Unreal Engine C++ API Reference | Unreal Engine 5.7 Documentation

Welcome to the Unreal Engine C++ API Reference! This is an automatically generated reference manual from the Unreal Engine Source code. For tutorials, walkthroughs and detailed guides to programming with Unreal, check out the online documentation for Programming in Unreal Engine.

Unreal Engine's systems and features are packaged in two ways:

Modules: The basic building block of Unreal Engine's software and architecture.
Plugins: Collections of modules and assets that you can enable or disable within the Editor on a per-project basis.

Explore all of Unreal Engine's modules, plugins, and their members here, organized hierarchically. You can use the search bar to find a known term, such as a class or function name.

You can also browse the modules and plugins below:
