Reading other files (ini, txt)

I am making a game that needs to read a long list of coordinates from another file for my collision detector, but I don't know how to do that. I saw someone do something similar using

Open App.Path + Filename For Input As #1

but I don't know how to use it. Any help would be welcome.

if the number of coordinates remains constant the easiest way would be to use a binary file and use put and get directly into an array.

To read from an InI file

VB Code:

Private Declare Function GetPrivateProfileString Lib "kernel32" Alias "GetPrivateProfileStringA" (ByVal lpApplicationName As String, ByVal lpKeyName As Any, ByVal lpDefault As String, ByVal lpReturnedString As String, ByVal nSize As Long, ByVal lpFileName As String) As Long
Private Declare Function WritePrivateProfileString Lib "kernel32" Alias "WritePrivateProfileStringA" (ByVal lpApplicationName As String, ByVal lpKeyName As Any, ByVal lpString As Any, ByVal lpFileName As String) As Long
Private Sub Form_Load()
    'KPD-Team 1999
    'URL: [url]http://www.allapi.net/[/url]
    'E-Mail: [email][email protected][/email]
    Dim Ret As String, NC As Long
    'Write the setting to the file (c:\test.ini) under
    '   Project1 -> Keyname
    WritePrivateProfileString App.Title, "KeyName", "This is the value", "c:\test.ini"
    'Create a buffer
    Ret = String(255, 0)
    'Retrieve the string
    NC = GetPrivateProfileString(App.Title, "KeyName", "Default", Ret, 255, "C:\test.ini")
    'NC is the number of characters copied to the buffer
    If NC <> 0 Then Ret = Left$(Ret, NC)
    'Show our string
    MsgBox Ret
End Sub

I already have something like this that I use. I was wondering how I coudl use something simple, easy, and without knowing how many coordinates would be entered. (So that the user might make a map of his own)

you could still do that
just save a long/integer specifying the number of coordinates stored and than dimension an array with that lenght and load it.

Thnx. But do you know what the "Open filename for input as #1" means and how i could use it?

Using "Open filename for input as #1" is VB 101.

If you have VB installed, look at the help file.
