This is a follow on to https://bitcointalk.org/index.php?topic=307425.0  

This is the place to discuss the programmer mode of Seuntjie's dice bot.  Also discuss the Lua language as it applies there.  

resources : http://bot.seuntjie.com/ProgrammerMode.aspx

Anything I explain here is related to the V3 B12 version of the bot.  You can get the latest version of Seuntjies Dicebot  here http://bot.seuntjie.com/botpage.aspx

To get into programmer mode click on the Settings Mode and then click on programmer



  You will see 2 panels open on the right side.  The upper panel is a reference panel of available variables, and functions.  These are only the things specific to
the bot, and not everything available.   Also you will find the open and save buttons.  A nice addition that allows you to save your programs and reload them.



  The lower panel is where your code is going to go.  It starts out prefilled with

function dobet()

end

   This is really nice since it's a major part of any program.    This is defining the function dobet.  When you start() the program this function will be called after placing each bet.  

  As time permits I will be cleaning up this post, and adding additional posts to it to explain some of the neat features that you can use with this bot.  

    That's way more involved then it should be.  Ie. there is no built in way to pause a Lua script.  There is a somewhat involved solution here. http://mushclient.com/forum/?id=4956

   But I have not tried it. 

Is there a reason you NEED to pause the script.
   No wrong answer because I've had a few times where it would have come in handy.  But for the most part I haven't needed it. 

I've only tested things on JD and PRC.  And A quirk of this, once you run out of coin to bet, the bot automatically pauses. 

Now that I'm thinking a little, Do you want to pause to invest, tip or withdraw profit? 

I've tried them all on JD, and tip /withdraw on PRC.  They all work well. 

I was planning on covering this at a later time.  I use invest on JD to take profit from the bot, and setup a second user on PRC and send them tips to take profit. 

One thing to note..   Invest/ tip/ withdraw do not update your balance.  So if your using the balance to calculate your bets, you need to remember what you took out, and adjust accordingly.   

     We can start by using the basic Martingale script from the reference site.

chance=49.5
multiplier=2
base=0.00000010
   The 3 statements before the function statement will be executed BEFORE the first bet is made.  

chance is a variable that will be used by the bot.  
multiplier and base are internal variables just used by the script.  

    After each bet is placed function dobet is called.  

   In this case, if the bet won, the variable win will be true and the script will reset the nextbet variable to the base bet.  nextbet is a variable used by the bot when placing a bet.
   If the win variable is false, then we lost the bet.  The script will execute the else path.  This will set nextbet equal to the previous bet (previousbet) times multipler.  In this case X 2.  

   The structure LUA uses for if/then/else requires an end statement.  And the function requires an end statement.

A few things I would add to the initialization section.  I would set nextbet = base so the first bet is base on my script not what is filled in the bot's panels.
Also set bethigh  Make it true if you want to go high, false if you want to bet low.  It's as easy as bethigh = false    

So my really basic script would be.

To execute this script, in the programmer mode section click on the console tab at the top.  This opens the LUA console.  The upper section is the output and the lower section is for input.  In the lower section you would type start() to start your script.  And stop() to stop it.  

   You can also use the built in simulator to see how your script will run.  Either from the built in simulator panel (click view, then simulate) ir by typing runsim (X,Y) into the console.  
X is your pretend starting balance
Y is the number of bets to place.  

Note:  Don't start your bot with a large balance.  A small error could cause you to lose everything.  Always start with a small amount just to test out all of your functions.  Of course use the simulator to flush out as much as you can.    

Why would you want to pause/rest/wait at all? The time of the bet has no influence on the result of a roll? I really don't see a point to using something like this

but since you're asking for it, you can just use sleep(milliseconds:int)

Lua is a fickle language.  Your problem is not with the sleep.  resetseed is a function.  Your treating it as a variable.  If you really want to reset the seed just code resetseed()  It doesn't take a parm.   I think there was a discussion about passing in the client seed at some point but not yet. 

also profitsincelastcycle is an undefined variable.  Lua throws up on those too.

Try this
 
   The only thing missing in the above code is what to set nextbet to when you hit your profit cycle.  Currently it will just end up being whatever it's set to. 

And I made the mistake of doing the sleep(30000) and running the simulator.  It hung for 30 seconds each time it hit that.  Basically hung up the bot.  So thats not a true sleep.  More a loop for that many seconds.   

    The problem wasn't the !win.  Lua was expecting an end for the "if win" Statement.  I was trying to leave your logic the same but missed that end statement.  So the code is


   Personally I would have handled the !win part in an else path.  But to each there own, and it's better that you understand what it's doing then I. 
 
 

  Did you cut/paste the above script?  Simulator will wait/loop.  It actually hangs the bot with the spinning circle thingy....

Are you incrementing profitsincelastcycle?  Are you checking the same variable?  You can check things out on the console.  type "print(profitsincelastcycle)"  no quotes, to see what that variable contains. 

So we left off with the basic martingale bot setting the correct first bet.   

But there is no way to stop this other then issuing the stop() command.   

This is where we can use one of the neat things about LUA.  You can set variables from the console. 

So were going to initialize a variable called stoponwin to false.  Then check this in our win path.  The variable will always be false till we change it on the console.  So our new code will not be.


so now if we wanted to stop the bot once a series is finished we can issue "stoponwin = true" at the console, and the bot will stop the next time it wins. 

 

New updated version to use a table to place the bets.  Bot will stop once the table has been run.  IE all bets in the table have lost. 

Also changed so now 2 wins or 2 loses will enable the next bet from the table on a win.   Values in the table are just for my own amusement and don't mean anything.
Also your mileage may vary....
