多NavMesh Agent共存时部分Agent卡顿无法移动问题求助

核心逻辑代码 #

撤退触发方法：

public void StartRetreating()
{
    animator.SetBool("Attack", false);
    isRetreating = true;
    StartCoroutine(Retreat());
}

辅助方法与协程：

private Vector3 GetRandomPointAroundPlayer(Vector3 center, float radius)
{
    Vector3 randomDirection = Random.insideUnitSphere * radius;
    randomDirection.y = 0f;
    Vector3 randomPoint = center + randomDirection;

    NavMeshHit hit;
    if (NavMesh.SamplePosition(randomPoint, out hit, radius, NavMesh.AllAreas))
    {
        return hit.position;
    }

    // 未找到有效位置时返回原中心
    return center;
}

IEnumerator Retreat()
{
    yield return new WaitForSeconds(0.5f);
    animator.SetBool("Walk", false);
    wanderTarget = GetRandomPointAroundPlayer(enemySight.player.transform.position, wanderRadius);
    Collider[] colliders = Physics.OverlapSphere(wanderTarget, 3f); // 可调整半径
    foreach (Collider collider in colliders)
    {
        if (collider.CompareTag("RetreatPoint"))
        {
            // 附近有撤退点，重新获取随机目标
            wanderTarget = GetRandomPointAroundPlayer(enemySight.player.transform.position, wanderRadius);
        }
    }
    Walk(wanderTarget);
}

void Walk(Vector3 wanderTarget)
{
    if (canSpawnRetreatPoint)
    {
        retreatObject=Instantiate(retreatPoint, new(wanderTarget.x, -2, wanderTarget.z), Quaternion.identity);
        canSpawnRetreatPoint = false;
    }
    if (enemySight.playerOnRight == true && enemyWalk.facingRight == true)
    {
        enemyWalk.Flip();
    }
    else if (enemySight.playerOnRight == false && !enemyWalk.facingRight)
    {
        enemyWalk.Flip();
    }
    navMeshAgent.speed = enemyWalk.enemySpeed; // 同步NavMesh速度与敌人行走速度
    enemyWalk.enemyCurrentSpeed = navMeshAgent.velocity.sqrMagnitude;
    navMeshAgent.SetDestination(wanderTarget); // 设置移动目标
    navMeshAgent.updateRotation = false; // 防止敌人Sprite旋转
}

异常现象 #

• 1-2个Agent时功能正常，增加到4个时，至少有一个Agent卡在行走/撤退状态：行走动画播放，但Agent无法移动。
• 撤退点带有触发器，拖拽Agent到撤退点时，触发器正常触发状态切换（应向玩家移动），但Agent仍无法移动。
• 两种卡顿场景下，NavMesh Agent均处于激活状态且目标位置正常，手动将Agent拖拽到玩家攻击点后，可恢复正常攻击与移动。
