How i can put my structures in to FlatGenerationSettings.STRUCTURES. The structures  var is final so i cant put mine like that

FlatGenerationSettings.STRUCTURES.put(MyStructure.RUN_DOWN_HOUSE.get(), CONFIGURED_RUN_DOWN_HOUSE);

The object itself is immutable, the data can be mutable. The issue is that the field accessor is private. ObfuscationReflectionHelper#getPrivateValue can be used to obtain the Map to which you can put the value during common setup.

But where i can get the instance
 

Map<Structure<?>, StructureFeature<?, ?>> STR = ObfuscationReflectionHelper.getPrivateValue(FlatGenerationSettings.class,instance,"STRUCTURES");

How familiar are you with Java and reflection? Also, read the javadocs on the method, do not supply a mapped name and instead the associated srg name (which can be obtained from forge-bot via '!mcpf <mapped_name>).

Apologies, you have to be on the forge discord to access the bot for the commands.

 

Now, if you wouldn't mind answering my question about your knowledge in Java and reflection.

I am a bigginer at Java and do not know much about reflection but I know it allows to get private var, methods, annotations and so

Yes, as you can see it has the obfuscated name which translate to its unique srg name and then finally the mapped name. You will need the srg name as your parameter.

The static keyword makes the field/method available at class level meaning you do not need an instance to grab the associated value. So, a null value can be passed in instead.
