前言

hello大家好久没见，之所以隔了这么久才更新并不是因为我又放弃了这个项目，而是接下来要制作的工作太忙碌了，每次我都花了很长的时间解决完一个部分，然后就没力气打开CSDN写文章就直接睡觉去了，现在终于有时间整理下我这半个月都做了什么内容

废话少说，接下来我将介绍我做的几个代表性场景，主要是如标题说的，制作更多地图，更多敌人，更多可交互对象

另外，我的Github已经更新了，想要查看最新的内容话请到我的Github主页下载工程吧：

一、第一个代表性场景

1.制作更多敌人

我们先把制作好创建吧，还是老规矩先用tk2dTilemap绘制好基础的地图样貌并添加上Collider：

然后堆叠素材添加上去，这样一个场景就做好了：

首先当然是从Town跳下井里的第一个场景Crossroads_01，这里我们设置Town到Crossroads_01的TransitionPoint为top2：

然后回到Crossroads中我们设置好全部的TransitionPoint，这个top1别管：

然后我们添加上敌人，其实这里敌人没什么要讲的因为都是我们之前就做过的，直接预制体拖上去就完事了

主要是要修复这个Zombie的bug，我们之前做的Walker.cs脚本有问题，现在让我们修复bug，问题在EndStopping中：我就说之前怎么会莫名其妙的转身，

然后我们在面板中重新设置好参数：

2.制作更多可交互对象

这个场景里可交互的貌似只有这个杆，我们添加好它的顶部和底部并设置好位置，添加上layer然后新建脚本：BreakablePole.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class BreakablePole : MonoBehaviour,IHitResponder
{[SerializeField] private SpriteRenderer spriteRenderer;[SerializeField] private Sprite brokenSprite;[SerializeField] private float inertBackgroundThreshold;[SerializeField] private float inertForegroundThreshold;[SerializeField] private AudioSource audioSourcePrefab;[SerializeField] private RandomAudioClipTable hitClip;[SerializeField] private GameObject slashImpactPrefab;[SerializeField] private Rigidbody2D top;protected void Reset(){inertBackgroundThreshold = -1f;inertForegroundThreshold = -1f;}protected void Start(){float z = transform.position.z;if(z < inertBackgroundThreshold || z > inertForegroundThreshold){enabled = false;return;}}public void Hit(HitInstance damageInstance){int cardinalDirection = DirectionUtils.GetCardinalDirection(damageInstance.Direction);if (cardinalDirection != 2 && cardinalDirection != 0){return;}spriteRenderer.color = new Color(spriteRenderer.color.r, spriteRenderer.color.g, spriteRenderer.color.b,0f);Transform transform = Instantiate(slashImpactPrefab).transform;transform.eulerAngles = new Vector3(0f, 0f, Random.Range(340f, 380f));Vector3 localScale = transform.localScale;localScale.x = ((cardinalDirection == 2) ? -1f : 1f);localScale.y = 1f;hitClip.SpawnAndPlayOneShot(audioSourcePrefab, base.transform.position);if (top != null){top.gameObject.SetActive(true);float num = (cardinalDirection == 2) ? Random.Range(120, 140) : Random.Range(40, 60);top.transform.localScale = new Vector3(localScale.x, localScale.y, top.transform.localScale.z);top.velocity = new Vector2(Mathf.Cos(num * 0.017453292f), Mathf.Sin(num * 0.017453292f)) * 5f;top.transform.Rotate(new Vector3(0f, 0f, num));base.enabled = false;}}
}

然后设置好参数：

二、第二个代表性场景

1.制作更多敌人

然后就是大家喜闻乐见的长场景Crossroads_07,这个场景相当于一个区域的中转站，既可以向左走去虫爷爷和苍绿之境，或者打boss躁郁的毛里克，亦可以向右走去打假骑士和苍蝇之母，鹿角站，矿井等等，不过这些都是后话了，我们先来把地图做好，添加上对应的TranstionPoint:

