I have been trying to write a script for an enemy were while the player is within a certain space it will teleport to a random position within a set area and fire a projectile. I want this to repeat every few seconds. However when I run the script in game it will wait a the set time execute and then the enemy will just teleport to a random position every frame rather than once every few seconds.
here is my script. any help would be much appreciated.
void Update()
{
if (player.transform.position.x >= -45f && player.transform.position.x <= -27f &&
player.transform.position.y >= 5f && player.transform.position.y <= 14f)
{
StartCoroutine(attack());
}
}
IEnumerator attack()
{
yield return new WaitForSeconds(movementTimer);
transform.position = new Vector3(Random.Range(-44f, -28f), Random.Range(9.5f, 13.22f));
}

Assuming you want to do this with a coroutine, you can try the following:
bool shouldTeleport = false;
void Start()
{
StartCoroutine(attack());
}
void Update()
{
if (player.transform.position.x >= -45f && player.transform.position.x <= -27f &&
player.transform.position.y >= 5f && player.transform.position.y <= 14f)
{
shouldTeleport = true;
} else {
shouldTeleport = false;
}
}
IEnumerator attack()
{
while(true){
if (shouldTeleport){
transform.position = new Vector3(Random.Range(-44f, -28f), Random.Range(9.5f, 13.22f));
}
yield return new WaitForSeconds(movementTimer);
}
}
This should work, however I would do this using a simpler idea, which uses a countdown timer inside the Update loop:
float movementTimer = 1f;
float countdown = 0f;
void Update()
{
if (player.transform.position.x >= -45f && player.transform.position.x <= -27f &&
player.transform.position.y >= 5f && player.transform.position.y <= 14f)
{
countdown -= Time.deltaTime;
if (countdown <= 0){
transform.position = new Vector3(Random.Range(-44f, -28f), Random.Range(9.5f, 13.22f));
countdown = movementTimer;
}
}
}
I didn’t actually test this code but you should be getting the idea.
