mouse scrolling problem

[ludob]

Hi a friend told me to have a look at his website.
he has galleriess that move left or right depending on the place your mouse is.
he asked me to add a picture in the gallery which i did.
but then it jumps every time it loops.

here is the bit of code that makes it move left i know how the-3192.15 was found but i dont know were they got 49 from

function moveLeft(nPixels) {
this._x -= nPixels;
if (this._x < -3192.15) {
this._x = 49;

could anyone try help me understand thx

Well...

if this is lower than -3192.15 on the stage then it will reset it back to the right via saying this._x = 49.

Do you have a .swf or something you can show us so we can better work out the issue?

Hi,

here is the whole code from one of the pages with a gallery hope this helps...

onClipEvent(load) {

//this._alpha = 0;


//nScreenWidth = 1000;
nMaxRate = 5;
// nPixels determines the speed of the slider movement
function moveLeft(nPixels) {
this._x -= nPixels;
if (this._x < -3566) {
this._x = 5027;
}
}
function moveRight(nPixels) {
this._x += nPixels;
if (this._x > 5027) {
this._x = -3566;
}
}
}


onClipEvent(enterFrame) {

//if (this._alpha < 100) {
//this._alpha += 3;
//}

// move slider with speed dependent on mouse position
if (_root._xmouse < Stage.width/2 && _root._xmouse > 0) {
moveRight(nMaxRate - _root._xmouse * nMaxRate/(Stage.width/2));
} else {
if (_root._xmouse > Stage.width/2 && _root._xmouse < Stage.width) {
moveLeft(_root._xmouse * nMaxRate/(Stage.width/2) - nMaxRate);
}
}
}





the movie clip that holds all the photo's width and height is 17126 pixels by 200 pixels high

the movie clips x position and y position is 3566x and 0y

now this code works perfectly fine but as soon as i add a picture to the movie clip so it can scroll it it jumps every time it loops...

i know that this value in the code ="-3566" is the x position of the movie clip
but how did they get this value ="5027" in the code?

Referencing the clip on which the code is placed...
The clip is 17186 pixels wide and _x position is 3566. Guessing that this clip contains to identical instances of the content. Where each of the instances is 8593 pixels wide. Instance A has it's right side lined up with the center point of the clip and instance B has it's left side lined up with the center point of the clip. So, _x positions are -8593 and 0, respectively.

17186 divide by 2 = 8593

8593 minus 3566 = 5027

Thanks everyone. I understand the process to get the number. The programer that originally coded the pages did it approximately. So I was getting wrong numbers on every different page.
