Hey Working on something new here. I have an enemy for a game I'm coding. I'm trying to modularize by stuff more so I have an overall AIMovement.cs file that handles well... movement. I also have AIUtility.cs which handles any randomization of the movement such that the parent makes simple calls and the utility takes care of most things concerning IEnumerators. So AIUtility makes use of System.Random to generate most of its wait times with maxes given by the editor. So at Start() I generate the random seed for waiting. The problem is that when the game starts I run a spawner script that basically spawns a random number of prefabs at the start of the game mostly used for testing at this point though I'm sure it will come in handy later. Its just that all my enemies behave in the exact same way! Now some enemies are originally made to teleport a few times (at random) and then self destruct. Its kind of cool to have it all happen at once and turn the game into a mini bullet hell but for standard enemies it totally sucks! How can I get this to stop? Here are the scripts. I did pull out some code that shouldn't change the problem as these scripts are made for more than one type of mob. Also a few things have not been implemented yet. If I need to restructure I'll cry, but I'll still do it. Any help is appreciated.
Spawner:
using UnityEngine;
public class SpawnerScript : MonoBehaviour
{
[SerializeField] private GameObject gameObj;
private readonly System.Random _random = new System.Random();
private int numOfSpawns;
private Vector3[] spawnLocations;
private void Start() {
numOfSpawns = _random.Next(3, 7);
spawnLocations = new Vector3[numOfSpawns];
for(int i = 0; i < numOfSpawns; i++){
spawnLocations[i] = Camera.main.ScreenToWorldPoint(new Vector3(Random.Range(0,Screen.width), Random.Range(0,Screen.height), 10));
}
for(int i = 0; i < numOfSpawns; i++){
GameObject.Instantiate(gameObj,spawnLocations[i],Quaternion.identity);
}
}
}

//Got Stuck here. Setting velocity, then changed face, then set Speed caused
//quite a few bugs that were very quiet.
