Can someone explain me what is wrong on this mod ?

you forgot to add a "dofile" to the api.lua at the beginning of the init.lua so the mob is defined. It should fix the problem. By the afternoon I will test. :)

Example:

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

dofile(minetest.get_modpath("slender").."/api.lua")

minetest.register_node("slender:slenderwater_flowing", {
   description = "Flowing Fear",
...


EDIT:

what is api.lua good for?

The api is the monster(mobs api) its purpose is to define the slender mob.

EDIT2: I took a look at the textures, that slenderman sprite looks good! :D

[AMMOnym]

It was gif :)
Thanks Esteban

Code: Select all

on_use = function(itemstack, user, pointed_thing)
      local playerpos = minetest.player:getpos()

Use the given 'user' variable.

Is any way, how to make an invisible water ?

[DeepGaze]

textures, or do you mean whilst you are inside?

Just textures. When I use an invisible texture, its white or black ...

No, I mean something like this

Is there any way for an admin to check a users IP using a command on servers? It would be quite helpful if there was in the case of account theft...

minetest.register_chatcommand("get_ip", {

})

this could work

some time ago my account got stolen by someone and the admin didn't care
Krock was on bloster's server, too

[Linuxdirk]

I wonder how the IP address will help on server account theft since IPs are usually randomly assigned by the ISP.

Well, usually bad guys cannot stole IP from original account creator, so in some cases it is possibe to find out who account belongs to.
But personally i think that this is not admin work to solve players weak passwords problems. This is great lesson for players about password importance. When loosing game acount, they probably will care about setting good passwords at work, for bank card etc.

Topic: What is the default block size when modeling in blender?
Reason: I'd like to make models and I wanted to size them correctly

In my experience it's a cube that is 1 blender unit tall, wide, and deep.

[philipbenr]

Verified. A 1x1x1 cube is the size of a node in Minetest.

Now for my own question: How would bumpmapping for a meshnode be done? Is there a way in Blender? Or in Minetest? Or neither?

[Linuxdirk]

Is there a way to add text to the HUD like the Minetest version information in the top left corner? Or is there a way to alter that text without changing the source code and re-compile it?

bump mapping is done via textures, it should in blender, just to see what it would look like, and then you'd export your bump map, and use that as a texture in your mod/texture pack. I'm not sure exactly how the engine knows what to use as the bump maps, I'd look at one of the texture packs that have bump mapping to see how they call them out. I'm guessing it's either a prefix or suffix.

See player:hud_add.

Example:

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_on_joinplayer(function(player)
  -- Delay a bit.
  minetest.after(1, function()
    player:hud_add({
      hud_elem_type = "text",
      -- Hud position.
      -- {x=0, y=0} -> top-left
      -- {x=1, y=1} -> bottom-right
      -- etc.
      position = {x=1, y=0}, -- top-right
      alignment = {x=1, y=1}, -- Align top-right.
      text = "asdf",
      number = 0xFFFF00, -- Color as 0xRRGGBB
    })
  end) -- after()
end) -- on_joinplayer()


[Linuxdirk]

See player:hud_add.

I created a mod with only your example in init.lua.There is no text at the top right and I’m not seeing any error messages.

Whoops! My bad.
The `alignment` line should be:

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

alignment = { x=-1, y=1 },


1 means align to left/top, -1 means align to right/bottom, 0 means center, etc.

You may also want to add 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

offset = {x=-8, y=8 }, -- Shift 8 pixels to the left, and 8 pixels down.


[Linuxdirk]

Ah, now that’s something I can work with! Thanks! :) Is there a way to change the text (altering or remove/re-set)?

[kaeza]

Ah, now that’s something I can work with! Thanks! :) Is there a way to change the text (altering or remove/re-set)?

Sure. But for that, you must store the value returned by `hud_add` somewhere, then do the following:

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

player:hud_change(hud_id, "text", "qwerty") -- "qwerty" is the new value for the "text" property.

[Linuxdirk]

Thanks!

