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_key<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  < Cata
  stringref enUS; // also enGB
  stringref koKR;
  stringref frFR;
  stringref deDE;
  stringref enCN; // also zhCN
  stringref enTW; // also zhTW
  stringref esES;
  stringref esMX;
#if ≥ Wrath 
  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;
};

C3iVector

A three component int vector.

struct C3iVector
{
  int x;
  int y;
  int z;
};

C4Vector

A four component float vector.

struct C4Vector
{
  float x;
  float y;
  float z;
  float w;
};

C4iVector

A four component int vector.

 struct C4iVector
 {
   int x;
   int y;
   int z;
   int w;
 };

C33Matrix

A three by three matrix.

struct C33Matrix // todo: row or column?
{
  C3Vector columns[3];
};

C44Matrix

A four by four matrix.

struct C44Matrix // todo: row or column?
{
  C4Vector columns[4];
};

C4Plane

A 3D plane defined by four floats.

struct C4Plane // todo: verify
{
  C3Vector 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
{
  C3Vector min;
  C3Vector max;
};

CAaSphere

An axis aligned sphere described by position and radius.

struct CAaSphere
{
  C3Vector 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;
};

C3Segment

 struct C3Segment
 {
   C3Vector start;
   C3Vector end;
 };

CFacet

 struct CFacet
 {
   C4Plane plane;
   C3Vector vertices[3];
 };

C3Ray

A ray defined by an origin and direction.

 struct C3Ray
 {
   C3Vector origin;
   C3Vector dir;
 };

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_point<uint16_t, 0, 15>;
