.SH DESCRIPTION
These functions are used to deal with details of
.I glendy
(also known as cat trap)
and make writing clients easier.
.I initlevel
sets up the map with glenda always on middle
and amount of walls based on
.I difficulity
variable,
.TP 10
.B DEasy
10 ≤ x ≤ 15
.TP 10
.B DMed
5 ≤ x ≤ 10
.TP 10
.B Dhard
1 ≤ x ≤ 5
.TP 10
.B DImp
x = 0
.PP
where
.B x
is amount of walls, chosen randomly.
.PP
.I movedir
function returns the point
.I p
after being moved in
.I dir
direction,
or
.B {-1, -1}
in case of invalid input.
.I pointdir
is the reverse of
.I movedir
function, returning what direction
.I src
needs to be moved to reach
.I dst
or
.B Err
if it can't be reached in one move.
.I domove
and
.I doput
are used by clients to handle actions for glenda
and trapper (the player who puts the walls).
they
returns
.B Wall
and
.B Glenda
if the cell is not empty.
.PP
.I findglenda
returns first cell which has
.B Glenda
inside.
.I checknext
is a depracated varient of
.I pointdir.
.PP
.I score1 ,
.I calc
and
.I nextglenda
are... uh..., functions i guess?
i don't know what they do. they are supposed to be computer's algorithm,
please let me know if you know what's going on!
.PP
.I restart
reverts grid layout to
.B ogrid
and sets turn to 0.
.I undo
undos to last move done by tapper, sets
to
.B turn - 2.
it's expected to be buggy, and only works once.
(further calls to
.I undo
reverts the map to orignal state before first call of undo.)
.I checkstate
checks whetever game has finished or not, and who has won.
