How i can make throwing (like throwing mod) from block, then i punch block and block throw something.??:_?:?

Do you expect someone to write the mod for you? Get started and post any questions you have.

I've another problem, when use "allow_metadata_inventory_put" and "allow_metadata_inventory_take", then I can't get the new stack-informations, it will always show up the previous stack.
How can I solve this? I've found the circular saw codes, which do parts of what I try to do, but those code aren't easy to understand

EDIT: solved myself...

how must i set up the particle spawner to add particles like this:

Code: Select all

minetest.add_particlespawner(amount, time,
    minpos, maxpos,
    minvel, maxvel,
    minacc, maxacc,
    minexptime, maxexptime,
    minsize, maxsize,
    collisiondetection, texture, playername)

Can someone make a tutorial on how to use particles/the particle spawner? The api txt is just confusing me.

I personally dont think its confusing... could you tell me your problems with it, so it would be easier to write the tutorial?

Just define your own get_craft_result() and register_craft() functions.

thanks that helped me a lot

Can someone tell the correct furnace definition and what I can customize within the code. Also please don't link the development wiki because it honestly doesn't assist in any way especially with functions.

How do I check for hostile mobs around me?

Can anyone help me?

the name of it is: default:furnace
All nodes/blocks/cubes acn you find in the folder games\Minetest_game\mods\default\ (nodes.lua?)

How does this help at all! I am attempting to create my own furnace but I want to know how the functions and formspec coincide with each other and what I can tailor to create my very own furnace.

Get all entities in the area, compare the table with a table of all known hostile mobs (for ... do ...).

I read it again, and now I understand. No problem.



Recently there where some commits about ground contend. In the lua_api.txt it says "is_ground_content = false, -- Currently not used for anything", so why the changes? Do modders have to care about that?

I created a mod. I used the following materials: "https://github.com/minetest/minetest/bl ... ua_api.txt".I used the "C + +"
My problem is that I do not know which license should I describe in my mod.
Someone tell me what I should by? do not quite understand it yet.

on this page you can choose (create) ur own license http://creativecommons.org/choose/

[Sokomine]

My problem is that I do not know which license should I describe in my mod.

Do you have any special wishes regarding your license? If you want your mod to be moved to mod releases, it has to be an open license that allows much. I personally prefer the GPLv3, but there can be almost "wars" over which license is best. Some people also love to use WTFPL.

The CC licenses IMHO are less well suited for code. They aim at other creative work like images, texts, animations etc.

[webdesigner97]

How can I make sure that a certain piece of code gets executed when ALL nodes of ALL mods are registered?

[BrunoMine]

I really do not understand how will the license. I created the mod and just want everyone to use it. I post the forum "Modding Geral"?

Okay. If you want everyone to be able to use, edit and distribute the mod, then use GPLv3. If you want any other license, you might try LGPL or some other one. CC licenses aren't really for code...

Yes!
Get to work!

Ok, so I'm putting together a mod for personal use, and I added a food item. But on use of this food item, I want part of it to return back to the inventory (it's soda, I want an empty bottle back). I have no coding experience, so I'm just going on what I see in minetest_game mods and other mods. I have this...

Code: Select all

minetest.register_craftitem("morestuff:apple_soda", {
    description = "Apple Soda",
    inventory_image = "apple_soda.png",
    on_use = minetest.item_eat(3),
    replacements = { {"morestuff:apple_soda", "vessels:glass_bottle"} },
})

Can someone tell me where I'm going wrong?

Code: Select all

... replacements = { { ...

those are used in the crafting grid
Codes from moretree mod:

Code: Select all

-- Food recipes!

minetest.register_craftitem("moretrees:coconut_milk", {
    description = "Coconut Milk",
    inventory_image = "moretrees_coconut_milk_inv.png",
    wield_image = "moretrees_coconut_milk.png",
    on_use = minetest.item_eat(2),
})

More I can't help you, try and try, maybe you'll find a possible soulation

EDIT:
you could do it like the bucket mod: (modifed)

Code: Select all

on_use = function(itemstack, user, pointed_thing)
        -- Dig if pointed on node
        if pointed_thing.type == "node" then
            return
        end
        minetest.item_eat(3)
        return ItemStack({name = "vessels:glass_bottle"})
    end,

This worked perfectly, thanks!
