How do you use get_player_control()?
I try to use it but it gives me nothing.
for example, when I do 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

minetest.register_globalstep(function(dtime,player)
          for _, p in ipairs(minetest.get_connected_players()) do
                     controls = p:get_player_control()   
                     minetest.chat_send_player(p:get_player_name(), #controls)
           end
end)


It displays "0" for the size of controls. So where is my mistake?
I could use get_player_control_bits (at least it sends something about the pressed keys) but I don't really know how to use its bit structure.

The table returned by get_player_controls() is not indexed by numbers, so its 0.
Try print(dump(controls))

How would I go about clearing a formspec? Also, where do I name the formspec in the registration. Code for registration:

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 meta = minetest.env:get_meta(pos)
            meta:set_string("formspec",
                "size[8,9]"..
                "button[0,0;2,1;empty;Empty Trash]"..
                 "list[current_name;main;3,1;2,3;]"..
                 "list[current_player;main;0,5;8,4;]")
                meta:set_string("infotext", "Trash Can")
            local inv = meta:get_inventory()
            inv:set_size("main", 8*4)
        end,

How can I make a texture for my mod have sides, like a chest or furnace? like:

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

tile_images = {"chest_top.png, chest_side.png,chest_front"}

-Thanks in advance

[Dan Duncombe]

Get the six pictures, for the different sides. Then, list them in the order of top, bottom, side, side, side, front. E.G

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

tile_images = {"block_top.png, block_side.png, block_side.png, block_side.png, block_front.png"}

Including 'front' etc is not necessary in the image names.

I had to find it out my self :P
but
You forgot to put quotes:

Code: Select all

tile_images = {"block_top.png", "block_side.png", "block_side.png", " block_side.png", "block_front.png"}

Notice: I put the quotes between each image^

The docs are here: https://github.com/minetest/minetest/blob/master/doc/lua_api.txt#L1676
Translated to layman terms, the order is top, bottom, right, left, back, front.
Edit: Note also that `tile_images' is deprecated; use `tiles' instead:

tiles = {"block_top.png", "block_bottom.png", "block_right.png", " block_left.png", "block_back.png", "block_front.png"}

            inv:set_size("main", 8*4)
        end,


For formspecs associated with node meta, the formname is rarely (if ever) needed.

Ah ok. Then how do I clear the formspec?

[kaeza]

Ah ok. Then how do I clear the formspec?

What do you mean?
Clear the inventory?
Remove the formspec?

[JBR]

If you have a player(objectref) stored in a variable, when that player leaves with the value of the variable become nil?

Clear the inventory of the formspec. :P

Untested code:

Code: Select all

local inv = meta:get_inventory()

  inv:set_stack("foo", i, nil)

Okay, then what do I replace "foo" with?

[kaeza]

Okay, then what do I replace "foo" with?

The inventory list name. from your code, it seems to be "main".

Okay. It works, but I tried changing "main" to "trash", and it messed it up. Thanks though!

Nope.

You must also modify the inventory name in the formspec (and in the set_size() call).
NOTE: Only for the "current_name" inventory!

How I make nodes work like signs? it's just in my Danger signs mod they turn out like dfeault node... help?

I did that, and the player inventory showed fine, but the trash formspec (except the button) is invisible.

Is there any way to alter the node definition values on the fly? For example, if I wanted to smoothly transition a node's alpha using a node timer. Is such a thing possible?

Not currently, other than defining a bunch of nodes with different alpha values, and switch them on the fly.

how do i make lava torches?
like
nnn
nln
nsn

n - nothing
l - lava
s - stick

or how do i do it?

Ehm..... I dont think this question belongs in this topic.

I know this isn't related to modding, but what is the limit to the amount of days/votes that there can be in a poll on the minetest forums? I keep getting an error about it when I try to post.

[Evergreen]

Also, how would I go about detecting a dropped item on top of a node, and if detected, delete it?

[Dan Duncombe]

Are dropped items counted as entities? If they are, might that help?

[Evergreen]

Yes they are entities. I already knew that. :P

I've got some code I'd like to execute whenever a certain type of node is added to the world, including when starting / playing / connecting to the game. Node definitions have lua functions for when hooking to events, for instance on_construct which seemed to most likely candidate, but that doesn't work. Is there some way to do this?

on_construct is only called when the node is placed. Unfortunately, what you require is not so easy (if even practical) to implement.

Edit: I assume you mean the code is run *only* once after connecting. Am I mistaken?

I wasn't very clear, sorry. Yeah, I want it to run once, but probably just when the game / server starts. I don't think I need it for all connecting / joining. I would've thought there'd be some kind of mapping / node creation process that occurred which I'd be able to link into...

Still, I gonna try and use register_on_joinplayer or register_on_newplayer and a find_nodes_in_area. I don't think it's the "right" answer, but it might work.

Oh, on that note, what is the difference between register_on_joinplayer and register_on_newplayer? The wiki isn't very clear about it.
