OnComponentHit除了“ CollisionCylinder”外不检测冲突

问题描述

我的弹丸类有这个问题。

即使将静态网格物体设置为BlockAllDynamic，它也不会与环境碰撞。生成怪异时，它确实设法移动了我的某些角色。

另一个问题是OnComponentHit不适用于我为角色设置的“胶囊碰撞”（“碰撞”设置为Pawn）。我从OnComponentHit得到响应的唯一时刻是它碰到了我从未创建的“ CollisionCylinder”。它比角色的所有组件都要小。我也在角色和射弹上启用了“模拟命中生成事件”。

#include "KnifeProjectile.h"
#include "Components/StaticmeshComponent.h"
#include "GameFramework/ProjectileMovementComponent.h"
#include "Kismet/GameplayStatics.h"

// Sets default values
AKnifeProjectile::AKnifeProjectile()
{
    // Set this actor to call Tick() every frame.  You can turn this off to improve performance if you don't need it.
    PrimaryActorTick.bCanEverTick = true;
    
    Root = CreateDefaultSubobject<USceneComponent>(TEXT("Root"));
    RootComponent = Root;

    ProjectileMesh = CreateDefaultSubobject<UStaticmeshComponent>(TEXT("Projectile Mesh"));
    ProjectileMesh->SetupAttachment(Root);

    ProjectileMovement = CreateDefaultSubobject<UProjectileMovementComponent>(TEXT("Projectile Movement"));
    ProjectileMovement->InitialSpeed = MovementSpeed;
    ProjectileMovement->MaxSpeed = MovementSpeed;

}

// Called when the game starts or when spawned
void AKnifeProjectile::BeginPlay()
{
    Super::BeginPlay();
    ProjectileMesh->OnComponentHit.AddDynamic(this,&AKnifeProjectile::OnHit);
    
}

void AKnifeProjectile::OnHit(UPrimitiveComponent* HitComp,AActor* OtherActor,UPrimitiveComponent* OtherComp,FVector normalImpulse,const FHitResult& Hit) 
{
    UE_LOG(LogTemp,Warning,TEXT("%s hit me"),*OtherComp->GetName());
}

// Called every frame
void AKnifeProjectile::Tick(float DeltaTime)
{
    Super::Tick(DeltaTime);
}
