How do I make grass cover more ground? The grass I'm talking about is the one that grows, not the grass_on_dirt kind. It's just the fields feel too flat and grass really helps make it look better but there is so little of them that spawns.

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

-- Determine grass amount from perlin noise
local grass_amount = math.floor(perlin1:get2d({x=x0, y=z0}) ^ 3 * 9)"

I'm not sure what to change exactly, but that's where you'd change it!

If you want grass to be more common add +X. If you want more grass, when there is grass increase *9 to a higher value. If you want grass to be distributed more equally remove ^3.
Or, you could use the new register_decoration.

p.s. Could someone of the more experienced developers take a look at fairiestoys code?

does anyone know how to make a crafting table, but with different properties? I want to make an anvil to forge armor and crossbows in castles+

EDIT: When you place a chest-like item, can you make it so it already contains a set of steel tools.

Do you mean something like mentioned here:

( you have to scroll nearly to the end of the first post ). Maybe a look into the source of this could help you.

Edit:
To your second question. If you take the code from the default chest:

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

on_construct = function(pos)
        local meta = minetest.get_meta(pos)
        meta:set_string("formspec",default.chest_formspec)
        meta:set_string("infotext", "Chest")
        local inv = meta:get_inventory()
        inv:set_size("main", 8*4)
    end,


And insert something like inv:add_item( 'main', ItemStack ) (where ItemStack is your defined Itemstack respectively), it should work i think (untested)

You get this error, because you made a typo related mistake. You wrote

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

inv::add_item( 'main', "default:steel_sword" )

And it should be without the double ':' . And this error is not related to the modified chest code. If you take a closer look at the error code (

) it nearly tells you what is wrong. This is how the code for the chest looks like.

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

on_construct = function(pos)
        local meta = minetest.get_meta(pos)

                 "list[current_player;main;0,5;8,4;]")
         meta:set_string("infotext", "Chest")
         local inv = meta:get_inventory()
         inv:set_size("main", 8*4)
        local IStack = ItemStack( 'default:pick_steel 1' )
        inv:add_item( 'main', IStack )
    end,


And if you didn't redefined the default tools, you should take a closer look at your itemstring. I suggest that you always keep a second file open with all default definitions you are using for quicker access. Could make development a bit easier ;).

What's a good programme for making animated entities? I looked at blender but it looks way too advanced, considering I only want to create basic objects (Made out of rectangles and lines) and also I have a limited knowledge of creating 3d objects.

It's either Blender or GTFO. There is no other option with entity mesh creation.

If you are looking for something free then I also suggest you stick with blender, there are plenty good tutorials on the net and it really is not that difficult to create simple blocky models for minetest.

Try:

//pos1

2)

//hollowsphere 5 default:dirt

[Element]

oh...ok thanks

[Element]

i tried it and my server still shut it self down

[LionsDen]

There are two versions of WorldEdit. The version before 1.0 (I think it is 0.6 or so) is for Minetest versions 0.4.7 and before while version 1.0 or above is for the latest github or build of Minetest. Trying to use version 1.0 on an older version of Minetest can cause crashes I have heard. I hope this was your problem because if so it is an easy fix.

There is this thing called “checkbox” in the formspecs now.

However, every time I click the checkbox, the on_player_receive_fields() is called, which is not exactly what I want. I also think it’s incosistent, because if I type in text in a field, on_player_receive_fields() is not called.

What I want is to make a simple dialog with checkboxes and an “OK” button_exit. The value of the checkbox shall be read after the OK button has pressed. I don’t care about the event of the user clicking the checkbox, I just want to read the value of the checkbox after OK has been pressed. The problem is, both button_exit and checkbox send on_player_receive_fields() which messes things up for me. I can’t tell wheather the player clicked the checkbox or the button_exit.

Questions:

• Why does on_player_receive_fields get called when the player clicks a checkbox?
• Can I prevent Minetest from doing that?
• Is there an alternative callback for button_exit?

[fairiestoy]

Wuzzy, it is possible to determine if the button has been pressed or the checkbox. Within the fields table you also have the name of the button as index. If you now make a check like

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

if fields.exit_button then
    --ongoing code
end


Where exit_button is the name of the defined button respectively.

According to your points (afaik):
> Because its an event which could be used to change the interface. Usually its not wanted that the interface
changes on simple text input
> Not afaik, but you could use the workaround mentioned in this post

Edit:
Example use of the checkbox events is seen in the client menu. If you would check the checkbox for public serverlist but don't send a event, you would wait very long for any changes to kick in.

Thanks this answers my question. :-)

Now for the next question:

There are methods for InvRef but I don’t get my head around the documentation. There is always this parameter called “listname” and the fact that it is written in double quotes in the wiki suggests that this must be a string.
Where does this strange “listname” come from? What name of which list? I have no idea what to put there. This is true for all InvRef methods.

Inventories consist of several lists, which consist of a number of slots.
Here are some exaples from the default minetest_game / engine that should explain it pretty good:

The default player has 3 lists:
"main": this is the main inventory, where the first 8 slots are displayed in the hotbar; the size is 8×4
"craft": the 3×3 crafting grid
"craftresult": the single slot for the craft result; has a special handling by the engine.

Chests only have one list, "main".

Furnaces have 3 lists:
"fuel": the single fuel slot
"src": the slot above the fuel (i.e. the item that will be cooked)
"dst": the result

[Wuzzy]

Thanks a lot! :)

There is actually a fourth list, craftpreview. The special handling needs both it and craftresult.

I'm not sure, but I could probably make one pretty easily. How far down should it be?

Is it possible to make a crafting table that only crafts on certain set of things. I want a castle:anvil to craft castle:armor_"item" but not like wood, because an anvil only makes metal items like armor, not trees into planks...

[fairiestoy]

Hey everybody,

a little question, since i couldn't find anything related to that. Is it possible to run Lua Code Ingame with the minetest namespace? Like opening a formspec, type in your code and execute it. It would increase the development of formspec design for example a bit ( at least for me ).

Greetings...
