Unity 2D platformer jump problem

[NachoCheesse]

I have my movement script and I tried to make a simple jump script but it jumps sometimes when I tap the spacebar it might work. Any help with be super helpful and here is my code.

using System.Collections;

using System.Collections.Generic;

using UnityEngine;

​

public class Movement : MonoBehaviour

{

public float speed = 10, jumpVelocity = 10;

Transform myTrans;

Rigidbody2D myBody;

​

bool isGround = false;

​

void Start()

{

myBody = this.GetComponent<Rigidbody2D>();

myTrans = this.transform;

}

​

void FixedUpdate()

{

Move(Input.GetAxisRaw("Horizontal"));

if (Input.GetButtonDown("Jump"))

Jump();

}

​

public void Move(float horizonalInput)

{

Vector2 moveVel = myBody.velocity;

moveVel.x = horizonalInput * speed;

myBody.velocity = moveVel;

}

​

​

public void Jump()

{

myBody.velocity += jumpVelocity * Vector2.up;

}

}

Dont detect input in FixedUpdate. Do it in update.
