Question Dashing Mechanic

Hello! I've been following a tutorial on youtube on how to script a dashing mechanic into my 2D platformer. I followed along with the guide and the youtuber made it so that you have to double tap to dash. I don't want that. I want to make it so that you can tap the dash button once but don't know how to do it. Please help!

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class DoubleJump : MonoBehaviour
6. {
7.    public float speed = 10f;
8.    public float jumpPower = 20f;
9.    public int extraJumps = 1;
10.    [SerializeField] LayerMask groundLayer;
11.    [SerializeField] Rigidbody2D rb;
12.    [SerializeField] Transform feet;
13.  
14.    int jumpCount = 0;
15.    bool isGrounded;
16.    float mx;
17.    float jumpCoolDown;
18.  
19.    public float dashDistance = 15f;
20.    bool isDashing;
21.    float tapTime;
22.    KeyCode lastKeyCode;
23.  
24.    private void Update()
25.    {
26.        mx = Input.GetAxisRaw("Horizontal");
27.  
28.        if (Input.GetButtonDown("Jump"))
29.        {
30.            Jump();
31.        }
32.  
33. // Dashing
34.        if (Input.GetKeyDown(KeyCode.X))
35.        {
36.            if (tapTime > Time.time && lastKeyCode == KeyCode.X)
37.            {
38.                StartCoroutine(Dash(1f));
39.            }
40.            else
41.            {
42.                tapTime = Time.time + 0.3f;
43.            }
44.  
45.            lastKeyCode = KeyCode.X;
46.        }
47.  
48.        CheckGrounded();
49.    }
50.  
51.    private void FixedUpdate()
52.    {
53.        if (!isDashing)
54.        rb.velocity = new Vector2(mx * speed, rb.velocity.y);
55.    }
56.  
57.    void Jump()
58.    {
59.        if (isGrounded || jumpCount < extraJumps)
60.        rb.velocity = new Vector2(rb.velocity.x, jumpPower);
61.        jumpCount++;
62.    }
63.  
64.    void CheckGrounded()
65.    {
66.        if (Physics2D.OverlapCircle(feet.position, 0.5f, groundLayer))
67.        {
68.            isGrounded = true;
69.            jumpCount = 0;
70.            jumpCoolDown = Time.time + 0.2f;
71.        }
72.        else if (Time.time < jumpCoolDown)
73.        {
74.            isGrounded = true;
75.        }
76.        else
77.        {
78.            isGrounded = false;
79.        }
80.    }
81.  
82.    IEnumerator Dash (float direction)
83.    {
84.        isDashing = true;
85.        rb.velocity = new Vector2(rb.velocity.x, 0f);
86.        rb.AddForce(new Vector2(dashDistance * direction, 0f), ForceMode2D.Impulse);
87.        float gravity = rb.gravityScale;
88.        rb.gravityScale = 0;
89.        yield return new WaitForSeconds(0.4f);
90.        isDashing = false;
91.        rb.gravityScale = gravity;
92.    }
93. }

 

Might work if you remove all the extra chuff inside from line 35 to line 46 and instead ONLY do line 38 when you press X. It's worth a try.

 

It worked thanks!
