前言
Hello大家好久不见，隔了一天没发文章是因为这期的工程也挺复杂的，警告：此篇文章难度偏高，非常不适合刚刚入门的或者没看过我前几期的读者，之所以做了这么久是因为一堆奇奇怪怪的bug真的差点给我整崩溃了然后有些素材我又找不到只能对着Texture2D去PS一张张扣下来都给我整笑了，请读者如果在阅读后感到身体不适请立刻退出这篇文章。
这期我们的主题是：制作法术系统的回血机制和法球机制，友情提示我盲猜会有一堆图片，所以用流量的请检查自己流量是否够用。
一、制作法术系统的回血机制
1.制作动画以及使用UNITY编辑器编辑
还是老规矩，我们来为小骑士添加几个新的tk2dSprite和tk2dSpriteAnimation:
我们把Knight文件夹中所有和Foucs有关的文件夹里面的Sprite全部拖进去，然后点击Apply：
然后就是创建动画了：
然后还有特效效果SpellEffect的tk2dSprite和tk2dSpriteAnimation:这些都是我在PS
为我们的小骑士生成一个新的子对象叫Focus Effect，为里面添加几个新的子对象：
Lines Anim:
Dust R:
Dust L只需要改变Transform的值即可:
其中的PlayerMaker就是上一期我们讲的延迟游戏对象SetActive = false
2.使用代码和PlayMakerFSM制作法术系统
接下来就是用代码来制作法术系统了，首先到PlayerData.cs中我们来添加几个新的变量都是和法术有关的，以及一些方法主要是获得和设置Int和Bool类型的变量：
using System;
using System.Collections.Generic;
using System.Reflection;
using GlobalEnums;
using UnityEngine;
[Serializable]
public class PlayerData
{
private static PlayerData _instance;
public static PlayerData instance
{
get
{
if(_instance == null)
{
_instance = new PlayerData();
}
return _instance;
}
set
{
_instance = value;
}
}
public bool disablePause;
public int health;
public int maxHealth;
public int maxHealthBase;
public int prevHealth;
public int nailDamage;
public int maxMP; //最大MP容量
public int MPCharge; //当前MP存储量
public int MPReverse; //花费的MP
public int MPReverseMax; //花费的最大MP
public bool soulLimited; //是否灵魂容量被限制了
public int focusMP_amount; //聚集法术所需要的MP
public bool hasDash;
public bool canDash;
public bool hasBackDash;
public bool canBackDash;
public bool hasSpell; //是否有法术
public int fireballLevel;//火球法术等级，0表示没有
public int quakeLevel;//地震法术等级，0表示没有
public int screamLevel;//狂啸法术等级，0表示没有
public bool overcharmed;
public bool gotCharm_7; //快速聚集
public bool equippedCharm_7;
public bool gotCharm_10; //英勇者勋章
public bool equippedCharm_10;
public bool gotCharm_11; //吸虫之巢
public bool equippedCharm_11;
public bool gotCharm_17;
public bool equippedCharm_17;
public bool gotCharm_19; //萨满之石
public bool equippedCharm_19;
public bool gotCharm_28; //乌恩符咒
public bool equippedCharm_28;
public bool gotCharm_31; //冲刺大师
public bool equippedCharm_31;
public bool gotCharm_34; //深度聚集
public bool equippedCharm_34;
public int CurrentMaxHealth
{
get
{
return maxHealth;
}
}
protected PlayerData()
{
SetupNewPlayerData();
}
public void Reset()
{
SetupNewPlayerData();
}
private void SetupNewPlayerData()
{
disablePause = false;
health = 5;
maxHealth = 5;
maxHealthBase = 5;
prevHealth = health;
nailDamage = 5;
maxMP = 99;
MPCharge = 0;
MPReverse = 0;
MPReverseMax = 0;
soulLimited = false;
focusMP_amount = 33;
hasDash = true; //测试阶段先设置为true方便测试
canDash = true;
hasBackDash = false;
canBackDash = false;
hasSpell = false;
fireballLevel = 0;
quakeLevel = 0;
screamLevel = 0;
overcharmed = false;
gotCharm_7 = false;
equippedCharm_7 = false;
gotCharm_10 = false;
equippedCharm_10 = false;
gotCharm_11 = false;
equippedCharm_11 = false;
gotCharm_17 = false;
equippedCharm_17 = false;
gotCharm_19 = false;
equippedCharm_19 = false;
gotCharm_28 = false;
equippedCharm_28 = false;
gotCharm_31 = true;
equippedCharm_31 = true;
gotCharm_34 = false;
equippedCharm_34 = false;
}
public void AddHealth(int amount)
{
if (health + amount >= maxHealth)
{
health = maxHealth;
}
else
{
health += amount;
}
if (health >= CurrentMaxHealth)
{
health = maxHealth;
}
}
public void TakeHealth(int amount)
{
if(amount > 0 && health == maxHealth && health != CurrentMaxHealth)
{
health = CurrentMaxHealth;
}
if(health - amount < 0)
{
health = 0;
return;
}
health -= amount;
}
public void MaxHealth()
{
health = CurrentMaxHealth;
}
public bool AddMPCharge(int amount)
{
bool result = false;
if(soulLimited && maxMP != 66)
{
maxMP = 66;
}
if (!soulLimited && maxMP != 99)
{
maxMP = 99;
}
if(MPCharge + amount > maxMP)
{
if(MPReverse < MPReverseMax)
{
MPReverse += amount - (maxMP - MPCharge);
result = true;
if(MPReverse > MPReverseMax)
{
MPReverse = MPReverseMax;
}
}
MPCharge = maxMP;
}
else
{
