How to Make Tic Tac Toe



For this tutorial you need 12 Buttons, 2 Labels, and a timer :

Set the timer property Enable to True then change its interval to 1

Set the labels Visible property to False

Add the controls to the form like the following picture:



Then we start adding the codes:

First we add the following right after Public Class Form1:


Code:
Dim random As String = 1
We add the code for the timer: (The timer is used to generate a random number)

Code:
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick

random += 1

If random = 10 Then

random = 1

End If

End Sub
We add the following code so computer makes the move:

Code:
Public Sub PC()
If random = 1 And Button1.Enabled = True Then
Button1.Text = "O"
Button1.Enabled = False
End If
If random = 2 And Button2.Enabled = True Then
Button2.Text = "O"
Button2.Enabled = False
End If
If random = 3 And Button3.Enabled = True Then
Button3.Text = "O"
Button3.Enabled = False
End If
If random = 4 And Button4.Enabled = True Then
Button4.Text = "O"
Button4.Enabled = False
End If
If random = 5 And Button5.Enabled = True Then
Button5.Text = "O"
Button5.Enabled = False
End If
If random = 6 And Button6.Enabled = True Then
Button6.Text = "O"
Button6.Enabled = False
End If
If random = 7 And Button7.Enabled = True Then
Button7.Text = "O"
Button7.Enabled = False
End If
If random = 8 And Button8.Enabled = True Then
Button8.Text = "O"
Button8.Enabled = False
End If
If random = 9 And Button9.Enabled = True Then
Button9.Text = "O"
Button9.Enabled = False
End If
End Sub
The computer plays its first move randomly. After the user makes more than one move, the computer can't use the above code because it has to decide according of the user input. Therefore, we also add the following code. The following code is too long, (human being can calculate that in less than a second)

Code:
Public Sub Options()
'If user hits 1
If Label1.Text = 1 Then
If Button2.Text = "X" And Button3.Enabled = True Then
With Button3
.Text = "O"
.Enabled = False

.Text = "O"

The following code will check if there is a winner and show the result on a message box:

Code:
Public Sub CheckIfComputerWins()
If Button1.Text = "O" And Button2.Text = "O" And Button3.Text = "O" _
Or Button4.Text = "O" And Button5.Text = "O" And Button6.Text = "O" _
Or Button7.Text = "O" And Button8.Text = "O" And Button9.Text = "O" _
Or Button1.Text = "O" And Button4.Text = "O" And Button7.Text = "O" _
Or Button2.Text = "O" And Button5.Text = "O" And Button8.Text = "O" _
Or Button3.Text = "O" And Button6.Text = "O" And Button9.Text = "O" _
Or Button1.Text = "O" And Button5.Text = "O" And Button9.Text = "O" _
Or Button7.Text = "O" And Button5.Text = "O" And Button3.Text = "O" Then
MsgBox("Computer Wins")
Button1.Text = ""
Button1.Enabled = True
Button2.Text = ""
Button2.Enabled = True
Button3.Text = ""
Button3.Enabled = True
Button4.Text = ""
Button4.Enabled = True
Button5.Text = ""
Button5.Enabled = True
Button6.Text = ""
Button6.Enabled = True
Button7.Text = ""
Button7.Enabled = True
Button8.Text = ""
Button8.Enabled = True
Button9.Text = ""
Button9.Enabled = True
ElseIf Button1.Text = "X" And Button2.Text = "X" And Button3.Text = "X" _
Or Button4.Text = "X" And Button5.Text = "X" And Button6.Text = "X" _
Or Button7.Text = "X" And Button8.Text = "X" And Button9.Text = "X" _
Or Button1.Text = "X" And Button4.Text = "X" And Button7.Text = "X" _
Or Button2.Text = "X" And Button5.Text = "X" And Button8.Text = "X" _
Or Button3.Text = "X" And Button6.Text = "X" And Button9.Text = "X" _
Or Button1.Text = "X" And Button5.Text = "X" And Button9.Text = "X" _
Or Button7.Text = "X" And Button5.Text = "X" And Button3.Text = "X" Then
MsgBox("Congratulations, You Win")
Button1.Text = ""
Button1.Enabled = True
Button2.Text = ""
Button2.Enabled = True
Button3.Text = ""
Button3.Enabled = True
Button4.Text = ""
Button4.Enabled = True
Button5.Text = ""
Button5.Enabled = True
Button6.Text = ""
Button6.Enabled = True
Button7.Text = ""
Button7.Enabled = True
Button8.Text = ""
Button8.Enabled = True
Button9.Text = ""
Button9.Enabled = True
End If
End Sub
We also need to add a code when the user doesn't make a proper move: (When the computer doesn't have to think because the user didn't make a threatening move)

Code:
Public Sub hit()
For Each ctl As Control In Me.Controls
If Label1.Text < 9 Then
If (ctl.Name.StartsWith("Button" & Label1.Text + 1)) Then
Dim btn As Button = DirectCast(ctl, Button)
If btn.Enabled = True Then
btn.Text = "O"
btn.Enabled = False
Else
Label1.Text = Label1.Text + 1
End If
End If
Else
If (ctl.Name.StartsWith("Button1")) Then
Dim btn As Button = DirectCast(ctl, Button)
If btn.Enabled = True Then
btn.Text = "O"
btn.Enabled = False
Else
Label1.Text = Label1.Text + 1
End If
End If
End If
Next
End Sub
Now we program PC Start Button (Button10): When the user ask the computer to start first:

Code:
Private Sub Button10_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button10.Click

Timer1.Stop()

Button1.Text = "O"

Label1.Text = 1

Button1.Enabled = False

Button10.Enabled = False

End Sub
The last piece of code when the user hit Restart Button: (button11)

Code:
Private Sub Button11_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button11.Click
Button1.Text = ""
Button1.Enabled = True
Button2.Text = ""
Button2.Enabled = True
Button3.Text = ""
Button3.Enabled = True
Button4.Text = ""
Button4.Enabled = True
Button5.Text = ""
Button5.Enabled = True
Button6.Text = ""
Button6.Enabled = True
Button7.Text = ""
Button7.Enabled = True
Button8.Text = ""
Button8.Enabled = True
Button9.Text = ""
Button9.Enabled = True
Button10.Enabled = True
Timer1.Start()
End Sub

Eh it's actually pretty easy to make this if you know how to make a keygen then this is a snap.
#2 ·
Yeah easy to make, but tic tac toe are so fun :3
Thanks for the tut, it will help beginners i guess =)
#3 ·
Cool,I will make this later on.Thanks
#5 ·
I don't understand this game
#6 ·
please put picture I'm a newbie with this ..

Oh, Grrrrrrrrrrrrrrrr.... OP has one post, there is a picture or two, and you bumped a topic that's over a month old.

Read MPGH Rules, and more specifically VB rules, no bumping if last post in thread is >= 7 days.

Create a thread or PM someone.

Sorry Closed.

What a shame.
