Trying to call OnTriggerEnter2D once but being called multiple times...

Questions & Answers
1

I’m new to Unity and I’m trying to get OnTriggerEnter2D(Collider2D col) to work just once when triggered to add to a variable. But when triggered it keep on adding constantly and not stopping when it is not being triggered anymore. Any help would be appreciated!!

This is what what I did for the trigger to be called

// Use this for initialization
void Start () {

}

// Update is called once per frame
void Update () {

}

public void OnTriggerEnter2D(Collider2D col)
{
    targetHit ++;
    Resetting.Reset();
    
}

}

And this is where its going

public MonsterTarget monTarget;

public Text scoreText;
public Text highScoreText;

public float scoreCount;
public float highScoreCount;

public bool scoreIncreasing;

// Use this for initialization
void Start () {
    if(PlayerPrefs.HasKey("HighScore"))
        {
        highScoreCount = PlayerPrefs.GetFloat("HighScore");
    }
}

// Update is called once per frame
void Update () {
    if (scoreIncreasing)
    {
        scoreCount += monTarget.targetHit;//RIGHT HERE
    }

    if (scoreCount > highScoreCount)
    {
        highScoreCount = scoreCount;
        PlayerPrefs.SetFloat("HighScore", highScoreCount);
    }

    scoreText.text = "Score: " + Mathf.Round(scoreCount);
    highScoreText.text = "High Score: " + Mathf.Round(highScoreCount);

}

}

Once the condition in is met

 if (scoreIncreasing)
 {
     scoreCount += monTarget.targetHit;//RIGHT HERE
 }

you will see constantly increasing score, on each frame, as you never seem to reset the condition.

To make what you want, you probably need to make something like this:

 if (scoreIncreasing)
 {
     scoreCount += monTarget.targetHit;
     scoreIncreasing = false; //RIGHT HERE
 }

Hope that helps