Last question: What is the best way to trigger an event every X minutes? And does this HUD text thing work on servers, too?

[rubenwardy]

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 doEventThingy()
    -- do some code
    minetest.after(doEventThingy, mins * 60)
end
minetest.after(doEventThingy, mins * 60)

I suggest renaming the function here.
Also replace mins with number of minutes.

[Linuxdirk]

You guys are awesome!

Thanks again!

[fireuser]

i'm struggling with minetest map gen. I would love it if some one could help me with making land flatter. I've seen it totally flat,but i don't like that. so if you could help me with this,i would be so grateful. Thanks!

[Superdude44]

thanks for the help. I had another question however

Question: when modding a new block to open a gui similar to the chest or furnace, I ran into some problems. I first tried a similar approach to the default chest formspec, but as much as I tried It would not work. I decided to see if I could get it to work with the exact same code for the chest, but use my own nodes. That did not work either. It lets me in game now, but the gui does not pop up. I guess my ultimate question would be how I would get that to show up?

+ Spoiler

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

default.townblock_formspec =
   "size[8,9]"..
   default.gui_bg..
   default.gui_bg_img..
   default.gui_slots..
   "list[current_name;main;0,0.3;4,1;]"..
   "list[current_player;main;0,4.85;8,1;]"..
   "list[current_player;main;0,6.08;8,3;8]"..
   default.get_hotbar_bg(0,4.85)

minetest.register_node("aoe:townblock", {
   description = "TownHall",
   tile_images = {"aoe_lumber_side.png", "aoe_lumber_side.png", "aoe_lumber_side.png", "aoe_lumber_side.png", "aoe_townblock.png", "aoe_townblock.png" },
   groups={snappy=1,choppy=2,oddly_breakable_by_hand=2,flammable=3},
   legacy_facedir_simple = true,
   is_ground_content = false,
   sounds = default.node_sound_wood_defaults(),
   on_construct = function(pos)
      local meta = minetest.get_meta(pos)
      meta:set_string("formspec",default.townblock_formspec)
      meta:set_string("infotext", "TownBlock")
      local inv = meta:get_inventory()
      inv:set_size("main", 8*4)
   end,
   can_dig = function(pos,player)
      local meta = minetest.get_meta(pos);
      local inv = meta:get_inventory()
      return inv:is_empty("main")
   end,
   on_metadata_inventory_move = function(pos, from_list, from_index, to_list, to_index, count, player)
      minetest.log("action", player:get_player_name()..
            " moves stuff in chest at "..minetest.pos_to_string(pos))
   end,
    on_metadata_inventory_put = function(pos, listname, index, stack, player)
      minetest.log("action", player:get_player_name()..
            " moves stuff to chest at "..minetest.pos_to_string(pos))
   end,
    on_metadata_inventory_take = function(pos, listname, index, stack, player)
      minetest.log("action", player:get_player_name()..
            " takes stuff from chest at "..minetest.pos_to_string(pos))
   end,
})

I placed the code in a spoiler to avoid clutter.
Reason: I want to try to figure out more about formspecs.

[Linuxdirk]

you must store the value returned by `hud_add` somewhere

And how to get that value? All I always get is 0 when putting player:hud_add[…] in a minetest.debug().

A simple hud_id = player:hud_add[…] seems not to be correct.

If I try to use that it crashes with attempt to index global 'player' (a nil value) for the line containing player:hud_change().

Complete code:

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_on_joinplayer(function(player)
    -- Delay a bit.
    minetest.after(1, function()
        hud_id = player:hud_add({
            hud_elem_type = 'text',
            position = {x=1, y=0},
            alignment = {x=-1, y=1},
            text = 'First text',
            number = 0xFFFFFF,
            offset = {x=-4, y=4}
        })
    end)
end)

function changeText()
    player:hud_change(hud_id, 'text', 'Changed text')
    minetest.after(5, changeText)
end

minetest.after(5, changeText)

Properly displays “First text” in the top right corner and crashes after 5 seconds with the following message:

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