[Unity] 战斗系统学习 12：Switchable 1
小編覺得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.
1. 批量 SmoothDamp 變量的需求
1.1 例子
這是我一個(gè)改到一半的函數(shù)……我懶得改了
這個(gè)函數(shù)的目的是從一個(gè)模式轉(zhuǎn)換到另外一個(gè)模式的時(shí)候開始對(duì)一堆變量在一個(gè)時(shí)間內(nèi) SmoothDamp
目前是只有兩個(gè)變量，所以我可以這么寫，但是萬一我都很多個(gè)變量呢？萬一我要頻繁地修改變量的名字，個(gè)數(shù)啥的呢？
我就感覺很麻煩
本來其實(shí)在不同模式之間切換的時(shí)候，需要 SmoothDamp 的變量其實(shí)是不同的，從 A 到 B 要?jiǎng)尤齻€(gè)變量，但是從 B 到 C 可能就只需要?jiǎng)右粋€(gè)
你要說用狀態(tài)機(jī)把，其實(shí)也沒必要，因?yàn)檫@并沒有 OnEnter OnUpdate OnExist 啥的需求
所以我就想怎么方便地做這個(gè)切換的函數(shù)
1.2 分析
一個(gè) mono 中有一個(gè)變量組，記為 V，一個(gè)表示模式的 Enum 變量，命名為 mode
V 對(duì) mode 的不同值有不同預(yù)設(shè)值，把這些預(yù)設(shè)值做成一個(gè) Struct 命名為 Setting
那么如果我想 V 的值在 mode 變化時(shí)，可以在與 mode 對(duì)應(yīng)的 Setting 之間切換，我可以這么寫
偽代碼
EnumXXX mode; Setting setting0; Setting setting1; Setting setting2; Dictionary<EnumXXX, Setting> SettingDictionary = new Dictionary<EnumXXX, Setting>{{0,setting0},{1,setting1},{2,setting2}} V = SettingDictionary[mode];但是如果我想要 V 在 setting 之間使用 smoothdamp 過渡，我就必須要對(duì) setting 中的每一項(xiàng)都創(chuàng)建一個(gè)緩存變量 velocity 輸入到 smoothdamp 函數(shù)里面，感覺這樣有點(diǎn)麻煩
并且對(duì)于每一個(gè)不同的 V 我都要寫一堆 smoothdamp 代碼
比如如果 V 要轉(zhuǎn)到 setting0
偽代碼
V1 = Math.SmoothDamp(V1, setting0.V1, Velocity1, smoothTime); V2 = Math.SmoothDamp(V2, setting0.V2, Velocity2, smoothTime); V3 = Math.SmoothDamp(V3, setting0.V3, Velocity3, smoothTime);這樣就會(huì)很冗余……但是又不能做成一個(gè)大的列表然后遍歷這個(gè)列表 smoothdamp
比如
偽代碼
for(int i = 1;i < V.Count; ++i) {V[i] = Math.SmoothDamp(V[i], setting0[i], Velocity[i], smoothTime); }因?yàn)?V 中的變量的類型可能是不同的，不能放到一個(gè)列表中
要放到一個(gè)列表中也可以，那就裝箱成 object，然后多一個(gè)數(shù)組記錄第 i 個(gè)變量的類型，再轉(zhuǎn)回去，這樣效率就太低了，而且感覺很蠢
所以問題就是，當(dāng)我需要批量給一組變量插值的時(shí)候，我會(huì)寫出數(shù)量為 n 的插值語句和數(shù)量為 n 的緩存變量
那要解決這個(gè)問題的話，我目前只能想到是
比如 Vector3 就是 SwitchableVector3，float 就是 SwitchableFloat
以 SwitchableFloat 為例，它包含一個(gè) float Value，一個(gè) List<float> SwitchableValueList 和一個(gè) float SmoothVelocity
這樣，法一
偽代碼
// 法一float switchTime = 1f; float smoothTime = 0.2f;T0 V0; T0 velocity0;T1 V1; T1 velocity1;T2 V2; T2 velocity2;Setting setting0; Setting setting1; Setting setting2;Setting setting0 = {T0 V0;T1 V1;T2 V2; }Setting setting1 = {T0 V0;T1 V1;T2 V2; }Setting setting2 = {T0 V0;T1 V1;T2 V2; }Dictionary<EnumXXX, Setting> settingDictionary;void Start() { settingDictionary = new Dictionary<EnumXXX, Setting>{{0,setting0},{1,setting1},{2,setting2}}; }現(xiàn)在是
偽代碼
