Summary

0003039: ThrustThingZ Actor hits floor specials act differently between 2.1.2 and 3.0

Description

This is the same in GZDoom.

When landing on ThrustThingZ actor hits floor special sectors with +jump active, you would previously be thrust further upwards than when +jump is not active. This is only the case in Zandronum 3.0 for every other jump rather than every single time. This behavioral change could screw up mods that make use of these types of jump panels such as MM8BDM and Jump Maze.

Steps To Reproduce

1) Load the example wad in Zandronum 2.1.2
2) Enter MAP01, land on the sector with the red dots texture while holding jump.
3) Repeat the previous steps for Zandronum 3.0 beta 170205.
-- The resulting height should be lower for the first jump, but then reach the same height for the second jump.
-- Every odd numbered jump after that will be low, every even number high. This pattern resets upon landing on a sector that doesn't have a ThrustThingZ special that is activated on actor hits floor.
4) This is the same in GZDoom 2.3.2

Additional Information

The biggest thing to note is that this change impacts how Jump Maze handles things. They almost inevitably use this manner of jump panel because it's intuitive and easy to implement.

Notes
(0016996) Torr Samaho (administrator) 2017-03-18 16:37	So GZDoom 2.3.2 behaves like Zandronum 3.0 currently does? If so, can you make a bug report at the GZDoom tracker?

(0017035) Cutman (reporter) 2017-03-20 19:03 edited on: 2017-03-20 19:03	Note that we can band-aid 8BDM for 3.0 if this behavior remains. I can't say the same for other mods that rely on it though.
