unity movement script 2d

//This is a script for a 2D plataformer type of movement.
//This script includes the movement, flipping the player and a ground check if you need one.
/*
  This is a two in one grepper answer, 
  the script flips the player by rotating it,
  and when it rotates, if the camera 
  is attached to the player the normal way, 
  its going to rotate the hole camera.
  and the only way to fix that bug is by making it so 
  the camera follows you with code, 
  if you scroll all the way down you can find the code that makes 
  the camera follow the player.
