NPC sinking through ground while trying to follow player

Hello! So I have a level in my game where an enemy is trying to chase after the player. I know this question has been asked a hundred times, but I haven't been able to use the information in those answers. What my issue is is, is that when my enemy chases after my character, he started to sink through the floor as he walks while tilting upwards, until he disappears. I am currently using a box collider on him, although I've used a rigidbody and charactercontroller up to this point, which didn't work. Here is my movement code below-

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityStandardAssets.Characters.FirstPerson;
5. public class MovingScript : MonoBehaviour {
6.     private Animator anim;
7.     public GameObject player;
8.     public float dist;
9.     //active runs the corrutine
10.     public bool active;
11.     //deactive keeps the corrutine from rerunning
12.     public bool deactive;
13.     public float movespeed = 10f;
14.     public Transform player2;
15.     // Use this for initialization
16.     void Start() {
17.         active = true;
18.         anim = GetComponent<Animator>();
19.         player = GameObject.Find("FPSController");
20.         deactive = false;
21.         if (active == true)
22.         {
23.             StartCoroutine(Run());
24.         }
25.     }
26.  
27.     // Update is called once per frame
28.     void Update() {
29.         float dist = Vector3.Distance(player.transform.position, transform.position);
30.          print("The player is:" + dist);
31.      
32.        
33.         if (deactive == false)
34.         {
35.             anim.Play("CombatIdle");
36.         }
37.         if (deactive == true && dist >= 3)
38.         {
39.              transform.LookAt(player2.position);
40.             transform.Translate(-transform.forward * movespeed * Time.deltaTime);
41.        
42.             anim.Play("Walk");
43.          
44.         }
45.         else if (deactive == true && dist <= 3)
46.         {
47.             anim.Play("CombatIdle");
48.         }
49.  
50.     }
51.     IEnumerator Run()
52.     {
53.         //five seconds of dialogue
54.         yield return new WaitForSeconds(5);
55.         deactive = true;
56.         active = false;
57.     }
58.  
59.        
60. }
61.  
62.  

Any help would be appreciated!

 

Code (CSharp):

1. transform.Translate(-transform.forward * movespeed * Time.deltaTime);

This ignores physics and just goes to that position, use a character Controller or a rigidbody if you want them to not go through objects.

example:

Code (CSharp):

1. transform.GetComponent<CharacterController>().Move(-transform.forward * movespeed * Time.deltaTime);

 

Thank you! That worked very well. My only issue is that the character collider causes the enemy to float upwards a few inches while it walks towards the player. Any advice on that? And again, thanks for your previous answer- I really appreciate it.

 

I haven't tested this code but something like this would work

Code (CSharp):

1.         direction = -transform.forward;
2.         if (controller.isGrounded)
3.         {
4.             gravity = -0.1f;
5.         }
6.  
7.         gravity -= gravityStrength * Time.deltaTime;
8.         controller.Move(new Vector3(direction.x, gravity, direction.y) * speed * Time.deltaTime);

basically create ur own gravity
