound = true;
audio.Play ();
}
}
Debug.Log (hitFound);
Scorer ();
}
void Scorer()
{
if (hitFound) {
ScoreCounter.countScore++;
hitFound=false;
}
else {
ScoreCounter.deadCount--;
}
}
}

I would add a timer and use regular update. AFAIK using fixed update is not recommended when using input.
It would something like this: (untested!)
using UnityEngine;
using System.Collections;
public class MoleHit : MonoBehaviour {
// Use this for initialization
public Vector2 touchpos;
public static bool hitFound=false;
public Sprite cracked;
public Sprite intact;
private SpriteRenderer sp;
public float TimeoutTime = 1.0f;
private float timeCounter;
private bool hitSet;
void Start () {
sp = gameObject.GetComponent<SpriteRenderer> ();
sp.sprite = intact;
touchpos = new Vector2(0.0f,0.0f);
timeCounter = 0.0f;
hitSet = false;
}
void Update()
{
timeCounter += Time.DeltaTime;
if(Input.touchCount==1 && !hitSet)
{
hitSet = true;
if (Input.GetTouch (0).phase == TouchPhase.Began)
{
Vector3 pos = Camera.main.ScreenToWorldPoint (Input.GetTouch (0).position);
touchpos = new Vector2 (pos.x, pos.y);
}
}
if(timeCounter > TimeoutTime)
{
timeCounter = 0.0f;
hitSet = false;
if (collider2D.OverlapPoint (touchpos))
{
sp.sprite = cracked;
hitFound = true;
audio.Play ();
}
Debug.Log (hitFound);
Scorer ();
}
}
void Scorer()
{
if (hitFound) {
ScoreCounter.countScore++;
hitFound=false;
}
else {
ScoreCounter.deadCount--;
}
}
}
