Standard Asset AI Third Person not working.

Questions & Answers

Hi,

I’m using the AI Third Person Character include in the Standard Assets. I am using the character as the enemy for the Standard Asset FPS Character which is currently working fine. The error I get is

  1. GetRemainingDistance" can only be called on an active agent that has been placed on a NavMesh.
    UnityEngine.NavMeshAgent:get_remainingDistance()

  2. SetDestination" can only be called on an active agent that has been placed on a NavMesh.
    UnityEngine.NavMeshAgent:SetDestination(Vector3)

I will attach the script used by this AI character. Pls take a look a it and give me your suggestions.

using System;
using UnityEngine;
using System.Collections;

namespace UnityStandardAssets.Characters.ThirdPerson
{

[RequireComponent(typeof(NavMeshAgent))]
[RequireComponent(typeof(ThirdPersonCharacter))]
public class AICharacterControl : MonoBehaviour
{
    public 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<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
            character.Move(Vector3.zero, false, false);
    }

    public void SetTarget(Transform target)
    {
        this.target = target;
    }
}

}

Cheers,
