Hey、小怪兽

• 之前看到有 python 版本的转换，我自己写了 js 版本的，可以将公主连结解包的 _CHARA_BASE.cysp.bytes 和 _BATTLE.cysp.bytes 文件合成为 .skel
• fileName就是人物编号，修改完人物编号，需要看一下路径对不对，f1_path，f2_path，f3_path

const fs = require("fs");
const path = require("path");

const fileName = "310000";

const b_num = Buffer.from(fileName, "hex");
const f_num = b_num.toString("utf8");

const f1_path = "./dist/ccysp/" + fileName + "_CHARA_BASE.cysp.bytes";
const f2_path = "./dist/bcysp/" + fileName + "_BATTLE.cysp.bytes";
const f3_path = "./dist/skel/" + fileName + ".skel";

// 读取基础文件
const b1 = fs.readFileSync(f1_path);
let i = 0;
while (i < b1.length) {
  if (b1[i] === 0x1c) {
    break;
  }
  i++;
}
const result = b1.slice(i);

// 读取增量文件
const b2 = fs.readFileSync(f2_path);
i = 0;
while (i < b2.length) {
  let j = 0;
  let flag = true;
  while (j < b_num.length) {
    if (b2[i + j] !== b_num[j]) {
      flag = false;
      break;
    }
    j++;
  }
  if (flag) {
    break;
  }
  i++;
}
const animationCount = Buffer.alloc(1);
animationCount.writeUInt8(0x50, 0);
const b2sub = b2.slice(i - 1);
const mergedResult = Buffer.concat([result, animationCount, b2sub]);

fs.writeFileSync(f3_path, mergedResult);
