1、Off Mesh Link 过渡动画设置

首先创建一个动画
关闭 Nav Mesh Agent 中的 Auto Traverse Off Mesh Link

编写脚本

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.AI;public class OffMeshTest : MonoBehaviour
{//Playerpublic NavMeshAgent agent;//跳跃动画public Animation ani;//是否正在传送bool isTransfering;//传送目标OffMeshLinkData omld;void Update(){// 检测是否处于OffMeshLink上if(agent.isOnOffMeshLink){if(!isTransfering)   //未开始传送{ani.Play("offmeshAni");omld = agent.currentOffMeshLinkData;isTransfering = true;   }else                //开始传送{ // 获取动画的归一化进度（0到1之间）float timeLerp = ani["offmeshAni"].normalizedTime;// 计算线性插值位置（从起点到终点）var posLerp = Vector3.Lerp(omld.startPos, omld.endPos, timeLerp);// 添加Y轴的正弦曲线运动，模拟跳跃抛物线posLerp.y+= Mathf.Sin(timeLerp * Mathf.PI) * 2;if(!ani.isPlaying)    //动画停止播放{agent.transform.position = omld.endPos;isTransfering = false;// 完成OffMeshLink过渡agent.CompleteOffMeshLink();}}}}
}

2、Navigation Area导航区域成本设置

成本设置——代码实现：

1）修改 door 的成本

2）Area Mask

代码实现：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.AI;public class NavAreaTest : MonoBehaviour
{//Playerpublic NavMeshAgent agent;void Update(){if (Input.GetKeyDown(KeyCode.T)){NavMesh.SetAreaCost(NavMesh.GetAreaFromName("Door"), 10000.0f);}if(Input.GetKeyDown(KeyCode.M)){int walkable = 1 << NavMesh.GetAreaFromName("Walkable");int jump= 1 << NavMesh.GetAreaFromName("Jump");int door = 1 << NavMesh.GetAreaFromName("Door");agent.areaMask = walkable + jump+ door;}}
}

3、多导航场景叠加跳转

实现代码：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.AI;
using UnityEngine.SceneManagement;public class Test : MonoBehaviour
{public OffMeshLink oml;GameObject linkGo;void Update(){if (Input.GetKeyDown(KeyCode.A)){//  Scene加载模式 为 叠加 LoadSceneMode.Additive (两个Scenes同时出现)SceneManager.LoadScene("SceneAdd2", LoadSceneMode.Additive);}if (Input.GetKeyDown(KeyCode.B)){linkGo = GameObject.FindGameObjectWithTag("Link");oml.endTransform = linkGo.transform;}}
}
