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.

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 the an 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 for the menu scene, containing...

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