two peculiarities

[ksandronline]

Good time.

I really like your basic_robot mod, I hope you will develop it further and support it.

I noticed a few peculiarities.

1. self. listen_msg () - works only in single-user mode. On the server, I can't use this function.

2. self.set_properties({
   visual = "mesh",
   mesh = "character.b3d",
   textures = {"character.png"}
   })

• when using different meshes, textures are loaded at different "heights".
  If mesh = "character. b3d" - then the robot "hangs" on the floor of the block above.
  And for example mesh = "mobs_spider. b3d", will be on the floor of the block in the ground.
  And this mesh = "mobs_panda. b3d", the robot works correctly.

You have turned out a very interesting mod. I really hope that it will not be difficult for you to solve these features.

in 'HELP' button you can see use: speaker,msg = self.listen_msg(). That means that self.listen_msg returns 2 strings as output. if there was no new chat message it returns nil. So you can use it like:

if not init then init = true self.listen(1) end -- this will run only 1x and make robot start to listen
speaker,msg = self.listen_msg()
if msg then say(string.format("message from %s : %s", speaker,msg)) end

self.set_properties just uses minetest built-in function object:set_properties(object property table). So all problems are coming from there.
