public OnPlayerUpdate(playerid)
{
    new iCurWeap = GetPlayerWeapon(playerid); // Return the player's current weapon
    if (iCurWeap != GetPVarInt(playerid, "iCurrentWeapon")) // If he changed weapons since the last update
    {
        // Lets call a callback named OnPlayerChangeWeapon
        OnPlayerChangeWeapon(playerid, GetPVarInt(playerid, "iCurrentWeapon"), iCurWeap);
        SetPVarInt(playerid, "iCurrentWeapon", iCurWeap);//Update the weapon variable
    }
    return 1; // Send this update to other players.
}

    {
        // Player health has changed since the last update -> server, so obviously thats the thing updated.
        // Lets do further checks see if he's lost or gained health, anti-health cheat? ;)

        if (fHealth > GetPVarFloat(playerid, "faPlayerHealth"))
        {
            /* He has gained health! Cheating? Write your own scripts here to figure how a player
            gained health! */

warning

This callback is called, on average, 30 times per second, per player; only use it when you know what it's meant for (or more importantly what it's NOT meant for). The frequency with which this callback is called for each player varies, depending on what the player is doing. Driving or shooting will trigger a lot more updates than idling.
