Some questions:
1) Is it possible to create colored light? (e.g. red, blue, green)
2) Is it possible to force a fencelike block to connect to other not fencelike blocks?
3) How can I find out how much performance a mod needs? f5 and f6 show lots of information. Where can I look up what it means?

1) Discussed a lot be4, answer stayed at No.
2) Maybe - extend the collision block to a regular node and look if it works
3) Idk. add os.time()-things like in serval mapgens to see how much miliseconds it takes

[Casimir]

I want to spawn particles when eating something (the way it looks in minecraft). But it uses the whole texture of the item. How can I only use parts of it like when digging something?

2) Is it possible to force a fencelike block to connect to other not fencelike blocks?

There is a fence mod somewhere that does that, but it is somewhat hacky.

2) Is it possible to force a fencelike block to connect to other not fencelike blocks?

Yes, look at XDGAMERZzZ skyblock map. One of the mods in the mod zip file is called fences and I have seen these do this.

[Topywo]

1) Is it possible to create colored light? (e.g. red, blue, green)

- You can make colored air nodes with drawtype airlike and give them a post_effect_color
- Then you change the air around a lightsource that has been placed into a colored air node. While placing the item or through an ABM

Problems:
- When you want to be able to put lights on and off and when removing the lightsource, you'll need to change the air around it (back).
- How to handle the colored air around two different colored lightsources next or near each other (and three and when removing one...)



Edit: At least one typo

[philipbenr]

@RHR. There are two fence mods.
One is xfences, made by xyz (google "minetest xfences")
The second is fences by Blockmen (google "minetest fences")
xyz's is much more reliable than Blockmens, mainly because with Blockmens, some do not connect fully. So, if xfences is still around and downloadable, take a look. I believe that both are hacky, and neither will be of much use if you wish to have it simple. PM me if there is no copy of xfences avail. I might still have a copy

Do anyone like make a Game mode with me?
And I have no idea where else to ask this.

Do anyone like make a Game mode with me?

It will usually depend on what the game you want to make is, and how much work is done, and what you are willing to do. A great place to actively discuss these things is IRC.

Lua syntax question.
I want to register a new type of door in a mod. So, I figured I'd just need to make my mod depend on doors and then call doors:register_door
But when I do I get:

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

09:43:49: ERROR[main]: /usr/share/minetest/builtin/game/register.lua:60: Name doors:door_secret does not follow naming conventions: "modname:" or ":" prefix required

Which means I'm doing something STUPID. Any help here?

[Kilarin]

Never mind, it's always immediately obvious right after you post the question. wasn't complaining about calling doors:register_door, it was complaining about me naming the door doors:door_secret. duh!

If you want to add a node to a diffrent mod, you need to use:
minetest.register_node(":testmod:testnode",def)


EDIT: Whoops. Saw your 2nd post too late.

[Kilarin]

If you want to add a node to a diffrent mod, you need to use:
minetest.register_node(":testmod:testnode",def)

Useful info anyway!

Ok, next question, hopefully not so stupid.

I'm playing with making secret doors that look like background material. I'm sure someone has already done it, but the only mod I could find made panels you could walk through instead of actual doors that look like stone or wood etc.

As proof of concept, I can make a wooden door that looks like default_wood, or a cobble door that looks like default_cobble. Works.

BUT, what I'd like to do is enable a recipe in the form of:
group:wood,group:wood,
group:wood,group:wood,
group:wood,group:wood,special_item

where the item would use the default texture for whatever kind of wood you used in the recipe. Is that even possible?

If not, then how could I loop through whatever group:wood or group:stone (or any other groups) are available for a particular world, and build a recipe (and corresponding node) for each using the correct texture for the item?

[kaeza]

Something like this should do:

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

for name, def in pairs(minetest.registered_nodes) do
  if def.groups and ((def.groups.stone or 0) > 0) and def.tiles and def.tiles[1] then
    local basename = name:match("[^:]+:(.*)") -- Base name of item without `modname:' prefix.
    register_my_door(basename, def.tiles[1])
  end
end


[Kilarin]

That looks perfect kaeza, thanks!

