I've been making a game of tic tac tow where you can click to enter your "x" or "o" but am having trouble centering each of them and making the "x" or " o" bigger. This is what I have currently.
TTCboard = zeros(3,3);
% for creating the standard tic-tac-toe board in green
plot([.5 3.5],[-1.5 -1.5], 'g','linewidth',1);% creates top horizontal line in board
plot([2.5 2.5],[-.5 -3.5], 'g','linewidth',1)% creates right-most vertical line
plot([.5 3.5],[-2.5 -2.5], 'g','linewidth',1)% creates bottom horizontal line
plot([1.5 1.5],[-.5 -3.5], 'g','linewidth',1)% creates left-most vertical line
axis off % keeps the X & y-axis off, creating a better looking natural board
hold off% ensures later commands are added to existing board
xticks([0 1 2 3]); yticks([0 1 2 3]);
player = 'X'
fprintf('%s click to place a piece\n', player);
[x, y] = ginput(1);
x = floor(x) + 1/2;
y = floor(y) + 1/2;
text(x, y, player);
Any tips on how to center the x's/o's and make them bigger?
