[Mod] Mesecons (= redstone) [GitHub] [minetest-mod-mesecons]

[Melkor]

windows users will have to wait a little more :)

[Gatharoth]

Question, wouldn't the drawtype 'torchlike' be better suited instead of 'raillike'? Since 'torchlike' changes depending on where it is placed on a node (sides/top/bottom)? Then you would be able to change how the mesecon looks when placed on the side (side mainly because that is your "vertical" problem)

[Jeija]

I dont think it will be better. Torches are just attached to blocks, they aren't on them like redstone in minecraft.

[Gatharoth]

Okay, but would it solve your "vertical" problem though? (I am just curious since I don't know how drawtypes actually work :P)

[Jeija]

Nope, It wouldnt solve it, but signs would be interesting for that.

[neko259]

1. You could make lamps torchlike so that we would rotate them and attach to blocks.
2. Can you make signal pass throw wooden blocks? In minecraft, if I want to power a lamp (for example), I can attach it to a block and place a wire behind that block, so that my circuit would'n be seen. For now with mesecons I need to place a con just near the lamp in the open space. It's not so pretty.

neko259, +1

[Jeija]

@neko259:
1. I will make this as soon as it is possible to set the orientation of a node in the lua api. If I did that now, it would look ugly, because the lamp would rotate every time you turn it on/off (I had already planned that, see the textures for it in the textures folder)
2. Good Idea, should be possible as I got different mesecon rules now, I can do something like that... Maybe I'll make something like a sender block that makes current be transferred through one block.

[hmmm]

I dont think it will be better. Torches are just attached to blocks, they aren't on them like redstone in minecraft.

Redstone is actually a part of the block above the one they are attached too.

[hmmm]

I figured I'd report a bug! Ain't that just the grandest?
How To Shut Down Minetest Ingame!
1. Attach a blinky plant thingy with a mesecon thingy to a sticky piston thingy.
2. Place a Chest thingy infront of the sticky piston thingy and open the chest thingy.
3. Wait for the sticky piston to move the chest thingy (also works with furnace thingys and locked chest thingys!) with the chest thingy opened and enjoy! :)

The way I see it, you have 4 options (I personally prefer option 2):
1. Prevent sticky pistons (and also regular pistons) from moving those types of blocks.
2. Prevent sticky pistons (and also regular pistons) from moving those types of blocks while they're opened.
3. Make the chest/furnace close when it's moved.
4. Make the chest/furnace stay open even though it's moved.

[hmmm]

I just realized something pretty cool. When chests are moved, all their items are deleted. And with a button you can make an easy way to get rid of excess blocks like dirt and cobble without having to make a bunch of chests to fill them up with. So if you can fix the bug without doing option 1 or 4 (because 4 cant be done since it deletes the itmes) it would be really awesome and everyone will love this mod even more!

This has been known since movestones. Well, the deleting of items anyway. I don't know about the crashing, but it probably was known also.

[Jeija]

Thanks for filing the bug! I never tried that before!
I suppose it is not possible to fix the bug using option 1 or 4. I made a bugfix for option 1. I will release it when I also implemented this for movestones, sticky pistons and so on.
Cheers, Jeija

I was going to make a furnace but when i putted 2 stones like this

I made something like a pressure pad or something whatever. My point is when i putted that thing on ground the game crashed :(

You need to build Minetest from Source

[Staffs]

I did. I guess i need new version huh ?

[sfan5]

I did. I guess i need new version huh ?

Yes

[Gatharoth]

:D I have created a basic one time delay system. I'll post how-to later. I'll be working on creating a delay system that isn't one time for now.

(note: this time delay is not another mod, or a change to the mesecons, it is just a delay system using material already in the mod)

[Ushiua]

You are my god.

[Gatharoth]

Okay found a bug, sticky movestones return to regular movestones after the first use. Well, its not a bug if that was intentional.

[Jeija]

Its a bug, I may fix that. But it will take some time... I don't have that much time for mod development at the moment.

[Gatharoth]

Ah, okays. Well, that's okay. I mean come on, mod development for a game that hasn't even hit alpha/beta stage yet isn't too important.

