Math.random override (사과게임)

javascript:window._s=0;document.getElementById("_s_input")||document.body.insertAdjacentHTML("afterbegin",'<span id="_s_box" style="position:fixed;top:8px;left:50%;transform:translateX(-50%);z-index:2147483647;background:#fff;padding:4px 8px;border:1px solid #888;border-radius:4px"><input type="number" id="_s_input" value="0" style="width:6em"><button onclick="window._s=+document.getElementById(\'_s_input\').value">RESET</button><button onclick="document.getElementById(\'_s_box\').remove()">HIDE</button></span>');Math.random=function(){_s|=0;_s=(_s+0x6D2B79F5)|0;let t=Math.imul(_s^(_s>>>15),1|_s);t=(t+Math.imul(t^(t>>>7),61|t))^t;return((t^(t>>>14))>>>0)/4294967296;};

사과 게임을 많이하다가, 지나간 게임이 아쉬워서 만들었다. 이러저러한 노력끝에 북마클릿으로 등록해 사용하면 좋을 것 같아서 압축적으로 표현해 봄.

javascript:
window._s = 0;

document.getElementById("_s_input") ||
document.body.insertAdjacentHTML(
  "afterbegin",
  '<span id="_s_box" style="position:fixed;top:8px;left:50%;transform:translateX(-50%);z-index:2147483647;background:#fff;padding:4px 8px;border:1px solid #888;border-radius:4px">' +
    '<input type="number" id="_s_input" value="0" style="width:6em">' +
    '<button onclick="window._s=+document.getElementById(\'_s_input\').value">RESET</button>' +
    '<button onclick="document.getElementById(\'_s_box\').remove()">HIDE</button>' +
  '</span>'
);

Math.random = function () {
  _s |= 0;
  _s = (_s + 0x6D2B79F5) | 0;
  let t = Math.imul(_s ^ (_s >>> 15), 1 | _s);
  t = (t + Math.imul(t ^ (t >>> 7), 61 | t)) ^ t;
  return ((t ^ (t >>> 14)) >>> 0) / 4294967296;
};

스타일링은 역시나 AI 써야 잘 나오는 것 같다. 랜덤함수도 Mulberry32라는 것을 추천받아 사용해 봄.
