Code:  
Client script: 
local function MonsterspawnRequests(mosterId)
  PackageHandlers.sendClientHandler("MonsteSpawn",{mosterId}, function()
      print("A monster build request has been sent")
  end)
end

summonBar.Moster_1.onMouseClick = function(instance, window)

    goldText:setText("Gold："..gold) 
    MonsterspawnRequests(monstersButtons[1].id)

Just finished a whole day scripting....A little bit tired but happy with the progress. Need some light music to relax, any recommendation?

local DBHandler = require "dbhandler"

PackageHandlers.registerServerHandler("LevelChangeServer", function(player, packet)
    DBHandler:setData(player.platformUserId, 51, packet[1],true)
    World.CurWorld.SystemNotice(1, "level up:  "..string.format("%.0f",packet[1]), 40)
end)

PackageHandlers.registerServerHandler("ExpChangeServer", function(player, packet)
    DBHandler:setData(player.platformUserId, 52, packet[1],true)
end)
