#pragma onceUENUM(BlueprintType)
enum class EWeapoType : uint8
{EWT_AssaultRifle UMETA(DisplayName Assault Rifle),EWT_MAX UMETA(DisplayName DefaultMAX),
}; 3.4创建武器弹药数量捡起武器的声音 /*** 弹药数量 */UPROPERTY(EditAnywhere, ReplicatedUsing OnRep_Ammo)int32 Ammo;//弹药数量UFUNCTION()void OnRep_Ammo();UPROPERTY(EditAnywhere)int32 MagCapacity;//最大弹药数量void SpendRound();void SetHUDAmmo();UPROPERTY()class ABlasterCharacter* BlasterOwnerCharacter; // 当前持有武器的角色UPROPERTY()class ABlasterPlayerController* BlasterOwnerController; // 当前持有武器的角色控制器UPROPERTY()EWeapoType WeaponType;/*** 武器的声音*/UPROPERTY(EditAnywhere)class USoundCue* EquipSound;bool IsEmpty();
FORCEINLINE EWeapoType GetWeaponType() const { return WeaponType; }
FORCEINLINE int32 GetAmmo() const { return Ammo; }
FORCEINLINE int32 GetMagCapacity() const { return MagCapacity; }
bool AWeapon::IsEmpty()
{return Ammo 0;
}void AWeapon::OnRep_Ammo()
{//BlasterOwnerCharacter BlasterOwnerCharacter nullptr ? CastABlasterCharacter(GetOwner()) : BlasterOwnerCharacter;SetHUDAmmo();
}void AWeapon::SpendRound()
{Ammo FMath::Clamp(Ammo - 1,0,MagCapacity);SetHUDAmmo();
}void AWeapon::SetHUDAmmo()
{BlasterOwnerCharacter BlasterOwnerCharacter nullptr ? CastABlasterCharacter(GetOwner()) : BlasterOwnerCharacter;if (BlasterOwnerCharacter){BlasterOwnerController BlasterOwnerController nullptr ? CastABlasterPlayerController(BlasterOwnerCharacter-Controller) : BlasterOwnerController;if (BlasterOwnerController){BlasterOwnerController-SetHUDWeaponAmmo(Ammo);}}
} 3.5.因为新添加了两个显示弹药数量的地方所以给PlayerController添加设置界面的函数 void SetHUDWeaponAmmo(int32 Ammo);void SetHUDCarriedAmmo(int32 Ammo);
void ABlasterPlayerController::SetHUDWeaponAmmo(int32 Ammo)
{BlasterHUD BlasterHUD nullptr ? CastAABasterHUD(GetHUD()) : BlasterHUD;bool bHUDValid BlasterHUD BlasterHUD-CharacterOverlay BlasterHUD-CharacterOverlay-WeaponAmmoAmount;if (bHUDValid){FString AmmoText FString::Printf(TEXT(%d), Ammo); // FloorToInt 向下取整BlasterHUD-CharacterOverlay-WeaponAmmoAmount-SetText(FText::FromString(AmmoText));}
}void ABlasterPlayerController::SetHUDCarriedAmmo(int32 Ammo)
{BlasterHUD BlasterHUD nullptr ? CastAABasterHUD(GetHUD()) : BlasterHUD;bool bHUDValid BlasterHUD BlasterHUD-CharacterOverlay BlasterHUD-CharacterOverlay-CarriedAmmoAmount;if (bHUDValid){FString CarriedAmmoText FString::Printf(TEXT(%d), Ammo); // FloorToInt 向下取整BlasterHUD-CharacterOverlay-CarriedAmmoAmount-SetText(FText::FromString(CarriedAmmoText));}
} 3.6添加重新加载弹药功能当前武器弹药的数量播放换弹动画的功能 /* 换弹 */UFUNCTION(Server, Reliable)void ServerReload();/* 换弹 *//* 处理换弹 */void HandleReload();/* 处理换弹 *//** 重新加载弹药函数 */void Reload();/** 处理设置完成战斗状态 */UFUNCTION(BlueprintCallable)void FinishReloading();/** 计算重新加载弹药的数量 */int32 AmountToReload();//当前装备的武器弹药UPROPERTY(ReplicatedUsing OnRep_CarriedAmmo)int32 CarriedAmmo;UFUNCTION()void OnRep_CarriedAmmo();bool CanFire();// 是否可以开火函数UPROPERTY(ReplicatedUsing OnRep_CombatState)ECombatState CombatState ECombatState::ECS_Unoccupied;UFUNCTION()void OnRep_CombatState();void InitializeCarriedAmmo();TMapEWeapoType, int32 CarriedAmmoMap;
void UCombatComponent::OnRep_CarriedAmmo()
{Controller Controller nullptr ? CastABlasterPlayerController(Character-Controller) : Controller;if (Controller){Controller-SetHUDCarriedAmmo(CarriedAmmo);}
}bool UCombatComponent::CanFire()
{if (EquippedWeapon nullptr) return false;return !EquippedWeapon-IsEmpty() bCanFire CombatState ECombatState::ECS_Unoccupied;
}void UCombatComponent::OnRep_CombatState()
{switch (CombatState){case ECombatState::ECS_Reloading:HandleReload();break;case ECombatState::ECS_Unoccupied:if (bFireButtonPressed){Fire();}break;}
}void UCombatComponent::FinishReloading()
{if (Character nullptr) return;if (Character-HasAuthority()){CombatState ECombatState::ECS_Unoccupied;UpdateAmmoValues();}if (bFireButtonPressed){Fire();}
}void UCombatComponent::HandleReload()
{Character-PlayReloadMontage();
}void UCombatComponent::Reload()
{if (CarriedAmmo 0 CombatState ! ECombatState::ECS_Reloading){ServerReload();}
}void UCombatComponent::ServerReload_Implementation()
{if (Character nullptr || EquippedWeapon nullptr) return;CombatState ECombatState::ECS_Reloading;HandleReload();
}int32 UCombatComponent::AmountToReload()
{if (EquippedWeapon nullptr) return 0;int32 RoomInMag EquippedWeapon-GetMagCapacity() - EquippedWeapon-GetAmmo();if (CarriedAmmoMap.Contains(EquippedWeapon-GetWeaponType())){int32 AmountCarried CarriedAmmoMap[EquippedWeapon-GetWeaponType()];int32 Least FMath::Min(RoomInMag,AmountCarried);return FMath::Clamp(RoomInMag, 0, Least);}return 0;
}void UCombatComponent::InitializeCarriedAmmo() beginplay中调用需要检查HasAuthority()
{CarriedAmmoMap.Emplace(EWeapoType::EWT_AssaultRifle, StartingARAmmo);
} 3.7.在装备武器时调用
if (CarriedAmmoMap.Contains(EquippedWeapon-GetWeaponType())){CarriedAmmo CarriedAmmoMap[EquippedWeapon-GetWeaponType()];}Controller Controller nullptr ? CastABlasterPlayerController(Character-Controller) : Controller;if (Controller){Controller-SetHUDCarriedAmmo(CarriedAmmo);}if (EquippedWeapon-EquipSound){UGameplayStatics::PlaySoundAtLocation(this,EquippedWeapon-EquipSound,Character-GetActorLocation());}if (EquippedWeapon-IsEmpty()){Reload();} 3.8.蓝图设置
