Detailed Description

[AI] Represents a 4x4 transformation matrix, specialized for the LEGO Island engine and derived from Matrix4.

[AI]

[AI] MxMatrix is an engine-specific wrapper for 4x4 matrices, providing convenient constructors and assignment operators to interoperate with both generic Matrix4 and other MxMatrix instances. It is used for world transforms, camera transforms, and other spatial calculations within the game engine. Its underlying storage is a float 4x4 array. []

Constructor & Destructor Documentation

MxMatrix() [1/3]

MxMatrix::MxMatrix ( )

inline

[AI] Default constructor.

Initializes the matrix storage and sets identity.

[AI] Calls the base Matrix4 constructor with the address of this matrix's underlying storage (m_elements), ensuring all matrix operations operate on this data. Starts as an identity matrix.

Definition at line 22 of file mxmatrix.h.

MxMatrix() [2/3]

MxMatrix::MxMatrix ( const MxMatrix &  p_matrix )

inline

[AI] Copy constructor from another MxMatrix.

Parameters

p_matrix

Source MxMatrix to copy. [AI]

[AI] Initializes matrix storage as in the default constructor and then copies all elements from the given MxMatrix.

Definition at line 29 of file mxmatrix.h.

MxMatrix() [3/3]

MxMatrix::MxMatrix ( const Matrix4 &  p_matrix )

inline

[AI] Constructor from a generic Matrix4.

Parameters

p_matrix

Source Matrix4 to copy. [AI]

[AI] Initializes matrix storage and copies the elements from another Matrix4. Provides interoperability with generic matrix math in the engine.

Definition at line 36 of file mxmatrix.h.

Member Function Documentation

operator=() [1/2]

void MxMatrix::operator= ( const Matrix4 &  p_matrix )

inlineoverridevirtual

[AI] Assignment operator from a generic Matrix4.

[AI]

Parameters

p_matrix

Source Matrix4. [AI]

[AI] Overridden from base, copies all matrix values from a Matrix4 into this MxMatrix.

Reimplemented from Matrix4.

Definition at line 59 of file mxmatrix.h.

operator=() [2/2]

virtual void MxMatrix::operator= ( const MxMatrix &  p_matrix )

inlinevirtual

[AI] Assignment operator from another MxMatrix.

[AI]

Parameters

p_matrix

Source MxMatrix. [AI]

[AI] Copies all matrix elements from another MxMatrix.

Definition at line 66 of file mxmatrix.h.

operator[]() [1/2]

float * MxMatrix::operator[] ( int  idx )

inline

[AI] Subscript operator for access to individual rows of the matrix.

Parameters

idx	Row index (0-3). [AI]

Returns

Pointer to the first element of the row. [AI]

[AI] Allows access as m[i][j] where 'i' selects the row and 'j' the column. [AI]

Definition at line 44 of file mxmatrix.h.

operator[]() [2/2]

const float * MxMatrix::operator[] ( int  idx ) const

inline

[AI] Const version of subscript operator.

Parameters

idx	Row index (0-3). [AI]

Returns

Const pointer to the row. [AI]
