UPM: How to make a custom package

UPM: How to make a custom package So, Unity has this shiny new package manager, and you have code you want to share between projects - wouldn't it be great if we could bundle up our shared code and plug it into all the projects that need it? Let's figure out how to make our own Package!


Todo

  • Modify the project manifest
  • Make a package manifest
  • Package the manifest up with some test code
  • Try it out in Unity!
