1.準備碰撞體基類

#pragma once#include "CoreMinimal.h" #include "GameFramework/Actor.h" #include "HitCollision.generated.h"/*** */UCLASS(BlueprintType, Blueprintable) class SIMPLECOMBAT_API AHitCollision : public AActor {GENERATED_BODY()UPROPERTY(VisibleAnywhere, BlueprintReadOnly, Category = "HitCollision", meta = (AllowPrivateAccess = "true"))class USceneComponent* HitCollisionRootComponent; public:AHitCollision(const FObjectInitializer& ObjectInitializer);virtual UPrimitiveComponent* GetHitDamage();protected:// Called when the game starts or when spawnedvirtual void BeginPlay() override;// Called every framevirtual void Tick(float DeltaTime) override; };

進行實現

#include "Hit/Core/HitCollision.h"AHitCollision::AHitCollision(const FObjectInitializer& ObjectInitializer) :Super(ObjectInitializer) {//創建根組件HitCollisionRootComponent = CreateDefaultSubobject<USceneComponent>(TEXT("CollisionRootComponent"));RootComponent = HitCollisionRootComponent; }UPrimitiveComponent* AHitCollision::GetHitDamage() {return NULL; }void AHitCollision::BeginPlay() {Super::BeginPlay(); }void AHitCollision::Tick(float DeltaTime) {Super::Tick(DeltaTime); }

2.繼承至基類，創建盒體碰撞體

#pragma once#include "CoreMinimal.h" #include "Hit/Core/HitCollision.h" #include "HitBox.generated.h"/*** */ UCLASS(BlueprintType, Blueprintable) class SIMPLECOMBAT_API AHitBoxCollision : public AHitCollision {GENERATED_BODY()UPROPERTY(VisibleAnywhere, BlueprintReadOnly, Category = "BaseAttrubute", meta = (AllowPrivateAccess = "true"))class UBoxComponent* HitDamage; public:AHitBoxCollision(const FObjectInitializer& ObjectInitializer);virtual UPrimitiveComponent* GetHitDamage();//設置盒子尺寸void SetBoxExtent(const FVector& InNewBoxExtent); protected:// Called when the game starts or when spawnedvirtual void BeginPlay() override;// Called every framevirtual void Tick(float DeltaTime) override; };

進行實現

#include "Hit/ComboSkillHitBox.h" #include "Components/BoxComponent.h"AHitBoxCollision::AHitBoxCollision(const FObjectInitializer& ObjectInitializer):Super(ObjectInitializer) {HitDamage = CreateDefaultSubobject<UBoxComponent>(TEXT("HitDamage"));HitDamage->SetupAttachment(RootComponent); }UPrimitiveComponent* AHitBoxCollision::GetHitDamage() {return HitDamage; }void AHitBoxCollision::SetBoxExtent(const FVector& InNewBoxExtent) {HitDamage->SetBoxExtent(InNewBoxExtent); }void AHitBoxCollision::BeginPlay() {Super::BeginPlay(); }void AHitBoxCollision::Tick(float DeltaTime) {Super::Tick(DeltaTime); }

3.繼承至基類，創建膠囊體碰撞體

#pragma once#include "CoreMinimal.h" #include "Hit/Core/HitCollision.h" #include "HitCapsule.generated.h" /*** */ UCLASS(BlueprintType, Blueprintable) class SIMPLECOMBAT_API AHitCapsuleCollision : public AHitCollision {GENERATED_BODY()UPROPERTY(VisibleAnywhere, BlueprintReadOnly, Category = "BaseAttrubute", meta = (AllowPrivateAccess = "true"))class UCapsuleComponent*HitDamage; public:AHitCapsuleCollision(const FObjectInitializer& ObjectInitializer);virtual UPrimitiveComponent* GetHitDamage();void SetCapsuleHalfHeight(float InNewCapsuleHalfHeight);void SetCapsuleRadius(float InNewCapsuleRadius); protected:// Called when the game starts or when spawnedvirtual void BeginPlay() override;// Called every framevirtual void Tick(float DeltaTime) override; };

進行實現

#include "Hit/ComboSkillHitCapsule.h" #include "Components/CapsuleComponent.h"AHitCapsuleCollision::AHitCapsuleCollision(const FObjectInitializer& ObjectInitializer) :Super(ObjectInitializer) {HitDamage = CreateDefaultSubobject<UCapsuleComponent>(TEXT("HitDamage"));HitDamage->SetupAttachment(RootComponent); }UPrimitiveComponent* AHitCapsuleCollision::GetHitDamage() {return HitDamage; }void AHitCapsuleCollision::SetCapsuleHalfHeight(float InNewCapsuleHalfHeight) {//設置膠囊體半高HitDamage->SetCapsuleHalfHeight(InNewCapsuleHalfHeight); }void AHitCapsuleCollision::SetCapsuleRadius(float InNewCapsuleRadius) {//設置膠囊體半徑HitDamage->SetCapsuleRadius(InNewCapsuleRadius); }void AHitCapsuleCollision::BeginPlay() {Super::BeginPlay(); }void AHitCapsuleCollision::Tick(float DeltaTime) {Super::Tick(DeltaTime); }

4.繼承至基類，創建球體碰撞體
