Add a scene into another scene (kind of overlay) ?

Hi there !

I'm searching for a while on the forums and Google and could not figure out if this is possible using Unity. Basically, I have built a game in one scene (let's call it gameScene). I use a device that recognizes my hand and the gameplay of the game is based on the movements I'm doing. The SDK of the device provides another scene where I can see my hand with fingers (let's call it handScene).

What I would like is to ability to play my game in gameScene while having a little overlay/area (I'm not sure if there is another word for that) that would display the handScene inside, so I can visually demonstrate that I can read to movement of the hand to interact with the game.

Naturally, I would call that inserting a scene inside another, but I'm sure this is not the right vocabulary, since I could not find any helpful resources out there.

Many thanks for you help !

Cheers

 

Unity usually refers to it as multi-scene. Here is the document entry for editing multiple scenes.

https://docs.unity3d.com/Manual/MultiSceneEditing.html

For loading them at runtime you'd use the SceneManager but with LoadSceneMode set to Additive. You can load them, set them active/inactive, unload them, and so on through the SceneManager.

Hi @ZenLulz !
I know it has been some years since you posted this, but I was wondering if you figured out a way of doing so. For what I understood you wanted a scene to render ontop of another scene and at the same time for both scenes to be running. I am trying to do the same thing (if what you were trying to do was what I described). Either way, do you know of a way that I could do that?
Thanks a lot!

 

It's been a while, but I just read the article and it fixed the problem. You use scene manager.

Code (CSharp):

1. using UnityEngine.SceneManagement;
2.  
3. public static class SceneSwitcher
4. {
5.     public static void LoadSceneOnTop(Scene scene)
6.     {
7.         SceneManager.LoadScene(scene.ToString(), LoadSceneMode.Additive);
8.     }
9.  
10.     public static void UnLoadSceneOnTop(Scene scene)
11.     {
12.         int n = SceneManager.sceneCount;
13.         if (n > 1)
14.         {
15.             SceneManager.UnloadSceneAsync(scene.ToString());
16.         }
17.     }
18. }
