I posted a thread and I’ve partly worked out how to do what I need but I still need a slight push in the right direction.

I’ve got two movieclips box and box2 and I’ve place them in the same layer because I couldn’t get each box to move individually in seperate ones I’ve placed this code on the frame

startx = box.\_x;  
starty = box.\_y;  
startx = box2.\_x;  
starty = box2.\_y;  
MovieClip.prototype.shakeYourBody = function(radius) {  
forceX = 2\*(Math.random()-.5)_radius;  
forceY = 2_(Math.random()-.5)_radius;  
this.\_x = startx+forceX;  
this.\_y = starty+forceY;  
};  
this.onEnterFrame = function() {  
// Find distance  
var dx = \_xmouse-box.\_x;  
var dy = \_ymouse-box.\_y;  
var dx = \_xmouse-box2.\_x;  
var dy = \_ymouse-box2.\_y;  
var distance = dx_dx+dy\*dy;  
box.shakeYourBody(10000/(distance+1000));  
box2.shakeYourBody(10000/(distance+1000));  
};

Now I’ve got both movieclips shaking but they’re on top of each other rather than in the places I want them. I’m sure its a case of changing something but what?

have a go

Cheers!

It’s the first four lines! You are assiging the value of box.\_x to startx and the box.\_y to starty and then you are assining them again but foer the other box!  
Just make it  
startx = box.\_x  
starty = box.\_y  
startx2 = box2.\_x  
startx2 = box2.\_y

but there’s something strange going on there! hwo can you place that first code on a frame if there are lines which start with “this.”.  
there shoud be scripts on both of the boxes… :-\

Nope, the problem is that you overwrite dx and dy.

```auto
this.onEnterFrame = function() {
  // Find distance
  var dx = _xmouse-box._x;
  var dy = _ymouse-box._y;
  var distance = dx*dx+dy*dy;
  box.shakeYourBody(10000/(distance+1000));

  var dx = _xmouse-box2._x;
  var dy = _ymouse-box2._y;
  var distance = dx*dx+dy*dy;
  box.shakeYourBody(10000/(distance+1000));
  box2.shakeYourBody(10000/(distance+1000));
};

```

Syko\>\> What’s wrong with this on a frame?

I’ve changed the script to this as ilyaslamasse posted but the two boxs are still on top of each other when I publish the movie…even thought they are on the other side of the screen to eachother.

startx = box.\_x;  
starty = box.\_y;  
startx = box2.\_x;  
starty = box2.\_y;  
MovieClip.prototype.shakeYourBody = function(radius) {  
forceX = 2\*(Math.random()-.5)_radius;  
forceY = 2_(Math.random()-.5)_radius;  
this.\_x = startx+forceX;  
this.\_y = starty+forceY;  
};  
this.onEnterFrame = function() {  
// Find distance  
var dx = \_xmouse-box.\_x;  
var dy = \_ymouse-box.\_y;  
var distance = dx_dx+dy_dy;  
box.shakeYourBody(10000/(distance+1000));  
var dx = \_xmouse-box2.\_x;  
var dy = \_ymouse-box2.\_y;  
var distance = dx_dx+dy\*dy;  
box2.shakeYourBody(10000/(distance+1000));  
};

True, I didn’t notice that you had overwritten startx and starty too. Gimme a second.

```auto
box.startx = box._x;
box.starty = box._y;
box2.startx = box2._x;
box2.starty = box2._y;
MovieClip.prototype.shakeYourBody = function(radius) {
	forceX = 2*(Math.random()-.5)*radius;
	forceY = 2*(Math.random()-.5)*radius;
	this._x = this.startx+forceX;
	this._y = this.starty+forceY;
};
this.onEnterFrame = function() {
	// Find distance
	var dx = _xmouse-box._x;
	var dy = _ymouse-box._y;
	var distance = dx*dx+dy*dy;
	box.shakeYourBody(10000/(distance+1000));
	var dx = _xmouse-box2._x;
	var dy = _ymouse-box2._y;
	var distance = dx*dx+dy*dy;
	box2.shakeYourBody(10000/(distance+1000));
};

```

I put startx and starty as a property of the boxes.

pom 🙂
