Updated player.lua with physics

player.lua

  -- Create a player table
  player = {}
  -- Create a width (for later drawing)
  player.width = 20
  -- Create a height (for later drawing)
  player.height = 20
  
  -- Create a new physics body in the world and make it "dynamic"
  -- The new coordinates will be where the 'body' is going forward.
  -- Any time (like for drawing) the x,y is needed use getX() and getY()
  player.body = love.physics.newBody( world, 100, 100, "dynamic" )
  
  -- Make a rectangle shape with: 
  --  Starting at 100, 100 (player.body:getX() and player.body:getY() )
  --  a width of player.width
  --  a height of player.height
  player.shape = love.physics.newRectangleShape(player.body:getX(), player.body:getY(), player.width, player.height) 
  
  -- Attach the shape to the body
  player.fixture = love.physics.newFixture(player.body, player.shape, 1);