// 法二List<ISwitchable> switchableObjectList;SwitchableFloat V0; V0.SwitchableValueList = {float target0;float target1;float target2; }SwitchableVector2 V1; V1.SwitchableValueList = {Vector2 target0;Vector2 target1;Vector2 target2; }SwitchableVector3 V2; V2.SwitchableValueList = {Vector3 target0;Vector3 target1;Vector3 target2; }void Start() {switchableObjectList.Add(V0);switchableObjectList.Add(V1);switchableObjectList.Add(V2); }以前我需要
偽代碼
// 法一Enumator SwitchSettingCoroutine(EnumXXX mode) {float time = switchTime;while(time > 0){time -= Time.DeltaTime;V0 = Math.SmoothDamp(V0, settingDictionary[mode].V0, ref velocity0, smoothTime);V1 = Math.SmoothDamp(V1, settingDictionary[mode].V1, ref velocity1, smoothTime);V2 = Math.SmoothDamp(V2, settingDictionary[mode].V2, ref velocity2, smoothTime);}yield return null; }void SwitchSetting(EnumXXX mode) {StartCoroutine(SwitchSettingCoroutine(mode)); }現(xiàn)在我需要
偽代碼
// 法二Enumator SwitchSettingCoroutine(EnumXXX mode) {float time = switchTime;while(time > 0){time -= Time.DeltaTime;for(ISwitchable s in switchableObjectList)s.SwitchValue(mode);}yield return null; }void SwitchSetting(EnumXXX mode) {StartCoroutine(SwitchSettingCoroutine(mode)); }不知道我這樣寫行不行，會(huì)有什么問題……
這個(gè)看上去是很好的
一個(gè)數(shù)據(jù)表，假設(shè)行號(hào)是 Enum 列號(hào)是變量名
這樣做把數(shù)據(jù)表的每一列拆到每一個(gè)變量里面
但是實(shí)際上符合習(xí)慣的做法是一行一行的
如果我真的要把數(shù)據(jù)表的一行放到一起，比如放到 ScriptableObject 里面
那么我取變量的目標(biāo)值的流程就是：輸入一個(gè)變量，然后通過反射拿到這個(gè)變量的名字，然后根據(jù) Enum 在 字典 <Enum, Setting> 拿到 Setting，然后這個(gè) Setting 也是一個(gè) <string, 變量> 的字典，根據(jù)這個(gè)變量的名字在這個(gè)字典中拿到目標(biāo)值
但是這樣的話，這個(gè)函數(shù)有不同類型，Setting 中的字典也有不同類型，Setting 中還要寫一個(gè)初始化函數(shù)把目標(biāo)值放到不同類型的字典中
要不然就寫成 Setting 里面只有不同類型的字典，這樣就省去了初始化的麻煩
那么用的時(shí)候就是
偽代碼
// 法三private float value1; private Vector3 value2; private Vector2 value3; private Setting setting;private void GetTargetValueFromSetting() {string name;name = nameof(value1);float target = setting.GetFloatDict()[name];name = nameof(value2);Vector3 target = setting.GetVector3Dict()[name];name = nameof(value3);Vector2 target = setting.GetVector2Dict()[name]; }由于要獲取名字，所以不可避免寫 n 條語句……這就太麻煩了
偽代碼
// 法四public class SwitchableFloat : ISwitchable {public float value;public Dictionary<EnumXXX, float> targetValueDict;public override void SwitchValue(EnumXXX mode){float target = targetValueDict[mode];// SmoothDamp } }public interface ISwitchable {public void SwitchValue(EnumXXX mode); }public float switchTime; public SwitchableFloat value1; public SwitchableFloat value2; public SwitchableFloat