根据小兵队伍更换小兵的皮肤

懒得开UE了，增加一个Minion类继承基类角色CCharacter

// 幻雨喜欢小猫咪#pragma once#include "CoreMinimal.h"
#include "Character/CCharacter.h"
#include "Minion.generated.h"/*** 小兵AI角色类，继承自ACCharacter* 负责小兵的队伍分配、激活状态、目标设置、皮肤切换等功能*/
UCLASS()
class CRUNCH_API AMinion : public ACCharacter
{GENERATED_BODY()public:virtual void SetGenericTeamId(const FGenericTeamId& NewTeamId) override;
private:// 根据队伍ID切换小兵皮肤void PickSkinBasedOnTeamID();// 队伍ID同步时回调（用于网络同步后自动切换皮肤等）virtual void OnRep_TeamID() override;// 队伍ID到对应皮肤的映射表UPROPERTY(EditDefaultsOnly, Category = "Visual")TMap<FGenericTeamId, TObjectPtr<USkeletalMesh>> SkinMap;
};

// 幻雨喜欢小猫咪#include "Minion.h"void AMinion::SetGenericTeamId(const FGenericTeamId& NewTeamId)
{Super::SetGenericTeamId(NewTeamId);PickSkinBasedOnTeamID();
}void AMinion::PickSkinBasedOnTeamID()
{TObjectPtr<USkeletalMesh>* Skin = SkinMap.Find(GetGenericTeamId());if (Skin){GetMesh()->SetSkeletalMesh(*Skin);}
}void AMinion::OnRep_TeamID()
{PickSkinBasedOnTeamID();
}

打开小兵角色蓝图，修改父类

设置一下皮肤

换一个原始皮肤

管理小兵的生成

继承Actor，命名为MinionBarrack，用来管理小兵的生成

void AMinionBarrack::BeginPlay()
{Super::BeginPlay();// 测试用SpawnNewMinions(5);
}const APlayerStart* AMinionBarrack::GetNextSpawnSpot()
{if (SpawnSpots.Num() == 0) return nullptr;++NextSpawnSpotIndex;if (NextSpawnSpotIndex >= SpawnSpots.Num()){NextSpawnSpotIndex = 0;}// 返回出生点return SpawnSpots[NextSpawnSpotIndex];
}void AMinionBarrack::SpawnNewMinions(int Amt)

}

放到场景中点击吸管再点击这个场景的出生点，来出生

然后你会发现怪叠了两层，应该是服务器和客户端都生成了，在生成处加个权威

使用对象池来管理小兵的生成

在角色基类CCharacter中添加判断死亡函数和移除死亡标签函数

#pragma region 死亡和复活 (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()
{// 仅在服务器上执行：移除所有带有“死亡”标签的激活效果，实现立即复活if (HasAuthority()){GetAbilitySystemComponent()->RemoveActiveEffectsWithGrantedTags(FGameplayTagContainer(TGameplayTags::Stats_Dead));}
}void ACCharacter::DeathMontageFinished()
{if (IsDead()){SetRagdollEnabled(true);}
}

到小兵角色类中添加判断小兵是否激活的函数

public:// 判断小兵是否处于激活状态bool IsActive() const;// 激活小兵（如复活、生成时调用）void Activate();

bool AMinion::IsActive() const
{return !IsDead();
}void AMinion::Activate()
{// 移除死亡标签，复活RespawnImmediately();
}

UCLASS()
class AMinionBarrack : public AActor
{GENERATED_BODY()
private:// 生成一组小兵(优先用对象池)void SpawnNewGroup();// 从池中获取可用小兵AMinion* GetNextAvailableMinion() const;// 生成组的定时器句柄FTimerHandle SpawnIntervalTimerHandle;
};

void AMinionBarrack::BeginPlay()
{Super::BeginPlay();// 仅在服务器上定时生成小兵if (HasAuthority()){// 设置定时器，定时批量生成小兵GetWorldTimerManager().SetTimer(SpawnIntervalTimerHandle, this, &AMinionBarrack::SpawnNewGroup, GroupSpawnInterval, true);}
}void AMinionBarrack::SpawnNewGroup()
{// 需要生成的小兵数量int32 i = MinionPerGroup;while (i > 0){// 获取出生点变换FTransform SpawnTransform = GetActorTransform();// 获取下一个出生点if (const APlayerStart* NextSpawnSpot = GetNextSpawnSpot()){SpawnTransform = NextSpawnSpot->GetActorTransform();}// 优先复用对象池中的非激活小兵AMinion* NextAvailableMinion = GetNextAvailableMinion();// 对象池内没有可以用的小兵了就退出循环，生成一个新的小兵if (!NextAvailableMinion) break;NextAvailableMinion->SetActorTransform(SpawnTransform);NextAvailableMinion->Activate();--i;}// 如果对象池不够，则新建剩余数量的小兵SpawnNewMinions(i);
}AMinion* AMinionBarrack::GetNextAvailableMinion() const
{for (AMinion* Minion : MinionPool){if (!Minion->IsActive()){return Minion;}}return nullptr;
}

想必以及发现了AI小兵的颜色跟自己设置的队伍颜色有点不对劲了吧，在AI控制器那里，已经强行设置了一个队伍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);}
}

创建一个持续时间为无限的死亡GE

把他给小兵用上

打死小兵之后的尸体消失，就是在对象池中复活了。

为小兵设置一个目标

public:// 设置小兵的目标（如推进目标、攻击目标等）void SetGoal(AActor* Goal);
private:// 黑板中用于存储目标的Key名UPROPERTY(EditDefaultsOnly, Category = "AI")FName GoalBlackboardKeyName = "Goal";

void AMinion::SetGoal(AActor* Goal)
{if (AAIController* AIController = GetController<AAIController>()){if (UBlackboardComponent* BlackboardComponent = AIController->GetBlackboardComponent()){// 修改黑板组件中对应键目标的值BlackboardComponent->SetValueAsObject(GoalBlackboardKeyName, Goal);}}
}

创建小兵的时候为其设置该键的值

void AMinionBarrack::SpawnNewMinions(int Amt)
{if (Amt <= 0) return;for (int32 i = 0; i < Amt; ++i){// 获取出生点变换FTransform SpawnTransform = GetActorTransform();// 获取下一个出生点if (const APlayerStart* NextSpawnSpot = GetNextSpawnSpot()){SpawnTransform = NextSpawnSpot->GetActorTransform();}// 生成小兵AMinion* NewMinion = GetWorld()->SpawnActorDeferred<AMinion>(MinionClass, SpawnTransform, this, nullptr, ESpawnActorCollisionHandlingMethod::AdjustIfPossibleButAlwaysSpawn);// 设置小兵的队伍IDNewMinion->SetGenericTeamId(BarrackTeamId);// 完成小兵的生成NewMinion->FinishSpawning(SpawnTransform);// 设置小兵的目标NewMinion->SetGoal(Goal);// 添加小兵到小兵池中MinionPool.Add(NewMinion);}
}

到黑板中创建该健

可以让AI走向设定的目标

添加黑板装饰器

在值改变的时候就会重启行为树，不去追击设定的目标，转来打发现的敌人

目标跟小兵出生点一点，通过吸管吸取场景的物品

小兵发现你后就会来打你了

设置字体

复制原本的头部ui，关闭蓝条的字体和进度条显示
