Simple Script - and no result

Questions & Answers

Can someone tell me what I have done wrong? This is a simple script that should open and close a double door after pushing a button on a wall.

When I test it I get "b" in the debug but not "a" - so the doors close but don't open again (also note the doors were closed to start with)

var door_left : Transform;

var door_right : Transform;

var door_left_startX : float; var door_right_startX : float;

var countA : float = 0; var door : boolean = true;

function Update () { var hit : RaycastHit;

//find forward then test for x meters in front of position
if (Physics.Raycast (transform.position, transform.forward, hit, 2))    
{
    if(hit.collider.gameObject.tag=="Player" && Input.GetAxis ("e_key") )
    {

        if (door == true && countA == 0)
        {
            countA = -1;
            door = false;
            print ( "a");
        }

        if (door == false && countA == 0)
        {
            countA = 1;
            door = true;
            print ( "b");
        }   
    }
}

if (countA > 0)
{
    countA = countA - 0.01;
}

if (countA < 0)
{
    countA = countA + 0.01;
}

door_left.transform.position = Vector3(door_left_startX+(countA*-1), door_left.transform.position.y, door_left.transform.position.z);
door_right.transform.position = Vector3(door_right_startX+countA, door_right.transform.position.y, door_right.transform.position.z);

}

Hi, try to use this:

function Update() {
    var hit : RaycastHit;
    if (Physics.Raycast (transform.position, transform.forward, hit, 2)) {
        if(hit.collider.gameObject.tag == "Player" && /* The button action is activated */) {
            if (door == true) { // Opend the doors
                countA += 0.01;
            }   
        }
    }

    if (countA == 1) { // The doors are totally open
        door = false;
    }

    if (countA > 0 && door == false) { // Close the doors
        countA -= 0.01;
    }
    door_Left.localPosition = Vector3(-countA, 0, 0);
    door_Right.localPosition = Vector3(countA, 0, 0);

}

This should work, when work with two objects (one in front another) just type value and -value to set positive and negative motion, the recommendation it's to use always positive number so this can be made negative using the "-" before the value, if you use the boolean state in a "if" statement with the same boolean as a condition this will interrupt if condition and the loop will be interrupted.

Hopes this help.

Finally it works! - wouldn't have figured it out if you hadn't told me about the Boolean thingy though.

Thanks for your help!

Here is the final code:

var door_left : Transform;

var door_right : Transform;

var door_left_startX : float; var door_right_startX : float;

var countA : float = 0; var opening : int = 0;

function Update () { var hit : RaycastHit;

//find forward then test for x meters in front of position
if (Physics.Raycast (transform.position, transform.forward, hit, 2))    
{
    if(hit.collider.gameObject.tag=="Player" && Input.GetAxis ("e_key") )
    {           
        if (countA <= 0)
        {
            opening = -1;
        }
        if (countA >= 1)
        {
            opening = 1;
        }   
    }
}

if (opening == 1 && countA > 0)
{
    countA = countA - 0.01;
}

if (opening == -1 && countA < 1)
{
    countA = countA + 0.01;
}

door_left.transform.position = Vector3(door_left_startX+(countA*-1), door_left.transform.position.y, door_left.transform.position.z);
door_right.transform.position = Vector3(door_right_startX+countA, door_right.transform.position.y, door_right.transform.position.z);

}
