This idea seems pretty good to me

While there are addons that add cards like OpenSecurity they only hold the information to be later presented to a scanner. This is insufficient for application where protection of the stored data is required as with payment cards for example, where one can not guarantee the software running on the scanner is legitimate. So... in order to avoid getting your card details stolen, duplicated and used without your consent we need some zero-knowlede proof of our secret. This could potentially be done in the base game with tablets, datacard and a wireless, but I think a dedicated card that could be crafted cheeply with just CPU, EEPROM and some miniature Datacard would serve this purpose better.

So what should this smart card do? It should contain a simgle function to encrypt whatever challange string is passed to it by the reader with encryption key stored on the card. That's it. The reader can then verify if the challange string was correctly encrypted either by decrypting it themselves or relaying it to the card issuer.

It appears that robots deal greatly reduced damage with held weapons and `swing()` since Minecraft's "Combat Update" introducing melee cooldown mechanic.
Tested with `OpenComputers-MC1.8.9-1.7.0.175.jar` and `OpenComputers-MC1.9.4-1.7.0.132.jar` as only mods with respective MC version.

Reproduction

• Set up Minecraft 1.8.9 and Minecraft 1.9.4 instances with Forge and OpenComputers.
• Create new creative world with default difficulty (Normal, `1.5` would be local difficulty).
• Have Creatix wield wooden sword and count how many hits it takes to kill zombie.

Setup:

In 1.8.9, it takes 5 hits:

In 1.9.4, it takes whopping 27:

First, I want to thanks the creator of this mod and all his contributors, because this mod is just amazing.

As a developper, I was impressed by your work, OpenComputers is very realistic, it's a real computer simulation.

I love when you doing some IOs and you can hear the disk noise, tons of little features like this <3 

I'm planning for learning scala, I think I will read your code soon to study minecraft modding ;-)

Anyway, this is not the goal of this thread.

It would be nice to add more micro-controllers features like lcd screens, buzzers,  RF emitters/receivers

Micro-Components

This features introduce a new concept : The micro-components.

There are designed to be used with micro-controllers.

The difference with normal components is the size, it's not a block, but more like a keyboard.

In fact, keyboards can be considered like a micro-component and be compatible with micro-controllers.

LCD screens

A lcd 32*32 (or smaller) screen ?

- This LCD screen would be used by micro-controllers, very useful to debug them.

- The LCD screen would be flat, like keyboards.

- [T1]: Black and white screen

- [T2]: Can configure background and foreground colors using dyes (in a crafting table)

- [T3]: Can use all colors

Buzzers

It's just the normal buzzer you can found in a computer case, but in an external component.

- The buzzer would be used by micro-controllers. (e.g.: debug, alerts, alarms)

- The buzzer would be flat too

RF emitters / RF receivers

Used for  communication between micro-controllers

- Short range

- Based on frequences

- Flat with an antenna ;-)

Micro-components are flat

Like I said, all micro-components are rendered flat like OpenComputers keyboard, It's the way to differentiate normal components from micro components.

Combining 2 micro-controllers will result to have something comparable to a slab (in term of size), you cannot combine more than 2 micro-components in the same block.

I connect server to Remote Terminal but Remote Terminal dont show anything

Help me please
(OC 1.7.7)

1. laptops - it should be a simple but expensive device like a tablet, but it can be installed on a block without a dock (spoiler) and used both in hand and on blocks, it can be moved without turning off, it will retain its state even after re-entering the world (which, for a strange reason, the tablet does not know how)
2. dock station - will allow you to install the tablet on the unit and allow it to connect to external components
3. different levels of eeprom - let the standard eeprom be the second level and there will also be an eeprom 2 times less and 2 times more
4. the import map is like in open computers 2 - with it you can upload data to the computer and the program on openOS will put it in a file
5. level 4 components (emerald) - they should be very, very expensive and be very good, level 4 monitors will be able to stretch the picture to the full screen while the resolutions will remain too long to stretch the characters themselves
6. security settings - with the assembler, it should be possible whether the device can be disassembled, whether it will be possible to change the eeprom through the workbench, whether the tablet disk will be determined by the computer, etc.
7. temperature - the components should have the property of overheating they should have a temperature and they are different components in different ways to warm up and overheat at different temperatures (for example, an Internet card will get very warm and for a quick and buzy download you will have to put several Internet cards and use them very often)
8. rawCard - will have several buffers in (depending on the level, their number and dimension will change) and which can be placed raw music data (song with words) and it will be possible to turn on and start sounds

fix

• animation of ventelators on computers
• the tablet should save the states
• of the server disk drive should have the media method
• the built-in disk drive should be defined as a component in both computers and tablets and robots, and should contain at least the isEmpty and media method, if possible, the eject
• computer beep should block not until the end of the beep, but only if another
• screen is already writing, should NOT respond to the redstone signal (this greatly hinders)

I don't know if it's possible

1. upload an ISO file from  your computer  into the lua BIOS

2.boot from the ISO file

if that's possible , THANKS :)

Edit: I realize this is probably better posted as an issue to GitHub so this can be disregarded.

