Question My character multijumps

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class hareketbenim : MonoBehaviour
6. {
7.  
8.     public float speed = 8f;
9.     public float jump = 16f;
10.     private float horizontal;
11.     public bool isJumping;
12.     private bool panelclicked = false;  // i have a panel to start the game so it is controlling the controls depending on the panel is clicked
13.     public Rigidbody2D rb;
14.  
15.     void Update()
16.     {
17.         if (panelclicked == true)
18.         {
19.             horizontal = -Input.GetAxis("Horizontal");
20.             rb.velocity = new Vector2(speed * horizontal, rb.velocity.y);
21.             if (Input.GetKeyDown(KeyCode.W) && isJumping == false)
22.             {
23.                 rb.AddForce(new Vector2(rb.velocity.x, jump));
24.             }
25.         }
26.     }
27.  
28.     private void OnCollisionEnter2D(Collision2D other)
29.     {
30.             if (other.gameObject.CompareTag("ground"))
31.             {
32.                 isJumping = false;
33.             }
34.  
35.             if (other.gameObject.CompareTag("flag"))
36.             {
37.                 Destroy(other.gameObject);
38.             }
39.     }
40.  
41.     void OnCollisionExit2D(Collision2D other)
42.     {
43.             if (other.gameObject.CompareTag("ground"))
44.             {
45.                 isJumping = true;
46.             }
47.     }
48.  
49.     public void ControllerOpener()
50.     {
51.         panelclicked = true;
52.     }
53.  
54. }

I implemented this code into my character but it seems my character is multijumping. I tried some solutions, including make isJumping true in the part where it makes jump, but this time it can jump only once, then not jump even he is on the ground.


This problem started after I brought a panel into my game that will activate the controls(so the player will not move until the button is clicked).

So is there any way to solve this problem?

 

So, you managed to stop the multijumps, but you don't want only one jump?
I'm assuming you want a double jump or something.
Have a counter for how many jumps the player makes, and flip the isJumping to true when hitting the max amount.

 

oh, sorry, when I said jumping once it only jumps ONCE, and then not when ı clicked into w.
