Problems implementing two different AS

[Swashbuckler200]

Hi all

I want to implement two AS scripts at a certain point on my timeline however whilst each individual AS works fine, when I combine the two together one cancels out the other.

The first AS slides each individual menu items when the mouse cursor is over them.

//Global Variables
_global.speed = 1.3;
_global.stickiness = 8;
_global.baseX = 5;
_global.finalX = 30;
//Movement Functions
function moveOut ()
{
    this.xStep = 0;
    this.onEnterFrame = function ()
    {
        if (this._x < finalX)
        {
            difference = finalX - this._x;
            this.xStep = (this.xStep + difference * speed) / stickiness;
            this._x += this.xStep;
        }
        if (this._x > finalX)
        {
            this._x = finalX;
        }
    };
}
function moveIn ()
{
    this.xStep = 0;
    this.onEnterFrame = function ()
    {
        if (this._x > baseX)
        {
            difference = finalX - this._x;
            this.xStep = (this.xStep + difference * speed) / stickiness;
            this._x -= this.xStep;
        }
        if (this._x < baseX)
        {
            this._x = baseX;
        }
    };
}
//Assign event handlers
vNav001.onRollOver = moveOut;
vNav001.onRollOut = moveIn;
vNav002.onRollOver = moveOut;
vNav002.onRollOut = moveIn;
vNav003.onRollOver = moveOut;
vNav003.onRollOut = moveIn;

The second AS randomly moves a mc (spiral) around the stage whenever the cursor mouse is over a menu item.

for (i=0; i<4; i++) {
    _root["vNav00"+i].onRollOver = function() {
        _root.spiral_mc._x = random(Stage.width);
        _root.spiral_mc._y = random(Stage.height);
        onEnterFrame = function () {
            _root.spiral_mc._alpha += 5;
        };
    };
    _root["vNav001"+i].onRollOut = function() {
        onEnterFrame = function () {
            _root.spiral_mc._alpha -= 5;
        };
    };
}

Problem is if I combine the two in the order above the menu action script (e.g. the first one) no longer functions.

Any idea how I can solve this problem?

The problem is that you assign a onRollOver event handler to the buttons twice, so the second assignment overwrites the first one.
A possible solution could be to write

vNav001.moveOut = moveOut;

instead of

vNav001.onRollOver = moveOut;

and then in the second piece of code

_root["vNav00"+i].onRollOver = function() {
          [U]this.moveOut()[/U]
          _root.spiral_mc._x = random(Stage.width);
          _root.spiral_mc._y = random(Stage.height);
          onEnterFrame = function () {
               _root.spiral_mc._alpha += 5;
          };
     };

and then do the same for moveIn and onRollOut

BTW you should check out variable scoping, it's very important that you understand what the scope of a variable is, look up "var" and the topic "variable scoping" in the flash helpfiles

Many thanks...it worked a treat.

I will look into variable scoping in my text books as it looks as if can save a lot of time.

Oh, that's not about saving time, it's simply essential
... and agreed it will save you some "pulling out my hair because this *$£µ% thing doesn't do what i want"-time
