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，其实不看我上一篇文章都没发觉我的进程已经快了这么多啊，那么我就顺着上一篇文章开讲现在完成的场景转换系统吧。

顺便提醒，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、制作新的场景

1.重新翻新各种Sprite

        如果你还记得我之前讲过有关tk2dSpirte的时候，我的很多图都是直接PS扣下来的，因此不仅图像模糊，还可能会漏动画帧的情况，这里我们就对之前讲过的一些要用到的tk2dSpirte重新制作，步骤都是一样的，删除原本tk2dSpirte里面的sprite，把我们新搞到手的sprite拖进去然后commit提交，重新制作动画：

说个搞笑的我之前的waterdrip没扣干净会有马赛克，现在我们终于有了一手新的waterdrip的Sprite：

这个生命水之前也没有扣干净。。而且动画还很鬼畜，这下问题都解决了

然后再重新制作他们的动画就好了 

2.制作地图前期应该做的事情 

接下来就是要制作我们游戏主角的城镇德特茅斯，我们就创建一个新的场景名字就叫Town，添加场景后的第一件事情就是导入到Build Setting中：

然后我们就可以使用tk2dTilemap来制作地图基本的模样了：

 为了效率，我把Tilemap里面的Tile Properties的Size调整成64x64了，这样方便我们更快的画地图：

 3.疯狂的制作地图

有了这个tilemap我们很好的画出了一个地图基本的模样以及地图基本的碰撞框。你已经学会了怎么绘制一张图前期该做的事了，首先创建一个原点位置的游戏对象_Scenery,然后就是疯狂的制作，疯狂的堆叠素材，

        下面试着画出这样的地图吧：

对于城镇，我们少见的可交互对象只有草，还有NPC和几个房屋，但这些我都还没做到，所以我等着后面做UI的时候再着手制作吧。还有别忘了添加Directional Light让场景亮起来。

二、制作场景切换管理系统

1.制作场景切换点TransitionPoint

using System;
using System.Collections.Generic;
using GlobalEnums;
using UnityEngine;
using UnityEngine.Audio;public class TransitionPoint : MonoBehaviour
{private GameManager gm;private PlayerData playerData;private bool activated;[Header("Door Type Gate Settings")][Space(5f)]public bool isADoor; //是否是个门，意思是当你到传送点的时候还需要UI提示后按键输入才能触发转移public bool dontWalkOutOfDoor; //不要走出门[Header("Gate Entry")][Tooltip("The wait time before entering from this gate (not the target gate).")]public float entryDelay; //转移后的延迟public bool alwaysEnterRight; //进入这个转移点总是朝右看public bool alwaysEnterLeft; //进入这个转移点总是朝左看[Header("Force Hard Land (Top Gates Only)")][Space(5f)]public bool hardLandOnExit; //强制重着地[Header("Destination Scene")][Space(5f)]public string targetScene; //目标场景public string entryPoint; //进入的点public Vector2 entryOffset; //进入时的偏移量[SerializeField] private bool alwaysUnloadUnusedAssets;public PlayMakerFSM customFadeFSM; //自定义Fade的playmakerFSM[Header("Hazard Respawn")][Space(5f)]public bool nonHazardGate; //这个门不能用来做HazardRespawn的重生点public HazardRespawnMarker respawnMarker;[Header("Set Audio Snapshots")][Space(5f)]public AudioMixerSnapshot atmosSnapshot;public AudioMixerSnapshot enviroSnapshot;public AudioMixerSnapshot actorSnapshot;public AudioMixerSnapshot musicSnapshot;private Color myGreen = new Color(0f, 0.8f, 0f, 0.5f);private static List<TransitionPoint> transitionPoints;public static string lastEntered = ""; //记录最后进入的TransitionPointpublic delegate void BeforeTransitionEvent();public event BeforeTransitionEvent OnBeforeTransition;public static List<TransitionPoint> TransitionPoints{get{return transitionPoints;}}[RuntimeInitializeOnLoadMethod(RuntimeInitializeLoadType.BeforeSceneLoad)]private static void Init(){transitionPoints = new List<TransitionPoint>();}protected void Awake(){transitionPoints.Add(this);}protected void OnDestroy(){transitionPoints.Remove(this);}private void Start(){gm = GameManager.instance;playerData = PlayerData.instance;if(!nonHazardGate && respawnMarker == null){Debug.LogError(string.Concat(new string[]{"Transition Gate ",name," in ",gm.sceneName," does not have its respawn marker set in inspector."}));}}private void OnTriggerEnter2D(Collider2D movingObj){
//判断碰撞对象是否是Player的layerif(!isADoor && movingObj .gameObject.layer == 9 && gm.gameState == GameState.PLAYING){if(!string.IsNullOrEmpty(targetScene) && !string.IsNullOrEmpty(entryPoint)){if (customFadeFSM){customFadeFSM.SendEvent("FADE");}if (atmosSnapshot != null){atmosSnapshot.TransitionTo(1.5f);}if (enviroSnapshot != null){enviroSnapshot.TransitionTo(1.5f);}if (actorSnapshot != null){actorSnapshot.TransitionTo(1.5f);}if (musicSnapshot != null){musicSnapshot.TransitionTo(1.5f);}activated = true;lastEntered = gameObject.name;if (OnBeforeTransition != null){OnBeforeTransition();}return;}Debug.LogError(gm.sceneName + " " + name + " no target scene has been set on this gate.");}}private void OnTriggerStay2D(Collider2D movingObj){if (!activated){OnTriggerEnter2D(movingObj);}}private void OnDrawGizmos(){if (transform != null){Vector3 position = transform.position + new Vector3(0f, GetComponent<BoxCollider2D>().bounds.extents.y + 1.5f, 0f);GizmoUtility.DrawText(GUI.skin, targetScene, position, new Color?(myGreen), 10, 0f);}}/// <summary>/// 获取当前门的位置，请注意你的TransitionPoint名字一定要有如下字段/// </summary>/// <returns></returns>public GatePosition GetGatePosition(){string name = base.name;if (name.Contains("top")){return GatePosition.top;}if (name.Contains("right")){return GatePosition.right;}if (name.Contains("left")){return GatePosition.left;}if (name.Contains("bot")){return GatePosition.bottom;}if (name.Contains("door") || isADoor){return GatePosition.door;}Debug.LogError("Gate name " + name + "does not conform to a valid gate position type. Make sure gate name has the form 'left1'");return GatePosition.unknown;}public void SetTargetSceneName(string newScene){targetScene = newScene;}}

