BOOMEDIT: Line 247 and 248 - Displace Scroll Objects on Tagged Floor
In BOOMEDIT, there is a section for lines 247 and 248 to test the Boom behavior. in ZDoom, Eternity, and PRBOOM+, the eyes do not leave the conveyor belt when the lift is used, instead they move back to their original starting position as the lift goes back up. in Odamex with co_boomphys 1 and co_zdoomphys 0, the eyes are projected off of the conveyor belts. Setting co_zdoomphys 1 does not resolve the problem either. Happens in single player.
possibly related to bug 1142
Fixed in this commit : https://github.com/Ch0wW/odamex/commit/bc335306aacae311e076c590163869728f2e9751 .
HOWEVER, bug 1142 is entirely different, and is fixed in ZDoom 1.23, as it's also present in ZDoom 1.22 !
