Getting a method to work

I have a method in my world that changes the speed of my actor depending on how many points I have, but I cant get it to work because I need to put the method in my actor first. this is in my world: if(Greenfoot.getRandomNumber(1000) < enemySpawnRate) { Enemy e = new Enemy(); e.setSpeed(enemySpeed); addObject(e, Greenfoot.getRandomNumber(getWidth() - 20)+ 5, -30); scoreboard.addScore(5); } and i need to put setSpeed in my actor. what should the setSpeed method look like?

// in your actor
public void setSpeed(int speed) {

  // do something here

}
this way?

What are you suppose to write in the "//do something here"?

This is what i put but it doesn't work it just adds the enemySpeed to the Y value once and the enemies just stay in one spot and don't continually fall towards the bottom. 
public void setSpeed(int enemySpeed)
	{
		setLocation(getX(), getY()+enemySpeed);
	}

The body you added to the method does not set the speed of the actor (it moves the actor down by the speed given). You need a statement that sets the speed of the actor (assigns the given value to the field that represents the speed of the actor)..
