So attacking the opponent seems a better tactic: Heroes can also be shielded, such that they won't be controlled or winded out by the opponent. [My Experience] CodinGame Spring Challenge 2022 (Zero to Legend) . It's a 10 day free bot programming competition with over 11.000 registered participants. Its a 10 day free bot programming competition with over 11.000 registered participants. It's so much simpler when you have the actual referee code. The challenge worked by leagues (namely Wood 2, Wood 1, Bronze, Silver, Gold and Legend) where you had to defeat a NPC Boss and a fixed amount of players to rank up. Join our next contest for free now! For farming, I use a Monte-Carlo algorithm to find the next two moves that will maximize the collected mana. Bot for the CodinGame 2022 Spring Challenge. Each sub-method is composed of three steps. The first step could collect all recently seen opponents near my base, compute the future positions of spiders near my base, store the date at which a spider will leave the map or reach my base center, and collect all my available defenders (not controlled at the current turn). Pretty much everyone coded a routine to wind away large packs of monsters going towards the base, either as a last resort or to prevent a group WIND in the following turns. The programming language was free of choice. I decided the submit the bot to the arena and it passed legend on Saturday, to my great amusement . The base visibility radius is 6000 space units, so an opponent could send spiders directly to the base center in one turn, without being seen. A tag already exists with the provided branch name. Source code for CodinGame's Spring Challenge 2022 event. Broadcasted live on Twitch -- Watch live at https://www.twitch.tv/johncm99 Solve games, code AI bots, learn from your peers, have fun. As always, I started with a short-sighted greedy heuristic algorithm I enjoy this organization as I find it easier to add considerations, tweak the goal assignment, or test new tactics to implement assigned goals. The Spring Challenge 2022 at CodinGame. www.codingame.com. cast a shield spell on spiders directed toward the enemy base, such that they are insensitive to wind and control for 12 turns. The weights didnt change much with the number of defenders, outside of self-shields and patrol routes. The rationale was it would be easier to assess the strength of the defense, push it to a nice level, then assess the strength of the attack part. organizing the code such that it remains readable and extensible. consider only immediate action, without planning many turns, score those actions, and pick the best action for any available hero). mycode.prepbytes.com. The Optimization section is a bit hard for me as heuristics related . There was however an overpowered mechanic: wind spells are stacked. TBC See more at their website To be updated. If I had enough mana, I also would CONTROl far away monsters that would at one point come in range of the base and divert them to either the center of the enemy base or my own wind cannon starting point. Having a code organization and a way to test a bot locally, it was time to design a better bot to reach the legend league. le-de-France is densely populated and . For reference, a spider moves 400 units each turn, so the wind spells are quite effective to expel spiders. The remaining issue was how to use the local arena to validate that a change improved the bot performance? defend, to handle spider threats while keeping an eye on what an attacker could do. (i.e. CodinGame Spring Challenge 2022. When the attack phase was triggered, they would move into a position close to the edge of the enemy base, controling every monster in their path. Spring Challenge 2022 Source code for CodinGame's Spring Challenge 2022 event. 4CodinGame/SpringChallenge2022 issues, can help you solve programming problems. My final ranking. From April 21 to May 2, 2022, there was a programming contest on CodinGame. Sticking to that plan helped me to remain sane and progress toward the legend league. Also, the given referee on GitHub is in java, and I have not practiced that language since my engineering school days, I neved used the referee locally. Fun fact, with a really borked attacker hero, I already met that objective. Contribute to Glagan/Spring-Challenge-2022 development by creating an account on GitHub.

Discover the latest news regarding the Covid-19 pandemic spreading in Paris and Ile-de-France. I tried to code an attacker, but I did not have enough free time to work on the contest anymore. When I first saw the game rules, my objective became to pass legend OR be in the top 100 , as I knew that contest would be hard for me: There was a high probability that I would rage-quit this contest. From April 21 to May 2, 2022, there was a programming contest on CodinGame. Its a great resource to learn about game programming and it would be cool to increase that Haxe demand. Currently its at only 5% for Haxe. Anybody interested in joining? codingame.com. This bot reached the gold league. To measure the strength of the bot, I compute its win rate against five other bots I wrote: I improved my defense code until the bot largely beats the DEFEND bot. CodinGame Coding Games and Programming Challenges to Code Better Since heroes move twice as fast as spiders, I did not compute interception trajectories to reach a spider. www.codingame.com. You signed in with another tab or window. It was a lot of fun and many memorable battles (and bugs) were had. If no spider is in range for the next two turns, I move the hero to a hardcoded position where it has an increased chance to spot spiders entering the map after being spawned or spiders that will soon target my base. Managing Game State. I finally figured out a way to structure a heuristic bot that works for me. It's a two-player game where each player controls three heroes. Solve games, code AI bots, learn from your . Learn more. I ranked 264th out of 7695 players, thus reaching the middle of the pack in the Legends League.

