I have decided to give names to all of my alpha updates going forward. I have chosen to follow a movie theme naming convention. I am therefore proud to announce the “Primer” update (Cannonade 0.5.9). Aptly named, this update finally adds the timeline scrubbing feature! This feature allows you to pause and restart the game at any point in the past by dragging the timeline slider and hitting the play button. Perforated glass doors quickly shut and you hear the low hum of time travel occurring in the background. Once the universe has temporally moved to your desired point the doors open and you can watch history repeat itself!

Complete Changelist:

• Bumped engineCompatibility to 0.5.9. (this means all games previously created by versions <= 0.5.8 will be deleted)
• Got the timeline scrubbing working!
• Added a neat glass door progress indicator when you jump through time.
• Moved auto-camera to only be active during opponent’s turns.
• Did a top to bottom redesign of the cluster menu
• Added basic OpenGL lighting to blocks.
• Added an initial pass of the intro sequence.
• Moved the castle picking view to one-quarter height up.
• Used glPolygonOffest to correct decal the friction splatter.
• Changed the editor so that it moves the camera to the half-height everytime the blocks change.
• Baked the current levels and fixed some bugs related to baking.
• Added history grabbing functionality.
• Fixed a lot of bugs related to observing various points in the timeline.
• Modified the project so that I could submit a dummy IPA to iTunes Connect so I can keep my identifier (I hope).
• Made a new Pad+Phone based experience.plist.
• Changed the level’s info format from a serliazed file to an NSDictionary/plist.
• TONS of changes aimed at making it easy to integrate art.
• Removed the individual block textures now that the atlas is working everywhere.
• Pulling demo/intro values into the experience.plist.
• Initial demo intro game type implementation.
• Added a dummy account loging pragma (LOGINASAORENTEST1).
• Minor tweaks.

Alpha Testing List

Would you like to be one of the awesome alpha testers that help make Cannonade great? Send an email to: [email protected] and I will reply with instructions on how to get onto the Trac server, Testflight list and tester forums.

The focus of this update is the new in-game tutorial! Now when you first launch Cannonade if you have never run through the tutorial it will prompt you to do so. The tutorial level is meant to teach new players how to use the battle interface and get them some target practice with the fundamentals. Give it a whirl and let me know what you think!

Complete Changelist:

• Bumped engineCompatibility to 0.5.8. (this means all games previously created by versions <= 0.5.7 will be deleted)
• Initial implementation of the tutorial game type and level.
• Made some menu refinements and added a “Wiki/File A Bug” menu option.
• Made it so that you are prompted to run through the tutorial if you havn’t before on that device.
• A few quick menu sound effects.
• Added detailed statistics gathering.
• Fixed lots of little simulation execution bugs.
• Tons of leak hunting.
• Added friends info to the game server packets and cleaned up the server code a bit.

For the past week I have been working on creating a gameplay tutorial mode for Cannonade. I am pretty pleased with how it has come out! There are still enhancements to be made and polish to be applied but I think it is good enough to put into the next seed. It is meant to explain the interface and get you some basic gameplay practice before you go up against real people online. It reveals the interface step by step, explains how you use it and lets you get some hands on experience with each concept as it is introduced. If you have never completed the tutorial before then it is the first thing that runs when you launch Cannonade. Previously the only way to figure out how to play was to just press buttons and experiment around after you had already entered a game with a real person. Hopefully by adding the tutorial I can help teach people about how to play the game before they play for reals.

The two most note worthy changes in this build are SPEED and WEAPONS! After spending two days on physics performance optimization and a week and a half on graphics performance optimization Cannonade now runs a lot faster on both the iPhone and the iPad! There are still speed gains to be had but the framerate difference is like night and day. Thanks to your voting, in this build we also have the debut of the Gravity Bomb, Fire Bomb and Friction Bomb weapons. They still need to be tweaked and balanced but they are still fun to play with. Give them a shot!