其实做到这里我才意识到要把这四个 TranstionPoint做成预制体。

然后敌人自然是到处飞的苍蝇fly了：

2.制作可交互对象

为了让场景看起来生动，我们可以添加背景板里飞走的蚊子buzzer，用particlesystem来实现

第二个：

然后就是踩一下会发出声音的平台：

我们来给它们新建一个脚本LiftPlatform.cs：实现了个功能当角色踩上去时上下移动一下，播放粒子系统和声音：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class LiftPlatform : MonoBehaviour
{public GameObject part1;public GameObject part2;public ParticleSystem dustParticle;public AudioSource source;private float part1_start_y;private float part2_start_y;private int state;private float timer;private void Start(){part1_start_y = part1.transform.position.y;part2_start_y = part2.transform.position.y;}private void Update(){if(state == 1){if (timer < 0.125f){part1.transform.position = new Vector3(part1.transform.position.x, part1_start_y - timer * 0.75f, part1.transform.position.z);part2.transform.position = new Vector3(part2.transform.position.x, part2_start_y - timer * 0.75f, part2.transform.position.z);timer += Time.deltaTime;}else{part1.transform.position = new Vector3(part1.transform.position.x, part1_start_y - 0.09f, part1.transform.position.z);part2.transform.position = new Vector3(part2.transform.position.x, part2_start_y - 0.09f, part2.transform.position.z);state = 2;timer = 0.12f;}}if(state == 2){if (timer > 0f){part1.transform.position = new Vector3(part1.transform.position.x, part1_start_y - timer * 0.75f, part1.transform.position.z);part2.transform.position = new Vector3(part2.transform.position.x, part2_start_y - timer * 0.75f, part2.transform.position.z);timer -= Time.deltaTime;return;}part1.transform.position = new Vector3(part1.transform.position.x, part1_start_y, part1.transform.position.z);part2.transform.position = new Vector3(part2.transform.position.x, part2_start_y, part2.transform.position.z);state = 0;}}private void OnCollisionEnter2D(Collision2D collision){if(state == 0 && collision.collider.gameObject.layer != LayerMask.NameToLayer("Item") && collision.gameObject.layer != LayerMask.NameToLayer("Particle") &&  collision.gameObject.layer != LayerMask.NameToLayer("Enemies") && collision.GetSafeContact().Normal.y < 0.1f){source.pitch = Random.Range(0.85f, 1.15f);source.Play();dustParticle.Play();state = 0;timer = 0f;}}}

三、第三个代表性场景

1.制作更多的敌人

其实这个场景我就想将新制作的敌人的：没错就是这个拿骨钉盾牌的僵尸虫

我们回到tk2dSprite和tk2danimator给它创建好：

你只需要记住，A是anticipate攻击准备阶段的动画，L是Lunge突刺动画，S是攻击时的动画，CD是冷却时候的动画，然后剩下的dddd。这个Bump就是反弹骨钉攻击的动画。OK说的差不多了，然后Unsheild和sheild动画就是反过来的。

