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

special_tiles = {
        {
            image="anyimage.png",
            backface_culling=false,
            animation={type="vertical_frames", aspect_w=16, aspect_h=16, length=0.8}
        },
        {
            image="anyimage.png",
            backface_culling=true,
            animation={type="vertical_frames", aspect_w=16, aspect_h=16, length=0.8}
        },
    },

[/spoiler] is this right

[DeepGaze]

my previous post was right.
new question: how do you set a "player controlled value"?

[Novacain]

So, I know it's possible, cause I've seen it done before, how can I have a .lua file load if another mod is installed? I want to add stairsplus support to one of my mods.

[DeepGaze]

animation={type="vertical_frames", aspect_w=638, aspect_h=638, length=?
is the last one for fps or what?

Question: How do I use the Sproxel *.sxl files as nodes? Which codes are in the node definition needed?

[Krock]

PING?

[LionsDen]

I don't know anything about entities. You might want to look up information about them or look at some of the mob mods.

you cannot use the *.sxl file directly.

you have to use this export script. With that you get a snippet of lua code describing a nodeboxe for each single voxel. You will have to built your init.lua around that.

You may also want to study this thread with some examples.

Thanks, I solved my problem :)

how do you:
#make a teleporting node?
#number controlled by chat command?
#a file with block coordinates?
#a secondary lua file?
#detect node type?
#act on the outcome?
#and use the force load feature?

[DeepGaze]

#how to make a node when stepped on teleports you to the other node
#:(
# what?
#thank you
#define if the node is an air or water or other
#:(

sorry for the confusion. the only reason I am hounding this topic is:, the tutorial for modding is great but lacks depth and only shows how to make a simple wood node. not trying to be offensive

[Casimir]

So minetest.forceload_block(pos) does not generate the mapbock?

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

somefunction(pos)
    print ("[loadmap] loading position ("..pos.x.." "..pos.y.." "..pos.z..")")
    minetest.forceload_block(pos)
end

minetest.register_on_generated(function(minp, maxp, seed)
    print ("[loadmap] chunk minp ("..minp.x.." "..minp.y.." "..minp.z..")")
end)


Only the first message gets printed.

(Ups, was in wrong thread.)

For your first question you could look at this mod which has nodes that teleport you by you clicking on them. (https://github.com/rocketslime11/waveroad)

[DeepGaze]

thank you for the resource, but i fear it has swept over my head like a proverbial albatross. I am going to return to the project idea at a later date, but if anyone wants it:
you step onto this node and it moves the player forward until the player hits an air-like node

Topic: Do not fully understand how to use a built-in method/function

Reason: From the name, it seems to be the method/function I require for what I am trying to do in a mod I am working on.

More Info: The method/function is "minetest.register_on_craft". However I cannot find any good information on how it is used. What I am trying to accomplish using this method/function is allow a crafting item to be used multiple times, but also have a chance of it "breaking".

Also I'm the type of person that requires an example to learn, I need to see it being used to fully understand it.

Please note that this isn't a finished product, and is still a work-in-progress and I have not tested the code.

But like I said, I couldn't find any good information on it's usage. PilzAdam gave me a small example of it being used, however it didn't use the main variable I'm looking to use, which is the "old_craft_grid".

How I currently have the code written is below in the spoiler.

[spoiler]

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_on_craft(function(itemstack, player, old_craft_grid, craft_inv)
    local seed = os.time()
    local recipe = minetest.get_craft_recipe(item)
    local inv = minetest.get_inventory({type="player", name=player})
    local rh = true
    if old_craft_grid = recipe('PoweredMachines:Copper_Plate') then
        math.randomseed( seed ),
        if math.random( 1, 100) < 15 then
            itemstack = 'PoweredMachines:BrokenHammer',
            inv:add_item("main", ItemStack('PoweredMachines:Copper_Plate'),
            rh = false
            return itemstack,
        end
        if rh then
            inv:add_item("main", ItemStack('PoweredMachines:Hammer'),
        end
    elseif old_craft_grid = recipe('PoweredMachines:Steal_Plate') then
        math.randomseed( seed ),
            if math.random( 1, 100) < 15 then
                itemstack = 'PoweredMachines:BrokenHammer',
                inv:add_item("main", ItemStack('PoweredMachines:Steal_Plate'),
                rh = false
                return itemstack,
            end
        if rh then
            inv:add_item("main", ItemStack('PoweredMachines:Hammer'),
        end
    end
end
end)

