Just trying to jump

hey, I’m just starting out and barely know anything about unity or coding in but I’m trying to make a game. can you tell me what wrong with this code besides everything.

using UnityEngine;

public class jump : MonoBehaviour
{

private void FixedUpdate(Collision collisionInfo)
{
if (Input.GetKeyDown(KeyCode.Space))
{

if (collisionInfo.collider.tag == “ground”)
{
Debug.Log(“JUMP”);

}

}
}
}

If you had saved this script, you would have seen in the console that FixedUpdate doesn’t take parameters when you went back into unity. Also, read the part at the top of this forum that explains code tags so your code doesn’t look like that.
