static function GetBool (key : String, defaultValue : boolean = false) : boolean

Description

Returns the value corresponding to key in the preference file if it exists.

If it doesn't exist, it will return defaultValue.

Round rotations/positions and remember the active option.

// Simple script that lets you round rotations and
// round your positions of your selected objects.
// and it remembers which option is being active
