Tic Tac Toe Help - Drawing X's and O's

[S_Grimm]

Ok, i'm working on a little tic tac toe game during spare, and i need to draw the x's and o's. i don't want to use a pile of if\else statements, but will if nessesarry. more or less, i would like to be able to click the "square" and have the x or o drawn there. Any ideas?
Thanks in advance

Something like this?

code:

View.Set ('offscreenonly') var x1, y1, x2, y2: int var x_mouse, y_mouse, button, buttonupdown: int x1 := 100 x2 := 200 y1 := 100 y2 := 200 Draw.Box (x1, y1, x2, y2, black) loop     Mouse.Where (x_mouse, y_mouse, button) % or mousewhere     if (button = 1) then         Mouse.ButtonWait ("up", x_mouse, y_mouse, button, buttonupdown)         Draw.Line (x1, y1, x2, y2, red)         Draw.Line (x2, y1, x1, y2, red)         View.Update     end if end loop

something like it. but it needs to have a count so that i can check for win.

You need a 2-d array to keep track of what square has been claimed by which team. Then you use a combination of for loops an if statements to check if someone has won.

[S_Grimm]

so and loop if square one and square 2 and square 3 are claimed by x then end loop sort of style?

[Insectoid]

Uh, its a bit more complicated than that...

I suggest looking someone else's tic-tac-toe. (don't use mine, it's unreadable )

This is how I would end up doing it

If a player goes in a sqaure, set the BoxArray for that square to 1 or 2 depending on the player then have a check

BoxArray (1 to 9)
PlayerCheck

1 is for X
2 is for O

Game Grid
1 2 3
4 5 6
7 8 9

Turing:

%Short example. Basically have every possible way to win in the if statement for XYZ : 1..2 PlayerCheck := XYZ if (BoxArray(1) = PlayerCheck and BoxArray(2) = PlayerCheck and BoxArray(3) = PlayerCheck) or (BoxArray(1) = PlayerCheck and BoxArray(5) = PlayerCheck and BoxArray(9) = PlayerCheck) then XWin := true else end if end for

I'm fairly sure you need some brackets in that if statement, though I may be wrong.

I did

Quote:

(BoxArray(1) = PlayerCheck and BoxArray(2) = PlayerCheck and BoxArray(3) = PlayerCheck) or (BoxArray(1) = PlayerCheck and BoxArray(5) = PlayerCheck and BoxArray(9) = PlayerCheck)

Woops, stupid me. Didn't even see it.

Warchamp, what's the point of this line of code?

code:

PlayerCheck := XYZ

And it's much better just to check to see if all the elements are equal to each other, less comparisons. Using your variables:

code:

if (BoxArray(1) = BoxArray(2) and BoxArray(2) = BoxArray(3)) or (BoxArray(1) = BoxArray(5) and BoxArray(5) = BoxArray(9)) then

For the player check, it's just a quick for loop to check player 1 and player 2 with one group of code

As for your method, a nice idea

[S_Grimm]

ok thanks guys. I think that gitoxa has the right idea. Now, the only way that i can draw an x or o inside the grid when a mouse button is clicked is to use Mouse.Where and a series of if statements, right?
Here's The Example:
If mousex >= 0 and mousex <= 150 and mousey >= 0 and mousey <= 150 and mousebutton = 1 then
draw x
else .
end if

[gitoxa]

Warchamp, I just meant there's no point in assigning a variable to equal XYZ when you can just use XYZ instead.

And A/V, that's one way to do it. The way I did it wa I used a 2d array for the squares, and div'd the MouseX and MouseY values by the size of the squares (with some other manipulation just to give me the right numbers). That ways probably a little more difficult to incoporate correctly, but it allowed to reduce it down to one if statement, and two number manipulations.

ok thanks guys.
