What it is:

Get a head-start for your Line-Drawing game and save days if not weeks of your time! You’ll get gameplay code modelled after the extremely popular Flight Control game. You’ll learn how to draw lines, detect touches on objects, have objects follow a path – and much, much more! Written by a professional game developer and game industry veteran (me) the source code is annotated with lots of comments explaining my rationale and written with readability in mind.

Contains separate iPhone & iPad targets!

The Starterkit includes targets for iPhone and iPad using the same code if you don’t want to create a Universal app, for example to reduce your app’s size or to be able to charge more for the iPad version. If the iPad Target is selected hi-res iPad images will be used. Image selection is done automatically by loading those images whose filenames have the “-ipad” suffix, the same suffix cocos2d uses.

What others are saying:

“Code is quite clearly written and decently documented […] definitely a fine investment.”
From: Commercial cocos2d Code review from Alex Curylo.

“It was an awesome moment when I found the source for a line draw game of this caliber.”
-Franklin Lyons, SpinFall

“Especially the path and movement system is saving me lots of headaches.”
-Martin Hoffmann

    Hey. I like what you are doing, and I appreciate the help. I do feel however that you are inadvertently positing yourself as opposition to the guy who wrote cocos2d. he even went so far as to mention on his blog that he did not ask for your support. Combine that with your discussion about him not promoting starterkits – which I feel is a bad move on his part, and you are likely to take a giant chunk out of his profits, and definitely his motivation.

    Have you considered taking a chunk of the money from sales and sending it his way? Maybe even starting a campaign or store encouraging others to do so? At some point, if successful, this might change his mind to the idea of opening a single shopping-mart for cocos2d kits. You’d be the the guy who wants to help cocos2d, and its developer, who has helped us so much. Not the guy who is competing and hurting him. I respectfully acknowledge the fact that your starterkit move is a) totally legitimate and honorable and b) the smarter thing to do from a business standpoint.

    I suspect, though, you would’ve stayed in the mainstream business if smart business tactics and money was your main interest.

    thanks for listening to this rant,
    Jesse

    • GamingHorror says:

      First of all, thanks!

      As for speculation about profit losses: since I’m selling only to people who want to make a Line-Drawing game, there is hardly any competition. No more than pickups compete for the same customers as electric cars, which means on average close to none despite both being cars.

      It’s also not like that there are only ever 10 people around who would buy a cocos2d source code project just based on the fact that it’s a cocos2d source code project. Instead there are hundreds, if not thousands of cocos2d developers willing to pay for the right project if it were available, and offered at the right price. I’m absolutely positive that none of my customers decided not to buy any of Ricardo’s products because they heard of the Starterkit, and some said they already have bought his products and were looking for more specific/advanced projects to learn from/use. They saw it was a good investement and continue to make such investments.

      Customers make very informed decisions, and at this point the big majority of the cocos2d developers willing to spend money on a source code project simply do not find what they are looking for, and thus do not buy anything, because no one is selling to them. I absolutely believe the market is big enough for more products, but of course eventually those that are executed and marketed better will prevail, but it’s a long way before we’re even close to that. We could actually make cocos2d a better ecosystem if a greater variety of commercial products existed, and that includes more commercial products from Ricardo as well.

      Take a look at the Unity ecosystem and how that works and what great products are offered there, while for cocos2d you can be happy if you find yet another beginner’s Tutorial. And that only happens because developers know that this is going to attract a good number of site visitors as a return of investment. Without a return of investment no bigger and better things are going to get made.

      Assuming that the Starterkit competes with Ricardo’s products and that this hurts him financially is just that: an assumption. I can not stress that enough. Ricardo initially made this assumption, a lot of people simply took that for granted. Please ask him if it really came to be true, he is the only one who can tell. I doubt it made any difference, and so do a lot of people who know something about products and target audiences and business in general. It is sad actually to see that people honestly believe I’m hurting Ricardo without any conclusive or even circumstancial evidence. And it’s even sadder to think that the problem should be the Starterkit, and not Ricardo’s limited choice of products he’s offering, not to speak of the lack of good product promotion, that is losing him money.

      I made over $5,000 within 23 days during the $179 sales period, then made 0 sales since 10 days at $299, so what does that tell us?

      First, there’s enough money to be made if you find something developers want to pay for and offer it at the right price, and then there’s a lesson learned in pricing which shows how oneself can make or break sales much much more than someone else’s product ever could. Unless the sales suddenly keep kicking back, I have to accept that customers voted with their wallets and I have to drop the price sometime soon. And by saying that I probably closed the deal already.

      And then maybe those 30 customers I sold to were 80% of those who would ever buy my Starterkit, and I just happened to have reached almost all of them right away. I still don’t know how many sales per month will regularly be made. This is still open and I’m determined to find out about that and what the influencing factors are.

