[1.18.1] How to add Structure ?

[zlappedx3]

Hello normally in 1.17.1 i call BiomeLoadingEvent for add some Structure from BiomeGenerationSettingsBuilder#getStructures() but when i modding on 1.18.1 getStructures() method is missing.

Don't ask me what I want, you should know what I want.

you need to add your custom Structures to the StructureSettings.configuredStructures in FMLCommonSetupEvent,
this requires an AT or you need to use Reflection, since it's a ImmutableMap and you need to replace the Map with a new ImmutableMap.

Note: you need to copy the old Map into the new Map, if you don't do that, the vanilla structures won't be generated

If StructureSettings#configuredStructures is private variable how to add to the StructureSettings#configuredStructures ?

mixin/core modding is not supported on this Forum, there are some use cases where you need mixin.
but this case is possible without mixin, so you don't ge support.
if you have a other use case for that you can ask on the Forge discord in the non-api-modding chanel, but only if this a true case
