Tic Tac Toe Finding Winner

I know I need to use an if statement in order to determine if "x" or "o" is the winner or if there is a tie. At one point I was able to get the screen that shows up to say TIE, but it did it even if x or o went. I really have no idea what could improve the code. Any help is greatly appreciated. import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo) import java.awt.Color;

The decision-making to see if there is a winner or tie should be done in your game-playing world (not in the world that displays who won or not). You do, however, have a String being received by the constructor from the previous world which would be best used to transmit the text that needs displayed. I do not see where the variable 'clicks' is used; though, I can tell you this -- when line 36 executes the value of 'clicks' will be zero (0), to be sure (therefore, the 'TIE' message will never show). But, if you move the decision-making to the game-playing world where the variable 'clicks' is (should be) located, then that will no longer be an issue (in this world).

In my Tic-Tac-Toe world class it determines if there is a winner or not, however not a tie. I took out "clicks" completely from the Winner world class, and now it resumes the tie screen for any type of win. Thank you!

In the Winner world constructor, you probably do not want to check for mouseClicks. Just check the 'letter' that is brought in

String text = "TIE";
if ("o".equals(letter)) text = "Congratulations, O is the WINNER!";
if ("x".equals(letter)) text = "Congratulations, X is the WINNER!";
bg.drawString(text, 300, 200);
to replace lines 26 through 39.

That makes a lot of sense even if I would have never thought of it. Thank you so very very much.