You can't do "if old_craft_grid = ", it will never work. What you need to do is to test each of the items in the craft grid to check it has the correct name. See an example about how to use it here: https://gist.github.com/Novatux/7179966

[Krock]

Somehow I get doubled nodes, but I try to modify the clone of the 1st node:

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("extranodes:unlocked_sign", minetest.registered_nodes["default:sign_wall"])
minetest.registered_nodes["extranodes:unlocked_sign"].description = "Unlocked sign"
minetest.registered_nodes["extranodes:unlocked_sign"].drop = "extranodes:unlocked_sign"

minetest.register_craft({
    output = 'extranodes:unlocked_sign 4',
    recipe = {
        {'default:wood','default:wood','default:wood'},
        {'default:wood','default:wood','default:stick'},
        {'','default:stick',''}
    }
})
...

Ah, okays. Thanks :D that helps a lot.

(sorry for re-asking)
a value controlled by a chat command?

[LandMine]

Is there an easy way to do the following......a mod that would allow a list to be displayed with the name of the players and the time they have been ALIVE? ............... for example a player spawns and the timer begins, then after lets say 10 min player dies, the timer goes back to 0:00 but the rest of the players timers remain normal, and the time SHOULD NOT reset when a player logs out that is if "BOB" has been 0:30 min alive and logs out, and comes back in his timer remains at 0:30 and continues.....

Also a kill counter, for example "BOB" kills "JOE" so on the list bob has a Kill: 1, which will continue to increase if bob kills more players and will go back to 0 if someone kills bob

So just to have an idea it would something like this:

NAME TIME ALIVE KILLS
Bob 01:30 5
James 00:23 1
Joe 00:02 0
Etc 00:01 0

So it would be from highest to lowest depending on ALIVE TIME. Please advice me on a way thanks in advanced

The stats mod may either do that already or be adjustable.

Finding out who/what killed a player is currently impossible to my knowledge. That would be great to have for logging (=to know which players to get rid off) and for better messages.

thank you sokomine i will look at the code and see what can be done, and i dont want to know who killed who, just how many people they have killed which would be great, thanks sokomine

*BUMP for https://forum.minetest.net/viewtopic.php?pid=130675#p130675*

[cypher-neo]

Quick question.
I made a modpack a while ago, but it no longer works with the current game. After doing some investigation on the problem, I realized that modpacks need to have a modpack.txt in the folder somewhere (based on https://forum.minetest.net/viewtopic.php?id=6450 )
I've tried downloading some modpacks to get examples of what info needs to go in modpack.txt, but none of the modpacks I download have this (and no modpacks I've downloaded work!)

Can someone explain to me make a modpack, how to create a modpack.txt, and give an example of the content that needs to go in that file?

Edit: Forgot to include my specs.
Using Minetest 0.4.9

[Krock]

@post abrove:
step by step:
create folder "[modpack_name_goes_here]" in the mods folder
open the folder
create an empty "modpack.txt" file
:loopstart
create folder "[mod_name_goes_here]" into your modpack folder
open the folder
make a mod into that folder
leave the folder
goto loopstart

[hoodedice]

I'm expressing this as a general programming problem, but it is very related to minetest modding. I'm writing the program in some sort of pseudocode:

function:on_call(dtime)
local timer = 0
minetest.register_globalstep(function(dtime)
timer = dtime+timer
if timer < 0.10 then
run code
timer = 0
end
end
---------------------------------------------------------------------------

What happens is - Since the dtime function is nested within another dtime, it gets called every dtime. I need a part of the 'run code' to stop running after timer > 0.10
I cannot move the 'run code' anywhere else. It needs to stay within that on_call function

How about 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

local ttime = 0
local called_ttime = false
function:on_call(ntime)
      called_ttime = true
      ttime = ntime
end

minetest.register_globalstep(function(dtime)
      ttime = dtime+ttime
      if(ttime > 0.10) then --every 0.1 second, IF SERVER IS ENOUGH FAST
            ttime = 0
            if(called_ttime) then
                  called_ttime = false
                  run code
            end
      end
end