value3; public List<ISwitchable> switchableObjectList;void Start() {switchableObjectList.Add(value1);switchableObjectList.Add(value2);switchableObjectList.Add(value3); }public IEnumerator SwitchSettingCoroutine(EnumXXX mode) {float time = switchTime;while(time > 0){time -= Time.deltaTime;for(ISwitchable s in switchableObjectList)s.SwitchValue(mode);}yield return null; }void SwitchSetting(EnumXXX mode) {StartCoroutine(SwitchSettingCoroutine(mode)); }我不用泛型一個(gè)原因是在監(jiān)視器上配置實(shí)現(xiàn)泛型的變量會(huì)出錯(cuò)，即使用了 Odin，另一個(gè)原因是 SmoothDamp 沒有泛型
跟我討論的朋友問我為什么不用 Animator，我說那是用來做骨骼動(dòng)畫的
但是后來我又想到 timeline，他是可以控制腳本的
首先的問題是我不知道怎么制作變量軌道
就算我知道了，變量軌道也需要一個(gè)確定的初值和終值，我這個(gè)是需要隨時(shí)切換狀態(tài)，比如按住右鍵瞄準(zhǔn)，他可能一會(huì)瞄準(zhǔn)一會(huì)不秒，切換時(shí)間小于動(dòng)畫時(shí)間，那么如果第一次動(dòng)畫時(shí)間，當(dāng)前值就是初值，第二次相反的退出瞄準(zhǔn)動(dòng)畫開始時(shí)，當(dāng)前值也不會(huì)是退出瞄準(zhǔn)動(dòng)畫的初值
除非我可以讓動(dòng)畫的初值為當(dāng)前值，或者我可以根據(jù)當(dāng)前值，動(dòng)畫的初值終值得到我應(yīng)該在哪個(gè)百分比進(jìn)度播放動(dòng)畫……
好吧我后面知道了 Playable Track 是可以自定義 Clip 的
好麻煩……不想看……我就是懶hhhh
而且按照我最后的法四，我可以在監(jiān)視器中對(duì)每一項(xiàng)變量設(shè)置對(duì)每一個(gè) mode 的可能值的目標(biāo)值，如果我不設(shè)置說明我就不用平滑這個(gè)變量
這是點(diǎn)開組件就能在監(jiān)視器中看到的，timeline 可不行
再化簡(jiǎn)一點(diǎn)就是
偽代碼
// 法四public class SwitchableFloat : ISwitchable {public float value;public Dictionary<EnumXXX, float> targetValueDict;public override void SwitchValue(EnumXXX mode){float target = targetValueDict[mode];// SmoothDamp } }public interface ISwitchable {public void SwitchValue(EnumXXX mode); }public float switchTime; public SwitchableFloat value1; public SwitchableFloat value2; public SwitchableFloat value3; public List<ISwitchable> switchableObjectList;private Coroutine switchSettingCoroutine;private EnumXXX mode;public EnumXXX Mode {get => mode;set{if (mode != value){if (switchSettingCoroutine != null)StopCoroutine(switchSettingCoroutine);switchSettingCoroutine = StartCoroutine(SwitchSettingCoroutine(value));mode = value;}} }void Start() {switchableObjectList.Add(value1);switchableObjectList.Add(value2);switchableObjectList.Add(value3); }public IEnumerator SwitchSettingCoroutine(EnumXXX mode) {float time = switchTime;while(time > 0){time -= Time.deltaTime;for(ISwitchable s in switchableObjectList)s.SwitchValue(mode);}yield return null; }2. Switchable v1

按照我最后的思路就是寫成

不能在外部替換類里面的屬性，那就只能用委托了
所以 SwitchableFloat 還要改

已經(jīng)改造過了 AnimationController，別的就是照葫蘆畫瓢
舊版 LocomotionController
可以說得上是最需要 Switchable 的了
你看這一開始寫了多少變量和 Smooth 語句出來，都是冗余的