MPCharge += amount;
result = true;
}
return result;
}
public void TakeMP(int amount)
{
if(amount < MPCharge)
{
MPCharge -= amount;
if(MPCharge < 0)
{
MPCharge = 0;
return;
}
}
else
{
MPCharge = 0;
}
}
public int GetInt(string intName)
{
if (string.IsNullOrEmpty(intName))
{
Debug.LogError("PlayerData: Int with an EMPTY name requested.");
return -9999;
}
FieldInfo fieldInfo = GetType().GetField(intName);
if(fieldInfo != null)
{
return (int)fieldInfo.GetValue(instance);
}
Debug.LogError("PlayerData: Could not find int named " + intName + " in PlayerData");
return -9999;
}
public bool GetBool(string boolName)
{
if (string.IsNullOrEmpty(boolName))
{
return false;
}
FieldInfo field = GetType().GetField(boolName);
if (field != null)
{
return (bool)field.GetValue(instance);
}
Debug.Log("PlayerData: Could not find bool named " + boolName + " in PlayerData");
return false;
}
}
回到我们的HeroActions.cs中，我们来给法术系统添加几个新行为，一个是回血机制行为的focus，一个是快速法术的quickcast：
using System;
using InControl;
public class HeroActions : PlayerActionSet
{
public PlayerAction left;
public PlayerAction right;
public PlayerAction up;
public PlayerAction down;
public PlayerTwoAxisAction moveVector;
public PlayerAction attack;
public PlayerAction jump;
public PlayerAction dash;
public PlayerAction cast;
public PlayerAction focus;
public PlayerAction quickCast;
public HeroActions()
{
left = CreatePlayerAction("Left");
left.StateThreshold = 0.3f;
right = CreatePlayerAction("Right");
right.StateThreshold = 0.3f;
up = CreatePlayerAction("Up");
up.StateThreshold = 0.3f;
down = CreatePlayerAction("Down");
down.StateThreshold = 0.3f;
moveVector = CreateTwoAxisPlayerAction(left, right, down, up);
moveVector.LowerDeadZone = 0.15f;
moveVector.UpperDeadZone = 0.95f;
attack = CreatePlayerAction("Attack");
jump = CreatePlayerAction("Jump");
dash = CreatePlayerAction("Dash");
cast = CreatePlayerAction("Cast");
focus = CreatePlayerAction("Focus");
quickCast = CreatePlayerAction("QuickCast");
}
}
来到InputHandler.cs中把刚刚创建的变量添加到方法中：
using System;
using System.Collections;
using System.Collections.Generic;
using GlobalEnums;
using InControl;
using UnityEngine;
public class InputHandler : MonoBehaviour
{
public InputDevice gameController;
public HeroActions inputActions;
public void Awake()
{
inputActions = new HeroActions();
}
public void Start()
{
MapKeyboardLayoutFromGameSettings();
if(InputManager.ActiveDevice != null && InputManager.ActiveDevice.IsAttached)
{
}
else
{
gameController = InputDevice.Null;
}
Debug.LogFormat("Input Device set to {0}.", new object[]
{
gameController.Name
});
}
private void MapKeyboardLayoutFromGameSettings()
{
AddKeyBinding(inputActions.up, "UpArrow");
AddKeyBinding(inputActions.down, "DownArrow");
AddKeyBinding(inputActions.left, "LeftArrow");
AddKeyBinding(inputActions.right, "RightArrow");
AddKeyBinding(inputActions.attack, "Z");
AddKeyBinding(inputActions.jump, "X");
AddKeyBinding(inputActions.dash, "D");
AddKeyBinding(inputActions.cast, "F");
AddKeyBinding(inputActions.quickCast, "Q");
}
private static void AddKeyBinding(PlayerAction action, string savedBinding)
{
Mouse mouse = Mouse.None;
Key key;
if (!Enum.TryParse(savedBinding, out key) && !Enum.TryParse(savedBinding, out mouse))
{
return;
}
if (mouse != Mouse.None)
{
action.AddBinding(new MouseBindingSource(mouse));
return;
}
action.AddBinding(new KeyBindingSource(new Key[]
{
key
}));
}
}
接下来就是到HeroAnimationController.cs我们添加几个新的方法，因为在空洞骑士这个游戏中，回血的时候不能移动和播放其它动画，所以我们得创建一个属性来记录是否可以播放动画还有一个ActorStates记录失去控制之前的动画。
public ActorStates stateBeforeControl { get; private set; }
public bool controlEnabled { get; private set; }
public void StartControl()
{
actorStates = heroCtrl.hero_state;
controlEnabled = true;
PlayIdle();
}
public void StopControl()
{
if(controlEnabled)
{
controlEnabled = false;
stateBeforeControl = actorStates;
}
}
using System;
using GlobalEnums;
using UnityEngine;

