PlayerInfo[playerid][pExp] needs to be a float point.

EDIT: Try this dunno if it would work

pawn Код:

new Bar:vhealth[MAX_PLAYERS];
new Float:ExpBar;
forward ProgressBar();
public ProgressBar() //I prefer not to use OnPlayerUpdate with textdraws
{
    for(new playerid; playerid < MAX_PLAYERS; playerid++) //I recommend foreach(Player, playerid)
    {
        ExpBar = PlayerInfo[playerid][pExp];
        SetProgressBarValue(vhealth[playerid], ExpBar);
        UpdateProgressBar(vhealth[playerid], playerid);
    }
}
