Moving platforms touching sector portals break physics

[boris]

Version: g3.7pre-912-ge05cedfc0 (but it's been like that before)

Setup: have a platform that moves up and down, and touches a sector portal, like a lift carrying the player through a portal. If the platform is fully up, it will no carry the player down with it unless the player moves. I.e. if the player stands still the platform will go down, but the player will hover in the air.

Video demonstrating the behavior:



Example WAD is attached.

This actually seems to affect all actors, not just the player. If you put something, like a medikit, on the platform, it will not go down with the platform, but fly in the air.

I guess I am experiencing a similar problem here, since same actor works on non-moving / changing sectors with portals

I wonder what boris is up to when he is currently mapping...

The problem here is that the actor is completely in the upper sector and the lift completely in the lower one. This causes the actor checker for the plane movement to miss it.
Until this gets fixed I recommend not to let a moving plane occupy the exact same position as a portal.

That introduces another problem: you can't walk off the platform, except for the north-west corner. And even there it's unreliable (shaking the mouse left and right while walking forward seems to help).

[edit] what I did was change the script to raise/lower the platform by 127 units instead of 128.

Nothing much, just noticed it while working on my JoM 6 map.
