# How to stop a random motion

Hi there,

I followed one of the random motion tutorials from Kirupa. i have a small word made of 10x10 black squares. When someone clicks the word, all the squares start moving around randomly.

What I want to do now is when someone clicks on a moving square, all the squares move back to a given position (obviously, they stop moving randomly).

Is this possible? This is the code I’m using:

``````onClipEvent (load) {
//data you may want to change
width = 500;
height = 400;
speed = Math.round(Math.random()*1)+1;

}
onClipEvent (enterFrame) {
//x movement
if (x_new>this._x) {
sign_x = 1;
} else {
sign_x = -1;
}
dx = Math.abs(x_new-this._x);
if ((dx>speed) || (dx<-speed)) {
this._x += sign_x*speed;
} else {
x_new = Math.random()*width;
}
//y movement
if (y_new>this._y) {
sign_y = 1;
} else {
sign_y = -1;
}
dy = Math.abs(y_new-this._y);
if ((dy>speed) || (dy<-speed)) {
this._y += sign_y*speed;
} else {
y_new = Math.random()*height;
}
}

``````

I know that I should have it has a function, but I don’t even know how to make this bit of code in a function :tired:

Any help would be greatly appreciated.
