[Opensim-users] llVolumeDetect

[Dahlia Trimble]

Assuming you're correct about it losing the property after a restart, I'd
think this test would work in either SL or OpenSimulator:

changed(integer what)
{
        if (what & (CHANGED_REGION_START | CHANGED_REGION_RESTART))
         {
                 llVolumeDetect(FALSE);    // toggle bug fix in Opensim
                 llVolumeDetect(TRUE);
         }
}
