I'm trying to understand why walking diagonally goes faster.

I'm new to C# and I'm creating a top down game for studies, but when I walk diagonally my character walks faster than normal, I've already researched it and I can't solve it, can someone help me? there is my script:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class PlayerController : MonoBehaviour
6. {
7.     public float moveSpeed = 5.5f;
8.     public Rigidbody2D rb;
9.     public Animator animator;
10.     Vector2 movement;
11.  
12.  
13.     void Start()
14.     {
15.  
16.     }
17.     void Update()
18.     {
19.         movement.x = Input.GetAxisRaw("Horizontal");
20.         movement.y = Input.GetAxisRaw("Vertical");
21.  
22.         animator.SetFloat("Horizontal", movement.x);
23.         animator.SetFloat("Vertical", movement.y);
24.         animator.SetFloat("Speed", movement.sqrMagnitude);
25.         if (this.movement.magnitude > 1)
26.         {
27.             this.movement = this.movement.normalized;
28.         }
29.  
30.     }
31.  
32.     void FixedUpdate()
33.     {
34.         rb.MovePosition(rb.position + movement * moveSpeed * Time.fixedDeltaTime);
35.     }
36. }
37.  

 

Because when you do
movement * movementSpeed
the resulting vector is longer than movementSpeed.

You can do it like this
movement.normalized * movementSpeed

 

I would do something like this:

Code (CSharp):

1.     void Update()
2.     {
3.         movement.x = Input.GetAxisRaw("Horizontal");
4.         movement.y = Input.GetAxisRaw("Vertical");
5.         movement = Vector3.ClampMagnitude(movement, 1f);
6.         animator.SetFloat("Horizontal", movement.x);
7.         animator.SetFloat("Vertical", movement.y);
8.         animator.SetFloat("Speed", movement.sqrMagnitude);
9.     }

 

Thanks for the answer now I understand what I went wrong, now it's working perfectly

 

Thanks, your took my doubts about vector, and it worked too!
