[MAP] Sprinting from tiles to dirt interrupts sprinting on Nacht der Untoten

[Peter0x44]

To Reproduce Steps to reproduce the behavior: 1) Load up Nacht der Untoten. 2) Begin sprinting on the tiles and run onto the dirt. 3) Notice your sprint gets interrupted.

Expected behavior The sprint continues as normal.

Affected Platforms I tested this only on FTEQW.

Additional context The sprint does not get interrupted when running from the dirt to the tiles.

This happens with stairs too, it is more general than that. You can sprint up stairs but not down them.

My best guess is this relates to player physics more than it being a map issue. The abrupt change in geometry must be toggling the player's "onground" flag, interrupting the sprint (as if the player has walked off a ledge). I'm not sure what the fix might look like, but core features such as player movement require pretty thorough testing.

Two fixes come to mind:

1. Only allow sprinting to be interrupted on some more strict condition(s)
   • Falling farther than some vertical distance?
   • Downward speed greater than some threshold?
   • "onground" flag missing for more than 0.1 seconds?
2. Adjusting the player physics movement to provide some sort of "stiction" when walking down stairs?

Yes, this was my conclusion too. The title was wrong, will update.
