Help with Registering a Foliage Placer Type

[ReikanFurrow]

I've been trying to make my own custom foliage shapes for a palm tree, but I can't seem to figure out a way to register my own foliageplacertypes. Any insight would be appreciated.

I apologize in advance if the answer is obvious, I am somewhat new to Java and am using this mod as a vehicle to learn.

Edit: some information that might be important: I am trying to create a palm tree with my own custom foliage shape for it. In the Tree Configured Feature, it calls for a FoliagePlacer, and I'd like to create my own.

The constructor of FoliagerPlacerType is private, making it inaccessible to any code outside of FoliagerPlacerType.java.
There are 2 ways to get around this. Both are Fabric or Minecraft specific, so it's unsurprising you couldn't find them, search engines don't give great results for Minecraft modding.

Option 1 is creating a public Mixin invoker for the FoliagerPlacerType constructor.

Option 2 is using Fabric's access wideners to change the access modifier of the constructor.

This is fine as long as you have prior programming experience. Otherwise it's better to learn Java first, Minecraft modding is a difficult learning environment.

Thank you for the swift and well composed response. I will use option 2, as it seems to be the solution to a number of other problems I have been facing.
