[Mod] Chess [1.0] [chess]

[Bas080]

A mod where you have nodes with which you can make a chess board and chess peaces and play chess

Made possible by
Bas080 - Project initiator and developer
Tonyka - 3D model designer
Rubenwardy - Developer

NEW FEATURE!!!
Node ownership
1. Only the placer of the chess spawner can also remove it. (admin)
2. After placing the spawn spawner, all players are prompted to hit the king of his/her desired color if he/she want's to play. This can be the admin or another player.

Recipe also changed because mese is gone:
W=wood
T=tree
WTW
TWT
WTW

Made textures 16x16

If one wanted to, it's easy enough to create lua entities. Actually coding game rules can be tricky. Off the top of my head, I recommend checking DreamChess's archives for the models. Swipe code from 3danimals or something.

[tonyka]

I like playing chess, and therefore your idea

the chess pieces need not be the typical game, may have inspired minetest forms...

ideas of chess pieces:

rook = Dungeon Master
knight = cactus
bishop = a tree
queen = a golden apple
king = the cat nyan
pawn = a rat

[tonyka]

another idea is that the pieces could have some lighting,...

thus would be beautiful even night play...

[rubenwardy]

Good idea, the rule coding will be hardest

Also, what is the size?

Solution:

I suggest using a real sized board and
use a "door" spawn like thing so when you place a chess spawner block, the black and white appears around it

No Rules, Players can move the pieces around, but it is not determened if they have won, the players have to notice like in real life.
Maybe if you click the spawn block all the pieces go back to the original.

The "door" (chess box) idea is good. And hitting it to reset the chessboard really keeps the focus on the game and not the building and placing of the pieces. I consider it a "should have"

[InfinityProject]

An idea: a grid. Recognizes if pieces are on the grid. Now movement. Commands? Example: /move rook a8 to a7. Just an idea.

this is the minimum version for the shape of pawn

Nodebox pawn:

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("chess:pawn",
    {description = 'pawn',
    tiles = {"default_wood.png"},
    drawtype = "nodebox",
    sunlight_propagates = true,
    paramtype = 'light',
    paramtype2 = "facedir",
    light_source = 15, --max light is 18
    node_box = {
        type = "fixed",
        fixed = {
            {-0.2, -0.5, -0.3, 0.2, -0.4, 0.3},
            {-0.3, -0.5, -0.2, 0.2, -0.4, 0.3},
            {-0.1, -0.4, -0.2, 0.1, -0.3, 0.2},
            {-0.2, -0.4, -0.1, 0.2, -0.3, 0.1},
            {-0.1, -0.3, -0.1, 0.1, 0.2, 0.1},
            {-0.2, -0.1, -0.1, 0.2, 0.1, 0.1},
            {-0.1 -0.1 -0.2 0.1 0.1 0.2},
        },
    },
    selection_box = {
        type = "fixed",
        fixed = {-0.3, -0.5, -0.3, 0.3, 0.2, 0.3},
    },
    groups = {snappy=2,choppy=2,oddly_breakable_by_hand=2}
}),


other textures that suggest:
white pieces: default_lava.png
black pieces: default_water.png

not promise anything, but if I have some time, I'll do the rest of figures ...

Has anyone started coding this? we should set up a github page, i would like to help.

If you want me to setup the page, i can do

You have two light_source properties there.

hauch!!

certain
fix it in post ...

This line of the door node looks like the job:

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.env:add_node( pos,  { name = 'doors:door_wood_a_c', param2 = newparam } )

And to call 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

minetest.register_on_placenode( on_door_placed ) --Used to setup chess board
minetest.register_on_punchnode( on_door_punched ) --Used to reset board

Not sure about lua for loops, (i mainly do c++) but this is how i think it would work:

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

--In a function called on chess:spawn's placing

local x=0
local z=0
local color=0
for (x=1;x<9;x++) --To make 8 rows (9-1)
  for (z=0;z<8;z++) --To make 8 cols (8-0)
     pos=new position(x, -- , z)
     if color==0
           minetest.env:add_node(pos ,  chess:board_black )
     else
           minetest.env:add_node(pos ,  chess:board_white )
     end if
     color=1-color --Toggles color between 1 and 0.
  next
next

THIS CODE WILL NOT WORK - It's used to illustrate how it would be done

Spawn Block Crafting

What will the recipe be? could make it multistep so it becomes a collectors item

1) Black and white wool to look like a chess board in the craft menu

or

2) 3x3 Mese


Or combine for a long process:

To make spawn block

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

chesspiece,  chesspiece, chesspiece

chesspiece, chesspiece, chesspiece

chesspiece, chesspiece, chesspiece

And then furnace it.

To make chess piece

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

bwool, wwool, bwool
wwool, mese, wwool
bwool, wwool, bwool

* bwool : Black Wool

* wwool : White Wool

I'm happy to see that you and others are excited about this idea.

Rubenwardy, i don't mind not being the owner. I would however like to push code to the git.

My github name is also bas080. Please add me when you get the chance :)

A step ahead of you :)

Already added you




I think we should make it a collect able,

So it should have a long make process.

What do you think?

[Bas080]

What do you think?

I'm sorry... I made my own git... the way i did it makes it easier to test the mod. It works right away. I used the template you setup. The code that has been implemented is checkers board maker. Now the pieces... and later the rules to avoid illegal moves.

I like the co-op idea. Will make separate LUA file for pieces and later for rules and interaction.

Ok, you add me and tonyoka then

[Bas080]

Was thinking, should the chessboard spawn box check if the chessboard fits in the area before it it placed or should it carve out enough space(remove nodes that are in the way of the chessboard spawning).

I'm pro checking if enough place, if not do not spawn chessboard and display chat message "Not enough space to place chessboard and pieces." Then you should mine the box again and try it somewhere else.

That is good.

[TheLoLMan]

lol good

[tonyka]

I'm creating the rest of figures, in a few days I put the complete code ...

[tonyka]

still not very well use github, so I created a fork .. in mine ...
and I have added the rook ...

& my nick in github is "tony-ka"

Ok, do a pull request :)

I am great at playing chess, I'd love to help out.

Hey Jordach, you are free to implement functions to the chess mod. There is a git and many functions to still be programmed. I am now thinking about how to implement chess piece ownership. This should avoid other players interfering in ongoing matches. Also illegal moves and movement commands are still to be programmed.

[Jordach]

Cool, I'll see what I can do.

[tonyka]

when i finish all the pieces, could also create a frame decorated with nodebox ...

you like this idea?

[rubenwardy]

Sounds good, i was thinking about that :D

[tonyka]

ok, first I will focus on making the pieces, then think of the framework ...

to me it is very easy to draw nodebox ..
if you want something specific, give me a drawing or photograph and I reproduce it easily ...

hey tonyka, i have seen your pieces and they look really nice. I am however looking for a texture to visualize the 3d models better.

All pieces are easily distinguishable except the queen and king. I'm used to having a bigger cross on top of the king.

I agree that the frame(border?) has to have a different colour and look then the dark chessboard pieces. I don't see a necessity to make a 3d model for the border nodes, although if you have something cool in mind I am totally up for it.

Also i was planning to fit the spawn node in the border of the chessboard. That way you don't have a weird node popping out at one of the corners of the chessboard like we have now.
