Unreal Engine Simple Projectile — Unreal-engine Code
Blueprint projectile with optional C++ movement logic using ProjectileMovementComponent.
// Blueprint: Projectile Actor
// Add Sphere Collision + Projectile Movement
// On Hit -> Destroy
/* C++ Example: Projectile.cpp */
#include "Projectile.h"
#include "GameFramework/ProjectileMovementComponent.h"
AProjectile::AProjectile() {
ProjectileMovement = CreateDefaultSubobject<UProjectileMovementComponent>(TEXT("ProjectileMovement"));
ProjectileMovement->InitialSpeed = 1000.f;
ProjectileMovement->MaxSpeed = 1000.f;
}
void AProjectile::NotifyHit(UPrimitiveComponent* MyComp, AActor* Other, UPrimitiveComponent* OtherComp, FVector NormalImpulse, const FHitResult& Hit) {
Destroy();
}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.
Primary Use Cases
