How do you read the state of a checkbox?

I've configured a formspec with fields, labels, dropdowns, and a checkbox. All of them display as expected when I right-click on the node. Within on_receive_fields, I can access the fields and dropdowns via fields.[field or dropdown name], but I can't access the checkbox in the same way. When I add

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 k,v in pairs(fields) do
   print(k)
end

to my on_receive_fields code, the log shows a list which includes all the fields and dropdowns, but doesn't include the checkbox. Where is the state of the checkbox stored?

Hello

When i place a nodebox wich has facedir as parameter all the textures of the node are turning in the same time.
Is there a parameter / function wiche exists to keep some textures aligned to "the north of the map" in my case for top and bottom texture, to keep them aligned, at this time it's breaking the visual style of the texture.

If you already didn't, rename the folder name of your mods to the name that in their topics is written between the brackets [ ]

Example: mobs-master --> mobs

Is it possible to, in one mod, override a function in a different mod?

For example, the Carts mod contains: function cart:on_step(dtime)
Could I create a mod in a DIFFERENT folder, cartsplus for example, set the depends to carts, then override the on_step function so carts uses my new on_place function instead of it's original?

I tried just defining
cart:function on_step(dtime)
in cartsplus, but it ran the old carts on_step function not my replacement.

I tried
cart.on_step=cartplus_on_step

and that didn't work. I tried:

minetest.override_item(cart, {on_step = cartplus_on_step,})

and got:

20:42:59: ERROR[main]: ========== ERROR FROM LUA ===========
20:42:59: ERROR[main]: Failed to load and run script from

20:42:59: ERROR[main]: ======= END OF ERROR FROM LUA ========

IS there a way to do this?
I was hoping not to just fork carts, because that means you've got two different mods with the same folder name, and I foresee difficulties with that. And I don't want to redefine everything because then you would have both carts and cartsplus each defining a different kind of cart with different behavior, which could get confusing.

Any help would be greatly appreciated.

[HeroOfTheWinds]

I was trying to do something like this in lockpicks. All I can think of is that override_item SHOULD work, and you're merely using it wrong. I would copy the whole function instead of a reference to the function, but that's just me. Disregard that if you're redefining multiple objects using that function. Also, judging by the error, you should put the actual name of the cart as a string, e.g. "carts:cart" or whatever it is you are overriding. I think that's your problem there.

Thanks heaps working now

My thoughts exactly.

you should put the actual name of the cart as a string, e.g. "carts:cart" or whatever it is you are overriding. I think that's your problem there.

That makes sense! BUT, while it eliminated the error, the newly redefined on_step function is still not running. <sigh>

I want to know that too...

[HeroOfTheWinds]

Does anybody know what parameters I would have to use for perlin noise in Lua to simulate the humidity and temperature features that were in mgv7 for a while? I know about the minetest.config trick when using mgv7, but I need this for singlenode.

[LionsDen]

I think paramat and his mods might be one of the best places for temperature and humidity perlin noise.

[spootonium]

Perhaps a bit of a broad question, but:
What are the capabilities of game.conf, beyond name and common_mods? Can it, for example, overload any of the settings in minetest.conf?

The reason I ask is, that I'm looking for an elegant way to be able to impose certain settings for a game, that wouldn't be relevent or optimal for other games. I'm aware of minetest.setting_set(), but I'm hoping for a method slightly less blunt than altering configs for the whole programme for one particular use-case.

It's rather funny that I was just asking this yesterday on IRC. game.conf can not override minetest.config. However, you can include a separate minetest.config in the game's own folder, which will then take precedence over the main minetest.config, as far as I know.

Sounds legit. Odd that it's not documented, though. Thanks.

[spootonium]

Further to my previous question, are there any other fields that that game.conf has, other than name or common_mods? For that matter, is there any reason why it could/should not be utilised by modders as a game-wide settings file (i.e. with custom fields)? (It occurs to me that I may have stepped beyond the scope of this forum, but if I can get a complete, authoritive answer, I intend to put it in the wiki.)

And what about modpack.txt? I know that it needn't necessary be empty, but would it "break" anything if it were actually read/written. I'm thinking about things like version strings, manifest, hash/checksum - possibly through to modpack-wide defaults, and those sorts of odd-&-ends that are useful to have in one place, but which don't really belong in a README or .conf(ig).

Anyone want to have a go at answering that? :-D

You can place a minetest.conf file in the same directory as game.conf, and it overrides default settings.

modpack.txt contents are never read by the game.

That clarified my previous question, but what other fields does/can game.conf contain?

modpack.txt contents are never read by the game.

Presumably, therefore, it can contain any text that I want, and be read and/or written while the game is running.

Cheers.

Does anybody know what parameters I would have to use for perlin noise in Lua to simulate the humidity and temperature features that were in mgv7 for a while?

Temp and humidity noises are and will always be in mgv7, the default noise params used in your version of mgv7 are shown in minetest.conf.example, and are currently:

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

# Offset, scale, spread factor, seed offset, number of octaves, persistence
#mgv7_np_heat = 25, 50, (500, 500, 500), 35293, 1, 0
#mgv7_np_humidity = 50, 31.25, (750, 750, 750), 12094, 2, 0.6

The noise values output are determined by offset and scale, and will be -25 to 75 for temp, 0 to 100 for humidity, i use 0 and 1 for offset and scale in my mods to get a noise value varying roughly between -1 and 1.

Has anyone yet made a Alt. Minetest?
Like have different crafting ways and, maybe a texture style like my Avatar looks like?
Yeah that the chest will look like if no one did so I will start working on it even more.

Go to the mods/snow/ folder, create a file named "depends.txt" (if there's not already one) and add "default" (without quotes) to it.

I would like to create a "pay door". Basically, it can only be opened if a player inserts a specified item into it (eg - they would right-click on the door, and an inventory would open. The player would add 10 cobble stone blocks to this inventory (for example), and then the door would open).

Any ideas on how I could do this?

Have a function that opens the door, then have the actual door node have a callback for on_metadata_inventory_put that checks the ItemStack being placed in the door's inventory to see if it matches the door's payment criteria, and if so, calls the door opening function.

We can't really write a mod for you. Look on http://dev.minetest.net/Main_Page for modding stuff. Also, default code is your friend. In your case, I would look at the chest code in minetest_game, and the door code. I would also look at formspecs on the minetest dev wiki.

[Pavel_S]

I have a trouble. I use "local item = clicker:get_wielded_item()" in on_rightclick entity callback and then "item:take_item()", but it don`t work. the item is on it`t place. What I do wrong?
clicker:get_wielded_item():take_item() - also don`t work.

Of course not. I'm just a bit stumped. I am semi-familiar with how to create inventories for items (such as chests), and I'm quite familiar with the code for doors. Based on that, I could make a door that also functions as a chest lol. But I just can't seem to figure out how to make the door look for a specific item in its inventory, and only open when said item is present.

I keep taking a look at the wiki though!

I think some already did something like that. It's a lock and key door.
