From 2870921c258d35849e7abc17ace67ea9ca355a63 Mon Sep 17 00:00:00 2001 From: H.G.Muller Date: Thu, 10 Apr 2014 14:13:38 +0200 Subject: [PATCH] Introduce separate PST for C, S and FL The light steppers now have a PST that strongly encourages their advance to the 4th/5th rank, while G, BT and DE got a completely neutral PST. The advance bonus decreases beyond the 5th rank, to discourage solo attacks. --- hachu.c | 28 +++++++++++++++++++++------- 1 files changed, 21 insertions(+), 7 deletions(-) diff --git a/hachu.c b/hachu.c index def5a0d..5900935 100644 --- a/hachu.c +++ b/hachu.c @@ -21,7 +21,7 @@ #define CHECKEXT #define LMR 4 #define LIONTRAP -#define WINGS +#define XWINGS #define KINGSAFETY #define KSHIELD #define XFORTRESS @@ -113,6 +113,11 @@ #define PST_BPPROM (3*BW*BH+BH) #define PST_BJUMPER (4*BW*BH) #define PST_ZONDIST (4*BW*BH+BH) +#define PST_ADVANCE (5*BW*BH) +#define PST_RETRACT (5*BW*BH+BH) +#define PST_WFLYER (6*BW*BH) +#define PST_BFLYER (6*BW*BH+BH) +#define PST_END (7*BW*BH) typedef unsigned int Move; @@ -614,7 +619,7 @@ int attackMaps[200*BSIZE], *attacks = attackMaps; char distance[2*BSIZE]; // distance table char promoBoard[BSIZE]; // flags to indicate promotion zones char rawFire[BSIZE+2*BWMAX]; // flags to indicate squares controlled by Fire Demons -signed char PST[5*BSIZE]; +signed char PST[7*BSIZE]; #define board (rawBoard + 6*BHMAX + 3) #define fireBoard (rawFire + BWMAX + 1) @@ -866,11 +871,14 @@ SetUp(char *array, int var) for(i=0; i 0 && p[i].pst == PST_STEPPER) p[i].pst = PST_WPPROM; // use white pre-prom bonus + if(j > 0 && p[i].pst == PST_STEPPER && p[i].value >= 100) + p[i].pst = p[i].value <= 150 ?
