I WANT TO MAKE MY BALL JUMP :(

ALL I GOT IS THIS :

using UnityEngine;

using System.Collections;

public class MarbleControl : MonoBehaviour {

public float movementSpeed = 6.0f;

void Update () {

    Vector3 movement = (Input.GetAxis("Horizontal") * -Vector3.left * movementSpeed) + (Input.GetAxis("Vertical") * Vector3.forward *movementSpeed);

    rigidbody.AddForce(movement, ForceMode.Force);

}

void OnTriggerEnter  (Collider other  ) {

    if (other.tag == "Pickup")

    {

        MarbleGameManager.SP.FoundGem();

        Destroy(other.gameObject);

    }

    else

    {

        //Other collider.. See other.tag and other.name

    }        

}

}

Just use Rigidbody.AddForce when the space bar is pressed to propel the rigidbody upwards.

Hmm ive been grubbeling over the same mystery
