Unity 2D Jump Code not working?

Questions & Answers
1

Hello! I watched a tutorial, and here is my jump code. It is not giving me any errors, but it is not doing anything.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class BetterJump1 : MonoBehaviour {

	public float fallMultiplier = 2.5f;
	public float lowJumpMultiplier = 2f;

	Rigidbody2D rb;

	void Awake(){
		rb = GetComponent<Rigidbody2D> ();
	}

	void Update(){
		if (rb.velocity.y < 0) {
			rb.velocity += Vector2.up * Physics2D.gravity.y * (fallMultiplier - 1) * Time.deltaTime;
		} else if (rb.velocity.y > 0 && !Input.GetKeyDown(KeyCode.Space)) {
			rb.velocity += Vector2.up * Physics2D.gravity.y * (lowJumpMultiplier - 1) * Time.deltaTime;
		}

	}
}

Any help is appreciated!

hey ;
i saw your code ;
there is no code here for jumping ;
are u sure u did every thing as the tutorial said;

i modified a little so check this :

     void Update(){
         if (rb.velocity.y <= 0 &&  Input.GetKeyDown(KeyCode.Space))) {
             rb.velocity += Vector2.up * Physics2D.gravity.y * (fallMultiplier - 1) * Time.deltaTime;
         } else if (rb.velocity.y > 0 && !Input.GetKeyDown(KeyCode.Space)) {
             rb.velocity += Vector2.up * Physics2D.gravity.y * (lowJumpMultiplier - 1) * Time.deltaTime;
         }
 
     }
 }
