Print whenever variable receives a certain value

Question

I am developing a simple game in which whenever an object exits the screen a variable of name score gets +1.

The idea is simple, what I am trying to do is to print the value of the variable score whenever the player scores 10 new points, that is, whenever the variable score receives the value of itself +10 is printed the value of the variable.

To do this I declared a variable called x that receives the same score value, if x equals 10 the score value is printed. Once the score value is printed, x returns to 0, and the idea is to repeat this over and over again.

The problem is that after printing score and the variable x is reset, x will receive the score value again and nothing will be printed on the screen anymore, as x will not be receiving 0 at all.

How can I fix this? I hope I’ve been clear!

CODE

Object:

public int x;

void Start() {

}

void Update() {

}

void OnBecameInvisible() {
    Score.score += 1;
    x = Score.score;

    if (x == 10)
    {
        Debug.Log("VALOR DE SCORE: " + Score.score);
        x = 0;
    }
}

Score:

public static int score;
public Text score_txt;

void Start() {
    score = 0;
}

void Update () {
    score_txt.text = score.ToString();
}

Answer 1

Do not need the variable x, just need to validate whether the rest of the entire division by 10 is 0:

void OnBecameInvisible() 
{
    Score.score += 1;

    if ((Score.score % 10) == 0)
        Debug.Log("VALOR DE SCORE: " + Score.score);
}
