AlienWar

Game ini berlangsung di sebuah planet yang sangat ramai di mana alien adalah ras yang unggul. Tugas Anda adalah menciptakan alien Anda sendiri dan mengalahkan yang lainnya.

Papan

Ini adalah papan 2 dimensi.
Panjang satu sisi papan adalah Math.ceil(sqrt(species * 100 * 2.5))= ~ 40% dari papan yang digunakan. Papan adalah sebuah planet, jadi jika Anda berjalan keluar dari peta di barat, Anda kembali ke timur. Jika Anda berjalan di utara, Anda akan menemukan diri Anda di selatan.

Kemampuan

Setiap spesies di planet ini memiliki kemampuan. Di sini mereka:

Nama         Benefit 
life HP = lifeLVL * 5 (berkurang dengan setiap hit yang Anda ambil, 0 = mati), base HP = 10
kekuatan Serangan Anda melakukan kerusakan int acak dalam kisaran [1 hingga strengthLVL]
defense Pilih int dalam range [0 hingga (50 / defenseLVL + 1)] secara acak , jika int == 0 lalu hindari serangan berikutnya
visi Memberi Anda visiLVL / 2 bidang di sekitar visi Anda
cleverness Mengaburkan (meningkatkan) setiap kemampuan secara acak dalam kisaran [0 hingga clevernessLVL / 2] saat mengirim ke alien lain

Permainan

• Akan ada 100 contoh dari setiap pengiriman.
• Setelah instancing, setiap alien dapat menetapkan 10 poin kemampuan secara total. Anda dapat mengatur titik yang berbeda untuk setiap instance.
• Jika Anda menetapkan lebih dari 10 poin, instance mati.
• Sebuah game terdiri dari 1000 putaran. Setiap putaran:
  • Setiap alien harus mengembalikan gerakan move(char[] fields). Ini termasuk Move.STAY.
  • Jika beberapa alien berada di lapangan, 2 akan dipilih secara acak:
    • Jika keduanya sepakat tentang perdamaian (mengembalikan salah wantToFight) mereka akan tinggal di tempat mereka, kalau tidak mereka akan bertarung.
    • Loop ini sampai hanya satu alien tetap di lapangan atau semua setuju pada perdamaian.

• Jika alien membunuh sesuatu, dia mendapatkan 1/5 dari masing-masing kemampuan musuhnya . Pemenang HP akan diisi ulang dengan 2 * musuhLifeLVL .

• Pemenang adalah orang dengan kemampuan terbanyak (jumlah kemampuan alien yang hidup).

Perkelahian

Kedua alien akan saling memukul "pada saat yang sama", ini berarti jika Anda membunuh alien lain, ia masih bisa memukul Anda satu kali.

Menghindar: Sebelum Anda terkena, permainan akan menghitung jika Anda dapat menghindari serangan dengan menggunakan rand.nextInt(50 / defenseLvl + 1) == 0. DefenseLvl tidak akan pernah lebih besar dari 50 saat menghitung skill menghindar Anda (karenanya kemungkinan menghindar maksimum adalah 50%).

Memukul: Jika Anda tidak menghindari serangan, Anda akan terkena dan HP Anda akan berkurang sebesar rand.nextInt(enemy.getStrengthLvl()) + 1.

Perkelahian berakhir ketika salah satu atau kedua alien yang terlibat mati. Pemenangnya, jika ada, mendapat hadiah.

Gamerules

• Level dasar untuk setiap kemampuan (tanpa memberikan poin kemampuan) adalah 1 (basis HP adalah 10).
• Nilai-nilai yang dikirim ketika diminta untuk bertarung adalah kehidupan (bukan HP!), Kekuatan, pertahanan, dan tingkat visi .
• Kepintaran TIDAK dikirim saat diminta bertarung.
• Semua angka mengambang akan DIUNDANG ke bilangan bulat terdekat saat menggunakan / mengirimnya, tetapi disimpan dan ditingkatkan sebagai float.
• Peluang menghindar maksimum adalah 50%. Kalau tidak, perkelahian mungkin tidak akan pernah berakhir.

Mangsa

Ada 5 spesies yang sudah ada di lapangan. Karena mereka adalah mangsa, mereka memilih untuk tidak bertarung ketika diminta.

Paus: lvl 10 masa inap tetap   
Sapi: kekuatan 10 lvl Gerakan acak
Turtle: lvl 10 pertahanan South west
Elang: lvl 10 visi Memeriksa bidang, mencoba menghindari bahaya      
Manusia: kecerdasan 10 lvl timur laut

Mereka akan diwakili dengan huruf pertama mereka (yaitu Wuntuk paus) di peta (Alien dengan A, bidang kosong dengan spasi putih ' ').

