Write the predefined coding like the following,
 
(Jump,Horizontal,Vertical)
  1. using System.Collections;  
  2. using System.Collections.Generic;  
  3. using UnityEngine;  
  4.   
  5. public class Movement : MonoBehaviour  
  6. {  
  7.     Vector3 Vec;  
  8.     // Start is called before the first frame update  
  9.     void Start()  
  10.     {  
  11.           
  12.     }  
  13.   
  14.     // Update is called once per frame  
  15.     void Update()  
  16.     {  
  17.   
  18.         Vec = transform.localPosition;  
  19.         Vec.y += Input.GetAxis("Jump") * Time.deltaTime * 20;  
  20.         Vec.x += Input.GetAxis("Horizontal") * Time.deltaTime * 20;  
  21.         Vec.z += Input.GetAxis("Vertical") * Time.deltaTime * 20;  
  22.         transform.localPosition = Vec;  
  23.     }  
  24. }  
Save the program.
