Kinda Confused

Ok so basically when I start up the game everythings normal but if I move or jump or do anything my charater shrinks to like 1 or -1 I forgot which one. Also the ground boxes are a bit weird but I'm pretty sure thats just from my awful design
Heres my code.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class playermovement : MonoBehaviour {
6.     public float movementSpeed;
7.     public Rigidbody2D rb;
8.  
9.     public Animator anim;
10.  
11.     public float jumpForce = 20f;
12.     public Transform Player;
13.     public LayerMask GroundLayers;
14.  
15.     float mx;
16.  
17.     private void Update() {
18.         mx = Input.GetAxisRaw("Horizontal");
19.  
20.         if (Input.GetButtonDown("Jump") && IsGrounded()) {
21.             Jump();
22.         }
23.  
24.         if (Mathf.Abs(mx) > 0.05f) {
25.             anim.SetBool("isrunning", true);
26.         } else {
27.             anim.SetBool("isrunning", false);
28.         }
29.  
30.         if (mx > 0f) {
31.             transform.localScale = new Vector3(1f, 1f, 1f);
32.         } else if (mx < 0f) {
33.             transform.localScale = new Vector3(-1f, 1f, 1f);
34.         }
35.  
36.         anim.SetBool("IsGrounded", IsGrounded());
37.     }
38.  
39.     private void FixedUpdate() {
40.         Vector2 movement = new Vector2(mx * movementSpeed, rb.velocity.y);
41.  
42.         rb.velocity = movement;
43.     }
44.  
45.     void Jump() {
46.         Vector2 movement = new Vector2(rb.velocity.x, jumpForce);
47.  
48.         rb.velocity = movement;
49.     }
50.     public bool IsGrounded() {
51.         Collider2D GroundCheck = Physics2D.OverlapCircle(Player.position, 2f, GroundLayers);
52.  
53.         if (GroundCheck != null) {
54.             return true;
55.         }
56.  
57.         return false;          
58.     }
59. }
60.  

 

What is confusing ? what is your expected outcome ?
lines 30 - 34 are settings the scale which is why it is shrinking.

 

What @LethalInjection said, and if your goal is to flip a character with a scale of more than 1,1,1, then you need to set the scale to what it actually is, or do it dynamically:

Code (CSharp):

1.     void Update()
2.     {
3.         if (mx > 0f)
4.         {
5.             transform.localScale = new Vector3(Mathf.Abs(transform.localScale.x), transform.localScale.y, transform.localScale.z);
6.         }
7.         else if (mx < 0f)
8.         {
9.             transform.localScale = new Vector3(-Mathf.Abs(transform.localScale.x), transform.localScale.y, transform.localScale.z);
10.         }
11.     }

 

Thank ya'll so much
