[GZDoom] Sector special 37 (Heretic) effect scrolls too fast

Post by Sinael »

Sector special 37 (Heretic) effect scrolls too fast, also failed action linedefs

During playtesting of the map E2M4 of the following map pack for Heretic
It was discovered that voodoo doll contraption that works fine in ZDoom fails to work properly in GZDoom.
During further testing it was revealed that sector special 37 results in much stronger push in GZDoom than it has in ZDoom.
For instance in GZDoom it has roughly the same pushing speed as the player normal walk speed, so if you walk against the scrolling direction you will stay in one place, while in ZDoom the pushing force is easy to overcome with simple walking. The push speed in GZDoom is more than double of what it should be.

Here is a video link with demonstration of the same map part in GZDoom first and then in ZDoom : https://my.mixtape.moe/vihrye.webm

Here's how it looks in game:
ZDoom : https://my.mixtape.moe/smwnjk.webm
GZDoom : https://my.mixtape.moe/igqudy.webm

I don't know if other scroll specials are affected or is it just this one. Also note that several action linedefs failed to trigger in GZDoom, when they should've been triggered even at that speed, which is, I think, a different bug.

Here's an edited version of E2M4 for easy testing (as E1M1) - starts off right before the switch that triggers the voodoo doll sequence (stairs rising) that goes wrong. http://www.mediafire.com/file/v11cr67yi ... MPE2M4.wad

Check your compatibility settings. There's an option in there to change this scroller's speed.

If you are about "Raven scrollers use original speed" then it does not affect this one. Not in GZDoom at least.
In ZDoom checking it on breaks the sequence in question, so I assume it works there, and the GZDoom one is broken to be always on.
Still, line actions not being activated is a bug as well.

Scroll speed was incorrect in the latest stable ZDoom: speed adjustment was applied to all scroll directions but it should affect east direction only.
This was fixed in this commit.

For the same reason the mentioned compatibility option doesn't change anything in the provided map as special 37 is Scroll West at speed 25.
Use special 35 (speed 5) to make it work again.
