S, I've been working on a mod (duh), and I want to add a custom sound for the block entity when walked on. I did this correctly back in MT 4.11, and it worked (never published the mod so I lost it). I used a small, edited version of the default sound registration, which worked then. I do the same thing now and I keep getting errors that pop up at random times. What I've been trying is:

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all: function pm.node_sound_defaults(table) table = table or {} table.footstep = table.footstep or {name = "pm_block_step", gain = 1.0} table.dug = table.dug or {name = "pm_block_dug", gain = 0.25} return table end

From the debug.txt:

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all: ========== ERROR FROM LUA =========== 2016-03-29 22:31:15: ERROR[main]: Failed to load and run script from 2016-03-29 22:31:15: ERROR[main]: C:\Games\Minetest\bin\..\mods\pm\init.lua: 2016-03-29 22:31:15: ERROR[main]: C:\Games\Minetest\bin\..\mods\pm/sounds.lua:1: attempt to index global 'pm' (a nil value) 2016-03-29 22:31:15: ERROR[main]: stack traceback: 2016-03-29 22:31:15: ERROR[main]: C:\Games\Minetest\bin\..\mods\pm/sounds.lua:1: in main chunk 2016-03-29 22:31:15: ERROR[main]: [C]: in function 'dofile' 2016-03-29 22:31:15: ERROR[main]: C:\Games\Minetest\bin\..\mods\pm\init.lua:1: in main chunk 2016-03-29 22:31:15: ERROR[main]: ======= END OF ERROR FROM LUA ======== 2016-03-29 22:31:15: ERROR[main]: Server: Failed to load and run C:\Games\Minetest\bin\..\mods\pm\init.lua 2016-03-29 22:31:15: ERROR[main]: ModError: ModError: Failed to load and run C:\Games\Minetest\bin\..\mods\pm\init.lua 2016-03-29 22:31:15: ERROR[main]: Error from Lua: 2016-03-29 22:31:15: ERROR[main]: C:\Games\Minetest\bin\..\mods\pm/sounds.lua:1: attempt to index global 'pm' (a nil value) 2016-03-29 22:31:15: ERROR[main]: stack traceback: 2016-03-29 22:31:15: ERROR[main]: C:\Games\Minetest\bin\..\mods\pm/sounds.lua:1: in main chunk 2016-03-29 22:31:15: ERROR[main]: [C]: in function 'dofile' 2016-03-29 22:31:15: ERROR[main]: C:\Games\Minetest\bin\..\mods\pm\init.lua:1: in main chunk 2016-03-29 22:31:15: ERROR[main]: Check debug.txt for details.

I'm not understanding what I've done wrong, so can you help me please?

This means that the (global) variable pm is not defined. You have to define it first, because Lua don't knows the variable and you have only specified a sub-variable (node_sound_defaults).
C:\Games\Minetest\bin\..\mods\pm/sounds.lua:1: attempt to index global 'pm' (a nil value)

Add this at the top:

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all: pm = {}

or if you only want to use the variable in this file then:

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all: local pm = {}

nil equals a None in python, and a NULL in C/C++ and it only means that the variable is not defined.
