This page explains terms commonly used in\u00a0Unreal Engine<\/strong>\u00a0. If you have wondered \u201cWhat is an\u00a0Actor<\/strong>\u00a0?\u201d or \u201cWhat is a\u00a0Component<\/strong>\u00a0?\u201d, this page answers those questions and more.<\/p>\n

After learning a term, explore the related topics at the end of its section.<\/p>\n

\n

This page uses programming concepts, especially\u00a0classes<\/strong>\u00a0and their\u00a0subclasses<\/strong>\u00a0. In C++, a\u00a0class<\/strong>\u00a0is an extensible code template containing variables and behavior. Its\u00a0subclasses<\/strong>\u00a0inherit some or all of a parent class's code and functionality.<\/p>\n<\/div>\n

\n

All C++ classes mentioned here are specific to Unreal Engine.<\/p>\n<\/div>\n

Project<\/h2>\n

The\u00a0Unreal Engine 5 project<\/strong>\u00a0contains all the game's content in folders on disk, such as\u00a0Blueprints<\/code>and\u00a0Materials<\/code>. Organize project folders as needed. The\u00a0Content Browser<\/strong>\u00a0in\u00a0Unreal Editor<\/strong>\u00a0shows the same directory structure as the\u00a0Project<\/code>folder on disk.<\/p>\n

Each project has an associated\u00a0.uproject<\/code>file. The\u00a0.uproject<\/code>file is used to create, open, or save a project. You can create multiple projects and work on them in parallel.<\/p>\n

For more information, see\u00a0Projects and Templates<\/a>\u00a0.<\/p>\n

Blueprint<\/h2>\n

The\u00a0Blueprint Visual Scripting<\/strong>\u00a0system provides complete gameplay scripting through a node-based interface in Unreal Editor. Like other scripting languages, it defines object-oriented classes or objects. In UE4, objects defined this way are commonly called \u201cBlueprints.\u201d<\/p>\n

For more information, see\u00a0Blueprints Visual Scripting<\/a>\u00a0.<\/p>\n

Object<\/h2>\n

Objects<\/strong>\u00a0are Unreal Engine's fundamental class, acting as building blocks with basic asset functionality. Almost everything in Unreal Engine inherits from an Object.<\/p>\n

In C++,\u00a0UObject<\/code>is the base class for Objects. It provides garbage collection, metadata (\u00a0UProperty<\/code>), exposing variables in Unreal Editor, and serialization for loading and saving.<\/p>\n
