Load/Save a game

Hi there!I'm making the Hanoi game on vb,but I don't know how can I make a procedure so that the player can save his game and load it at anytime.I'll appreciate if anyone can help me.Thanks.

Hmm... what kind of game it is?

I think the easiest way to make a save is something like this:


'cmdSave.Click

open "d:\path\save.ext" for output as #1

print #1, strVar1
print #1, strVar2
print #1, strVar3
print #1, intPlayerXPos
print #1, intPlayerYPos
'use the write # statement for boolean values

close #1

'cmdLoad.Click

open "d:\path\save.ext" for input as #1

line input #1, strVar1 'not sure about this, check the msdn help
line input #1, strVar2
line input #1, strVar3
line input #1, intPlayerXPos
line input #1, intPlayerYPos

close #1


If you'd like, I could put here a save/load procedure from a game I'm working on... It works like above, but in addition it crypts the save file so it can't be edited :p

BTW: Again I'm sorry I can't use that vbcode function here... :confused:
Have to learn someday.

That is, in my opinion, the easiest yet most flexible way of loading and saving game data.

Yep. Heres some sample code: (use in a module)

Code:

---

'Types
    Type tREPLACE_NAME
        Value1 As Long
        Value2 As String
        Value3 As Integer
    End Type
   
'Variables
    Public REPLACE_NAMECount As Long
    Public REPLACE_NAME() As tREPLACE_NAME

Sub LoadData(iFileName As String)
    Dim FileNumber As Integer

    'Reset
    Reset
   
    'Verify filename
    If Not Exists(iFileName) Then
        'Error: File not found
       
        Exit Sub
    End If

    'Read file
    FileNumber = FreeFile
    Open iFileName For Binary As FileNumber
        'Count
        Get FileNumber, , REPLACE_NAMECount
       
        'Data
        If REPLACE_NAMECount > -1 Then
            ReDim REPLACE_NAME(REPLACE_NAMECount)
           
            Get FileNumber, , REPLACE_NAME
        End If
    Close FileNumber
End Sub

Sub SaveData(iFileName As String)
    Dim FileNumber As Integer

    'Delete file
    If Exists(iFileName) Then: Kill iFileName

    'Write file
    FileNumber = FreeFile
    Open iFileName For Binary As FileNumber
        'Count
        Put FileNumber, , REPLACE_NAMECount
       
        'Data
        If REPLACE_NAMECount > -1 Then
            Put FileNumber, , REPLACE_NAME
        End If
    Close FileNumber
End Sub

CAnt we just create a new "extension" like .sav and put stuff on it like in Diablo or other game like that ?

What's the problem?

Use my function like this:

Code:

---

SaveData "test.sav"

---

Extensions do say nothing about the file contents/format. In windows the header is important but if you're making savegames you can just use a function like mine and put the data in... you can chose any extension you want, even .exe .com .txt -" .savegame of my file" - whatever