The 3 attackers version wasnt ever chosen by my code so it didnt see much use. *2. Two players controls a team of heroes. Now, spiders are almost always outside of my base, so I naturally farm wild-mana with the same algorithm. I ignored the FARM bot, as it was too much at an advantage with three heroes to farm wild mana and defend. A player whose base drops to 0 hit points obviously loses the game. When I first saw the game rules, . That meant that I could assign my idle hero to attack without weakening my defense. I failed to obtain something usable due to bugs in the referee, incomplete information, weird logic, and fatigue (or maybe just fatigue ). I lose a lot of matches to players that were more often outside of the base than me. After a while (or a certain amount of mana was reached), they would both go towards an edge of the enemy base and stand there. The 1 attacker version was intended to counter overaggressive bots and it would focus on controling the most monsters into the enemy base to get a quick win (it would also spam-control the lone defender (if any) away to let monsters do the job). Are you sure you want to create this branch? CodinGame Spring Challenge 2022 Events parallax (0xA3 Monad) April 21, 2022, 5:42pm #1 The yearly CodinGame Challenge started today. Once a player loses three lives, the game is over. Overall, I really loved trying to do a smart bot and not just hardcode a wind cannon but the tactic was SO effective that I had to weight it heavily and my bot would end up doing the same thing 95% of the time. The situation would be worse with fewer matches to measure a bot performance. Fortunately, going to the gold league was easy for this contest, even though I'm struggling with heuristic-friendly games. When a single wind spell is cast, spiders and opponents in the spell effect area are pushed away for 2200 space units. It's then nearly impossible for me to tune a condition, combine behaviors or add considerations to the evaluation. https://www.codingame.com/contests/spring-challenge-2022/ Community starter AIs are . The Clash of Code section isn't a big of a deal since I'm used to speed-solve easy problems in CodeForces. The two spiders are in the area of effect and are pushed 2200 units upward. The game mechanics are interesting. I mostly focused on search algorithms before that contest, so tuning and evaluating heuristics remained quite obscure to me. Those heroes can move around a large map to protect a base from spiders' attacks. Lastly, find the best way to implement the assigned goal for each hero. The attacker routine on the other hand had a lot of different parameters. If nothing happens, download Xcode and try again. The twist is that the heroes can only attack monsters (who regularly and symmetrically spawn from the edge of the map), not other heroes nor enemy base. We were beaten by the University of Wroclaw, who proved to be formidable opponents throughout the challenge. To do so, I sorted the list of visible spiders like so: I took the first three sorted spiders and assigned a hero to each of them. I was hoping to get more Haxe people to CodinGame. As in the previous contest, I made a conscient effort to sketch a plan of action to reach my goal. If a hero is not attacking a spider that will target my base, and there is a spider in range, send that spider with a control spell toward the opponent's base. However, I knew it would remain quite far for the gold boss to reach the legend league. since the bot behavior is unpredictable, the win rates would be random. codingcompetitions.withgoogle.com.

CodinGameSpring Challenge 2022AI18,2883 CodinGame L'objectif est de dvelopper un programme . I used Python, of course. guard, stay in the base because an attacker is spotted, and handle spider threats if any, handle attacker, when an attacker is about to mess my defense (e.g. crafting and combining conditions/scores, heavily depend on the testing capabilities. I decided to write first an efficient defensive bot, that uses only two heroes (the last one remains idle). On Legends there was no Boss and players where ranked with an ELO-like system. Before the challenge, I grinded CodinGame to get a good grasp of what to expect during the challenge. by casting a wind on a healthy spider toward my base), try to cancel the wind effect while throwing the attacker out of my base. I foresaw that I will likely spend days validating my simulation and won't have time to use it for a search algorithm, provided I find a way to use a search for this game.

