My game is to get to the goal before your opponent. when you reach the goal first you get one point. every time you get a point everyone respawns where they started. I'm using: 
public void score()
    {
        
        if(isTouching(Goal.class))
        {
            points = points + 1;
            setLocation(1083,20);
        }
    }
to relocate this player, but the other player still stays. HELP.

Please post your current world class code so that it can be confirmed that it is set up properly to do what you are wanting.

        }
}
}
^ here is my world code. What i want is that i can move another player when this player touches the goal.

You cannot tell me that this class compiles okay. Both 'fish' (on line 15) and 'fish2' (on line 17) are not defined anywhere. Maybe they are supposed to be your P1 and P2 objects (created on lines 14 and 16) which are not added into the world anywhere. Since you are basically doing a reset when a player touches a goal, the code to perform it should go in the MyWorld class. You can add the following method to it: 
public void resetPlayers()
{
    P1 player1 = getObjects(Player1.class).get(0);
    player1.setLocation(20, 20);
    P2 player2 = getObjects(Player2.class).get(0);
    player2.setLocation(1080, 20);
}
Now, when a player touches a goal, you can call this 'score' method 
public void score()
{
    if (isTouching(Goal.class))
    {
        points = points+1;
        ((MyWorld)getWorld()).resetPlayers();
    }
}

I have entered in the code, hopefully in the right places but there seem to be a few mistakes, here is my code for my player 1: 
public class P1 extends Actor
{
    private int points = 0;
    /**
     * Act - do whatever the Fish wants to do. This method is called whenever
     * the 'Act' or 'Run' button gets pressed in the environment.
     */
   public void act() 
    {
        gameOver();
        p2score();
        score();
        resetPlayers();
              if (Greenfoot.isKeyDown("S"))
        {
            setLocation(getX(), getY() + 3);
            Actor aWallCell = getOneIntersectingObject(wallRect.class) ; 
            if (aWallCell != null)
                setLocation (getX(), getY() - 3);
        }
        if (Greenfoot.isKeyDown("W"))
        {
            setLocation(getX(), getY() - 3);
            Actor aWallCell = getOneIntersectingObject(wallRect.class) ; 
            if (aWallCell != null)
                setLocation (getX(), getY() + 3);
        }
        if (Greenfoot.isKeyDown("D"))
        {
            setLocation(getX() + 3, getY());
            Actor aWallCell = getOneIntersectingObject(wallRect.class) ; 
            if (aWallCell != null)
                setLocation (getX() - 3, getY());
        }
        if (Greenfoot.isKeyDown("A"))
        {
            setLocation(getX() - 3, getY());
            Actor aWallCell = getOneIntersectingObject(wallRect.class) ; 
            if (aWallCell != null)
                setLocation (getX() + 3, getY());
        }

The 'resetPlayers' method is supposed to be in your MyWorld class.
