Calculate a vertical and horisontal angles

#calculate the horizontal angle
var horizontal_rotation: float = rad2deg(
    Vector2(bot_pos.x, bot_pos.z).angle_to_point(
    Vector2(player_pos.x, player_pos.z))
    + bot_rotation.y) - 90
#constrain the angle between -180 and 180 to be easyer to use
if horizontal_rotation < -180:
    horizontal_rotation += 360
elif horizontal_rotation > 180:
    horizontal_rotation -= 360

#calculate the vertical angle
var vertical_rotation: float = rad2deg(
    Vector2(bot_pos.y, bot_pos.z).angle_to_point(
    Vector2(player_pos.y, player_pos.z))
     + bot_rotation.x) - 90
#and constain it
if vertical_rotation < -180:
    vertical_rotation += 360
elif vertical_rotation > 180:
    vertical_rotation -= 360
