AActor::EnableInput

function Engine Blueprint Since 4.0

#include "GameFramework/Actor.h"

Access: public Specifiers: UFUNCTIONBlueprintCallablevirtual

Description

Pushes this actor onto the input stack of the given PlayerController so it can receive and respond to input events. Creates the InputComponent if it does not already exist.

Caveats & Gotchas

• This does not automatically bind any actions — after calling EnableInput you still need to set up bindings on InputComponent. The function only makes the actor eligible to receive input.
• Input priority on the stack matters: actors pushed later receive input first. If you have multiple actors receiving input, be aware that one consuming an event will block actors lower in the stack.
