Hey, i had my class setup and working, but it wasnt reading from the file and was being defined at the start of the main function.
So i added in a function which reads from the file the users settings, if it does exist it gets created, kinda simple (it worked 100% when i used local variables).
So then i decide to link it up to the classes variables to obviously get it globally, and i get a huge load of errors for each time these variables are called.
Errors: (yeah i was gona try and do a netstorm remake)

I know im using the C and not the C++ library for reading files, but i find this way alot more logical. (also that isnt the error). The comments ive made are just notes for me so i remember what each part does when i look back at it in a few weeks.
I also realise i shouldnt use atoi without checking the string first, but this is really getting it working first.
Thanks in advance
Smoke me a kipper, ill be back for breakfast.
