Mastering Game Development with Unreal Engine 4 - Second Edition

Overview of this book

<p>To make a basic combat game from scratch, you will quickly override existing UE4 classes, and add and implement simple C++ functions while running and building them. These are all discussed as a short summary for new developers and as a quick refresher for experienced developers. Next, you will build a combat player character with expanded controls, create logic for a character, swap weapons, attack and move, bridge over scene changes and transitions, retain data between scenes, and manage the scene-change process. </p><p>You will then build an intelligent enemy AI and add physics based particles for weapon impacts. You will also get acquainted with cutting-edge features such as Volumetric Lightmaps for precomputed lighting, and Atmospheric and Volumetric Fog, to build advanced visuals in our ongoing GitHub project. </p><p>Moving on, you will explore the tools required to build an in-game cut-scene for a more professional gameplay experience and story direction. </p><p>Along the way, you will implement a solid game UI, including writing a full in-game load and save system that will enable players to resume their game from any point. You will also prepare, build, and work on VR and AR taking them from editor to real-world, building two new projects one in each of these brand new areas of UE4 and integrate classes from the main project into AR! </p><p>By the end of the book, you will have mastered all major UE features and will be able to bring self-imagined games to life through Unreal Engine 4.18+.</p>

Adding physics particles

Our goal here will have two parts: first, to add some sparks off of our projectile hits when they impact, but then to get those sparks bouncing around in the physics universe without utterly killing our framerate. One great piece of news is that UE4 supports GPU particles across all kinds of platforms for you, and in general this is where you want to be doing that kind of work. Should you find yourself in a game that is GPU-bound because of its complex visuals (or low-bar for platform hardware specifications), these kinds of things are often the first to go; but let's not worry about that now, let's make some pretty sparks first. 

Creating our initial emitter on projectile hit

So some...
