how to code a leaderboard
Paste in new code from Leaderboard GAS file Save (Enter a project name) Click: Run > setup An Authorization Dialog will appear. However, you may wish to verify constraints derived from those promises, because your code might be broken, or because you might copy your code later into a position where those promises might no longer hold. Design a Leaderboard class, which has 3 functions: addScore(playerId, score): Update the leaderboard by adding score to the given player’s score. Obviously, your mileage may vary. You could try it with a new or nontraditional programming language, or text editor, or keyboard layout. The Set ID of each leaderboard and leaderboard set is automatically prefaced with the grp. I will say that, if you do test things, make sure you’re testing them on the right input and are correct about what the expected output or behavior is. Opinions are mine and not of any employer, past or present. To be honest, I’m not sure if I can faithfully describe my strategy for reading AoC problems — it just goes by so quickly. To get a sense of the massive variety of approaches others have taken, you might scroll through the posts flaired with Upping the Ante in the subreddit. I have no idea what 2020’s calendar will bring, but cleaning up your code from previous days in case you need to reuse or modify it is probably not a bad idea. The second part is often a surprising twist on the first part, which keeps you on your toes and challenges you to keep your code moderately general or refactorable in a way that I think almost no other programming challenges do. Not terminating was actually the correct behavior for my program; I wasted a bunch of time debugging when there was nothing to debug. You can use your favorite text editor or ocular organs to manually preprocess the input, postprocess the output, or both. If you’re not sure what a function does exactly or what order its arguments go in, don’t use it without looking it up. Try to learn them. The following code shows how to set up a leaderboard_query: leaderboard::leaderboard_query leaderboardQuery; leaderboardQuery.set_skip_result_to_rank(10); leaderboardQuery.set_max_items(10); leaderboardQuery.set_order(sort_order::descending); Anyway, one particular feature Advent of Code has is a leaderboard, which you can get on by being one of the first 100 people worldwide to solve each puzzle. Near the start of AoC 2019, mcpower (reddit discussion) and Kevin Yap (reddit discussion) wrote some articles about how to do this, both of which are worth reading. The code is going to be something like this: users = [ ( "username", 5 ), ( "someone", 15 ), ( 'n00b', 0 )] # Sort user array users.sort (key= lambda a: a [ 1 ], reverse= True ) # Format the users leaderboard = map ( lambda user: user [ 0] + "| " + str (user [ 1 ]), users) # Output print ( "\n" .join (leaderboard)) Hopes this helps! So I can’t say much more than that there’s a balance to strike in terms of how aggressively you should skim. Displaying a leaderboard. Copy-paste code. But if you’re 100% confident about how your hacky code will work, or if you think the “best practices” alternative to your hacky approach is significantly more verbose, don’t hesitate. If we perform the operations like below − Leaderboard leaderboard = new Leaderboard (); leaderboard.addScore(1,73); // leaderboard is [[1,73]]; leaderboard.addScore(2,56); // leaderboard is [[1,73],[2,56]]; You can also just use a dictionary or hash map. There are lots of ways to do Advent of Code. let scores = [ {name: "Player 1", score: 300}, {name: "Player 2", score: 370}, {name: "Player 3", score: 500}, {name: "Player 4", score: 430}, {name: "Player 5", score: 340}, ]; function updateLeaderboardView() { let leaderboard = document.getElementById("leaderboard"); leaderboard.innerHTML = ""; scores.sort(function(a, b){ return b.score - a.score }); let elements = []; … I did all the later days at 1pm local time, including discreetly doing day 22 from my phone, SSHed into a tmux session on an MIT server, while I was at a relative’s wedding (45th/24th). Cut whatever corners you need to get your code out faster. A slightly more useful, less obvious way to phrase this advice, which is also the best advice I’ve ever gotten in competitive programming, is to make it hard for yourself to write bugs. CS. local function onPlayerJoin(player) local leaderstats = Instance.new("Folder") end. The competition is fierce — every year, thousands of people compete to get on the leaderboard. If you need to get past such a sensor, you might be able to reach the correct weight by carrying items from the environment. I am a Family Friendly ROBLOX Content Creator that loves to have fun with viewers! Each puzzle has two parts, which use the same text input and are related; to solve a part, you submit the right output corresponding to the input on the website. Getting a star first is worth 100 points, second is 99, and so on down to 1 point at 100th place. When the new version of your code is ready, you can initialize it with the running copy’s intermediate state or best result to speed it up. Write hacks. For example, say you’re trying to count something in a loop, but you’re not quite sure if your count is off by 1 from what the puzzle is asking for. Welcome to my Channel! Accessing Your Leaderboard in Unity. GitHub Pages, and Write both parts of that conversion code in one sweep before going to work on the rest of the solution, so there’s no chance of you converting in one direction but not the other. This script will show a player’s gold using an IntValue, a placeholder for an integer. This is not to mention the instances when concepts repeat and evolve between days. ), macros (q and @), and block visual mode (Ctrl-V) particularly useful for this kind of thing, but most popular code editors have facilities that can achieve similar effects. » Leaderboard code #1 March 25, 2016 15:00:55. amro3 Scratcher 2 posts Leaderboard code. HackerEarth is a global hub of 5M+ developers. More generally, learn to recognize the places you often write bugs, and stay alert or slow down when writing them. It is guaranteed that the player was added to the leaderboard before calling this function. Insert a script in it saying: Sometimes a problem will allow you to make some correct, simplifying assumptions when first coding a solution, but the problem will invalidate those assumptions in part 2 or in a later day, which you can’t see until later. If a problem gives you indices for a one-indexed list or array, it’s often less bug-prone to create a list or array that’s one bigger than what you need and just not use index 0 of it, than to remember to subtract 1 every time you use a problem-provided index. Firstly, this implies that if you want to be able to quickly assess whether your algorithm is fast enough, you’ll have to analyze your input yourself. What a difference a tab makes!4 Getting on the leaderboard is affected as much by programming skill as it is by the tiniest of mistakes and mental lapses, the kind that everybody makes. The event has a fantastic community surrounding it. 2019 Day 17 Part 2 (solution thread) is another example. But more on that shortly.↩, If this pothole is confusing, the phrase is from the abandoned draft, which probably makes the concept a bit more explicit.↩, Internet Problem Solving Contest also does this and takes the specific-input-file thing even further. On my first try on the very first part of AoC 2019, I was trying to write this code: This was enough to prevent me from getting on the part 1 leaderboard. 2019 Day 16 Part 2 was a somewhat infamous case of this, where the size of the first seven digits of people’s input signals made the problem much easier (extended reddit discussion).
