Bullet.cs (Pattern 1)

นิสิตหลายคนทำการคัดลอก Ball.cs มาเป็น Bullet.cs (47180278, 51180248, 5210404889, 5210404897, 5210400425, และ 5210405036) นี่ไม่นับเป็นการลอกเนื่องจากเป็นการใช้โค้ดเก่าของอาจารย์ อย่างไรก็ดีโค้ดของนิสิต 7 คนข้างล่างนี้มีลักษณะเด่นเหมือนๆ กัน ดังต่อไปนี้ คือ

  • เหลือเมธอด CollideOnTopSurface และ ColildeOnButtomSurface ไว้ ไม่คง CollideOnLeftSurface และ CollideOnRightSurface ของ Ball.cs เดิมไว้
  • กำหนดให้ Bullet มีขนาด 5 x 5 ช่องเหมือนๆ กัน

นอกจากนี้ไฟล์ของนิสิตบางคู่ัยังเหมือนกันทุกไบต์ จึงสันนิษฐานเอาไว้ว่าลอกกัน
