I want to make a train network and have it fully intergrated with computercraft.
I did see a post somewhere on a website (might have been this one) talking about something like this but I cant find it anywhere.

What I'm looking for is for people to help point me in the right direction for writing the programs and setting it up. I want to learn how to do it as I go along. Thought I would start with a small project as my first lol ;-)

Here is a list of what I want/think my system to do:

Train Status Board - This will show if a train is at a platform and where that platform will take you
Route planning system - When a player gets into a train and presses the go button that signal will tell the "points" how to change so it goes to the right track
Train Location Board - This will be for the control room and will show what a train is doing, so for example the train from Pitsea to Basildon is heading to Basildon and the train from Southend to Grays is waiting at grays.

I'm sure there are lots more things I could add but these seem fairly massive so lets start with them.

The train station will work like a real one where players will have to wait for a train to arrive rather than calling a personal train.

I'm not sure if im going to have more than one stop per line and have the train wait for "x" time and then carry on just like real trains.

So any hints/help/ideas please.

You would have to connect your computers to redstone and monitors and wireless modems if you want this to work as I am not good with rednet I can't help you with that sorry but if you don't know how to make your computer output a redstone signal just ask me!

Ps if you found this helpful click my green "/\" in the corner

I'm not too sure, but I'm pretty sure that RailCraft is entirely redstone based meaning you will need to look here ( http://computercraft.info/wiki/index.php?title=Redstone_(API) ) and checkout how to use the redstone functionality of computers.

As for things such as displaying data about trains on platforms and such your best option is to use Rednet to transmit data around your world between computers. Info on the rednet API can be found here ( http://computercraft.info/wiki/index.php?title=Rednet_(API) ).

For displaying data on monitors you will want to take a look into the peripherals API here ( http://computercraft.info/wiki/index.php?title=Peripheral_(API) ).

There will also need to be some kind of data persistence so you will want to look here ( http://computercraft.info/wiki/index.php?title=IO_(API) ) and here ( http://computercraft.info/wiki/index.php?title=Fs_(API) ) and chapter 21 here ( http://www.lua.org/pil/21.html )

If there is anything else you need help with just ask. Feel free to post any code you have done to pastebin to get assistance with any issues quicker too.

For the display I plan to use the signal from the Railcraft Signals via bundled wire to show the redstone state.


print (redstone.getBundledInput("back"), colors.blue)
if = "true"
print ("+++++++")
else
print ("----------")

The above code is not right I know, but its just showing my thinking. On the monitor I want the train shown with ++++++++ and the track show with ——– that way I can show the progress of the train. I would like to have two types of trains with the highspeed train displayed as ******** but this might get too messy on the screen.
I dont have the advanced monitors as they are not part of techic classic.

Am I thinking in the right direction?

While x ~= "pie" dp
y = rs.getBundledInput("back")
sleep(1)
if colors.test (y, colors.lime) == true then
print ("++++++++")
sleep(1)
else
if colors.test (y, colors.lime == false then
print ("--------")
sleep(1)
end
end

I found this code here: http://www.computercraft.info/forums2/index.php?/topic/3016-video-bundled-cable-basics

Now I have no idea what the top line means, but he says it makes it repeat. The bottom bit with the prints is what I want it to do, but again I'm not sure if thats right. I hope to upload a picture of what the display will look like to help explain what I'm trying to do.

if you want your program to infinitely loop use this at the top instead of what you have


while true do

this means that the program will continue to run forever until it is either terminated by a user, errors, or the computer is shutdown or rebooted…

So if I'm understanding you correctly the 'trains' are tracked by signal boxes which can output a redstone signal when a 'train' is near by… is that right? ( sorry for the questions, I've never actually used RailCraft's advanced features before, I've always been CC or RP2… )

Yes in railcraft you have sensors that can detect when a train is between them and output redstone for things like this and also to switch tracks if the track ahead is blocked or hold the train etc.
I will have sensors on each part of my track and check the redstone state of the stations so I can track them there too.
Here is what the display of the "map" will look like:

Key:
- = Empty Track
+ = Train on Track
@ = Empty Station
* = Train at Station

Yeh ok then, given that its completely possible to do. My main concern was that you were going to have no way to know where the trains were… But you can have it show different chars to the screen too. You will definetly need to look into rednet ( since I'm assuming that track is over quite a large distance ) and the redstone API for the bundled cable control.

you could use the sensors to send redstone inputs to the commuter and have the computer display it on a monitor

Yep thats the plan, does anyone know the range of wireless redstone? I would be so much easyer if I could just use that rather than rednet.

I don't think it has one… I think… Did I say I think :P/>
I'm pretty sure using rednet on a RP2 bundled cable allows it to go further than normal too…

When I use to play tekkit Classic I tested and it worked for 250 blocks, after that I got over testing because that's wayyy more than I needed :P/>
Not sure about FTB, Tekkit Lite, though.

