I need to create a function that lets the player save and load a game, how do I do this?

Take a look at WriteFile and ReadFile in the help area of Blitz3D.

It writes fine, but when I try to load it using readint,readstring,ect., it says"stream does not exist", even after I load the file with "readfile("myfile.dat")" or "readfile("myfile.dat")" i've tried "variable=readfile("myfile.dat")" and "readfile(file1)" file1 is what is called the file handle.

Take a look here:

It's not very efficient as a whole but the basics you need are there.

Don't use ReadInt, ReadString, etc. use ReadLine.

Nothing wrong with using readint and readstring, as long as you make sure you wrote them with writeint and writestring

There is a lot of threads in the forum about it. Search...

i've tried "variable=readfile("myfile.dat")" and "readfile(file1)" file1 is what is called the file handle.

;create a file and put something in it
file1 = WriteFile("myfile.dat")
  WriteLine file1,"Hello"
CloseFile file1

;read file back
file1 = ReadFile("myfile.dat")
While Not Eof(file1)
  s$ = ReadLine(file1)
  Print s$
Wend
CloseFile file1

Don't use OpenFile - it will fail on read-only files.