}
private bool CanPlayTurn()
{
return !animator.IsPlaying("Wake Up Ground") && !animator.IsPlaying("Hazard Respawn"); ;
}
}
来到HeroControllerStates.cs，除了我们要创建几个和法术有关的变量外，还需要获得某个状态的方法和设置某个状态的方法：
[Serializable]
public class HeroControllerStates
{
public bool facingRight;
public bool onGround;
public bool wasOnGround;
public bool attacking;
public bool altAttack;
public bool upAttacking;
public bool downAttacking;
public bool inWalkZone;
public bool jumping;
public bool falling;
public bool dashing;
public bool backDashing;
public bool touchingWall;
public bool wallSliding;
public bool willHardLand;
public bool recoilFrozen;
public bool recoiling;
public bool recoilingLeft;
public bool recoilingRight;
public bool freezeCharge;
public bool focusing;
public bool dead;
public bool hazardDeath;
public bool invulnerable;
public bool preventDash;
public bool preventBackDash;
public bool dashCooldown;
public bool backDashCooldown;
public bool isPaused;
public HeroControllerStates()
{
facingRight = false;
onGround = false;
wasOnGround = false;
attacking = false;
altAttack = false;
upAttacking = false;
downAttacking = false;
inWalkZone = false;
jumping = false;
falling = false;
dashing = false;
backDashing = false;
touchingWall = false;
wallSliding = false;
willHardLand = false;
recoilFrozen = false;
recoiling = false;
recoilingLeft = false;
recoilingRight = false;
freezeCharge = false;
focusing = false;
dead = false;
hazardDeath = false;
invulnerable = false;
preventDash = false;
preventBackDash = false;
dashCooldown = false;
backDashCooldown = false;
isPaused = false;
}
/// <summary>
/// 设置一个新的状态（通常用在playmakerFSM上）
/// </summary>
/// <param name="stateName"></param>
/// <param name="value"></param>
public void SetState(string stateName, bool value)
{
FieldInfo field = GetType().GetField(stateName);
if (field != null)
{
try
{
field.SetValue(HeroController.instance.cState, value);
return;
}
catch (Exception ex)
{
string str = "Failed to set cState: ";
Exception ex2 = ex;
Debug.LogError(str + ((ex2 != null) ? ex2.ToString() : null));
return;
}
}
Debug.LogError("HeroControllerStates: Could not find bool named" + stateName + "in cState");
}
/// <summary>
/// 获取一个新的状态（通常用在playmakerFSM上）
/// </summary>
/// <param name="stateName"></param>
/// <returns></returns>
public bool GetState(string stateName)
{
FieldInfo field = GetType().GetField(stateName);
if (field != null)
{
return (bool)field.GetValue(HeroController.instance.cState);
}
Debug.LogError("HeroControllerStates: Could not find bool named" + stateName + "in cState");
return false;
}
}终于来到HeroController.cs中，我们来设置回血机制所需要的变量：
private bool drainMP; //是否正在流走MP
private float drainMP_timer; //流走MP的计时器
private float drainMP_time; //流走MP花费的时间
private float MP_drained; //已经流走的MP数量
private float focusMP_amount; //使用focus回血所需要的MP数量
private float preventCastByDialogueEndTimer;
public PlayMakerFSM spellControl;
在Update函数中：
if (drainMP)
{
drainMP_timer += Time.deltaTime;
while (drainMP_timer >= drainMP_time) //drainMP_time在无护符下等于0.027
{
MP_drained += 1f;
drainMP_timer -= drainMP_time;
TakeMp(1);
if(MP_drained == focusMP_amount)
{
MP_drained -= drainMP_time;
proxyFSM.SendEvent("HeroCtrl-FocusCompleted");
}
}
}
preventCastByDialogueEndTimer -= Time.deltaTime;
设置获取MP和消耗MP的方法，增加血量和消耗血量的方法，是否能聚集，是否能释放法术，能否输入和忽略输入，失去控制和重新获得控制：
public void AddMPCharge(int amount)
{
int mpreverse = playerData.MPReverse;
playerData.AddMPCharge(amount);
if(playerData.MPReverse != mpreverse && gm)
{
}
}
public void SetMPCharge(int amount)
{
playerData.MPCharge = amount;
//TODO:
}
public void SoulGain()
{
int num;
if(playerData.MPCharge < playerData.maxMP)
{
num = 11;
}
else
{
num = 6;
}
int mpreverse = playerData.MPReverse;
playerData.AddMPCharge(num);
if(playerData.MPReverse != mpreverse)
{
}
}
public void TakeMp(int amount)
{
if(playerData.MPCharge > 0)
{
playerData.TakeMP(amount);
if(amount > 1)
{
}
}
}
public void AddHealth(int amount)
{
playerData.AddHealth(amount);
proxyFSM.SendEvent("HeroCtrl-Healed");
}
public void TakeHealth(int amount)
{
playerData.TakeHealth(amount);
proxyFSM.SendEvent("HeroCtrl-HeroDamaged");
}
public void MaxHealth()
{

