Hi Anton/Andrew
I guess this is the most likely answer, but I can't see it.
The working program with the resizeable game board is at
sites/compkarori/gorim2.r
( http://www.compkarori.co.nz/reb/gorim2.r )
which saves the file
http://www.compkarori.co.nz/reb/gomoku4.r to the local drive
as %gomoku3.r and executes it
In gorim2.r, there is no code left that alters the value of
'cellsize.
'cellsize is defined initially as 20 in gomoku4.r
It is only redefined in the function 'resize-board ( in
gomoku4.r ) which is executed on receiving a resize event
This is just the first part of the function as it is quite
long
resize-board: func [ size [pair!] /local x ] [
bk/size: size
cellsize: to-integer ( size/y - 60 ) / 20
; print [ "new cellsize: " cellsize ]
init-variables
...... ]
and this is the first part of 'do-preview
do-preview: func [ act pos /local x y tmp tmp2 tmp3 topedge
result ] [
cellsize: gridsize/x ;!! have to do this as somehow
keeping the old value of cellsize
print [ "Cellsize: " cellsize ]
..... ]
It works correctly with the assignment I make in the first
line of the function, but it bothers me that I have to do
it.
If you want to see it, just uncomment the two print
statements, run gorim2.r, and then when you're logged on to
the chat server, click on the "send" option on the menu.
That brings up a board. As you move the mouse over the
board, it will start printing. Resize, and it will print
the new cellsize, but without the reassignment, the cellsize
remains the same ...
