Ground check doesnt work for me? Script problem

Unity Engine
1

Hi, im a beginner in gam dev. Is there something wrong with my code?
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class movement : MonoBehaviour
{
Animator animator;
Rigidbody2D rb2d;
SpriteRenderer spriterenderer;
bool isgrounded;
[SerializeField]
Transform groundcheck;
// Start is called before the first frame update
void Start()
{
animator = GetComponent();
rb2d = GetComponent();
spriterenderer = GetComponent();
}
// Update is called once per frame
private void FixedUpdate()
{
if (Physics2D.Linecast(transform.position,groundcheck.position, 1 << LayerMask.NameToLayer(“ground”)))
{
isgrounded = true;
}
else
{
isgrounded = false;
}
if (Input.GetKey(“d”) || Input.GetKey (“right”))
{
rb2d.velocity = new Vector2(7, rb2d.velocity.y);
if (isgrounded)

animator.Play(“char_run”);

spriterenderer.flipX = false;
}
else if (Input.GetKey(“a”)|| Input.GetKey(“left”))
{
rb2d.velocity = new Vector2(-7, rb2d.velocity.y);
if (isgrounded)

animator.Play(“char_run”);
spriterenderer.flipX = true;
}
else
{
if (isgrounded)
animator.Play(“char_idle”);
rb2d.velocity = new Vector2(0, rb2d.velocity.y);
}
if (Input.GetKey(“space”) && isgrounded)
{

rb2d.velocity = new Vector2(rb2d.velocity.x, 3);
animator.Play(“char_jump”);
}

}
}

Here is the problem, everytime i remove all the “if(isgrounded)” from the inputs, my character can walk left and right perfectly fine but jumping is another issue. It keeps replaying the animation for jumping when i hit spacebar or hold onto spacebar.

but with this code above i mentioned, is the one that stops me from moving my character. whenever i hit left or right. it wont move at all but only plays the animation left and right and the jump button wont even work for me.

First, use code tags when posting code.

Second, make “isgrounded” public and watch its value in the inspector while playing. Does it always have the value you expect it to have? (e.g. checked while you’re on the ground)
