UPDATE: isSuicidal () telah ditambahkan ke kelas pesawat, ini memungkinkan Anda untuk memeriksa apakah sebuah pesawat berada di jalur tabrakan yang tidak dapat diubah dengan dinding !!

UPDATE: updateCoolDown () dipisahkan dari simulateMove ()

PEMBARUAN: pembungkus entri non-Jawa, ditulis oleh Sparr , tersedia untuk pengujian, lihat komentar

UPDATE Zove Games Telah menulis visualisator 3D yang mengagumkan untuk KOTH ini, berikut adalah video youtube buruk dari PredictAndAVoid yang memerangi PredictAndAVoid.

Fungsi simulateMove () dari kelas Plane sedikit dimodifikasi sehingga tidak memperbarui pendinginan lagi, gunakan fungsi updateCoolDown () baru untuk itu, setelah pemotretan. IsSuicidal () yang baru mengembalikan true jika sebuah pesawat pasti akan mati, menggunakannya untuk memangkas pergerakan musuh dan menghindari menabrak tembok. Untuk mendapatkan kode yang diperbarui, cukup ganti kelas Controller dan Plane dengan yang ada di repo github.

Deskripsi

Tujuan dari tantangan ini adalah untuk mengkodekan dua pesawat dogfighting yang akan berhadapan dengan dua pesawat oleh kontestan lain. Setiap belokan Anda bergerak satu ruang dan memiliki kesempatan untuk menembak. Itu dia, sesederhana itu.

Hampir saja...

Arena dan kemungkinan gerakan

Arena adalah 14x14x14 berdinding di ruang angkasa. pesawat dari kontestan 1 mulai di lokasi (0,5,0) dan (0,8,0) dan di kontestan 2 di (13,5,13) dan (13,8,13). Semua pesawat memulai dengan terbang secara horizontal menjauh dari dinding vertikal yang paling dekat dengannya.

Sekarang karena Anda menerbangkan pesawat dan bukan helikopter, Anda tidak bisa hanya mengubah arah sesuka hati atau bahkan berhenti bergerak, sehingga setiap pesawat memiliki arah dan akan memindahkan satu ubin ke arah itu setiap belokan.

Arah yang mungkin adalah: Utara (N), Selatan (S), Timur (E), Barat (W), Atas (U) dan Bawah (D) dan kombinasi logis dari keenam itu. Dimana sumbu NS berhubungan dengan sumbu x, WE ke y dan DU ke z. NW, SU dan NED muncul dalam pikiran sebagai contoh kemungkinan arah; UD adalah contoh bagus kombinasi yang tidak valid.

Anda tentu saja dapat mengubah arah pesawat Anda, tetapi ada batasannya, Anda hanya dapat mengubah arah Anda paling banyak 45 derajat. Untuk memvisualisasikan ini, ambil kubus rubik Anda (saya tahu Anda punya satu) dan bayangkan semua 26 kubus kecil luar adalah arah yang mungkin (satu arah huruf adalah wajah, dua arah huruf adalah tepi dan tiga arah huruf adalah sudut). Jika Anda menuju ke arah yang diwakili oleh kubus kecil, Anda dapat mengubah arah ke setiap kubus yang menyentuh milik Anda (menyentuh angka secara diagonal, tetapi hanya menyentuh secara kasat mata, yang tidak menyentuh kubus).

Setelah semua pesawat menunjukkan ke arah mana mereka ingin berubah, mereka melakukannya dan memindahkan satu ubin secara bersamaan.

Anda juga dapat memilih untuk bergerak ke arah yang valid tetapi tetap terbang ke arah yang Anda tuju, sebagai gantinya mengubah arah Anda ke arah yang Anda pindahkan. Ini analog dengan perbedaan antara mobil yang melaju di tikungan dan jalur ganti mobil.

Menembak dan sekarat

Anda dapat menembak paling banyak sekali per putaran dan ini harus diputuskan pada saat yang sama Anda memutuskan ke arah mana untuk terbang dan apakah Anda ingin menjaga pesawat Anda (dan dengan ekstensi, pistol Anda) menunjuk ke arah yang sama atau tidak. Peluru ditembak tepat setelah pesawat Anda bergerak. Ada pendinginan satu putaran setelah memotret, pada putaran ketiga, Anda baik untuk pergi lagi. Anda hanya bisa menembak ke arah yang Anda terbangi. Peluru itu instan dan terbang dalam garis lurus hingga menyentuh dinding atau pesawat.