Aturan tambahan

• Refleksi tidak diizinkan.
• Berinteraksi (instancing dll.) Dengan alien lain dilarang.
• Menulis / Membaca sumber daya eksternal seperti file atau database juga dilarang.
• Hanya pengajuan Java (versi 1.8) yang diizinkan (Java agak mudah, dan Anda tidak harus menjadi ahli untuk game ini).
• Semua kiriman harus memperluas kelas alien dan akan ditempatkan dalam paket alien.
• Saya akan menerima alien terbaik pada 19 Juli. Semua alien yang dikirim pada pukul 12:00 UTC hari itu akan diuji.
• Maksimal 3 kiriman per pengguna karena sudah ada sangat banyak alien.

Contoh alien

package alien;

import planet.Move;

public class YourUniqueNameHere extends Alien {

    public void setAbilityPoints(float[] abilities) {
        abilities[0] = 2; //life
        abilities[1] = 2; //strength
        abilities[2] = 2; //defense
        abilities[3] = 2; //vision
        abilities[4] = 2; //cleverness
    }

    public Move move(char[][] fields) {
        //you are in the middle of the fields, say fields[getVisionFieldsCount()][getVisionFieldsCount()]
        return Move.STAY;
    }

    public boolean wantToFight(int[] enemyAbilities) {
        //same order of array as in setAbilityPoints, but without cleverness
        return true;
    }

}

PredicatClaw (rawr)

Alien kucing ini akan menelan Anda seluruhnya (oke mungkin dia akan mengunyah Anda sedikit lebih dulu) ... jika Anda tampak lemah berdasarkan algoritme prediksinya.

Berkembang biak Predicats yang memiliki cakar dan taring yang lebih sengit daripada rekannya.

Ini seorang manajer. Secara alami, kepintarannya adalah 0 dan ia selalu berusaha untuk pergi ke tempat yang tidak disinari matahari. Dan, tentu saja, dia hanya akan melawan yang lemah dan sangat baik dalam menghindari masalah:

KartografiLongVisionAlien

Alien ini adalah varian yang konsisten melakukan salah satu upaya saya untuk menghasilkan alien yang berpotensi menang.

Ini memiliki visi 5x5 awal yang digunakan untuk membangun peta internal daerah sekitarnya memberikannya kemampuan menghindar musuh yang unggul.

Dalam pengujian saya tentang 100 putaran, rata-rata, itu menyelinap di depan semua alien lainnya. (09/07/2014)

Pilih Pertempuran Anda

Alien ini melarikan diri dari alien lain, tetapi berlari menuju mangsa (selama itu tidak akan membawanya ke alien).

Saya menggunakan algoritma genetika untuk membantu saya memilih nilai awal. Hasilnya menunjukkan bahwa kita harus mengandalkan kekuatan dan kehidupan untuk melewati pertempuran awal. Visi berguna nantinya, tetapi kita bisa mengambilnya dari musuh yang kalah.

Kami hanya bertempur, kami pikir kami bisa menang dengan nyaman - kami memperkirakan berapa banyak gerakan yang diperlukan untuk membunuh alien kami, berapa banyak yang diperlukan untuk membunuh musuh kami, dan hanya bergabung dalam pertempuran jika kami "dua kali lebih keras" dari lawan kita.

Pencandu

Alien ini kecanduan sesuatu . Dia memulai perang pada perbaikan yang cukup buruk.

Sementara perbaikannya menjadi kuat ( fix > 3) dia senang untuk duduk dalam keadaan pingsan dan siap untuk apa pun.

Namun, begitu perbaikannya mulai hilang ( fix <= 3) dia mulai tersandung di sekitar tanpa arah yang jelas mencoba untuk mencari tahu apa yang terjadi. Jika diminta untuk bertarung, ia menjadi berhati-hati dan hanya bertarung jika ia berpikir ia bisa menang.

Setelah perbaikannya habis, menjadi pecandu dia, dia harus memulai kembali lingkaran setan.

public class Junkie extends Alien {
    private int fix = 10;

    public void setAbilityPoints(float[] abilities) {
        abilities[0] = 4; //life
        abilities[1] = 3; //strength
        abilities[2] = 3; //defense
    }

Pemburu

Saya juga agak mencuri gerakan elang, kecuali sekarang dia ingin pergi ke segala sesuatu selain alien lainnya. Berusaha memburu dan membudidayakan mangsa sebanyak mungkin, dan bertarung hanya ketika tampaknya memiliki peluang bagus untuk menang.

