Welcome to the ZDoom Forums!

If the lanterns are never meant to teleport and they're not solid, giving them +NOBLOCKMAP should do the trick.

The link you posted gives me a 404 so I can't see what you mean.
Any actor the portal line crosses will teleport, that's intentional.

A minor release with some bugfixing and general refactoring.

Works with UZDoom 4.14.3 and the 5.0 Preview dev builds.

Version 2.5 is out!

- Several under-the-hood changes and bugfixes
- New feature: you can give platforms an arbitrary pivot point to rotate around
- New feature: perpetual rotation/turn speeds to complement the pivot feature
- New feature: platform interpolation points can ...

In case anyone's wondering. I am helping kdoom over on Discord.

Which reads: target.DamageMobj (null, victim, 3, 'Melee');

Should be: victim.DamageMobj (null, target, 3, 'Melee');

Because the syntax for DamageMobj is

Just wanted to give an explanation.

Alright, so the problem is that A_CheckFloor checks the calling actor's floorz value to see if it goes below the current sector's floor or below the lower 3D floor. (As far as I can tell "floorz" never takes into account actors below other actors.)
I don't feel ...

I've fixed the compat_crossdropoff issue with a little hack. I've made a few commits to the repo today.

Have a testbuild and please tell me if the issue is resolved on your end?
EDIT: testbuild removed

Fantastic work! This is incredible.

I think I managed to find one bug tho. On a "on enter" trigger that's set to trigger "true single time" it's possible for multiple actors to trigger it before it disappears. Right now the trigger box only disappears when the triggerer steps away.

In this test ...

This is a minor bugfix/patch release.

(This release now works with zscript version "4.12" among a few very minor fixes.)

I tried to load a map01 in it and it says 3Dplatform v2.2b.pk3:zscript/fishy/platform-base.zs, line 432: Unable to resolve LinePortal as a type.

Change that line from:
LinePortal port = level.linePortals[iPorts];
To:
let port = level.linePortals[iPorts];
That error happens when the zscript ...

Today I learned two things. First, that the old version wouldn't run if choosing DOOM 2: KEX Edition as the IWAD.
And secondly that $musicalias assignments can be undone.

So I'm releasing a v2 version, attached to the first post. This will work with the Doom 2 KEX Edition.
Being able to undo ...

(I hope this is the right sub-forum)

This little PK3 contains the bare minimum SNDINFO lumps that make GZDoom make use of the remix tracks which are inside the rerelease's extras.wad file. The tracks have the H_ prefix as opposed to the usual D_ so just loading extras.wad by itself won't do ...

A quick patch release!

This is the same as v2.2 in addition there's a NOCORPSEGIB actor flag.
It prevents gibbing corpses when touching them. Useful for platform-monsters. (Like that cyberdemon.)