      As for donating: Ricardo made it clear he wants no affiliation. This includes promoting his software (which I removed) and making donations. When I started out, I wanted to help the developers and that included Ricardo. He never gave me a chance to prove that. I’ll give back to the community for sure, if only spending more time on this website after the cocos2d book is completed.

      I don’t get the part about mainstream business, or what mainstream is, or what that has anything to do with smart (or not smart) business tactics. I never had any “tactics” in mind. I’m selling a product that I’m proud of and helps others make Line-Drawing games. My main motivation to make money from the Starterkit is at the very least to cover the costs of running this site, and eventually to achieve financial independence. I’m in the middle of the two right now. I want to live off doing what I love doing, and most of that boils down to helping others and enabling them.

      I’m happy you took the time to ask these questions. I hope you and everyone else appreciates my honest answer to that. Feel free to ask me more questions.

      • Jesse says:

        That was a very informative and honest answer. I appreciate the well thought out response.

        You definitely won me over on many fronts. I hope the discussion helps others.

        As for “releasing” sales figures, I’m amazed and enlightened, really. I had missed the discounted price, and had found myself thinking I could fork up $150 to $175 just to learn the gems that must be in the code, though I have no immediate plans for a line drawing game. I myself am still at the rag doll end of the spectrum with a (hopefully) fun twist.

        It’ll be interesting see if it’s simply the pricing point the stopped sales. In my case it is. A flash developer (I’m going to butcher his name) Emmanuel furtanado (I think) blogged for a quite a while releasing as many actual numbers as possible about his experiences trying to make income through flash games and the various monetizing schemes. It was well received and oft visited. I hope you do more official blog posts about this, or even publish an Ebook about it. I’d buy it without hesitation.

        Best of luck, btw, and congrats on the book!

        • GamingHorror says:

          Thanks! I definitely intend to write a post about the numbers and someday update the Marketing FAQ with what I’ve learned.
          And eventually I’ll have to write an eAutobiography … but I guess that can wait another 15 years. I’m not old enough yet. :)

    Hi .
    I just read this conversation and I couldn’t help giving my opinion .
    I’ve been following through this little issue for a few days now , more as an individual than as a developer , and I love the terms in which things were said and explained here from both parts ( Jesse and Steffen).

    Beeing educated, polite and honest is they key to success in any field .

    In my opinion , this chain of events is nothing but a natural an usual thing that happens everyday . The market is open to everyone , and fine tuning concepts
    and ideas form other people is not only natural but positive and necessary to make those things evolve.

    I think Ricardo should take this situation as an eye opener and as a motivation to make his world move on the direction he is claimming it should be moving to . Don’t get me wrong, he’s done a lot and we all appreciate his hard work and his help , but in my opinion taking sides is not only childish (no offense intended) but is not helping anyone to keep moving forward to a better situation than the one you were at before .

    Cheers.
    Suso.

  3. Fattie says:

    Hey dude, this is a great idea. Hope you sell plenty of them.

    One suggestion, why so cheap?

    To hire one programmer at a game company grosses about 17 to 20 thousand per month (including salary, taxes, benefits, office space, equipment, overheads, support and all the other many costs).

    A game company would assign say nine man-months (3 guys for 2 or 3 months) to look in to a job like this.

    The product you’re selling, the source is worth “thousands or tens of thousands” it’s a shame to sell it so cheaply.

    Another way to look at it – say you’re a app store programmer working independently and you want to do a line-drawing app. That person could spend say 2 or 3 months to get to this stage, or, just buy your product. If the person simply chose to buy your product, they could instead do any old boring programming freelance or contract for TWO OR THREE MONTHS, earning 20 to 40 thousand bucks in that time. (Basically a QUARTER OF A YEAR of work.) Thus, your product puts them 20 or 40 thousand ahead.

    (Don’t even mention if the programmer is still on a learning curve, where the time-price would be vast.)

    So, really I’m just complaining that the price is so low! All the best,

    • I had the price at $299 for two weeks and did not sell a single copy during that time. As far as I can tell, I sell only to Indies and very small companies. What you say is only true for some bigger companies who happen to think that way, and unfortunately not all of them think like that. And 17-20 thousand is very high as the running cost for a programmer. It’s more like 7-10 thousand (USD). Anyway, with other like-minded products developers also compare and will find that my Starterkit is more towards the lower end of the pricing range, which currently spans from $99 to $349. So the current price works for me, and for my customers.

  4. Ali says:

    Dear Steffen,

    Thanks for your helpful website.
    I don’t want to do anything with your source, I would just play with it and try to learn how did you implement it.
    I don’t want public it just for my knowledge propose.
    Anyway if you think you can give it to me with very very small amount please email and let me know.

