OneHourProcessing 七日目

一週間経った…だと…？
今日作ったのは「ライフゲーム」
内容はこんな感じ

作るのにかかった時間は「52分58秒」
久々の時間内…やったぜ

コード

Board board;

{
  size(800, 450);
  reset();
}

void draw()
{

  board.game();
}

void reset()
{

  board = new Board(80, 45);
  board.addPerturn(int(random(40)) + 20, int(random(15)) + 15, "RANDOM");
  board.addPerturn(int(random(40)) + 20, int(random(15)) + 15, "RANDOM");

    board.addPerturn(2, mouseY / (height / 45), "SPACESHIP");
  else
    reset();