I'm running Tekki Classic on my server so it should be fine but to be honest I'm most likly going to use wireless redstone as it takes less time lol

Ok this is the baisc code that I've come up with, whats missing? I've not tested this yet as I'm at work (shhh dont tell the boss) but would like to sort out the code so i can test it as soon as I get home.

A monitor and a bundled cable can't be on the same side as a computer and the syntax for elseif's in lua is


if <condition> then
  -- code
elseif <condition> then
  -- code
elseif <condition> then
  -- code
end

That being said your if else statements are a little confusing in the first place with the logic behind them…

EDIT: Also thats a lot of sleeps!!!! :P/>

thats a very good point I didnt realise they were both set to back lol. As for the logic of my if's there is no real logic, I know what I want but I'm not 100% sure how to do it lol.


if colors.test (y, colors.gray) == true then 
print ("		   @-----*") 
sleep(1) 
else 
if colors.test (y, colors.gray) == false then 
print ("		   @-----@") 
sleep(1) 
end

so this bit to ME means that if the gray wire gets power it will print what I want and if its not got power it will print the other line and will keep checking every second to see if it has a signal. This is so that the map is live. I then just copy and repeated this. The one thing I may have a problem with is getting it to display on the lines/rows I want it to like it does in the picture above.

ok so before I suggest some improved logic… the colours will be the location of the train on the map? or the type of train it is?
to set the cursor location for printing you can use

term.setCursorPos( x, y )

where x and y are the location on the screen you wish to set it to.

also side note here that code will take a minimum of FAR more than 1 second…

EDIT: oh another thing I just noticed, it will never print to the monitor… you have to redirect the computer to the monitor if you wish to use the print function to print to the monitor


-- after you have wrapped the monitor and want to print to it
term.redirect( monitor )

-- all your program code here

-- at the very end of the program ( or when you want to print on the computer again )
term.restore()

Print actually automatically goes to the next line for you… but this is a basic form of how you would do it ( I'm following the same pattern you have for your strings to print, these may need to change later so one string doesn't write over another )…


while true do -- loop forever, unless of error or termination by the user
  term.clear() -- clear the screen for printing
  term.setCursorPos(1,1) -- put the cursor in the top left
  if colors.test( y, colours.magenta ) then
	print("@----@----@----@----*")
  else
	print("@----@----@----@----*")
  end

  if colors.test( y, colors.pink ) then
	print("		 +			   /")
  else
	print("		 \\			   /") -- this needs \\ here because \ is whats known as an escape character
  end

  -- etc, etc, etc

  sleep( 1 ) -- sleep for a second at the VERY END of drawing the whole screen...
end

Ok I've now managed to confuse myself by trying to work out a question lol.
Basicly If i set the cursor to 1,1 for the first line can I just add the cursor set code but have 1,2 on the if bits so they display on the second line and format right?

Also someone ^^^^ sugested I use FTB for my server so that means I will have Advanced Colour scrrens, where can I find out how to make my code even more complicated with color? lol

I would explain more but I need to wake up in 5 hours so really need to go to bed :/

Good luck, I hope this all makes sense, I should be able to answer any questions you have in the morning…

What does this bit of code do? Whatever it is does not work (I guess I need to edit it with something?)

It checks for a peripheral of a specific kind. The kind should be a string matching the type of the peripheral.

As ChunLing stated this will check for a given peripheral so that you don't have to specify the side everytime in code ( it makes it more dynamic that way )
so in the code i called it this way


local monitorSide = findPeripheral( "monitor" )

Ahh that's your problem… Line 19 you changed it from how I had it to a static side instead if searching for a side. Either change it to monitorSide or "right"…

Lol maybe

Right its all working now, thanks….but
I want it bigger and in the middle, I've done this and it makes the first line go in the middle but the next one doesn't and when it does the color checks they have been told to go to 1,1 etc.
How do I get it all relative? Do I have to work out the middle and set the positions that way?

term.clear()
term.setCursorPos( sizeX / 2 - #msg / 2, sizeY / 2 )

I cant remember what the text size code is aswell and the wiki is crap, I found it yesterday but now i cant find it

I tried using

But that gives me the attempt to call nil error :(/>

Lol maybe

Right its all working now, thanks….but
I want it bigger and in the middle, I've done this and it makes the first line go in the middle but the next one doesn't and when it does the color checks they have been told to go to 1,1 etc.
How do I get it all relative? Do I have to work out the middle and set the positions that way?

I did this


local function drawScreen()
term.clear()
term.setCursorPos(5,3)
monitor.setTextScale(3)
-- first we draw the default path on the screen
print("----@----")
term.setCursorPos(5,4)
print("----@----")

I'm slowly learning how to read code lol, term. is for the terminal but the term API doesn't have scale listed so I changed it to what you had wrapped the monitor as.