playerData.MaxHealth();
}
public void StartMPDrain(float time)
{
Debug.LogFormat("Start MP Drain");
drainMP = true;
drainMP_timer = 0f;
MP_drained = 0f;
drainMP_time = time; //

}
public void StopMPDrain()
{

}
public bool CanFocus()
{
return !gm.isPaused && hero_state != ActorStates.no_input && !cState.dashing && !cState.backDashing && (!cState.attacking || attack_time > ATTACK_RECOVERY_TIME) && !cState.recoiling && cState.onGround && !cState.recoilFrozen && !cState.hazardDeath && CanInput();
}

这个SoulGain()我们要在HealthManager.cs中来调用：
public void TakeDamage(HitInstance hitInstance)
{
Debug.LogFormat("Enemy Take Damage");
int cardinalDirection = DirectionUtils.GetCardinalDirection(hitInstance.GetActualDirection(transform));
directionOfLastAttack = cardinalDirection;

if(recoil != null)
{
recoil.RecoilByDirection(cardinalDirection,hitInstance.MagnitudeMultiplier);
}
switch (hitInstance.AttackType)
{
case AttackTypes.Nail:
if(hitInstance.AttackType == AttackTypes.Nail && enemyType !=3 && enemyType != 6)
{
HeroController.instance.SoulGain();
}
Vector3 position = (hitInstance.Source.transform.position + transform.position) * 0.5f + effectOrigin;
break;
case AttackTypes.Generic:
break;
case AttackTypes.Spell:
break;
}
if(hitEffectReceiver != null)
{
hitEffectReceiver.ReceiverHitEffect(hitInstance.GetActualDirection(transform));
}
int num = Mathf.RoundToInt((float)hitInstance.DamageDealt * hitInstance.Multiplier);
hp = Mathf.Max(hp - num, -50);

你可能注意到代码中关于法术有关的代码少之又少，这是因为我打算用playmakerFSM制作整个法术系统，给小骑士创建一个新的playMakerFSM就叫Spell Control：
底下是一个基本的法术系统playmakerFSM，所以这就是我说的图片很多小心流量
我们先来把变量和事件都添加上去：
需要特别设置的变量如下所示：
然后我将逐个介绍每种状态和每种状态要用某些行为的含义：
首先一开始先顿个一帧切换到FINISHED
初始化Init，主要是获取需要的子对象：
初始化结束后进入不活跃Inactive状态：
这两个是我新建的自定义脚本，用于监听Cast和QuickCast的按键输入：
using UnityEngine;
namespace HutongGames.PlayMaker.Actions
{
[ActionCategory("Controls")]
[Tooltip("Listens for an action button press (using HeroActions InControl mappings).")]
public class ListenForCast : FsmStateAction
{
[Tooltip("Where to send the event.")]
public FsmEventTarget eventTarget;
public FsmEvent wasPressed;
public FsmEvent wasReleased;
public FsmEvent isPressed;
public FsmEvent isNotPressed;
public FsmBool activeBool;
public bool stateEntryOnly;
private GameManager gm;
private InputHandler inputHandler;
public override void Reset()
{
eventTarget = null;
activeBool = new FsmBool
{
UseVariable = true
};
}
public override void OnEnter()
{
gm = GameManager.instance;
inputHandler = gm.GetComponent<InputHandler>();
CheckForInput();
if (stateEntryOnly)
{
Finish();
}
}
public override void OnUpdate()
{
CheckForInput();
}
private void CheckForInput()
{
if (!gm.isPaused && (activeBool.IsNone || activeBool.Value))
{
if (inputHandler.inputActions.cast.WasPressed)
{
Fsm.Event(wasPressed);
}
if (inputHandler.inputActions.cast.WasReleased)
{
Fsm.Event(wasReleased);
}
if (inputHandler.inputActions.cast.IsPressed)
{
Fsm.Event(isPressed);
}
if (!inputHandler.inputActions.cast.IsPressed)
{
Fsm.Event(isNotPressed);
}
}
}
}
}
using UnityEngine;

}
public override void OnEnter()
{

inputHandler = gm.GetComponent<InputHandler>();
}
public override void OnUpdate()
{

