VB.NET

Code moved to the "What I have done" section of the question

now what i need to do is to make a function that finds which of the buttons is clicked the last one out of 4 of them and then finds out which player clicked that button by checking its color. The player that clicked the last button takes 1 point

You just need a single variable. Every time a button is pressed save its details in that variable: that is the last button that was pressed.

how , exactly?

By writing some code. Come on, you said this is a university project, so you are expected to use your brain to solve it, not sit around expecting someone else to do it for you.

Dim buttonList As New List(Of Button)

Private Sub buttons_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles b1.Click, b4.Click, b5.Click, b8.Click
Dim selectedBtn As Button = sender
buttonList.Add(selectedBtn)

End Sub

Public Sub checkitems()

For Each b As Button In buttonList
If b.BackColor.Equals(buttonList(3).BackColor) AndAlso buttonList(3).BackColor = Color.Red Then
Label5.Text += 1
Else
Label6.Text += 1
End If
Next

End Sub

I dunno if im correct but the list is been created from clicked buttons but how can i found out the color of the highest index button in the list and test it if is red do that specific thing else do the other ?

Solution 1

So create a class level List of Buttons, and handle their Click events.
In the handler, check if the button has been added already, and if so, remove it.
Then add the button.

Since a List is ordered by "last entry at the end" you just need to fetch the item with the highest index, and that is the last pressed.

Hint: you can use a single event handler for any number of buttons - the Button that was clicked is passed to it as the sender parameter.

Can you give an example please ?!

OriginalGriff 4-Apr-21 10:42am

Which bit? You should know how to do all of those things ...

You know how to create a List, I assume?

i"m a little bit new here, its a university project and i'm not very good at it, plus im running out of time.
Would u help me !

OriginalGriff 4-Apr-21 11:54am

Does that mean you do or you don't know?

I only get exactly what you type to work with, I can't see your screen, access your HDD, or read your mind...

Daniel Peqini 4-Apr-21 12:08pm

I do not

OriginalGriff 4-Apr-21 12:36pm

Oh, come on!
You don't know how to create a list?

Dim clickedButtons As List(Of Button) = New List(Of Button)()

Public Class Form1

Public ply1, ply2 As String
For Each c As Control In Panel1.Controls

If c.GetType() = GetType(Button) Then
AddHandler c.Click, AddressOf btn_Click

End If

Next

End Sub
Dim Xor0 As Integer = 0

Public Sub btn_Click(ByVal sender As Object, ByVal e As EventArgs)

Dim btn As Button = sender

If btn.Text.Equals("") Then
If Xor0 Mod 2 = 0 Then

btn.BackColor = Color.Blue
Label1.Text = ply2 + "'s Turn"

Else

btn.BackColor = Color.Red
Label1.Text = ply1 + "'s Turn"

End If

Xor0 = Xor0 + 1
End If

End Sub

Private Sub CreateButtons()

Dim xPos As Integer = 0

Dim yPos As Integer = 0

Dim n As Integer = 0
For i As Integer = 0 To 3

Next

End Sub

End Class

This is my code so far