然后就是添加相应的脚本到场景中：

s上面的脚本我在之前的文章都讲过了，除了这个EnemyDeathEffects：

using System;
using HutongGames.PlayMaker;
using UnityEngine;
using UnityEngine.Audio;public class EnemyDeathEffects : MonoBehaviour
{[SerializeField] private GameObject corpsePrefab;[SerializeField] private bool corpseFacesRight;[SerializeField] private float corpseFlingSpeed;[SerializeField] public Vector3 corpseSpawnPoint;[SerializeField] private string deathBroadcastEvent;[SerializeField] private Vector3 effectOrigin;[SerializeField] private bool lowCorpseArc;[SerializeField] private EnemyDeathTypes enemyDeathType;[SerializeField] protected AudioSource audioPlayerPrefab;[SerializeField] protected AudioEvent enemyDeathSwordAudio;[SerializeField] protected AudioEvent enemyDamageAudio;[SerializeField] protected AudioClip enemyDeathSwordClip;[SerializeField] protected AudioClip enemyDamageClip;[SerializeField] private AudioMixerSnapshot audioSnapshotOnDeath;[SerializeField] protected GameObject deathWaveInfectedPrefab;[SerializeField] protected GameObject deathWaveInfectedSmallPrefab;[SerializeField] private bool recycle;[SerializeField] private bool rotateCorpse; //尸体需要旋转吗[SerializeField] protected GameObject dustPuffMedPrefab;[SerializeField] protected GameObject deathPuffLargePrefab;protected GameObject corpse;private bool didFire;[HideInInspector]public bool doKillFreeze = true;protected void Start(){PreInstantiate();}public void PreInstantiate(){if(!corpse && corpsePrefab){corpse = Instantiate(corpsePrefab, transform.position + corpseSpawnPoint, Quaternion.identity, transform);tk2dSprite[] componentInChildrens = corpse.GetComponentsInChildren<tk2dSprite>(true);for (int i = 0; i < componentInChildrens.Length; i++){componentInChildrens[i].ForceBuild();}corpse.SetActive(false);}}public void RecieveDeathEvent(float? attackDirection, bool resetDeathEvent = false, bool spellBurn = false, bool isWatery = false){if (didFire)return;didFire = true;if(corpse != null){EmitCorpse(attackDirection, isWatery, spellBurn);}if (!isWatery){EmitEffects();}if (doKillFreeze){GameManager.instance.FreezeMoment(1);}if (enemyDeathType == EnemyDeathTypes.Infected || enemyDeathType == EnemyDeathTypes.LargeInfected || enemyDeathType == EnemyDeathTypes.SmallInfected || enemyDeathType == EnemyDeathTypes.Uninfected ){EmitEssence();}if (audioSnapshotOnDeath != null){audioSnapshotOnDeath.TransitionTo(2f);}if (!string.IsNullOrEmpty(deathBroadcastEvent)){Debug.LogWarningFormat(this, "Death broadcast event '{0}' not implemented!", new object[]{deathBroadcastEvent});}if (resetDeathEvent){FSMUtility.SendEventToGameObject(gameObject, "CENTIPEDE DEATH", false);didFire = false;return;}if (recycle){PlayMakerFSM playMakerFSM = FSMUtility.LocateFSM(gameObject, "health_manager_enemy");if(playMakerFSM != null){playMakerFSM.FsmVariables.GetFsmBool("Activated").Value = false;}HealthManager component2 = GetComponent<HealthManager>();if(component2 != null){component2.SetIsDead(false);}didFire = false;//TODO:return;}Destroy(gameObject);}private void EmitCorpse(float? attackDirection, bool isWatery, bool spellBurn){if (corpse == null)return;corpse.transform.SetParent(null);corpse.transform.SetPositionZ(UnityEngine.Random.Range(-0.08f, -0.09f));corpse.SetActive(true);PlayMakerFSM playMakerFSM = FSMUtility.LocateFSM(corpse, "corpse");if(playMakerFSM != null){FsmBool fsmBool = playMakerFSM.FsmVariables.GetFsmBool("spellBurn");if(fsmBool!= null){fsmBool.Value = false;}}Corpse component = corpse.GetComponent<Corpse>();if (component){component.Setup(isWatery, spellBurn);}if (isWatery){return;}corpse.transform.SetRotation2D(rotateCorpse ? transform.GetRotation2D():0f);if(Mathf.Abs(transform.eulerAngles.z) >= 45f){Collider2D component2 = GetComponent<Collider2D>();Collider2D component3 = corpse.GetComponent<Collider2D>();if(!rotateCorpse && component2 && component3){Vector3 b = component2.bounds.center - component3.bounds.center;b.z = 0f;corpse.transform.position += b;}}float d = 1f;if(attackDirection == null){d = 0f;}int cardinalDirection = DirectionUtils.GetCardinalDirection(attackDirection.GetValueOrDefault());Rigidbody2D component4 = corpse.GetComponent<Rigidbody2D>();if(component4 != null && !component4.isKinematic){float num = corpseFlingSpeed;float num2;switch (cardinalDirection){case 0:num2 = lowCorpseArc ? 