Setting up the *.ohf File for DLL Use
This part of the series will concentrate on how we will pass decisions from the dll to the autoplayer. It’s simple, the *.ohf file contains the instructions for the autoplayer and will call the variable from the dll which contains the decision.
Setting up the DLL
First we need to introduce a decision, variable. You can download the files used for this part. I will go through the changes I made:
- Added includes for preflop, flop, turn, river code
- Added include for global vars
- Added decision variable and call in "process_query"
- Added code to set the decision variable in "process_state"
Changes to OH-DLL.cpp
Include Section
The include section looks like this now:
#define WHUSER_EXPORTS #include "OH-DLL.h" #include <windows.h> #include <bitset> using namespace std; #include "OH-globalvars.h" #include "OH-general.h" #include "preflop.h" #include "flop.h" #include "turn.h" #include "river.h"
Changes to process_querry / process_state
double process_query(const char* pquery) {
if(pquery==NULL) return 0;
//example
if(strcmp(pquery,"dll$decision")==0)
return decision;
return 0;
}
double process_state(holdem_state* pstate) {
if(pstate!=NULL) m_holdem_state[ (++m_ndx)&0xff ] = *pstate;
//resetting decision
decision = 0;
//updating vars
int_oh_symbols();
//calculating decision if it’s my turn
if(ismyturn){
switch(betround){
case 1:
decision = preflop();
break;
case 2:
decision = flop();
break;
case 3:
decision = turn();
break;
case 4:
decision = river();
break;
default:
break;
}
}
return 0;
}
You can already see from the comments what is happening here, each time a new state is scraped:
- "int_oh_symbols" updates the values of our defined oh-symbol variables.
- the "decision" variable is reset to "0".
- when it is our turn (buttons visible) we call the code depending on the current betround to set the "decision" variable.
Preflop, flop, turn, river includes
Until now they do not contain any code, they simply contain a function each which returns 0, e.g:
double preflop() {
/* preflop code */
return 0;
}
My next part of this series will be concentrating on coding a basic preflop for deep stack NL.
Include for global vars
///////////////////////////////////////////////////////////////////////////////////////////////////////////////////// //OH DLL VARS ///////////////////////////////////////////////////////////////////////////////////////////////////////////////////// //CONSECUTIVE STATES holdem_state m_holdem_state[256]; unsigned char m_ndx; //VERSUS LIST AND PRWIN phl1k_t m_phl1k; pp13 prw1326; //SYMBOLS VAR pfgws_t m_pget_winholdem_symbol; ///////////////////////////////////////////////////////////////////////////////////////////////////////////////////// //OWN VARS ///////////////////////////////////////////////////////////////////////////////////////////////////////////////////// //GENERAL VARS int ismyturn; int betround; double decision; //SUIT VARS int srankhiplayer; int srankbits; int flushrank;
I decided it’s best to keep the vars in one include, as you will have tons of code later and it will be much more convenient to organise it in include files. My former NL micro stakes script contained about 50k lines. As you can see I added two new variables, "ismyturn" and "betround".
Setting up the *.ohf file
This is how a *.ohf file might look for this dll, ofourse I am always open to suggestions if someone else has any to improve it.
Code in ##f$betsize##
- If our "decision" is 1 bblind or more we will enter the closest amount in bblinds.
Code in ##f$call##
- If for some reason we can’t enter the betsize and your "decision" is not 0 we call.
- If the balance is smaller than 3 bblind we call. This is a failsafe, in case for some reason we will have put almost all money allin except a very small amout which can be left, if you are not very careful. Possible reasons are a problem with the exact dezimal representation of numbers or improper handling of the slider-bar.
- If we don’t need to call anything we obviously check.
