随手写的一个子进程

主进程

import ClearTouchGroundCacheCode from '../utils/workers/clearTouchGroundCache.worker.js';  
const blob = new Blob([ClearTouchGroundCacheCode], { type: 'application/javascript' });this.clearTouchGroundCacheWorker = new Worker(URL.createObjectURL(blob));this.clearTouchGroundCacheWorker.postMessage({type: 'clearCache',data: { cache: JSON.stringify(_context.touchGroundCache?.[2]), minGx, maxGx, minGz, maxGz, minX, maxX, minZ, maxZ },});// 接收 Worker 返回的数据this.clearTouchGroundCacheWorker.onmessage = (e) => {const msg = e.data;if (msg.type === 'clearDone') {const { keysToDelete, minX, maxX, minZ, maxZ } = msg.data;// 执行删除for (const key of keysToDelete) {if (_context.touchGroundCache[2]?.[key]) {// delete _context.touchGroundCache[2][key];_context.touchGroundCache[2][key] = null; //比delete更快}}console.log(`✅ 已清除x:${minX}-${maxX}z:${minZ}- ${maxZ}缓存`);}};
