AsyncErr: ServerThread::run Lua: Runtime error from mod 'mobs_flat' in callback luaentity_Step() #62

Closed ghost closed 4 years ago

Game crashes with 'an error occurred' screen after about 30 seconds. it doesn't seem to matter what I'm doing; really just jumping and walking around. The error is

AsyncErr: ServerThread::run Lua: Runtime error from mod 'mobs_flat' in callback luaentity_Step(): /home/user/.minetest/games/voxelgarden/mods/mobs/api.lua:136: attempt to index a nil value
stack traceback:

    /home/user/.minetest/games/voxelgarden/mods/mobs/api.lua:2981: in function </home/lane/.minetest/games/voxelgarden/mods/mobs/api.lua:2815>

Sometimes it crashes with this different, but similiar error:

AsyncErr: ServerThread::run Lua: Runtime error from mod 'mobs_flat' in callback luaentity_Step(): /home/lane/.minetest/games/voxelgarden/mods/mobs/api.lua:147: attempt to index local 'v' (a nil value)

Same error (2nd one) here. Running v7, minetest 5.2, ArcoLinuxB 5.6.2-arch1-2. Happens a few seconds after start, even when I don't touch anything at all.

This was fixed in the original mobs redo mod. Since "mobs" in VG is just a trimmed down version of it I copied the latest code. For me it works now. Would be good to hear some others confirming it.

I just copied api.lua, api.txt from https://notabug.org/TenPlus1/mobs_redo/ and error is gone.
