I am making a matchmaking system. My current function matched the players with a 20 difference in weight. As you can see on the result of my snippet, 1900 vs 1920 has been matched because i declared a different = 20,. Now my target is to make a dynamic different. I want to pass my textbox value to my different. I want to match player 2 and player 3. They do have 30 difference in weight.
If I type 30 on my textbox. Player 2 and Player 3 should be matched
. How can i achieve this? Any help will be appreciated. Thank you.
var difff = document.getElementById('diff'); // I have tried also to set a variable here to get the textbox value and pass it to my "different = difff" but it is not working.
const source = [
{
entryID: 1,
entryName: "player1",
weight: 1900,
},
{
entryID: 2,
entryName: "player2",
weight: 1920,
}, {
entryID: 3,
entryName: "player3",
weight: 1950,
},
];
function combine(
data = [],
different = 20, // I have tried to change the "20" to my id "difff" So i can pass my textbox's value but it is not working.
maxGroupSize = 2,
sortedStatement = (a, b) => a.weight - b.weight
) {
const sortedData = [...data].sort(sortedStatement); // "weight" must be in ascending order
const dataGroups = sortedData.reduce((acc, item) => {
const findedAccItem = acc.find(
(accItem) =>
accItem.length < maxGroupSize && // if the array is not filled
accItem[0].weight + different >= item.weight && // and if the minimum is in the acceptable range
!accItem.find((obj) => obj.entryName === item.entryName /* || obj.entryID === item.entryID */) // and if there are no matches
);
if (findedAccItem) {
findedAccItem.push(item);
} else {
acc.push([item]);
}
return acc;
}, []);
const namedDataGroups = dataGroups.reduce((acc, item, index) => {
// added an index as a prefix because the keys can match
const key = [index, ...item.map((item) => item.weight)].join("_");
acc[key] = item;
return acc;
}, {});
return namedDataGroups;
}
// default example
console.log("Example #1: ", combine(source));<input id="diff" type="number" value="20"/> // I need to pass this on my script.
