Summary

0008273: CHANGED_TELEPORT is triggered on some border crossings

Description

When you walk or fly across a region border the changed() event is sometimes called with the CHANGED_TELEPORT bit in the parameter.

This most often happens when you walk or fly across a region border going north to south or east to west. But on some border crossings in those directions changed() is not called with CHANGED_TELEPORT. So fly around until you find a border where this happens. Once you find a border with the problem it will consistently demonstrate the issue. I have never seen the bit set when crossing south to north or west to east.

I'm not sure what the correct behavior is. I know that crossing a border is similar to teleporting to another region. Should this bit be set on any crossing? Or suppressed since a crossing doesn't feel like teleporting?

HOWEVER, either way it should be consistent and not different depending on what direction you are crossing.

Steps To Reproduce

Put the following script in a prim, wear the prim as a HUD or attachment. Fly back and forth across several borders and look at the messages in chat.

Additional Information

//Put the following script in a prim, wear the prim as a HUD or attachment.
//Fly back and forth across several borders and look at the messages in chat.
//sometimes you will see the CHANGED_TELEPORT bit appearing on a border crossing
//I think that bit should not be there on a border crossing
default
{
    state_entry()
    {
        llSay(0, "reset");
    }
    changed(integer flag)
    {
        if (flag&CHANGED_REGION)
            llSay(0,"Changed Region");
        if (flag&CHANGED_TELEPORT)
            llSay(0,"Changed Teleport");
    }
}