Mempertimbangkan cara Anda dapat mengubah arah dan juga 'mengubah jalur', ini berarti bahwa Anda dapat mengancam sebuah kolom hingga 3x3 baris di depan Anda di samping beberapa garis tunggal diagonal.

Jika menabrak pesawat, pesawat ini mati dan segera menghilang dari papan (karena benar-benar meledak atau apa). Peluru hanya bisa mengenai satu pesawat paling banyak. Peluru ditembak secara bersamaan, sehingga dua pesawat bisa saling menembak. Dua peluru tidak bisa bertabrakan di udara (sedih, saya tahu).

Namun dua pesawat dapat bertabrakan (jika mereka berakhir di kubus yang sama dan BUKAN jika mereka saling bersilangan tanpa berakhir di pesawat yang sama), dan ini mengakibatkan kedua pesawat sekarat (dan benar-benar meledak). Anda juga dapat terbang ke dinding yang akan mengakibatkan pesawat dalam pertanyaan sekarat dan diletakkan di sudut untuk memikirkan tindakannya. Tabrakan ditangani sebelum menembak.

Komunikasi dengan pengontrol

Saya akan menerima entri dalam java dan juga bahasa lain. Jika entri Anda ada di java, Anda akan mendapatkan input melalui STDIN dan akan menampilkan melalui STDOUT.

Jika entri Anda di java, entri Anda harus memperluas kelas berikut:

package Planes;

//This is the base class players extend.
//It contains the arena size and 4 plane objects representing the planes in the arena.
public abstract class PlaneControl {

    // note that these planes are just for your information, modifying these doesn't affect the actual plane instances, 
    // which are kept by the controller
    protected Plane[] myPlanes = new Plane[2];
    protected Plane[] enemyPlanes = new Plane[2];
    protected int arenaSize;
    protected int roundsLeft;

    ...

    // Notifies you that a new fight is starting
    // FightsFought tells you how many fights will be fought.
    // the scores tell you how many fights each player has won.
    public void newFight(int fightsFought, int myScore, int enemyScore) {}

    // notifies you that you'll be fighting anew opponent.
    // Fights is the amount of fights that will be fought against this opponent
    public void newOpponent(int fights) {}

    // This will be called once every round, you must return an array of two moves.
    // The move at index 0 will be applied to your plane at index 0,
    // The move at index1 will be applied to your plane at index1.
    // Any further move will be ignored.
    // A missing or invalid move will be treated as flying forward without shooting.
    public abstract Move[] act();
}

Mesin virtual yang dibuat dari kelas itu akan bertahan sepanjang seluruh kompetisi, sehingga Anda dapat menyimpan data apa pun yang ingin Anda simpan dalam variabel. Baca komentar dalam kode untuk informasi lebih lanjut.

Saya juga memberi Anda kelas pembantu berikut:

package Planes;

//Objects of this class contain all relevant information about a plane
//as well as some helper functions.
public class Plane {

    public void updateCoolDown(boolean shot) {
        coolDown = (shot && canShoot())?Controller.COOLDOWN:Math.max(0, coolDown - 1);
    }

    public boolean isSuicidal() {}
}


// A helper class for working with directions. 
public class Direction {
    // The three main directions, -1 means the first letter is in the direction, 1 means the second is, 0 means neither is.
    private int NS, WE, DU;

}


public class Move {
    public Direction direction;
    public boolean changeDirection;
    public boolean shoot;

    public Move(Direction direction, boolean changeDirection, boolean shoot) {}
}

Anda dapat membuat instance dari kelas-kelas ini dan menggunakan salah satu fungsinya sebanyak yang Anda suka. Anda dapat menemukan kode lengkap untuk kelas pembantu ini di sini .

