"Sticking" player to floor when going down stairs?

[Nash]

Does anyone know a simple way to "glue" the player to the floor when walking down stairs? Currently with a fast moving player, you will just overshoot the stairs and end up floating in the air when descending stairs.

ZScript and custom player pawn welcome.

Not easily. The movement logic already contains code that allows an actor to step down stairs, but this logic will fail if you overshoot the stairs due to too high velocity, because this will be considered moving over a dropoff which results in gravity pulling you down.

I agree it would be cool to have something like this in.

This resource from 2016 may be a good starting point. Note that it's written in ACS so it'd first have to be ported to a custom player class.

One possibility I can imagine is to check, every tick:
- previous floorz
- current floorz
- previous onground status

and use setz to snap the player to the current floorz if
- the current floorz is less than previous floorz
- the difference does not exceed maxstepheight
- previous onground status is true

[Graf Zahl]

That won't do anything because the engine already does it. Like I said above, the problem comes when the player overshoots the next lower stair and the difference between z and floorz is already LARGER than maxstepheight.

I've been thinking a bit about this. I don't think this will ever work script-side. The player's view will "snap" down to the next lower step. There's some hardcoded stuff to handle vertical camera interpolation, but altering the player's Z via brute force through scripting will most probably violently jitter the camera downwards.

What you want here wouldn't even work in real life.
Imagine some person running full speed across some stairs. They'd jump across a lot of steps as well because in order to step down properly you have to move slowly.

......huh. That is surprisingly subtle. So that's why stuff seems to drop just a bit faster than midair gravity would suggest....
