Question by sarusian · May 27, 2014 at 08:28 PM · rotate objectmove speed

Increasing rotate speed.

I'm trying to make a mock solar system, but I've ran into two issues, first I don't know how to increase the rotate speed of earth, and loop it but also make it orbit another object, like the sun. My only question is how do I increase rotate speed? using UnityEngine; using System.Collections;

 using UnityEngine;
 using System.Collections;
 
 public class Rotate : MonoBehaviour {
 
     // Use this for initialization
     void Start () {
     
     }
     
     // Update is called once per frame
     void Update () {
           // Make Object Rotate to Right
         transform.Rotate(Vector3.up * Time.deltaTime, Space.World);
     }
 }
 

What do I do to make earth move faster.

Multiply Time.deltaTime by another variable to add some scaling.

Tip: Child object transforms are relative to the parent. So a Moon transform's 0,0,0 would be the centre of the orbiting Parent planet.

Rotate example from docs:

 function Update()
 {
     // Slowly rotate the object around its X axis at 1 degree/second.
     transform.Rotate(Time.deltaTime, 0, 0);
 
     // ... at the same time as spinning it relative to the global
     // Y axis at the same speed.
     transform.Rotate(0, Time.deltaTime, 0, Space.World);
 }
