help with a for loop please!

Hey guys, kinda a nooby question with a for loop....
I have 4 objects that I all want to have their own velocities.

I have a bunch of variables (each one has a different value):

PHP Code:

---

public var vx1:Number;
public var vx2:Number;
public var vx3:Number;
public var vx4:Number; 


---

Rather than having a function for each object to say:

PHP Code:

---

function1 { this.x = vx1}
function2 { this.x = vx2}
function3 { this.x = vx3}
function4 { this.x = vx4} 


---

I'd like to have a for loop to have my objects x position to += vx(1 through 4):

PHP Code:

---

for (var i:Number=0; i<5; i++) 
    {
        this.x += (vx+[i]);
        } 


---

So I tried the above with a combination of " " around different parts of (vx+[i]) but I realized that turning any of it into a string means 'this.x' cannot read it because x has to be a number not a string.

So how can I make this.x = vx1 then vx2 and so on with a for loop?

Thanks

use array notation

Code:

---

for( var i : Number = 1 ; i < 4 ; i ++ ) {
        this.x += this["vx" + i];
};

---

And you should have used an actual array for your vxs to begin with.

Code:

---

var vxs:Array = new Array();

---

now you can use the array elements directly in place of your variables. Arrays start at 0 rather than 1.

Code:

---

vxs[0] = 5;
vxs[1] = 4;
vxs[2] = 0;
vxs[3] = -2;

---

Code:

---

for( var i:int = 0 ; i < 4 ; i++ ) {
        this.x += vxs[i];
};
