[lisp-game-dev] My first version of Bourtange (a planetary fort defense game)
by Schell Scivally 01 Aug '10

01 Aug '10

Hi guys. First off I wanted to say thanks for helping me with my initial foray into lisp development. That said, I wrote a blog post detailing my progress on the game so far. If you'd like to read it at my blog, it's here: http://efnx.com/lisp-game-progress/. For those less click happy I'll post it in this email (hopefully the formatting doesn't get all wacked out): So after my first (almost) 30 days of learning lisp<http://efnx.com/lisp-game-competition/>, I have a playable game. The gameplay is a cross between tower defense<http://en.wikipedia.org/wiki/Tower_defense> and orbient <http://en.wikipedia.org/wiki/Orbient>. You control a planet-base (the core) in the center of the screen. This core comes equipped with one weapon, the core-blast. Enemies are generated at the edge of the screen, in the spawning-belt, and are drawn toward your core by gravity. When enemies collide with the core, the core looses life. Life is displayed as a green outline around the core and when your core is out of life, it explodes. When an enemy dies, which happens either by colliding with your core, being hit by a blast or being thrown past the spawning belt, you gain resources. Resources are displayed by purple boxes in the upper left. You can spend these resources on extra cores and weapons in the weapon-store, which is displayed in the upper right. Below is a screen shot of the game in action. [image: Screen Shot]<http://efnx.com/domains/efnx.com/wp-content/uploads/2010/08/Screen-shot-201…> A lot of work still remains to be done, but I hit the 30 day deadline with this first draft. Luckily, the contest hosts have extended the due date<http://dto.github.com/notebook/2010expo.html> to August 10th. By then I plan to fix some bugs, add more weapons, enemies, a game-over screen and do some optimization. I feel accomplished after learning lisp, though I know I’ve only seen the tip of the iceberg and have found my new favorite language. To the hosts of the competition, thanks! You guys have made me a better programer. The source to the game is here<http://github.com/efnx/kabukitheatre.bourtange> and you can download and build the game as you please. Send me a message with your thoughts on my game or my code! -- Schell Scivally schell(a)efnx.com (efsubenovex(a)gmail.com) http://efnx.com http://github.com/efnx

[lisp-game-dev] Compiling and saving a binary
by Schell Scivally 27 Jul '10

27 Jul '10

Hi guys - my expo game is coming along nicely, but I'd like to compile a binary. In my main.lisp file the code that starts everything looks like this: ; above is a bunch of opengl functions for the game (defun main () (glut:display-window (make-instance 'my-window))) Then, in another file, build.lisp I have: (load "main.lisp"); (sb-ext:save-lisp-and-die "bourtange" :executable t :toplevel 'main) When I run my build script the error I get is this: [undoing binding stack and other enclosing state... done] [saving current Lisp image into bourtange: scanning space for lutexes... writing 6416 bytes from the read-only space at 0x20000000 scanning space for lutexes... writing 8032 bytes from the static space at 0x20100000 scanning space for lutexes... fatal error encountered in SBCL pid 19099(tid 140735077362720): no size function for object at 0x003f1be0 (widetag 0xe0) It's a little cryptic (since I don't know what's at 0x003f1be0) and there aren't a lot of leads on google. Does anyone have a quick idea of what I might need to do to compile this binary? Thanks guys. -- Schell Scivally schell(a)efnx.com (efsubenovex(a)gmail.com) http://blog.efnx.com http://github.com/efnx

[lisp-game-dev] Announcing official lispbuilder-sdl-binaries downloads for OS X
by Elliott Slaughter 27 Jul '10

27 Jul '10

Hi everyone, Over the last couple of weeks, I have been working on providing lispbuilder-sdl-binaries for OS X which allow people to get up and running without needing a working C compiler. I am happy to announce that these binaries are now available at the following link: http://code.google.com/p/lispbuilder/downloads/list?can=2&q=mac-lispbuilder… For those of you who want a simple install, just extract these archives over your preexisting lispbuilder-sdl install. (They only contain C binaries, and not the Lisp source code.) TODO: Make them asdf-installable. Shouldn't be hard, now that they work. The gory details: See the application-builder mailing list archives. -- Elliott Slaughter "Don't worry about what anybody else is going to do.

