How can i normalize 2d Vectors?
I´ve coded some very basic player movement
using UnityEngine;
using System.Collections;
public class PlayerController : MonoBehaviour {
private bool isDodging;
private Vector2 direction;
private float stamina;
private float characterSpeed = 0.10F;
void Start()
{
stamina = 100f;
}
void FixedUpdate()
{
if (Input.GetKey(KeyCode.W))
{
direction = Vector2.up;
transform.Translate(direction * characterSpeed);
}
if (Input.GetKey(KeyCode.A))
{
direction = Vector2.left;
transform.Translate(direction * characterSpeed);
}
if (Input.GetKey(KeyCode.S))
{
direction = Vector2.down;
transform.Translate(direction * characterSpeed);
}
if (Input.GetKey(KeyCode.D))
{
direction = Vector2.right;
transform.Translate(direction * characterSpeed);
}
if (isDodging != true)
{
if (Input.GetKey(KeyCode.LeftShift))
{
characterSpeed = 0.2F;
}
else
{
characterSpeed = 0.10F;
}
}
if (Input.GetKeyDown(KeyCode.Space))
{
StartCoroutine("Roll");
}
}
IEnumerator Roll()
{
isDodging = true;
characterSpeed = 0.20f;
yield return new WaitForSeconds(0.3f);
characterSpeed = 0.05f;
yield return new WaitForSeconds(0.25f);
isDodging = false;
characterSpeed = 0.10f;
}
}
When 2 directions are pressed simultaneously the resulting speed is higher.
How can i prevent this?
void FixedUpdate()
{
direction = new Vector2(Input.GetAxis("Horizontal"),Input.GetAxis("Vertical"));
direction.Normalize();
transform.Translate(direction*Time.deltaTime*characterSpeed);
}
Unity has a built-in function for Vector2 to normalize the Vectors.
if(direction.sqrMagnitude > 1) // Only normalize if necessary
{
direction = direction.normalized;
}