Now to make it color lol

haha :)/> yeh term doesn't have it but the wrapped monitor does… :)/>

btw the default path you can actually just have it in a print like this


*make it centre*
write( *the whole top row in quotes* )
*make it centre*
write( *the whole second row in quotes* )
*make it centre*
write( *the whole third row in quotes* )
etc, etc, etc

its just for the little bits that we need to have it separate so that it only draws over the part its meant to… :)/>

I have no idea at the moment lol
It could be done using the signals and redstone again. The signals have 5 states, green, yellow, red, flashing yellow and flashing red. Each state changes depending on what direction the cart is traveling and the flashing ones mean an error with the track.
Green - Line clear
Yellow - Cart traveling away from you
Red - Red Cart traveling towards you.

So the board could read "Pitsea Express - On Time" if the lights are yellow and
Approching for when its red.

It helps if you know Railcraft, but its doable..with some coding help at silly aclock in the morning im sure lol

If your trains took exactly the same amount of time to arrive at the station each and every time, you could hard code in the times. The best bet for this would be from the last point on the track you can detect the train, time them from that point (signal…or whatever you have that could detect them) and start the timer as soon as the train passes over that point.

I had a look and his system is nie but not a fan of the email system and it doesnt use RC.
My system is going to be simple, just using signal box's to send restone signals back to computers.

One quick question, does the computer have to touch the monitor or can I run a cable to it?

Is there a timer program in cc or would I have to just count in my head/ with fingers and toes?

Sadly the computer has to touch the monitor.


* detected rs signal *
local startTime = os.clock()

*wait to detect second signal*
print( os.clock() - startTime )

ok so how does this script work?
From what I "know" you have said that the term "startTime" will return the value of "os.clock" that will be the CPU time according to the wiki. then you have said to print the cpu clock - cpu clock?
How does it detect the rs signal? Would i use the bundled cable code again? I will be reciving the signal via a bundled cable.

yeh os.clock is mc time…

whatever color the bundled cable is at the points between where you want to measure…

so it would be lime this


local function waitFor( c )
  while not colors.test( rs.getBundledInput( "back" ), c ) do
	sleep(0)
  end
end

waitFor( colors.red )
local startTime = os.clock()

waitFor( colors.lime )
local endTime = os.clock()

print( ( startTime - endTime ) )

you will want to change the colours appropriately

You might want to do a little formatting to get that number into seconds / minutes… but thats the base code…

Well that kinda worked, gave me a result of -26.15, so now I have a major problem, I've created the worlds crappist time machine! lol

On a better note I have managed to get my departures screen to work well, it shows when a train is approching, at the station and leaving.

Now just designing how the station is going to look with all this tech in it.

Anyone got any tips on how I can get my control room display to look abit nicer?

Well just add sensors everywhere and have some kind of mapping software that maps out the players depending on the sensors they are tripping…

Use openCCSensors… ccSensors is buggy as hell and only works in 1.2.5 … only reason remiX and I did the tutorial is because of a HUGE influx of people coming on asking for help with it and virtually no one knows it…

I'm going to be formatting the display code later and wated to know if there was an easy way to work out what size text will fit what size screen and also how to make sure all my text is going to be where I want it. Will it just be a case of trial and error?
I will have to have 18 lines of text displayed and the board will have 3 rows of info and can be as wide as it needs to be i guess, whats the max size of a monitor?

as far as I'm aware its pretty much trial and error when using text scale… you can use term.getSize() which returns width and height… altho I haven't checked what it returns when scaling the text…

Computers don't generally creat tons of lag. The only time you're going to get noticable lag is when you are either refreshing a screen ridiculously fast, or when you are spamming rednet. From what I understand, rednet was a problem in earlier versions of CC.

I dont use rednet so thats not a problem, I update the screen everytime a train moves to a new part of the track but I dont think that should make too much problem.

Ok so my station design is getting a little out of hand I want 2 computers per platform with the station having 4 platforms, then I want a big departures board showing the status of all 4 platforms (each platform has 2 sides so thats 8 signals), thats just to track the location of each train in the station, then I want my tracking software in the main control room that tracks the status of every track outside of the station so I can track cart locations. I would also like a board in the main control room that showed the status of other stations (so ones not including the one its in)

Is it me or will I run out of room for all thes bundled cables and wireless redstone bits, should I bite the bullet and go rednet? I really dont want to as I just(with lots of help) about know how to use my current setup lol.

( Sorry for my bad english, but I try to explain what I have in mind: )

If you decide to do a new setup, maybe think about some string-operation?!? install a sensor for each track/station etc. and get the status via modem in your terminal.
Then - if you like to update your display - just check each status and depending on the findings set up some strings, which then can be print on the display:

[first setup]
string1 = "—–"
string2 = "X"
string3 = "@"
string4 = …………..

[check status in a loop for all sensors]
if status = on then
string_out_1 = string1
else
string_out_1 = string2
end

print (string_out_1..string_out_2..string_out_3)

hope you get the idea, its just a rough scheme ;)/> ???
