Modeling Individual Decisions - Behavioral Mathematics for Game AI - page 368

Notice that, because our formulas can generate values that are less than 0, we
must clamp the minimum on both values to 0. We can't do negative damage, and we
can't have less than a 0% chance of hitting our target. Other than that, the formulas
for calculating the values are familiar as code-ese translations of their mathematical
versions we expressed above.
We define an array of CWeapon objects in the CWeaponCollection as follows:
#define MAX_WEAPONS 4
CWeapon mWeapons[MAX_WEAPONS]; // Array of all weapons
CWeaponCollection also has accessors for looking up information about any
of the members of its array by index. These accessors simply pass the request on to
the matching accessor of the referenced object.
The important function that CWeaponCollection performs, however, is to ini-
tialize the array with the four weapons we have defined in our game. We do this
through the function InitOneWeapon() .
void CWeaponCollection::InitOneWeapon( WEAPON_TYPE Type,
char* Name,
USHORT MaxRange,
USHORT BaseDamage,
double DmgDecayExp,
USHORT DmgDecayDiv,
USHORT DmgDecayShift,
double BaseAccuracy,
double AccDecayExp,
USHORT AccDecayDiv,
USHORT AccDecayShift )
{
mWeapons[Type].SetMaxRange( MaxRange );
mWeapons[Type].SetBaseDamage( BaseDamage );
mWeapons[Type].SetDmgDecayExp( DmgDecayExp );
mWeapons[Type].SetDamageDecayDiv( DmgDecayDiv );
mWeapons[Type].SetDamageDecayShift( DmgDecayShift );
mWeapons[Type].SetBaseAccuracy( BaseAccuracy );
mWeapons[Type].SetAccDecayExp( AccDecayExp );
