“This is the 14th day of my participation in the Gwen Challenge in November. Check out the details: The Last Gwen Challenge in 2021.”

📢 preface

I briefly wrote two articles on how to switch skyboxes between Unity and code

Ordinary switch sky box or very simple, that can not meet my ideas!

Then this article has written a simple example to do a slightly fancier skybox switch example!

🍉 Skybox click on the rotation to switch

So let’s look at one of the things that’s implemented, just in case I don’t see what I meanBecause I wanted to have a skybox that could be switched at any time in the scene, I came up with this simple solution

Switch skyboxes by displaying a few balls with their own skybox material in the scene and clicking on them.

The following production steps, for the novice will show each step, very simple to learn!

🏳️🌈 Step 1: Simply build a scenario

Let’s build a scene in the scene to make our example more fun

I’m going to randomly place a plane and four little ballsAnd then find oursSkybox material ball 和 Picture of sky boxDrag it directly onto the ball!

So the ball has color

🏳️🌈 Step 2: click the ball through the code to switch the sky box

The code for this step is also very simple. We talked about how to switch skyboxes in code in the previous article

So here directly on the code, the following code is to click the ball to switch the sky box code, the previous article also said!

public class skyDemo1 : MonoBehaviour.IPointerDownHandler
{
    public Material skyMaterial;// Skybox material
    
    // Click the ball's callback
    public void OnPointerDown(PointerEventData eventData)
    {
        // Toggle skyboxesRenderSettings.skybox = skyMaterial; }}Copy the code

Then we hung the script on each ball and added our own skybox material to it

As follows:

At this time we can click on each ball to switch the sky box!

🏳️🌈 Step 3: Spin the ball

This step is easy, but there are many ways to implement rotation in Unity, which I won’t cover here

Transform.RotateAround(Vector3,Vector3,float);

  • The first parameter: the center point of rotation
  • Second argument: some axis at the center point
  • The third parameter: the speed of rotation

Add the code for the ball rotation in script skyDemo1, using the API method for the rotation described above

The complete code is as follows:

using UnityEngine;
using UnityEngine.EventSystems;

public class skyDemo1 : MonoBehaviour.IPointerDownHandler
{
    public GameObject skyCenter;
    public Material skyMaterial;// Skybox material

    public void OnPointerDown(PointerEventData eventData)
    {
        // Toggle skyboxes
        RenderSettings.skybox = skyMaterial;
    }

    void Update()
    {
        Revolution();
    }

    public void Revolution()
    {
        // Keep rotating at one speed around some axis at some central point
        transform.RotateAround(skyCenter.transform.position, skyCenter.transform.up, Time.deltaTime * 50); }}Copy the code

Then mount the script into the scene!

The implementation effect is as follows:

💬 summary

A simple switch sky box effect is achieved ~

This gives it a slightly more advanced feel, of course this is only the simplest switching effect, but it is much better than the original effect

Isn’t it easy? If you have a better idea, you can give me some suggestions

I also want some better ideas!!
