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

--state=true: lay, state=false: stand up
local function lay_down(player, pos, state)
   local name = player:get_player_name()
   if not player or not name then
      return
   end

   -- stand up
   if state ~= nil and not state then

      -- physics, eye_offset, etc
      player:set_eye_offset({x = 0, y = 0, z = 0}, {x = 0, y = 0, z = 0})
      player:set_look_yaw(math.random(1, 180) / 100)
      default.player_attached[name] = false
      player:set_physics_override(1, 1, 1)
      default.player_set_animation(player, "stand" , 30)

   -- lay down
   else
      player:set_eye_offset({x = 0, y = -13, z = 0}, {x = 0, y = 0, z = 0})
      local yaw, param2 = get_look_yaw(bed_pos)
      player:set_look_yaw(yaw) <you still need to implement that function that tells you in which direction the player should look when laying>
      local dir = minetest.facedir_to_dir(param2)
      local p = <position where the lay-thing is>
      player:set_physics_override(0, 0, 0)
      player:setpos(p)
      default.player_attached[name] = true
      default.player_set_animation(player, "lay" , 0) --that does the trick with laying the player down
   end
end


These are the relevant lines from beds mod. You need to add some stuff yourself.

[Icalasari]

Is it possible to have a node that consists of two blocks each referencing their own textures? e.g. a jar that is x1=-4,y1=-8,z1=-4,x2=4,y2=2,z2=4 and is like the drawtype glasslike, with an inside that is x1=-3,y1=-7,z1=-3,x2=3,y2=1,z2=3 and is like the drawtype liquid (using NodeBoxEditor hence the 16x16x16 coords)? Or would the inherent nature of NodeBox make it not work?

If you want that kind of "complex" shape, you will need to create a model for it using e.g. Blender, and use the "mesh" drawtype.

Hi all and thanks advance , i make my new mod named summer i have put :
big umrella open and closed ,deckshair, lobster, big ballon ,air mattress etc...
now i need a little help for add simple function sit or lay on_rightclick ,
but but I found nothing on internet,
i have see beds but can only sleep, and boat are mixed with driver function , i have registered a node and i want the player can lay on the node with right click pls Help
sorry for my bad english

some help?

you could make something 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

on_right_click = function(clicker)
if sitter then
sitter:set_animation(stand)
else
sitter = clicker
sitter:set_animation(sit)
end
end


(its not really correct, i think...)

Sokomine's Cottages mod, https://forum.minetest.net/viewtopic.php?id=5120, has a bench and a couple of beds that allow sitting or laying on right click.

[Icalasari]

Well I'm starting to get the hang of things (decided to leave meshwork for later and go a different style route for the node), but I hit a snag

Can nodeboxes have animated textures? Because I tried, with this being the intended result

Instead I got this jar of nope (which I am definitely going to recreate - Planning on two focuses that would split into mod packs, one being a magic and potions mod pack)

Trying to figure out where I went horribly, horribly wrong. Can somebody look at it and see where things are glitching out, please?

ps: nice texture!

[Icalasari]

@DS-mintest

Thanks - Still wondering how it screwed up the texture to that degree. Glad to also find out I can cut repeating that three additional times for the same texture

And also thanks on the compliment - I used to do a lot of sprite art, and got a lot of practice when I did the Harvestmooncraft texture pack. Trying a cel shaded style to go with these mods I'm making

[Icalasari]

Is there a way to include more information in the tooltip? Looking it up seems to point to no, but I could be missing something

[AnxiousInfusion]

How do you register a tool (sword) and give it an on_use function without overriding it's original function as a sword?

[D00Med]

^I'm interested to learn that too

[azekill_DIABLO]

look at farming mod: the hoe does same.

[BirgitLachner]

I have two questions:

1.) Where do I get all the name of the default object from? Where do I have to look?

2.) Any hint how to use an object like a bucket? I only found a group for a filled bucket.

1. default object?
2. take a look at https://github.com/minetest/minetest_ga ... t/init.lua

[BirgitLachner]

Ah, yes ... a "s" is missing. I mean default-objects, like stone, sand ...

Since I got help here with my air rosin, I thought I'd post the finished code for everyone; as a thanks.

      if pointed_thing.under then -- check if it is a node/exists (needed)
      
         -- keep this low, the bigger the # the longer the loop
         local final = 3 -- size of area to delete (+-3 in all directions)
         
         local target = minetest.get_node(pointed_thing.under) -- target node to delete
         local pos = pointed_thing.under -- position of pointed node, centralizes the love

         end
      end
   end-- so many ends, the plot thickens.

I've tested that it works, just need an image and a mod folder. It clears out nodes nicely, great for deleting forests. Haven't packaged it into a mod because I'm working on a modpack with scripts for specific things. I'm sure you guys are smart enough to either use it, or learn from it.

Questions:
I have a node that gives copper lumps when right-clicked, unless you are holding copper lumps. What would cause that to happen?
How would I drop an item stack entity that could be picked up?

[Havocado]

Is there a way to make an item that drops itself when broken by hand, but drops a different item when broken with the proper tool?

[PlanetKiller]

Is there a way to make an item that drops itself when broken by hand, but drops a different item when broken with the proper tool?

use get_wielded_item()

if it = a specific item, drop one item
else, drop another.

Not sure how it would exactly work, but that's the best I can find with my skill.

Trying it, but getting errors.

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_dig = function(pos, node, digger)
   print(digger)
   print(digger.get_wielded_item(digger).name)
end


Tends to either print nil or userdata: 0x00f84510
Tried using .name and .get_name and several crashy variations.
(the block keeps reloading when I break it, but I'm missing a drop so...)

I know I am late to this.... but I think you might have just wanted one of the default minetest functions 'minetest.get_nodes_in_area": http://dev.minetest.net/minetest.find_nodes_in_area

I actually made a similar tool which I use for clearing large swathes... and it's very useful for putting out fires that have spread over a forest area for a while....

[everamzah]

minetest.handle_node_drops

If the node is what you want, parse the drops and give to player appropriate item per currently wielded item? (get_wielded_item)

[everamzah]

How do you register a tool (sword) and give it an on_use function without overriding it's original function as a sword?

If I remember correctly, this is not possible. I only say that because I tried it myself first, before giving up and using minetest.register_on_dignode instead. In my mind, I would think it possible, but cannot imagine how.

Edit: I think I meant minetest.register_on_punchnode!

Edit2: I assume only defining on_use would be a problem, and that on_secondary_use, or on_rightclick can be used instead, if that would suit your needs.

[AnxiousInfusion]

Thanks, even though that is sad news. I got 90% of the way through making a sword with dynamic sound effects only to get snagged on the on_use override. Maybe I can have it set_hp() if pointed_thing is an object ... object.is_player() ... ?

I really wish the engine had some sort of register-damage function.

If the pointed_thing holds an ObjectRef (and you call it obj), call obj:punch in your on_use (documented on line 2580 of lua_api.txt, I think?) to simulate the original punching that a sword does. This will still prevent you from digging with the sword, though. I think this mod had some examples of punching from on_use: viewtopic.php?f=11&t=14937

I've been trying to do this too; unfortunately it does not look possible.

What are you trying to achieve, maybe we can look into that?

If you don't care about digging functionality, I described how you might retain punching functionality in my previous post. If you want to be able to dig though, you could use a register_on_punchplayer callback for your punch effects instead, though it wouldn't your special stuff if you punch a lua entity rather than a player.