I have the android version, will mods work for me

[Kilarin]

So, I've got a two sample "secret doors", one plain wood and one cobble. defined like 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

doors:register_door("secretdoor:door_secret_wood", {
   description = "Secret Door Wood",
   inventory_image = "door_wood.png",
   groups = {snappy=1,choppy=2,oddly_breakable_by_hand=2,flammable=2,door=1},
   tiles_bottom = {"default_wood.png", "default_wood.png"},
   tiles_top = {"default_wood.png", "default_wood.png"},
})


My problem is shading/lighting:



As you can see, the doors appear slightly darker than their surroundings. Is this because Doors:register_door sets drawtype = "nodebox" ???

[Casimir]

Yes this is because of the drawtype. Smooth lighting is not working for nodeboxes.

[Kilarin]

Yes this is because of the drawtype. Smooth lighting is not working for nodeboxes.

So, I am assuming then that there is NOT a solution right now? Changing the drawtype would not let it be thin as a door. Correct?

I mean, I can live with this, but it's not quite what I had been trying for. :)

[spootonium]

The Project: Attempting to implement a "co-operative hardcore mode", in which the death of all players triggers the deletion and re-generation of the map.
The Problem: In order to delete the map files (without causing errors and additional problems) the server will need to cease reading and writing actions and "close" those files, preferably without needing to shut down itself.
The Question: Is there a way, within the Lua API, to force-close the map, without shutting down the server?

EDIT - Bonus Question: Alternatively, is there a simple way to purge the map data?

[Casimir]

I don't know about deleting, but there are some alternatives:
* Random respawn anywhere on the map. When you respawn 30000 nodes away from your first spawn, you probably won't find your old world again.
* ABM to replace air with some other node, containing an check if the player died. That way the player would be stuck where he respawns.
* Use a protector mod to protect the whole world. You can still look at what you have build and save it with worldedit, but the game is over. I like this way the best. Together with some details it would also feel very smooth. Like, respawn exactly where you died, changing the skin to ghost (like BlockMens creature mod), grant fly and fast, and so on.

Hmm. None of those options really satisfy the purpose of what I want to accomplish. If actually deleting the map isn't possible without killing the server altogether, I suspect the best thing to do would be to purge map.db, and force a new mapgen with a new seed. Sadly, I don't know nearly enough about MySQL to do that safely.

[DeepGaze]

is there a tutorial on map gen- wanting to populate a world with a single node (air above the nodes though)

[Casimir]

Only one node and everything flat? Than this might be what you want: https://github.com/CasimirKaPazi/untern ... r/init.lua

[DeepGaze]

Thank you Casmir one more question: How can you fix the sky to night but keep the map lit, I have seen it on a server but can't remember witch?

[pandaro]

someone here has already used minetest.find_path ()?
are not able to make it work.
I post something, tell me if I'm wrong thanks!

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

ant.find_food=function(pos)
   local food=minetest.find_node_near(pos, 10, "default:apple")
   if food==nil then
      print(tostring("no"))
      
   else
      print(tostring("yes"))
      if dist>1 then
         local path=minetest.find_path(pos,food,2,1,1,"A*_noprefetch")
         print(tostring("path ")..dump(path))
      else
         minetest.remove_node(food)
      end
   end
   return food
end

Can someone post a link to the inventory_plus mod?

[kaeza]

Can someone post a link to the inventory_plus mod?

Have you tried using a web search engine?

[drkwv]

You do not need an own group for that:

1. is diggable by bare hands
oddly_breakable_by_hand = 3

2. but sounds like a stone upon digging (like a stone that is being digged by axe)
has nothing to do with tool, just use the stone sound:
sounds = default.node_sound_stone_defaults()

3. and has some custom crack pattern (if that possible)
change the crack_anylength.png texture to your custom crack pattern.

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_node("YourModName:YourBlockName", {
   tiles = {"YourTexture.png"},
   groups = {oddly_breakable_by_hand = 3}, -- or: groups = {oddly_breakable_by_hand = 3, choppy = 3},
   sounds = default.node_sound_stone_defaults(),
})


Please post your future modding questions here:
viewtopic.php?f=9&t=4668&p=146064#p146064

Thank you for the answer.
1. I set groups = {oddly_breakable_by_hand = 3} for node and now it's breaking with more situable sound, but I must admit that digging sound is not still the same as for groups = { cracky = 1, stone = 1 }. Any other thing I could do to fix the sound?
2. I changed crack_anylength.png, put it in my mods/mod/textures folder and cracking texture has changed for all blocks, not only from my mod. Is there a way to define custom cracking pattern only for a particular node?
