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:

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?

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.

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:

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:

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. :)

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

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?

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!

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?

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.

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?

Do minetest.get_node_light(pos) working? I'm getting 0 all the time.

[BlockMen]

Do minetest.get_node_light(pos) working? I'm getting 0 all the time.

Yes, it works. I guess you are using a wrong pos. Imagine that the function returns the light value "inside" of the node at given position. So if you want to get the light value ontop your node you need to get the light value above.
Example:


If you want get the light value ontop of this dirt block you need to add

Code: Select all

pos.y = pos.y+1

to your code to get the correct value

[pandaro]

Someone here can, at least, ensure me that minetest.find_path() work properly?
I begin to suspect a bug. In which case I will report it on github.
But if someone tells me, at least, that he work, then I'm wrong!
thanks

there is a command for suicide? Can you show me?
