Issue With Jumping

Questions & Answers
1

I have an issue where when a ball sprite isn’t rolling it will jump as I expect it to; however, when I have the ball rolling, it doesn’t fall properly or reach the height is should be. Here is my script,
using UnityEngine;
using System.Collections;

public class BallController : MonoBehaviour {

	Vector3 pos;
	float posSmooth = 1.0f;
	float rotSmooth = 0.318f;
	public bool rollingEnabled = true;
	public Rigidbody2D rb;
	public GameObject sprite;
	float thrust = 600f;
	Vector2 zero = new Vector2(0f, 0f);
	bool jumping = false;

	// Use this for initialization
	void Start ()
	{
		pos = transform.position;
	}
	
	// Update is called once per frame
	void Update ()
	{
		if(Input.GetKeyDown (KeyCode.Space))
		{
			jumping = true;
		}
	}

	void FixedUpdate ()
	{
		if(jumping)
		{
			jumping = false;
			rb.velocity = zero;
			rb.AddForce (transform.up * thrust);
		}
		if(rollingEnabled)
		{
			pos.x += posSmooth * Time.deltaTime;
			transform.position = pos;
			sprite.transform.Rotate (Vector3.back, 180.0f * Time.deltaTime * rotSmooth, Space.Self);
		}
	}
}

I thought it might be an issue with Update or FixedUpdate interfering with the other, but after setting my code up like I probably should’ve in the first place, nothing change.

I still don’t know why it wasn’t working the way I had it, but I have found a solution, so if anyone else runs into this issue, at least here is a work around. You can, of course, change the direction of the movement by modifying the values of the Vector3, movement.

Vector3 movement = new Vector3(1.0f, 0.0f, 0.0f); //Goes just after MonoBehaviour.

transform.position += movement *Time.deltaTime; //Goes in fixed update.