10f : 60f;corpse.transform.SetScaleX(corpse.transform.localScale.x * (corpseFacesRight ? -1f : 1f) * Mathf.Sign(transform.localScale.x));break;case 1:num2 = UnityEngine.Random.Range(75f, 105f);num *= 1.3f;break;case 2:num2 = lowCorpseArc ? 170f : 120f;corpse.transform.SetScaleX(corpse.transform.localScale.x * (corpseFacesRight ? 1f : -1f) * Mathf.Sign(transform.localScale.x));break;case 3:num2 = 270f;break;default:num2 = 90f;break;}component4.velocity = new Vector2(Mathf.Cos(num2 * 0.017453292f), Mathf.Sin(num2 * 0.017453292f)) * num * d;}}private void EmitEffects(){EnemyDeathTypes enemyDeathTypes = enemyDeathType;if(enemyDeathTypes == EnemyDeathTypes.Infected){EmitInfectedEffects();return;}if (enemyDeathTypes == EnemyDeathTypes.SmallInfected){EmitSmallInfectedEffects();return;}if (enemyDeathTypes != EnemyDeathTypes.LargeInfected){Debug.LogWarningFormat(this, "Enemy death type {0} not implemented!", new object[]{enemyDeathType});return;}EmitLargeInfectedEffects();}private void EmitLargeInfectedEffects(){AudioEvent audioEvent = default(AudioEvent);audioEvent.Clip = enemyDeathSwordClip;audioEvent.PitchMin = 0.75f;audioEvent.PitchMax = 0.75f;audioEvent.Volume = 1f;audioEvent.SpawnAndPlayOneShot(audioPlayerPrefab, transform.position);audioEvent = default(AudioEvent);audioEvent.Clip = enemyDamageClip;audioEvent.PitchMin = 0.75f;audioEvent.PitchMax = 0.75f;audioEvent.Volume = 1f;audioEvent.SpawnAndPlayOneShot(audioPlayerPrefab, transform.position);if(corpse != null){SpriteFlash component = corpse.GetComponent<SpriteFlash>();if(component != null){component.flashInfected();}}if (!(deathPuffLargePrefab == null)){Instantiate(deathPuffLargePrefab, transform.position + effectOrigin, Quaternion.identity);}ShakeCameraIfVisible("AverageShake");if (!(deathWaveInfectedPrefab == null)){GameObject gameObject = Instantiate(deathWaveInfectedPrefab, transform.position + effectOrigin, Quaternion.identity);gameObject.transform.SetScaleX(2f);gameObject.transform.SetScaleY(2f);}GlobalPrefabDefaults.Instance.SpawnBlood(transform.position + effectOrigin, 75, 80, 20f, 25f, 0f, 360f, null);}private void EmitSmallInfectedEffects(){AudioEvent audioEvent = default(AudioEvent);audioEvent.Clip = enemyDeathSwordClip;audioEvent.PitchMin = 1.2f;audioEvent.PitchMax = 1.4f;audioEvent.Volume = 1f;audioEvent.SpawnAndPlayOneShot(audioPlayerPrefab, transform.position);audioEvent = default(AudioEvent);audioEvent.Clip = enemyDamageClip;audioEvent.PitchMin = 1.2f;audioEvent.PitchMax = 1.4f;audioEvent.Volume = 1f;audioEvent.SpawnAndPlayOneShot(audioPlayerPrefab, transform.position);if (deathWaveInfectedSmallPrefab != null){GameObject gameObject = Instantiate(deathWaveInfectedSmallPrefab, transform.position + effectOrigin,Quaternion.identity);Vector3 localScale = gameObject.transform.localScale;localScale.x = 0.5f;localScale.y = 0.5f;gameObject.transform.localScale = localScale;}GlobalPrefabDefaults.Instance.SpawnBlood(transform.position + effectOrigin, 8, 10, 15f, 20f, 0, 360, null);}private void EmitInfectedEffects(){EmitSound();if(corpse != null){SpriteFlash component = corpse.GetComponent<SpriteFlash>();if(component != null){component.flashInfected();}}GameObject gameObject = Instantiate(deathWaveInfectedPrefab, transform.position + effectOrigin, Quaternion.identity);gameObject.transform.SetScaleX(1.25f);gameObject.transform.SetPositionY(1.25f);GlobalPrefabDefaults.Instance.SpawnBlood(transform.position + effectOrigin, 8, 10, 15f, 20f, 0, 360, null);Instantiate(dustPuffMedPrefab, transform.position + effectOrigin, Quaternion.identity);ShakeCameraIfVisible("EnemyKillShake");}private void EmitSound(){enemyDeathSwordAudio.SpawnAndPlayOneShot(audioPlayerPrefab, transform.position);enemyDamageAudio.SpawnAndPlayOneShot(audioPlayerPrefab, transform.position);}private void EmitEssence(){//TODO:和梦之钉有关的PlayerData playerData = GameManager.instance.playerData;if (!playerData.hasDreamNail){return; }}protected void ShakeCameraIfVisible(string eventName){Renderer renderer = GetComponent<Renderer>();if (renderer == null){renderer = GetComponentInChildren<Renderer>();}if (renderer != null && renderer.isVisible){GameCameras.instance.cameraShakeFSM.SendEvent(eventName);}}}

