不清楚
小游戏开发者工具远程调试BUG- 当前 Bug 的表现(图1) [图片] - 预期表现(图2) [图片] 在点击复选框时,比如点击图示背景音乐,想渲染大图里某一部分(复选框变成选中状态),但是在客户端里整个背景都变成了一片黑,并且反复渲染了很多复选框,甚至把vConsole也渲染进去了(调试状态下),见图1,在开发者工具里正常,见图2。此BUG必现,代码示例: import ImageLoader from './imageLoader' const { screenWidth, screenHeight, devicePixelRatio } = wx.getSystemInfoSync() const canvas = wx.createCanvas() const ctx = canvas.getContext('2d') const img = wx.createImage(); img.src = 'images/all.png'; export default class Main { constructor(){ let imgLoader = new ImageLoader(); imgLoader.loadFile(['images/bg.jpg','images/all.png'], ()=>{ let back=wx.createImage(); back.src='images/bg.jpg'; //背景 ctx.drawImage(back,0,0,back.width,back.height,0,0,screenWidth,screenHeight); //复选框 ctx.drawImage(img,459,287,13,13,100,100,13,13); wx.onTouchStart((e)=>{ //选中复选框 ctx.drawImage(img,614,287,13,13,100,100,13,13); }); }) } } export default class ImageLoader { load(){ if(this.queue.length){ let img = wx.createImage(); img.onload = ()=>{ this.load() } img.src = this.queue.shift(); }else{ this.callback() } } loadFile(_arrs, _callback){ this.queue = _arrs; this.callback = _callback; this.load() } } 补充: 之前已经有人也发现了同样的BUG。 https://developers.weixin.qq.com/blogdetail?action=get_post_info&lang=zh_CN&token=218968836&docid=0004cea4df82d82298a6195695b800
