Beautiful.

I love that invert explosion. Not sure what the 3rd screenshot is. Are you going to nuke the meru tower?

[PilzAdam]

I edited the nuke mod and made a big hole with vm (it took ca. 8min) (r=120):

8 minutes? oO
I tried it myself and it took more like 20 seconds. Here is the relevant code:

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

        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.

I'll look into updating and downloading that mod then as soon as possible.

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.

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.

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.):

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

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.

I have to say that I would never go into these crazy buildings in real life. They may be safe but they look like a horrible place to spend time. One good earthquake or explosion and down they come. A regular building could also succumb to an earthquake or explosion but these just look far more fragile.

[Casimir]

Those buildings must comply the same standards as all the others. So the have to be build as safe as "normal" buildings, but it is way more expensive to do so. The most effective shape for a skyscraper is a vertical tube, thats why this things look so strange - they are very uneffective.

Thanks, that uses what Bas080 used for the leaves in the OCD game, 'use_texture_alpha = true' in the node definition and editing the alpha channel of the texture to be lower than 255.
I made my leaf nodes semi transparent with an alpha of 239 and 'drawtype = glasslike', they cetainly are glitchy ... water normally obscured by a node shines right through, making the leaves flicker-invisible ... also multiple layers of other semi transparent nodes become brighter with distance.
However i like the effect, it is like light flickering through trees, it also makes the leaf nodes seem less bulky, so i continue to use this. I have also been experimenting with 'drawtype = plantlike' for leaves, since they are foliage like other plants, again this reduces the visual bulk.
