Animation direction...help please..

Hi, I'm having trouble doing the running animation.

The problem appears when I want to change direction while the character is running, it seems that being so fast, the character slides on the floor.

I have two videos, in one the speed is low and in another it is high.

Here I leave the code that I am using.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class PlayerController : MonoBehaviour {
6.  
7.  
8.     public float speed = 2f;
9.     private Rigidbody2D rb2d;
10.     public float maxSpeed = 5f;
11.     private Animator anim;
12.     public bool grounded;
13.     public bool pressrun;
14.  
15.  
16.     void Start () {
17.  
18.  
19.         rb2d = GetComponent<Rigidbody2D> ();
20.         anim = GetComponent<Animator> ();
21.        
22.     }
23.    
24.     // Update is called once per frame
25.     void Update () {
26.  
27.  
28.         anim.SetFloat ("Speed", Mathf.Abs(rb2d.velocity.x));
29.         anim.SetBool ("Grounded", grounded);
30.         anim.SetBool ("PressRun", pressrun);
31.  
32.     }
33.  
34.  
35.  
36.  
37.     void FixedUpdate(){
38.    
39.    
40.    
41.         float h = Input.GetAxis ("Horizontal");
42.         rb2d.AddForce (Vector2.right * speed * h);
43.  
44.  
45.  
46.        
47.         float limitedSpeed = Mathf.Clamp (rb2d.velocity.x, -maxSpeed, maxSpeed);
48.         rb2d.velocity = new Vector2 (limitedSpeed, rb2d.velocity.y);
49.  
50.  
51.         if (Input.GetKey ("k")) {
52.  
53.             pressrun = true;
54.             rb2d.velocity = new Vector2 (limitedSpeed * 2, rb2d.velocity.y);
55.  
56.  
57.         } else {
58.  
59.  
60.             pressrun = false;
61.  
62.         }
63.  
64.         if (h > 0.1f) {
65.        
66.             transform.localScale = new Vector3 (1f, 1f, 1f);
67.        
68.         }
69.  
70.  
71.         if (h < -0.1f) {
72.  
73.             transform.localScale = new Vector3 (-1f, 1f, 1f);
74.  
75.         }
76.  
77.     }
78.  
79.  
80.  
81. }
82.  

Thank you very much and I am sorry for my English.

 

You could keep track of the direction they're travelling and if it changes, set the x portion of the velocity to zero before you apply the new force?
