Infinite Jump problem

Unity Engine
1

Hello! I just coded in my jump and movement for my character and it works great, but for some reason I can jump infinitely. What can I change or add to my code to fix this? Thank you for the help in advance!

Here is my code:
{
public float movementSpeed;
public Rigidbody2D rb;
public float jumpForce = 20f;
public Transform feet;
public LayerMask groundLayers;
float mx;
private void Update()
{
mx = Input.GetAxis(“Horizontal”);
if (Input.GetButtonDown(“Jump”) && isGrounded())
{
Jump();
}
}
private void FixedUpdate()
{
Vector2 movement = new Vector2(mx * movementSpeed, rb.velocity.y);
rb.velocity = movement;
}
void Jump()
{
Vector2 movement = new Vector2(rb.velocity.x, jumpForce);
rb.velocity = movement;
}
public bool isGrounded()
{
Collider2D groundCheck = Physics2D.OverlapCircle(feet.position, 0.5f, groundLayers);
if (groundCheck != null)
{
return true;
}
return false;
}
}

Whad do you mean infinitely?Can you use “insert code”?

I can continue to press space, I only want to jump once and not jump in the air an infinite number of times.

{
public float movementSpeed;
public Rigidbody2D rb;
public float jumpForce = 20f;
public Transform feet;
public LayerMask groundLayers;

float mx;

private void Update()
{
mx = Input.GetAxis(“Horizontal”);
if (Input.GetButtonDown(“Jump”) && isGrounded())
{
Jump();
}
}

private void FixedUpdate()
{
Vector2 movement = new Vector2(mx * movementSpeed, rb.velocity.y);

rb.velocity = movement;

}

void Jump()
{
Vector2 movement = new Vector2(rb.velocity.x, jumpForce);
rb.velocity = movement;
}

public bool isGrounded()
{
Collider2D groundCheck = Physics2D.OverlapCircle(feet.position, 0f, groundLayers);

if (groundCheck != null)
{
return true;
}
return false;
}
}