Berikut ini contoh tampilan entri Anda (Mudah-mudahan Anda akan melakukan lebih baik daripada yang saya lakukan, sebagian besar pertandingan dengan pesawat ini berakhir dengan mereka terbang ke dinding, meskipun upaya terbaik mereka untuk menghindari dinding.):

package Planes;

public class DumbPlanes extends PlaneControl {

    public DumbPlanes(int arenaSize, int rounds) {
        super(arenaSize, rounds);
    }

    @Override
    public Move[] act() {
        Move[] moves = new Move[2];
        for (int i=0; i<2; i++) {
            if (!myPlanes[i].isAlive()) {
                moves[i] = new Move(new Direction("N"), false, false); // If we're dead we just return something, it doesn't matter anyway.
                continue;
            }
            Direction[] possibleDirections = myPlanes[i].getPossibleDirections(); // Let's see where we can go.

            for (int j=0; j<possibleDirections.length*3; j++) {

                int random = (int) Math.floor((Math.random()*possibleDirections.length)); // We don't want to be predictable, so we pick a random direction out of the possible ones.

                if (myPlanes[i].getPosition().add(possibleDirections[random].getAsPoint3D()).isInArena(arenaSize)) { // We'll try not to fly directly into a wall.
                    moves[i] = new Move(possibleDirections[random], Math.random()>0.5, myPlanes[i].canShoot() && Math.random()>0.2);
                    continue; // I'm happy with this move for this plane.
                }

                // Uh oh.
                random = (int) Math.floor((Math.random()*possibleDirections.length));
                moves[i] = new Move(possibleDirections[random], Math.random()>0.5, myPlanes[i].canShoot() && Math.random()>0.2);
            }
        }

        return moves;
    }

    @Override
    public void newFight(int fightsFought, int myScore, int enemyScore) {
        // Using information is for schmucks.
    }

    @Override
    public void newOpponent(int fights) {
        // What did I just say about information?
    }
}

DumbPlanes akan bergabung dengan turnamen bersama dengan entri lainnya, jadi jika Anda berakhir terakhir, itu adalah kesalahan Anda sendiri karena tidak setidaknya melakukan lebih baik daripada DumbPlanes.

Batasan

Batasan yang disebutkan dalam wiki KOTH berlaku:

• Setiap upaya untuk mengutak-atik controller, runtime, atau kiriman lainnya akan didiskualifikasi. Semua pengiriman hanya dapat bekerja dengan input dan penyimpanan yang diberikan.
• Bot tidak boleh ditulis untuk mengalahkan atau mendukung bot lain yang spesifik. (Ini mungkin diinginkan dalam kasus yang jarang terjadi, tetapi jika ini bukan konsep inti dari tantangan, itu lebih baik disingkirkan.)
• Saya berhak untuk mendiskualifikasi pengiriman yang menggunakan terlalu banyak waktu atau memori untuk menjalankan uji coba dengan sumber daya yang masuk akal.
• Bot tidak boleh menerapkan strategi yang sama persis dengan yang sudah ada, sengaja atau tidak sengaja.

Menguji kiriman Anda

Unduh kode Pengendali dari sini . Tambahkan kiriman Anda sebagai Something.java. Ubah Controller.java untuk memasukkan entri untuk pesawat Anda dalam entri [] dan nama []. Kompilasi semuanya sebagai proyek Eclipse atau dengan javac -d . *.java, lalu jalankan Controller dengan java Planes/Controller. Log kontes akan berada di test.txt, dengan papan skor di akhir. Anda juga dapat menelepon matchUp()langsung dengan dua entri sebagai argumen untuk hanya menguji dua pesawat terhadap satu sama lain.

Memenangkan pertarungan

Pemenang pertarungan adalah orang yang memiliki pesawat terakhir yang terbang, jika setelah 100 putaran, masih ada lebih dari 1 tim yang tersisa, tim dengan pesawat terbanyak yang menang. Jika ini sama, itu seri.

Penilaian dan kompetisi

Turnamen resmi berikutnya akan berjalan ketika hadiah saat ini habis.

Setiap entri akan memperjuangkan setiap entri lainnya (setidaknya) 100 kali, pemenang setiap pertandingan adalah yang dengan kemenangan terbanyak dari 100 dan akan diberikan 2 poin. Dalam hal pengundian, kedua entri diberikan 1 poin.

Pemenang kompetisi adalah yang paling banyak poin. Dalam hal pengundian, pemenangnya adalah orang yang menang dalam pertandingan di antara entri yang diundi.

