Take records from set and count how many records for each player id

Question

I'm making a leaderboard in my game and I have tiles with certain player ids assigned to them.

I need to take the following data (which is a set containing my 'Tile' records):

    [Tile[id=eeebeaa4e03c8910e5c17925439f1fa1abb,position=Vec[x=-11.0, y=6.0, z=73.0], player_id=1oyr8l], Tile[id=3c10969e83a61f44139d5dbeb8b41c9e,position=Vec[x=-12.0, y=6.0, z=73.0], player_id=1oyr8l], Tile[id=f51fd6f3eb407305a49bde1cb2cf44fe,position=Vec[x=-12.0, y=6.0, z=74.0], player_id=qX9Bh7]]

I want to format it into something like:

    1oyr8l: 2
    qX9Bh7: 1

Or in code form:

    public record Tile(String id, Vec position, String owner) {
    // irrelevant code here
    }

    private final Set<Tile> userTiles = getTiles() // dummy func but you get the idea

I want to take userTiles, which is a Set<Tile> and make it into the sorted & counted format I showed above in text format, but in the form of a HashMap, such as:

    HashMap<String,Integer> leaderboard = new HashMap<String,Integer>();

You might want to update react state when the component is mounted.

export const useIsMounted = (): { readonly current: boolean } => {
  const isMountedRef = React.useRef(false);
  React.useEffect(() => {
    isMountedRef.current = true;
    return () => {
      isMountedRef.current = false;
    };
  }, []);

  return isMountedRef;
};

You can create a hook just like the above one or you can prefer useIsMounted hook from this source in order to detect if the component is mounted. Then in your case, simply do the logic below.

if(isMounted.current) {
   yourSetStateAction()
}
