dash in 2d platformer

so i made a dash script . it work but the player can only dash to the left . i want to dash to the right .pls help


here is the script


using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class dash : MonoBehaviour
{
private Rigidbody2D rb;
public float dashspeed;
private float dashTime;
public float startDashTime;
private int direction;

void Start()
{
rb = GetComponent<Rigidbody2D>();
dashTime = startDashTime;
}

void Update()
{
if (direction == 0)
{
if (Input.GetKeyDown(KeyCode.LeftShift))
{
direction = 1;
}
else if (Input.GetKeyDown(KeyCode.RightShift))
{
direction = 2;
}
}
else
{
if (dashTime < -0)
{
direction = 0;
dashTime = startDashTime;
rb.velocity = Vector2.zero;
}
else
{
dashTime -= Time.deltaTime;

if (direction == 1)
{
rb.velocity = Vector2.left * dashspeed;
}
else if (direction == 2)
{
rb.velocity = Vector2.right * dashspeed;

}
}
}
}
}

 

Remove the if(direction == 0) at the beginning of your update and add if(direction != 0) at the start of you if statements for direction == 1 and direction == 2

Code (CSharp):

1. public class dash : MonoBehaviour
2. {
3.     private Rigidbody2D rb;
4.     public float dashspeed;
5.     private float dashTime;
6.     public float startDashTime;
7.     private int direction;
8.  
9.     void Start()
10.     {
11.         rb = GetComponent<Rigidbody2D>();
12.         dashTime = startDashTime;
13.     }
14.  
15.     void Update()
16.     {
17.         if (Input.GetKeyDown(KeyCode.LeftShift)) {
18.             direction = 1;
19.         } else if (Input.GetKeyDown(KeyCode.RightShift)){
20.             direction = 2;
21.         } else {
22.             if (dashTime < -0) {
23.                 direction = 0;
24.                 dashTime = startDashTime;
25.                 rb.velocity = Vector2.zero;
26.             } else {
27.                 dashTime -= Time.deltaTime;
28.                 if(direction != 0){
29.                     if (direction == 1) {
30.                         rb.velocity = Vector2.left * dashspeed;
31.                     }
32.                     if (direction == 2) {
33.                         rb.velocity = Vector2.right * dashspeed;
34.                     }
35.                 }
36.             }
37.         }
38.     }
39. }
