Summary

Function: llSetCameraAtOffset( vector offset );

Sets the point the camera is looking at to offset for avatars that sit on the object.

• vector offset offset relative to the prim's position and expressed in local coordinates

This is the point the camera looks at, not the position of the camera's eye.

Caveats

  • Setting this will not update the cameras of seated avatars, it will only effect avatars that subsequently sit down. The camera settings have to be prepared in advance.
  • The offset is locally relative to the object, if you want it relative to the seated avatar (which likely has a custom sit rotation and offset) or the region, you must do the computation yourself.
  • ZERO_VECTOR offset will cancel any offset.
  • Camera focus set by this function is a Prim Property. It will survive the script and it will survive prim taking and prim rezzing

Examples

// Set the seated avatar looking at an arbitrary direction
// Look over the avatar's shoulders from behind once it sits down

back_view(float degrees)
{
     rotation sitRot = llAxisAngle2Rot(<0, 0, 1>, degrees * DEG_TO_RAD);
    
     llSitTarget(<0, 0, 0.1>, sitRot);
        
     llSetCameraEyeOffset(<-2, 0, 1> * sitRot);
     llSetCameraAtOffset(<2, 0, 1> * sitRot);
}