package alien;

import planet.Move;

public class Hunter extends Alien   {
    private final static byte LIFE=0, STR=1, DEF=2, VIS=3, CLV=4;

    public void setAbilityPoints(float[] abilities) {

        abilities[STR] = 9;
        abilities[DEF] = 0;
        abilities[VIS] = 1;
        abilities[CLV] = 0;
    }

    public Move move(char[][] fields)   {
        int vision = getVisionFieldsCount(); //count of fields / middle
        char me = fields[vision][vision]; //middle of fields
        int leastDanger = Integer.MAX_VALUE;
        Move bestMove = Move.STAY;
        for (Move move : Move.values()) {
            int danger = 0;
            for (int i = 1; i <= vision; i++) { //loop through fields in specific direction
                int fieldX = vision + (i * move.getXOffset());
                int fieldY = vision + (i * move.getYOffset());
                switch(fields[fieldX][fieldY])  {
                    case 'A': danger++;
                    case ' ': break;
                    default: danger--;
                }
            }
            if (danger < leastDanger) {
                bestMove = move;
                leastDanger = danger;
            }
        }
        return bestMove;
    }

    public boolean wantToFight(int[] enemyAbilities)    {
        return ((double)this.getCurrentHp() * this.getDefenseLvl()) / (double)enemyAbilities[STR] > (enemyAbilities[LIFE] * enemyAbilities[DEF]) / this.getStrengthLvl();
    }
}

Lebih dari 9000!

package alien;

import planet.Move;

public class Over9000 extends Alien {
    public void setAbilityPoints(float[] abilities) {
        abilities[0] = 10;
    }

    public Move move(char[][] fields) {
        return Move.WEST;
    }

    public boolean wantToFight(int[] enemyAbilities) {
        return enemyAbilities[1] <= 9000;
    }

    @Override
    public int getStrengthLvl() {
        return 9001; // It's over 9000!!!!!!111
    }
}

Ya, ini merupakan upaya curang yang terang-terangan, tetapi mencicit melalui aturan. Jika getter di planet.Speciefinal, celah ini akan ditutup.

Batu

Saya pikir itu hanya menyerang orang yang lemah dan "pintar".

Tidak bisa memikirkan nama lain, orang ini secara acak membagikan 10 poin untuk kemampuannya. Hampir bergerak seperti Okinawa Life (terima kasih atas usahamu) dan hanya ingin bertarung jika kekuatannya lebih besar dari kekuatan musuh.

Bender "Bending" Rodriguez

Saya cukup liberal dengan komentar kode. Anda dapat membacanya dalam konteks untuk melihat apa yang sedang terjadi, tetapi saya juga akan menambahkan beberapa cuplikan di bawah ini.

Ringkasan

Alien ini beroperasi dengan prinsip bahwa membunuh manusia yang kecil itu mudah dan menggembungkan kekuatan yang Anda rasakan, yang akan mengintimidasi alien lain agar menjauh.

Paus dan Rajawali juga bisa ditekuk. =)

Gerakan

Pindah ke barat atau selatan kecuali jika Anda menemukan sesuatu yang menarik untuk diserang:

• Untuk mangsa yang pergerakannya diketahui, kami menambahkan keinginan mereka ke kotak di mana mereka akan menjadi giliran berikutnya.
• Bagi mereka yang tidak, kami membagi keinginan mereka secara merata di antara kotak-kotak yang mereka dapat pindah ke belokan berikutnya.
  • Alien mendapat bonus negatif ke kotak yang ada karena kulit pisang.

Jika Anda tidak menemukan sesuatu yang menarik di dekat Anda, cari tahu apakah selatan, barat, atau barat daya adalah pilihan yang lebih menjanjikan.

Memilih satu atau dua arah yang berlaku mengurangi kemungkinan bahwa Bender yang diberikan akan menemukan rekan senegaranya, dan memilih penghitung arah ke mangsa utamanya akan membantunya membunuh semua manusia lebih cepat.

Saya mungkin bisa mengubah angka-angka dalam matriks keinginan dengan algoritma genetik James_pic untuk hasil yang lebih baik, tapi saya tidak tahu bagaimana melakukannya.

Agresivitas

Bender kebanyakan menargetkan mangsa, dan cukup konservatif dengan mangsanya wantToFight. Siapa pun di atas Kekuatan 4 dijauhi kecuali Anda berpikir Anda sedang berurusan dengan manusia yang pintar. Kemanusiaan yang cerdas ditunjukkan dengan memiliki lebih banyak Pertahanan dan Visi daripada yang dimiliki alien. Ini disesuaikan selama kejadian oleh statistik kemampuan Bender sendiri, untuk menjelaskan alien membunuh kura-kura dan elang.
