Enemy not moving towards Player

Hey guys, fairly new to unity. I’ve been trying to get an enemy gameObject to move towards my player game object. I’m not sure whether the error with my following code is a logic error or a syntax error so I shall try and give all relevant information.

My enemy game object if called “Enemy” in the inspector.

My player game object is called “Player” in the inspector.

The code is as follows:

using UnityEngine;
using System.Collections;

public class EnemyAI : MonoBehaviour {

	float spawnPoint;
	float max_speed = 5f;
	public LayerMask ground;
	public bool facingRight = true;
	// Use this for initialization
	void Start () {
	
	}
	
	// Update is called once per frame
	void FixedUpdate () {
	
		float player_X = GameObject.Find ("Player").transform.position.x;
		if (transform.position.x < player_X - 5) {
			if(!facingRight){
				Flip();
			}
			rigidbody2D.velocity = new Vector2 (max_speed, rigidbody2D.velocity.y);

		}else if(transform.position.x > player_X + 5){
			if(facingRight){
				Flip();
			}
			rigidbody2D.velocity = new Vector2 (-1 * max_speed, rigidbody2D.velocity.y);
		}

	}

	void Flip(){
		
		facingRight = !facingRight;
		// Sets facingRight to the opposite of what it just was.
		Vector3 EnScale = transform.localScale;
		// Creates a variable containing the x,y and z scale values.
		EnScale.x *= -1;
		// Changes the direction that the character is facing in.
		transform.localScale = EnScale;
		// Sets this changed value to the game characters value.
		
	}

}
The game is fairly simplistic so far, however if anymore information is required please ask.

Your FixedUpdate has something weird going on:

 void FixedUpdate () {
     float player_X = GameObject.Find ("Player").transform.position.x;
     if (transform.position.x < player_X - 5) {
         ...
     }else if(transform.position.x > player_X + 5){
         ...
     }
 }

This code won’t do anything if the transform’s x-position is between player-X + 5 and player_X - 5. Try to move the character and enemy further away from each other, then it should work.

If the code doesn’t work even when the player’s more than 5 units on the x-axis away from the enemy, then there’s something else going on.

First of all, this script has to be attached to the enemy object, but I’m assuming that’s the case. If not, check that. Also ensure that the script’s not been deactivated on the enemy object.

Secondarily, you’re saying that you’re not sure if it’s a syntax or logic error. If it’s a syntax error, then you should be getting error messages in your console. The same thing should be the case if your rigidbody isn’t set up right. If that’s the case, you’ll have to post what errors you’re getting.
