that's great, you have much more strength and perseverance, i undid my
change :)

i've put out a new .tgz of sokoban with a few changes:

	- level parser added -- works on the plaintext files from
	sources.se/sokoban. no more hundreds of level files.

	- a new, easy levelset loaded by default

	- change between the easy and hard levelsets via the third
	mouse button

	- sokoban now accepts a level file as argument

	- the game now resizes to show only as much as the level
	covers, this is much better than the previous 16x16 grid

enjoy :)

ps: russ, do you think it's a good idea to put the images and the
levels in /sys/games/lib/sokoban and to create a /sys/src/cmd/games/
section so the game could go on sources.cs?

Re: [9fans] sokoban

[geoff]

The canonical location for games source is /sys/src/games.

Is this game sokoban倉庫番 game source is original?
I'm not a game user, and I have no knowledge on it though...

This is called as a hack.  But is there an official way
to recognize the hiding in rio?

i think that's the only way.  i had a look through rio's source before
doing this and the window hide function sends a Resized message with
ZR as the argument.  ZR is the (undocumented) rectangle variant of ZP. 

even though you won't see it set anywhere in either rio or libdraw's
sources, ZR = Rpt(ZP, ZP).

i had hoped that eresized's 'new' argument would be set to 0 in the
case of window hides but it's always 1. could that be a bug?

Where did you get these levels?  These are harder than
usual sokoban levels, i think.  Glenda should need to work real hard.

By the way, what kind of game do 9fans' member play on pc usually?
Russ suggested Fish Fillet in his post.  Are you all gaming with
kernel hacking?

www.sourcecode.se/sokoban -- they're the 120 level set listed as 'the
ones from gameboy', they could be the harder ones?

suggest better sets and i'll put them in first...

i hadn't played them before i let the game out -- i'm not a very avid
sokoban player :)

ahh, yes, now i see -- there's a different levelset 'boxxle 1' which
appears to be the easy level gameplay...


i'll fix the game to center on the screen, write a parser for the
level set to avoid all that mucking around with files and make a new
release...

sometime tomorrow :)

fish fillet reminds me a lot of kernel hacking.
it's a great puzzle game, just like sokoban.

i'd rather be kernel hacking.

i think level 2 was wrong!  i was stuck on it too, but passed the next
few levels.  i've changed a single location to make it more trivial:

plan9% cat sokoban/levels/2
  ####
  #  #
### $####
#@$..   #
#  .* $ #
###  ####
  #  #
  ####
plan9% 

or you can just download the new one from the web.. the solution now is much easier.

Re: [9fans] sokoban

[Russ Cox]

that's excellent!  i was going to suggest that.
a really nice addition is that you click on a ball
and a desitnation square, and if glenda can move
the ball there without touching any others, she
does so automatically.   it's a lot nicer than the
"click one square at a time" once you get to
higher levels.  i may add that later if no one beats
me to it.  the search is not completely trivial,
but not so hard.

also i've been recently playing fish fillets
(http://fillets.sf.net), which is to sokoban as
chess is to go.

at http://plan9.cs.utwente.nl/sokobanupd.tgz you will
now find something that might be seen as a first step
towards that, although slightly different in nature.


If you click on a destination square then the following may happen:

If
 - the destination square is on the same row or column as glenda, and
 - there is a ball next to glenda
   (in the direction of the destination square), and
 - all squares between the ball and the destination square
   (where glenda will move) are empty, and
 - the square next to the destination square where glenda will
   push the ball is empty too, 
then glenda will move to the destination square, pushing the
ball while moving.

Otherwise, if glenda can go to the destination square
without touching anything, it will do so.

Otherwise, nothing will happen.


I found this working pretty well, although sometimes
I do not get what I want (a 'push' instead of a 'walk'
or the other way around). Russ' suggestion may work
better in practice (but I only looked up his suggestion
to type this message - after my hacking was already
kind of completed).


The search algorithm is pretty simplistic;
it can be seen in action by toggling the 'animate' entry
in the button 3 menu. 'noanimate' disables animation.


The .tgz file contains an updated version of the files in
/sys/src/games/sokoban - this seemed easier than providing
it as a diff or patch - just unpack in a new directory,
mk and run the result.
there are small changes in sokoban.[ch] and mkfile,
the multi-step stuff is in new file route.c.
If it is seen as an improvement, integration in any
form with the version on sources would be fine with me.


Enjoy!

Axel.

YAMANASHI Takeshi submitted some nice fixes for the maze game
yesterday and suggested that a sokoban variant may not be a bad
idea...

several hours later i ended up with:

	http://pages.cpsc.ucalgary.ca/~mirtchov/p9/sokoban/

it has 120 levels and is fully playable (much more so than the maze
game)...

hope you enjoy it :)

I like it. Thanks!

Re: [9fans] sokoban

By the way: The sokoban window is not hideable. There appears an entry
"sokoban" in the list of hidden windows but the window still remains
visible (and the game remains playable).

fixed that just now: sokoban won't attempt to resize if eresized() is
called with the same screen rectangle. it's a hack, but that's really a
problem with how i designed things.

there graphics are also sharper now -- i found a better source for the
level sprites (see the screenshot).
