Simple oop problem

entities = {}

function entities:create(x,y,w,h,c)
  entity = {}
  entity.x = x or 0
  entity.y = y or 0
  entity.width = w or 1
  entity.height = h or 1
  entity = world:newRectangleCollider(entity.x,entity.y,entity.width,entity.height)
  if c then
    entity:setCollisionClass(c)
  else
    entity:setCollisionClass("wall")
  end


 entity.draw = function(self,path)
  local sprite = love.graphics.newImage("assets/images/pipe.png")
  love.graphics.draw(sprite,self.x,self.y)
end

  return entity
end
