Unity使用OffMesh-Link时匹配动画动作

正常Unity的OffmeshLink是嗖的一下传送过去，如果要想在这里用自己的动画动作跳跃过去的方法如下，主要是知道Unity的一些相关API的使用方法。

下面是一些重要的API或数据结构：

_navAgent.autoTraverseOffMeshLink = false; //in Start()，设置不要自动进行Offmeh的传送
_navAgent.currentOffMeshLinkData; //the link data - this contains start and end points, etc
_navAgent.CompleteOffMeshLink(); //Tell unity we have traversed the link (do this when you've moved the transform to the end point)
_navAgent.Resume(); //Resume normal navmesh behaviour

代码示例如下：

using UnityEngine;[RequireComponent(typeof(NavMeshAgent))]
public class NavMeshAnimator : MonoBehaviour
{private NavMeshAgent _navAgent;private bool _traversingLink;private OffMeshLinkData _currLink;void Start(){// Cache the nav agent and tell unity we will handle link traversal_navAgent = GetComponent<NavMeshAgent>();_navAgent.autoTraverseOffMeshLink = false;}void Update(){//don't do anything if the navagent is disabledif (!_navAgent.enabled) return;if (_navAgent.isOnOffMeshLink){if (!_traversingLink){//This is done only once. The animation's progress will determine link traversal.animation.CrossFade("Jump", 0.1f, PlayMode.StopAll);//cache current link_currLink = _navAgent.currentOffMeshLinkData;//start traversing_traversingLink = true;}//lerp from link start to link end in time to animationvar tlerp = animation["Jump"].normalizedTime;//straight line from startlink to endlinkvar newPos = Vector3.Lerp(_currLink.startPos, _currLink.endPos, tlerp);//add the 'hop'newPos.y += 2f * Mathf.Sin(Mathf.PI * tlerp);//Update transform positiontransform.position = newPos;// when the animation is stopped, we've reached the other side. Don't use looping animations with this control setupif (!animation.isPlaying){//make sure the player is right on the end linktransform.position = _currLink.endPos;//internal logic reset_traversingLink = false;//Tell unity we have traversed the link_navAgent.CompleteOffMeshLink();//Resume normal navmesh behaviour_navAgent.Resume();}}else{//...update walk/idle animations appropriately ...etc