{
Fsm.Event(isPressed);
}
if (!inputHandler.inputActions.quickCast.IsPressed)
{
Fsm.Event(isNotPressed);
}
}
}
}
}
如果按下按钮后就判断是否有上下的按键输入，有的话就进入判断地震和狂啸状态，没有的话就等时间到后进入回血状态：
这两个是我新建的自定义脚本，用于监听上Up和下Down的按键输入：
using UnityEngine;
namespace HutongGames.PlayMaker.Actions
{
[ActionCategory("Controls")]
[Tooltip("Listens for an action button press (using HeroActions InControl mappings).")]
public class ListenForDown : FsmStateAction
{
[Tooltip("Where to send the event.")]
public FsmEventTarget eventTarget;
public FsmEvent wasPressed;
public FsmEvent wasReleased;
public FsmEvent isPressed;
public FsmEvent isNotPressed;
[UIHint(UIHint.Variable)]
public FsmBool isPressedBool;
public bool stateEntryOnly;
private GameManager gm;
private InputHandler inputHandler;
public override void Reset()
{
eventTarget = null;
}
public override void OnEnter()
{
gm = GameManager.instance;
inputHandler = gm.GetComponent<InputHandler>();
CheckForInput();
if (stateEntryOnly)
{
Finish();
}
}
public override void OnUpdate()
{
CheckForInput();
}
private void CheckForInput()
{
if (!gm.isPaused)
{
if (inputHandler.inputActions.down.WasPressed)
{
Fsm.Event(wasPressed);
}
if (inputHandler.inputActions.down.WasReleased)
{
Fsm.Event(wasReleased);
}
if (inputHandler.inputActions.down.IsPressed)
{
Fsm.Event(isPressed);
if (!isPressedBool.IsNone)
{
isPressedBool.Value = true;
}
}
if (!inputHandler.inputActions.down.IsPressed)
{
Fsm.Event(isNotPressed);
if (!isPressedBool.IsNone)
{
isPressedBool.Value = false;
}
}
}
}
}
}
using UnityEngine;

