Hello all. I am designing a small little game to take a break from FOH and get a bit better at coding in general, and i have gotten to a point where i need to start saving a little bit of data(just max health, money, upgrades, etc. its like a temple run type game.) and i have never worked with these for saving. i understand how to write them and how to read them with code, but i have one issue. creating it and putting starting data in it. is there an easy way to say like
if the INI doesnt exist/is blank/whatever or if this global.maxhp is undefined then global.maxhp = 1 or whatever?
or is there a better way to get save data of just a few variables into the game? I am thinking of porting this game to HTML or something, maybe IPhone if i spend enough time on it. is there a way of saving that would work no matter the system? or atleast works with regular gm and then the in web browser version?

You would either ship the ini file with your executable and encrypt it, or you would need to write the ini file from GM as if it were a text document, save it with the .ini extension, and then read from it.

Encrypting it would be silly. I see the purpose, but it's not like a game is a high security environment. Plus it will slow down loading.
Otherwise, it's simple enough like Jeod said to just write it as a text file from GM or whatever language you're using.

What I usually do:
if file_exists("gameData.ini")
{
//do all my loading here - I will call my global loading of the ini here as well usually on the title/start screen
global.saveFile = ini_open("gameData.ini");
//finish loading each variable or you could just have the game load from the ini on the fly instead of loading into global variables
}
else
{
//Game Maker 8.1 and older
temp = file_open_write("gameData.ini");
file_close(temp);
global.saveFile = ini_open("gameData.ini");
//Game Maker Studio
ini_open("gameData.ini");
//note that GMS only creates the ini if you write data to it so you should have your keys created after you open the ini
}
That code isn't perfect as I haven't used it in a while and I no longer have GM 8 installed to check it. GM Studio changed the file system and it seems a bit wonky. You should look into the manual if you are using GMS as it already includes many levels of encryption standard now from base64 upto SHA-1.

Thank you both, i will try those suggestions. I am in Game Maker 8 but wish to transfer over to GMS, so i may as well do that sooner or later. thank you both for the replies!
