根據小兵隊伍更換小兵的皮膚

懶得開UE了，增加一個Minion類繼承基類角色CCharacter

}void AMinion::OnRep_TeamID()
{PickSkinBasedOnTeamID();
}

打開小兵角色藍圖，修改父類

設置一下皮膚

換一個原始皮膚

管理小兵的生成

繼承Actor，命名為MinionBarrack，用來管理小兵的生成

}

放到場景中點擊吸管再點擊這個場景的出生點，來出生

然后你會發現怪疊了兩層，應該是服務器和客戶端都生成了，在生成處加個權威

使用對象池來管理小兵的生成

在角色基類CCharacter中添加判斷死亡函數和移除死亡標簽函數

#pragma region 死亡和復活 (Death and Respawn)
public:bool IsDead() const;void RespawnImmediately();
private:
#pragma endregion

bool ACCharacter::IsDead() const
{return GetAbilitySystemComponent()->HasMatchingGameplayTag(TGameplayTags::Stats_Dead);
}void ACCharacter::RespawnImmediately()
{// 僅在服務器上執行：移除所有帶有“死亡”標簽的激活效果，實現立即復活if (HasAuthority()){GetAbilitySystemComponent()->RemoveActiveEffectsWithGrantedTags(FGameplayTagContainer(TGameplayTags::Stats_Dead));}
}void ACCharacter::DeathMontageFinished()
{if (IsDead()){SetRagdollEnabled(true);}
}

到小兵角色類中添加判斷小兵是否激活的函數

public:// 判斷小兵是否處于激活狀態bool IsActive() const;// 激活小兵（如復活、生成時調用）void Activate();

bool AMinion::IsActive() const
{return !IsDead();
}void AMinion::Activate()
{// 移除死亡標簽，復活RespawnImmediately();
}

UCLASS()
class AMinionBarrack : public AActor
{GENERATED_BODY()
private:// 生成一組小兵(優先用對象池)void SpawnNewGroup();// 從池中獲取可用小兵AMinion* GetNextAvailableMinion() const;// 生成組的定時器句柄FTimerHandle SpawnIntervalTimerHandle;
};

void AMinionBarrack::BeginPlay()
{Super::BeginPlay();// 僅在服務器上定時生成小兵if (HasAuthority()){// 設置定時器，定時批量生成小兵GetWorldTimerManager().SetTimer(SpawnIntervalTimerHandle, this, &AMinionBarrack::SpawnNewGroup, GroupSpawnInterval, true);}
}void AMinionBarrack::SpawnNewGroup()
{// 需要生成的小兵數量int32 i = MinionPerGroup;while (i > 0){// 獲取出生點變換FTransform SpawnTransform = GetActorTransform();// 獲取下一個出生點if (const APlayerStart* NextSpawnSpot = GetNextSpawnSpot()){SpawnTransform = NextSpawnSpot->GetActorTransform();}// 優先復用對象池中的非激活小兵AMinion* NextAvailableMinion = GetNextAvailableMinion();// 對象池內沒有可以用的小兵了就退出循環，生成一個新的小兵if (!NextAvailableMinion) break;NextAvailableMinion->SetActorTransform(SpawnTransform);NextAvailableMinion->Activate();--i;}// 如果對象池不夠，則新建剩余數量的小兵SpawnNewMinions(i);
}AMinion* AMinionBarrack::GetNextAvailableMinion() const
{for (AMinion* Minion : MinionPool){if (!Minion->IsActive()){return Minion;}}return nullptr;
}

想必以及發現了AI小兵的顏色跟自己設置的隊伍顏色有點不對勁了吧，在AI控制器那里，已經強行設置了一個隊伍ID.

void ACAIController::OnPossess(APawn* InPawn)
{Super::OnPossess(InPawn);IGenericTeamAgentInterface* PawnTeamInterface = Cast<IGenericTeamAgentInterface>(InPawn);if (PawnTeamInterface){SetGenericTeamId(PawnTeamInterface->GetGenericTeamId());ClearAndDisableAllSenses();EnableAllSenses();}UAbilitySystemComponent* PawnASC = UAbilitySystemBlueprintLibrary::GetAbilitySystemComponent(InPawn);if (PawnASC){PawnASC->RegisterGameplayTagEvent(TGameplayTags::Stats_Dead, EGameplayTagEventType::NewOrRemoved).AddUObject(this, &ACAIController::PawnDeadTagUpdated);}
}

創建一個持續時間為無限的死亡GE

把他給小兵用上

打死小兵之后的尸體消失，就是在對象池中復活了。

為小兵設置一個目標

public:// 設置小兵的目標（如推進目標、攻擊目標等）void SetGoal(AActor* Goal);
private:// 黑板中用于存儲目標的Key名UPROPERTY(EditDefaultsOnly, Category = "AI")FName GoalBlackboardKeyName = "Goal";

void AMinion::SetGoal(AActor* Goal)
{if (AAIController* AIController = GetController<AAIController>()){if (UBlackboardComponent* BlackboardComponent = AIController->GetBlackboardComponent()){// 修改黑板組件中對應鍵目標的值BlackboardComponent->SetValueAsObject(GoalBlackboardKeyName, Goal);}}
}

創建小兵的時候為其設置該鍵的值

void AMinionBarrack::SpawnNewMinions(int Amt)
{if (Amt <= 0) return;for (int32 i = 0; i < Amt; ++i){// 獲取出生點變換FTransform SpawnTransform = GetActorTransform();// 獲取下一個出生點if (const APlayerStart* NextSpawnSpot = GetNextSpawnSpot()){SpawnTransform = NextSpawnSpot->GetActorTransform();}// 生成小兵AMinion* NewMinion = GetWorld()->SpawnActorDeferred<AMinion>(MinionClass, SpawnTransform, this, nullptr, ESpawnActorCollisionHandlingMethod::AdjustIfPossibleButAlwaysSpawn);// 設置小兵的隊伍IDNewMinion->SetGenericTeamId(BarrackTeamId);// 完成小兵的生成NewMinion->FinishSpawning(SpawnTransform);// 設置小兵的目標NewMinion->SetGoal(Goal);// 添加小兵到小兵池中MinionPool.Add(NewMinion);}
}

到黑板中創建該健

可以讓AI走向設定的目標

添加黑板裝飾器

在值改變的時候就會重啟行為樹，不去追擊設定的目標，轉來打發現的敵人

目標跟小兵出生點一點，通過吸管吸取場景的物品

小兵發現你后就會來打你了

設置字體

復制原本的頭部ui，關閉藍條的字體和進度條顯示
