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，接下来我将继续介绍我做的几个代表性场景，，可能你会说：“怎么标题还和上期一模一样”，那当然是没办法的事情，毕竟一期讲完这么多场景，敌人，可交互对象你没看睡着我都快写睡着了，OK我们接着来制作更多地图，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：

GitHub - ForestDango/Hollow-Knight-Demo: A new Hollow Knight Demo after 2 years!

一、第一个代表性场景

1.制作敌人僵尸跳跳虫更多敌人

我突然找到一个有四个新类型敌人的场景，让我们先来介绍这四少吧，但首先还是先搭建好场景

可能看到这里你还不知道这对应的是游戏里的哪个场景，但只要我加上场景景色一切将豁然开朗

往上走去鹿角站，往右走去打苍蝇之母因此记得添加好对应的TransitionPoint。

我们先来制作最简单的僵尸跳跳虫：做好相对应的tk2dsprite和tk2dspriteAnimator。

添加相对应的脚本：

 老朋友Attack Range攻击距离：

落地状态下的灰尘粒子系统Dust:

创建一个名字为“Zombie Swipe”的playmakerFSM，然后老规矩贴出事件和变量：

逐个讲状态：

初始化阶段：

准备阶段：逐帧判断攻击距离和可视范围内：

判断玩家位置：

攻击准备阶段：

起飞阶段 

落地阶段：

冷却阶段：

回到空闲阶段：

重置Walker脚本的行为：

        这样一个简单跳跳僵尸虫就完成了。

2.制作敌人阿斯匹德更多可交互对象

        然后是制作敌人阿斯匹德，注意，这个不是折磨玩家的原始阿斯匹德，而是只会喷一个方向的：

首先添加好tk2dsprite和tk2dSpriteAnimator:

长开火和短开火的动画：

添加好相应的脚本：

除此之外，我们还要制作攻击用的子弹

我们先来制作玩家离开攻击距离的playmakerFSM：

这里会设置Spitter的playmakerFSM里面的bool变量unalert Range        以及设置bool变量Can See Hero

回到阿斯匹德spitter中，我们首先创建一个之前讲过的playmakerFSM叫flyer_receive_direction_msg。这个我之前讲蚊子那期用过，就是接收不同方向信息的，

然后才是我们的重点“spitter” FSM：

初始化状态：播放音效和动画，确认初始时的朝向，空闲状态漫无目的的IdleBuzz，通过Alert Range New来判断是否在攻击距离里，并check Can See Hero.

