ULTIMA: falling down is not happening

[farmboy0]

A bit east of Tenebrae is a small destroyed hut which when stepped into opens up the ground and you fall down to a dungeon below. This doesnt happen with ScuzmmVM.
Ill attach a save right outside the hut.

Step into the hut and the ground will change but you will not fall down.

Thanks. I have noticed the same problem and worked on a good fix for it, but it turns out it's quite hard to fix without introducing other problems.

The "support" calculation is using the avatar's full hit-box, but it should be a smaller box it seems. Unfortunately just modifying that box causes other problems (specifically with stairs) so it kind of cascades. I'll leave this open as I still want to find a good fix for it.

It's not impossible to fall down this hole by the way, just much harder than it should be!

The primary thing making this difficult is an item, Shape 596 - Jewelry, that stays in airs when the floor crumbles. This item also stays in air in the original game. However, is the original game this shape does not block movement or support the player if stood upon despite being marked as solid.

Moving this item allows falling easily.

Another note: the jewelry will block the player movement in the original game if on floor of a room with a low ceiling like the jewelry shop
