-- first we define a local variable i and j - these are used to check if the player has really ment to press the button. If you don't have this

-- to press the button for 7 dt's to get the function to change states and play the sound. i is one way j is the other.
-- second we create an object joysticks that contains the input data from the gamepad/joystick.
-- next we check joysticks to see if either button has been pressed? this is a bool value.
-- it checks if the back shoulder is pressed left or right, it then sets current_screen counter
-- to an updated value based on the modular derived from the length of the screens table.
-- Next I play a sound efect for feedback for the player when they hit the button. This should really not be hardcoded but should be found
-- in a table thats loaded at the start of the program to enable greater flexability. Will implement this later. As it makes updating the
-- code much easyer where I can update all of the sound effects for buttons in one place instead of all over the program.
-- the modular is hard coded, this is a mistake and it should update from a configuration table at the start of the program to enable
-- greater flexability. Will fix this later.
-- Finally we clear the j and i variables - otherwise you have a messy variable left. Its a little bit obsessive as normally this would not matter
-- but its nice to keep things tidy.