如果满足上述两个条件直接进入Alert状态： 

径直向玩家飞去：

判断位置并射线检测：

再飞行一小段距离，朝向玩家：

准备开火阶段：

设置发射的子弹朝向玩家，设置好速度

当玩家离开攻击距离后，回到Unalert Frame状态，下一帧再回到Idle状态

 这里我们来创建子弹预制体：

新建一个脚本名字叫EnemyBullet.cs
 

using System.Collections;
using UnityEngine;[RequireComponent(typeof(Rigidbody2D))]
public class EnemyBullet : MonoBehaviour
{public float scaleMin = 1.15f;public float scaleMax = 1.45f;private float scale;[Space]public float stretchFactor = 1.2f;public float stretchMinX = 0.75f;public float stretchMaxY = 1.75f;[Space]public AudioSource audioSourcePrefab;public AudioEvent impactSound;private bool active;private Rigidbody2D body;private tk2dSpriteAnimator anim;private Collider2D col;private void Awake(){body = GetComponent<Rigidbody2D>();anim = GetComponent<tk2dSpriteAnimator>();col = GetComponent<Collider2D>();}private void OnEnable(){active = true;scale = Random.Range(scaleMin, scaleMax);col.enabled = true;body.isKinematic = false;body.velocity = Vector2.zero;body.angularVelocity = 0f;anim.Play("Idle");}private void Update(){if (active){float rotation = Random.Range(body.velocity.y,body.velocity.x) * 57.295776f;transform.SetRotation2D(rotation);float num = 1f - body.velocity.magnitude * stretchFactor * 0.01f;float num2 = 1f + body.velocity.magnitude * stretchFactor * 0.01f;if (num2 < stretchMinX){num2 = stretchMinX;}if (num > stretchMaxY){num = stretchMaxY;}num *= scale;num2 *= scale;transform.localScale = new Vector3(num2, num, transform.localScale.z);}}private void OnCollisionEnter2D(Collision2D collision){if (active){active = false;StartCoroutine(Collision(collision.GetSafeContact().Normal, true));}}private void OnTriggerEnter2D(Collider2D collision){if(active && collision.tag == "HeroBox"){active = false;StartCoroutine(Collision(Vector2.zero, false));}}public void OrbitShieldHit(Transform shield){if (active){active = false;Vector2 normal = transform.position - shield.position;normal.Normalize();StartCoroutine(Collision(normal, true));}}private IEnumerator Collision(Vector2 normal, bool doRotation){transform.localScale = new Vector3(scale, scale, transform.localScale.z);body.isKinematic = true;body.velocity = Vector2.zero;body.angularVelocity = 0f;tk2dSpriteAnimationClip impactAnim = anim.GetClipByName("Impact");anim.Play(impactAnim);if (!doRotation || (normal.y >= 0.75f && Mathf.Abs(normal.x) < 0.5f)){transform.SetRotation2D(0f);}else if (normal.y <= 0.75f && Mathf.Abs(normal.x) < 0.5f){transform.SetRotation2D(180f);}else if (normal.x >= 0.75f && Mathf.Abs(normal.y) < 0.5f){transform.SetRotation2D(270f);}else if (normal.x <= 0.75f && Mathf.Abs(normal.y) < 0.5f){transform.SetRotation2D(90f);}impactSound.SpawnAndPlayOneShot(audioSourcePrefab, transform.position);yield return null;col.enabled = false;yield return new WaitForSeconds((impactAnim.frames.Length - 1) / impactAnim.fps);Destroy(gameObject);//TODO:}}

回到Unity编辑器添加好对应的参数,

最后再添加一个子对象，一个小小的亮灯：

3.制作敌人孵化虫和它的孩子

using System;
using UnityEngine;namespace HutongGames.PlayMaker.Actions
{[ActionCategory(ActionCategory.Audio)][Tooltip("Instantiate an Audio Player object and play a oneshot sound via its Audio Source.")]public class AudioPlayerOneShot : FsmStateAction{[RequiredField][CheckForComponent(typeof(AudioSource))][Tooltip("The object to spawn.

using UnityEngine;namespace HutongGames.PlayMaker.Actions
{[ActionCategory(ActionCategory.GameObject)][Tooltip("Spawns a random amount of chosen GameObject from global pool and fires them off in random directions.")]public class FlingObjectsFromGlobalPool : RigidBody2dActionBase{[RequiredField][Tooltip("GameObject to spawn.")]public FsmGameObject gameObject;[Tooltip("GameObject to spawn at (optional).")]public FsmGameObject spawnPoint;[Tooltip("Position.

1.制作敌人沃姆Worm

说起来你看到这名字可能想不起来这是啥怪物，其实就是遗忘十字路中恶心玩家的那个路障

首先是灰尘粒子系统：

这个石头也是粒子系统：

这个也是粒子系统石头，区别在于，上面那个是Idle状态下播放的粒子系统，而这个是在Burst状态下播放的：

这个虫子属于是既能伤害玩家又能伤害敌人的，因此添加上DamageHero和DamageEnemy两个脚本： 

这里我们把将骨钉攻击那期的Nail Slash里面的playmakerfsm“damages_enemy”也给它安排上：

还有自己的Worm Control:

