Camera Moement with on screen buttons

Your question is about touchscreen or else?

not sure if I understand your question correctly, but you can change the camera angle in the function that receives the button signal.
e.g.

1. click top button sends "top_button_pressed" signal
2. "top_button_pressed" signal triggers "look_up()" function
3. in "look_up()", you rotate the camera to the new value - I think it's something like $Camera.rotate_y(0.5)

And how would I move the camera in a direction (let's just say towards the door)?

As Camera3D inherit from Node3D, you can set its global_position using a tween from its current/starting position to its final position.
