This thread has taken an interesting turn. In my current project,
I've completely redone the magic system, and it allows for targetting
of spells like this. What I've done is broken the system up somewhat
and used a spell_interpreter based on the idea of command_interpreter.
Adding spells is a brease, and it is very flexible in other respects.
Actually, I did the code for general skills, and use a
skill_interpreter, but it's the same idea. The code is fairly tested,
though not completely so. Basically there is a function,
TARGET_DATA *skillFindTarget(CHAR_DATA *ch, int skillnum, char *targ);
struct target_data {
CHAR_DATA *ch;
OBJ_DATA *obj;
int direction;
int target;
};
typedef struct target_data TARGET_DATA;
The target entry is a flag of what type of target has been found. The
function is fairly well tested, though not heavily so. I'll post it
if anyone is interested, but only parts of it will be of much use,
since it interfaces fairly intimately with my skill code, which has no
stock left in it, either. The direction is simply an integer
containing NORTH, SOUTH, etc; it doesn't validate that the direction
actually has an exit (allowing for spells perhaps to make limited
doors, or something of the like).
