Unity3D-敌人巡逻和拉脱
agent = GetComponent<NavMeshAgent>();//获得导航组件
一．巡逻
agent.speed = speed * 0.5f;//巡逻状态下速度为平时移动的一般
//判断当前巡逻距离是否超过初始巡逻范围
if(Vector3.Distance(wayPoint, transform.position) <= agent.stoppingDistance)
{
if(remainLookAtTime > 0)//等待时间大于0后继续巡逻
{
remainLookAtTime -= Time.deltaTime;
}
else
{
GetNewWayPoint();
}
}
else
{
isWalk = true;
agent.destination = wayPoint;
}
void GetNewWayPoint()
{
remainLookAtTime = lookAtTime;//设置停留时间
float randomX = Random.Range(-patrolRange, patrolRange);//获得指定范围X坐标随机数
float randomZ = Random.Range(-patrolRange, patrolRange);//获得指定范围Y坐标随机数
Vector3 randomPoint = new Vector3(guardPos.x + randomX, transform.position.y, guardPos.z + randomZ);
NavMeshHit hit;
wayPoint = NavMesh.SamplePosition(randomPoint, out hit, patrolRange, 1) ? hit.position : transform.position;//如果随机移动的坐标是可经过的则移动，否则停留到当前的坐标
}
private void OnDrawGizmosSelected()//绘制巡逻可视区域
{
Gizmos.color = Color.blue;
Gizmos.DrawWireSphere(transform.position, sightRadius);
}
-
拉脱(意思是敌人追踪的目标丢失)
//当敌人丢失目标后
if(transform.position != guardPos)//判断当前不处于起始位置
{
agent.isStopped = false;
agent.destination = guardPos;
//是否回到起始位置
if(Vector3.SqrMagnitude(guardPos - transform.position) <= agent.stoppingDistance)
{
transform.rotation = Quaternion.Lerp(transform.rotation, guardRotation, 0.01f);
}
}
