ZDoom

Have you considered using Visual Thinkers?

A Quake source port (probably encompassing features from Q2 and Q3 as well) with the moddability oz GZDoom would be a dream. With the way Quake engine games load mods, you can't get teh incredibly flexibility that ZScript and the stacking of mods offers.

Still strange that it worked in earlier GZDoom versions. Oh well. I have plans to make an "official" library out of this with Ash's help.

Loks like some of the newer GZDoom versions broke the mod. I tested it with 4.3.3. and it works flawlessly. A bit of progress... maybe (I'm really just taking wild guesses to see if anything works). If I comment out this line in the Pastebin code: smtActor.SetOrigin(tempPos + dir * smtActor.speed ...

Sorry, I forgot I only posted the code instead of the archive.
I added a link to the pk3 in my first post.

Stand alone archive? The only one I can see is linked to here : https://forum.zdoom.org/viewtopic.php?p=1151905#p1151905 and the file has gone. Is there another? I've searched here, Doomworld and via Google. I don't see one in the VoxelChibiDoom thread, and the link there just takes me direct to ...

No, in the standalone archive.

Note that in VoxelChibiDoom!, the very first time ChaseSmooth is called, it uses the actor's orignal speed value specifically to avoid monsters in vanilla Doom maps getting stuck if placed near walls.

There's also code for an altered Zombieman using SmoothMoveTurn included in the archive.

I have used the smooth moving / turning code in almost all my mods and for some reason never encountered these problems... Not sure what to say. I didn't test it extensively with slops, though. Maybe slope traversing becomes a problem when the speed is very slow, as with your robot.

Not sure what to tell you. If you want to limit the turn speed, you set smtTurnSpeedMax from aynwhere.
It can get set when calling InitSmoothMoveTurnMixin in PostBeginPlay() and is set to 0 if you don't pass a value for turnSpeedMax.

Set smtTurnSpeedMax to 15 or something.

Keep in mind that the actor's speed value needs to be set equal to [original speed / movement tics], otherwise monsters are far too fast and might have trouble navigating. Also, for vanilla Doom maps, a lot of monsters have spawn locations that make them move into walls and get stuck the very first ...

Override the monster's PostBeginPlay and call InitSmoothMoveTurnMixin(self,5,5);
Override the monster's Tick and call Super.Tick() and UpdateSmoothMoveTurn();

Add mixin SmoothMoveTurnMixin to monster actor.
Call ChaseSmooth() instead of A_Chase.