然后我们就要给TransitionPoint设置好对应的layer，以及什么能和这个layer发生碰撞检测：

 设置好对应的参数：

回到Town创建中我们也来创建对应的TransitionPoint:

 看到这里，你是否发现有什么不对劲？第一，你就给两个TransitionPoint，我的SceneManager.LoadScene()呢？关有转移点没有转移有嘛用，第二，你的Tutorial_01的转移点在那个门后面，游戏里面都是打了几下门直接就到了Town场景根本就不用走过去，这就引出了我们下面要介绍的切换场景时的脚本逻辑处理

2.切换场景时的脚本逻辑处理

不再是第一次玩游戏

 private void NoLongerFirstGame()
    {
    if (playerData.isFirstGame)
    {
        playerData.isFirstGame = false;
    }
    }

下面这个是这个要等到我们后续做到再实现的暂且TODO：

 public void SaveLevelState()
    {
    //TODO:
    }

回到GlobalEnum创建好数组记录当前游戏状态：

public enum GameState{INACTIVE, //非活跃MAIN_MENU, //主菜单LOADING, //加载ENTERING_LEVEL, //进入场景PLAYING, //游玩PAUSED, //暂停EXITING_LEVEL, //里面场景CUTSCENE, //过场PRIMER //先前的}

 再回到GameManager.cs中：

public void SetState(GameState newState)
    {
    gameState = newState;
    }

当激活完成后，我们就可以用到我们熟悉的UnityEngine.SceneManagement.SceneManager.UnloadScene(lastSceneName);这个是卸载当前的创建，方法RefreshTilemapInfo(string targetScene)是用来重新获取新场景的tk2dtilemap，如果你看过我们上一期就知道这个tk2dtilemap用来获取每一个场景的宽度和高度：