在面板中添加好参数后，我们就到HealthManager中：

public class HealthManager : MonoBehaviour, IHitResponder
{private EnemyDeathEffects enemyDeathEffects;protected void Awake(){enemyDeathEffects = GetComponent<EnemyDeathEffects>();}public void Die(float? attackDirection, AttackTypes attackType, bool ignoreEvasion){if (isDead){ return;}if (sprite){sprite.color = Color.white;}FSMUtility.SendEventToGameObject(gameObject, "ZERO HP", false);if (hasSpecialDeath){NonFatalHit(ignoreEvasion);return;}isDead = true;if(damageHero != null){damageHero.damageDealt = 0;}if(battleScene != null && !notifiedBattleScene){PlayMakerFSM playMakerFSM = FSMUtility.LocateFSM(battleScene, "Battle Control");if(playMakerFSM != null){FsmInt fsmInt = playMakerFSM.FsmVariables.GetFsmInt("Battle Enemies");if(fsmInt != null){fsmInt.Value--;notifiedBattleScene = true;}}}if (enemyDeathEffects != null){if (attackType == AttackTypes.Generic){enemyDeathEffects.doKillFreeze = false;}enemyDeathEffects.RecieveDeathEvent(attackDirection, deathReset, attackType == AttackTypes.Spell, false);}SendDeathEvent();Destroy(gameObject); //TODO:}
}

还有我们将蚊子那期介绍的老朋友攻击距离检测，警戒距离检测

还有类似于玩家的slash的polygon collider2d，别忘了给它们添加上damagehero脚本

还有一个就是当僵尸虫进入冲刺状态上播放的粒子系统dust：

接下来就到了我们老朋友playmakerFSM登场了，老规矩我先贴出来变量和事件然后逐个讲状态：

第一个状态当然是初始化了：

每一帧都检测玩家是否到可视范围和攻击范围了

判断玩家位置：

我们先做好playmakerFSM自定义脚本：

using HutongGames.PlayMaker;
using UnityEngine;[ActionCategory("Hollow Knight")]
public class SetInvincible : FsmStateAction
{[UIHint(UIHint.Variable)]public FsmOwnerDefault target;public FsmBool Invincible;public FsmInt InvincibleFromDirection;public override void Reset(){target = new FsmOwnerDefault();Invincible = null;InvincibleFromDirection = null;}public override void OnEnter(){GameObject safe = target.GetSafe(this);if (safe != null){HealthManager component = safe.GetComponent<HealthManager>();if (component != null){if (!Invincible.IsNone){component.IsInvincible = Invincible.Value;}if (!InvincibleFromDirection.IsNone){component.InvincibleFromDirection = InvincibleFromDirection.Value;}}}Finish();}}

using HutongGames.PlayMaker;
using UnityEngine;[ActionCategory("Hollow Knight")]
public class SetWalkerFacing : WalkerAction
{public FsmBool walkRight;public FsmBool randomStartDir;public override void Reset(){base.Reset();walkRight = new FsmBool{UseVariable = true};randomStartDir = new FsmBool();}/// <summary>/// 调用Walker.cs中的ChangeFacing函数来改变朝向/// </summary>/// <param name="walker"></param>protected override void Apply(Walker walker){if (randomStartDir.Value){walker.ChangeFacing((Random.Range(0, 2) == 0) ? -1 : 1);return;}if (!walkRight.IsNone){walker.ChangeFacing(walkRight.Value ? 1 : -1);}}}