Tergantung pada jumlah entri, Jumlah perkelahian antar entri dapat meningkat secara signifikan, saya mungkin juga memilih 2-4 entri terbaik setelah turnamen pertama dan mengatur turnamen elit antara entri tersebut dengan lebih banyak pertarungan (dan mungkin lebih banyak putaran per pertarungan)

(pendahuluan) Papan Skor

Kami memiliki entri baru yang dengan kuat mengambil posisi kedua di turnamen menarik lainnya , sepertinya Crossfire sangat sulit untuk ditembak untuk semua orang kecuali untuk PredictAndAvoid. Perhatikan bahwa turnamen ini dijalankan dengan hanya 10 pertarungan antara setiap set pesawat dan karenanya tidak ada representasi yang sepenuhnya akurat tentang bagaimana keadaan.

Berikut adalah contoh output dari pembungkus non-Jawa:

NEW CONTEST 14 20 menunjukkan bahwa kontes baru akan dimulai, di arena 14x14x14, dan itu akan melibatkan 20 putaran per pertandingan.

NEW OPPONENT 10 menunjukkan bahwa Anda menghadapi lawan baru, dan bahwa Anda akan melawan lawan ini 10 kali

NEW FIGHT 5 3 2 menunjukkan bahwa pertarungan baru melawan lawan saat ini mulai, bahwa Anda telah bertarung lawan ini 5 kali sejauh ini, menang 3 dan kalah 2 perkelahian

ROUNDS LEFT 19 menunjukkan ada 19 putaran tersisa dalam pertarungan saat ini

NEW TURN menunjukkan bahwa Anda akan menerima data untuk keempat pesawat untuk ronde pertarungan ini

alive 13 8 13 N 0
alive 13 5 13 N 0
dead 0 0 0 N 0
alive 0 8 0 S 0

Keempat garis ini menunjukkan bahwa kedua pesawat Anda masih hidup, masing-masing pada koordinat [13,8,13] dan [13,5,13], keduanya menghadap ke Utara, keduanya dengan cooldown nol. Pesawat musuh pertama sudah mati, dan yang kedua masih hidup, pada [0,8,0] dan menghadap ke selatan dengan nol cooldown.

Pada titik ini program Anda harus menampilkan dua baris yang mirip dengan yang berikut:

NW 0 1
SU 1 0

Ini menunjukkan bahwa pesawat pertama Anda akan melakukan perjalanan ke NorthWest, tanpa berbalik dari posisinya saat ini, dan memotret jika mampu. Pesawat kedua Anda akan melakukan perjalanan SouthUp, berbalik menghadap SouthUp, bukan menembak.

Sekarang Anda ROUNDS LEFT 18diikuti oleh NEW TURNdll. Ini berlanjut sampai seseorang menang atau ronde habis, pada titik mana Anda mendapatkan NEW FIGHTgaris lain dengan jumlah dan skor pertarungan yang diperbarui, mungkin didahului oleh a NEW OPPONENT.

Baku tembak

Ide awal saya adalah untuk menembak pesawat musuh dengan kedua pesawat saya pada saat yang sama, tetapi saya tidak bisa menyelesaikannya ... Jadi di sini adalah pesawat yang mencoba untuk menjauh dari dinding dan keluar dari jangkauan tembak dari musuh. Pesawat tidak boleh bertabrakan atau menembak pesawat yang ramah.

Sunting: metode ini possibleHitsselalu mengembalikan 0, setelah memperbaikinya dan menambahkan beberapa perbaikan kecil, kinerjanya lebih baik dari sebelumnya.

/*
    PREDICT AND AVOID

    Rules of behavior:
    - Avoid hitting walls
    - Move, safely, to shoot at spaces our enemy might fly to
    - (contingent) Move to a safe space that aims closer to the enemy
    - Move to a safe space
    - Move, unsafely, to shoot at spaces our enemy might fly to
    - Move to any space (remember to avoid walls)

    Chooses randomly between equally prioritized moves

    contingent strategy is evaluated during early fights

Dogfight 3D Visualizer

Saya menulis visualisasi kecil dan cepat untuk tantangan ini. File kode dan jar ada di repo github saya: https://github.com/Hungary-Dude/DogfightVisualizer
Dibuat menggunakan libGDX ( http://libgdx.com ). Saat ini UI sangat buruk, saya melakukan ini dengan cepat.

