Paranoidiac.zip: Floating or Sinking Models

[Rex Claussen]

I have found a couple of models (see below) on which gravity behaves differently in paranoidiac.zip than in the original game. For now, I'm simply documenting the issues. We can work on identifying why this is happening and applying the fixes later.

This model is floating [Map03: x=5360/y=2760]

This model appears to have sunk below the shelf in the cargo container [Map05: x=16/y=6948]

The problem with the model in Map05 might be because of GZDooM, as the model sinks even when played just with paranoid.pk3. [I'm quite sure this problem didn't exist when we play-tested and released paranoid.pk3.]

The first one is not happening on my end. It could be due to different versions of the map. At one point, I redid how these large vehicles handle their collision boxes; instead of having to place the invisible 'blocking' actors around them on the map, the vehicle actor does it automatically via ZScript. Still, thank you for capturing it, and feel free to point out any other anomalies.

As for the second one, I believe you're right; GZDoom has changed how it handles 3D floor collision a few times in the past, and then actors may not fit the same way and they get forced up or down through the floor. If I remember correctly, I can fix this by either tweaking the Z coordinate of the actor in the map, to make sure it's above the floor in question, or by adjusting the actor's height to be sure there's enough room.

Incidentally, here's what I believe to be another example of it from the third map:

Which version are you using? I'll make it a point to use the same version. [I believe I was using v4.10.0; I also have 4.12.2, which has a vintage of April 2024.]

I think that was a brilliant decision, as using invisible bridge things is a huge pain that requires endless trial and error.

It would be excellent if you can fix it at your end, but please wait until I've play-tested the entire set of maps to identify other anomalies (no pun intended).

I must have missed that one.

Thank you for your attention to this matter, Boss.

I'm using GZDoom 4.14.1, released March 1st 2025. I apologize, though, as I was ambiguous; I was referring to what version of Paranoidiac and its maps. My memory is truly awful, but upon checking the Git history, the commit where I redid the bulldozer's collision boxes is from Aug 27, 2018, and is even entitled "Fix the hovering bulldozer". If you're using a version of the maps that predates this, your bulldozers may hover.

No problem, I can wait on it if you'd like. There's surely other things to address in the meantime. I'm doing some testing recently, as well.

I'll switch to that version, as long as it's been deemed stable.

Yes, indeed, I was using the older version. Switching to the most recent version of paranoidiac.zip available on GitHub (the file folder inside the zip is dated 9/4/2019) made the problem go away. Many thanks.

On a couple of unrelated notes:

1. What is the cheat code for switching/warping to a different map? Or, rather, what are the map slots/names I ought to use? For example, using IDCLEV03 takes me to DOOM2 Map03, not Paranoid Map03.
2. I'll put this into a separate thread of "to-do" items, but the sliding doors make no sound. I think this was an omission on my part in Paranoid, which (IIRC) I rectified in Paranoiac.

IDCLEV works if the maps have been given level numbers in mapinfo - up to map99 as I recall.

However, if maps have not been given levelnums, or they have unusual naming conventions, you can use the console.

The two relevant commands are map and changemap.

The map command warps you to the map in the same way as the old cheat code - i.e. you arrive with full health and the default inventory items.

The changemap command takes you to the new maps in whatever state you were when you left the previous map. It is much more like if you had hit an exit switch to take you to the new map - including showing a tally screen etc if that is appropriate for the map transition.

Both of these console commands take the name of the map file (or map lump) as it is found in the PK3.

So, if you have a map in your maps folder of the PK3 called "coolmap.wad"...

map coolmap
that will warp you to the map.
changemap coolmap
that will take you to the map as if you had hit an exit switch that is set up to take you to the new map.

I've named the maps in the convention of Doom. Paranoid, as the first episode of the adventure, is on P1M1 through P1M8. Paranoiac starts on P2M0 and runs through P2M9 for the earthbound maps. Xen maps are P3M1 through P3M3, then the two secret maps are P3M4 and P3M5.

[Enjay]

So, just for belt and braces:

map pXmY

or

changemap pXmY

will work at the console, where X is the episode number and Y is the map number.

[Rex Claussen]

Thank you both for the excellent explanations.

@Ed the Bat: I vaguely remembered your naming convention, but I didn't think of using the console, as @Enjay had suggested.
