Read/Write Config.ini (CMS)

Name	Type	By
Read/Write Config.ini	Definition	AFRLme

This script allows you to read from/write to the config.ini file. This script is required for anyone wanting to create a professional game menu which stores & remembers each players option configuration. By default Visionaire Studio would load the default settings on game launch.

Please note that, not all of the options included in the config.ini script below, are official parameters. Some of them are custom options, that have just been added as an example. Custom options require you to determine what they do inside of your game, as they do not automatically affect anything. For a list of default parameters, please see here.

Instructions

This script is a little too flexible & complicated for me to create a proper step by step guide. I would instead recommend looking over the script, & checking out the demo I have linked in the resources section below.

1. Add the main script to the Visionaire Studio Script Editor & set the script as a definition script.
2. Edit the script to suit.
3. Create conditions & values (in vs editor) - they should reflect the conditions & values listed in the script.
4. Assign default values (integer & string for values, boolean for conditions).
5. Create a condition that will be used to determine if settings have been changed. This condition should be set to true each time an option is changed. Name it: cfg_update.
6. Don't forget to set the correct condition/value for edited settings; they should reflect the current settings value.
7. To read from the config.ini: add an execute a script action to the game launch action, or inside of a at begin of scene action for the menu scene, containing...

read_ini()

8. To write new settings to the config.ini: add an execute a script action to an at end of scene action - or left click action of a scene object - for the menu scene, containing...

if getObject("Conditions[cfg_update]"):getBool(VConditionValue) then
 write_ini()
end
