// < Packet: 1 >
// + id: int32 = -1
// + amount: int32 = null
// + bonuses: array = null

// SERVER-SIDE
if (SERVER_SIDE) {
    addEventHandler("onPlayerJoin", function (pid) {

            TradeItemMessage(5, 32),
            TradeItemMessage(23, null, [
                BonusItemMessage(BonusType.DAMAGE, 10),
                BonusItemMessage(BonusType.HEALTH, 50)
            ]),
        ]

        foreach (message in items) {
            message.serialize().send(pid, RELIABLE)
        }
