Something that bugs me about current damage calculation
Posted: Wed Jan 30, 2013 5:38 pm
Some of you might have noticed you do lots of 1 damage against the strong monsters, and they do lots of damage to you. It has always been like this on WoD, but veteran WoD players never noticed because old client 2.0.0b doesn't show you the damage numbers, while our new client 7.0.15.1 does. I have been reviewing this, and would like to change it. Here is how it currently works:
The CalculateAttackDamage() function determines the weapon damage based on weapon type, quality and current weapon hp. For our evaluations we will focus on a magical (exceptional, 1.2 multiplier) weapon with full hp. Lets ignore Parry and Critical Hits for now and focus on this case:
Attacker with 100 Str, 100 Tactics, and a rune blade of destruction (OLD DAMAGE before I did some changes to weapon damage (4d6+8) * 1.2 )
Defender is an Ancient Dragon (40 AR, 600 str)
Min raw damage: 14
Avg raw damage: 26
Max raw damage: 38
Min damage modified by Str and Tactics: 23
Avg damage modified by Str and Tactics: 44
Max damage modified by Str and Tactics: 64
Minimum reduction for 40 AR: 20
Average reduction for 40 AR: 30
Maximum reduction for 40 AR: 40

The problem with this formula is: It doesn't scale. so strong monsters deal lots of damage and the armor absorption becomes insignificant.
I have been exploring a new proposal and will be posting it here later today.
Code: Select all
//Hit! Figure out how much raw damage the attack did, then modify it be tactics and strength
var raw_damage := CalculateAttackDamage ();
var modified_damage := CINT ((raw_damage * (GetAttribute (attacker, ATTRIBUTEID_TACTICS) + 50 + CINT (GetAttribute (attacker, ATTRIBUTEID_STRENGTH)/5)))/100);
//Get the defender's AR rating and reduce the damage by 50-100% of that value
var defender_ar := CINT (GetDefendersAR (defender)/2);
if (defender_ar > 0)
modified_damage := modified_damage - RandomInt (defender_ar) - defender_ar - 1;
endif
//Always do at least 1 damage
if (modified_damage < 1)
modified_damage := 1;
endif
//Now check parry, if the defender has a shield
var shield := GetEquipmentByLayer (defender, LAYER_HAND2);
if (shield and IsShield (shield))
var defender_parry_skill := GetAttribute (defender, ATTRIBUTEID_PARRY);
if (RandomInt (200) < defender_parry_skill)
//Successful parry, reduce damage
modified_damage := modified_damage - shield.ar;
SendSysMessage (defender, "You parry the attack!");
//if no damage left, quit now
if (modified_damage <= 0)
return 1;
endif
endif
endif
//Players take 1/2 damage
if (defender.acctname)
modified_damage := CINT (modified_damage/2);
endif
//Do the damage
DoDamageByType (attacker, defender, modified_damage, DAMAGETYPE_PHYSICAL);
//Check for critical hit
if (GetAttribute (attacker, ATTRIBUTEID_ANATOMY))
if (RandomInt (1000) < GetAttribute (attacker, ATTRIBUTEID_ANATOMY))
SendSysMessage (attacker, "Critical hit!");
if (CheckSkill (attacker, SKILLID_ANATOMY, 80, 0) )
DoDamageByType (attacker, defender, modified_damage, DAMAGETYPE_PHYSICAL);
else
DoDamageByType (attacker, defender, CINT (modified_damage/2), DAMAGETYPE_PHYSICAL);
endif
endif