 向上中：

缩回去： 

 已经缩回地里：

是否开启burst rocks的particlesystem：

Burst的时候就在这里开启伤害和Collider： 

自定义行为脚本如下：

using UnityEngine;namespace HutongGames.PlayMaker.Actions
{[ActionCategory("Particle System")][Tooltip("Set particle emission on or off on an object with a particle emitter")]public class SetParticleEmission : FsmStateAction{[RequiredField][Tooltip("The particle emitting GameObject")]public FsmOwnerDefault gameObject;public FsmBool emission;public override void Reset(){gameObject = null;emission = false;}public override void OnEnter(){if (gameObject != null){GameObject ownerDefaultTarget = Fsm.GetOwnerDefaultTarget(gameObject);if (ownerDefaultTarget != null){ownerDefaultTarget.GetComponent<ParticleSystem>().enableEmission = emission.Value;}}Finish();}}
}

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

至此我们制作了一个流动的循环。 

2.制作可交互对象

其实主要就是这些杆子，我们用脚本breakable.cs来制作

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class Breakable : MonoBehaviour,IHitResponder
{private Collider2D bodyCollider;[Tooltip("Renderer which presents the undestroyed object.")][SerializeField] private Renderer wholeRenderer;[Tooltip("List of child game objects which also represent the whole object.")][SerializeField] public  GameObject[] wholeParts;[Tooltip("List of child game objects which represent remnants that remain static after destruction.")][SerializeField] private GameObject[] remnantParts;[SerializeField] private List<GameObject> debrisParts;[SerializeField] private float angleOffset = -60f;[Tooltip("Breakables behind this threshold are inert.")][SerializeField] private float inertBackgroundThreshold;[Tooltip("Breakables in front of this threshold are inert.")][SerializeField] private float inertForegroundThreshold;[Tooltip("Breakable effects are spawned at this offset.")][SerializeField] private Vector3 effectOffset;[Tooltip("Prefab to spawn for audio.")][SerializeField] private AudioSource audioSourcePrefab;[Tooltip("Table of audio clips to play upon break.")][SerializeField] private AudioEvent breakAudioEvent;[Tooltip("Table of audio clips to play upon break.")][SerializeField] private RandomAudioClipTable breakAudioClipTable;[Tooltip("Prefab to spawn when hit from a non-down angle.")][SerializeField] private Transform dustHitRegularPrefab;[Tooltip("Prefab to spawn when hit from a down angle.")][SerializeField] private Transform dustHitDownPrefab;[Tooltip("Prefab to spawn when hit from a down angle.")][SerializeField] private float flingSpeedMin;[Tooltip("Prefab to spawn when hit from a down angle.")][SerializeField] private float flingSpeedMax;[Tooltip("Strike effect prefab to spawn.")][SerializeField] private Transform strikeEffectPrefab;[Tooltip("Nail hit prefab to spawn.")][SerializeField] private Transform nailHitEffectPrefab;[Tooltip("Spell hit effect prefab to spawn.")][SerializeField] private Transform spellHitEffectPrefab;[Tooltip("Object to send HIT event to.")][SerializeField] private GameObject hitEventReciever;[Tooltip("Forward break effect to sibling FSMs.")][SerializeField] private bool forwardBreakEvent;[Space]public Probability.ProbabilityGameObject[] containingParticles;public FlingObject[] flingObjectRegister;private bool isBroken;private void Awake(){bodyCollider = GetComponent<Collider2D>();}protected void Reset(){inertBackgroundThreshold = 1f;inertForegroundThreshold = -1f;effectOffset = new Vector3(0f, 0.5f, 0f);flingSpeedMin = 10f;flingSpeedMax = 17f;}protected void Start(){CreateAdditionalDebrisParts(debrisParts);float