Help with dashes (using ridigbody 2D)

Hi! So i am creating a small game and im trying to get used to rigidbody movement currently i use .velocity to move around (i am aware of addforce and movePosition) But when i'm trying to do a dash it just won't do anything despite me trying to play with the numbers. any help?

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class ImprovedMove : MonoBehaviour
6. {
7.     public float speed;
8.     public Rigidbody2D rb;
9.  
10.     private float movementH;
11.    
12.     ///Dash
13.  
14.     private float lastDTime;
15.    
16.  
17.     void Start()
18.     {
19.      
20.     }
21.  
22.     // Update is called once per frame
23.     void Update()
24.     {
25.         movementH = Input.GetAxis("Horizontal");
26.  
27.         if (Input.GetKeyDown(KeyCode.Space))
28.         {
29.             jump();
30.  
31.  
32.         }
33.  
34.         if (Input.GetKeyDown(KeyCode.D))
35.         {
36.             float timeSinceLastD = Time.time - lastDTime;
37.             lastDTime = Time.time;
38.            
39.             if(timeSinceLastD <= 0.2f)
40.             {
41.                
42.  
43.  
44.  
45.             }
46.         }
47.  
48.  
49.     }
50.  
51.     void FixedUpdate()
52.     {
53.         rb.velocity = new Vector2(movementH * speed, rb.velocity.y);  
54.     }
55.  
56.     void jump()
57.     {
58.         rb.velocity = new Vector2(movementH * speed, rb.velocity.y + 10);
59.     }
60.  
61. }
62.  

 

I forgot to include the part in if(timeSinceLastD <= 0.2f)
but it was just a velocity increased on x

 

Please paste in the entire script. No need to remove parts out of it.

Yeah sorry about that

 

Amm first of all, place a Debug.Log("Test") on line 41 and see if it's ever being called.

If it is, you might have some issues with rb.velocity overriding each other. Now, if that is the case, I have no idea how it was actually working up until this point. To test out this theory, try commenting line 53 and see if dashing works then.
