Here's a news that will make a lot of people happy: PewPew 2 is in development! It will feature (among other things) new game modes unlock-able by completing some levels (there's a campaign mode), additional sound tracks, and medals and ships to earn. The release date of PewPew 2 is "When it's done", but I hope to finish it before March 2010. Programming the levels in the campaign mode is one of the task that is taking me the most time. I want all the levels to have a distinct look as well as a different gameplay. Right now, creating one level takes approximately one week (20% of the time is spent creating the level, 80% is spent polishing it)... Of course, if you have any ideas or suggestions for PewPew 2, feel free to send me an email (jfgeyelin@gmail.com) or post a comment.

And the scores are pouring in... can you guess when did Apple publish the update? So far, I've used 0.6% of the maximum CPU load (and 0% of the bandwidth), so I should be OK!

PewPew 1.2 should be accepted anytime now, so the scores are going to start to pour in... luckily I have just completed PewPew's website: http://pewpewgame.appspot.com/ . The most important features are the score board and the forum . I made the score board myself in python , and found the code for the forum here . The forum is pretty cool, because it allows you to post with your Google account, or without login at all. Everything is hosted on the Google App Engine, so if the traffic stays under a limit, I will never have to pay for the servers, and the website will stay up and running for ever. According to my estimations, I can handle 100 000 score submissions per day without paying for additional bandwidth. Since "only" 50 000 people have installed PewPew, I should be fine. I have no idea what to expect regarding the CPU utilization, but I have cached a lot of database calls, so I should be OK. At worse, I might have to pay 1 or 2$ per day during the first week; after...

I uploaded the 1.2 update to PewPew yesterday. I have been working on it for several weeks, so there's a lot of changes! First of all, there is a new game mode! I was not planning on adding one right away, but the survey made me change my mind. I won't spoil the surprise about how it's played, but I guarantee it is without a doubt the best mode yet . Not shown here: insane amount of enemies . Secondly, there is now an online high score board! In a couple of days, I will post about a small website with all the scores. Thirdly, all the old game modes have been tweaked: I added a bonus to reward speed in "Dodge This", and there is a new type of enemy in "Assault". Of course, there are some small new optimizations that should improve the frame rate a bit on the old iPhones and iPods Touch. Here's the complete list of what is new: new game mode, called "megagore" online scores the possibility to move the camera freely when watching a replay th...

In PewPew 1.2 (not yet released), you can colorize you nickname. It uses what I call the "Quake 3 text color convention". Indeed, in Quake 3 you could colorize your nickname by inserting "^X", where X would be a number between 0 and 7. Each number was associated with a certain color. For instance the nickname "^1Hello" would appear red. "^4World" would appear blue. You could even do combinations, like "^1Hello^4World". Well the same thing is possible in PewPew 1.2, except that there are more colors to choose from. The new feature in action Here is a picture showing each color, with its associated symbol: I hope this will result in a colorful online score table! (more on that later).

I had exams, so I could not really work on PewPew, but now I am back. Let's take a look at the survey results. There were 46 responses, and I started having responses only minutes after I posted the link on touchArcade's forum. One cool thing is that they appear in real time, in a spreadsheet. Well done Google. And wow, I can actually copy paste the generated summary into this post. Here we go: The game modes are pretty even, though it would appear you like shooting more than dodging. What is your favorite game mode? What is your least favorite game mode? I find the music excellent, and you seem to agree. That's good because the composer is not cheap, he earns 50% of the profit* made with PewPew. The soundtrack is available for free by the way. How would you rate the music? Very poor Excellent Ah! Google is not perfect after all, they messed up the parsing! That's about all we learn from this question, because I already knew that I am good at making a game balanced. Th...

I am currently working on the update, and I'd like to have a bit of input from the players. It's totaly anonymous and very quick (7 questions). Link to the survey

I first started programming PewPew on Linux, with portable librairies (OpenGL/SDL/libcurl). Of course, I had the iPhone/iPod touch in mind, so I designed the gameplay and the UI accordingly. After a month or two (once I payed for the $99 for the SDK), I migrated to Xcode and the iPhone OS. I'll write a post about that later because it was not as simple as I imagined it would be. A week ago, I migrated the code back to Linux, and this time it only took a couple of days :) The goal was to make PewPew prettier by giving the lines a glowing look (like geometry wars) by using the infinite power of my computer (compared to the iphone anyway). Perfection. Naturally, at first I failed :-) My first idea was to draw the lines multiple times, with different width and different transparencies. Here's what it looked like: Not perfection. Okay so that was ugly, but it had to be done. The second idea was to use pixel shaders. A pixel shader is small routine executed on the graphic card, that...

PewPew v1.1 is finally out. I have not received any crash report (yet?), so the update code seems to work well. Also, it seems that people appreciate the new game mode =)

First of all, I am happy to announce that App of my Eye reviewed PewPew : [...] the biggest praise we have for this game is it’s controls, which are very responsive and just feels great overall. If not THE best controls that we’ve ever had in an iPhone game, definitely one of the best. Other publishers/developers should take note. A must-have app for every level of gamer and amazingly, it’s free. Secondly, last Friday (the 19th), I submitted an other update. Let's hope Apple will validate it more quickly than the last one I submitted! The most important changes in the new version (PewPew v1.1) are that: The difficulty increases more slowly in the Assault mode . Because the gameplay changed a little bit, the replays you did are incompatible: you will not be able to watch the replays you made in PewPew v1.0 . I am sorry, but it was just too complicated to maintain compatibility. I finally added a new mode, Chromatic Conflict . In this mode, you can change the color of your ship. D...

