Unreal Engine 4.X By Example

### Unreal Engine 4.X By Example #### Introduction to Unreal Engine 4 Unreal Engine 4 (UE4) is a powerful game development platform that provides developers with the tools they need to create high-quality games and interactive experiences. This section will delve into the key aspects of UE4 as outlined in the book "Unreal Engine 4.X By Example." ##### Navigating this Book The book is structured to guide readers through the process of creating a game using UE4, starting from installation to building complex game mechanics. It covers everything from basic concepts to advanced features. ##### Game Projects You Say? The book focuses on practical examples through game projects, which are designed to be engaging and informative. These projects serve as a stepping stone for learning various aspects of game development, such as scripting, animation, and level design. ##### Installing Unreal Engine 4 To get started with UE4, you need to download and install the engine from the official Epic Games website. The installation process is straightforward and involves downloading the Epic Games Launcher, which manages the installation of the engine. ##### Creating Your First Project Once UE4 is installed, you can create your first project by selecting the "Create New Project" option in the Epic Games Launcher. You can choose from various templates depending on the type of game you want to create. For beginners, it's recommended to start with a simple template like the "First Person" or "Third Person" template. ##### Navigating the Unreal Engine UI UE4 has a comprehensive user interface that includes several important components: - **Content Browser**: This is where all assets are stored and managed. - **Viewport**: The main area where you can see and manipulate your scene. - **Outliner**: Lists all the actors in the current level. - **Details Panel**: Provides properties and settings for selected objects. ##### Creating a Basic Actor In UE4, an actor is the fundamental unit of a game world. Actors can represent anything from static meshes to characters. To create a basic actor, you can use the "Add New Actor" button in the toolbar or right-click in the viewport and select "Add Actor." Actors can be customized using the Details panel. ##### Objects, Actors, Pawns, and Characters - **Objects**: Base class for all other classes in UE4. - **Actors**: Objects that exist in a level and have a location and rotation. - **Pawns**: Actors controlled by players or AI. - **Characters**: Subclass of Pawn designed specifically for humanoids. ##### Adding Components to Your Actor Components are modular parts that can be added to actors to give them specific functionalities. For example, adding a Static Mesh Component to an actor gives it a visual representation. Other components include: - **Static Mesh Component**: Used for displaying 3D models. - **Point Light Component**: Emits light from a single point. - **Box Collision Component**: Adds collision detection to an actor. ##### 3D Transformation and Axis Understanding how to manipulate actors in 3D space is crucial. UE4 uses a coordinate system where X is the forward axis, Y is the right axis, and Z is the up axis. Transformations include: - **Translation**: Moving an actor along one or more axes. - **Rotation**: Rotating an actor around one or more axes. - **Scaling**: Changing the size of an actor. ##### Adding the Unreal Factor This refers to the process of making your game look and feel more realistic or immersive by adding details like lighting, materials, and animations. ##### Pre-Built Projects as a Learning Resource The book includes pre-built projects that serve as examples and can be used as a reference for learning specific features or techniques. These projects provide a starting point for further customization and experimentation. --- ### Blueprints and Barrels – Your First Game This chapter focuses on creating a simple game using Blueprints, UE4's visual scripting system. ##### Creating Your First Blueprint Blueprints are a powerful tool for non-programmers to create complex game logic without writing code. They use a node-based interface for defining behavior. - **The Blueprint Window**: This is where you design your Blueprint. It includes a graph editor and a list of available nodes. - **Working with Blueprints**: Involves connecting nodes to create functions and sequences of actions. - **Blueprint Elements**: - **Graphs**: Represent different types of logic flows. - **Functions**: Reusable pieces of logic. - **Macros**: Similar to functions but cannot be called directly. - **Variables**: Store data within a Blueprint. - **Event Dispatchers**: Trigger events when certain conditions are met. ##### Modifying the Hello Sphere Blueprint This involves modifying a simple sphere actor to add basic interactivity. - **Working with Blueprint Graphs**: Connect nodes to create interactions. - **Compiling Blueprints**: Required after making changes to ensure they function correctly. - **Using Blueprint Variables**: Store and manipulate data within Blueprints. - **Utilizing the Blueprint Palette**: A collection of commonly used nodes. - **Blueprint Meta-data and String Manipulation**: Add metadata to Blueprints and manipulate strings. ##### Creating the Barrel Hopper Project! This project involves creating a character that can hop between barrels in a level. - **Creating Our Character**: Designing a character actor and adding necessary components. - **Bringing Our Character to Life**: Animating the character and setting up movement. - **Giving Our Character a Mesh**: Assigning a 3D model to the character. - **Creating the Character’s Camera**: Setting up a camera to follow the character. - **Game Modes and How to Make Them**: Defining the rules of the game. - **Creating and Receiving Input Events**: Allowing player input to control the character. - **Tweaking the Character Movement Component**: Customizing character movement. ##### Building the Level! This involves designing and constructing the game environment. - **Camera Tips and Tricks**: Positioning and animating cameras. - **Camera Settings**: Adjusting camera parameters. - **Controlling the Camera**: Implementing camera controls. - **Creating the Level**: Using the Content Browser and tools. - **Blocking Geometry**: Roughly shaping the level. - **Geometry Brushes and How to Use Them**: Tools for sculpting terrain. - **Placing the Geometry**: Adding and manipulating shapes. - **Converting a Geometry Brush to a Static Mesh**: Optimizing performance. - **Applying Materials to Geometry Brushes**: Texturing surfaces. ##### Getting Our Barrels Rolling This involves implementing physics and spawning mechanics for the barrels. - **Applying Physics to Objects**: Making objects behave realistically. - **Barrel Spawners and Blueprint Timers**: Controlling when and where barrels appear. - **Creating Blueprint Variables**: Storing and manipulating data. - **Event Tick**: Updating values every frame. - **Branch Nodes**: Conditional logic. - **Trigger Volumes and Destroying Actors**: Detecting when actors should be removed. - **Debugging Our Blueprints**: Identifying and fixing issues. - **Masking Our Destruction with Particles**: Visual effects for destruction. - **Respawning the Player**: Bringing the player back after death. - **Delay Nodes**: Timing delays. - **Player Controllers**: Managing player-related logic. - **Hit Events**: Detecting collisions and impacts. #### Summary This chapter covers the basics of creating a game using UE4 and Blueprints. It demonstrates how to create a character, build a level, and implement game mechanics, providing a solid foundation for more advanced topics covered in later chapters.
