[MOD] Tool ranks [toolranks]

[KCoombes]

Is there a limit to how many levels a tool can gain?

[lisacvuk]

6, at 1600 nodes

[azekill_DIABLO]

cuz otherwise my pick would have somethin' like: lvl 78...

Love this. Definitely adds to gameplay : )

Code: Select all

wear = digparams.wear / (1 + level / 4)

I simply brute-forced the above code. No idea how it works, but it seems about right in-game.

For levels 1-6 that code multiplies wear by 1.0, 0.67, 0.57, 0.5, 0.44, and 0.4. The following code is more balanced and offers more than just 6 levels and 1600 broken nodes to get a max level tool.

Code: Select all

toolranks = {
  -- these two settings can be tweaked by the server admin
  min_bits = 6, -- 64 nodes to get level 1
-- min_bits = 7, -- 128 nodes to get level 1
  max_level = 15
}
toolranks.min_nodes = math.pow(2, toolranks.min_bits)
toolranks.max_level_nodes = math.pow(2, toolranks.max_level+toolranks.min_bits-1)

function toolranks.get_level(uses)
  if uses < toolranks.min_nodes then return 0 end
  if uses >= toolranks.max_level_nodes then return toolranks.max_level end
  return 1 + math.log(math.floor(uses / toolranks.min_nodes)) / math.log(2)
end

-- the level>1 check is not needed
local wear = digparams.wear * (1 - (level / toolranks.max_level))

With 15 levels you get wear multipliers of 1.0, 0.93, 0.86, 0.8, 0.73, 0.67, 0.6, 0.53, 0.47, 0.4, 0.33, 0.26, 0.2, 0.13, 0.07 and 0.0. So a level 15 tool becomes unbreakable.

With min_bits=6 a level 15 tool must break 1,048,576 nodes (2,097,152 nodes for min_bits=7). Max level can be decreased to 10 and only require 32,768 or 65,536 nodes. Or it could be increased to 20 and require 33,554,432 or 67,108,864 nodes. Quite flexible.

Okay, that seems to have took some effort. Thanks for your input.

There were some previous attempts at more levels on GitHub, but they aren't very much liked by server admins. 6 levels seems to be the best possible amount.

Only thing I might change is the number of nodes needed for levels. It doesn't take long for level 6 right now.

I haven't looked at the rest of the toolranks code but would it be possible to show something like "next level at N nodes" in the tooltip? It would let the player know if another level exists and how many nodes are needed to reach it.

There were some previous attempts at more levels on GitHub, but they aren't very much liked by server admins. 6 levels seems to be the best possible amount.

The new code below has an additional unbreakable_level setting that can be same as or higher than max_level. It controls the actual scale of the wear multiplier while max_level < unbreakable_level disables unbreakable tools.

With bits=7, max=5 and unbreakable=15 you get 6 levels with similar node counts but more balanced wear multipliers. Bumping max_level to 9 adds 4 more levels with level 9 requiring 32768 nodes and giving the same 0.4 wear multiplier your current level 6 gives. Bumping min_bits to 8 would double all the node counts. It allows admins to easily tweak node count and wear multiplier scales, and add more levels. It even has a debug mode to see the values for each level.

Code: Select all

lvl     nodes      wear multiplier
0       0          1
1       128        0.93
2       256        0.87
3       512        0.8
4       1024       0.73
5       2048       0.67  (current level 2 gives this wear)

6       4096       0.6
7       8192       0.53
8       16384      0.47
9       32768      0.4  (current level 6 gives this wear)

Code: Select all

toolranks = {
  -- these three settings can be tweaked by the server admin
--  min_bits = 6, -- 64 nodes to get level 1
  min_bits = 7, -- 128 nodes to get level 1
--  min_bits = 8, -- 256 nodes to get level 1
  max_level = 6,
  unbreakable_level = 15,
  debug = false -- set to true to view node counts and wear multipliers for each level
}
if toolranks.max_level > toolranks.unbreakable_level then
  minetest.log("error", "[toolranks] max_level("..toolranks.max_level..") must be less than or equal to unbreakable_level("..toolranks.unbreakable_level..")")
  toolranks.max_level = toolranks.unbreakable_level
end
toolranks.min_nodes = math.pow(2, toolranks.min_bits)
toolranks.max_level_nodes = math.pow(2, toolranks.max_level+toolranks.min_bits-1)

function toolranks.get_level(uses)
  if uses < toolranks.min_nodes then return 0 end
  if uses >= toolranks.max_level_nodes then return toolranks.max_level end
  return 1 + math.log(math.floor(uses / toolranks.min_nodes)) / math.log(2)
end

-- the level>1 check is not needed
local wear = digparams.wear * (1 - (level / toolranks.unbreakable_level))

-- or maybe get rid of debug setting and always display this info, without the error message
if toolranks.debug then
  print("[toolranks] DEBUG", toolranks.get_level(0), 0, 1)
  for i=1,toolranks.max_level,1 do
    local nodes = math.pow(2, i-1+toolranks.min_bits)
    -- current wear multiplier
--    local wear = 1 / (1 + (i+1) / 4)
    -- new wear multiplier
    local wear = 1 - (i / toolranks.unbreakable_level)
    print("[toolranks] DEBUG", toolranks.get_level(nodes), nodes, wear)
  end
  minetest.log("error", "[toolranks] DEBUG enabled")
end

First of all, thank you for your interest in my mod, and for the effort of improving it. I know more levels sounds good to multiple players, but I'd like to keep this mod simple. The code looks good and is probably a lot cleaner then mine. I also don't think forum is a good way for developer communication, so I'd appreciate it if you could make a pull request next time.

I run into this error whenever i try to play with this mod. I changed the name of the folder to toolranks, and i DID launch the game, but whenever I broke any node it instantly crashed the game. Any ideas? :(

[kingoscargames]

You are using a outdated minetest version so try updating that.

make a blank file called--> mod.conf
open it with a text editor and write this:

Code: Select all

name = toolranks

place your new mod.conf file
inside the mod folder (next to the init.lua file)
and see if it helps

edit: never mind.
why do you have that screen shot if you know that's not the problem?

yeah...what he said :)

Rename the mod dir to 'toolranks'

You've got outdated minetest, as others already said. It is wise to update at least when a new release is out.

Kill me

Sure thing.

[ToyElf]

Yup, updating fixed it, thanks! I didn't even realise i was using an outdated version >_> Cheers guys!

Sure thing.

will help too! a little bucket of lava?

I am honored to warrant a custom MS paint artwork, good sir.

that not mein work, found it on image sections xD i'm better at drawing (hmm wait no, it would be worst.)

I had an issue, game said:

I don't see how could that happen. There is a check to prevent it.
1. What mods have you got enabled?
2. What is your MT version?
