Can I debug the code breakpoint after packaging?

I want to break the code after packaging, whether it is the blueprint or the C + + part. What should I do?

For C++, you can attach a debugger (like Visual Studio or Xcode) to the packaged game process, which allows breakpoints and stepping through code.

For Blueprints, the built-in debugger only works in-editor or PIE, so breakpoints won’t hit in packaged builds. If you need to debug Blueprints after packaging, one approach is remote Blueprint debugging, which lets you:

  • Set remote breakpoints on Blueprint nodes

  • Step through execution and inspect stack variables

  • Modify local and temporary variables at runtime

  • Call UFunctions remotely

This works for packaged builds on Windows, Android, and iOS. Here’s a short demo showing it in action:
