How to see where the camera is facing in 3d? [closed]

i’m trying to make a game, inspired from minecraft.
it is for the mobile and i can already look around in the 3d space, but how can i let the code know where the middle of the 3d camera is?
i have tryed multiple things but they just stick with one number… because the camera is not moving at the moment.

the only thing i can think about is i need a combination of where the camera is and where the camera is looking.

I’m still having the same problem… also, looks like i only can place 2 coordinates at the place command, that will also be a problem when doing things in 3d.

i give up. i go to try using another game develop app.
