Changing the skybox material programmatically in Unity

I’m using this simple script after attaching it to UI Buttons to change my skybox materials. Let’s say we have two skybox materials with two UI Buttons to switch between them.

Here is the script:

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

public class ChangeSky : MonoBehaviour {

	public Material sky1;
	public Material sky2;

	public void SkyOne(){
		RenderSettings.skybox = sky1;
	}

	public void SkyTwo(){
		RenderSettings.skybox = sky2;
	}
}

 

Unity click and drag script to rotate camera

Just googling around to find how to rotate camera with mouse click and drag. Thanks to this link: https://answers.unity.com/questions/1189946/click-and-drag-to-rotate-camera-like-a-pan.html

This code is originally taken from that link:

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

public class CamRotate : MonoBehaviour {

	public float speed = 3.5f;
     private float X;
     private float Y;
 
     void Update() {
         if(Input.GetMouseButton(0)) {
             transform.Rotate(new Vector3(Input.GetAxis("Mouse Y") * speed, -Input.GetAxis("Mouse X") * speed, 0));
             X = transform.rotation.eulerAngles.x;
             Y = transform.rotation.eulerAngles.y;
             transform.rotation = Quaternion.Euler(X, Y, 0);
         }
     }
}

Then I made a slight changes to clamp vertical camera rotation:

if(Input.GetMouseButton(0)) {
			transform.Rotate(new Vector3(Input.GetAxis("Mouse Y") * speed, -Input.GetAxis("Mouse X") * speed, 0));
			X = transform.rotation.eulerAngles.x;
			if (X > 60.0f && X < 70.0f)
				X = 60.0f;
			if (X < 300.0f && X > 290.0f)
				X = 300.0f;
			Y = transform.rotation.eulerAngles.y;
			transform.rotation = Quaternion.Euler(X, Y, 0);
		}

 

JavaScript random numbers examples

Generating random numbers is a common thing in programming. Here is some examples in JavaScript:

//Basic Random
Math.random();
//From 0 to specific number
Math.random() * 10;
//Removing decimals
Math.floor(Math.random() * 10);
//Random between 5 and 10
Math.floor(Math.random() * 5) + 5;
//Random between 5 and 10 (included 10)
Math.floor(Math.random() * 5) + 6;
