Migrating old tutorial project (BEVY)

Making a game for the christmas edition jame gam !

Of course using the language rust for the bevy game engine (that I have very little experience with).

Now I have found this neat tutorial series that I've followed along for a while and I start to notice that a lot of the stuff he uses is depricated in the current version of Bevy. So now I'm stuck migrating all his old code to the newest version. Why do all this, well because the new version firstly adds easy chromatic abberation (looks really cool) and also makes dealing with gamepads (controllers) much easier (though I knew the old systems in and outs so I'll need to relearn the new systems ways).

In the middle of all of this migrating old code I notice that the way the engine now implements cameras is really different. Apparently all you have to do is just spawn a "Camera3D" and it should work. But because this is so new there are literally ZERO examples out there on how to properly implement it so my stupid ass has no clue how I'm supposed to migrate this properly. The only link I can find on the new system is this wiki link that has no examples on how to implement it the way that you used to (and gives no useful inputs for what I should plug in either) and the migration guide just says that the new required components will be inserted automatically but I still can't get it to goddamn work :(

I think there is some solution though, and if that is that I'll have to be the only example out there than so be it :P
