Can a broken mod stuck in a loop cause insane server lag?

Can a broken mod stuck in a loop cause insane server lag?

Not only broken mods can cause infinite or very long loops. Often mod makers do mistakes they don't notice till they use their mod and find out that it doesn't work as it should (the reason why modders have to play enough minetest). I also have this problem sometimes, e.g. my scheduler (or sth like this) mod, which makes it possible to look at a exploding chunk consisting of 200x300x230 tnt and build a house at the same time without having lags, had the problem that the function couldn't be executed in the function passed by it (e.g. minetest.delay_function(4, minetest.delay_function, 2, some_func, some_param)), l found it out by testing and then fixed it: https://github.com/HybridDog/function_d ... 4748da8e37
if l didn't use the mod, l wouldn't have found the infinite loop bug l added without noticing it: https://github.com/HybridDog/function_d ... c6e5553260

the register_on_craft callbacks receive the old craft grid (from before crafting) and the inventory the craft is from. So you should be able to look at the hammer from the old craft grid and insert it back into the inventory with more wear.

You could do something similar to send the hammer to the player's inventory instead, since the callback will receive an ObjectRef to the player as another argument.

From what ive been able to search and find, I can't seem to locate very much information on the register_on_craft.
so I'm still not entirely sure how id go about using this, and what id write for it to function the way im intending. I know this sounds like im asking "hold my hand through the whole process" but i'm doing my best as a young learner to try and wrap my head around this, however the lack of information i'm able to find and piece together makes this troublesome and difficult to do without me asking silly question, such as these where they imply i need my hand held.

I think that Byakuren described that very well so if you do not understand any of that you should perhaps break it down and ask more specific questions like what is a callback or what is an ObjectRef, for example.

IMO, the best way to learn is to study other mods which interest you or have similar functionality to something you want to do. I would also recommend this as good resource for anyone wishing to learn about modding online book teaching how to mod There is of course the official doc's and developer wiki which you should have bookmarked already ;-)

Hi all,

I've been trying to get water out of a stone... oh, ok, a node... ;-) All I need is for code that lets me do stuff if punched / clicked (I don't really care either way) with an empty bucket.

I found this in the well mod:

if minetest.get_modpath("bucket") then
local original_bucket_on_use = minetest.registered_items["bucket:bucket_empty"].on_use
minetest.override_item("bucket:bucket_empty", {
on_use = function(itemstack, user, pointed_thing)
local inv = user:get_inventory()

if pointed_thing.type == "node" and minetest.get_node(pointed_thing.under).name == "homedecor:well" then
if inv:room_for_item("main", "bucket:bucket_water 1") then
itemstack:take_item()
inv:add_item("main", "bucket:bucket_water 1")
else
minetest.chat_send_player(user:get_player_name(), "No room in your inventory to add a filled bucket!")
end
return itemstack
else if original_bucket_on_use then
return original_bucket_on_use(itemstack, user, pointed_thing)
else return end
end
end
})
end

But obviously it's not all I need as this creates a nill value error on bucket:bucket_empty on startup.

What am I missing? TIA!

[KzoneDD]

NVM... I had hoped to put off the time when forgetting my 'depends' became an issue, but it's here. ;-) Forgot to declare bucket. :-P

e^(-b) = 2*e^(-b*d)-1

e and d are known, b is not 0. How can l shift the equation to get b?

[iangp]

e^(-b) = 2*e^(-b*d)-1

e and d are known, b is not 0. How can l shift the equation to get b?

From where do you get this relation?

e**-b == 2*e**(-b*d) - 1

[Hybrid Dog]

http://freespace.virgin.net/hugo.elias/ ... posure.htm

v(x) = a*[1-e^(-b*x)]

x is in [0, 1], 0 means black, 0.5 means middle grey and 1 means white
d is the middle brightness of the picture (the expectation), so it's also inside [0, 1]
a and b are not 0

v(0) = 0; → a*[1-e^(-b*0)] = 0; → 1-1 = 0;
v(1) = 1; → a*[1-e^(-b)] = 1
v(d) = 0.5; → a*[1-e^(-b*d)] = 0.5

