[Bug-gnubg] New union type in moverecord?

[Øystein O Johansen]

Hi,

As I went to my hotel room monday night, Achim showed me yet another bug
while saving and opening positions. I really think there's a dead dog
burried here which gives us problems, bugs and limitations. Half asleep I
suggest for Achim that this may be solved with a new union type in the
moverecord. Do you think this is  a good idea? I think it may solve some of
the problems we have right now.

Here's my suggestion for structure:

typedef struct _movesetposition {
    movetype mt;
    char *sz;

    /* The board _before_ any move is done, the move is not even stored */
    unsigned char auchKey[ 10 ]; /* always stored as if player 0 was on
roll */
    /* or maybe it should be int anBoard[2][25]; */

    int fPlayer;
    int anDice[ 2 ];
    int nCube;
    int fCubeOwner;
    /* evaluation of cube action */
    float aarOutput[ 2 ][ NUM_ROLLOUT_OUTPUTS ];
    float aarStdDev[ 2 ][ NUM_ROLLOUT_OUTPUTS ];
    float arDouble[ 4 ];
    evalsetup esDouble;
    /* evaluation of the moves */
    movelist ml;
    int iMove; /* index into the movelist of the move that was made */
    lucktype lt;
    float rLuck; /* ERR_VAL means unknown */
    skilltype stMove;
    skilltype stCube;
} movesetposition;

I have not done any testing or even thought about how to implement this
structure into function like saving positions and AddMoveRecord and
analysing positions. Analyse position will probably be a new menu option
with this structure. I guess it will solve some of the problems we have
today (and create some other problems ;-) )

Just think about it. Smart or not? Is the structure complete?
