  Just translate drawing away from the player's position.

  translate(-player.x, -player.y)
  

  (Note: for drawing the player, first you have to do resetMatrix() or translate(pkayer.x, player.y) to put it back in the center)

  I'm also confused with this. @SkyTheCoder could you give an example program?

  Here's an example of what I think @SkyTheCoder meant

  function setup()
      player=vec2(WIDTH/2,HEIGHT/2)--position of the player in the world
      origin=vec2(WIDTH/2,HEIGHT/2)--position the player will be drawn at
      print("tilt to move")
  end
  
  function draw()
      player = player-vec2(Gravity.x,Gravity.y)*10--move the player
      background(0)
      pushMatrix()--save the current transformation
      translate(player.x-origin.x,player.y-origin.y)--move screen in the opposite direction to player
      spriteMode(CENTER)
      sprite("SpaceCute:Background",origin.x,origin.y,WIDTH)--draw the ground
      popMatrix()--reset the transformation
      sprite("Planet Cute:Character Boy",origin.x,origin.y)--draw the player in the middle of the screen
  end
