Enhanced Input in Unreal Engine 5 C++: Blueprint to C++ Cheatsheet
Unreal Engine 5's Enhanced Input system replaced the legacy axis and action mappings, and most tutorials still show it through Blueprints. This category maps each Enhanced Input Blueprint node to its real C++ equivalent so you can wire input directly in your ACharacter or APawn subclass.
You will find the C++ for adding an UInputMappingContext through UEnhancedInputLocalPlayerSubsystem, binding an UInputAction on UEnhancedInputComponent, reading values from FInputActionValue, and choosing the correct ETriggerEvent. Every snippet shows the header declaration and the implementation side by side.

Add Input Mapping Context
The Add Mapping Context Blueprint node maps toUEnhancedInputLocalPlayerSubsystem::AddMappingContext in C++. You grab the subsystem from the local player and register a UInputMappingContext with a priority value, usually in BeginPlay.View C++ equivalent →Bind Input Action
Binding an Input Action in C++ usesUEnhancedInputComponent::BindAction inside SetupPlayerInputComponent. You cast the input component to UEnhancedInputComponent and bind a UInputAction to a member function for a given ETriggerEvent.View C++ equivalent →Read Input Action Value
Reading an Input Action Value in C++ uses the templatedFInputActionValue::Get<T>(). You pick FVector2D, float, or bool to match the Input Action's Value Type, then use the result inside your bound handler.View C++ equivalent →Trigger Events (Started / Triggered / Completed)
ETriggerEvent selects when a bound function fires: Started on press, Triggered while held, and Completed on release. You bind the same UInputAction to different functions per event, which is the standard pattern for press-and-hold input like jumping.View C++ equivalent →
