SlippyFlippy 1.1: The Bug Hunt
Since my last post I got my first one-star review of SlippyFlippyPenguin. The Hard Mode bug did it. Someone else can’t start the game in hard mode. In my last entry, I set up a timer to fix what I thought is a user-related problem with the game. In the process, I found the real bug.…

From Apple to Raspberry Pi: Living without Storyboards and Interface Builder
In iOS, avoiding Interface Builder is nearly impossible. IB is old – as old as the Xcode SDK itself. Interface builder was one of the components of NextStep, and thus one of the reasons Steve Jobs got his old job back, who then developed NextStep into the platform for all Apple products. In more recent…

From Apple to Raspberry Pi: Windows Buttons and Widgets — on Pi!
I’ve explored much of the basic coding in Python, but I’ll need a good user interface for the projects I’m doing.

From Apple to Raspberry Pi: Using Strings
There are several ordered types in Python, one of the most common is the string. In Xcode, we defined a NSString this way: Objective-C has the @”…” indicators for a string. Python on the other hand can use the much easier “…” or ‘…’ The use of double or single quotes allows for the use…

From Apple to Raspberry Pi: Using Inheritance and Overrides
Object oriented languages have a concept called inhertance. A class can give its methods and properties to another class, which then replaces or expands the inherited class. We call the new class a subclass. When we replace a function or method we override the method or function. This allows the method or function of the…

The Slippy Flippy Dare: Making a Basic Obstacle
To make a game fun there must be a challenge. One of those challenges is some obstacle in your path or headed towards you. In both Flappy Bird and SlippyFlippyPenguin that obstacle is a large rectangle with a gap in it. Your job is to get through the gap. If you do, you score a …

From Apple to Raspberry Pi: Importing Classes and Disturbing Attributes.
I didn’t do as much As I thought I would today, as I was installing tightvnc on the Raspberry Pi. I then tried out acessing my RasPi on my Mac, Pc, and even my iPad mini. I wasn’t nuts enough t try it on my iPhone — yet. I did download the app though. …
