# How can I rotate an object with random speed with some delays?

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

public class Turn_Move : MonoBehaviour {
public int TurnX;
public int TurnY;
public int TurnZ;

public int MoveX;
public int MoveY;
public int MoveZ;

public bool World;

// Use this for initialization
void Start () {

}

// Update is called once per frame
void Update () {
if (World == true) {
transform.Rotate(TurnX * Time.deltaTime,TurnY * Time.deltaTime,TurnZ * Time.deltaTime, Space.World);
transform.Translate(MoveX * Time.deltaTime, MoveY * Time.deltaTime, MoveZ * Time.deltaTime, Space.World);
}else{
transform.Rotate(TurnX * Time.deltaTime,Random.Range(3,300) * Time.deltaTime,TurnZ * Time.deltaTime, Space.Self);
transform.Translate(MoveX * Time.deltaTime, MoveY * Time.deltaTime, MoveZ * Time.deltaTime, Space.Self);
}
}
}


This is the random part :

Random.Range(3,300)


but sine it's changing the random numbers too quick the changes are almost not visible. I want somehow to make that if for example the next random will stay for example 5 seconds at this speed number then move to the next random number and again stay at this number 5 seconds and so on.

Tried this :

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

public class Turn_Move : MonoBehaviour {
public int TurnX;
public int TurnY;
public int TurnZ;

public int MoveX;
public int MoveY;
public int MoveZ;

public bool World;

private bool IsGameRunning = false;

// Use this for initialization
void Start ()
{
IsGameRunning = true;
StartCoroutine(SpeedWaitForSeconds());
}

// Update is called once per frame
void Update () {

}

IEnumerator SpeedWaitForSeconds()
{
var delay = new WaitForSeconds(3);//define ONCE to avoid memory leak
while (IsGameRunning)
{
if (World == true)
{
transform.Rotate(TurnX * Time.deltaTime, TurnY * Time.deltaTime, TurnZ * Time.deltaTime, Space.World);
transform.Translate(MoveX * Time.deltaTime, MoveY * Time.deltaTime, MoveZ * Time.deltaTime, Space.World);
}
else
{
transform.Rotate(TurnX * Time.deltaTime, Random.Range(3, 300) * Time.deltaTime, TurnZ * Time.deltaTime, Space.Self);
transform.Translate(MoveX * Time.deltaTime, MoveY * Time.deltaTime, MoveZ * Time.deltaTime, Space.Self);
}

yield return delay;//wait
}
}
}


but that just rotate the object once each 3 seconds. and not rotating it all the time with speed changing every 3 seconds.

but now it's not rotating for 3 seconds it rotating every 3 seconds.

better to describe what I want is like intervals. The object should spin all the time nonstop like i Update but then each 3 seconds to change for a random speed.

for example spin at speed 5 ....after 3 seconds spin at speed 77 ....after 3 second spin at speed 199

public class Turn_Move : MonoBehaviour {
public int TurnX;
public int TurnY;
public int TurnZ;

public int MoveX;
public int MoveY;
public int MoveZ;

public bool World;

int randomNumber;

// Use this for initialization
void Start () {
InvokeRepeating("GetRandomNumber",0,5);
}

// Update is called once per frame
void Update () {
if (World == true) {
transform.Rotate(TurnX * Time.deltaTime,TurnY * Time.deltaTime,TurnZ * Time.deltaTime, Space.World);
transform.Translate(MoveX * Time.deltaTime, MoveY * Time.deltaTime, MoveZ * Time.deltaTime, Space.World);
}else{
transform.Rotate(TurnX * Time.deltaTime, randomNumber * Time.deltaTime,TurnZ * Time.deltaTime, Space.Self);
transform.Translate(MoveX * Time.deltaTime, MoveY * Time.deltaTime, MoveZ * Time.deltaTime, Space.Self);
}
}

void GetRandomNumber()
{randomNumber = Random.Range(3,300);}}


You can try this.

• Could you please explain your solution? – lvictorino May 4 '20 at 6:10
• Is it what you are looking for? or I misunderstood the question? – Navdeep May 4 '20 at 12:53
• I'm not the one who asked. I just think this is a site where people come to learn and improve their knowledge. Therefore copy/paste some code without any comment or explanation is not helpful in that sense. – lvictorino May 4 '20 at 12:55
• I didn't copy past the question. What happening was Random.Range(3,300) was called in every frame, but what he want - a random number that will stay for 5 sec(lets assume). So I am changing the random number by using "InvokeRepeating("GetRandomNumber",0,5);" this will change the number after 5 sec. – Navdeep May 4 '20 at 12:59
• Thanks, it's just what I asked for: some explanation for the poster to understand his/her mistake. Thanks for them. – lvictorino May 4 '20 at 13:05
