UE4：C++动态添加UStaticMeshComponent

1. 构造函数内添加

xxActor::xxActor()

{

//tank mesh

static ConstructorHelpers::FObjectFinder TankStaticMesh(TEXT(“/Game/Meshs/TwinStick/TwinStickUFO.TwinStickUFO”));

TankMesh = CreateDefaultSubobject(TEXT(“TankMesh”));

TankMesh->SetStaticMesh(TankStaticMesh.Object);

TankMesh->SetCollisionProfileName(UCollisionProfile::Pawn_ProfileName);

RootComponent = TankMesh;

}

2. 构造函数外添加（一定要添加RegisterComponent(),否则不会显示！）

bool AItemActor::InitComponent(FVector loc, FRotator rot)

{

bool bRtn = false;

//mesh

m_pMeshComponent = (UStaticMeshComponent*)NewObject(this, TEXT(“Mesh”));

m_pStaticMesh = CreateStaticMesh(m_ItemType);

if (m_pMeshComponent && m_pStaticMesh)

{

m_pMeshComponent->SetStaticMesh(m_pStaticMesh);

m_pMeshComponent->SetCollisionProfileName(UCollisionProfile::Pawn_ProfileName);

m_pMeshComponent->SetRelativeRotation(rot);

m_pMeshComponent->SetRelativeLocation(loc);

m_pMeshComponent->RegisterComponent();

m_pMeshComponent->OnComponentHit.AddDynamic(this, &AItemActor::OnHit);

RootComponent = m_pMeshComponent;
bRtn = true;
}

return bRtn;

}
