Hi, I want an idea for a game that I’m making, I want it to be a 3D FPS. Any ideas?
(By the way, I’m a 9 year old so don’t make it too complicated)
I would really suggest you start with 2d.
It would give you the ideas, how things work. And of course bring some familiarity with Unity engine and it’s APIs.
Do some prototypes. Like even separate mini projects.
Make shooting gun, make some animation. Make some effects. Make character controller and move your Avatar. Make UI, etc.
You will learn, how to move stuff and how to interact with them.
At least from that point, it will be easier for you, to venture into 3D world in future.
While 3D is not that much different in many aspects from 2D, it still brings extra complexity on top.
So learning principles is good starting point.