Saya baru belajar cara menggunakan Git dan Gradle jadi tolong beri komentar jika saya melakukan kesalahan

Menjalankan dist/dogfight.bat atau dist/dogfight.shuntuk melihat DumbPlanes beraksi!

Untuk membangun dari sumber, Anda memerlukan Gradle ( http://gradle.org ) dan integrasi Gradle untuk IDE Anda, jika Anda memilikinya. Kemudian klon repo dan jalankangradlew desktop:run . Semoga Gradle akan mengimpor semua perpustakaan yang diperlukan. Kelas utamanya adalah zove.koth.dogfight.desktop.DesktopLauncher.

Berjalan tanpa mengimpor

Salin semua file kelas pesawat ke dist/. Kemudian, jalankan dist/desktop-1.0.jardengan perintah ini:

java -cp your-class-folder/;desktop-1.0.jar;Planes.jar zove.koth.dogfight.desktop.DesktopLauncher package.YourPlaneController1 package.YourPlaneController2 ...

Saya akan memperbarui karena sumber untuk pengontrol Planes diperbarui, tetapi untuk memperbarui diri Anda, Anda perlu menambahkan beberapa kode Planes.Controller . Lihat github readme untuk info tentang ini.

Berikut screenshotnya:

Jika Anda memiliki pertanyaan atau saran, tinggalkan komentar di bawah ini!

EmoFockeWulf

Dia kembali. Dia membuat dirinya kelaparan hingga 224 byte. Dia tidak tahu bagaimana akhirnya dia seperti ini.

package Planes;public class EmoFockeWulf extends PlaneControl{public EmoFockeWulf(int s, int r){super(s,r);}public Move[] act(){Move[] m=new Move[2];m[0]=new Move(myPlanes[0].getDirection(),false,false);m[1]=m[0];return m;}}

Weeeeeeeeeeee - 344 byte setelah menghapus spasi putih

Apakah loop mengagumkan dan hal-hal. Tidak dapat kehilangan jika Anda melakukan loop.

package Planes;
public class W extends PlaneControl{
    int i,c;
    int[] s={1,1,1,0,-1,-1,-1,0};
    public W(int a,int r){
        super(a,r);
    }
    public void newFight(int a,int b,int c){
        i=4;
    }
    public Move[] act(){
        Plane p=myPlanes[0];
        if(++i<6)
            c=p.getX()==0?1:-1;
        Move n=new Move(i<8?p.getDirection():new Direction(c*s[(i+2)%8],0,c*s[i%8]),0<1,i%2<1);
        Move[] m={n,n};
        return m;
    }
}

EDIT: ternyata ketika pesawat saya mulai sebagai tim 2, mereka langsung menabrak dinding. Saya pikir saya sudah memperbaikinya sekarang. Semoga.

Pindahkan-dan-Tembak pesawat

Menghindari dinding dengan mencari ketika itu dekat dengan dinding & berputar, menembak ketika itu bisa.

DangerZoner

Each turn:
    1) Make a list of all possible locations to move to, explicitly excluding suicidal positions that will collide with the walls, an ally, or an ally's bullet.
    2) Rate each possible location using heuristics that estimate the approximate danger in that zone, accounting for the following factors:
        -Proximity to walls. (Manoeuvring constrictions and risk of collision.)
        -Proximity to fronts of planes. (Risk of mid-air collisions.)
        -High distance from enemy planes. (Risk of enemies easily turning to shoot.)
        -Intersection with all enemy attack vectors. (Explicit safety on the next round.)
        -Proximity to enemy forward vectors. (Approximate probability of being targeted in upcoming rounds.)
    3) If certain respective thresholds are met in the possible moves' danger ratings, then do the following if possible:
        -Take a potshot at a random position that an enemy might move to next turn (but never shoot an ally).
        -Take a potshot at an extrapolated position that an enemy will likely move to next turn if they keep up their current rate of turn (but never shoot an ally).
        -Turn to pursue the closest enemy.
        -Move randomly to confound enemy predictive mechanisms. (Disabled since implementing explicit enemy attack vectors in danger zone calculation.)
    4) If none of those thresholds are met, then choose the move rated as least dangerous.