1/[1-e^(-b)] = 0.5/[1-e^(-b*d)]; → 2*[1-e^(-b*d)] = 1-e^(-b); → 1-2*e^(-b*d)] = -e^(-b);
e^(-b) = 2*e^(-b*d)-1

[iangp]

e^-b = 2*e^(-b*d)-1
derive both sides
-e^-b = -2*d*e^(-b*d)
multiply by -1 both sides
e^-b = 2*d*e^(-b*d)
apply "ln" as a operation on both sides
ln e^-b = ln [2*d*e^(-b*d)]
logarithm properties log (a*b) = log a + log b
-b = ln 2 + ln d - b*d
b-b*d = ln 2 + ln d
b (1-d) = ln 2 + ln d
Finally
b = (ln 2 + ln d) / (1 - d)
Check out please I'm not sure

It doesn't work:

deriving is a nice idea but
call the left side l(b) and the right side r(b)
l(b) = r(b)
the derivation gives the pitch of the function, but l and r are just equal at b, which is fixed, so l'(b) doesn't need to be r'(b)

Maybe you need to use the W function to shift it for b

I just had this idea cause the (-1) was pissing me off after a while trying shift the equation hehe and d/dx(constant) = 0, a perfect murder hehe, unfortunately doesn't work in this case.

I just learned Calculus I (limits, derivatives and integrals, with just one variable and at IR) and I need more practice, but I'll try understand W function in somewhere else.

l didn't know derivations with more than one variable are possible.

[iangp]

partial derivatives of functions that have more than one variable.
https://en.wikipedia.org/wiki/Partial_derivative
And derivatives of vectors, I see that like "more than one variable" (in this case axis), gradient and others operations
https://en.wikipedia.org/wiki/Gradient

the point is I'm just getting started at this new stage of mathematics :P
This is probably getting off-topic it's better we finish it here.

I have a question!
I want to override ore generation of other mods. Thus i can use "minetest.clear_registered_ores()". But how i can control mod load order? Does it depends from mod name?

[paramat]

the 'depends.txt' file controls mod order.

[Foghrye4]

Thank, paramat.

Do mesh objects have a cuboid collision box or a complex one?

[Don]

You set the collision box like a nodebox.

Hi,
I'm trying to create block similar to furnace but more like "item converter". Due this reason I cannot use regular "fuel" recipes (I want that items as "fuel" would work only on my block).

So far I decided go ABM route which would check item in "fuel" slot and add it as fuel time manually according some predefined rules. To do so I need "extract" fuel name from fuel slot (it will be multiple custom "fuels").

I take furnace as example

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_abm({
  action = function(pos, node, active_object_count, active_object_count_wider)
    local meta = minetest.get_meta(pos)
    local inv = meta:get_inventory()
    local fuellist = inv:get_list("fuel")


Seems I getting list of userdata objects. I do not know how to extract properties from them rather than guessing. Unfortunately minetest dev wiki and lua api documentation does not provide explanation about userdata (or I missed?).

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

{ <userdata 1> }

Maybe I did completely wrong and I need go another direction?

[xeranas]

guessing over

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

userdata:get_name()

Still where I could find which properties I can get from userdata? Maybe we can add some notes in dev wiki or lua api to help newbies like me?

[Byakuren]

They are a list of ItemStack. You can find the methods available in the mod API doc.

[xeranas]

Thanks!, I was bit confused because lua.api documentation does not explicity says which type of objects from list I should expect. InvRef get_list

get_list(listname): return full list

you called the mod folder unifiedinventory, but you need to call it unified_inventory

About the method:

Code: Select all

minetest.register_decoration()

How I can set a quantity of generated items?

[MineYoshi]

Exactly how i can stop this function with other use?

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_tool("headphones:1headphones", {
   description = "Headphones Test Song",
   inventory_image = "testh.bmp",

   on_use = function()
      minetest.sound_play("test")
   end,
   
      
})

I mean i click one time, plays the sound, i click other time, the song plays again with the other.
I want to do this, i click one time, plays the sound, i click again and the stops the sound, how i do that?
