How do I form a tree that contains my wood block and my leaf block?

How do I form a tree that contains my wood block and my leaf block?

Search for tree in your minetest/doc/lua_api.txt fot the use of L-system trees.

Thank you, I was told this before by kaeza but he didn't really what to put in the tree definition before but I searched more and found it so thanks again, well I never asked him further more about it lol anyway ye thanks

Can I put dibs on a mod idea?
I'm working on this great project and it would go to waste if someone finishes theirs that turns out to be the same concept as mine :/

[paramat]

No you can't :) make it anyway and if in the unlikely event someone else makes something similar just make yours better.

What's a good way to generate cocoa in jungle trees? I've thought of generating them using the ore structure I'm not to sure that's the best option to choose. I need the cocoa to generate even if the tree was grown through sapling.

Also, what would be the best method for generating pumpkins at well?

I'm not sure about the tree, but you can look at the grass spawning code for use in the pumpkins: https://github.com/minetest/minetest_game/blob/master/mods/default/mapgen.lua

For some reason the plant for one of the new biomes won't grow and I can't figure out why. Could anyone more experienced tell me?

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

local function place_seed(itemstack, placer, pointed_thing, plantname)
    local pt = pointed_thing
    -- check if pointing at a node
    if not pt then
        return

    -- return if any of the nodes is not registered
    if not minetest.registered_nodes[under.name] then
        return
    end
    if not minetest.registered_nodes[above.name] then
        return
    end

For some reason the plant for one of the new biomes won't grow and I can't figure out why.

chance = 10000,

Did you try it with a chance = 1 or 2?

Oops I forgot chances were inverted thank you.

How about a person protection block that when placed creates a 5x5 area around it where you cannot be hit, attacked or hurt (ideal for spawn areas until your game loads, or homes)... Of course make them hard to craft, maybe 8 diamond blocks and a mithril block in the centre, otherwise people's whole house will be filled with them...

[Casimir]

Can you somehow get pointed_thing for a given player? I don't mean "function(pointed_thing)", more like "pointed_thing = player.get_pointed_thing".

[Enke]

I realise this sounds derpy, but here goes.

I am trying to make my first mod. It is very simple, only adds two blocks. This is my code:

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("troll:troll", {
    tiles = {"troll:troll.png"},
    groups = {snappy=1,choppy=2,oddly_breakable_by_hand=2,flammable=3},
})
minetest.register_node("troll:derp", {
    tiles = {"troll:derp.png"},
    groups = {snappy=1,choppy=3,oddly_breakable_by_han=2,flmmable=1},
})

When I try to test it in my world, I get the following error:

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

22:03:08: ERROR[main]: generateImage(): Could not load image "troll:troll.png" while building texture
22:03:08: ERROR[main]: generateImage(): Creating a dummy image for "troll:troll.png"
22:03:08: ERROR[main]: generateImage(): Could not load image "troll:derp.png" while building texture
22:03:08: ERROR[main]: generateImage(): Creating a dummy image for "troll:derp.png"

I have the mod enabled and textures created for both blocks, and have them named "troll_troll" and "troll_derp". Could someone help me with this?

(P.S., this mod will not be released, just a little test to see if I can even make mods.)

[paramat]

tiles should be "troll_troll.png" not "troll:troll.png" etc :)

[Enke]

*WHAP* I don't know how I missed that. Thank you.

[Enke]

does this:

chance = 10,

make it so that there is a 10% chance or a 90% chance?

*Edit* Okay, working on a real mod. I am trying to register craftitems, and here is my code:

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_craftitem("inlaid:inlaytool", {
    description = "Inlay tool",
    inventory_image = "inlaid_inlaytool.png",
})

minetest.register_craftitem("inlaid:chisel", {
    description = "Chisel",
    inventory_image = "inlaid_chisel.png",
})

and I get this error when I run it:

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

21:52:48: ERROR[main]: ...minetest-0.4.7-5094a39-win32\bin\..\mods\inlaid\init.lua:15: unfinished string near '"inlaid_chisel.png,'

Can someone explain?

[LionsDen]

It's the last comma in each item's definition. A comma is only there when there is more information to be placed in the definition. Try removing them and try again.

[paramat]

No those last commas are fine and should not cause a problem. Can't see anything wrong in the code, might be an error outside the code you have pasted here.

are you sure you posted the relevant part of your code? check line numbers again. The string quoted in the error message is indeed unfinished, and should be closed with and " before the comma.

[Enke]

This is all the code I have, and I have no clue why the error message says that the line is unfinished.

[LionsDen]

Did you do a direct copy/paste of your code here? Because according to your error you are missing a quote mark " at the end of the line that has inlaid_chisel.png. Maybe while typing it in for the lua file your finger accidentally pressed 2 keys at once which causes some keyboards to send some other key code to the computer. It's very easy to do. I have found that sometimes the only way to fix that type of error is select the line around where the problem is and delete it and then retype it in.

[jin_xi]

lol, sry to have bothered you

[Enke]

Wow, major derp.... the code I was fiddling with was my backup copy. It did need quote marks in the original code. Thanks guys.

Geez, a derp every day... I'm terribly sorry to have troubled you.

Where is the code for the default inventory stored?

[Neon]

I have an atmospheric node that seems to block the growth of trees. What would I need to set so trees will replace the node at the appropriate locations, rather than not grow at those locations?

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("luna:oxygen", {
        drawtype = "glasslike",
        tiles = {"atmos.png"},
        paramtype = "light",
        sunlight_propagates = true,
        walkable = false,
        pointable = false,
        diggable = false,
        buildable_to = true,
        post_effect_color = {a=24, r=255, g=255, b=255},
        groups = {not_in_creative_inventory=1, air_like=1}
})

Thank you HD, but I am already using air for something else.

[Dan Duncombe]

Why not give it draw type air like?
