Thank for play with me this Back to xen conversion.
I will fix softlock in elevator part !

• In first map, upper part of the box that contains turret inside will remain floating if rest of it is destroyed. Also in the first map, in a room with stacked large crates, one of the boxes will keep floating if everything underneath it is destroyed;
• Second map contains teleport that isn't seamless(doesn't preserve angles and velocity);
• Second map definetly wasn't meant to use same sky texture in all segments. trigger_changesky can be used to change it for each player.

"one of the boxes will keep floating if everything underneath it is destroyed;"
actually.. i really wonder about that.. boxese still keep floating.. even if that has a psuable trigger.. weird i will check again that !

"trigger_changesky" this trigger.. i will learn moree !

"Second map contains teleport that isn't seamless" about this i will re-adjust !!

thank for report !!

SV BOY 11 May 2023 18:49

it would help a lot if you would add checkpoints to your conversions if your map supports survival mode, the map even announces when the respawn changes with the "Respawn Changed" text, you can put checkpoint when these show up, asking this since it may be tough for newer players

also some of map transition teleports are rough

SV BOY 11 May 2023 18:53

Vaelastrasz 13 May 2023 03:47

thanks for report !!
