.cconb 文件找不到

解决思路

先写一个程序遍历修改 web-mobile目录下所有的.cconb格式为.bin

# 转换cconb格式 to bin
def ConvertConb2bin(dir):for root, dirs, files in os.walk(dir):path = root.replace('\\', '/')for f in files:url = '%s/%s' % (path, f)info = os.path.splitext(f)name = info[0]ext = info[1]if ext == ".cconb":os.rename(f"{root}/{f}", f"{root}/{name}.cconb.bin")print(f"{root}/{name}.cconb.bin")

然后新建一条资源管线来处理 .cconb文件的加载

  //新加一个额外处理cconb的资源管道function append_cconb_convert_pip() {const assetManager = cc.assetManager;//新建一个额外处理cconb的资源管道assetManager.transformPipeline.append(function (task) {const input = task.output = task.input;for (let item of input) {if (!item.url) continue;//更改资源依赖item.url.endsWith(".cconb") && ( item.url = cc.path.changeExtname(item.url, ".cconb.bin") );}});//重写bin资源加载处理assetManager.downloader.register("bin", (url, options, onComplete) => {url.endsWith(".cconb.bin") ? assetManager.downloader._downloaders[".cconb"]() : assetManager.downloader._downloaders[".bin"]();})}

最后将管线写入到项目中

# 注入脚本到项目中
def intoApplication(dir):content = IUtils.fromFile(f"{dir}/application.js")content = content.replace("function topLevelImport(url) {", "%s\n\tfunction topLevelImport(url) {" % cconbPip, 1)content = content.replace("return loadAssetBundle(settings.hasResourcesBundle, settings.hasStartSceneBundle);","append_cconb_convert_pip();//创建cconb管道\n\treturn loadAssetBundle(settings.hasResourcesBundle, settings.hasStartSceneBundle);", 1)IUtils.writeInFile(f"{dir}/application.js",content)

完整的python源码：

from distutils.log import error
import os
import IUtils# cconbPip管线
cconbPip = '''//新加一个额外处理cconb的资源管道function append_cconb_convert_pip() {const assetManager = cc.assetManager;//新建一个额外处理cconb的资源管道assetManager.transformPipeline.append(function (task) {const input = task.output = task.input;for (let item of input) {if (!item.url) continue;//更改资源依赖item.url.endsWith(".cconb") && ( item.url = cc.path.changeExtname(item.url, ".cconb.bin") );}});//重写bin资源加载处理assetManager.downloader.register("bin", (url, options, onComplete) => {url.endsWith(".cconb.bin") ? assetManager.downloader._downloaders[".cconb"]() : assetManager.downloader._downloaders[".bin"]();})}

if __name__ == "__main__":web_mobileUrl = "./src/web-mobile"if not os.path.exists(web_mobileUrl):error("请将cocos打包后的 web-mobile文件夹 放入 src目录下")else:ConvertConb2bin(f"{web_mobileUrl}/assets")intoApplication(web_mobileUrl)

已及直接可调用的 EXE文件
点击下载

使用方法
将 web-mobile 放入解决后的 src目录下。点击运行 main.exe 即可
