Trouble creating/writing to file.

[Netherwulf]

Greetings!

I'm hitting a wall trying to create a game state file that can be opened and read back. Here is my code.
 

filePath = FileSystem:GetAppDataPath() .. "gamestate.txt"


function Script:UpdatePhysics()
	
	if window:KeyHit(Key.S) then
		local stream = FileSystem:WriteFile(filePath) 
		if (stream==nil) then Debug:Error("Failed to write file.") end

		stream:WriteInt(GameData)
		stream:Release()
	end

end

When I run the program and press the key to create and save the file, the debug error is fired and the program ends. I can't tell if the problem lies in my code or somewhere else.

I worked on this and it runs ok in this code order:

DISPLAY was the variable I wanted to save written.

        local path = FileSystem:GetAppDataPath().."/MyFile.txt" 
        FileSystem:CreateFile(path) 
        local stream = FileSystem:OpenFile(path) 

        if (stream) then
                stream:Seek(0) 
                stream:WriteLine(DISPLAY) 
 --               stream:Seek(0)   -- debug
 --               System:Print(stream:ReadLine()) 
                stream:Release() 
        end

Your second code shows a "/" is inserted, and the first one does not.

The path being in the proper format was the first thing I looked into when I started having trouble. That doesn't seem to be the issue. 

Furthermore, I tried using the FileSystem:CreateFile() and FileSystem:OpenFile() commands that Marcousik suggested, but that doesn't work for me either. My local "stream" variable continues to return a nil value.

UPDATE: I finally got it to work. It seems that I had "Sandboxing" enabled in the editor's options and that was preventing it from working. Thanks for all your help.
