Guest post: The Making of Pigeons Attack with Cell SDK

Pigeons Attack was born as a sample to show how the accelerometer API works. You move forward and backward –tilting your phone- your just washed car in order to avoid pigeons get it dirty. Once the semaphore becomes green, leave quickly the scene to check how many impacts you had. The less you have the better.

Within the following sections you will be guided through the development process, starting from a new Cell SDK project.

Game Theory Applied: the puzzle of designing a puzzle game

Today’s post is going to be the fourth in the series “Game Theory Applied”. You have the previous ones here:

Today I would like to talk about the tricky concepts around puzzles and puzzle-based games like New Sokoban. Puzzles are often considered to not be games at all. This means that designing a video-game entirely based on puzzles implies some issues that need to be addressed to minimize the inherent problems that puzzles have and maximize their benefits. We will see it applied to New Sokoban, a puzzle-solving game.

Game Theory Applied: Endogenous Value

Today’s article is the third one in the series “Game Theory Applied”. You have the previous two here:

In the previous two articles I talked about game design aspects that I think that were well addressed in New Sokoban. However, today I’m going to talk about a very difficult and tricky topic that should be better applied to New Sokoban: endogenous value in games.

Developing tools for creating a game

Some months ago I wrote an article on this blog titled “Tools for creating a game“. On that article I talked about the tools I used to develop my first iOS game New Sokoban. The message of that article was summarized with this mental note:

Mental note: always use existing tools. If there is a tool that barely fits your needs use it. You will be amazed about how quickly you adapt yourself to that tool and how your productivity increases.

However, currently I’m working on a new game that needed a very specific and game dependent developing tool. So, unfortunately, I spent about two weeks developing, testing and refining a development tool for my new game. In today’s article I’m going to share the experience.

A Facebook reusable class

In today’s post I’m going to share a piece of code that allows your games to easily connect to Facebook. It is a singleton class designed to be reusable, very simple to use and with only one task in mind: post new high scores on Facebook. You can find the example project source code at the end of the article.

The aim of this post is not to teach you about how to use the Facebook API to connect your iPhone games to Facebook. There are a lot of articles covering this topic and the official Facebook developers site. In this tutorial I would like to put the emphasis on the reusable and simplicity to use aspects. It is very easy to integrate in your projects the piece of code I’m going to show you.

From lone wolf to pack member

In today’s post I’m going to explain a little bit how my routine as an indie dev has changed in the last few weeks. I have experienced a really big change since New Sokoban was presented and released. I have gone from the lone wolf indie dev style to an intensive collaborative working style. And only in 2 months!

Gamelab 2011. Trying to avoid the unavoidable

From June 29 to July 1 has been celebrated in Barcelona (Spain) Gamelab 2011: the international videogames conference. I have been there the whole three days attending almost all the conferences and walking around the playing area. So, I have seen and lived probably the 95% of this Gamelab 2011. In today’s post I’m going to talk about my vision of the conference and the benefits I got from it.

Modal view controllers in cocos2d

Today’s post is going to be a tutorial-style one. One of the (few) annoying things of cocos2d is the fact that it is very unrelated to UIKit and the Model View Controller paradigm of Apple’s views a view controllers. This is a problem when you need to show, for example, a view controller modally to send an e-mail or show Game Center leaderboards and achievements.

In this tutorial I am going to describe the technique I use to connect with “Apple’s layer” from cocos2d in an easy, modular, reusable way. You will find the project source code used on this tutorial at the end of this post.

New Sokoban postmortem

Today’s post will be a classical one: postmortem of New Sokoban. New Sokoban was officially launched around a month ago and I think that it is enough time to write this post. Basically because I think that things are not going to change a lot in the future concerning New Sokoban. So, here you have what went right and what went wrong.

Synthesize: first iOS dev event in Málaga, Spain – My conclusion

Some time since the last post. I have been a little busy the last two weeks but today I’m back :) In today’s post I would like to share my personal conclusion about Synthesize, the first iOS dev meeting in Málaga, Spain, where I was invited to do a little talk. As you may expect if you follow this blog, this is not going to be a regular report of the event. I’m going to share with you my thoughts about how the event affected me.
