mods in /usr/share/minetest/games/minetest_game/mods override mods in ~/.minetest/mods/minetest.

For example, if I have a mod named 'stairs' in ~/.minetest/mods/minetest/stairs/, my stairs mod will not run, but the default stairs mod in /usr/share/minetest/games/minetest_game/mods/stairs will.

could we get this changed so it checks the world directory first (~/.minetest/worlds/WORLDNAME/mods/), then the per user folder (~/.minetest/mods/minetest/), then the global folder (/usr/share/minetest/games/GAME/mods)?

Also, the stairs mod needs to use minetest.get_current_modname() in it's stairs.register_* functions in order to play nice with other mods.

code like this:

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: -- add glass and desert stone stairs and slabs stairs.register_stair_and_slab( "desert_stone", "default:desert_stone", {cracky=3}, {"default_desert_stone.png"}, "Desert Stone Stair", "Desert Stone Slab") stairs.register_stair_and_slab( "glass", "default:glass", {snappy=2,cracky=3,oddly_breakable_by_hand=3}, {"default_glass.png"}, "Glass Stair", "Glass Slab")

in another mod gives errors like this:

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

here's a modified init.lua that should fix this (maybe... see first bug for why this isn't tested):

Easy fix: use a self-compiled run-in-place version. 8)

Anyway; the folder ~/.minetest/worlds/WORLD_NAME/worldmods always gets checked before ~/.minetest/mods/minetest, which gets checked before /usr/share/games/minetest/games/minetest_game/mods.

Checked that, but it looks like it's the other way around.
I made a mod in ~/.minetest/mods/minetest/stairs with an init.lua like this:

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: print("hello from "..minetest.get_current_modname().." at "..minetest.get_modpath(minetest.get_current_modname()).."!")

and watched stdout.

That code never runs, but if I move it from ~/.minetest/mods/minetest/stairs to ~/.minetest/mods/minetest/mystairs, it does. There were no error messages either way.

Advantages (for me):
- I don't need to sudo for installing mods, so easy to delete and insert mods
- Very easy to make x copies of minetest in your home directory to try out different mods, textures etc.

You would have the same advantages with the world mods and home directory mods overriding the global mods without the need to have multiple copies of minetest itself. You could use different sets of mods by using the per-world mods.

I didn't know that. I sometimes like to try out changes in the init.lua's of for example the minetest_game mods. When I screw up, I've plenty of original init.lua's to restore it, or I just delete the whole folder. I guess I'm compensating my lack of knowledge with disk space :-/

So you dont' need to sudo every time you install a mod? It has been a while ago I used a non-self compiled Mintest.

Btw, I agree with your proposed checking order.

It was close, but not quite right. See http://minetest.net/forum/viewtopic.php?id=2998 for a working mod that fixes stairs.

stairs itself, if modified, would look like this:
