Someone could show me a tutorial for creating mods

Read the code for other (simple) mods, and learn how they do stuff. That's the best way to learn.

Does anyone know how to set up schematics?

Sorry about this just bumping the question in case someone that does know didn't see it.

Title:How do I upload a Model?

You see I made a model and I like to, inport it on, Minetest but how do I?

And is there a way have the textures to work to like the player.

What did you make the model on? Blender? I think you have to import it to a .X file using DirectX or something.

where can I download DirectX or Blender?

Download blender from it's website- just search Blender 3d modelling.

It has a built-in DirectX exporter to export the models.

Does anyone know how to set up schematics?

Sorry about this just bumping the question in case someone that does know didn't see it.

Question would be what exactly you want to know. Docs says this:

Schematics:
minetest.create_schematic(p1, p2, probability_list, filename)
^ Create a schematic from the volume of map specified by the box formed by p1 and p2.
^ Apply the specified probability values to the specified nodes in probability_list.
^ probability_list is an array of tables containing two fields, pos and prob.
^ pos is the 3d vector specifying the absolute coordinates of the node being modified,
^ and prob is the integer value from 0 to 255 of the probability (see: Schematic specifier).
^ If there are two or more entries with the same pos value, the last occuring in the array is used.
^ If pos is not inside the box formed by p1 and p2, it is ignored.
^ If probability_list is nil, no probabilities are applied.
^ Saves schematic in the Minetest Schematic format to filename.

That would lead ( to me ) to a example call like this:

minetest.create_schematic( {x=1,y=1,z=0}, {x=10,y=10,z=5}, nil, 'test_schematic' )

Which would lead to a box with a x_length = 10 , y_length = 10, height = 6, didn't test it though. Was how i understood the explanation. Otherwise did you took a look at the City generator of MKitsune? Its using schematics iirc.

I will look into what you showed me but MirceaKitsune's files are all in .mts and I can't open those or edit them so they just look like mush.

[Sokomine]

I will look into what you showed me but MirceaKitsune's files are all in .mts and I can't open those or edit them so they just look like mush.

Those .mts files are in a binary format and not intended to be edited with a normal editor.

The best way to create your own schematics is to use Worldedit:

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

//mtschemcreate your_file_name


ought to do it.

Thanks for the help Sokomine a sneak peek of things to come:

Hi, im just wondering, for my mod i'd like to make a alchemy furnace like thing. It would be like the alloy furnaces from things like technic, however i do not know how to add in the second slot for things to smelt like what the alloy furnaces have. Would someone be able to help? and also how would you make a new crafting type like what the furnace has (cooking) as i would like to make alchemy as a type. thanks for any help

About the best thing I can tell you is to examine the code for technic, both for the alloy furnace and the alloy furnace recipes.

i have but have had no luck, ive also looked at this https://forum.minetest.net/viewtopic.php?id=3546 with only little success plus i dont like editing other peoples code and posting it because it doesnt look like i made the mod, i only look at other code to see if im doing stuff right

[wcwyes]

If you want to use your own code take their code and use your own words to describe it like writing a book, besides we're all in this together.

[LionsDen]

And you will be learning how other people do it and possibly improving your own code in the process. Plus sometimes you will find errors in their code that you can tell them about. I have done that once or twice with some stuff in minetest. :)

[durtective6]

Also if i have a dependency which is someone elses mod, am i allowed to include it as a component of a mod pack
also does wtfpl cover code like code editing?

[LionsDen]

If it says the code is WTFPL then it means that anyone can do anything that they want to the code and the author doesn't care. You don't even have to credit them but it is always nice anyway to do so. Textures and sounds may or may not be WTFPL but usually the mod will tell you whatever license they have. Basically WTFPL means public domain.

[leetelate]

exactily - all my stuff is wtfpl and you can use it however you want, but some other modders use different licenses that require notification that you are using it - just read the readme on their mod to know what to do

oh and if you use a texture from somewhere (like the web), be sure you trace it yourself and not just drop it in as there are 'programmed pixels' that report use back to the owner - weird but true - just trace it out yourself (edge-detect,fill, tweak) and don't just drop it in

worlds made from a mod have to have the default and any dependencies included with them in the game, and that requires the license for those mods be included - i just put in a disclaimer saying it is in there because it has to be in there since it is a world and reference the default's readme (slacking, yes)

Once i get my mits on 0.4.8 stable how do i make "air" nodes drownable, for my space mods, is it even possible?

I found the spawn command on our server

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

-- Suicide command

minetest.register_chatcommand("spawn",
{
    params = "",
    description = "Causes you to die and respawn",
    func = function(name, param)
        minetest.env:get_player_by_name(name):set_hp(0);
    end
})



how would I get the static spawn instead of set_hp(0)?

[fairiestoy]

I suggest you dig through this here:
Multispawn
Use this mod as it is, or just extract the spawn/teleport part of it

[wcwyes]

None of these appear to refer to the static spawn.

The answer it seems is yes, "air" can be redefined in lua and made drownable.
"air" is a node defined in 'builtin/misc_register.lua' https://github.com/minetest/minetest/blob/master/builtin/misc_register.lua#L276

And again i suggest to use google. If you google 'minetest static spawn', you get enough answers ( i prefer the second link, is more up to date ). Question is: Are you talking about the spawn set in config: Use minetest.setting_get ( or so ) from the API to get the value and let the user spawn there. Otherwise use the mod i linked as reference to set your own spawn point.

It says setpos expects a table. not a string

There has got to be a faster way to substitute one node for another on a massive scale during mapgen..

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

locations = minetest.find_nodes_in_area(minp, maxp, sand_nodes)
for k,v in ipairs(locations) do
minetest.set_node( v, {name=sand_replacement_node} )
end

This slows mapgen waaaay down. is there a better way to do this?
