Random x movement?

Hi eveyone,

I have a question about random movement on X axis.

I need it to bring me both positive and negative numbers??

I’ve tired the random(num); script and it works to make it go right.

My script is

	this._x += speedx + **random(100)**;
	speedy = this._y -= speedy;
	pressing = 0;

What’s the simplest way to get a random number either both a positive number or a negative?

ANy help is greatly appreciated.

Thanks in advanced,
Limitlis :cap:
