骑马系统

人物在马上的脚本

using MalbersAnimations; using System.Collections; using System.Collections.Generic; using UnityEngine;  public class ThirdPersonRidingHorse : MonoBehaviour {     [Header("骑马参数")]     public GameObject horse;     public bool isOnHorse;      //void OnInteract()     //{     //    var thirdPersonMove = GetComponent<ThirdPersonMove>();     //    thirdPersonMove.enabled = false;     //    var pos = horse.transform.Find("Pos_UpToHorse");      //}      CharacterController characterController;     Animator animator;     ThirdPersonMove thirdPersonMove;      private void Awake()     {         characterController = GetComponent<CharacterController>();         animator = GetComponent<Animator>();         thirdPersonMove = GetComponent<ThirdPersonMove>();     }      private void Update()     {         if (isOnHorse)         {             var axisX = Input.GetAxis("Horizontal");             var axisY = Input.GetAxis("Vertical");             animator.SetFloat("AxisX", axisX);             animator.SetFloat("AxisY", axisY);         }         Ride();     }      void Ride()     {         //上马         if (!isOnHorse)         {             if (Input.GetKeyDown(KeyCode.F))             {                 isOnHorse = true;                 transform.rotation = horse.transform.rotation;                 transform.position = horse.transform.position;                 //将角色放到马上                 var playerPoint = horse.transform.Find("PlayerPoint");                 transform.SetParent(playerPoint);                 transform.localPosition = Vector3.zero;                 //在马上禁用角色的characterController和move                 characterController.enabled = false;                 thirdPersonMove.enabled = false;                 //开启马的输入控制脚本                 horse.GetComponent<MalbersInput>().enabled = true;                  //切换马上动作状态,即权重从0到1                 animator.SetLayerWeight(2, 1f);             }         }         //下马         else         {             if (Input.GetKeyDown(KeyCode.F))             {                 isOnHorse = false;                 if (horse != null)                 {                     //删除马之前设置角色位置                     transform.SetParent(null);                     transform.position = horse.transform.position;                     transform.rotation = horse.transform.rotation;                     //下马后恢复角色的characterController和move                     characterController.enabled = true;                     thirdPersonMove.enabled = true;                     //关闭马的输入控制脚本                     horse.GetComponent<MalbersInput>().enabled = false;                     //关闭马上动作层                     animator.SetLayerWeight(2, 0f);                  }             }         }      } }

状态机设置

先学习怎么做场景交互

以常见的开宝箱交互为例：

1）先建一个可开盖宝箱的模型

2）在Box的子级中建立一个空的GameObject，当作角色开始播放交互动画的位置

3）在Box的animation窗口中建立动画——Box的开盖动画

4）这里需要把开盖动画的Loop Time给取消勾选

5）来到Timeline窗口，新建一个Box的Timeline，把Box的开盖动画和角色交互的动画拖进去

注：角色动画是mixamo里找的

角色的Track在k帧的时候选上角色的animator，在k完之后就记得要取消勾选animator

也要记得修改该动画的名字，后面脚本会用到

为了保证开盖动画在人物动画播完后仍然还在播，点开开盖动画的Animation Track，设置为continue

6）把人物移到和PlayerStandPosition同一个位置，追求完美可以k一下开盖动画和角色动画的匹配度，并加上过渡动画(这里我就懒得弄了，因为只是学习怎么做动画交互系统)

7）为Box加上Tag-Box

8）为Box加上Trigger碰撞体

9）取消勾选Play On Awake，不然还没触发就开始播动画了

OK，交互动画匹配好了，下面写脚本控制角色到达一个Box周围的Trigger碰撞体区域，按下交互的Input按键才触发动画

脚本逻辑：

在碰撞体区域按下按键->开始找tag为Box的GameObject，找到的对象就是Box->在Box的子级中找名为PlayerStandPosition的对象->更新角色位置、朝向->在Box的playerableAsset中找到PlayerTrack，播放相应的BoxTimeline

脚本如下：

PlayerOpenBox.cs

using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.Playables; using UnityEngine.InputSystem;  public class PlayerOpenBox : MonoBehaviour {     bool isPlaying = false;      IEnumerator OnInteract()     {         if (list.Count > 0 && isPlaying == false)         {             isPlaying = true;              var thirdPersonMove = GetComponent<ThirdPersonMove>();             thirdPersonMove.enabled = false;             var thirdPersonJump = GetComponent<ThirdPersonJump>();             thirdPersonJump.enabled = false;             var thirdPersonRoll = GetComponent<ThirdPersonRoll>();             thirdPersonRoll.enabled = false;              var director = list[0];             list.RemoveAt(0);             var pos = director.transform.Find("PlayerStandPosition");             transform.position = pos.position;             //Debug.Log(pos.position);             transform.rotation = pos.rotation;             var animator = GetComponent<Animator>();             foreach (var output in director.playableAsset.outputs)             {                 if (output.streamName == "PlayerTrack")                 {                     director.SetGenericBinding(output.sourceObject, animator);                     break;                 }             }             director.Play();             while(director.state == PlayState.Playing)             {                 yield return null;             }             thirdPersonMove.enabled = true;             thirdPersonJump.enabled = true;             thirdPersonRoll.enabled = true;             isPlaying = false;         }     }        List<PlayableDirector> list = new List<PlayableDirector>();     private void OnTriggerEnter(Collider other)     {         if (other.gameObject.tag == "Box")         {             var director = other.gameObject.GetComponent<PlayableDirector>();             if (director != null && !list.Contains(director))             {                 list.Add(director);             }             //Debug.Log(transform.position);         }     }        private void OnTriggerExit(Collider other)     {         if (other.gameObject.tag == "Box")         {             var director = other.gameObject.GetComponent<PlayableDirector>();             if (director != null && list.Contains(director))             {                 list.Remove(director);             }         }     }    }

脚本挂在角色身上

效果如下：
