object destroy and scoring points

Questions & Answers
1

i've looked through questions already but i cant seems to find a specific answer/script to my problem. im making a ball rolling game which destroys objects in turn giving you a score. i have 2 scripts at the min:

static var score : float = 0;

function Update () {
    guiText.text = "Score : " + score;

}

this shows "score:" on the screen and my other script is:

function OnCollisionEnter ( collision : Collision){
    if (collision.gameObject.tag == "DestructibleObject")
    KeepScore.score++;

}

which is attatched to my player (rolling ball) and updates the "score:" by 1 everytime i hit an object named "DestructibleObject". the problem is that the score keeps increasing, im wanting to limit the score to 1 for each object. it would be even better if anyone can tell me how to destroy the object at the same time. i added the line:

Destroy (collision.gameObject);

so the script looks like:

function OnCollisionEnter ( collision : Collision){

    if (collision.gameObject.tag == "DestructibleObject")
    KeepScore.score++;
    Destroy (collision.gameObject);

}

but when i load the level the terrain is getting destroyed (i think when my ball thouches it to start with). if i remove the keepScore.score++; line i can go round the level fine (it doesn't get destroyed) and when i hit an object it is destroyed. when the 2 lines of script are together it just doesn't want to work : /

any help is highly appreciated

thanks.

I believe the problem is with your if statement syntax. It's always best to surround the code after the if with curly braces. So in your code:

    var oneTime : boolean = false;

    function OnCollisionEnter ( collision : Collision){
        if(!oneTime){
        if (collision.gameObject.tag == "DestructibleObject"){
        KeepScore.score++;
        oneTime = true;
        }
    }
    }

Everything in the curly brackets gets called if the if-statement is satisfied
