Mobile game (touch input, building, static camera)

Hi,

I’m trying to create a simple mobile game as an example. The concept is that I spawn objects on the screen. When the player touches the object, it will be destroyed. I can do this, but there are some things that I don’t know are my solutions right.

Player Controller

Do I need to have a player controller? Basically, I’m not controlling anything. If not, how I can delete/disable it? Is this even necessary?

Camera

I would like to have a static camera. I created a Camera BP and to assign it as default camera I needed to set “Auto activate for Player” to “player 0”. But I don’t know what this means? Is this the way handle this?

Objects

I created BP and added “On Touch Begin”. Is this right way to handle this?

Black dot when testing on mobile device

There is black dot in the center of the screen when testing the game on mobile. But it’s not there when running in PIE. What is that? Currently I just have object to be touched, background and a camera in outliner. And how I delete that black dot?
