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

-- ...
on_use = function(...)
  local idx = player:get_wield_index() + 1

  if idx < 8 then
    local inv = player:get_inventory()
    local stack = inv:get_stack("main", idx)
    -- do something with stack
  end
end,
-- ...

Thank you kaeza, that is very helpful!

Don't know if this is a bug in the engine or if I'm doing something wrong.

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

    on_rightclick = function(pos, node, clicker)
        local inv = clicker:get_inventory()
        inv:add_item("main", "pots:pot")
    end,


This should place the item in the players inventory. It works unless the first free slot in the inventory is the players bare hand, then nothing gets added.

I think it is a bug with the engine. The default hand is actually a tool that is named ":"

Hmm somehow I can't reproduce this problem. It gives me unknown item (cuz not known node), tried with wieldhand, cobble and a wooden pick...

EDIT: only works if meta string "formspec" is not set.

I'm trying to make certain I really understand how Pointed_Thing works.

Am I correct that pointed_thing.above doesn't actually mean the node UP from where you are pointed, and pointed_thing.under doesn't actually mean the node DOWN from where you are pointed.
Pointed_Thing.above is the node where an object would be placed, and Pointed_Thing.under is the node that would be dug.
So if I'm pointing at the top face of a node, then .above would actually be the node up and .under would actually be the node under. But if I was pointing at a side face of the cube, then pointed_thing.above would be the node OUT from the face I am pointing at while pointed_thing.under would be the node behind the face I am pointed at.

Or, to put it more simply, pointed_thing.above is always the node in FRONT of the face that the pointer is on, relative to the pointer. And pointed_thing.under is always the face BEHIND the face that the pointer i son, relative to the pointer.

Right, wrong? Somewhere in-between? :)

[Casimir]

Right. (As far as I know.)

[Krock]

@Kilarin: let's use dirt as example node/block.
pointed_thing.under is when you're pointing on a dirt node.
pointed_thing.above is the where the new dirt would get placed normally

[Kilarin]

Thank you Casimir and Krock. That helps. At first I found Pointed_Thing.above and below VERY confusing because I was interpreting "above" as actually UP and I couldn't figure out how the code knew which face you were pointing at from that information. This makes much more sense.

You should use minetest.get_pointed_thing_position to find the position of a pointed_thing
To determine exactly which face you are pointing at see micronode:get_node_normal(pointed_thing) in my micronodes mod.

Does anyone know the mod where you break the bottom of the tree block and the whole thing falls. Do you know where that is and if you do can you put a link down?

It's called timber mod

Need a link? Here is it

[JPRuehmann]

I know of three such mods,
nt (new Timber)
timber
tree_capitator (which I use so far).
look for them in the Forum.

[DeepGaze]

things I want to learn:
how to control the movement of an entity
how to teleport a player after touching a node(to a controlled location)
how to be lord and ruler of all creation
some of this is a priority!

[kaeza]

how to control the movement of an entity

Try looking at Simple Mobs and/or MOBF. Simple mobs have (obviously) simpler movement patterns (simple "set direction and speed"). MOBF on the other hand, has this in addition to using pathfinder.

how to teleport a player after touching a node(to a controlled location)

local admin = minetest.setting_get("name")
local locked = minetest.setting_get("lockdown")

minetest.register_on_prejoinplayer(function(name, ip)

whether lockdown = true or false seems to make no difference

I do have some more questions:
how to substitute the ({x = 0, y = 0, z = 0}) with a chat command

Hi everyone!
While creating a new mod following problem occurred:

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[ServerThread]: Map::setNode(): Not allowing to place CONTENT_IGNORE while trying to replace "traps:acid" at (0,2,-6) (block (0,0,-1))

AFAIK this message appears if a node is not defined or not correctly, but I've no idea what I've done wrong, so please help me! [^_^]
Here is the part of node definition where I think the code is wrong:

no see this for an example, its from my aniwool mod and works fine so you should be ok. though i would space them out a bit(new line)

is it posible to put a texture for each side like this: (say, for a stone node)
and for the other side (blue=north, red=west, yellow=top, ECT) and if so *Can I have some code**pretty please!*
