Physics orientation bug

Unity Engine
1

So I’m trying to create a script where the enemy locates the player and automatically move towards them, but I have run into a bit of an error as when I click play, the enemy is orientated wrong.

My code:

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

public class EnemyMovement : MonoBehaviour {
   
    public Transform player;

    private Rigidbody2D rb;
    private Vector2 movement;

    public float moveSpeed;

    void Start() {
        rb = this.GetComponent<Rigidbody2D>(); //Gets ridibody2d component of enemy and assigns it to rb
    }
   
    void Update() {
        Vector3 direction = player.position - transform.position; //Finds direction of enemy relative to player
        float angle = Mathf.Atan2(direction.y, direction.x) * Mathf.Rad2Deg; //Finds angle of enemy relative to player in degrees
        rb.rotation = angle;

        direction.Normalize();
        movement = direction;
    }

    private void FixedUpdate() {
        moveCharacter(movement);
    }
    void moveCharacter(Vector2 direction) {
        rb.MovePosition((Vector2)transform.position + (direction * moveSpeed * Time.deltaTime));
    }
}

My enemy inspector:
My player inspector:

If anyone can find the problem, it would be a great help, thanks!

A few basics:

  1. Imported models aren’t at the orientation you’d expect for a variety of reasons, but thats solved by making the imported model a child so you an offset it in position and rotation as you’d like. Can do it in math too but this is a simple answer to start.

  2. Perhaps just add a rotation in code? I mean, there doesn’t seem to a bug here, just lack of extra support code to get the desired behaviour.

It’s probably just the disconnect between 3d package rotation and where the math defaults to.

How could i add that rotation then?

EDIT: I’ve done it:

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

public class EnemyMovement : MonoBehaviour {
   
    public Transform player;

    private Rigidbody2D rb;
    private Vector2 movement;

    public float moveSpeed;

    void Start() {
        rb = this.GetComponent<Rigidbody2D>();
    }
   
    void Update() {
        Vector3 direction = player.position - transform.position;
        float angle = Mathf.Atan2(direction.y, direction.x) * Mathf.Rad2Deg;
        rb.rotation = angle;

        transform.LookAt(player.position);
        transform.Rotate(new Vector3(0,90,0),Space.Self);

        direction.Normalize();
        movement = direction;
    }

    private void FixedUpdate() {
        moveCharacter(movement);
    }
    void moveCharacter(Vector2 direction) {
        rb.MovePosition((Vector2)transform.position + (direction * moveSpeed * Time.deltaTime));
    }
}

Yep plenty of ways to handle it, and that’s one of many. Nice one. You just need to be expecting this sort of thing really, it’s not unusual :slight_smile:
