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 both iPhone & iPad versions!
The Starterkit compiles to both iPhone and iPad devices natively using the same code. 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.
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

Feature List:
- clearly seperated and well-structured GameScene code design with a minimum of dependencies
- easy to add new objects and extend object parameters
- assertive coding style to help catch coding errors early on
- touch object & draw a path for it (whether it’s already following a path or not)
- path drawing ends when path is drawn over appropriate target location (eg airstrip for airplanes, respecting angle of approach)
- path drawing ends when arbitrary point limit is exceeded (to avoid slowdowns)
- path is drawn when dragged with thick transparent line style like Harbor Master, without glitches
- path is split into equal length pieces no matter how quickly user moves finger
- objects spawn outside screen, locations can be re-defined and extended
- objects display incoming warning marker at screen border
- objects display collision warning when any two of them are getting too close
- objects follow path to end – then fade out and increase score or continue moving
- objects always rotate in movement direction
- objects bounce back at screen borders
- motivational Labels for successful landings, precached
- Score and HighScore Labels
- HighScore saved to disk between play sessions
- supports both Landscape orientations with autoflip
- loads correct resource files depending on Target (iPhone or iPad)
- proper Pause handling for incoming calls, SMS
- Many generally useful Math Helper functions included
- Lots of comments explaining rationale and giving tips for improvement
- Fully documented
- Uses the professional Xcode Project from my Tutorial (Feature List)
- includes both iPhone/iPod Touch and iPad versions using seperate Targets, same codebase
- uses and includes cocos2d v1.0.1
- compatible with iOS 3.x, 4.x and 5.x
- compatible with Xcode 3.2 and Xcode 4.x
- easy setup, just unzip and use – no Xcode project setup required

Can we use the existing project and revise it to build a new game. Or must we start a new (empty template) project and rewrite the code. I don’t mind rewriting, I just want to know. I tried to replace some images but the project compiles with errors. Especially the MainMenu class.
You can base your work on the existing project. You don’t have to start a new project.

just purchased the Kit…its like buying the book, but more exciting…Steffen where did You learn to code in such a “clean” way…I am shocked about my style….
Hi Steffen.
I’m novice regarding Cocos2D and I’m learning it now from your book which I bought when it was alpha version and while searching the web I have found this kit.
I have few questions regarding kit and classes in it:
- I need to draw lines that are going to be represented as objects on the screen, so they are going to stay on the screen. Is that possible with this kit and Path classes?
- Is it hard to implement collision detection on lines/paths with this kit? For example if user draw line over the another one that already exists on the screen line should be invalid and deleted with invalid move message?
Thanks for answers
Kind regards
Amar
There’s a path class that draws itself. So if you create an instance of the Path class, provide some points, it will be visible for as long as the instance remains on screen.
Line-Intersection is a common mathematical problem. If you google it you’ll find explanations and also some code samples and explanations. The Starterkit doesn’t have this test built in but since you have all the points of each path you only need to test each line segment of a path with the segments of another path using a line intersection test utility function.
That gave me an idea though. I think such utility functions for collision tests should be part of Kobold2D. If you think so too please vote for that feature.
Thank you for the answers. I’m definitely buying this kit.
Thanks a lot!
Hello, good afternoon.
There is a possibility to be creating pre-defined paths to the object then?
Yes, you can manually create an instance of the Path class and add custom points to the Path.
Hi, is it also possible to draw a path between objects and both are moving on the path until they collide?
Sure, but one object would have to traverse the Path backwards which would require additional code (should be trivial). Or make a copy of the Path and reverse the path points in the list, might be even easier.
Will there be a Christmas-promo?
Hi, I bought it and I’m quite impressed about the clean code and having a complete game. Since my goal is not to create a clone of the kit-game I would like to see some simple examples. Esp. an example showing how to move some animated sprites (create from plist using TexturePacker) and create a path.
I do not understand how I can add an animated sprite like base on
[[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile:@”rolling.plist”];
rollingSanta = [CCSprite spriteWithSpriteFrameName:@"rollingSanta0001.png"];
Thanks, Uwe

i just purched your line drawing game code, i will look at
cheer that is’ half of value..
Thanks and happy New Year here.
Hi, in the source I found this remark in MovingObject.m:
// stopAllActions seems to be the only thing that can stop a sequence from calling the callfunc it contains
// the downside is that moving objects can’t run any other actions while following a path
Does this mean that a MovingObject cannot be an animated sprite but only one static frame?
Thanks,
Uwe
I believe this cocos2d bug has been fixed, so stopping the action by tag should work. Reminds me to test this again. Either way you can still animate the object by getting the animation action before stopping all actions, then re-running the animation object after stopping so that the animation continues.
Thanks! Will there be more examples then based on your classes? I think of simple things like putting one CCSprite on the screen and move it using a path.
Not a complex and complete game-source.
Best,
Uwe
No it’s just the entire game but the individual parts are fairly easy to extract. There’s a path class that holds all the path points and then each object has two methods which control moving along the path, and rotating in the direction of the path.