(I said alpha stage, because to "most" gaming companies, this does not have all it's intended features and systems, where as an alpha stage game will have them, but of course, they will be buggy.)

[jordan4ibanez]

jeija do you mind if i use a heavily modified section of your code in one of my mods?

[Jeija]

Nope! Just take it if you want. The code is under the do-what-the-f***-you-want license.
But please tell me what you needed the code for... I'm just so curious ^^.

i can't tell you right now..because i am going to release a HUGE mod maybe in a week or so..but trust me you will know soon :D

[Jeija]

:D!!!

I think you should change "Object detector" crafting. Cause its SO hard to find iron :/

[neko259]

It's a bug, not a feature. We must be patient and pray^W wait for it to be fixed.

I tried to make an inverter since wireless inverters were a bit cumbersome:

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

--INVERTER: add this to your init.lua file, near the bottom somewhere

minetest.register_node("jeija:mesecon_inverter_off", {
    drawtype = "raillike",
    paramtype = "light",
    is_ground_content = true,
    tile_images = {"jeija_mesecon_inverter.png"},
    inventory_image = "jeija_mesecon_inverter.png",
    material = minetest.digprop_constanttime(0.1),
    walkable = false,
    selection_box = {
        type = "fixed",
    },
})

minetest.register_node("jeija:mesecon_inverter_on", {
    drawtype = "raillike",
    paramtype = "light",
    is_ground_content = true,
    tile_images = {"jeija_mesecon_inverter.png"},
    inventory_image = "jeija_mesecon_inverter.png",
    material = minetest.digprop_constanttime(0.1),
    walkable = false,
    selection_box = {
        type = "fixed",
    },
    dug_item='node "jeija:mesecon_inverter_off" 1',
})

--mesecon:register_on_signal_on(function(pos, node)
minetest.register_on_punchnode(function(pos, node)
    if node.name=="jeija:mesecon_inverter_on" then
        minetest.env:add_node(pos, {name="jeija:mesecon_inverter_off"})
        nodeupdate(pos)
        mesecon:receptor_off(pos)
    end
end)

mesecon:register_on_signal_off(function(pos, node)
    if node.name=="jeija:mesecon_inverter_off" then
        minetest.env:add_node(pos, {name="jeija:mesecon_inverter_on"})
        nodeupdate(pos)
        mesecon:receptor_on(pos)
    end
end)

minetest.register_on_dignode(
    function(pos, oldnode, digger)
        if oldnode.name == "jeija:mesecon_inverter_on" then
            mesecon:receptor_off(pos)
        end
    end
)

mesecon:add_receptor_node("jeija:mesecon_inverter_on")
mesecon:add_receptor_node_off("jeija:mesecon_inverter_off")

minetest.register_craft({
    output = 'node "jeija:mesecon_inverter_off" 2',
    recipe = {
        {'node "jeija:mesecon_off"'},
        {'node "default:junglegrass"'},
        {'node "jeija:mesecon_off"'},
    }
})

It's not working, though - MineTest crashes due to the two signal handlers causing conflicting messages to be sent. You can see what I mean if you put in print() statement in the function bodies: "signal on signal off signal on..."

My question is, how would I write it to create a "proper" inverter? Is it possible with the current architecture? I'm new to lua and any help would be appreciated.

[Jeija]

@Temperest: First of all, huge thanks for (trying to) contribute/ing to the mod!!!
I tried the same thing, and of course this bug also happened to me...
There are two ways to handle this problem:
1) Make a delay using an ABM or - much better the on_globalstep event. (Just create a timer and put timer=timer+dtime in the globalstep func). Create a like 1 second delay so that the server can't crash. Handle the turnoff/turnon after the 1 second has passed.
--> I use this method for the wireless inverters
2) Make the inverter directional. The output is always on the other side of the input. Unfortunately, you would have to get the orientation of the node for this (im not sure if this is possible at all) or save your own orientation in param2 i guess of the inverter node.

I hope you could understand me and I could help you. If not, feel free to ask again!
Cheers, Jeija
