I know this doesn't have to do with mods, but how large is a chunk(otherwise known as block)? And how can I tell that I am on the edge of a chunk?

[jojoa1997]

For the first question it is 16*16*16

16³

for the second question, it's just easy math:

Code: Select all

local pos = player:getpos()
local relpos = { x=pos.x % 16, y=pos.y % 16, z=pos.z % 16 }
if relpos.x <= 1 or relpos.x >= 15 or relpos.y <= 1 or relpos.y >= 15 or relpos.z <= 1 or relpos.z >= 15 then
  -- I am at the edge
else
  -- I am not
end

EDIT: Adjust values as necessary.

As jojoa said, a mapblock is 16x16x16 nodes. However, the map generator always generates 5x5x5 mapblocks at once.

To see if you are at the edge of the mapblock just look at the animation of lava. It is by default not synced (there is a setting for that in minetest.conf), so you can see the mapblock borders.

Somehow you didn't strike me as someone who would get excited about your post totals.

Good jorb, Adam. Good jorb.

why do mapblocks generate 5*5*5 and not 16*16*16

Here is something I was working on. What I want is a cauldron that fills with water when right clicked with a bucket of water. I tried this but it doesn't work. Here is the code:

Code: Select all

minetest.register_node("thaumtest:cauldron_full",{
    drawtype="nodebox",
    paramtype = "light",
    tiles = {"default_wood.png"},
    groups = {choppy=2},
    node_box = {
        type = "fixed",
        fixed = {
            {-0.500000,-0.375000,-0.500000,-0.375000,0.500000,0.500000}, 
            {0.375000,-0.375000,-0.500000,0.500000,0.500000,0.500000},

I thougt it would be nice if you could change stack_max using a setting. So game-modes could use minetest.config instead of overwriting.

This is my first try, but it is not working at all:
in builtin/item.lua line 376

Code: Select all

--
-- Item definition defaults
--
local stack_max = 99
if tonumber(minetest.setting_get(stack_max)) then
    stack_max = tonumber(minetest.setting_get(stack_max))
    print("[builtin] stack_max = ".. tonumber(minetest.setting_get(stack_max)) .."")
end

minetest.nodedef_default = {
    -- Item properties
    type="node",
    -- name intentionally not defined here
    description = "",
    groups = {},
    inventory_image = "",
    wield_image = "",
    wield_scale = {x=1,y=1,z=1},
    stack_max = stack_max,
-- . . .

@Evergreen
You need to add a , at the end of the on_rightclick and the nodebox.

[Evergreen]

Tried it and it still doesn't work. Code:

Code: Select all

-code-

It is caused by the bucket mod. -> https://github.com/minetest/minetest_ga ... it.lua#L42

When it is changed to on_use() [in bucket mod] it works fine.
^
Edit: Casimirs solution is better (to use on_punch()).

And it has to be

Code: Select all

  minetest.env:set_node(pos, {name="thaumtest:cauldron_full"})

[Casimir]

Now working:

Code: Select all

local stack_max = 99
if minetest.setting_get("stack_max") then
    stack_max = minetest.setting_get("stack_max")
end

Please interpret this as a pullrequest

@Evergreen
You will encounter an additional problem. The bucket is not calling the on_rightclick function of nodes, it will just place the water. You could use on_punch.
Edit: BlockMen was faster

[Evergreen]

  on_rightclick = function(pos, node, clicker, itemstack)

    end

I looked in the debug, and that is supposed to be there. EDIT: nvm

Soon it will not be minetest.env:set_node it will be minetest.set_node. Just something to think about.

Thanks, it works now. The next problem is to empty the bucket when the cauldron is punched. (don't answer this until I have a problem)

he was using on_rightclick, not on_punch.

minetest.env:replace({item="bucket:bucket_empty"})

wat

Edit:
just do:

Code: Select all

local inv = puncher:get_inventory()
inv:remove_item("main", itemstack)
itemstack = ItemStack("bucket:bucket_empty")
inv:add_item("main", itemstack)
player:set_wielded_item(itemstack)

Edit 2:
Scratch that, I missed the earlier post about the bucket mod not calling on_rightclick.

[BlockMen]

I have a problem. I tried to do this:

Code: Select all

on_punch = function(pos, node, puncher)
        if puncher:get_wielded_item():get_name() == "bucket:bucket_water" then
            minetest.env:set_node(pos, {name="thaumtest:cauldron_full"})
            minetest.env:replace({item="bucket:bucket_empty"})
        end
end,

Just set the wieleded item :

Code: Select all

on_punch = function(pos, node, puncher)
        if puncher:get_wielded_item():get_name() == "bucket:bucket_water" then
            minetest.env:set_node(pos, {name="thaumtest:cauldron_full"})

end,

Nope. he changed after the suggestion of Casimir

[Evergreen]

Thanks everyone! It works now. Idk what I would do without this topic.

[Evergreen]

I am running in to a problem. I want to do the same thing as I did before, except it empties the cauldron into the bucket this time. My problem is that you can't punch anything with an empty bucket. The reason you can't punch anything, is that the only thing you can punch with an empty bucket is water. Since I am using "on_punch" to detect when to take the water out of the cauldron, it doesn't work. Can anyone suggest a workaround for this?

[SilverFlame]

I need help installing mods..i tried several times and it didnt work. is there a specific way of doing it instead of just downloading and temoving it from the file?

Do you use stable 0.4.6? --> http://forum.minetest.net/viewtopic.php ... 510#p88510

If you use the latest github version(s) --> http://forum.minetest.net/viewtopic.php ... 221#p91221
--> don't forget to 'activate' them with configure

Some other "Usual suspects" for mods (still) not working:
- A folder needs to be renamed to the (low-case) name, used in the init.lua.
Example: VanessaE-homedecor-e5c99a3 --> rename --> homedecor
- Trying to use an older mod version or a not up to date mod version
- Use of an older version of minetest than the latest, unofficial
- Missing dependencies (look in the 1st post of a mod or check the depends.txt file in the mod folder you installed)
- Bugs in a mod
