The creation of this video started with a simple idea: I wanted to make a video showing people making metroidvanias how to handle scene transitions when they have multiple doors in each scene.
But...it kinda EXPLODED into this monster of a video.
SO! In this Unity tutorial, I wanted to show you how I handle everything in the most professional way I knew how - so basically, this video will show you how to handle: multiple doors, scene transitions, scene references and data persistence like a commercial game. And I say that with confidence, because these are the same systems I use in my metroidvania Veil of Maia.
I hope you enjoy!

@@uxxix 😭 I'm sorry, I'm gonna go full preach mode xD. Ignore it if is annoying: The more the pain the better we become. That's why most amazing people are those who have the most painful and unexpected moments and yet they find peace in going through these tough times and they shape who they are instead of becoming weak. So I'm sad for situation but I'm not worried. Positive will begin to form and show up if we accept these struggles and learn from them.

When having 2 PlayerInputs on the same scene, AutoSwitch no longer works because each Player Input "claims" a control scheme. My recommendation for the UserInput Class to work is, instead of adding a Player Input component to the UserInput Class gameobject and having a Static Reference to it, to have a Serialized Field private reference to the Player Input Component of the Player and get the InputActions references in Start instead of Awake to avoid null references.

This was a lot more complicated than I expected 😂. I did get a game transitioning from one scene to another while playing around with a few bits a few months ago, but I remember the coding being much simpler (though I imagine also a lot more limited than what you’ve set up, I.e. mine was just one door and it went from scene 1 to scene 2). I’ll have to watch this a couple more times I think to make sure I’m understanding it properly before I try to implement anything similar!

@Dedicatedfollower467 10 ай бұрын

Although I'm planning on moving away from Unity, I think the basic scripting principles behind this are really good and helpful!

Hey, the Scene Field class does not appear to work when it comes to renaming the scene. The script renames the scene in the string field only if the editor for the object is open.

For some reason, when I tried the new Input setup, the controls are no longer detected. Any idea what I might be missing. I copied the UserInput script and in Player.cs used, for example, moveInput = UserInput.MoveInput.x;.

Even if they try to walk back these changes, they'll just try them again but worse one, two, three years from now. Anyone starting a project in Unity now has to understand they're basically signing up to pay any arbitrary fee Unity invents in the future.

Do you think it's really worth to make all this shenanigans to work around "dont destroy on load" what if you just let it be gone, and have a player on every scene? I don't see a point in keeping stuff as the same object. except something like a music player

@Fenga 10 ай бұрын

the dont destroy on load is to keep state. If you destroy and reload each scene the reloaded object will have whatever value was saved in the scene. IE you cannot keep persistance between scene loads.

@@Fenga i don't feel like storing data on the game object itself is a good idea in most cases, only seems useful for music dont stop playing between scenes imo

Some useful information, but misleading title. A lot of simplifications: you should use async scene loading, use animations for scene transitions, very bad limitation with door enums, and so on.

@owencoopersfx 10 ай бұрын

I don’t think in this particular case that the door enum is a bad solution - enums can be bad when they might need to be expanded and you need to do more than a simple bool if the values are equal. As long as the check is just for equivalent value, then it’s easy to expand on it in the one place the enum is defined. Another solution over the enum would be ScriptableObjects. Make an SO type DoorID, and then you can just make the field holding that on each door readable and just check if the one assigned to the exit door matches that on the entrance door. But both are doing the same thing in essence.

Please, we've heard about your difficulties in making your games so you guys can fulfill your dream. Heck, I could even offer to give you a hand, no cost, to move to something else but please, don't stay in Unity. It's a risk and it could become your worst financial decision. I'm not joking.