public class ListenForUp : FsmStateAction

}
}

{
Fsm.Event(isNotPressed);
if (!isPressedBool.IsNone)
{
isPressedBool.Value = false;
}
}
}
}
}
}
如果进入Can Focus?状态通过HeroController.cs的CanFocus（）方法和GameManager里面的PlayerData的Int值类型够不够来判断：
这里有一个自定义行为脚本CallMethodProper .cs：
using System;
using System.Reflection;
using UnityEngine;
namespace HutongGames.PlayMaker.Actions
{
[ActionCategory(ActionCategory.ScriptControl)]
public class CallMethodProper : FsmStateAction
{
[RequiredField]
[Tooltip("The game object that owns the Behaviour.")]
public FsmOwnerDefault gameObject;
[RequiredField]
[UIHint(UIHint.Behaviour)]
[Tooltip("The Behaviour that contains the method to start as a coroutine.")]
public FsmString behaviour;
[UIHint(UIHint.Method)]
[Tooltip("Name of the method to call on the component")]
public FsmString methodName;
[Tooltip("Method paramters. NOTE: these must match the method's signature!")]
public FsmVar[] parameters;
[ActionSection("Store Result")]
[UIHint(UIHint.Variable)]
[Tooltip("Store the result of the method call.")]
public FsmVar storeResult;
private UnityEngine.Object cachedBehaviour;
private Type cachedType;
private MethodInfo cachedMethodInfo;
private ParameterInfo[] cachedParameterInfo;
private object[] parametersArray;
private string errorString;
private MonoBehaviour component;
public override void OnEnter()
{
parametersArray = new object[parameters.Length];
DoMethodCall();
Finish();
}
private void DoMethodCall()
{
if (behaviour.Value == null)
{
Finish();
return;
}
GameObject ownerDefaultTarget = base.Fsm.GetOwnerDefaultTarget(gameObject);
if (ownerDefaultTarget == null)
{
return;
}
component = (ownerDefaultTarget.GetComponent(behaviour.Value) as MonoBehaviour);
if (component == null)
{
LogWarning("CallMethodProper: " + ownerDefaultTarget.name + " missing behaviour: " + behaviour.Value);
return;
}
if (cachedMethodInfo == null)
{
errorString = string.Empty;
if (!DoCache())
{
Debug.LogError(errorString);
Finish();
return;
}
}
object value = null;
if (cachedParameterInfo.Length == 0)
{
value = cachedMethodInfo.Invoke(cachedBehaviour, null);
}
else
{
for (int i = 0; i < parameters.Length; i++)
{
FsmVar fsmVar = parameters[i];
fsmVar.UpdateValue();
parametersArray[i] = fsmVar.GetValue();
}
try
{
value = cachedMethodInfo.Invoke(cachedBehaviour, parametersArray);
}
catch (Exception ex)
{
string str = "CallMethodProper error on ";
string ownerName = Fsm.OwnerName;
string str2 = " -> ";
Exception ex2 = ex;
Debug.LogError(str + ownerName + str2 + ((ex2 != null) ? ex2.ToString() : null));
}
}
if (storeResult.Type != VariableType.Unknown)
{
storeResult.SetValue(value);
}
}
private bool DoCache()
{
cachedBehaviour = component;
cachedType = component.GetType();
cachedMethodInfo = cachedType.GetMethod(methodName.Value);
if (cachedMethodInfo == null)
{
errorString = errorString + "Method Name is invalid: " + methodName.Value + "\n";
Finish();
return false;
}
cachedParameterInfo = cachedMethodInfo.GetParameters();
return true;
}
}
}
然后就到了设置动画播放Set Slug Anim的时候了，这里我们通过有无护符乌恩之形（equippedCharm_28）来判断播放哪种回血动画：
然后就到了开始回血的Focus Start状态了：设置HeroControllerState.freezeCharge状态为true，HeroControllerState.focusing为true，并开始播放音效了，玩家失去控制并停止动画控制的方法，播放新的动画等待FocusStartTimer结束后进入下一个状态：
到了设置回血速度Set Focus Speed的状态：通过判断是否装备快速聚集（equippedCharm_7）护符 来设置不同的回血速度：
到了设置深度回血速度Deep Focus Speed的状态同样也是根据护符来判断的：
进入判断是否是Slug?状态：我们还没做到这个部分所以就不管了，让它进slug speed状态（不过肯定不会进的我们不会触发SLUG事件）
然后进入Focus状态：设置子对象Line Anim的MeshRenderere为true，然后播放里面的动画，并设置Dust L和Dust R的emission为true，执行函数StartMPDrain（TimePerMPDrain）,
自定义脚本SetParticleEmissionRate.cs：
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 SetParticleEmissionRate : FsmStateAction
{
[RequiredField]
[Tooltip("The particle emitting GameObject")]
public FsmOwnerDefault gameObject;
public FsmFloat emissionRate;
public bool everyFrame;
private ParticleSystem emitter;
public override void Reset()
{
gameObject = null;
emissionRate = null;
everyFrame = false;
}
public override void OnEnter()
{
if(gameObject != null)
{
GameObject ownerDefaultTarget = Fsm.GetOwnerDefaultTarget(gameObject);
if (ownerDefaultTarget)
{
emitter = ownerDefaultTarget.GetComponent<ParticleSystem>();
}
DoSetEmitRate();
if (!everyFrame)
{
Finish();
}
}
}
public override void OnUpdate()
{
DoSetEmitRate();
}
private void DoSetEmitRate()
{
if (emitter)
{
emitter.emissionRate = emissionRate.Value;
}
}
}
}
如果Focus完成后，我们的HeroController.cs就会向小骑士的另一个playmaker叫proxyFSM发送事件：HeroCtrl-FocusCompleted，然后proxyFSM就会向自身所有的playmaker状态机（包括我们上面创建的spell control）发送FOCUS COMPLETED事件,然后就可以进入Spore Cloud状态了：
if (drainMP)
{
drainMP_timer += Time.deltaTime;
while (drainMP_timer >= drainMP_time) //drainMP_time在无护符下等于0.027
{
MP_drained += 1f;
drainMP_timer -= drainMP_time;
TakeMp(1);
if(MP_drained == focusMP_amount)
{
MP_drained -= drainMP_time;
proxyFSM.SendEvent("HeroCtrl-FocusCompleted");
}
}
}我们来到proxyFSM创建新的事件：
Sproe状态中判断冷却时间以及是否有两个护符，如果有equippedCharm_10英勇者勋章就执行DUNG事件进入Dung Cloud状态：
进入Dung Cloud状态：其实我还没做，所以就不用介绍了，进入FINISHED进入Set HP Amount状态
状态Set HP Amount：通过护符判断该回多少滴血：
来到focusHealth状态：首先执行SpriteFlash.cs脚本中的flashFocusHeal（这个后面会讲，要留意）方法，播放一次性的AudioSource，执行HeroController.cs中的StopMPDrain（）方法停止MP流失，小骑士播放动画Focus Get，执行HeroController.cs中的AddHealth（）方法增加一滴血，然后记录满血的值maxHealth，等0.2s进入下一个状态。
这里有几个自定义的行为脚本我先贴出来吧：
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 AudioPlayerOneShotSingle : FsmStateAction
{
