Custom structure generation

[Minus]

Hi everyone!

I was making some world generation for structures lately and I'm facing some kind of issue right now.
I'd like to add structure generation like in normal minecraft (like mineshafts, woodland mansion, villages etc.), but my current approach isn't quite good.
I'm currently using normal worldgen that is beeing called after whole world is created. I'd like to create new structure and place it before trees, foliage, caves etc.
Is that even possible to do? I've been looking through vanilla code, but couldn't find there any solution.
Thanks for any information!

You can set the priority to highest for yourself so it will generate before all.

" you can prioritize events in forge. In @SubscribeEvent you can put priority = Priority.HIGHEST for example (look up event annotation)."

There are different events, you probably want the load event or the decorate event (if it gets called before vanilla decoration)
