Hi Nadester,
1. If you have multiple file you can make different INI files and after changing your one level you can open tree_5.INI file for this level.
2. About security, I am using INI files for my cars, trees, lights, traffic lights, traffic rules, task_points, etc ... About security i have made following solution :
- Change your all .INI file's extension to .PAK file
- bind all your .PAK files to your .WRS archive.
- At startup you have to load all your INI files. Then use file_cpy function to extract and copy your .PAK files from .WRS to .INI files.
- After call your READ_INI functions.
- That's it !
If some people want to change your ini files, it has no effect. You will overwrite your ini files from your .WRS at every startup of your game.
