Thanks! I had a look at the code and I saw this:

pawn Код:

public OnPlayerCommandText(playerid, cmdtext[])
{
    if (strcmp("/sync", cmdtext, true, 10) == 0)
    {
        new Float:X;
        new Float:Y;
        new Float:Z;
        TogglePlayerControllable(playerid,1);
        GetPlayerPos(playerid,X,Y,Z);
        SetPlayerPos(playerid,X,Y,Z+2);
        ClearAnimations(playerid);
        PlayerPlaySound(playerid, 1137, X, Y, Z);
        SendClientMessage(playerid,0x00FFFFFF,"You are synced.");
        return 1;
    }
    return 0;
}

I'm not able to test it to a local host because I will never be desynced, but it happens when I lag in servers with a lot of people. So, it basically unfreeze a player, set his position 2 meters higher and clear the animations will make the player be synced again? If it does, nice.

Note; the lenght of the command "/sync" is 5, not 10.
