[RESOLVED] I need help with a score problem in my vb 2008 game

Hi guys, i am making a guess the number game, i have all that down good, now i am adding a score system. I thought i had it good, but it takes away all the points i put in for the different difficulties.
like, if you get the number on the easy level you get 1 point
Points:
easy = 1
medium = 5
hard = 10
impossible = 100

and if you get it wrong it takes away 1 point

but when i get it wrong, it takes away 5 points, and if i get it right i get 116 points

please help me.

Code:

Its a bit difficult working out the logic of your code when all your controls have names like text1 and label3 - its a good idea to give them meaningful names, and adding a blank line here or there to visually split out parts of the code is a good idea too.

The first thing I can see without even looking at your code is that the points you are getting awarded is the sum of the points available for the different levels, ie you seem to be getting easy + medium + hard + impossible, so thats the first thing I would look for : is your code running all four "correct" blocks somehow.

Also note you are incrementing text values. This works but it is bad practice and if you had Option Strict set to On (which I'd recommend) it would be giving you errors. Things like "Score.text -=2" are logically incorrect.

Oh ok, i tried setting the score as an integer, but then i could not get it to display.
I will name all the code, just give me a minute

I think this is your actual problem - you have got your End If statement in the wrong place after checking the difficulty level.

Code:

---

        ' Easy difficulty
        If RadioButton1.Checked = True Then
            Label1.Text = random.Next(1, 10)
        End If

---

This End If should come at the end of the block that handles the points like this :

Code:

---

        ' Easy difficulty
        If RadioButton1.Checked = True Then
            Label1.Text = random.Next(1, 10)
     
            If TextBox1.Text = Label1.Text Then
                'add score
                score.Text += 1
                '
                Label2.Visible = True
                Label3.Visible = True
                Label3.Text = "You are CORRECT!"
                Button1.Enabled = False
                TextBox1.Enabled = False
            Else : Label2.Visible = True
                ' minus score
                score.Text -= 2
                '
                Label3.Visible = True
                Label3.Text = "You are WRONG!"
                Button1.Enabled = False
                TextBox1.Enabled = False
            End If
        End If

---

Because your If..End If is only wrapped around the bit that generates the number to guess and not the points and doesn't wrap the point scoring, it means that the point scoring for each difficulty gets run each time, hence it is accumulating the correct or incorrect scores for each level every time.

Obviously you need to correct this for all four blocks - I've just shown one example above.

Ok i fixed it,

Code:

---

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles GuessButton.Click
        Dim random As New Random
        ' Easy difficulty

            randomnumber.Text = random.Next(1, 10)
        End If
        If PlayerGuess.Text = randomnumber.Text Then
            'add score
            score.Text += 1
            '
            numberwas.Visible = True
            WrongRight.Visible = True
            WrongRight.Text = "You are CORRECT!"
            GuessButton.Enabled = False
            PlayerGuess.Enabled = False
        Else : numberwas.Visible = True
            ' minus score
            score.Text -= 2
            '
            WrongRight.Visible = True
            WrongRight.Text = "You are WRONG!"
            GuessButton.Enabled = False
            PlayerGuess.Enabled = False
        End If
        ' Medium difficulty
        If RadioMedium.Checked = True Then
            randomnumber.Text = random.Next(1, 50)
        End If

Oh thanks! I will test that now

Thank you, it worked!

In order to get around the problem of using text to hold the scores you want to declare a local-level integer variable to hold the score. You then increment/decrement this with the score each time and then set the Score.Text = the score variable.

Incidentally it took me a while to get my head round your logic because for a number guessing game you would usually have the game and pick a number and then the user tries to guess it - in your code its more of a "predicting" game because the user picks a number and then the computer picks one and you win if you correctly predicted it!

I will attempt that.
Wait, how do i do that lol, im still new to vb, when i tried

Code:

---

Dim score as integer = 10

---

it didnt work
and when i tried

Code:

---

Dim score as new integer

---

i didnt know how to add the score

You need

Code:

---

Dim currentscore as integer

---

And place that between the 1st line of code ("Public Class Form1") and the start of your button click event. Variables declared there will have local scope (ie will be visible and accessible in all procedures within the class).

If you had "Dim currentscore as integer = 10" then the user would start the game with a score of 10.

Then when it comes to your scoring code, you want something like :

Code:

---

' Easy difficulty
    If RadioEasy.Checked = True Then
       
        randomnumber.Text = random.Next(1, 10)
     
        If PlayerGuess.Text = randomnumber.Text Then
            'add score
            currentscore += 1
            '
            numberwas.Visible = True
            WrongRight.Visible = True
            WrongRight.Text = "You are CORRECT!"
            GuessButton.Enabled = False
            PlayerGuess.Enabled = False
        Else : numberwas.Visible = True
            ' minus score
            currentscore -= 2
            '
            WrongRight.Visible = True
            WrongRight.Text = "You are WRONG!"
            GuessButton.Enabled = False
            PlayerGuess.Enabled = False
        End If

        score.text = currentscore
    End If

---

Although another note on good practice, having a textbox called score and a variable called score is not a good idea (if it works at all), likewise having a variable called "random" of type "Random" is going to lead to problems (especially as VB.Net is case insensitive)

Thank you for all your help, sorry for the delay in this last post, i was having dinner.

No problem - but if your problem is fixed now please remember to mark the thread resolved using the thread tools menu at the top of the thread.

Done :)
