Creating Functional Tests with the Automation System
In this post I’m going to show you how to create Functional Tests with the Automation System that comes with the latest version of Unreal Engine 4. With functional tests, we can simulate a user’s behavior (to some extent) and verify that everything is working properly.
In this post we’re going to create a simple script……
Creating Unit Tests with the Automation System
In this post I’m going to show you how to use Unreal’s Automation System in order to create unit tests for your code. Unit tests are tests written by developers in order to test various aspects of their code and identify bugs or other unintended behavior before it happens.
In order to test out the Automation……
Profiling Code Blocks
In this post I’m going to show you how you can profile your code blocks in order to identify potential issues and make your game run smoother!
In order expose your code’s performance in the Unreal Engine profiler tool you really need two things:
A stat group, which is the “category” of the code you’re profiling in……
Consuming lib and dll files
In this post I’m going to show you how you can consume .lib and .dll files in your ue4 project. In case you don’t have a library or a dll file hanging around I’m going to show you how to create one and provide some example files that I have created for this post.

Then, the controller of the AI pawn will move the……
Extending the details panel
In this post I’m going to show you how to extend the details panel inside the engine to expose more customised behavior for the systems that you might have built for your designers. Before I dive any further into the code, here’s the end result:
…
Creating a File Picker
In this post we’re going to see how to create a basic File Picker inside Unreal Engine. We’re going to use the built-in tools that the engine provides and read a text file.
Adding the required Dependencies