z = transform.position.z;if(z > inertBackgroundThreshold || z < inertForegroundThreshold){BoxCollider2D component = GetComponent<BoxCollider2D>();if(component != null){component.enabled = false;}Destroy(this);return;}for (int i = 0; i < remnantParts.Length; i++){GameObject gameObject = remnantParts[i];if(gameObject != null && gameObject.activeSelf){gameObject.SetActive(false);}}angleOffset *= Mathf.Sign(transform.localScale.x);}protected virtual void CreateAdditionalDebrisParts(List<GameObject> debrisParts){}public void Hit(HitInstance damageInstance){if (isBroken){return;}Debug.LogFormat("Breakable Take Hit");float impactAngle = damageInstance.Direction;float num = damageInstance.MagnitudeMultiplier;if(damageInstance.AttackType == AttackTypes.Spell){Instantiate(spellHitEffectPrefab, base.transform.position, Quaternion.identity).SetPositionZ(0.0031f);}else{if (damageInstance.AttackType != AttackTypes.Nail && damageInstance.AttackType != AttackTypes.Generic){impactAngle = 90f;num = 1f;}Instantiate(strikeEffectPrefab, base.transform.position,Quaternion.identity);Vector3 position = (damageInstance.Source.transform.position + base.transform.position) * 0.5f;SpawnNailHitEffect(nailHitEffectPrefab, position, impactAngle);}int cardinalDirection = DirectionUtils.GetCardinalDirection(damageInstance.Direction);Transform transform = dustHitRegularPrefab;float flingAngleMin;float flingAngleMax;Vector3 euler;if (cardinalDirection == 2){angleOffset *= -1f;flingAngleMin = 120f;flingAngleMax = 160f;euler = new Vector3(180f, 90f, 270f);}else if (cardinalDirection == 0){flingAngleMin = 30f;flingAngleMax = 70f;euler = new Vector3(0f, 90f, 270f);}else if (cardinalDirection == 1){angleOffset = 0f;flingAngleMin = 70f;flingAngleMax = 110f;num *= 1.5f;euler = new Vector3(270f, 90f, 270f);}else{angleOffset = 0f;flingAngleMin = 160f;flingAngleMax = 380f;transform = dustHitDownPrefab;euler = new Vector3(-72.5f, -180f, -180f);}if(transform != null){Instantiate(transform, transform.position + effectOffset, Quaternion.Euler(euler));}Break(flingAngleMin, flingAngleMax, num);}private static Transform SpawnNailHitEffect(Transform nailHitEffectPrefab, Vector3 position, float impactAngle){if (nailHitEffectPrefab == null)return null;int cardinalDirection = DirectionUtils.GetCardinalDirection(impactAngle);float y = 1.5f;float minInclusive;float maxInclusive;if (cardinalDirection == 3){minInclusive = 270f;maxInclusive = 290f;}else if (cardinalDirection == 1){minInclusive = 70f;maxInclusive = 110f;}else{minInclusive = 340f;maxInclusive = 380f;}float x = (cardinalDirection == 2) ? -1.5f : 1.5f;Transform transform = Instantiate(nailHitEffectPrefab,position,Quaternion.identity);Vector3 eulerAngles = transform.eulerAngles;eulerAngles.z = Random.Range(minInclusive, maxInclusive);transform.eulerAngles = eulerAngles;Vector3 localScale = transform.localScale;localScale.x = x;localScale.y = y;transform.localScale = localScale;return transform;}public void Break(float flingAngleMin, float flingAngleMax, float impactMultiplier){if (isBroken)return;SetStaticPartsActivation(true);for (int i = 0;

}

 其三个子对象，一个是杆的顶部top，一个是杆的底部base,最后一个是破坏后蹦出来的石头particlesystem：

制作好一个后，我们就可以照此制作更多的这种可破坏的杆子Pole了，

还有这种可破坏的雕塑，原理都是一样的，只不过这个没有头部只有底部，而且有两个粒子系统：

 三、第三个代表性场景

            这个夭折了因为CSDN提示我上传的图片到达上限了，这我是没想到的，没办法这一集只能分为上下两期来讲了，而且下期我将讲述一个非常劲爆的敌人，感兴趣的话就等我一两个小时把内容整理完成发出来吧。

        想看效果的请移步到下一篇文章！！！

        md，我没想到CSDN有规矩24小时内只能上传300张图片，喜提一天冷却时间，大伙只能等我明天再来把这篇和下一篇文章写完了。
