[Mod] Delete unknown blocks and objects [1] [clean]

[PilzAdam]

Hello everyone!
This is a very simple mod that deletes unkown blocks and removes unkown entities. Just insert there names in the tables in the first two lines and they will be removed when a player is close to them.

Depends:
nothing

Anyway, here is the init.lua:

Code: Select all

local old_nodes = {"mod:a", "mod:b"}
local old_entities = {}

for _,node_name in ipairs(old_nodes) do
    minetest.register_node(":"..node_name, {
        groups = {old=1},
    })
end

minetest.register_abm({
    nodenames = {"group:old"},
    interval = 1,
    chance = 1,
    action = function(pos, node)
        minetest.env:remove_node(pos)
    end,
})

for _,entity_name in ipairs(old_entities) do
    minetest.register_entity(":"..entity_name, {
        on_activate = function(self, staticdata)
            self.object:remove()
        end,
    })
end

Feature request: renaming/migration

Say when you change the name of your mod, or the node, that you could do something like

Code: Select all

nodeswitch('teacup:teacup','tea:cup')

example use: i have a map that uses staircase, which ive updated and renamed since then to nbu, along with some of the nodenames. I cant switch the old mod for the new mod without ruining my map and i dont want to remove the UB's, just switch 'em :-)

From lua-api.txt

Code: Select all

minetest.register_alias(new_name, old_name)

After that you can use both in code and game, new_name and old_name.

How to use?

local old_nodes = {xpanes:pane} does not work

[PilzAdam]

How to use?

local old_nodes = {xpanes:pane} does not work

Code: Select all

local old_nodes = {"xpanes:pane"}

[xyz]

How to use?

local old_nodes = {xpanes:pane} does not work

That will not work, to remove panes you should do it in such way:

Code: Select all

local old_nodes = {"xpanes:pane_1", "xpanes:pane_2" [and so on] "xpanes:pane_15"}

Good job on this mod. Came in really handy this morning as I'm resurrecting an old server and tossing out old mods that has been resulting in a load of orphaned nodes. As long as you keep track of the console window to get the name, it's a snap to add them to the init.lua, bump the server and away the blocks go.

I'm trying to remove the animals mod as it keeps crashing minetest, I've already removed the mod folder. I try running this mod with the following line

Code: Select all

 local old_nodes = {"animal_vombie:vombie","animal_dm:dm","animal_big_red:big_red","animal_chicken:chicken","animal_clownfish:clownfish","animal_cow:cow","animal_creeper:creeper","animal_deer:deer","animal_fish_blue_white:fish_blue_white","animal_gull:gull","animal_sheep:sheep","animal_wolf:wolf"} 

But this doesnt seem to be working, am I missing something?

[cornernote]

use old_entities for animals.

Code: Select all

local old_entities = {"animal_vombie:vombie","animal_dm:dm","animal_big_red:big_red","animal_chicken:chicken","animal_clownfish:clownfish","animal_cow:cow","animal_creeper:creeper","animal_deer:deer","animal_fish_blue_white:fish_blue_white","animal_gull:gull","animal_sheep:sheep","animal_wolf:wolf"}

Can you post your first 2 lines of the init.lua?

Caught it upon examining the back up. Deleted one of these guys --> }

[PilzAdam]

Code: Select all

local old_nodes = {"snow:dirt_with_snow", "snow:snow", "snow:ice"}

for _,node}
local old_entities = {_name in ipairs(old_nodes)

You messed it up a bit :-)
Here are the correct first 8 lines:

Code: Select all

local old_nodes = {"snow:dirt_with_snow", "snow:snow", "snow:ice"}
local old_entities = {}

for _,node_name in ipairs(old_nodes) do
    minetest.register_node(":"..node_name, {
        groups = {old=1},
    })
end

Edit: Deleted old posts, thanks PilzAdam

[socramazibi]

Thanks, I found it very useful.

Can you upload this to your dropbox or somewhere that actually works :-)