    P.S. I don’t want to pay that amount and after 30 days I request you to refund the money. B/c I think 30 days is enough to learn!

    Sincerely,

    –Ali

    • Tom Schulz says:

      I think what you’re asking here is like going into a restaurant and asking them nicely if they will let you smell the entree, and then saying that at least you’re not ordering it, smelling it, and demanding a refund. Respect yourself.

      • Christine says:

        Seriously Ali that is bad. It’s like paying for a course, learning, then asking for money back. That isn’t fair at all. I hope others would never do the same.

  5. Craig says:

    Hi Steffen, I’m on the vergenofmpurchsing this StarterKit but was curious asmto whether or not in includes support for the retina display…I don’t see any mention of it anywhere. Thanks.

  6. Jad says:

    Would just like to add just purchased linedrawing at the discount price main reason is I am trying to learn cocos2d and this will give me a good insight into how it all ties together. The discount price makes it worth while to me not sure I would have spent double. Have your book on preorder so hopefully will have the tools now to get me fired up.

    One question what extra would I have got with the cd?

    Keep up the good work you site and words are helping people like me who have apps published but would like to get into game type apps

    Thank you

    • Thanks for sharing your thoughts! The CD option is just a service from Plimus which allows you to get a copy of the download on a CD. To be honest, only one in 50 customers take that option. These days it’s a bit moot because burning a CD/DVD has become so ubiquitous.

  7. nickthedude says:

    hey, does the code include game menus and such?

  8. JAD says:

    The source is very easy to follow have created a couple of variants already and starting to add some functionality to the code ie blockers, path etc as all good apps the real problem is ideas. I will probably be submitting one shortly to the store. nickthedude your right about menus and such they do need adding to a game so currently trying to work out the best way to add a start menu and optional game screens the easy way. But I really found this useful, just hope the book is as good. I down loaded the source from the book and have compiled it up I reckon some of the ideas from there will get incoperated in the app. WWould just like to say thanks to Steffen.

  9. Grimlog says:

    I bought your book while it was in beta awhile back from apress during the special intro price. I have waited for it to be done and I am glad it is. It is very good and I am a newbie dillness to obj c, but I get it.

    But I must say I maybe “getting” it is because I also bought the iphone gamekit in 24 hrs, I bougth both svg and sapus. I think the competition amongst you developer guys just means better products for us. Ricardo is a great guy, I talk to him on email and he really cares about cocos2d and his customers.

    What you all are doing is completely different games, styles, and teaching ability. I do not think you are hurting Ricardo at all, I think you may make him better by introducing competition. There is plenty of $$ to go around.

  10. Grimlog says:

    BTW, you are in no way infringing on anything. It is just the liberal free will market of the internet. Find a need and fill it. They will buy it. Simple fair.

  11. steve says:

    Hi,
    Was wondering if it is possible to purchase the book yet?

    Also, I’ve written a form of SVG Parser that can be used in platform games using Box2D, I’m using it in my game, you basically use Inkscape to draw box’s around platforms for collisions and use lines for hills – the SVG file is then parsed and the Box2D bodies created dynamically, wondered if this could be of interest to anybody?

    Regards,
    Steve – contact me steg90@yahoo.co.uk

  12. Muzammil says:

    Hi Steffen,

    I am a iPhone/iPad. I like to purchase your Line-Drawing Game Starterkit. Currently i am working on some project in which i need to draw some smooth lines and curves with arrow as flight control. And i don’t have much more time to do R&D in this. So i am looking for some available library.

    But before purchasing your code i just want to make sure is this will be helpful for me or not. Can you show me some demo app or demo lib ?

    You may also send your reply at my mail id: muz.iphonedev@gmail.com we will further discuss there.

    Please reply asap.

    Thanks
    Muzammil

  13. […] browsing his blog i stumbled upon his “Line-Drawing Game Starter Kit”, a cocos2D based prototype he wrote for flight control like games. Price tag: ~119$. According to […]

  14. tom says:

    I downloaded the app… theres no sound however…

  15. Paul Menard says:

    Steffen,

    I’m enjoying your Apress book and found you had other item for sale on your website. Good deal.

    But noticed the line draw product is based on the older version of cocos2d and and older version of Xcode. So before I purchase wondering if there plans to update or any known compatibility issues?

    • The latest stable Cocos2D is still v0.99.5. The v1.0.0 is an unstable release which I decided not to support in general because they used to be updated too frequently, but now everyone is using the unstable releases because the stable is simply quite old. The changes to v1.0 are mostly cosmetic in nature (renamed classes), I outlined the necessary changes in this blog post.

      I expect the v1.0 to come out sometime soon, I’ll update the code when that happens and test it with Xcode 4 obviously. Eventually I’ll migrate the code to Kobold2D.

      There are no Xcode 4 issues that I know of.