/// <summary>/// 重新刷新场景的tilemap的信息/// </summary>/// <param name="targetScene"></param>public void RefreshTilemapInfo(string targetScene){if (IsNonGameplayScene()){return;}tk2dTileMap tk2dTileMap = null;int num = 0;while (tk2dTileMap == null && num < UnityEngine.SceneManagement.SceneManager.sceneCount){Scene sceneAt = UnityEngine.SceneManagement.SceneManager.GetSceneAt(num);if (string.IsNullOrEmpty(targetScene) || !(sceneAt.name != targetScene)){GameObject[] rootGameObjects = sceneAt.GetRootGameObjects();int num2 = 0;while (tk2dTileMap == null && num2 < rootGameObjects.Length){tk2dTileMap = GetTileMap(rootGameObjects[num2]);num2++;}}num++;}if (tk2dTileMap == null){Debug.LogErrorFormat("Using fallback 1 to find tilemap. Scene {0} requires manual fixing.", new object[]{targetScene});GameObject[] array = GameObject.FindGameObjectsWithTag("TileMap");int num3 = 0;while (tk2dTileMap == null && num3 < array.Length){tk2dTileMap = array[num3].GetComponent<tk2dTileMap>();num3++;}}if (tk2dTileMap == null){Debug.LogErrorFormat("Using fallback 2 to find tilemap. Scene {0} requires manual fixing.", new object[]{targetScene});GameObject gameObject = GameObject.Find("TileMap");if (gameObject != null){tk2dTileMap = GetTileMap(gameObject);}}if (tk2dTileMap == null){Debug.LogErrorFormat("Failed to find tilemap in {0} entirely.", new object[]{targetScene});return;}tilemap = tk2dTileMap;sceneWidth = tilemap.width;sceneHeight = tilemap.height;}private static tk2dTileMap GetTileMap(GameObject gameObject){if (gameObject.CompareTag("TileMap")){return gameObject.GetComponent<tk2dTileMap>();}return null;}

重新获取场景引用SetupSceneRefs：

 public void SetupSceneRefs(bool refreshTilemapInfo){UpdateSceneName();if(ui == null){ui = UIManager.instance;}GameObject gameObject = GameObject.FindGameObjectWithTag("SceneManager");if(gameObject != null){sm = gameObject.GetComponent<SceneManager>();}else{Debug.Log("Scene Manager missing from scene " + sceneName);}if (IsGameplayScene()){if (hero_ctrl == null){SetupHeroRefs();}if (refreshTilemapInfo){RefreshTilemapInfo(sceneName);}}}private void SetupHeroRefs(){hero_ctrl = HeroController.instance;}

 还有开启场景后需要做的事情BeginScene：

 public void BeginScene(){inputHandler.SceneInit();if (hero_ctrl){hero_ctrl.SceneInit();}gameCams.SceneInit();if (IsMenuScene()){SetState(GameState.MAIN_MENU);UpdateUIStateFromGameState();return;}if (IsGameplayScene()){if ((!Application.isEditor && !Debug.isDebugBuild) || Time.renderedFrameCount > 3){PositionHeroAtSceneEntrance();}if(sm != null){return;}}else{if (IsNonGameplayScene()){SetState(GameState.CUTSCENE);UpdateUIStateFromGameState();return;}Debug.LogError("GM - Scene type is not set to a standard scene type.");UpdateUIStateFromGameState();}}

我们通过场景名字来判断当前是什么类型的场景：

public bool IsMenuScene(){UpdateSceneName();return sceneName == "Menu_Title";}public bool IsGameplayScene(){UpdateSceneName();return !IsNonGameplayScene();}public bool IsNonGameplayScene(){return IsCinematicScene() || sceneName == "Knight Pickup" || sceneName == "Pre_Menu_Intro" || sceneName == "Menu_Title" || sceneName == "End_Credits" || sceneName == "Menu_Credits" || sceneName == "Cutscene_Boss_Door" || sceneName == "PermaDeath_Unlock" || sceneName == "GG_Unlock" || sceneName == "GG_End_Sequence" || sceneName == "End_Game_Completion" || sceneName == "BetaEnd" || sceneName == "PermaDeath" || sceneName == "GG_Entrance_Cutscene" || sceneName == "GG_Boss_Door_Entrance";}public bool IsCinematicScene(){UpdateSceneName();return sceneName == "Intro_Cutscene_Prologue" || sceneName == "Opening_Sequence" || sceneName == "Prologue_Excerpt" || sceneName == "Intro_Cutscene" || sceneName == "Cinematic_Stag_travel" || sceneName == "PermaDeath" || sceneName == "Cinematic_Ending_A" || sceneName == "Cinematic_Ending_B" || sceneName == "Cinematic_Ending_C" || sceneName == "Cinematic_Ending_D" || sceneName == "Cinematic_Ending_E" || sceneName == "Cinematic_MrMushroom" || sceneName == "BetaEnd";}private void UpdateSceneName(){sceneName = GetBaseSceneName(UnityEngine.SceneManagement.SceneManager.GetActiveScene().name);}

 还需要让下一场景的内容做好准备OnNextLevelReady：

public void OnNextLevelReady(){if (IsGameplayScene()){SetState(GameState.ENTERING_LEVEL);playerData.disablePause = false;inputHandler.AllowPause();inputHandler.StartAcceptingInput();Debug.LogFormat("OnNextLevelReady entryGateName =" + entryGateName);EnterHero(true);}}

