how do you use the range for tools thing

Just put this into the tool definition. (replace 10 with whatever range you want)

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

range = 10,

Do you know the normal value for the range?

I don't know what it is exactly, but it is probably either 4 or 5.

EDIT: I asked on IRC, and it's 4.0

I've encountered a new error, if I put 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

for c=1,2,3,4,5,6,7,8 do

I get "do expected near ,"

If I put 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

for c=1,8 do

I get "attempt to concatenate global 'c' a nil value"
Any fixes?

First error you should look at the implementation of the for [..] do statement in the lua docs:

stat ::= for Name `=´ exp `,´ exp [`,´ exp] do block end

Therefore only three control expressions are allowed. Your error code tries to tell you, that after the third value he found a ',' where the interpreter expected a do to be since thats how the syntax should look like.

Your second code should work since i quick tried exactly
that in an interactive lua session. Are you sure to not made any use of c anywhere else? Try naming it different maybe.

[Chinchow]

Thanks for the assistance I was looking at lua today and realized the first error's problem
As for the second one I have used it in the group name : plants_wheat=..i

Is it possible to stop an abm after a certain amount of time?

[fairiestoy]

Afaik thats not possible.
I don't know what you want to code, even though you mentioned something about plants. Anyway, is it necessary in your code to use an ABM? If not, and you need a timer that can be turned off whenever needed, try NodeTimers.

None that I know of.

Is it possible to remove a node/item? For example, I'm making a food mod that has bananas, but PilzAdam's farming_plus mod has them too. The only thing I could do was to redefine his bananas:

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.register_node(":farming_plus:banana", {
    description = "banana",
    groups = {not_in_creative_inventory=1}
})

And after that, I tried minetest.register_alias, but all I got with "/giveme farming_plus:banana" in Minetest was an unknown node. In my code, I registered the alias after redefining Adam's bananas:

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.register_node(":farming_plus:banana", {
    description = "banana",
    groups = {not_in_creative_inventory=1}
})

minetest.register_alias("farming_plus:banana", "fruits:banana")

Redefining an item should not cause any problems with recipes, unless you use a different name for the item (in which case it would need support form all other mods that need bananas).

Do not register any alias for your item.

Also, it's better to "copy" the original node definition and modify it instead of creating it from scratch. See this thread for more info.

The homedecor mod also has some code that uses this approach to override fences to be able to attach signs to them.

Edit: typo.

Is it possible to have a node with a custom right-click gui. What I want is a user editable string with two buttons (save and cancel). Is there a mod with a working example of something similar?

Yes, you'll need formspec. This is how default signs are implemented. http://dev.minetest.net/formspec

[Gronx]

Exactly what I needed. Cheers :-)

any idea how to make /spawn not kill you?

any idea how to make /spawn not kill you?

Pfft, that's easy. Ever played on redcrab's server? /spawn just teleports you, no need for dying here.

[wcwyes]

didn't see it in public. Do you know if he has a downloadable copy or how to immatate it?, I haven't even been able to figure out where /spawn is referenced.

I don't think he does, but it shouldn't be too hard to make.

[wcwyes]

It would be easier if I knew where to find the register.chat_command for it, Any idea where I could find it

will anyone help me with the bedrock mod

[leetelate]

will anyone help me with the bedrock mod

um, what do you need help with?

[Element]

i have this bedrock mod and i cant build or destroy anything at or under the bedrock layer, there is a message that pops up saying, the area is protected

[leetelate]

is this running on a server? singleplayer, what? - standard tech support question: did it ever work? if so, what is the level at which it doesn't work now?

[Element]

its on a single player server and the layer is only -1000 nodes deep

[leetelate]

SOLVED in the mod post - simple hax would be to...unconfigure the mod, do your stuff, reconfigure the mod...you may have to wade throogh a bunch of 'unknown nodes', but it would (most probably) work.

[Element]

as my post in the forum, my tnt can still blow up the bedrock

where is the register chat command spawn?

[Topywo]

where is the register chat command spawn?

Under:
minetest/builtin/chatcommands.lua

(search for spawn)

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.register_chatcommand("spawnentity", {
    params = "<entityname>",
    description = "spawn entity at your position",
    privs = {give=true, interact=true},
    func = function(name, param)
        local entityname = string.match(param, "(.+)$")
        if not entityname then
            minetest.chat_send_player(name, "entityname required")
            return
        end
        print('/spawnentity invoked, entityname="'..entityname..'"')
        local player = minetest.get_player_by_name(name)
        if player == nil then
            print("Unable to spawn entity, player is nil")
            return true -- Handled chat message
        end
        local p = player:getpos()
        p.y = p.y + 1
        minetest.add_entity(p, entityname)
        minetest.chat_send_player(name, '"'..entityname
                ..'" spawned.');
    end,
})

Does anyone know how to set up schematics?

Spawn is afaik a self-written mod. if you just start a singleplayer world, /spawn shouldn't be available ( at least on my 0.4.7+ versions ). If you want some spawn commands, search the forum by using the search tool respectively.
Here is an example i know from BrandonReese: Custom Spawn points. It works different, but should give you a good feeling. And next time:
Hell use the search tool in the top bar(!)
