Make movement of an object independant.

Hello!

I am making a top down 2d game. My character has currently a movement script and a rotation script (i like to keep things separated). The movment script is simple; press W to go up, A to go left, S to go down and D to go right. The rotation script makes the character always face the mouse cursor.

The problem is that when in gamemode the character moves right if he is facing right when i press W, he moves left if he is facing left when i press W.

He moves where he is facing when i want him to go up. This applies for every direction. He needs to look at the direction he is going for the controls to make sence. How could i “seperate” the movement from the rotation?

This is the movement script by the way:

using UnityEngine;
using System.Collections;

public class PlayerMovement : MonoBehaviour {

	public float speed;	

	void Update () {
		Movement ();
	}	

	void Movement()
	{
		if (Input.GetKey (KeyCode.D)) {
			transform.Translate (Vector2.right * speed * Time.deltaTime);
		}
		if (Input.GetKey (KeyCode.W)) {
			transform.Translate (Vector2.up * speed * Time.deltaTime);
		}
		if (Input.GetKey (KeyCode.A)) {
			transform.Translate (-Vector2.right * speed * Time.deltaTime);
		}
		if (Input.GetKey (KeyCode.S)) {
			transform.Translate (-Vector2.up * speed * Time.deltaTime);
		}
		if ((Input.GetKey (KeyCode.A) && Input.GetKey (KeyCode.W))
		    ||(Input.GetKey (KeyCode.W) && Input.GetKey (KeyCode.D))
		    ||(Input.GetKey (KeyCode.D) && Input.GetKey (KeyCode.S))
		    ||(Input.GetKey (KeyCode.S) && Input.GetKey (KeyCode.A))) 
		{	
			speed = 0.85f;
		} else {
			speed = 1.2f;
		}
	}
						
}

This is the rotation script:

using UnityEngine;
using System.Collections;

public class LookAtMouse : MonoBehaviour {

	void Update () {
		//rotation
		Vector3 mousePos = Input.mousePosition;
		mousePos.z = 5.23f;
		
		Vector3 objectPos = Camera.main.WorldToScreenPoint (transform.position);
		mousePos.x = mousePos.x - objectPos.x;
		mousePos.y = mousePos.y - objectPos.y;
		
		float angle = Mathf.Atan2(mousePos.y, mousePos.x) * Mathf.Rad2Deg;
		transform.rotation = Quaternion.Euler(new Vector3(0, 0, angle-90));
	}
}

Thank you in advance!

Nvm i think i found a solution. I just made a new gameobject named “charlegs” (lol) and attached the movementscript to it, i then made the charcter a child of the charlegs :slight_smile:
