Overlap Events in Unreal Engine - C++ Code Explanation

Sure! Here is an example of how to handle overlap events in Unreal Engine using C++:

// Step 1: Include the necessary headers
#include "MyActor.h"
#include "Components/BoxComponent.h"

// Step 2: Create a function to handle the overlap event
void AMyActor::HandleOverlap(UPrimitiveComponent OverlappedComponent, AActor OtherActor,
    UPrimitiveComponent* OtherComp, int32 OtherBodyIndex, bool bFromSweep, const FHitResult& SweepResult)
{
    // Step 3: Implement the desired behavior when overlap occurs
    // For example, print a message to the screen
    GEngine->AddOnScreenDebugMessage(-1, 5.f, FColor::Red, TEXT("Overlap occurred!"));
}

// Step 4: Attach a collision component to your actor
AMyActor::AMyActor()
{
    // Create and attach a box collision component
    BoxComponent = CreateDefaultSubobject<UBoxComponent>(TEXT("BoxComponent"));
    RootComponent = BoxComponent;

    // Bind the overlap event to the HandleOverlap function
    BoxComponent->OnComponentBeginOverlap.AddDynamic(this, &AMyActor::HandleOverlap);
}

// Step 5: Clean up
AMyActor::~AMyActor()
{
    // Remove the dynamic binding to avoid memory leaks
    BoxComponent->OnComponentBeginOverlap.RemoveDynamic(this, &AMyActor::HandleOverlap);
}
