C-TURTLE 海龟状态海龟 0 步数 0 出生 0 DNA 控制速度 ⏮︎ ⏸︎ 1× ⌫ 循环 F L R B P C + - 使用方法：通过编写指令到海龟的DNA中移动海龟。 F：向前移动海龟 L：将海龟向左旋转45°（逆时针） R：将海龟向右旋转45°（顺时针） B：生一只小海龟 P：排便 C：清理便便海龟在DNA末尾死亡。小海龟从DNA的开头重新开始。我不太擅长艺术，所以海龟看起来像这样：■ 灵感来自Isabel Beach的L系统和海龟图形，以及Susam Pal的CFRS。源代码和示例在GitHub上。© 2025 Michael Erickson

      <h2>HOWTO</h2>
      <p>Move the turtle by writing instructions into its DNA.</p>
      <ul>
        <li><strong>F</strong>: move the turtle <strong>forward</strong></li>
        <li><strong>L</strong>: rotate the turtle 45° <strong>left</strong> (counter-clockwise)</li>
        <li><strong>R</strong>: rotate the turtle 45° <strong>right</strong> (clockwise)</li>
        <li><strong>B</strong>: make a <strong>baby</strong> turtle</li>
        <li><strong>P</strong>: <strong>poop</strong></li>
        <li><strong>C</strong>: <strong>clean</strong> up the poop</li>
      </ul>
      <p>The turtle dies at the end of the DNA.  Baby turtles start over at the beginning of the DNA.</p><p>I'm not much of an artist, so the turtles look like this: <strong>■</strong></p>
