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)

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

Posted: **Tue Jan 03, 2012 07:54**

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.

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.)

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

Posted: **Tue Jan 03, 2012 13:57**

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

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

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:

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.

@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

My pleasure. You've done a great job with this and I'd really like to see this go far.

Well that's kind of the problem I was trying to solve - how to avoid delays in the logic. I don't think the one second delay would allow for more complicated stuff like adders and etc.

I'll give this method a try. Actually, I had an idea - a diode made out of two blocks, the input and the output, and the output block would have two variations: normal and inverted. This seems to not need a delay, I'll write back soon with my results.

Once again, keep up the great work!

Isn't this what wireless receivers/inverters/transmitters actually do? Or what do you mean by that? Sorry if I just misunderstood you. Keep on!

jeija! go to redcrabs server! the one with port 30001!

Posted: **Tue Jan 03, 2012 17:51**

wait... I'm compiling the latest git version right now

Yeah it is pretty similar, actually, but without channels, and range limited to one block.

I'll study your wireless stuff for more inspiration.

Crafting should also be simpler for these blocks, I think - I'll try a steel + mesecon combo.

Hey Jeija, is it possible for a single node to be both a receptor and an effector?

Posted: **Tue Jan 03, 2012 18:53**

@Gatharoth: It is possible, but it will make the game crash if the signal is conducted immediately. You have to set a delay.

Posted: **Tue Jan 03, 2012 18:54**

Alright. But that's kinda the point, delay

Posted: **Tue Jan 03, 2012 18:56**

Why would you need a block to be receptor and effector at the same time? In some cases it is also possible without a delay.

Same reason as me, I guess

Making single block logic gates need that capability, or they will have to be directional.
