Making a cross-platform game in two weeks

In today’s post I would like to share with you my experience working on my first cross-platform game. Although it is intended to be available for Windows Phone, iOS and Android, currently I’m focused on the Windows Phone version.

The game is called Muster my Monsters (MmM). It is a two-player fighting monsters action game. It is a casual game, so game mechanics need to be simple and art appealing to most of people. Here you have a gameplay video.

App prototyping with Keynote

Prototyping is a critical developing phase. During prototyping you may find design problems on your app that, if not detected early, would probably make you and your team waste an important amount of time.

There are a lot of techniques and tools to create prototypes. You can prototype on paper while brainstorming and use sophisticated tools later to create visually appealing prototypes.

However, I decided to use Keynote for prototyping my last client app Aduho Mirror. In today’s post I would like to share my reasons and experience.

FacebookScorer – Post highscores to user’s Facebook Wall

Today’s post is an update for an old article about posting high scores to Facebook Wall. Some users have reported some issues about this class. There were some problems with the state control when authorization was needed.

Today I will like to post a new version of the class that solves these issues. The project is now called FacebookScorer and you can find it on GitHub.

The mobile cross-platform development headache

The lasts weeks I have been trying and playing with different frameworks, methodologies and alternatives to mobile cross-platform development. In today’s post I would like to share with you my conclusions and… headaches.

So, you know, by definition cross-platform development is never an easy issue. Every platform is very different from each other just because it needs to differentiate from the competitors. So you, as a cross-platform developer, have to deal with it. Period.

Time distribution. One year later

About one year ago I wrote an article entitled “Time distribution on game development“. On this article you can read about what tasks I was working on when developing New Sokoban and how they were distributed on time. That post was written a few days before the approval of the game.

A year has gone since then and a lot of things have happened and changed. In today’s post I would like to present a new chart revealing important differences on time distribution on my everyday work. After that, I will try to get some useful conclusions.

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.

A Twitter reusable class. iOS 5.0 ready with iOS 4.x retrocompatibility

Today I would like to share with you a little but useful class to post highscores  to Twitter on your games. This tutorial is the perfect companion for the Facebook one I wrote some weeks ago. It basically adds a new abstraction layer to the MGTwitterEngine from Matt Gemmel and the OAuth Twitter Engine from Ben Gottlieb providing the needed UI to send tweets to the user timeline.

The tutorial also shows how to figure out the iOS version and use the Apple’s Twitter API for iOS 5 if available.

You can download the entire project at the end of the article.

An update management handy class

Today I would like to share with you a little piece of code that I find very handy. A class that helps you managing “updates”. I use it in my apps that work with cached data. You could encounter the situation where you need to develop an app that queries a web service to obtain the data to be shown on the device.

However, sometimes the information you need to access doesn’t change so often and it is not necessary to bother the user with a loading message only to end up showing the same information than 2 minutes before. If being up to date accurately is not critical for your app, the code I’m going to show may help you.

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.