[RequiredField]
[Tooltip("The object to spawn. Select Audio Player prefab.")]
public FsmGameObject audioPlayer;
[RequiredField]
[Tooltip("Object to use as the spawn point of Audio Player")]
public FsmGameObject spawnPoint;
[ObjectType(typeof(AudioClip))]
public FsmObject audioClip;
public FsmFloat pitchMin;
public FsmFloat pitchMax;
public FsmFloat volume = 1f;
public FsmFloat delay;
public FsmGameObject storePlayer;
private AudioSource audio;
private float timer;
public override void Reset()
{
spawnPoint = null;
pitchMin = 1f;
pitchMax = 1f;
volume = 1f;
}
public override void OnEnter()
{
timer = 0f;
if(delay.Value == 0f)
{
DoPlayRandomClip();
Finish();
}
}
public override void OnUpdate()
{
if (delay.Value > 0f)
{
timer += Time.deltaTime;
return;
}
DoPlayRandomClip();
Finish();
}
private void DoPlayRandomClip()
{
if(!audioPlayer.IsNone && !spawnPoint.IsNone && spawnPoint.Value != null)
{
GameObject value = audioPlayer.Value;
Vector3 position = spawnPoint.Value.transform.position;
Vector3 up = Vector3.up;
if (audioPlayer.Value != null)
{
GameObject gameObject = GameObject.Instantiate(audioPlayer.Value, position, Quaternion.Euler(up));
audio = gameObject.GetComponent<AudioSource>();
storePlayer.Value = gameObject;
AudioClip audioClip = this.audioClip.Value as AudioClip;
float pitch = UnityEngine.Random.Range(pitchMin.Value, pitchMax.Value);
audio.pitch = pitch;
audio.volume = volume.Value;
if (audioClip != null)
{
audio.PlayOneShot(audioClip);
return;
}
}
else
{
Debug.LogError("AudioPlayer object not set!");
}
}
}
}
}
判断是否满血Full HP?的状态：如果MP小于回血所需要的MP就执行CANCEL事件回到Focus状态，FINISHED事件进入Set Full状态：
Set Full状态：
Focus Get Finish状态：完成回血后的状态，淡出音量，HeroControllerState.focusing等于false，Lines Anim播放Focus Effect End动画，小骑士自身播放Focus Get Once动画，停止Dust L,Dust R的粒子系统的Emission为0，执行HeroController的StopMPDrain，设置指为0.02,等0.3秒后进入下一个状态：
这里有一个自定义行为脚本FadeAudio.cs:
using UnityEngine;
namespace HutongGames.PlayMaker.Actions
{
[ActionCategory(ActionCategory.Audio)]
[Tooltip("Sets the Volume of the Audio Clip played by the AudioSource component on a Game Object.")]
public class FadeAudio : ComponentAction<AudioSource>
{
[RequiredField]
[CheckForComponent(typeof(AudioSource))]
public FsmOwnerDefault gameObject;
public FsmFloat startVolume;
public FsmFloat endVolume;
public FsmFloat time;
private float timeElapsed;
private float timePercentage;
private bool fadingDown;
public override void Reset()
{
gameObject = null;
startVolume = 1f;
endVolume = 0f;
time = 1f;
}
public override void OnEnter()
{
if(startVolume.Value > endVolume.Value)
{
fadingDown = true;
}
else
{
fadingDown = false;
}
GameObject ownerDefaultTarget = Fsm.GetOwnerDefaultTarget(gameObject);
if (UpdateCache(ownerDefaultTarget))
{
audio.volume = startVolume.Value;
}
}
public override void OnUpdate()
{
DoSetAudioVolume();
}
public override void OnExit()
{
GameObject ownerDefaultTarget = Fsm.GetOwnerDefaultTarget(gameObject);
if (UpdateCache(ownerDefaultTarget))
{
audio.volume = endVolume.Value;
}
}
private void DoSetAudioVolume()
{
GameObject ownerDefaultTarget = Fsm.GetOwnerDefaultTarget(gameObject);
if (UpdateCache(ownerDefaultTarget))
{
timeElapsed += Time.deltaTime;
timePercentage = timeElapsed / time.Value * 100f;
float num = (endVolume.Value - startVolume.Value) * (timePercentage / 100f);
audio.volume = audio.volume + num;
if (fadingDown && audio.volume <= endVolume.Value)
{
audio.volume = endVolume.Value;
Finish();
}
else if (!fadingDown && audio.volume >= endVolume.Value)
{
audio.volume = endVolume.Value;
Finish();
}
timeElapsed = 0f;
}
}
}
}
到了Regain Control重新获得控制的状态：HeroControllerState里面的状态freezeCharge设置为false停止播放Audio，将Lines Anim的meshrenderer设置为false，执行HeroController的RegainControl()和StartAnimationControl（）两个方法
检测是否要回到不活跃状态的Back in?:如果是就回，不是的话进入Can Focus状态：
Grace Check:宽限期检测，如果是第一次则进入First Grace Check状态，如果不是就进入Focus Cancel状态：
First Grace Check状态：执行SetMPCharge()函数直接设置成初始MP值即可：
至此我们完成了完整的法术系统的回血机制，这些大多都是通过playmakerFSM状态机来实现的。
二、制作法术系统的法球机制
1.制作动画以及使用UNITY编辑器编辑
首先先把图片和动画导进来吧：
OK接下来我们就来制作法球了，继续到Spell Control的playmakerFSM中，当BUTTON DOWN选择BUTTON UP事件后，先判断Can Cast?:
选择法术类型Spell Chocie:
由于我只做了法球，所以法球和地震的状态我们就直接CANCEL到Has Fireball？状态即可：
直接进入Cast状态的Quick Cast，我们还是一样先判断能否Cast：
同样也是选择：
有火球法术吗？Has Fireball?：获取playerdata的fireballLevel。
是否是在墙边：如果是的话就执行FlipSprite（）翻转人物：
准备执行fireball阶段：小骑士播放动画Fireball Antic，执行函数RelinquishControl（）和StopAnimationControl（），AffectedByGravity（）设置为false，小骑士速度设置为0，监听Cast的输入，我们可以在InputManager中设置好。
检测火球等级的Level Check：
火球为1级的Fireball 1：
播放动画Fireball1 Cast，执行函数TakeMp（）消耗MP，生成一个预制体，这个是法球生成位置的预制体，等会再说，发送事件FINISHED到 Fireball Recoil
发送火球的后坐力Fireball Recoil状态：
Spell End状态：播放结束后执行函数RegainControl（）和StartAnimationControl（）回到inactive状态
2.制作法术系统的法球机制
接下来就是要制作预制体Fireball Top
这个particles我找不到素材，你们就自由发挥吧：
这个Fireball Blast的playmakerFSM内容如下：就是等动画播放完成后回收它：
using UnityEngine;
namespace HutongGames.PlayMaker.Actions
{
[ActionCategory("Object Pool")]
[Tooltip("Recycles the Owner of the Fsm. Useful for Object Pool spawned Prefabs that need to kill themselves, e.g., a projectile that explodes on impact.")]
public class RecycleSelf : FsmStateAction
{
// TODO:后续有了ObjectPool的时候就替换掉
public override void OnEnter()
{
if (Owner != null)
GameObject.Destroy(Owner);
Finish();
}
}
}
再给Fireball Top一个新的FSM：Fireball Cast
每一个状态如下，我感觉不用我介绍了，就直接贴图自己看看吧：
这里的自定义脚本SpawnObjectFromGlobalPool.cs如下：
using UnityEngine;
namespace HutongGames.PlayMaker.Actions

