虛幻4 ue4 學習筆記pwan篇 1.1a 創建spherecomponent與boxcomponent 物體組件

#include "MyPawn.h"

#include "Runtime/Engine/Classes/Components/BoxComponent.h"//    UBoxComponent 引用
#include "Runtime/Engine/Classes/Components/SphereComponent.h"//    USphereComponent 引用
// Sets default values
AMyPawn::AMyPawn()
{
     // Set this pawn to call Tick() every frame.  You can turn this off to improve performance if you don't need it.
    PrimaryActorTick.bCanEverTick = true;

    //CreateDefaultSubobject ue4所有組件都是通過這個函數創建的
    //<USphereComponent>與<UBoxComponent> 告訴CreateDefaultSubobject要返回對象的類型是什么 
    //虛幻4所有對象都有CreateDefaultSubobject方法 

    UBoxComponent *BoxComponent = CreateDefaultSubobject<UBoxComponent>(TEXT("RootComponent2"));//創建一個正方體組件 RootCompont 是藍圖里面顯示的名稱 名稱隨意
    USphereComponent* SphereComponent = this->CreateDefaultSubobject<USphereComponent>(TEXT("RootComponent"));//創建一個圓球組件 RootCompont 是藍圖里面顯示的名稱 名稱隨意
    /*Vectoe是虛幻4中的向量類*/
}

// Called when the game starts or when spawned
void AMyPawn::BeginPlay()
{
    Super::BeginPlay();
    
}

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

// Called to bind functionality to input
void AMyPawn::SetupPlayerInputComponent(UInputComponent* PlayerInputComponent)
{
    Super::SetupPlayerInputComponent(PlayerInputComponent);

}

 

spherecomponent與boxcomponenet 是實現物理碰撞的必要組件
