Issues with Porting Rope Mod

PostPosted: Tue Jan 31, 2012 01:49

Trying to port the Rope mod to work with ItemDef. Although it is functional now, I'm having trouble removing the rope from the player's inventory after placing a rope. Here is the 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.

-- Rope mod. By Mirko K.
--
-- Three tree block in a vertical row = 9 meter of rope.
-- Placement automatically adds rope downwards until it runs out or some
-- non-air block is in the way.
-- Push (single left-click) cuts the rope at that position. Digging removes
-- the whole rope.

Does anyone know what I'm doing wrong?

The intent is that when n rope blocks are placed, it should remove n rope items from the inventory, is that right?

PostPosted: Tue Jan 31, 2012 04:21

Yes, that is correct.

Specifically, the issue is with the place_rope function, where it says digger:get_inventory():remove_item...". It doesn't seem to remove the item no matter what I try.

Yes, it's a design limitation in itemdef, on_placenode can't modify the wielded item. But you could redefine the more low-level (and more complicated) on_place callback, untested:
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

-- remove the register_on_placenode call

...

place_rope = function(itemstack, placer, pointed_thing)
    if pointed_thing.type == "node" then
        -- Calculate wall-mount direction
        local under = pointed_thing.under
        local above = pointed_thing.above
        local dir = {x = under.x - above.x, y = under.y - above.y, z = under.z - above.z}
        local param2_wallmounted = minetest.dir_to_wallmounted(dir)

        local pos = above
        local oldnode = minetest.env:get_node(pos)
        local olddef = ItemStack({name=oldnode.name}):get_definition()

        while olddef.buildable_to and not itemstack:is_empty() do
            minetest.log("action", placer:get_player_name() .. " places rope "
                .. " at " .. minetest.pos_to_string(pos))

            -- Place the rope
            local newnode = {name = "ropes:rope", param1 = 0, param2 = param2_wallmounted}
            minetest.env:add_node(pos, newnode)
            itemstack:take_item()

            -- if you want, call all callbacks in minetest.registered_on_placenodes here
            -- see minetest.item_place_node in builtin.lua

            -- Go down
            pos.y = pos.y - 1
            oldnode = minetest.env:get_node(pos)
            olddef = ItemStack({name=oldnode.name}):get_definition()
        end
    end
    return itemstack
end

...

minetest.register_node("ropes:rope", {
    ...
    on_place = place_rope,
    ...
})


There are some more or less important differences: first, the rope extends to anywhere that is buildable, in particular into water and other liquids. If you don't want that, simply replace the check for buildable_to with a check whether oldnode.name == "air". Second, if a stack of (let's say) 10 ropes is in your hand and another stack of 5 somewhere else in the inventory, the rope will only go down up to 10 nodes, unlike before where it tried to place all 15.

'furnace_burntime = 5,' is deprecated:
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_craft({
    type = "fuel",
    recipe = "ropes:rope",
    burntime = 5,
})


And you don't need the extra quotes in the output:
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_craft({
    output = 'ropes:rope 9',
    recipe = {
        {'', 'tree', ''},
        {'', 'tree', ''},
        {'', 'tree', ''},
    }
})


Also, I use papyrus instead of wood for the crafting recipe, but whatever.

@kahrl: thanks, that worked great!

Seems like the folks behind RTMMP have added these changes in already:

https://github.com/Hackeridze/ru-true_minetest_mods_pack/blob/3cf6124538d42debe725f4e499454542613f96eb/src/ropes/init.lua

I'll see what I can do about adding randomproof's suggestions.

Edit: Here is the new version:

Why not junglewood or leaves and jungle wood
While this topic is here i was trying to update the secret passages and fix a spelling error i noticed but its having trouble around the register craft area help would be liked

@sdzen:

Your top recipe is incorrect is should be:

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_craft({
    output = 'secret_passage:component',
    recipe = {
        {'default:glass', 'default:glass', 'default:glass'},
        {'default:dirt', '', ''},
    }
})


You where missing the two empty fields on the 2nd row, because you use all 3 fields on the top row you must make sure you add all 3 fields to each row there after.

I noticed that the remove_rope() function never removes the rope at pos.y, only above and below it. Also, when you dig a node it gets punched and so the function is never passed a true value for completely. I also wanted to support the vine-like rope from moreblocks, and use cotton from flowers or wool (or curtains) in the recipes, instead of wood or papyrus. So, I modified the code:
