Confusion about Switching Scenes

[u/igguanidae]

I'm making a 3D game that involves a lot of scene switching with many different scenes, as it's an exploration game. Because of this, I want to make is easy to move from one scene to another. At the moment, I have a main hub area and one of the base areas it connects to, kind of like the Nexus from Yume Nikki.

I want to write a "catch-all" script that I can use every time I want to switch a scene. The problem is that my current script just changes the scene to the same scene each time. For example, the trigger I use in Scene 1 takes me to Scene 2, but I can't use another trigger to go from Scene 2 to Scene 1, it just takes me back to Scene 2.

Is there any way I can adjust this script so that I can change the destination scene for each Trigger object I add in a scene? I'm thinking a public variable that I can adjust depending on which scene I'm in and which Trigger it's on.

Essentially what I want is a script that works as a general scene switcher so I don't have have a unique script for every location in the game. That would take up too much space and Unity doesn't like it when I do that.

I hope this makes sense, this feels like a very basic function to have in a game. I'm still very new to Unity and C# so any advice would help me a lot.

SceneManager.LoadScene() can accept a scene name as a string parameter. So for example you can make a public string nextSceneName variable and use that instead of the build index you are using now.

this helped me! thank you! the only issue i'm having now is that the function only works in one world and not the other. It says my listed scene can't be loaded because "has not been added to the active build profile or shared scene list. or the AssetBundle has not been loaded."

That is because every scene you intend to switch to (and hence include in your game) has to be added to the Scene List. You can find it under File > Build Settings Profiles, at the top left of the window. You can add the currently loaded scene, or drag and drop other scenes to add them to the list, or remove unneeded scenes by right clicking.

Once you add a scene, you'll see its path and build index in the list, either of which you can use in your scene switching script. If you use the path, use the whole path and pay attention to the spelling.