Other improvements include calculating 2 turns in advance for a quick setup, moving into position when possible rather than spending 10 mana winding a monster to the right place, going back to farming mode when mana was scarce and an utility to self-shield given the defender(s) history of controling or winding me out. Speaking of rock paper scissors, I didnt expect the wind cannon strategy to be so dominant so I went for a more adaptative bot. First, collect data to consider for assigning goals to heroes. Bienvenue sur cette srie de live consacre au "Spring Challenge 2022", tournoi organis par http://codingame.com. assess locally if a change in the code improved the bot. There were a lot of refinements to this : some people played with 3 defenders, trying to disrupt the so-dubbed wind cannon setup while waiting for the lone defender to be overwhelmed by monsters. Instead, I ordered each hero to move at the current position of their assigned spider. I would define a number of attackers and defenders with some variables to remember the game state of previous turns (things like probable strategy of the enemy, how much defenders he has, how much he tries to CONTROL my heroes). A tag already exists with the provided branch name. The next two points, i.e. control spiders toward the enemy base to increase the defense difficulty, control defenders outside of the base to give a higher chance to spiders to reach the opponent's base. Here is the main method of the bot: Nothing fancy yet: that function helps me to separate the code for defenders and the attacker while estimating how much time I could allocate to each hero. I may need to investigate how to make a referee compatible with brutaltester myself. Without testing, I would add bugged behaviors to the bot, such that it would become impossible to check if a change improves the bot: But this is not only due to the sluggishness of submissions. Some others went for 3 attackers, spamming CONTROL on the defender while pushing monsters in a reckless abandon trying to win faster than the other guy. Next, I analyze this data to assign each hero one of the following goals: Finally, for each assigned goal I use the allowed time to find the best way to implement it. Let's focus on the defense function to illustrate this organization. I'm inefficient at heuristic-friendly games (I mean games where usual search algorithms are not overpowered), as I tend to lose myself in the task complexity. get closer to a spider such that the hero can hit it, for each hit point, the spider's health decreases, and the player's mana increases. The teams start out at opposite corners of the map, near their base. Submits took hours to complete, making testing ideas quite hard. Rank: Unknown Language: Typescript (transpiled to JS). Rankings. Do you Know if haxe will be officialy supported soon ? November 2022 Prime Time Coding Challenge - Competitive Programming. RTSMOBA*1. AI . There was a problem preparing your codespace, please try again. Hey fellow programmers! Whenever a spider is inside a player base, it will target that base. I continued to improve the defense code until the win rates against all mixed versions were above 20%, meaning my defense was good enough to face sustained attacks. 10 days Kick Start Round H . Rated. This led to very interesting strategies : some people shielded monsters in their own base to prevent them from being WINDed in and get enough time to kill them by attacking normally. Spring Challenge 2022. CodinGame is a challenge-based training platform for programmers where you can play with the hottest programming topics. I feel this is generally the case for heuristics-friendly games. Prove your skills, win prizes, practice coding with other coders, have fun. Ashamed by the bot replays in the legend league, I decided to spend some time on Sunday to fix the attacker. Doing so generates mana, which is used to cast spells. I will focus on producing better bots faster. However, wild mana collected by either the player or the opponent is unknown. The challenge worked by leagues (namely Wood 2, Wood 1, Bronze, Silver, Gold and Legend) where you had to defeat a NPC Boss and a fixed amount of players to rank up. They then each had a generic routine (one for defense, one for offense). If no monster was found, it would patrol the edge of the base, trying to farm mana without getting too far. CodinGame Spring Challenge 2022 CodinGame Spring Challenge 2022 AI7695(18288)199 . I would WIND out packs of monsters or enemy getting 1) too close to the base or 2) dangerously close to each other, as that was probably a setup for a wind cannon. README.md main.py README.md Codingame spring challenge 2022 A repy for my attempt on the spring challenge at codingame in 2022. They are multiple strategies to win and it's possible to switch from different strategies depending on the context (remaining life, attacker spotted, large mana amount, etc). Haxe is still not officially supported but there is a small extern that implements the CodinGame commands for the JavaScript, Python and Lua Targets. --- Join the CodinGame. TBC.

The le-de-France (/ i l d f r s /, French: [il d fs] (); literally "Isle of France") is the most populous of the eighteen regions of France.Centred on the capital Paris, it is located in the north-central part of the country and often called the Rgion parisienne (pronounced [ej paizjn]; English: Paris Region). They each get 1 base with 3 hit points (on opposed corners) and 3 heroes who can move, attack and use spells. If the spider reaches the central part of a base, the corresponding player loses one life. Online programming contest and hackathon " CodinGame Spring Challenge 2022". I will play with such organizations in other games to overcome my aversion to heuristic-friendly games . Here are the simplified rules of the game, named Spider Attack. In such a game, going deeper in the search tree is enough to pick the best action to lead to a sure victory. Instead, I thought to create multiple reference bots, using different strategies, and measure the performance of the tested version against all those bots. The principle was the same : for a given hero, get all of his possible actions, weight them against the game state and execute the best scoring course of action. send that spider to the opponent's base central point by casting a wind spell. Throughout the game monsters will appear regularly on the edges of the map. My slowness is less noticeable when I write search algorithms: craft conditions and scores with numbers, e.g., what are the criteria to decide an attacker is a threat to our defense and should be removed? A hero can prevent a spider from attacking a base with different actions: With three heroes in defense, it's very unlikely to lose a life.
