Adding Wander option to AI
Hello everyone, i'd like to add a wander function for my AI.
I instantiate a transform where they move to then it gets deleted and a new one is created, it repeats this as long as it is within viewable range but out of the player's range.
It works but the problem is that before they move towards the new location they do a couple spins, probably because of the Rotate line in Move()
Relevant parts of the script:
public class VirusAI : MonoBehaviour {
void Awake()
{
target = player.transform;
myTransform = transform;
int x = Random.Range(-50, 50);
int z = Random.Range(-50, 50);
savedLoc = Instantiate(StartLoc, transform.position + new Vector3(x, 0.0f, z), transform.rotation);
}
#region Movement & Anim
void Update()
{
distance = Vector3.Distance(myTransform.position, target.position); // Check & store distance
if(distance > range * 4) return; //Stop if not viewable -> performance
if(distance < range * 2 && distance > range) // Out of range but viewable -> Wander
{
if (Vector3.Distance(transform.position, savedLoc.transform.position) < stop)
{
StartCoroutine(NewTarget()); //Create new random position
} else {
Move(savedLoc.transform); //Wander to next position
}
}
if (distance <= range)
{
Move(target); //Move to target(Player)
}
}
void Move(Transform target)
{
//Rotate to player
myTransform.rotation = Quaternion.Slerp(myTransform.rotation, Quaternion.LookRotation(target.position - myTransform.position), rotationSpeed * Time.deltaTime);
//Move Forward
if (distance > stop) //Don't get too close
{
myTransform.position += myTransform.forward * moveSpeed * Time.deltaTime;
}
}
IEnumerator NewTarget()
{
yield return new WaitForSeconds(0.5f);
int x = Random.Range(-50, 50);
int z = Random.Range(-50, 50);
Destroy(savedLoc); //Remove old and create new location to "wander" to
savedLoc = Instantiate(StartLoc, transform.position + new Vector3(x, 0.0f, z), transform.rotation);
}
#endregion
}
try putting your rotation line inside " if (distance > stop)" brackets.
I have no idea why this worked but i wanted to prevent NPC's moving in wrong directions and did so by checking the difference in distance between the old and new locations and for some reason the spinning is also gone, i don't understand it and i know it wasn't the wander bool because i tried that already but either way it works now, i'm happy ;)
IEnumerator NewTarget()
{
wander = false;
yield return new WaitForSeconds(0.5f);
while (!wander)
{
int x = Random.Range(-50, 50);
int z = Random.Range(-50, 50);
prevLoc = savedLoc;
savedLoc = Instantiate(Location, transform.position + new Vector3(x, 0.0f, z), transform.rotation);
if (Vector3.Distance(savedLoc.transform.position, target.position) < Vector3.Distance(prevLoc.transform.position, target.position))
{
Destroy(prevLoc); //Remove old savedLoc since there's a new one that's closer
wander = true;
}
}
