You need this function:

pawn Код:

stock strreplace(string[], find, replace)
{
    for(new i=0; string[i]; i++) {
        if(string[i] == find) {
            string[i] = replace;
        }
    }
}

And....then.

pawn Код:

stock GetName(playerid)
{
    new string[MAX_PLAYER_NAME];
    GetPlayerName(playerid,string,sizeof(string));
    strreplace(string,'_',' ');
    return string;
}
