  'How would you like the feature to work?': 'The proposal is to have a new CHANGED_REGION_COMPLETE bit sent to scripts via the "changed" event. Proposed behavior:\r\n\r\n- When an object changes regions, CHANGED_REGION is sent, as at present.\r\n\r\n- When an object with seated avatars (usually a vehicle) changes regions, its scripts receive CHANGED_REGION when the object crosses, and the new CHANGED_REGION_COMPLETE only when all seated avatars have arrived, are fully operational in the new sim, and are ready to accept animation, sound, and take controls requests.\r\n\r\n- CHANGED_REGION and CHANGED_REGION_COMPLETE bits can both be set in one event message. This is the normal case for ordinary object crossings not involving sitters.\r\n\r\n- Avatars sitting on vehicles should receive CHANGED_REGION when the avatar crosses, and CHANGED_REGION_COMPLETE when the vehicle and all avatars have completed the crossing. That\'s the same time the vehicle receives it.\r\n\r\n- If CHANGED_REGION_COMPLETE does not follow CHANGED_REGION within a few seconds, a region crossing problem has occurred.',

  'Why is this feature important to you? How would it benefit the community?': 'Region crossings are not instantaneous. Vehicle scripts need to be aware of that to do a good job. Especially since cloud uplift to AWS, which sped up object crossings. Vehicles now usually arrive before avatar passengers. That change broke some vehicle scripts.\r\n\r\nThis has caused problems with scripts asking for animations (which produces an error popup) or falsely detecting that an avatar is missing (which causes the script to shut down the vehicle. There are workarounds, ways to detect that a region crossing is in progress, but they are complicated, involve fast timers,  and are not widely used. This provides a simple way for scripts to cope with that delay. \r\n\r\nDiscussed at Server User Group on July 6, 2021.',
