I'm a new coder and I've been creating a game where a alien crosses a road and to the other side to get to the mother ship without being hit by a car the problem is that the cars keep overlapping each other and don't know how to fix this. here's the code
public void act() {
       if (Greenfoot.getRandomNumber(100) == 1){
           addObject(new Car(),0,Greenfoot.getRandomNumber(200)+200);
        }
    }
this is in the world class

Add new cars into the world at (0, 0) and use the addedToWorld method in the Car class to place the car so that it is not touching another: 
protected void addedToWorld(World world)
{
    while (getY == 0 || isTouching(Car.class)) setLocation(0, Greenfoot.getRandomNumber(200)+200);
}

What should I add into the (World world) area? My world name is Road and I tried Road, Road.class, and Road(). But, it keeps giving me errors.

You keep it as it is. At least the “World”. You can change “world” to whatever variable name you want. It isn’t used anyway.
