我在试着创造一个游荡的人工智能
我正在使用unity standard assets第三人称人工智能
但问题是人工智能只是移动到某个点，它不能
在这些地点之间巡逻
这是密码？
如何修改为巡逻？
using System;
using UnityEngine;
namespace UnityStandardAssets.Characters.ThirdPerson
{
[RequireComponent(typeof (UnityEngine.AI.NavMeshAgent))]
[RequireComponent(typeof (ThirdPersonCharacter))]
public class AICharacterControl : MonoBehaviour
{
public UnityEngine.AI.NavMeshAgent agent { get; private set; } // the navmesh agent required for the path finding
public ThirdPersonCharacter character { get; private set; } // the character we are controlling
public Transform target; // target to aim for
private void Start()
{
// get the components on the object we need ( should not be null due to require component so no need to check )
agent = GetComponentInChildren();
character = GetComponent();
agent.updateRotation = false;
agent.updatePosition = true;
}
private void Update()
{
if (target != null)
agent.SetDestination(target.position);
if (agent.remainingDistance > agent.stoppingDistance)
character.Move(agent.desiredVelocity, false, false);
else
character.Move(Vector3.zero, false, false);
}
public void SetTarget(Transform target)
{
this.target = target;
}
}
}
要让人工智能在两点之间巡逻，你需要定义第二个点，并改变人工智能的行为，当它到达第一个点时改变目标。目前，一旦它到达目标（即停止），它将简单地以零速度移动。
不需要过多地修改代码，您可以通过这样做将其扩展为在两个位置之间移动。
using System;
using UnityEngine;
namespace UnityStandardAssets.Characters.ThirdPerson
{
[RequireComponent(typeof (UnityEngine.AI.NavMeshAgent))]
[RequireComponent(typeof (ThirdPersonCharacter))]
public class AICharacterControl : MonoBehaviour
{
public UnityEngine.AI.NavMeshAgent agent { get; private set; } // the navmesh agent required for the path finding
public ThirdPersonCharacter character { get; private set; } // the character we are controlling
public Transform start;
public Transform end;
private Transform target;
private boolean forward = true;
private void Start()
{
// get the components on the object we need ( should not be null due to require component so no need to check )
agent = GetComponentInChildren<UnityEngine.AI.NavMeshAgent>();
character = GetComponent<ThirdPersonCharacter>();
agent.updateRotation = false;
agent.updatePosition = true;
}
private void Update()
{
if (target != null)
agent.SetDestination(target.position);
if (agent.remainingDistance > agent.stoppingDistance)
{
character.Move(agent.desiredVelocity, false, false);
}
else
{
SetTarget(forward ? start : end);
forward = !forward;
}
}
public void SetTarget(Transform target)
{
this.target = target;
}
}
}
正如您所看到的，我修改了update()，告诉AI如果太接近当前目标就改变目标。在顶部还有一个额外的转换定义(start)需要设置，还有一个boolean用来存储AI的方向。
这段代码还没有在Unity中测试过，所以可能需要一些修改，但它应该会给你正确的想法。
