My ground checker only works... sometimes

Questions & Answers
1

so basically it works fine on flat ground but if it interacts with a sloped tile like a rock it only has a 50/50 chance of letting my player jump, any help would be greatly appreciated.

void Start()
{
    rb = GetComponent<Rigidbody2D>();
    anim = GetComponent<Animator>();
}

// Update is called once per frame
void Update()
{
    Move();
    Jump();
    CheckIfGrounded();
}
void Move()
{
    float moveInput = Input.GetAxisRaw("Horizontal");
    rb.velocity = new Vector2(moveInput * speed, rb.velocity.y);
   
    if (moveInput == 0)
    {
        anim.SetBool("isRunning", false);
    }
    else
    {
        anim.SetBool("isRunning", true);
    }

    if (moveInput < 0)
    {
        transform.eulerAngles = new Vector3(0, 180, 0);
    }
    else if (moveInput > 0)
    {
        transform.eulerAngles = new Vector3(0, 0, 0);
    }
}

void Jump()
{
    if (Input.GetKeyDown(KeyCode.Space) && isGrounded)
    {
        rb.velocity = new Vector2(rb.velocity.x, jumpForce);
        anim.SetTrigger("Jump");
    }
}

void CheckIfGrounded()
{
    Collider2D collider = Physics2D.OverlapCircle(isGroundedChecker.position, checkGroundRadius, groundLayer);
    if (collider != null)
    {
        isGrounded = true;
        anim.SetBool("IsJumping", false);
    }
    else
    {
        isGrounded = false;
        anim.SetBool("IsJumping", true);
    }
}

}

Try adding an collider in the inspector and assinging that, and also moving from Update() to FixedUpdate() could help. and you should not check if the collider != null, instead check if collider.gameObject.tag == “YOUR GROUND TAG HERE”
