The time has come when I decided to change my default operating system from Windows to Linux (Ubuntu, to be more precise). There were few reasons I did it, but I’m not going to write about them right now. Right now I want to write about my search for the perfect C++ IDE for Linux.

There is a really old joke: “The best program to write C++ in Linux is the Linux itself”. It is well known that hardcore developers write code in Vim, build it by typing compiler’s commands by hand and use GDB in terminal to debug. But I’ve become lazy because of Windows and I really like to have slick and easy to use IDE such as Visual Studio, which… is not available on Linux, unfortunatelly.

I was looking for something similar to the Visual Studio which I’ve got used to. For me – a good IDE should let the programmer focus on programming not on fighting with building pipeline and tons of configurations. Having this in mind, from many IDEs available, I’ve selected few worth mentioning.

So I was talking at Digital Dragons 2018 about using Unreal Engine 4 to make a mobile game…

Another year – another Global Game Jam! It lasted 48h and this year topic was: “Transmission”.

Me and my colleague wanted to show the old way of message transmission – through the post pigeons, during the World War. We’ve also accepted the challange given to us by the other game jammer – to make a multiplayer game.

Long time ago I wrote an article about adding a multiplatform runtime module to the Unreal Engine 4. This day that article would be complately out of date. UE4 changes and the way the new stuff can be added to it changes too. First of all, I want to to be clear – this article will not cover 100% of the topic, because it’s simply too broad. This is rather a quick start into writing your own plugins, getting know the basics. This article will cover the following topics:

1. Creating a plugin
2. Building a plugin
3. Making a plugin that works differently,  depending on the platform
4. Using the plugin from C++
5. Using the plugin from Blueprints
6. Creating a plugin settings editable from the Editor
7. Calling asynchronous functions from Blueprints

When writing this article I was using the Unreal Engine 4.18.1.

For the lazy ones – here’s the github source code version.

So, with all of this in mind – let’s start!

It has already been 5 years since the Real Boxing franchise started to rock in the mobile world. Wow!

I personally wasn’t involved in this project from the very beginning, but still – I put some of my work and soul into it in updates of Real Boxing ( did you like tournaments? You’re welcome ;) ), but mostly into the RealBoxing 2 in general.

Both projects were technologically challenging and we’ve learned a lot from them. Using this knowledge we’re brewing some even more tasty stuff right now… But you will see it soon :)

For now – it is time to celebrate. Thanks for playing!

When writing a multiplayer game the question that arises more and more often is – “Should I bother about an IPv6?”

Short answer – YES! The IPv6 is no longer a tale from the future. The number of people using the newest version of the Internet Protocol increases really fast. Quick look at Google Statiscits and you will see, that numbers of requests to Google via IPv6 grows expotentially and when writing this post it reaches 18%

One of the reason why the IPv6 suddenly became a thing (except the main one – that we’re running out of addresses) is that Apple started rejecting apps that were not working with IPv6-only networks (Source). Shortly after that – Amazon announced support for IPv6 on their EC2 servers (Source). Currently – the biggest market that uses IPv6 is the mobile one, where number of devices might be even greater than the number of stationary computers.

So, how the networking code should be written to support the IPv6?

Yet, the another game jam! This time it was the 3rd edition of the Slavic Game Jam in Warsaw. Lots of Slavs, Nordics and bunch of other awesome people and games. Oh boy, there were a lot of games! About 86 if I remember correctly. You can check all of them here (the winner is Dot. if you wanna just play in the best one). But here… I’m gonna write some about my entry.

Another Game Jam has passed and oh boy, what a jam! This time it was organized by polish gamedev team Artifex Mundi in their office and a lot of one of the best developers did gather to make games within 42 hours. This game jam theme was: “Fail Fast”.

Do you know what is more annoying than a crash? A crash that you don’t know how to track down. You are praying for not being in a situation where no debugger is attached or there is no crash log. Sadly – this is a very common situation when you are working with the external engine, on a mobile device.

Android c++ crash logs are even more nasty, because of their binary format. In fact – they are minidumps, the same format the Microsoft is using for dumping Windows crash data. To encrypt the Android’s minidumps you need to do some voodoo with Google Breakpad.

Rvalue references are one of the biggest feature introduced to the c++11, but I found it rather difficult to understand and to find a usage for them. It was the issue which was very similar to the understanding c++ traits I had. Now, I’d like to write down all what I’ve learned, in order to remember it better and to share the way I understand it the best. This article is a very quick introduce to why we need rvalue references and why they are awesome!