剩下三个都差不多，你只需要设置好tk2d动画，Lung1 Speed和Lung2 Speed的正负，判断不同方向的事件，以及sheild格挡的方向：

触发BLOCKED HIT的事件该执行的状态：

这个BLOCKED HIT的事件在HealthManager.cs中会触发的，让我们回到HealthManager.cs脚本中：

 public void Invincible(HitInstance hitInstance){int cardinalDirection = DirectionUtils.GetCardinalDirection(hitInstance.GetActualDirection(transform));directionOfLastAttack = cardinalDirection;FSMUtility.SendEventToGameObject(gameObject, "BLOCKED HIT", false);FSMUtility.SendEventToGameObject(hitInstance.Source, "HIT LANDED", false);if (!(GetComponent<DontClinkGates>() != null)){FSMUtility.SendEventToGameObject(gameObject, "HIT", false);if(hitInstance.AttackType == AttackTypes.Nail){if(cardinalDirection == 0){HeroController.instance.RecoilLeft();}else if(cardinalDirection == 2){HeroController.instance.RecoilRight();}}Vector2 v;Vector3 eulerAngles;if (boxCollider != null){switch (cardinalDirection){case 0:v = new Vector2(transform.GetPositionX() + boxCollider.offset.x - boxCollider.size.x * 0.5f, hitInstance.Source.transform.GetPositionY());eulerAngles = new Vector3(0f, 0f, 0f);break;case 1:v = new Vector2(hitInstance.Source.transform.GetPositionX(), Mathf.Max(hitInstance.Source.transform.GetPositionY(), transform.GetPositionY() + boxCollider.offset.y - boxCollider.size.y * 0.5f));eulerAngles = new Vector3(0f, 0f, 90f);break;case 2:v = new Vector2(transform.GetPositionX() + boxCollider.offset.x + boxCollider.size.x * 0.5f, hitInstance.Source.transform.GetPositionY());eulerAngles = new Vector3(0f, 0f, 180f);break;case 3:v = new Vector2(hitInstance.Source.transform.GetPositionX(), Mathf.Min(hitInstance.Source.transform.GetPositionY(), transform.GetPositionY() + boxCollider.offset.y + boxCollider.size.y * 0.5f));eulerAngles = new Vector3(0f, 0f, 270f);break;default:break;}}else{v = transform.position;eulerAngles = new Vector3(0f, 0f, 0f);}}evasionByHitRemaining = 0.15f;}

那么这个方法在哪里被调用呢，当然是我们的HIT方法了，如果你还有印象，这个就是继承接口IHitResponder要实现的方法：

public void Hit(HitInstance hitInstance){if (isDead){return;}if(evasionByHitRemaining > 0f) { return;}if(hitInstance.DamageDealt < 0f){return;}FSMUtility.SendEventToGameObject(hitInstance.Source, "DEALT DAMAGE", false);int cardinalDirection = DirectionUtils.GetCardinalDirection(hitInstance.GetActualDirection(transform));if (IsBlockingByDirection(cardinalDirection, hitInstance.AttackType)){Invincible(hitInstance);return;}TakeDamage(hitInstance);}

判断当前攻击方向是否格挡：

[Header("Invincible")][SerializeField] private bool invincible;[SerializeField] private int invincibleFromDirection;public bool IsBlockingByDirection(int cardinalDirection,AttackTypes attackType){
//法术攻击无法格挡if(attackType == AttackTypes.Spell && gameObject.CompareTag("Spell Vulnerable")){return false;}
//不是无敌无法格挡if (!invincible){return false;}
//没有确切的方向无法格挡if(invincibleFromDirection == 0){return true;}switch (cardinalDirection){case 0:{int num = invincibleFromDirection;if (num <= 5){if (num != 1 && num != 5){return false;}}else if (num != 8 && num != 10){return false;}return true;}   case 1:{int num = invincibleFromDirection;return num == 2 || num - 5 <= 4;}case 2:{int num = invincibleFromDirection;if (num <= 6){if (num != 3 && num != 6){return false;}}else if (num != 9 && num != 11){return false;}return true;}case 3:{int num = invincibleFromDirection;return num == 4 || num - 7 <= 4;}default:return false;}}

格挡以后自然是要对玩家发起攻击了：

首先进入准备阶段：
