❔ How to make it NOT random and follow a Transform[]
Hello, new here and hope to get some help/pointers on what to do here.
I have made a script where my NPC can walk to different positions and wait for a sec, before moving on. But it walks to RANDOM positions... I can't find ANY tutorial on how to make an NPC go to each spot in order. And wait...
This is my Script:
[CODE]
public class patrolScript : MonoBehaviour
{
public float speed;
private float waitTime;
public float startWaitTime;
public Transform[] moveSpots;
private int randomSpot;
// Start is called before the first frame update
void Start()
{
waitTime = startWaitTime;
randomSpot = Random.Range(0, moveSpots.Length);
}
// Update is called once per frame
void Update()
{
transform.position = Vector2.MoveTowards(transform.position, moveSpots[randomSpot].position, speed * Time.deltaTime);
if(Vector2.Distance(transform.position, moveSpots[randomSpot].position) < 0.2f)
{
if(waitTime <= 0)
{
randomSpot = Random.Range(0, moveSpots.Length);
waitTime = startWaitTime;
}
else
{
waitTime -= Time.deltaTime;
}
}
}
}
[/CODE]

well instead of going to a random spot, make it go to the next spot
Yes, HAha, thats what I want, But I really dont know how :S
Im in the Beginner forum. right? 😛
keep track of which spot its at, and increment it once the wait time is complete
I deleted all Random events and put [1] instead of random. That way he walked to spot 1. But then he stops there cuz he dont know where to go next
what kind of "function should I google for that?" Is it a Transform [] thing or what am I looking for?
realistically your not going to google to find something to spoonfeed you this. You're going to have to figure out how to make the logic for it, theres not much your going to have to change to get this to work as expected
I found something like this. destPoint = (destPoint + 1) % points.Length; Seem to be what Im looking for
Just... save the index of the current point
Then you can go to that point + 1
Aigh, Index is the "[ ]" symbols?
It's a number
[] is the indexer
array[index]
That's how you get an item from an array
Instead of using a random value, use some index
Then increment that index
So next time you access the array, you'll take the next itemAh, I think that make sense, thank you! At least I know what to read up about to get it to work!
