UE4 UFUNCTION Keywords Explained

In this post I will be covering the common keywords used with the UFUNCTION macro in Unreal Engine 4. Each of the keywords covered include a practical code sample and a look at how it compiles into Blueprint nodes.  I left out the networking specific keywords as they deserve a separate post on networking in Unreal […]

Custom SoundNode for Multiplayer in UE4

Ever since the first public release of Unreal Engine 4 I’ve been using a neat little custom SoundNode that makes life easier for audio designers when dealing with mono/stereo sound playback in (networked) games. The node originates from the official ShooterGame sample content available on the Learn-tab of the UE4 launcher. I’ve used it in […]

Building Shooter AI in Unreal Engine 4

You may have seen my earlier blog post about a 4-player coop game I’m working on inside of Unreal Engine 4. It had the first iteration on ranged combat AI and they proved to be a formidable enemy. The problem was they got stale pretty quick, with simplistic and predictable behaviors. The new AI improvements […]

Using C++ Timers in Unreal Engine 4

With a recent change in the C++ API, the FTimerHandle was introduced to gameplay timers. At the time of writing the documentation for this is not up-to-date, so I thought I should share some information on how to work with timers in C++ with this mini tutorial. For practical examples on timers check out my C++ […]