• Optimized GPU rendering code, providing up to 2x better performance (in terms of frame rendering time),
• LuaJ and JNLua bugfixes and updates,
• Native Lua performance improvements,
• Lua 5.4 support! (currently on lua-5.4.0-beta)

This is the feedback thread for this fork, as input is sought before merging the changes back into OpenComputers due to their potentially invasive nature (for bug reports, please use the issue tracker).

When I use the robot Creatix I input these commands:

/home # lua

lua> r = require("robot")

lua> r.forward()

and it moves one block. But The screen doesn't refresh, I couldn't see such as "lua>" on it and I couldn't do anything else.

But if I input like this...

/home # lua

lua> r = require("robot")

lua> r.swing()

true         "block"

lua> r.forward()

true

lua> r.swing()

true         "block"

lua> r.forward()

true

lua> swing()

false         "air"

lua> r.forward()

And it will not work.

I could say, when I put blocks in front of him and it breaks the blocks at first, it could move, or it will strike(if all of blocks are already broken, it will also strike like the second example).

The situation on my computer is not like this. It works perfect and nothing wrong.

PS: if I input like this:

lua> while true do r.forward() end

it will just move 1 step. And stay there.

if I create a script with:

r = require("robot")

while true do

    r.forward()

end

and run it. the robot will still move 1 step, and stay there. The screen has also no reaction.

PS II: PLZ repair it, this mod excellent and I don't wanna play without it(and CC is not available for 1.12.2), so PLZ repair it. It so interesting.

Thank you for the development of this mod, again.

The first suggestion, is remove the abstraction on network communication in the first place. Allow this to be configured in the mod preferences file, but have it enabled by default. By default, there is no “hardware addresses”. A cable is just that, a cable. The only API by the mod is “broadcast and receive”. In the OS provided by the game by default could still have the same API as now. The different is it’d behave like broadcast, with packets being what are broadcasted. The new network card API (excluding any OS-level abstraction would look like this: 

- card:up()

- card:down()

- card:listen()

- card:transmit(raw)

Already, we now have a lot of extra things. It encourages crafting an encryption card (or whatever it’s called) because users can now snoop and preform MITM attacks on these packets, since there is no game mechanic (provides by the mod itself) preventing posing as somebody else. That also means you can simulate multiple networks cards in software while crafting only one. 

Second, something that kinda complements the idea of the first suggestion. Cable bandwidth limits. Just like normal cables, there is a limit to the amount of data we can cram into a single cable. Since the last suggestion removed the magic of hardware addresses, we actually need to listen to packets on the cable. We can only process so many packets so often. Now, us developers have an actual NEED to work on more complex softwares. We need to design things like intelligent multiplexing algorithms and routing softwares to efficiently receive, decode, process, bundle, re-encode, and transmit packets. 

There will also now be tiered network cards, that change things like the maximum number of packets a second the card can receive and transmit. It could also limit what kinds of cables the system can connect to. For example, you might need a tier four to connect to fibreglass. 

Keeping on the same note, Radio Frequencies. Just like cables, we can only send so much data through the air at once. One way we allow for more people talking wirelessly, besides just having everybody wait their turn in a long que to talk, is Frequency Multiplexing (FM). This also adds a new unique challenge, but powerful tool, to busy areas. You can allow a lot of people to talk at once using multiple frequencies, but you need to develop systems to send data to users on the right frequency to have them actually receive it.

Radio Frequencies would have different reasons to use it. Higher frequencies can transmit farther, but they use more power and they can be affected by things like weather (If I understand correctly some RF wavelengths can experience interference due to the size of the droplets). Lower frequencies would use less energy, but have lower range, but less susceptible to interference from things like weather (however, if memory serves right, lower frequencies are more noisy; translates in-game to possibly more failed packets and corruption). 

In the game, tiered wireless cards have been added. The higher tiers have the capability for wider bandwidth (meaning the range of RFs the card can use), multiple antennas (allowing use of multiple frequencies at once), and higher bandwidth (packets/second it can receive and transmit). To craft these, one good way could be like how you setup server racks. You can open a GUI where there are slots. You need better processor for higher throughput (packets/second) and higher memory for higher throughout volume capacity.

All my suggestion make the game more difficult, sure. That’s why I use it over ComputerCraft. I like having my computers be complex and expensive, they should be! They’re freaking computers.

This adds the ability to design a lot of new things, and new challenges. However, they won’t really effect new players. On your small one or Teo computer network running the default OS, everything will work perfectly fine. Only large-scale complex systems have these issues.

Mod Version: 1.5.22.6

Hey,

I was wondering if there is any chance to see a high precision computer.pull function in OpenComputers, allowing to have timeouts below one tick (I believe the currently used computer.uptime only returns time with .05 s precision).

With that in hand, non-blocking sleeps and timers for small time intervals should be realizable. I was trying to implement this in openOS by adding a computer.pull function using os.clock instead of computer.uptime and changing some other libs accordingly, but it didn't work out.

So I'm asking if there is any reason against adding a higher precision version of computer.pull to "machine"?

Thanks:)
