[Mod] Digilines [minetest-mod-digilines]

[Jeija]

The digilines mod existed for some time already, even without getting noticed by many people. Now I decided to release it aside from mesecons to spread it.
In fact it's not only and addition to mesecons, but can also be used by other mods, use your creativity!
Presenting: The minetest counterpart for real-life digital bus systems like i2c, SPI, RS232, USB, OneWire, ...

So, what is it good for?

Use case 1: Link luacontrollers together; Use them as port expanders or even create a dynamic network. For this use case, I can recommand The Tic-Tac-Toe Machine on the Mesecons Lab by Uberi which demonstrates this feature impressively.

Data is always consists of a channel and a message to be sent. See the luacontroller documentation for more information.


Use case 2: Hook up external Hardware to a luacontroller. At the moment a Real Time Clock (RTC) that gives you the current timeofday, a light sensor and an LCD display are included.
For the display, just send your text on the channel you selected when right-clicking it, in order to retrieve time or light data, send a "GET" to RTC or light sensor on the selected channel.

For developers: See the RTC, Light Sensor and LCD code to develop your own things using the digilines features.

Dependencies: none, but currently not usable without luacontrollers (=mesecons); no crafting recipes, so creative is also recommended

So people could create extra hardware to interface with diglines?

[Jeija]

Yes, that would be awesome. You could make inputs (temperature, moisture, pressure sensor, keyboard input or Node detector), computing stuff (memory chips, or sth. like the luacontroller) or effectors (displays, lights, node placer).

Just think of what bus systems are used for in real life, they're just everywhere!

[webdesigner97]

Why do you make so awesome mods, Jeija?? O.o

[Traxie21]

Are you asking Jeija to stop making awesome mods? :L

[webdesigner97]

of course no! :D

There should be a type of ore that after you mine it, you can craft it into digiline parts, like mese with mesecons. I will try to do that, but I need to wait until I can use a computer that minetest works on.

[jordan4ibanez]

Add this to mesecons extensions on the site yes?

[prestidigitator]

Wow. That LCD display is insane! I tried to do the same sort of texture combining to tile a background color for "dyed" stone with an overlaid texture, but I guess my texture names were WAY to long for even a few tiles (crashed the server when the final texture string was apparently long enough it didn't want to send it to the client). Seems like we might need some kind of API method for at least simple text-based dynamic texture creation....

[Sokomine]

Very intresting! That makes making circuits far more intresting since we don't have to do the low level stuff anymore. Thanks for the mod!

For digilines crafting recipes, maybe you could use floatstone, since I think floatlands have been recently merged.

Is there really a need for crafting recipes? I mean, I would never use something like digilines in survival mode, the gameplay in survival is just totally different.
You likely only need these things to make giant structures (for most use cases at least) and you wouldn't build them in survival mode anway IMO.

There is always a need for crafting recipes. People like me find a lot of joy making things like this in survival mode because it has a feeling of accomplishment and it definately gives you an additional thing to add to your survival house. So please, create a crafting recipe.

[12Me21]

You can just add some yourself, you know.

[Likwid H-Craft]

Hey, Jeija do you think it possible you and I can management a way make GLaDOS with how good you at making all, this power and, wiring stuff...

Well I was really thinking make GLaDOS a mob but, I don't think it possible make her that big and everything...

Edit:Oh yours wiring mods, reminds me of Gmod Wire Mod take a look at it you may possible make, Wire mod possible on Minetest.

[oxenfreedan]

So I didn't really get it.... So can someone explain what this mod really does.

Form my understanding it allows you do something in real life...

I think the version of flolands that was merged uses regular dirt and stone.

[jojoa1997]

What are float lands now in default? Where are they?

Not really, thtat video would have also been possible without digilines. You know, mesecons is some kind of low level electronic stuff that all sorts of modern electronic devices use. But often, different parts of devices need to communicate, like your Computer with a USB stick or a washing machine's control panel with the interior. It would be too complicated to make this kind of communication on a low level base, instead, you create some bus wire like i2c, USB or digilines that makes communication easier and on a high level.See the TicTacToe-Machine on http://uberi.mesecons.net for an example usage. If you still don't understand what I'm talking about, this mod was not made for you, just ignore it.

this whole thing is just confusing to me

I agree, I have been experimenting with mesecons in a Survival Mode world, and I'm working on creating & balancing digilines recipes. I will probably submit to the github when I'm done. Thanks Jeija for making such a cool mod!

[clarksallador]

how do you use this ?

[Jeija]

clarksallador, if you don't get what this is then nevermind, this mod was not made for you.
If you have trouble with some specific thing, tell me what exactly what you want to know.

Jeija, I have created recipes for digiline and digiline_lcd , and have submitted a pull request on the digiline Github. Please review when you get the chance.

If anyone wants to add these recipes right now, replace your minetest-mod-digilines folder with git clone git://github.com/lordcirth/minetest-mod-digilines.git .

Concerning what the digilines could be made out of, it could be a type of crystal similar to mese, but stronger than it and diamond. It could be called CONS and have the letters of that name on its blocks. Obviously, it could be a very rare find (it too could be of extraterrestrial origin just like mese is.)

I think that digilines should be crafted out of insulated mesecons, just as our data wires are bundles of insulated wire. It makes the most sense and avoids adding more wacky ores to the game.

How does the get statement work for a light sensor, do I need to use it with a variable

I was hoping I could use it by testing if it was on
"e.g. if (port.a == 1) then
do this
endif"

would it be possible to provide an example?

any help is appreciated

[Jeija]

This is some untested sample code for the light sensor:

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

digiline_send("channel_of_lightsensor", "GET")

if (event.type == "digiline" and event.channel == "channel_of_lightsensor") then
  lightvalue = event.msg
end


What happens?
First, you need to request data from the lightsensor by sending the string "GET" on it's digiline channel. The light sensor will then answer with the light value on the same channel. This answer throws an interrupt of type "digiline", the light value is contained in event.msg.
The channel of the Light Sensor can be set by right-clicking on it.
By the way, the RTC works in the same way. I hope the example works for you, tell me if I made a mistake.

If you just want a light there / light missing answer you could use the solar panel from mesecons instead with

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

if pin.a == true then
  -- do something
end


[pheonixfire]

Do I just put "port.a =" in front of the digiline_send to specify which port
is used to send the request?

any help is appreciated
