Enemy Movement

Hi there!

Im working on a game at the moment that uses a grid for movement. The trouble am having at the moment is with moving my enemies. I have it at the moment so that the enemies will move in the grid and will move in a random direction once it reaches a new grid. I am however after a way to make it so that it stays in the direction it picks, and keeps going for a random period of time (e.g. 2 - 4 seconds) and then it chooses another direction to go, but also if it it hits any objects then it will pick a new direction.

Here is the script that I am currently using. Any help would be greatly appreciated.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class EnemyGridMove : MonoBehaviour
{

    public float moveSpeed = 1f;
    public Transform EnemyMovePoint;
    public float RandomMoveX;
    public float RandomMoveZ;


    // Start is called before the first frame update
    void Start()
    {

        EnemyMovePoint.parent = null;
    }

    void Update()
    {
        transform.position = Vector3.MoveTowards(transform.position, EnemyMovePoint.position, moveSpeed * Time.deltaTime);
        RaycastHit hit;
        int RandomMoveX = Random.Range(-1, 2);
        int RandomMoveZ = Random.Range(-1, 2);


        if (Vector3.Distance(transform.position, EnemyMovePoint.position) <= 0.05f)
        {
            if (!Physics.SphereCast(transform.position, 0.5f, new Vector3(RandomMoveX, 0, RandomMoveZ), out hit, 1f))
            {
                EnemyMovePoint.position += new Vector3(RandomMoveX, 0f, RandomMoveZ);
            }
        }
    }
}

Thanks!

1, make use of variables, though in your situation ints would be more appropriate than floats for the sake of using the int version of Random.Range.
2, as long as you know your condition triggers, in this case your “if/else” statements, you should be able to do what you want when said conditions are triggered.
