说在前面

• 操作系统：windows11+wsl2
• physx版本：5.3.1
• 参考：physx-js-webidl (physx版本为该作者fork出的某个版本)

环境搭建

• 这里使用的是wsl2+docker进行编译的，搭建步骤参考：WSL2 上的 Docker 远程容器入门
• docker在wsl2下的安装使用有两种方式，即上述链接中使用的安装Docker Desktop以及在wsl2中直接安装docker的方式
• 建议使用安装Docker Desktop的方式
• docker compose安装

编译

• clone仓库

  git clone https://github.com/fabmax/physx-js-webidlcd physx-js-webidlgit submodule update --init
  

• 在wsl2中执行

  # Build the image
  docker compose up# Build Release
  docker compose run --rm builder ./make.sh
  

• 正常编译过程如下

  docker compose run --rm builder ./make.sh
  WARN[0000] /mnt/d/physx-js-webidl/docker-compose.yaml: `version` is obsolete

• 问题1：docker compose命令不存在
  安装docker-compose。(如果使用的是DockerDesktop，默认是有该命令的，docker compose)

• 问题2：.sh编码格式不正确

  -bash: ./make.sh: /bin/bash^M: bad interpreter: No such file or directory
  

  可以在vscode将其转换成LF
  

  

自定义接口

• 在本文中，添加了一个与createCollectionFromXml同级的接口，
  首先我们需要实现该接口：
  
  而后在idl文件中添加对应描述，其路径为

  .\PhysX\physx\source\webidlbindings\src\wasm\PhysXWasm.idl
  

  
• 最后重新编译即可，在生成的physx-js-webidl.js可以看到新增的接口
