在Unity2D中实现敌人自动巡逻有多种方法,以下是其中一种简单的方法:
1. 创建一个空物体并将其命名为“PatrolPoints”,在该物体下创建多个子物体,每个子物体代表一个巡逻点。
2. 在敌人的脚本中添加一个变量来存储巡逻点的数组,并在Start()函数中初始化该数组:
```csharp
public Transform[] patrolPoints;
void Start()
{
patrolPoints = GameObject.Find("PatrolPoints").GetComponentsInChildren<Transform>();
}
```
3. 在Update()函数中,让敌人沿着巡逻点移动:
```csharp
void Update()
{
transform.position = Vector2.MoveTowards(transform.position, patrolPoints[currentPoint].position, speed * Time.deltaTime);
if (Vector2.Distance(transform.position, patrolPoints[currentPoint].position) < 0.1f)
{
currentPoint++;
if (currentPoint >= patrolPoints.Length)
{
currentPoint = 0;
}
}
}
```
在每一帧中,使用Vector2.MoveTowards()函数来移动敌人,将其位置逐渐移动向当前的巡逻点。一旦敌人到达巡逻点,就将其当前点的索引加1,并检查是否已经到达所有巡逻点,如果是,则将其当前点的索引重置为0。
4. 在场景中放置巡逻点,调整敌人的移动速度和巡逻点的顺序,即可实现敌人的自动巡逻。
