What is the issue?

[playzooki]

i dunno, just plays normal sounds, not what was intended

can you paste the relevant section of code?

Ok I'm pretty new to the whole modding scene and so far it looks amazing. I want to create a mod like technic (I know it's a big thing for a newbie but I've always learnt like that) and I'm looking at inventory management. I've looked at the chest lua file and I can understand that formspec is like the GUI library, correct? But I can't get my head around this little bit for the location: list[current_name;main;0,0;8,4;]

What is "current_name", I've seen it used in the furnace also but I just don't know what it is so I can't play with it.

Next question is irrelevant to the previous. I want to create multiblock structure and I'm unsure how multiple blocks can share inventory/information, do the same actions when a person activates it and what not. I think I should be looking at detatched inventory but yet again I'm unsure what it is.

ah, ok, I new I should have looked further down, sorry about that. So anyway, current_name is just saying use the metadata from this node? This also clears up detached inventory, with detached inventory I could create an ender chest or something similar, right?

Thank you for showing me that.

Edit: Just created the ender chest, just created a detached inventory and made the chest code look here instead of metadata.

If there a mod which can stop people from placing buckets?I still want to be able to pick up water and lava but not place it.
And then if people on the server want to place water or lava they can ask me and i will type /giveme water_source and place it where they want it.

If there a mod to disable placing of buckets, or a simple way to remove bits of code?

I think I can, let me have a look through the code, if anything it will be in the bucket's lua file.

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 default.node_sound_rick_defaults(table)
    table = table or {}
    table.footstep = table.footstep or
            {name="rickroll", gain=1.0}
    table.dug = table.dug or
            {name="rickroll", gain=1.0}
    default.node_sound_defaults(table)
    return table
end


minetest.register_node("rickroll:rickroll", {
    description = "You just got Rickrolled!",
    tiles = {"rickroll.png"},
    is_ground_content = true,
    groups = {hot=3, cracky=2},
    drop = 'rickroll:rickroll',
    legacy_mineral = true,
    sounds = default.node_sound_rick_defaults(),
    damage_per_second = 8*2,
})

Pretty much, I need help doing everything on this mod's todo list:

Another question: If I change a node using setnode, is its ondig function called, if not can I call it myself?

Edit: ignore, I found out

Is there any way to load a minetest schematic file directly into a VoxelManip object? ie without actually placing the schematic.

I was wondering if anyone can give an understandable guide on creating a Brewing Screen. I had a plan to make a Cauldron mod with a brewing system that requires 4 items, 1 item is a bottle of water and the other 3 are various items as recipes.

This is the kind of screen I was hoping to build.


Also, I barely understand the lingo the lua guide tells me.

It is pretty easy to make the formspec, but making it functional is another thing entirely. You would need to make an api for making potion recipes, and the potions themselves, as well as making the brewing actually work.

That's what I was worried about. Thanks for feedback though. Perhaps in a future build of Minetest when development needs a new challenge we might see something like this come along.

A good place to look for code is the code for the furnace. Brewing works in a very similar fashion, so it might be helpful.

Thanks, I'll try to breaking it down from there. I may not be able to make the brewing cauldron that I really want, but I have to start somewhere.

Also try looking at the formspec for my Factory in the industry pack, and the code related to that too,it is in the Modding Generalk section right now.

Easy way to animate tool textures while youre holding them in your hand and inventory? Perhaps a really short code of some kind? Will be highly appreciated.

Not possible.

Ohh, dissapointing :(

Hello guys,

i found the following lines within the /builtin/misc.lua:

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 minetest.get_connected_players()
    -- This could be optimized a bit, but leave that for later
    local list = {}
    for _, obj in pairs(minetest.get_objects_inside_radius({x=0,y=0,z=0}, 1000000)) do
        if obj:is_player() then
            table.insert(list, obj)
        end
    end
    return list
end


Wouldn't it be a bit better according to performance if one replaces it with 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

local player_list = {}

mintest.register_on_joinplayer( function( player_ref )
    table.insert( player_list, player_ref )
end

minetest.register_on_leaveplayer( function( player_ref )
    for index, value in pairs( player_list ) do
        if player_ref:get_player_name() == value:get_player_name() then
            table.remove( player_list, index )
        end
    end
end

function minetest.get_connected_players()
    return player_list
end


It needs two more registrations and a seperate table, but we don't force the engine to first collect
all objects within the given distance and then iterate through all these collected objects just to check
if its a player or not. Its possible that im wrong somehow, but i came up with this when i woke up,
so the code is not tested up to now.

You had some typos but it works for me.
And when you consider a server with thousands of saplings on the ground the old method is ridiculous.

Thanks for correcting the code. I needed a bit before i saw them.
