Unreal Engine Object Spawner — Unreal-engine Code
Spawns actors dynamically in the level when pressing a key, demonstrated via Blueprint and C++.
// Blueprint: ObjectSpawner Actor
// Add Input Action (SpawnObject)
// Use SpawnActor node to create Blueprint Class
/* C++ Example: ObjectSpawner.cpp */
#include "ObjectSpawner.h"
#include "Kismet/GameplayStatics.h"
void AObjectSpawner::SpawnItem() {
if (SpawnClass) {
FVector Location = GetActorLocation() + FVector(0,0,100);
GetWorld()->SpawnActor<AActor>(SpawnClass, Location, FRotator::ZeroRotator);
}
}Unreal-engine Language Guide
Unreal Engine is a high-end, real-time 3D creation platform developed by Epic Games, used for building AAA games, cinematic experiences, virtual production, simulations, architecture visualization, and interactive applications with photorealistic graphics.
