很多时候我们需要做类似上图的OffMeshLink的跳跃功能，并方便添加跳跃动画，Unity本身没提供，但是有官方的案例提供了方法，很多人没找到，故贴出来

原链接：https://github.com/Unity-Technologies/NavMeshComponents/blob/master/Assets/Examples/Scripts/AgentLinkMover.cs

我在它的基础上添加了两个多播委托及快速转向（红字显示），用来检测跳跃开始及结束，方便用来做跳跃动画的，而且NavMeshAgentde转速太慢，我添加一个快速转向到落地点的方法。

用不到的就用原版吧。

      ();        agent.autoTraverseOffMeshLink = false;        while (true)        {            if (agent.isOnOffMeshLink)            {                                yield return StartCoroutine (FaceToTarget (agent, FaceTime));                if (method == OffMeshLinkMoveMethod.NormalSpeed)                    yield return StartCoroutine(NormalSpeed(agent));                else if (method == OffMeshLinkMoveMethod.Parabola)                    yield return StartCoroutine(Parabola(agent, 2.0f, 0.5f));                else if (method == OffMeshLinkMoveMethod.Curve)                    yield return StartCoroutine(Curve(agent, CurveTime));                agent.CompleteOffMeshLink();                agent.updateRotation = true;                OnComplete ();            }            yield return null;        }    }    IEnumerator FaceToTarget(NavMeshAgent agent,float duration){        agent.updateRotation = false;        OffMeshLinkData data = agent.currentOffMeshLinkData;        Quaternion startRotation = agent.transform.rotation;        Vector3 endPos = data.endPos + Vector3.up * agent.baseOffset;        var endRotation = Quaternion.LookRotation (new Vector3 (endPos.x - agent.transform.position.x, 0, endPos.z - transform.position.z));        float normalizedTime = 0.0f;        while (normalizedTime < 1.0f)        {            agent.transform.rotation = Quaternion.Slerp(startRotation ,endRotation ,normalizedTime);            normalizedTime += Time.deltaTime / duration;            yield return null;        }        OnStart ();    }    IEnumerator NormalSpeed(NavMeshAgent agent)    {        OffMeshLinkData data = agent.currentOffMeshLinkData;        Vector3 endPos = data.endPos + Vector3.up * agent.baseOffset;        while (agent.transform.position != endPos)        {            agent.transform.position = Vector3.MoveTowards(agent.transform.position, endPos, agent.speed * Time.deltaTime);            yield return null;        }    }    IEnumerator Parabola(NavMeshAgent agent, float height, float duration)    {        OffMeshLinkData data = agent.currentOffMeshLinkData;        Vector3 startPos = agent.transform.position;        Vector3 endPos = data.endPos + Vector3.up * agent.baseOffset;        float normalizedTime = 0.0f;        while (normalizedTime < 1.0f)        {            float yOffset = height * 4.0f * (normalizedTime - normalizedTime * normalizedTime);            agent.transform.position = Vector3.Lerp(startPos, endPos, normalizedTime) + yOffset * Vector3.up;            normalizedTime += Time.deltaTime / duration;            yield return null;        }    }    IEnumerator Curve(NavMeshAgent agent, float duration)    {        OffMeshLinkData data = agent.currentOffMeshLinkData;        Vector3 startPos = agent.transform.position;        Vector3 endPos = data.endPos + Vector3.up * agent.baseOffset;        float normalizedTime = 0.0f;        while (normalizedTime < 1.0f)        {            float yOffset = curve.Evaluate(normalizedTime);            agent.transform.position = Vector3.Lerp(startPos, endPos, normalizedTime) + yOffset * Vector3.up;            normalizedTime += Time.deltaTime / duration;            yield return null;        }    }}
     

 

用法，附着到NavMeshAgent物体上，选择需要的移动方式即可，然后搭配一下代码食用更佳：

AgentLinkMover mover = GetComponent
     
      ();mover.OnStart += () => print("start");mover.OnComplete += () => print("complete");