角色进入EnterHero():

 public void EnterHero(bool additiveGateSearch = false){if (RespawningHero){StartCoroutine(hero_ctrl.Respawn());FinishedEnteringScene();RespawningHero = false;return;}if (hazardRespawningHero){StartCoroutine(hero_ctrl.HazardRespawn());FinishedEnteringScene();hazardRespawningHero = false;return;}if (startedOnThisScene){if (IsGameplayScene()){FinishedEnteringScene();FadeSceneIn();}return;}SetState(GameState.ENTERING_LEVEL);if (string.IsNullOrEmpty(entryGateName)){Debug.LogError("No entry gate has been defined in the Game Manager, unable to move hero into position.");FinishedEnteringScene();return;}if (additiveGateSearch){Debug.Log("Searching for entry gate " + entryGateName + " !in the next scene: " + nextSceneName);foreach (GameObject gameObject in UnityEngine.SceneManagement.SceneManager.GetSceneByName(nextSceneName).GetRootGameObjects() ){TransitionPoint component = gameObject.GetComponent<TransitionPoint>();if(component != null && component.name == entryGateName){Debug.Log("SUCCESS - Found as root object");StartCoroutine(hero_ctrl.EnterScene(component, entryDelay));return;}if(gameObject.name == "_Transition Gates"){TransitionPoint[] componentsInChildren = gameObject.GetComponentsInChildren<TransitionPoint>();for (int i = 0; i < componentsInChildren.Length; i++){if(componentsInChildren[i].name == entryGateName){Debug.Log("SUCCESS - Found in _Transition Gates folder");StartCoroutine(hero_ctrl.EnterScene(componentsInChildren[i], entryDelay));return;}}}TransitionPoint[] componentsInChildren2 = gameObject.GetComponentsInChildren<TransitionPoint>();for (int j = 0; j < componentsInChildren2.Length; j++){if (componentsInChildren2[j].name == entryGateName){Debug.Log("SUCCESS - Found in _Transition Gates folder");StartCoroutine(hero_ctrl.EnterScene(componentsInChildren2[j], entryDelay));return;}}}Debug.LogError("Searching in next scene for TransitionGate failed.");return;}GameObject gameObject2 = GameObject.Find(entryGateName);if(gameObject2 != null){TransitionPoint component2 = gameObject2.GetComponent<TransitionPoint>();StartCoroutine(hero_ctrl.EnterScene(component2, entryDelay));return;}Debug.LogError(string.Concat(new string[]{"No entry point found with the name \"",entryGateName,"\" in this scene (",sceneName,"). Unable to move hero into position, trying alternative gates..."}));TransitionPoint[] array = FindObjectsOfType<TransitionPoint>();if(array != null){StartCoroutine(hero_ctrl.EnterScene(array[0], entryDelay));return;}Debug.LogError("Could not find any gates in this scene. Trying last ditch spawn...");hero_ctrl.transform.SetPosition2D(tilemap.width / 2f, tilemap.height / 2f);}public void FinishedEnteringScene(){SetState(GameState.PLAYING);entryDelay = 0f;hasFinishedEnteringScene = true;if (OnFinishedSceneTransition != null){OnFinishedSceneTransition();}}public void FadeSceneIn(){cameraCtrl.FadeSceneIn();}

 回到HeroController.cs中，首先我们要制作玩家离开创建时的行为：

 public void LeaveScene(GatePosition? gate = null){isHeroInPosition = false;IgnoreInputWithoutReset();ResetHardLandingTimer();SetState(ActorStates.no_input);SetDamageMode(DamageMode.NO_DAMAGE);transitionState = HeroTransitionState.EXITING_SCENE;CancelFallEffects();tilemapTestActive = false;SetHeroParent(null);StopTilemapTest();if(gate != null){switch (gate.Value){case GatePosition.top:transition_vel = new Vector2(0f, MIN_JUMP_SPEED);cState.onGround = false;break;case GatePosition.right:transition_vel = new Vector2(RUN_SPEED, 0f);break;case GatePosition.left:transition_vel = new Vector2(-RUN_SPEED, 0f);break;case GatePosition.bottom:transition_vel = Vector2.zero;cState.onGround = false;break;}}cState.transitioning = true;}

然后我们来制作一个协程处理进入场景：

     private bool stopWalkingOut;public float TIME_TO_ENTER_SCENE_BOT;public float TIME_TO_ENTER_SCENE_HOR;public float SPEED_TO_ENTER_SCENE_HOR;public float SPEED_TO_ENTER_SCENE_UP;public float

