Hello, I'm new to this and I wanted you to tell me how to make a score record, that is, when the player loses, a list of his current score is saved and then when he exceeds it, a new score appears

You can use the UserInfo class:
This takes the variable „score“ and updates the score field in UserInfo. It returns the highscore.
if(!UserInfo.isStorageAvailable()) {
System.err.println("Cannot save score!");
return -1;
}
UserInfo user = UserInfo.getMyInfo();
if(user.getScore() >= score)
return user.getScore();
user.setScore(score);
user.store();
return score;
the example gives me an error but what I mean is that when the player loses a list is saved with their current score and is updated when they get points and also the points system is simple the one I have
Why do you want to save a list?
And what error do yo get? You need to put that code into a method, for example public int updateScore(int score).
In the UserInfo class, you have limited amounts of storage available:
1x int "score"
10x int "int"
5x String "string", max length 50 chars
If your list is never longer than 10 items, you can just save entry by entry in the "int" fields. However, you should consider what exactly you need to save. Remember the only place you will need the stored values is in these cases:
- Compare whether the new score is greater than the saved score
- Show the high score
If you use a list during the calculation while the game is running, that is fine, but you should then try to reduce the list into a single value which, the higher it is, indicates a better score. That is easier to compare, easier to store, and easier to display.
But if you want to do that first approach of saving an array into UserInfo, this is a way to do it:
This does, however, not compare the values to the previous score (because I don't know how they should be compared).
It would really help if you would explain why you think you need a list, and what each entry of that list means.
public void storeArray(int[] array) {
UserInfo user = UserInfo.getMyInfo();
for(int i=0; i<array.length; i++)
user.setInt(array[i]);
user.store();
There is example code given within the documentation of the UserInfo class that should be sufficient for your needs (as far as saving new high scores).
The setInt method requires 2 parameters. Line 2 should be:
where the variable i, or the length of the array, cannot be greater than 10.
