Unreal Engine Simple Door Interaction — Unreal-engine Code
Demonstrates interacting with a door actor using Blueprints and C++.
// Blueprint: Door Actor
// Add Static Mesh and Box Collision
// OnOverlap toggle door open animation
/* C++ Example: Door.cpp */
#include "Door.h"
#include "Components/StaticMeshComponent.h"
#include "Engine/Engine.h"
void ADoor::ToggleDoor() {
IsOpen = !IsOpen;
float TargetRotation = IsOpen ? 90.f : 0.f;
SetActorRotation(FRotator(0, TargetRotation, 0));
UE_LOG(LogTemp, Warning, TEXT("Door %s"), IsOpen ? TEXT("Opened") : TEXT("Closed"));