来到GlobalEnum添加好角色转移的状态：

 public enum HeroTransitionState{WAITING_TO_TRANSITION,EXITING_SCENE,WAITING_TO_ENTER_LEVEL,ENTERING_SCENE,DROPPING_DOWN}

 找到落地点：

 public Vector3 FindGroundPoint(Vector2 startPoint,bool useExtended = false){float num = FIND_GROUND_POINT_DISTANCE;if (useExtended){num = FIND_GROUND_POINT_DISTANCE_EXT;}RaycastHit2D raycastHit2D = Physics2D.Raycast(startPoint, Vector2.down, num, LayerMask.GetMask("Terrain"));if(raycastHit2D.collider == null){Debug.LogErrorFormat("FindGroundPoint: Could not find ground point below {0}, check reference position is not too high (more than {1} tiles).", new object[]{startPoint.ToString(),num});}return new Vector3(raycastHit2D.point.x, raycastHit2D.point.y + col2d.bounds.extents.y - col2d.offset.y + 0.01f, transform.position.z);}private float FindGroundPointY(float x, float y, bool useExtended = false){float num = FIND_GROUND_POINT_DISTANCE;if (useExtended){num = FIND_GROUND_POINT_DISTANCE_EXT;}RaycastHit2D raycastHit2D = Physics2D.Raycast(new Vector2(x, y), Vector2.down, num, LayerMask.GetMask("Terrain"));if (raycastHit2D.collider == null){Debug.LogErrorFormat("FindGroundPoint: Could not find ground point below ({0},{1}), check reference position is not too high (more than {2} tiles).", new object[]{x,y,num});}return raycastHit2D.point.y + col2d.bounds.extents.y - col2d.offset.y + 0.01f;}

 还有我么上期降到的：

 private void FinishedEnteringScene(bool setHazardMarker = true, bool preventRunBob = false){if(isEnteringFirstLevel){isEnteringFirstLevel = false;}else{playerData.disablePause = false;}cState.transitioning = false;transitionState = HeroTransitionState.WAITING_TO_TRANSITION;stopWalkingOut = false;SetStartingMotionState(preventRunBob);AffectedByGravity(true);if (setHazardMarker){if (sceneEntryGate == null){playerData.SetHazardRespawn(transform.position, cState.facingRight);}else if (!sceneEntryGate.nonHazardGate){playerData.SetHazardRespawn(sceneEntryGate.respawnMarker);}}SetDamageMode(DamageMode.FULL_DAMAGE);if (enterWithoutInput){enterWithoutInput = false;}else{AcceptInput();}gm.FinishedEnteringScene();positionHistory[0] = transform.position;positionHistory[1] = transform.position;tilemapTestActive = true;}

至此我们制作了完整的切换创建的脚本逻辑处理，但还有一个问题没解决，那就是上面将的如何打完门直接场景转换呢？

当然使用到我们的playmaker了！

如果是激活状态，我们就直接销毁它，但这个要到我们后面做到可持续化数据才能用到 

检查攻击者的类型，也就是骨钉攻击 

 为玩家创建新的方法EnterWithoutInput()：

 public void EnterWithoutInput(bool flag){enterWithoutInput = flag;}

然后就是自定义playmakerFSM：我们还是用到了GameManager的BeginSceneTransition()方法

using UnityEngine;namespace HutongGames.PlayMaker.Actions
{[ActionCategory("Game Manager")][Tooltip("Perform a generic scene transition.")]public class BeginSceneTransition : FsmStateAction{public FsmString sceneName;public FsmString entryGateName;public FsmFloat entryDelay;[ObjectType(typeof(GameManager.SceneLoadVisualizations))]public FsmEnum visualization;public bool preventCameraFadeOut;public override void Reset(){sceneName = "";entryGateName = "left1";entryDelay = 0f;visualization = new FsmEnum{Value = GameManager.SceneLoadVisualizations.Default};preventCameraFadeOut = false;}public override void OnEnter(){GameManager unsafeInstance = GameManager.instance;if (unsafeInstance == null){LogError("Cannot BeginSceneTransition() before the game manager is loaded.");}else{unsafeInstance.BeginSceneTransition(new GameManager.SceneLoadInfo{SceneName = sceneName.Value,EntryGateName = entryGateName.Value,EntryDelay = entryDelay.Value,Visualization = (GameManager.SceneLoadVisualizations)visualization.Value,PreventCameraFadeOut = true,WaitForSceneTransitionCameraFade = !preventCameraFadeOut,AlwaysUnloadUnusedAssets = false});}Finish();}}}

总结

最后我们来看看效果吧

上面的UI是我后面做的先别管：

然后黑屏

 到达Town：

OK能移动还没有Error，完成。
