sdl pacman clone

schuay · 2008-11-21 22:42:55

while learning c++ i started writing this little game - first using allegro, then a rewrite with directx, now a quick and dirty port to linux using sdl.

* pacman clone
* skinable
* level editor included

pacman usage:

commandline arguments
--help:         show this message
--level <lvl>:  start with selected level
--skin <skin>:  start with selected skin
--editor <lvl>: start in editor mode.
                if a levelname is given the editor loads and saves to that level

ingame
esc/q:  quit
arrows: movement
space:  boost
p:      toggle pause
n:      new game
l:      switch level
s:      switch skin
e:      enter editor
w:      (in editor) save map
f:      toggle fps display
h:      view highscore

the game is in a playable state - but there is tons of room for improvement und it's not exactly userfriendly
an editor is included but it suffered alot during the transition from having a menubar in windows to not having a menubar in linux (couldn't find a good way to do this using sdl)

the most urgent issues would be
* improve performance on lowend pcs
* compile this for windows ( and iphone and android and windows mobile and make tons of cash )
* making the paths to image/config/sound files err.. a little less sensitive (atm you will get a segmentation fault if you don't start the game from the pacman root dir).. this should be very simple.
* make the level editor easier to use .. at the moment it's a pain

install:

* this is now available as a PKG called pacman_sdl in the AUR, see below for link

AUR:
http://aur.archlinux.org/packages.php?ID=28014

github:
http://github.com/schuay/pacman/tree/master
git://github.com/schuay/pacman.git

windows version:
http://github.com/schuay/pacman/downloads

if anybody likes the game, great. if somebody improves on it, awesome. if nobody cares, no harm done

just tried this out.. nice job

pyther · 2008-11-22 00:25:07

How could I go about compiling this on x86_64?

+1 to above. Your binary is 32-bit, and there's no Makefile in sight? I see a CodeBlocks workspace file, but without CodeBlocks?

edit: makefile + pkgbuild are now included in the first post

here you go.. hope it works for you, first time writing a makefile

CC=g++
SOURCES=Settings.cpp Pacman.cpp Main.cpp Log.cpp hScore.cpp Ghost.cpp Game.cpp Error.cpp BckgrObj.cpp BHeap.cpp App.cpp
OBJECTS=Settings.o Pacman.o Main.o Log.o hScore.o Ghost.o Game.o Error.o BckgrObj.o BHeap.o App.o
LIBS=-lSDL_ttf -lSDL_gfx
EXECUTABLE=pacman_v4

all: 
    $(CC) -c `sdl-config --cflags` $(SOURCES) 
    $(CC) `sdl-config --libs` $(LIBS)  $(OBJECTS) -o $(EXECUTABLE)

clean:
    rm -f $(OBJECTS)
    
uninstall:
    rm -f $(EXECUTABLE)

Nice work with this, maybe you should host it on a GitHub account so people can fork

Done! The link is in the first post.

omg.. i thought "huh? sdl package management?"

schuay · 2009-07-05 09:44:42

Added to AUR at http://aur.archlinux.org/packages.php?ID=28014

Might do some more work on this soon!

( Sorry for bumping my old post )

Edit: Enabled sound and fixed transparency issues.

Hey, nice game.
I'm writing something similar in SDL and was wondering how you did the AI for the ghosts, what kind of algorithm did you use?

djszapi · 2009-07-11 13:00:55

+1

It's really nice new revision of well-known old games, and much faster than the 3d version of it.

Thank you for everything!

I'm glad you liked it, thanks for trying it out

I wrote most of this a loong time ago and I can't remember most of the implementation details. But the source code is available here: http://github.com/schuay/pacman/tree/master
The AI is contained in Ghost.cpp, take a look at the pathCalcNormal, pathCalcVuln, and pathCalcDead functions.

Edit:
It's pretty primitive actually. During the loop, a specific location is set as the target for the ghosts. 2 of them are set to pacmans current location, the other 2 to pacmans next intersection.
Every time a ghost reaches an intersection, it has a certain chance of NOT choosing the fastest way to its target location. This chance goes down the closer it is to its target, so once a ghost is hot on your tail, there's a good possibility that it will keep chasing you instead of wandering off. Pathfinding is done with a bheap, the logic for that is partly in Ghost.cpp and the implementation of the bheap itself is in BHeap.cpp.
