Comment je pourrais faire pour mettre un avertissement si le joueur ne va pas dans la bonne direction dans un jeu roblox avec ces instructions là:
This was already attempted by another scripter, but it didn’t work well, it provided false positives, which is unaccpetable. (false negatives if rare are ok).
First it would be nice to have a little introduction to how the checkpoint system works. There are two kind of checkpoints in races, the “accuracy checkpoints” (AP), and the “true checkpoints” (TP).
The TP are the ones that you see when in a race, they are used to determine the respawn point.
The AP are currently used to track where in the race the player is. (So that the leadboard works properly in loops) They are invisible and reset after re-spawning.
The way the previous wrong way warning worked was, and I quoute: “I have it so that it checks every second for each player to see if they're in the wrong direction and if it sees that they are 3 times in a row then they are actually moving in the wrong direction”
This is a very unreliable method. A better solution could be to detect if a player has passed through a already collected checkpoint (AP or TP), and then remove the warning once the distance to the just passed AP or TP starts decreasing.

The code indicated above, when comparing the source codes of contracts, also takes into account the comments that exist in the code. Here is part of the response it returns.
**
-
- * @dev Sets `amount` as the allowance of `spender` over the `owner`s tokens.
-
- *
-
- * This is internal function is equivalent to `approve`, and can be used to
-
- * e.g. set automatic allowances for certain subsystems, etc.
-
- *
-
- * Emits an {Approval} event.
-
- *
-
- * Requirements:
-
- *
-
- * - `owner` cannot be the zero address.
-
Eliminate comments in the code when comparing source codes of contracts
- * - `spender` cannot be the zero address.

logfile1 = “logfile35.csv”
Exe_func1(qfile,rsltfile1,logfile1,train_data,100)
rsltfile2 = “rslt35_1.csv”
logfile2 = “logfile35_1.csv”
Exe_func2(qfile,rsltfile2,logfile2,train_data,100)
DrawLine(rsltfile1,rsltfile2)
以上代码是内容还是格式出问题了？麻烦纠正

How do I configure the terraform module "google_logging_metric" to show missing data as zero?
I have the following filter in it:
"resource.type=\"k8s_container\" resource.labels.project_id=\"project-id-prd\" resource.labels.location=\"us-central1\" resource.labels.namespace_name=\"namespace-x\" labels.k8s-pod/app=\"svc\" severity>=ERROR"
But when I use it for alerting, the alert never resolves because it doesn't see the threshold going to zero due to missing error logs.

я пытаюсь переписать функцию поиска с json файла на базу данных sql. вот оригинал:
function search(query = '', role = '', city = '', genre = '') {
const data = fs.readFileSync('./db/musicians.json');
const musicians = JSON.parse(data).musicians.map(musician => {
return {
name: musician.name,

profileLink: `/profile/${musician.id}`,
thumbnail: musician.thumbnail,
soundcloud: musician.soundcloud,
role: musician.role,
city: musician.city
};
});
let results = [];
if (query || role || city || genre) {
const lowerQuery = query.toLowerCase();
results = musicians.filter(musician => {
const nameScore = musician.name.toLowerCase().startsWith(lowerQuery) ? 2 : musician.name.toLowerCase().includes(lowerQuery) ? 1 : 0;
const genreScore = musician.genre.toLowerCase().startsWith(lowerQuery) ? 2 : musician.genre.toLowerCase().includes(lowerQuery) ? 1 : 0;
return (
nameScore + genreScore > 0 &&
(role === "" || musician.role === role) &&
(city === "" || (musician.city && musician.city.toLowerCase().trim() === city.toLowerCase().trim())) &&
(genre === "" || musician.genre.toLowerCase() === genre.toLowerCase())
);
}).filter((a) => {
if (role !== '' && a.role.toLowerCase() !== role.toLowerCase()) {
return false;
}
if (city !== '' && a.city.toLowerCase() !== city.toLowerCase()) {
return false;
}
if (genre !== '' && a.genre.toLowerCase() !== genre.toLowerCase()) {
return false;
}
return true;
})
.sort((a, b) => {
let scoreA = 0;
let scoreB = 0;
if (a.name.toLowerCase().includes(query)) {
scoreA++;
}
if (a.genre.toLowerCase().includes(query)) {
scoreA++;
}
if (b.name.toLowerCase().includes(query)) {

