Simple Problem

[Black_Epiphany]

I am creating a text-based rpg. I need a way to create save files for the stats of a character ( a bunch of integer variables ) to any directory on the pc and be able to load them at will the next time the program starts.

Any tutorials or tips you can help me with?

Start with basic file i/o

Instead of specifying a particular directory, have the game data file use the same directory as the game program file, uses. No specification should be needed for that, completely avoiding the whole "what directory" problem.

Also, to expand on stahta01's post, you specifically want to be looking at doing binary files for this and here is our Tutorial on File Operations

That may not be as simple as it seems, especially on Vista and Win7...

User Account Control Data Redirection

Depending upon a user's priveledge level their file i/o and registry i/o might take something of a left turn on them...

I am on Linux (ubuntu) btw. Thanks for the help guys.

I really like this forum. Much better and friendlier than others I have tried in the past.

I'm on Win7 and have had no problem with file access for any of my programs, but I am also logged in with high authorization. I also run a Ubuntu rig, and it handles file access similarly, but again, I'm logged in with high authorization.

@Black_Epiphany, we're just going easy on ya!

Actually the whole redirection thing is defeatable anyway... Just add a manifest to the executable's resources...

Changes will be needed on a program by program basis for the assembly name (program name without extension), assembly description and platform (x86 or amd64 in most cases).
