How can I make a tool item wear when used pointing at nothing?

I tried this but is does not seem to have any effect.

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_use = function(itemstack, user, pointed_thing)
        itemstack:add_wear(100)
        user:set_wielded_item(itemstack)
    end,

on_use is only called when pointing at something.

on_use is only called when pointing at something.

That is not true. I can prove this by adding a print statement in there, point at the sky and press LMB

I think the problem is with how I am commiting the itemstack, though I got that idea from the dev wiki http://dev.minetest.net/Player

(changes will need to be "committed" by calling object:set_wielded_item(modifiedStack)

[PilzAdam]

Oh, it was on_place() that was only called when pointing at something, sorry, my bad.

You should try return itemstack instead of set_wielded_item().

No problem, returning the itemstack does the business.

Thank you once again.

I've the feeling, it has already posted here alot but:
How do I make a crafting grid, that needs a pickaxe, which only gets a little damaged, when using it for crafting?

(just giving back is good too)

Okay, I've already found:

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

replacements = { ... with ... }

Is there also a way to damage it?

*ahem* Just follow this simple steps:
> Open your browser
> Go to https://github.com/minetest/minetest/blob/master/doc/lua_api.txt
> Press [Ctrl] + F ( default for Firefox if im not mistaken )
> Input 'wear' within the search field
> Iterate through document until functions are found

Thats how you get this result: https://github.com/minetest/minetest/blob/master/doc/lua_api.txt#L1754

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:

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

[Casimir]

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

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/blob/master/doc/lua_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]

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...
