#(_seppy_) Oddly specific pathing bug

An NPC with attributes:

  • GENERIC_STEP_HEIGHT 0.1
  • GENERIC_JUMP_STRENGTH 0

Can actually jump up a whole block if a Trapdown is placed on the floor, and clicked once to change the state of the trapdoor to vertical

To reproduce:

  • Step 1: Place trapdoor on floor
  • Step 2: Make the trapdoor stand up
  • Step 3: Enable wander pathing on NPC
  • Watch it walk up a whole block height and escape the enclosed area

My guess is that 0.1 is the trapdoor height, but the pathing doesn't take the trapdoor other state into consideration, and only looks for the original state of the trapdoor

Seems to be super inconsistent too, not always reproduceable from my testing

#
  • Is it possible that NPC pathing can start messing up if my server is running super low on RAM?

#

I'm also noticing some skins not loading, even though they are hosted locally using --file

#

Hypothetically... 100 NPC's, 50 of them are moving with wander, and the server has 3 GB ram. The server itself is using all the ram, but it's not lagging, however, can this cause issues with Skin loading and Pathing?

Possibly Relevant Plugin(s)

HeadDatabase v4.20.2 - HeadDatabase has been known to cause issues with skins.
CMI v9.7.6.3 - CMI tends to mess with a large variety of server features and often gets in the way of issue debugging.
ModelEngine vR4.0.7 - ModelEngine has Citizens support, but that support is known to be buggy. Issues related to NPCs that use ModelEngine should be reported to ModelEngine support, not Citizens.
Multiverse-Core v4.3.13 - Multi-world configuration plugins may affect NPCs in unexpected ways.
FastAsyncWorldEdit v2.11.3-SNAPSHOT-916;7daafa9 - This plugin has been known to break the plugin load order on many servers, due to usage of the 'loadbefore' directive in its 'plugin.yml'.

Potentially Bad Line(s)

Starting Minecraft server on *:25612 - server is offline but has no address bind. This might mean you're using a system level firewall, but if not, it means your proxy is bypassable by hackers. Either enable a system level firewall, or bind your server to localhost in server.properties via server-ip=127.0.0.1.

step height is reset to 1 on spawn

#

@narrow trellis firstly; is this related to respawn persistence?

narrow trellis
slate mason
narrow trellis
#

Yes

slate mason
#

NPCs spawn every time a chunk reloads or a server loads

narrow trellis
#

Ohh, didnt know that

slate mason
#

yes, they need to be spawned in

narrow trellis
#

I believe the answer is yes then

slate mason
#

ok there just needs to be some extra code then

#

can fix this today

narrow trellis
#

Sweet!

slate mason
#

@narrow trellis can you try in the new build

narrow trellis
#

Testing now

narrow trellis
#

And they arent coming back, even if i keep doing /citizens reload

#

Also I'm only using --file skins if that matters

slate mason
#

@narrow trellis no, build 3575

narrow trellis
# slate mason <@289942152308588544> no, build 3575

Seems to fail to load the skins half the time when i do /citizens reload, but if i go far away, and return to make them "respawn" they fix themselves majority of the time

As for the other issue (attributes) i havent tested yet

slate mason
#

@narrow trellis ok please test the other issue

narrow trellis
slate mason
#

ok, if you are having issues with seeing skins then open another thread

#

enable debug mode and post logs in that thread
