Example: Sending Latest Data To Client

To get the latest data for a client, we send an empty request every update and simply poll the data that we want.

In this example, we will see how many users are connected to the server.

For the server:

lovernetlib = require('lovernet')
lovernet = lovernetlib.new{type=lovernetlib.mode.server}
lovernet:addOp('q') -- (q)uery .. use single character to reduce bandwidth
lovernet:addProcessOnServer('q',function(self,peer,arg,storage)
  local count = 0
  for user_index,user in pairs(self:getUsers()) do
    count = count + 1
  end
  return count
end)

function love.update(dt)
  lovernet:update(dt)
end

For the client:

lovernetlib = require('lovernet')
lovernet = lovernetlib.new()
lovernet:addOp('q')

function love.update(dt)
  lovernet:pushData('q')
  lovernet:update(dt)
end

function love.draw()
  if lovernet:getCache('q') then
    love.graphics.print('Connected users:'..lovernet:getCache('q'))
  end
end