Okay, so I submitted the update two weeks ago, and it is still "In Review". I had not realized my update was so big it required 2 weeks of attention. So I canceled the update, because right after it would have been accepted it, I would have submitted a new one, and I am pretty sure Apple wouldn't have appreciated it.

When you modify some of your ressources files in a xCode project, the bundle does not get updated until you modify some port of the code (or do a rebuild all, which takes a while on bigger project). So here's my (ridiculous) work around: mac:~ jyaif$ while [ 1 ]; do touch /Users/jyaif/PewPew/Resources/data/boo; rm /Users/jyaif/PewPew/Resources/data/boo; sleep 5; done In other news, I am still waiting for my update to get approved. I suspect Apple takes this long, to discourage devellopers from updating their apps too often, as this would force them to hire one or -god forbid- two additional testers. In totally unrelated news, I installed and tried the Android SDK :o

I uploaded an update of PewPew. From what I read, it will probably take a week or so for the game to be available on the App Store. Anyway, PewPew now: encourages doing the tutorial when playing the game for the first time asks for confirmation when quitting a game permits the activation/deactivation of rotation during a replay makes it visually obvious to the player that he has taken a bonus has a lower amount of particles has prettier explosions puts the game in pause when a low battery alert (or a music menu pop up) appears ignores replays that can no longer be played make the difficulty increase more slowly in the "Assault" mode respects the players that are listening to their own music :) Under the hood updates: versioning system for the scores precalculation of the explosions needed models are loaded at the beginning of a game (to avoid ingame slowdowns) externalized descriptions of the game modes What I should have finished: The 3rd mode An obvious optimization to the ...

Yesterday, I made PewPew available in all countries, except the english-speaking ones (US/Canda/UK/Australia/Ireland...)

The downloads, so far.

Here is the current list of tasks I need to do before releasing an update for PewPew: force/encourage doing the tutorial when playing the game for the first time ask for confirmation when quitting a game permit the activation/deactivation of the rotation during a replay make it obvious to the player that he has taken a bonus load some of the needed models at the beginning of a game (to avoid ingame slowdowns) somewhat precalculate the explosions, and reduce the number of particules make the explosions more spectacular put the game in pause when a low battery alert appears create a versioning system for the scores i gnore replays that can no longer be played externalise the modes descriptions finish the 3rd mode make the difficulty increase more slowly in the "Assault" mode optimize [a small] part of the collision detection Green = done Red = might not be done

Overall, the ratings are decent, and the reviews are good. It is a good surprise, since this game is really not for casual gamers. I expected more people to not understand/like the game, and subsequently give it a poor rating. I expect the average rating to decrease though, as unsatisfied people uninstall the app and give it a 1 star rating.

Ca y est, PewPew est disponible sur l'appstore Francaise/Belge/Luxembourgeoise d'Apple. J'ai crée un groupe de discussion pour pouvoir parler de PewPew, là . There, PewPew is available! Since I released PewPew only in France/Belgium/Luxembourg, this post is be both in French and in English. To ask questions/talk about PewPew, go here .

Date Submitted: 01 May 2009 Release Date: 01 May 2009 Status: In Review Now, we wait.

It is possible! You only need to copy two files in the correct directory: LuaXcode3SyntaxColor.zip (found at Capgo's website via lua-users.org) Update: after installing this, Xcode started crashing regularly, and at one point I couldn't even send the game to the emulator anymore => I removed the files.

Added: -Lightning on the main menu -3D cube transition between the menus/screens -"About" screen -Pretty joysticks -A new mode (shown at the end) that totally rocks -Scores -Menu to display scores and launch replays -Hashes to verify the integrity of the scores -Preferences -An in-game menu -Lower case characters -Scrolling background that can change color. -Music -A rotating camera when watching replays

Added: splash screen, a decent icon, and REPLAYS. Here I am showing the two first modes (using the brand-new replay system)

Bam. One of the modes playable in the game. Needs to be tweaked to become fun.

Added space partitioning, allowing efficient collision detection between the player, the ennemies, the bullets, and the walls.

Just for kicks I enabled addiditve blending which resulted in... ABSOLUTELY NO LOSS OF FPS. Shown here are spherical explosions (200 particules per explosions), still at 60 fps. I captured the video filming the simulator because I was hoping the quality would be better than when filming my ipod (the pixels on my computer screen are larger).

I added a lua interpreter. The graphics (font/ship/background/bullets) are loaded from lua scripts. Also, openGL is now set up for 3D graphics (before, objects far away from the camera were as big as the objects near).

There, the ship can shoot bullets. I also added explosions, and they aren't slowing down the fps either :-)

I mostly cleaned the code. Also, the camera follows the player, and you can control the shield.

Pheww, finally managed to run some code on my ipod. The left "joystick" doesn't do anything, it's there just to prove I can handle multi-touch.

This blog is dedicated to the development of the PewPew , an iPhone game I am programming.
