// Sit Adjuster, Jeff Kelley, 2024
//
// This script allows interactive adjustment of the sit position.
// Put the script in a seat, then sit. Mode (POSITION or ROTATION),
// avatar position and avatar rotation are displayed in green.
// Adjust the position using the arrow keys + PageUp/PageDown.
// Once satisfied, click on the seat to enter ROTATION mode
// and adjust the rotation. Toggle between POSITION and ROTATION
// as many times as necessary. Finally, standup. The new sittarget
// is now written, and the script deletes itself.
//
// PLEASE NOTE - It is strongly advised to disable the setting :
// Preferences > Move&View > Reset camera position on avatar movement
// so the camera won't jump when you hit the arrow keys.
