Common Types
This page lists types commonly used in WoW, but not specific to a file format.
foreign_key
A reference into a DBC or DB2 database file. E.g.
foreign_keyⁱ<uint16_t, &LiquidTypeRec::m_spellID> liquid_spell_id; ^ type of reference ^ table referenced ^ variable referenced
stringref
A reference into the string block of a DBC or DB2 database file. See DBC#String_Block.
using stringref = uint32_t;
langstringref
A field for localized strings, consisting of an array of stringrefs followed by a field of flags. The amount of language entries depends on the version, with Cataclysm dropping all but the client's language. See Localization for details.
struct langstringref { //! \todo verify that pre-wotlk locales hadn't changed #if < stringref enUS; // also enGB stringref koKR; stringref frFR; stringref deDE; stringref enCN; // also zhCN stringref enTW; // also zhTW stringref esES; stringref esMX; #if ≥ stringref ruRU; stringref unknown_9; stringref ptPT; // also ptBR stringref itIT; stringref unknown_12; stringref unknown_13; stringref unknown_14; stringref unknown_15; #endif uint32_t flags; #else stringref client_locale; #endif };
C2Vector
A two component float vector.
struct C2Vector { float x; float y; };
C3Vector
A three component float vector.
struct C3Vector { float x; float y; float z; };
C4Vector
A four component float vector.
struct C4Vector { float x; float y; float z; float w; };
C33Matrix
A three by three matrix.
struct C33Matrix // todo: row or column? { C3Vectorⁱ columns[3]; };
C44Matrix
A four by four matrix.
struct C44Matrix // todo: row or column? { C4Vectorⁱ columns[4]; };
C4Plane
A 3D plane defined by four floats.
struct C4Plane // todo: verify { C3Vectorⁱ normal; float distance; };
Those 4 floats are a, b, c, d variables from General form of the equation of a plane
C4Quaternion
A quaternion.
struct C4Quaternion { float x; float y; float z; float w; // Unlike Quaternions elsewhere, the scalar part ('w') is the last element in the struct instead of the first };
CRange
A one dimensional range defined by the bounds.
struct Range { float min; float max; };
CAaBox
An axis aligned box described by the minimum and maximum point.
struct CAaBox { C3Vectorⁱ min; C3Vectorⁱ max; };
CAaSphere
An axis aligned sphere described by position and radius.
struct CAaSphere { C3Vectorⁱ position; float radius; };
CArgb
A color given in values of red, green, blue and alpha. Either
using CArgb = uint32_t;
or
struct CArgb // todo: verify, add CRgba, ..? { unsigned char r; unsigned char g; unsigned char b; unsigned char a; };
CImVector
A color given in values of blue, green, red and alpha
struct CImVector { unsigned char b; unsigned char g; unsigned char r; unsigned char a; };
C3sVector
A three component vector of shorts.
struct C3sVector { int16_t x; int16_t y; int16_t z; };
fixed_point
A fixed point real number, opposed to a floating point.
template<typename Base, size_t integer_bits, size_t decimal_bits> struct fixed_point { Base decimal : decimal_bits; Base integer : integer_bits; Base sign : 1; float to_float() const { return (sign ? -1.0f : 1.0f) * (integer + decimal / float (1 << decimal_bits)); } };
fixed16
A fixed point number without integer part.
using fixed16 = short; // divide by 0x7fff to get float value
or semantically (0 is not a valid bit size in bitfields) equivalent to
using fixed16 = fixed_pointⁱ<uint16_t, 0, 15>;
