Control different speeds for moving left/right, and facing that direction

Question

I have a game idea... and I need a script where I can control the speed for moving left, and control another speed for moving right. But, I also need to let my player face that direction.

using UnityEngine;

public class NewBehaviourScript : MonoBehaviour
{
    void Update()
    {
        if (Input.GetKey(KeyCode.LeftArrow))
        {
            Vector3 position = this.transform.position;
            position.x -= .5f;
            this.transform.position = position;
        }
        
        if (Input.GetKey(KeyCode.RightArrow))
        {
            Vector3 position = this.transform.position;
            position.x += 1f;
            this.transform.position = position;
        }
        
        if (Input.GetKey(KeyCode.A))
        {
            Vector3 position = this.transform.position;
            position.x -= .5f;
            this.transform.position = position;
        }

           
        if (Input.GetKey(KeyCode.D))
        {
            Vector3 position = this.transform.position;
            position.x += 1f;
            this.transform.position = position;
        }
    }
}

That is my code. I need make it better I guess... and to make the player face that direction.

Answer 1

If I understand the idea you want to achieve correctly, I would suggest that you :

• Store Vector1 : a vector of movement speed values in different directions as you would like
• Store Vector2 : another vector (Horizontal and Vertical Axis) for player inputs (more on that here).
• Scale Vector1 by Vector2 which is component-wise multiplication store that in Vector3 (more on that here).

Now you have read the input from user and have V3 a vector representing the final velocity.

Add that to your player position by any update method.

You can also make it rotate and face the same vector(similar to this reference).