public class SpawnObjectFromGlobalPool : FsmStateAction

{

}
euler = ((!rotation.IsNone) ? rotation.Value : spawnPoint.Value.transform.eulerAngles);
}
else
{

{

}

{

}
if (gameObject != null)
{

storeObject.Value = value;

}
Finish();

这个Fireball就是生成的有实际伤害和碰撞体积的火球，我们一会来创建
这个Spell Fluke就是装备吸虫之巢护符后释放法术放出来的虫子，我们先给它一个空的游戏对象日后再来做。
最后我们来创建火球预制体：Fireball它有Rigibody2d,collider2d,tk2dsprite和animation，以及两个playmakerFSM。
它拥有一个检测地形的子对象：
Dribble R和Dribble L都是粒子系统，我也找不到素材所以你们自由发挥吧：
particle system同理也自由发挥吧：
先从我们熟悉的playmakerFSMdamages_enemy开始，这一个我们在制作玩家攻击系统就介绍过了，其实都差不多只需要改改伤害和后坐力倍数即可：
剩下两个状态的行为就是把collider改成parent和gparent即可：
然后创建一个新的playmakerFSM叫Fireball Control：
第一个状态是设置造成的伤害：
Pause状态：开启meshrenderer和设置collider激活状态
自定义行为脚本如下：
using UnityEngine;
namespace HutongGames.PlayMaker.Actions
{
[ActionCategory(ActionCategory.Physics2D)]
[Tooltip("Set BoxCollider2D to active or inactive. Can only be one collider on object.")]
public class SetCollider : FsmStateAction

[Tooltip("The particle emitting GameObject")]
public FsmOwnerDefault gameObject;
public FsmBool active;
public override void Reset()
{
gameObject = null;
active = false;
}
public override void OnEnter()
{
if (gameObject != null)
{
BoxCollider2D component = Fsm.GetOwnerDefaultTarget(gameObject).GetComponent<BoxCollider2D>();
if (component != null)
{
component.enabled = active.Value;
}
}
Finish();
}
}
}
初始化判断左和右：
碰撞检测Idle状态：

总结
为了方便测试，我们来给GameManager游戏对象添加一个新的脚本就叫CheatManager.cs方便我们测试用：
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class CheatManager : MonoBehaviour
{
private GameManager gm;
[SerializeField]public PlayerData playerData;
private void Awake()
{
gm = GameManager.instance;
playerData = gm.playerData;
}
private void Update()
{
if (Input.GetKeyDown(KeyCode.P))
{
playerData.hasDash = true;
playerData.MPCharge = playerData.maxMP;
playerData.fireballLevel = 1;
}
}
}
进入游戏，我们按P键获得满蓝状态和拥有火球术的状态：
按下Q键和F键试一下效果：
掉了15滴血，完美
下一期我们来设置一下相机还有布置一下场景吧。
