[Mod] Hatches [hatches] (missing license)

[ironzorg]

Hello everyone.

Not much to be said, the title is pretty much self explanatory: I implemented hatches as a LUA mod.







When it's open, a trapdoor is climbable, and you can't go through it when it's closed (the upcoming version of minetest will allow me not to use the whole node as boundary box).

Sorry for the poor textures, feel free to make your own (I'm a terrible artist, although I felt like I had to release that mod with at least one texture).

Great mod! Thanks!

There's a small bug in it, when digging a placed hatch there seem to be two different types of hatch.
At least I've gotten two stacks that havent been combinable.

amazing!

[maddogg]

yes Fair play it will be good

Indeed, I'll look into it.

EDIT: It's fixed, I uploaded the new version of the mod.
What's changed:

• Fixed the boundary detection bug when placed an open hatch
• Fixed the compatibilty issue when harvesting an open/closed hatch
• Enhanced the boundary box of the closed hatch

I don't want to sound harsh, but all you did was disabling the climbable attribute of open hatches, which was there on purpose..

[Jeija]

Nice mod! May I use it for my mesecon mod, so that hatches can be controlled by mesecons?

[hurufu]

Great!
Could you put the texture to the upper side of block? So when you are walking on it, there were no empty space between you and visible texture.

Absolutely.

In fact this is due to a limitation of minetest's engine, actually I can't set the boundary box to be exactly the outline of the hatch.
We have to wait for the next release (with the stairs code if I'm not mistaken) so that I can be able to fix that. Also hence the climbable attribute.

Small request: When hatch is open, it has no collision (not walkable). When closed, it is climbable. It feels much better IMO :)

If it was climbable when open, you would be able to go through it. Moreover, it's climbable when it's open because of that boundary box problem (it makes much more sense).

I've changed it to work with the newest version of MineTest:

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 constants
-- This _has_ to be set to 2
local HATCH_OPENED = 2
-- This has to be != from HATCH_OPENED and is coded on 4 bits
local HATCH_CLOSED = 1

-- Local Functions
local on_hatch_punched = function(pos, node, puncher)
    if (node.name ~= 'hatches:hatch_closed')
        and (node.name ~= 'hatches:hatch_opened') then
        return
    end
    local state = node.param2

    -- Switch the hatch state when hit
    if state == HATCH_OPENED then
        node.name = 'hatches:hatch_closed'
        node.param2 = HATCH_CLOSED
    elseif state == HATCH_CLOSED then
        node.name = 'hatches:hatch_opened'
        node.param2 = HATCH_OPENED
    else
        print('Uninitialized node: ' .. state)
    end

    minetest.env:add_node(pos, {
        name = node.name,
        param2 = node.param2,
    })
end

local on_hatch_placed = function(pos, node, placer)
    if node.name ~= 'hatches:hatch_opened' then
        return
    end

    minetest.env:add_node(pos, {
        name = node.name,
        param2 = HATCH_OPENED,
    })
end

-- Nodes
-- As long as param2 is set to 1 for open hatches, it doesn't matter to
-- use drawtype = 'signlike'
minetest.register_node('hatches:hatch_opened', {
    drawtype = 'signlike',
    tile_images = {'hatch.png'},
    inventory_image = 'hatch.png',
    sunlight_propagates = true,
    paramtype = 'light',
    paramtype2 = "wallmounted",
    legacy_wallmounted = true,
    walkable = false,
    climbable = true,
    selection_box = {
        type = "wallmounted",
    },
    material = minetest.digprop_constanttime(1.0),
    drop = 'hatches:hatch_closed',
})

minetest.register_node('hatches:hatch_closed', {
    description = "Hatch",
    drawtype = 'raillike',
    tile_images = {'hatch.png'},
    inventory_image = 'hatch.png',
    wield_image = "hatch.png",
    paramtype = 'light',
    walkable = true,
    selection_box = {
        type = "fixed",
        fixed = {-1/2, -1/2, -1/2, 1/2, -2/5, 1/2},
    },
    material = minetest.digprop_constanttime(1.0),
})

-- Crafts
minetest.register_craft({
    output = '"hatches:hatch_closed" 2',
    recipe = {
        {'"default:wood" 1', '"default:wood" 1', '"default:wood" 1'},
        {'"default:wood" 1', '"default:wood" 1', '"default:wood" 1'},
    },
})

-- Change the hatch state
minetest.register_on_punchnode(on_hatch_punched)
-- Reset param2 for open hatches
minetest.register_on_placenode(on_hatch_placed)

-- Mesecon Stuff:
mesecon:register_on_signal_on(on_hatch_punched)
mesecon:register_on_signal_off(on_hatch_punched)


This is based off of Jeija's modification allowing mesecons to control hatches.

[Temperest]

Just a question: how can I remove then?

They can be dug in exactly 1 second, with any tool.

[cisoun]

I just noticed that. \o/
Another bug: the hatch doesn't rotate like in the first picture. It just goes up and down. Is that normal?

[Temperest]

Well with the way it is now hatches always open to the positive X axis, I'm not sure how to store the orientation properly in the node after the hatch is closed.

And if I try to dig it (and it's really hard), I can get opened hatch instead of normal (they don't stack together).

@cisoun: I may have misunderstood you at first... I had the same issue, but fixed it in my version, which you can find posted above. It requires MineTest 20120122 at minimum. I've tested my version, it fixes the issue.

@neko259: The opened hatch issue is also fixed in my version, but as I mentioned, it requires the latest version.

[neko259]

@Temperest: Can you pack the whole mod to .tar.gz or .zip and post it to omploader? I'd be grateful :)

[Temperest]

@neko259: Certainly.

[evildrummer]

Can you make a Zip version?

[Temperest]

Can you make a Zip version?

@neko259: Certainly.

Will this work on the 0.4.dev-20120122-1 version?

[Jordach]

Should do.

[RabbiBob]

Will this work on the 0.4.dev-20120122-1 version?

Does: I put it on my server this morning.

[SelfishCar]

This is great for mines....
Good work!

updated:

-- uses nodeboxes instead of raillike to allow hatch at the top of the node, opening inwards (like doors) which means you can walk over them
-- removed global minetest.register_on_punchnode and replaced with an on_punch in the node definition

http://ompldr.org/vZnkzeg is a general fix of some things.

Since the original mod has no liscence, I will assume it is to be treated as WTFPL and my changes are WTFPL as well.

all textures belong to the OP.

Fixes include the following:

Opened hatches have nodeboxes.
Opened hatches are climbable.
They're called trap doors for obvious reasons :P

[Temperest]

GloopMaster: just want to mention that cornernote has a similarly updated version here: https://github.com/cornernote/minetest-hatches :)
