in the tuto:

Code: Select all

dMatrix orientation;
orientation.m_front = dVector (0.0f, 1.0f, 0.0f, 0.0f);         // this is the player up direction
orientation.m_up    = dVector (1.0f, 0.0f, 0.0f, 0.0f);         // this is the player front direction
orientation.m_right = orientation.m_front * orientation.m_up;   // this is the player sideway direction
orientation.m_posit = dVector (0.0f, 0.0f, 0.0f, 1.0f);

Why player up direction is in orientation.m_front and player front direction in the orientation.m_up ?

Code: Select all

        // No we make and make a upright capsule for the collision mesh
   dMatrix orientation;
   orientation.m_front = dVector (0.0f, 1.0f, 0.0f, 0.0f);         // this is the player up direction
   orientation.m_up    = dVector (1.0f, 0.0f, 0.0f, 0.0f);         // this is the player front direction
   orientation.m_right = orientation.m_front * orientation.m_up;   // this is the player sideway direction
   orientation.m_posit = dVector (0.0f, 0.0f, 0.0f, 1.0f);


orientation is a [4;4] matrix. You can represent that rows as:

Code: Select all

   float **orientation = {{0, 1, 0, 0},
                                       {1, 0, 0, 0},
                                       {0, 0, -1, 0},
                                       {0, 0, 0, 1}};


No matter how you call rows =) But it's a little... important... for calculations =)

Code: Select all

  float **orientation = {{0, 1, 0, 0},
                                       {1, 0, 0, 0},
                                       {0, 0, -1, 0},
                                       {0, 0, 0, 1}};

this is good, but there is a litl mistake.
It should be a pointer not a pointer to a pointer

Code: Select all

  float orientation[] = {{0, 1, 0, 0},
                         {1, 0, 0, 0},
                         {0, 0, -1, 0},
                         {0, 0, 0, 1}};

is better because it make a refrence instead of a pointer.
liek you said basically matrix is a 4x4 array of floats that make a transformation matrix.

Thank you for reply.