Complete Changelist:

• Bumped engineCompatibility to 0.5.7. (this means all games previously created by versions <= 0.5.6 will be deleted)
• Did a lot more investigation into physics performance. Content with how much I have for now.
• A HUGE graphics performance related commit.
• Added the Gravity Bomb, Fire Bomb and Friction Bomb weapons.
• Added powerSlider tuning buttons
• Added a block override fade timer
• Added all sorts of neat effects to the gravity, fire and friction bombs.
• Added a new lava island level to design around the !FOGENABLED and NONBLENDEDLAVA speedups.
• Initial “connection-less” Game Center implementation. Initial support for key-based communication (added libcrypto.a)
• Added a label toggle button in game and removed the reticle label fade.
• Reworked the visual styling of the shootMenu.
• Abandoned scrolling on weaponScrollView because UIScrollView is too buggy.
• Added BlockAttachements.
• Added CANNON_IMPACT and BLOCK_POOF emitter types.
• Tweaked Gravity Bomb effects.
• Removed old levels.
• Fixed a bug where resetCollisionFilters was not being called (killed replay).
• Extended ASGlassButton to handle corners.
• Fixed some ASGlassButton issues that were causing uneccessary redraw.
• Added a biased decal shape as a hack until http://aorensoftware.dyndns.org:8000/TRAC/ticket/145 gets fixed.
• Refined convex sweep tunnel protection even further.
• Added convex sweep querying to block movements as well.
• Added LOCALMODELVIEW so that we don’t stall OpenGL everytime we need to read/update the camera matrix.
• Added more benchmarking oriented functionality and updated libbullet.a.
• Tweaked build settings and switched compilers to llvm-gcc4.2.
• Fixed the editor back into working shape.
• Fixed cull and texture state for projectiles until they get their real objects.
• Fixed big in terrain removal code that was smashing memory.
• Fixed some block label override bugs.
• Fixed key loading.
• Fixed projectile state dirtying.
• Added an in-game fps counter.
• Added server games auditing to the ADMIN_MENU.
• Checks first before copying into history now.
• Misc bug fixes.

Even though many of you already know about my current project (I have also written a few blog posts about it) it is time to officially announce it and give it a quick introduction. The first project that I have chosen to work on since going indie again is an iOS game called “Cannonade”. It is a turn-based physics game with an emphasis on multiplayer and creativity. So far I have the core engine up and running. I have chosen to use the Bullet3D engine for physics simulation because of it’s general support and stability, iOS support and iOS performance. The rendering and effects engine, UI, networking engine and everything else I am writing from scratch myself. I am basing enough crucial functionality on iOS specific components (like UIKit and Game Center) that I can say with good confidence that it is going to be an iOS exclusive (although some parts of the engine may make it to other platforms). It is currently in early Alpha and there is a lot of game design and asset creation left to do. Things are still very malleable and everything is still placeholder (please keep that in mind when playing test versions and viewing screenshots 😉 ). I have a comprehensive testing plan, work schedule and timetable which I am hoping will ensure that Cannonade becomes a polished, high quality product by the time it hits the App Store.

Testing out some new explosive weapons in the editor.

So after a month and a half of heavy development I am almost ready to unveil my game to the world and start alpha testing! There are just a few things that need to happen first though, the most important of which is that I need to find a name for this thing!

This game is a creative 3D physics game in which players take turns trying to destroy each other’s fortresses with different weapons and strategies. Players need to be clever in their choice and use of weapons, strike a balance between spending and saving resources, and have a pinch of luck to succeed. Players can even take their game to the next level by creating their own castle designs and pitting them against their friends.

Thematically I have been thinking that I want it to have a light-hearted, silly and fun tone to it but also have tons of big explosions and loud weapons.

So what should such a game be called? (pick up to 5)
Got an idea for name? Let me know in the comments!

UPDATE: Voting is now closed. I have decided to go with Cannonade! Thanks for your input everybody!

