Nice!

[Doc]

Thanks! I have little ideas, and I make em into a quick mod. Eventually, I want to make a big mod though.

Instead of crafting the individual chains you may like this:

Code: Select all

function chain(pos, node)
if node.name == "chains:chain_top" then
minetest.env:add_node(pos.x,pos.y-1,pos.x{name="chains:chain"})
minetest.env:add_node(pos.x,pos.y-2,pos.x{name="chains:chain"})
minetest.env:add_node(pos.x,pos.y-3,pos.x{name="chains:chain"})
end
end
minetest.register_on_placenode(chain)

What it does is when chains:chain_top is placed, 3 chains are added underneath it.

[Doc]

Yeah, that sounds like a good idea. I still want there to be the ability to place single chain tops though. This gave me the idea of a chain roll item which uses this function! Perhaps I will add something like this in the next version or so. Thanks for the idea!

[VanessaE]

InfinityProject, you'll also need to check for the presence of air just before each of those add_node() calls, otherwise you could easily end up replacing dirt, stone, or part of a building.

[Doc]

Thanks VanessaE,
I was just about to borrow this code. I will be sure to add this.

Edit:
Here is my code:

Code: Select all

minetest.register_craftitem("chains:roll", {
    description = "Roll of chains",
    inventory_image = "Chains_roll.png",
    on_place_on_ground = function chain(pos, node)
            
            if node.name == "default:air" then
            minetest.env:add_node(pos.x,pos.y-1,pos.x                    {name="chains:chaintop"})
            end
            if node.name == "default:air" then
            minetest.env:add_node(pos.x,pos.y-2,pos.x                    {name="chains:chain"})
            end
            if node.name == "default:air" then
            minetest.env:add_node(pos.x,pos.y-3,pos.x                    {name="chains:chain"})
            end
}),

I think I am doing something wrong on check for air... Can someone fix my code? This is basically an item that places chain when you use it.

Edit: Actually, I think I am doing this all wrong. Please help me out!

First off you need to take a look at your register with minetest. Do you want the roll to act like a node where it is placeable like dirt or stone or do you want it to be treated much like placing a tool on the ground where it becomes an entity. Either one can be crafted by recipes but each has there own events that fires by minetest. I am not sure if on_place_on_ground is a registered event since I don't have the lua api with me since I am in class right now.

Moving into the code, with a event function you don't need to name it anything.

Code: Select all

trigger event = function(pos, node)

is acceptable.
To add a node to minetest

Code: Select all

pos = {x=value, y=value, z=value}

You have the correct function and node declaration just change the pos declaration.

Now how to actually accomplish what you want it to do. I would use a while loop to check if the node below is air and if it is then place a chain.
Pseudocode:

Code: Select all

incremented y value outside while loop
while(node below is air) then
  add chain
end

[Doc]

Thanks ashenk69! I will look at the api to see if there is that function or something similar. I essentially want it to be a minetest.register_craftitem that when right clicked on a block, it spawns a chain top and two or three chain below it.

Edit: I found on_place... will this work for what I need, and is pointed_thing a pos item that can be accessed with pointed_thing:x, y, z?

[Doc]

I have tried many things, but I just can't get it to work. Oh well, maybe later. For now I updated with chandeliers!

[webdesigner97]

Looks cool!

[Doc]

Thanks!

Overall- EPIC! The chandelier looks a little derpy though, maybe check out my Simply Candles mod for a slightly less derpy, however weedy and small looking chandelier. Still, epic mod!

Another thing, a suggestion. Maybe horizontal chains that can be used to cross lava, for example.

I have uploaded this mod with horizontal chains (they really work!) at:
https://www.dropbox.com/s/46sucqgmrqdwkhs/chains.zip

They go up diagonally like rails too!

My test code:

Code: Select all

minetest.register_node("chains:horizontalchain", {
    description = "Horizontal Chain",
    walkable = false,
    climbable = true,
    sunlight_propagates = true,
    paramtype = "light",
    drops = "",
    tile_images = { "Horizontal_chain.png" },
    drawtype = "raillike",
    groups = {cracky=3},
    sounds =  default.node_sound_stone_defaults(),
    })

Note: they don't connect properly at corners, but in real life a hanging chain would be straight anyway so it wouldn't matter.

There's the vines mod that also comes with a ropebox that auto-extends downwards. It has the drawtype plantlike and looks and works very well. I've wished for a horizontal version of that for some time.
