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：
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，

public enum States
{
NotReady,
WaitingForConditions,
Stopped,
Walking,
Turning
}
public enum StopReasons
{
Bored,
Controlled
}
}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
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：
cs
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：
cs
using System;
using HutongGames.PlayMaker;
using UnityEngine;
using UnityEngine.Audio;

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)
{

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：
cs
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：
cs
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();
}
}
cs
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：
cs
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：
cs
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：
cs
[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：
向前冲刺阶段：
攻击阶段，在这里就要打开我们创建的slash的碰撞箱了，同时将僵尸虫的速度位置为0
冷却阶段，关闭碰撞箱：
然后突然虚晃一枪接着对玩家发动二段攻击，没有准备阶段直接进入冲刺攻击阶段
二阶段的冷却：
三阶段的再次冲刺攻击阶段：
三阶段的攻击阶段：
三阶段的冷却阶段，应该不叫冷却而是叫停止攻击阶段：
重置walker状态：
除了自动攻击我们还有主动攻击阶段，内容我就不赘述了直接上图：
还有就是玩家离开可视范围和攻击距离发送LEFT RANGE事件，把举起的盾牌放下来
总结
我们来看看上述讲到的三个场景的效果（上面的UI先别管我之后会完成的）：
虫子的转身没问题的
平台没问题的
然后僵尸盾牌虫：直接攻击Attack 1
它在反击后的攻击是水平方向的，因此我可以下劈它
由于我没做格挡时的动画，虽然不明显但是还是能看到敌人并没有因为我的攻击而受到伤害。。
三段攻击也有，但我忘了截屏了就先这样吧，下一期我们来制作更多的敌人和更多的场景
