You're defining TDS, which is a string.
Then you're saying Textdraw1[playerid] = TextdrawCreate(...).
And then you want to modify the TDS string.
So, this is the correct code:

pawn Код:

//Make sure Textdraw1 is defined as: new Text:Textdraw1[MAX_PLAYERS];
new tds[128];
    format(tds, sizeof(tds), "Score: %d",GetPlayerScore(playerid));
    Textdraw1[playerid] = TextDrawCreate(276.000000, 391.000000, tds);
    TextDrawBackgroundColor(Textdraw1[playerid], 255);
    TextDrawFont(Textdraw1[playerid], 1);
    TextDrawLetterSize(Textdraw1[playerid], 0.500000, 1.799999);
    TextDrawColor(Textdraw1[playerid], -1);
    TextDrawSetOutline(Textdraw1[playerid], 0);
    TextDrawSetProportional(Textdraw1[playerid], 0);
    TextDrawSetShadow(Textdraw1[playerid], 1);

But there's still a problem, you will have to create the textdraw at "OnGameModeInit".

pawn Код:

public OnGameModeInit()
{
//blablabla
    foreach(Player, playerid)
    {
        Textdraw1[playerid] = TextDrawCreate(276.000000, 391.000000, "_");
        TextDrawBackgroundColor(Textdraw1[playerid], 255);
        TextDrawFont(Textdraw1[playerid], 1);
        TextDrawLetterSize(Textdraw1[playerid], 0.500000, 1.799999);
        TextDrawColor(Textdraw1[playerid], -1);
        TextDrawSetOutline(Textdraw1[playerid], 0);
        TextDrawSetProportional(Textdraw1[playerid], 0);
        TextDrawSetShadow(Textdraw1[playerid], 1);
    }
    return 1;
}
//I hope you have a login system which will give them their score.
//If you want to update your textdraw frequently, set a timer.
public OnPlayerSpawn(playerid)
{
    new tds[128];
    format(tds, sizeof(tds), "Score: %d",GetPlayerScore(playerid));
    TextDrawSetString(Textdraw1[playerid], tds);
    TextDrawShowForPlayer(playerid, Textdraw1[playerid]);
     return 1;
}

Edit: lol, Calgon was too fast.
