I’m Philippe, a freelance in web development since 1998. I work with Jean-Yvon my web designer and we are located near Paris in France.
As a small organization, we always have to follow technological developments in order to keep and find customers.

For our first project, it seemed to be easier and shorter to develop a game for children (which needs less resources – no 3d or complex textures).
The AppStore brings us marketing opportunities with its 130 Millions of IOS devices (Android doesn’t seem mature yet).
One day, I saw my little daughter playing with my Iphone: she likes to scroll, loves animals sound and photo, so I imagine making a game with left/right scroll (by sliding) for finding animals.
I always loved Playmobil©, so I liked the idea to create landscape and place items on it.
But how to make money with this concept?
We have chosen Cocos2d framework to develop our game (and to learn objective-c !) because:
- A lot of games use it (so it is mature)
- The community is very active
- A lot of tutorials and books are available.
- No need to learn openGL.
- It’s free and open source
It was our first IOS project: we had all to learn (objective-c, cocos2d, IOS sdk, device capacities, xcode…). We planned to do a simple game just to learn and test the AppStore.
But finally, we created a real game with a lot of graphical resources.
October 18 (week 42): I tell my web designer about my idea: he loves videogame, so no need to convince him, create a game (even for children) can only be fun! So we started to work on the concept and I tried to create a prototype with cocos2d during the first 2 weeks.
For each world, Jean-Yvon had to:
- Create the landscape (with 2 layers for parallax effect). He (re)discovered hand drawing/painting with a Wacom Bamboo tablet and he is talented! Each landscape is composed of three environments (like desert/savanna/jungle) for a total size of 9000*640 px (HD).
In this post, I will point out some techniques or difficulties I had to deal with:
- Scrolling: I used a personalized CCScrollView with Parralax effect. Scroll view had to be resizable (to create 3 distinct areas: left/middle/right). It had to use bounce or not, swipe effect (with decreased speed) or not (for camera mode). Gesture recognition was a problem with children's small and imprecise finger: they need to scroll and touch animals. So i had to deal with the speed of gesture and speed of scroll (if the scroll is near stopping, touching an animal is treated).
