jmgomez / NimForUE

Nim plugin for UE5 with native performance, hot reloading and full interop that sits between C++ and Blueprints. This allows you to do common UE workflows like for example to extend any UE class in Nim and extending it again in Blueprint if you wish so without restarting the editor. The final aim is to be able to do in Nim what you can do in C++

genbindings hangs when adding NimForUE to existing project based off the source. #54

It's expected that you'll add NimForUE to a new project. And in that situation generating bindings for a new project with the source works.

I tried to add NimForUE to my GAS project and the genbindings task got stuck. Normally, the task completes in about a minute and a half on my system on a new project, but on the GAS project, I tried several times and had to kill the editor after 2 minutes.

Comparing the output of the completed and hung task looks identical at a glance. Completed:

Hung:

Based on the console output, and the generated data in src/.reflectiondat/ueproject.nim it looks like the commandlet completes but the process doesn't close for some reason.

What about when you run it through AActorCodegen does it complete?

geekrelief commented 2 months ago

Yeah, I did that after the first time it hung, just to move forward, and it did complete.

Going to close this. In my new project, I'm able to regen the bindings against the latest patch.