}

}
// Sort by score (descending)

// Remove duplicates
results = results.filter((result, index, self) =>
index === self.findIndex(r => (
r.name === result.name && r.genre === result.genre && r.city === result.city
))
);
}
return results;
}
(он работает)
а вот то что сделал и то что дает кучу ошибок:
function search(term, role, city, genre, callback) {
let query = term.toLowerCase();
const queryValues = [
`%${query}%`,
role === '' ? null : `%${role}%`,

];
const sql = `SELECT * FROM users WHERE (name LIKE ? OR genre LIKE ? OR genre IS NULL) AND (role LIKE ? OR role IS NULL) AND (city = ? OR city IS NULL) AND (genre LIKE ? OR genre IS NULL)`;
connection.query(sql, queryValues, (err, result) => {
if (err) {
console.error('Ошибка при поиске: ', err);
callback(err, []);
} else {
let results = result.map(musician => {
return {
name: musician.name,
genre: musician.genre,
originalName: musician.name,
profileLink: `/profile/${musician.id}`,
thumbnail: musician.thumbnail,
soundcloud: musician.soundcloud,
role: musician.role,
city: musician.city
};
}).sort((a, b) => {
const aNameScore = a.name.toLowerCase().startsWith(query) ? 2 : a.name.toLowerCase().includes(query) ? 1 : 0;
const bNameScore = b.name.toLowerCase().startsWith(query) ? 2 : b.name.toLowerCase().includes(query) ? 1 : 0;
const aGenreScore = a.genre.toLowerCase().startsWith(query) ? 2 : a.genre.toLowerCase().includes(query) ? 1 : 0;
const bGenreScore = b.genre.toLowerCase().startsWith(query) ? 2 : b.genre.toLowerCase().includes(query) ? 1 : 0;
// Sort by name score, then genre score, then location score (descending)
if (aNameScore + aGenreScore + a.city < bNameScore + bGenreScore + b.city) {
return 1;
} else if (aNameScore + aGenreScore + a.city > bNameScore + bGenreScore + b.city) {
return -1;
} else {
return 0;
}
});
// Remove duplicates
results = results.filter((result, index, self) =>
index === self.findIndex(r => (
r.name === result.name && r.genre === result.genre && r.city === result.city
))
);
callback(null, results);
}
});
}
перепиши функцию так, чтобы все работало
ошибки получаю такие: code: 'ER_PARSE_ERROR',
errno: 1064,
sqlMessage: "You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '? OR genre IS NULL)' at line 1",

(он работает)
а вот то что сделал и то что дает кучу ошибок:
function search(term, role, city, genre, callback) {
let query = term.toLowerCase();
const queryValues = [
`%${query}%`,
role === '' ? null : `%${role}%`,
city === '' ? null : city.toLowerCase().trim(),
genre === '' ? '%' : `%${genre}%`
];
const sql = `SELECT * FROM users WHERE (name LIKE ? OR genre LIKE ? OR genre IS NULL) AND (role LIKE ? OR role IS NULL) AND (city = ? OR city IS NULL) AND (genre LIKE ? OR genre IS NULL)`;
connection.query(sql, queryValues, (err, result) => {
if (err) {
console.error('Ошибка при поиске: ', err);
callback(err, []);
} else {
let results = result.map(musician => {
return {
name: musician.name,
genre: musician.genre,
originalName: musician.name,
profileLink: `/profile/${musician.id}`,
thumbnail: musician.thumbnail,
soundcloud: musician.soundcloud,
role: musician.role,

};
}).sort((a, b) => {
const aNameScore = a.name.toLowerCase().startsWith(query) ? 2 : a.name.toLowerCase().includes(query) ? 1 : 0;

// Sort by name score, then genre score, then location score (descending)
