GZDoom 3d floors and AI interaction

Ultraviolet · Post by **Ultraviolet** » Mon Nov 13, 2006 8:06 am

Do 3d floors affect how AI navigates the map? I haven't really been able to observe anything yet, but maybe someone here can provide details. One potential concern I have is that there might be issues with AI avoiding 3d floors as if they're non-solid. I suppose I could easily test that in a map, but I'm going to go to bed after this post, and I'd still like to know about any other effects 3d floors have on AI anyway, so the post still serves at least some purpose.

I'm also not clear on how exactly one goes about discussing GZDoom here. I know GZDoom has its own forum, but it is somewhat inactive compared to this one, and I see GZDoom discussed here a lot. I'm not familiar with any official policy, and I've only recently returned here as a regular after a long period of inactivity, so there are many things I'm a bit in the dark on.

The official policy should be that port specific questions are posted in the forum belonging to that port.

Regarding your question, monsters can walk on 3D floors but thanks to Doom's crappy movement code it may produce strange results on occasion. But in normal situations it will work.

although this was the wrong forum for this post, it does raise a question i had the other night. do actors like shell casings on 3d floors require extra processing by the (g)zdoom engine? i made a 3d floor tower and when inside of it shooting my mod's minigun, it begins to lag horribly.

I haven't had any problems with it yet, and my level is full of 3d floors.

Remember, I have tested this with Nimrod and HTH2, both of which use 3D floors everywhere, including lots of places with monsters.

Is there a GZDoom version of Nimrod, or are the 3d floors created the exact same way in-editor?

GZDoom supports all Legacy features to run Nimrod.

Was that written to mean that it supports all Legacy features, or all Legacy features that Nimrod uses?

All Legacy features that Nimrod uses.

Monsters will not cross onto 3D floors if the 3D floor is lower than the sector that the mosnter is on, i think. Atleast that the problem i've been having.

So they won't "Step down" unless you use the DROPOFF flag.

Does DROPOFF let them walk off of high cliffs too, though?

Ayup. Actually now that I think about it, isn't there a max step height thingy? I dunno if that'll work though.

Presumably Eriance is talking about cases where the difference between the 3D floor and the floor the monster is standing on is less than the maxstepheight property of the monster -- otherwise it wouldn't be a bug.

Eriance: Suppose this gets solved... come back to your project?