[lisp-game-dev] New game: lispac
by Mario Castelan Castro 25 Jul '10

25 Jul '10

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 July 24th 2010 in lisp-game-dev(a)common-lisp.net thread "lispac (New game)". Hi. Based on an anonymous contribution I'm writing a game similar to the classic Pac-Man in Common Lisp using the lispbuilder-sdl library which I would like to add to the Lisp Games Expo 2010 if possible. It isn't playable yet in the sense the game can't be fully controled by the GUI. It's nessesary to use the REPL to configure the settings and load a board for example, but the engine is fully functional, though not finished. The first playable release is planned to be in 3 days, in July 27th. I will also publish screen shots and so. Suggesstions are welcome. lispac is hosted in GNU Savannah: https://sv.gnu.org/p/lispac. Source code is available via GIT in git://git.sv.gnu.org/lispac.git. Web page (Void by the moment) will be http://www.nongnu.org/lispac/. lispac is free software released under the GNU General Public License (http://www.gnu.org/licenses/gpl-3.0.html) version 3 or optionally any later version.

[lisp-game-dev] [PROGRESS] Engine Troubles over Tentacle Planet, part 2
by Erik Winkels 22 Jul '10

22 Jul '10

Blogged here (with video): http://aerique.blogspot.com/2010/07/ilge-2010-engine-troubles-over-tentacle… 1 Progress ~~~~~~~~~~ Since the last report I've added: a controllable spaceship, bullets, tentacles and I made an unsuccessful attempt at producing a Linux binary. For the controls I use the OIS library. I was already familiar with this due to my clois-lane library. The controls work but don't feel quite right yet and need some minor adjustments. Adding bullets was straightforward. The most time was put into the tentacles and the attempt at making a statically linked Linux binary. The tentacles are Ogre prefab cubes plot along a Bézier curve. The P1 and P2 control points and the P3 end point are assigned a new x,y,z coordinate each frame. This coordinate is picked by walking through 3D Perlin noise with a random movement vector for each point. (The vector was created randomly at creation time, it's stays the same from frame to frame.) The code is a huge mess by now and it is getting in the way. Next priority should be a clean-up. 2 To Do ~~~~~~~ - [X] rolling terrain (high) - [X] controllable spaceship (high) - [ ] improve controls (low): The controls aren't quite there yet, especially moving left and right. - [X] bullets (high) - [X] cmake file (low) - [X] basic tentacles (high) - [ ] shootable tentacles (high) - [ ] collision detection: spaceship vs terrain (high) - [ ] collision detection: spaceship vs all other entities (high) - [ ] tentacles that shoot small spores (medium) - [ ] roaming (bigger) spores that attack the player (medium) - [ ] some minor GUI elements showing the score, highscore and FPS. (high) - [ ] make binary release for Windows (medium) - [ ] spaceship needs to cast a shadow in the terrain to judge heights (high): Solved this by using prefab entities instead of a manual object. - *canceled:* make binary release for Linux (high): This is just too much of a hassle. The Ogre package for Debian didn't come with static libraries and compiling it myself with "--disable-shared --enable-static" didn't produce them either so this is going to take too much time. Eventually I managed to build static Ogre libraries but ran into other problems when compiling with "-static". Statically compiling is something I have no experience with and this looks like it is going to take too much time for the ILGE 2010. For Linux it seems distribution by deb and rpm packages will be the best solution. (What a revelation!) 3 Source ~~~~~~~~ The code for the latest version isn't available yet since it is a horrible mess. Keep watching http://www.aerique.net/software/etotp/ (not up yet) if you're interested. 3.1 Linux Dependencies ---------------------- ECL (10.4.1) configured "--with-cxx". (Feel free to try without it, I haven't.) Debian: libogre-dev ogre-plugins-cgprogrammanager

[lisp-game-dev] [PROGRESS] Browser Lisp
by Eric Bergstrome 22 Jul '10

22 Jul '10

Progress Report #2 My in-browser Lisp has come a long way since the last progress report. * it has support for the following data types: symbols, strings, numbers, conses, functions * it has an online REPL * its compiler is self-hosting * it can inspect and modify browser document nodes and listen to browser events * it can make http requests to the host server * it has some concurrency features inspired by Erlang * it supports resumable breakpoints, error reporting, stack traces, and disassembly It is a Lisp-1 with tail call optimization but not continuations. Macros are unhygienic. It's not exactly the lisp system I envisioned at the beginning and it certainly has used up more of the expo than I had intended to spend on it but hopefully it's good enough to make a game with before the deadline.
