Question Want to randomly change color of object every 2 seconds

Hello, I am trying to randomly change the color of a cube object every 2 seconds. As of right now, the colors are changing randomly, but I can't get them to change every 2 seconds. Instead, they are changing very rapidly. Way too quickly. Any help?

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class Cube : MonoBehaviour
6. {
7.    
8.     public MeshRenderer Renderer;
9.     private float startDelay = 2.0f;
10.     private float repeat = 1000.0f;
11.    
12.     void Start()
13.     {
14.         transform.position = new Vector3(3, 4, 1);
15.         transform.localScale = Vector3.one * 1.3f;
16.        
17.        
18.     }
19.    
20.     void Update()
21.     {
22.  
23.         InvokeRepeating("changeColor", startDelay, repeat);
24.         transform.Rotate(10.0f * Time.deltaTime, 0.0f, 0.0f);
25.     }
26.  
27.     void changeColor()
28.     {
29.         Material material = Renderer.material;
30.        
31.         material.color = new Color(Random.Range(0.0f, 1.0f), Random.Range(0.0f, 1.0f), Random.Range(0.0f, 1.0f));
32.  
33.     }
34. }
35.  

 

You should only be calling InvokeRepeating once. You're calling it every frame.

 

put

Code (CSharp):

1. InvokeRepeating("changeColor", startDelay, repeat);

in start, then it gets called once

 

Not a huge fan of black boxes like

InvokeRepeating()

.

It provides virtually zero useful value in today's environments.

Even worse when they accept a string for the function, which could have typos.

Just use a counter.

Code (csharp):

1. private float yet;
2. private float interval = 2.0f;

]

and...

Code (csharp):

1. void Update()
2. {
3.   yet += Time.deltaTime;
4.   if (yet >= interval)
5.   {
6.      yet -= interval;         // or set it to zero, your choice
7.      changeColor();
8.   }
9. }

And if you have a TON of these, wrap them up in a CallPeriodically class you make yourself, sorta like this CallAfterDelay() class, which could be trivially combined with the above code:

Whoops! You're right. This fixed it. Thank you.
