When I googled for it, I found a response from MVRDV where they claim to have not intended it to look like 1/2 WTC, but what I found rather incredible is that they claimed to not even recognize the similarity (I figured most of the world saw those images, it was a pretty big event).

Hmm i wonder if some idiots have actually complained the design is in bad taste? Almost certainly :)
I see things the other way around ... due to 9/11 people are now making associations whenever they see 2 towers with something happening part way up.
I'm very much into modern architecture and MVRDV are one of my favourite design studios. Some of their stuff looks suitable for generative architecture techniques.

I have to give points to MVRDV though, this is the most complicated thing i've built yet, I can't imagine what the real thing will be like to build.

Windows are done (several 1K stacks lol) - still got fix internal walls in the "cloud" part, do the balconies and rooftop terraces with greenery, two stairwells and get rid of those shadows. The next project will be simpler :p

I tried it myself and it took more like 20 seconds. Here is the relevant code:
Code: Select all
        local vm = minetest.get_voxel_manip()
        local p1, p2 = vm:read_from_map(
            {x=-IRON_TNT_RANGE+pos.x, y=-IRON_TNT_RANGE+pos.y, z=-IRON_TNT_RANGE+pos.z},
            {x=IRON_TNT_RANGE+pos.x, y=IRON_TNT_RANGE+pos.y, z=IRON_TNT_RANGE+pos.z}
        )
        local va = VoxelArea:new{MinEdge=p1, MaxEdge=p2}
        local data = vm:get_data()
        for x=-IRON_TNT_RANGE,IRON_TNT_RANGE do
        for y=-IRON_TNT_RANGE,IRON_TNT_RANGE do
        for z=-IRON_TNT_RANGE,IRON_TNT_RANGE do
            if x*x+y*y+z*z <= IRON_TNT_RANGE * IRON_TNT_RANGE + IRON_TNT_RANGE then
                local i = va:index(pos.x+x, pos.y+y, pos.z+z)
                --activate_if_tnt(data[i], {x=pos.x+x,y=pos.y+y,z=pos.z+z}, pos, IRON_TNT_RANGE)
                data[i] = c_air
            end
        end
        end
        end
        vm:set_data(data)
        vm:write_to_map()
        vm:update_map()

Make sure that c_air is defined.
Also the mapblock sending takes long, you are faster when you just rejoin the server (or restart singleplayer).

A "small" part to a much larger project that I hope to complete some time soon. EDIT! I've come to the conclusion that this'll take a week or so. There's going to be four towers, each comprised of seven layers and a glass roof. The seven layers will be as followed:

22 blocks
20 blocks
18 blocks
16 blocks
14 blocks
12 blocks
10 blocks

...And then each tower will be capped by triangular, obsidian glass roof. The four towers will be connected by halls that will be eighty-six blocks in length...at an unknown height of blocks. I have no idea what'll be in the center of this.

It looks like you are using the building_blocks mod. There is a newer version of it out than what you have. You might want to get it.

Your project looks like it could be interesting.

Due to it looking a bit thin, I think I'm going to bump it up to seven towers instead of the original four. This is just a skeleton of the first tower, just to give an idea of what it'll look like.

Make sure that c_air is defined.
Also the mapblock sending takes long, you are faster when you just rejoin the server (or restart singleplayer).

this is my code:
Code: Select all

                if r <= radius then
                    local np={x=pos.x+x, y=pos.y+y, z=pos.z+z}
                    local n = minetest.env:get_node(np)
                    if n.name ~= "air"
                    and n.name ~= "default:chest" then
    --                and math.random(1,2^rad) < range*8 then
                        if math.floor(math.sqrt(r) +0.5) > range-1 then
                            if math.random(1,5) >= 2 then

                                    nodes[area:index(np.x, np.y, np.z)] = c_air
                                end
                            elseif math.random(1,10) == 1 then
                                minetest.sound_play("default_glass_footstep", {pos = np, gain = 0.5, max_hear_distance = 4})
                            end
                        else
                            destroy_node(np)
                            if minetest.env:get_node(np).name ~= "default:chest" then
                                nodes[area:index(np.x, np.y, np.z)] = c_air
                            end
                        end
                    --[[elseif n.name == "default:chest" then
                        local p = np
                        while minetest.env:get_node({x=p.x, y=p.y-1, z=p.z}).name == "air" do
                            p.y=p.y-1

                        end

                        minetest.env:add_node(p, {name="default:chest"})
--                        copy_meta(np, p)
                        minetest.env:remove_node(np)

                        --minetest.env:get_meta(minetest.env:get_meta(pos))]]
                    end
                    activate_if_tnt(n.name, np, pos, range)
                end
            end
        end
    end
    manip:set_data(nodes)
    manip:write_to_map()
    print(string.format("[nuke] exploded in: %.2fs", os.clock() - t1))
    local t1 = os.clock()
    manip:update_map()
    print(string.format("[nuke] map updated in: %.2fs", os.clock() - t1))
end

So it's not necessary to set ignore everywhere?

You do have too much code in the time critical part.
Calling get_node() in there makes it a lot slower.
What does destroy_node() do? If it removes the node at the position then its not needed at all. Setting another value in the data of the vmanip is enough to replace a node.
I dont know how sound_play() behaves, it might be too slow.

So it's not necessary to set ignore everywhere?

You do have too much code in the time critical part.
Calling get_node() in there makes it a lot slower.
What does destroy_node() do?
It's used to preserve the items which would be dropped (I disabled it so it did nothing.):
Code: Select all
local function describe_chest()
    if math.random(5) == 1 then return "You nuked. I HAVE NOT!" end
    if math.random(10) == 1 then return "Hehe, I'm the result of your explosion hee!" end
    if math.random(20) == 1 then return "Look into me, I'm fat!" end
    if math.random(30) == 1 then return "Please don't rob me. Else you are as evil as the other persons who took my inventoried stuff." end
    if math.random(300) == 1 then return "I'll follow you until I ate you. Like I did with the other objects here..." end
    return "Feel free to take the nuked items out of me!"
end



local function set_chest(p) --add a chest if the previous one is full
    local pos = p
    while minetest.env:get_node({x=pos.x, y=pos.y-1, z=pos.z}).name == "air" do
        pos.y=pos.y-1
    end
    minetest.env:add_node(pos, {name="default:chest"})
    local meta = minetest.get_meta(pos)
    meta:set_string("formspec",default.chest_formspec)
    meta:set_string("infotext", describe_chest())
    local inve = meta:get_inventory()
    inve:set_size("main", 8*4)
    nuke_chestpos = pos
end

local function destroy_node(pos)
    if nuke_preserve_items then
        local drops = minetest.get_node_drops(minetest.env:get_node(pos).name)
        if nuke_drop_items then
            for _, item in ipairs(drops) do
                if item ~= "default:cobble" then
                    minetest.env:add_item(pos, item)
                end
            end
        elseif nuke_puncher ~= nil then
            local inv = nuke_puncher:get_inventory()
            if inv then
                for _, item in ipairs(drops) do
                    if inv:room_for_item("main", item) then
                        inv:add_item("main", item)
                    else
                        if nuke_chestpos == nil then
                            set_chest(pos)
                        end
                        local chestinv = minetest.get_meta(nuke_chestpos):get_inventory()
                        if not chestinv:room_for_item("main", item) then
                            set_chest(pos)
                        end
                        chestinv:add_item("main", item)
                    end
                end
            end
        end
    end
end

Maybe math.random causes the lags.
Is it faster if I use PseudoRandom?

math.random() shouldnt be a problem, you should rather not use minetest.get_node() at all. You could instead check the content ID of the chest.