One day while I was hard at work a couple weeks ago I hit a really difficult technical snag. I stood up from my desk, let out a sigh and declared to the other person working in the office that “I’ve lost my determinism!”. He then inquired how I had lost my motivation while visibly wondering if I had used the word correctly. Although I had hit a significant roadblock, my determination to overcome it and make progress on my game was higher then ever. The “determinism” of my game however, had been lost. Now I needed to take it back.

Interested in startups or startup culture?  If you live in or around the Bay Area you should come to a monthly event that my friend Derek and I started a couple months ago called The Startup Grind.  The event is held on the last Thursday of every month (except when holidays conflict) at 7:00 at the Vaporware Labs office in Mountain View.  It has two main purposes.  The first is to hear talks and presentations by experienced entrepreneurs, VCs and others involved in startup culture or business.  The second is to network and chat with other people just like you who may be in the thick of starting a company, provide services to entrepreneurs or just like to discuss cool projects with interesting people.

The Startup Grind Meetup is free and there is always pizza and drinks (although if you are so inclined you can make a donation for the pizza).  The next meetup is exactly one week from today and will feature a talk by the CEO of Smule, Jeff Smith.  And in February we have Jason Calacanis on the schedule to speak. All are welcome so feel free to drop on by!  When Derek and I started the event it was just a couple of friends brainstorming interesting ideas.  Now as of the latest count we have 126 committed to attending the next meetup!  It has grown faster than either of us would have guessed and it looks to have a really bright future!

The biggest problem I see with the current implementation (iOS 4.x) of Game Center is that there is no way for Game Center users to authenticate themselves to 3rd-party servers. Let me explain from the top. Game Center is Apple’s new games oriented social network and infrastructure on iOS devices. It has a lot of great features like leaderboards, achievements and matchmaking. Once a user creates an account on an iOS device they are perpetually signed in at the operating system level. This is great because it means that all existing and future Game Center games can take full advantage of its features, social connectivity and never have to make users create an account (users HATE creating new accounts) or even sign in again (unless of course they explicitly sign out). From the game developer perspective, Game Center is really awesome. There are a lot of developers (myself included) who do not want to have to:

• Create a complete login infrastructure
• Store and handle people’s passwords safely
• Figure out some sort of account confirmation
• Implement password recovery
• Encourage users to start building YET another social graph on your service/game
• Handle other support related support requests

The entrepreneurial itch has gotten me once again! After nearly five years with Apple I have decided it is time for a new adventure! In many ways I think I prefer to be the big fish in the small pond. As far as the startup life is concerned, there has already been so much said by so many that I don’t think I have anything particularly insightful to add other than that it is indeed an absolute rush.

The first time I went out on my own was right after college. For two years I developed an extensible 3D interface framework and window server called Vision. It is no longer in development but you can still check out material on it in the Archives (I might get a patent out of it yet though). Even though things didn’t turn out like I had hoped, I still wouldn’t trade that time for anything! I learned a TON during that period of my life in all sorts of areas. The technical skills and business knowledge that I acquired during that time have proven to be invaluable in everything I have worked on since. The lessons I learned have also shaped my plans for this next go around.

The first thing I decided to do this time was to start small and build up. I am going to attack small problems/projects with the goal of getting some sort of sustainable revenue quickly. These small projects are the kind that one person can bring to market by themselves. Because of the small scale I also plan to not seek funding and bootstrap everything myself. That way there really is nothing standing in the way of getting a fully finished product out the door other than my own skill and effort. Hopefully I will be successful enough to bring others on board and attack progressively bigger problems.

I have already laid the plans out for my first project which will be introduced in a future post. I will say that it is an original iOS game like nothing currently in the App Store today. My plan is to take this first month to code up what I would comfortably call a playable alpha and start organizing a testing community around the game. Apple has made such compelling and easy to use development tools/frameworks that it is going to be a joy to dive headfirst into iOS development full-time.

I also plan to regularly document my progress and efforts here for anyone who has interest in independent software development. I know that I particularly enjoy reading about the experiences of other indie developers out there. Got any advice for me? Let me know in the comments!
