distance bar

Scripting
1

Hey, im trying to make a bar which will show how far are you from the end im not sure how to do it… kinda stuck.
i got how to see the distance bitween 2 objects and how to make the progress bar but to make them fit each other is where i got stuck :?

var other : Transform;
var barDisplay : float = 0;
var pos : Vector2 = new Vector2(20,40);
var size : Vector2 = new Vector2(60,20);
var progressBarEmpty : Texture2D;
var progressBarFull : Texture2D;

function OnGUI()
{

    // draw the background:
    GUI.BeginGroup (new Rect (pos.x, pos.y, size.x, size.y));
        GUI.Box (Rect (0,0, size.x, size.y),progressBarEmpty);

        // draw the filled-in part:
        GUI.BeginGroup (new Rect (0, 0, size.x * barDisplay, size.y));
            GUI.Box (Rect (0,0, size.x, size.y),progressBarFull);
        GUI.EndGroup ();

    GUI.EndGroup ();

} 

function Update()
{
    var dist = Vector3.Distance(other.position, transform.position);
    print ("Distance to other: " + dist);
    // for this example, the bar display is linked to the current time,
    // however you would set this value based on your desired display
    // eg, the loading progress, the player's health, or whatever.

barDisplay = dist;
}

and yeah i know the last line is not good thats what im trying to fix tho.

if the world is linear (aka you can start at 0 and work to 100% of the level) then you want to take the % of the distance that is done, and fill the bar that way

aka

barDisplay = dist/totalDist;

thanks for the replay but i get an error that it doesnt know what is total dist, should it be a variable?
sorry cause im bad at scripting… :cry:

you need to calculate the total distance for someone to travel the level - aka the distance between the starting point and the ending point

then you save that variable as totalDistance

then by taking dist/totalDistance - you get the % of the level that you have completed

after that when you times that % by the x value in your GUI element, you will get a bar that fills based on % done with the level

sorry for being annoying.
i dont really know how to do that, im just a beginner.
the scene is in side scrolling so you can go both x and -x and jump.
so if i make 2 gameObjects 1 for start and one for the ending, how i will make the distance between thos into percent?
thanks.

i think this should do it

var other : Transform; 
var barDisplay : float = 0; 
var pos : Vector2 = new Vector2(20,40); 
var size : Vector2 = new Vector2(60,20); 
var progressBarEmpty : Texture2D; 
var progressBarFull : Texture2D; 
var totalDistance : float = 0;

var startPoint : GameObject;
var endPoint : GameObject;

var Start(){
totalDistance = Math.Abs(endPoint.transform.position.x - startPoint.transform.position.x);
}

function OnGUI() 
{ 

    // draw the background: 
    GUI.BeginGroup (new Rect (pos.x, pos.y, size.x, size.y)); 
        GUI.Box (Rect (0,0, size.x, size.y),progressBarEmpty); 

        // draw the filled-in part: 
        GUI.BeginGroup (new Rect (0, 0, size.x * barDisplay, size.y)); 
            GUI.Box (Rect (0,0, size.x, size.y),progressBarFull); 
        GUI.EndGroup (); 

    GUI.EndGroup (); 

} 

function Update() 
{ 
    var dist = Vector3.Distance(other.position, transform.position); 
    print ("Distance to other: " + dist); 
    // for this example, the bar display is linked to the current time, 
    // however you would set this value based on your desired display 
    // eg, the loading progress, the player's health, or whatever. 

barDisplay = dist/totalDistance; 
}

your awesome for these replays but unfortuantly it doesnt works right :cry:
its backwards and it starts from 1.6 even tho im in the same place as the start point.
but thanks for leading me closer you rock!

8

its backwards because you have

var dist = Vector3.Distance(other.position, transform.position);

and you want

var dist = Vector3.Distance(transform.position, other.position);

also - is other the end point??? if so you can change this line to

totalDistance = Math.Abs(other.position.x - startPoint.transform.position.x);

and one more change :

barDisplay = (totalDistance - dist)/totalDistance;

Well i have fixed it now but it goes from 100% to 0% is there any way to make it opposite?

10 
        GUI.BeginGroup (new Rect (0, 0, size.x * (1-barDisplay), size.y));

thanks works now :wink:
