Why Cant i Jump

Hello,
So I Tried Programming The Player To Move and Jump (2D) For Now it only worked on moving
when I first started jumping worked but I had a bug where I can just press space and jump forever so I added a Grounded Variable and that's where it all went downhill
Please Help[ me by telling me what's wrong with my code

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class Platformer : MonoBehaviour
6.  
7. {
8. public float speed;
9. public float jumpForce;
10. bool isGrounded = false;
11. public Transform isGroundedChecker;
12. public float checkGroundRadius;
13. public LayerMask groundLayer;
14.  
15.  
16.    Rigidbody2D rb;
17. void Start() {
18.     rb = GetComponent<Rigidbody2D>();
19. }
20.  
21.     // Update is called once per frame
22.    void Update()
23. {
24.     Move();
25.     Jump();
26.     CheckIfGrounded();
27. }
28. void Move() {
29.     float x = Input.GetAxisRaw("Horizontal");
30.     float moveBy = x * speed;
31.     rb.velocity = new Vector2(moveBy, rb.velocity.y);
32.     }
33. void Jump() {
34.     if (Input.GetKeyDown(KeyCode.Space) && isGrounded) {
35.         rb.velocity = new Vector2(rb.velocity.x, jumpForce);
36.     }
37. }
38. void CheckIfGrounded() {
39.     Collider2D collider = Physics2D.OverlapCircle(isGroundedChecker.position, checkGroundRadius, groundLayer);
40.     if (collider != null) {
41.         isGrounded = true;
42.     } else {
43.         isGrounded = false;
44.     }
45. }
46. }
47.  

 

Debug.Log(isGrounded) at the start of your jump to see if your grounded; could be the issue.
Maybe CheckIfGrounded should happen before Jump?

 

i Didnt understand I'm new to C# can you please explain?
Thank You

 

If you debug when hitting space it will tell you if your isGrounded variable is working properly. If the console prints true then your player is grounded so you can eliminate that as an issue.

Code (CSharp):

1. void Jump()
2. {
3.    if (Input.GetKeyDown(KeyCode.Space))
4.    {
5.        Debug.Log(isGrounded); //print to console to see if you are grounded when pressing space
6.        if(isGrounded)
7.         {
8.             rb.velocity = new Vector2(rb.velocity.x, jumpForce);
9.         }
10.     }
11.  }

 

Ok This Is The New Code But After i add it, it gives me this error
"Assets\Platformer.cs(44,39): error CS1026: ) expected"

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. public class Platformer : MonoBehaviour
5. {
6. public float speed;
7. public float jumpForce;
8. bool isGrounded = false;
9. public Transform isGroundedChecker;
10. public float checkGroundRadius;
11. public LayerMask groundLayer;
12.    Rigidbody2D rb;
13. void Start() {
14.     rb = GetComponent<Rigidbody2D>();
15. }
16.     // Update is called once per frame
17.    void Update()
18. {
19.     Move();
20.     CheckIfGrounded();
21.     Jump();
22.  
23. }
24. void Move() {
25.     float x = Input.GetAxisRaw("Horizontal");
26.     float moveBy = x * speed;
27.     rb.velocity = new Vector2(moveBy, rb.velocity.y);
28.     }
29. void CheckIfGrounded() {
30.     Collider2D collider = Physics2D.OverlapCircle(isGroundedChecker.position, checkGroundRadius, groundLayer);
31.     if (collider != null) {
32.         isGrounded = true;
33.     } else {
34.         isGrounded = false;
35.     }
36. }
37. void Jump()
38. {
39.    if (Input.GetKeyDown(KeyCode.Space);
40.    {
41.        Debug.Log(isGrounded); //print to console to see if you are grounded when pressing space
42.        if(isGrounded);
43.         {
44.             rb.velocity = new Vector2(rb.velocity.x, jumpForce);
45.         }
46.     }
47. }
48. }

 

Sorry its
"Assets\Platformer.cs(39,39): error CS1026: ) expected"

 

line 39 should have another closing parenthesizes instead of semicolon.
Line 42 should not have semicolon.
