Kobold2D tutorial

Kobold2D is a extended and improved version of the popular Cocos2D game engine. It can be downloaded here.

This tutorial will make a simple parallax scroller. Nothing to fancy, only simple stuff. If you are new to programming you should get familiar with XCode and Objective C before trying to make a game. You can download this tutorial from here.
In this tutorial we will add speed when touching the screen witch will make the objects on screen to move, all clouds are independent from the user speed and are only affected by the wind speed. Factors that will have an impact on the objects speed is the friction of the ground, depth of the object from the user and the accumulated speed. Releasing the screen will stop adding speed and depending on friction and the retardation value the objects will decrease in speed until stopped.

Download and install Kobold2D and then run the Kobold2D Project Starter, choose the Empty-Project template.
For creating sprite sheets I will use Zwoptex.

In MainMenu there is only a sprite (start) and a background object. The sprite has dimming effect for added effects. Touching the start will change the MainMenu scene with the Scroller scene. One good thing to do when changing scenes is to clear textures and/or sprites that is not necessary in order to save memory. In this tutorial I use

[[CCSpriteFrameCache sharedSpriteFrameCache] removeSpriteFrames];
[[CCTextureCache sharedTextureCache] removeAllTextures];

since I only have small spritesheets and I don’t need the previous textures/sprites.

Simple iPhone app development tutorial

So you are new to Xcode and Objective-C, well don’t be scared, this tutorial will help you create a simple app. The app will not do anything special but it will implement stuff inorder to make simple stuff.

First we will establish what the app should do and what features we want to implement. Since this is a tutorial app the functionality of the app is not that important, we will focus more on the features. Lets make an app that changes the background picture of the app by dragging a selector on the thumb of the image. So we will implement animation and touch and drag.
