My mod overrides vanilla villages in order to add many changes to them and for them to go in different biomes. With some assistance from the forum helpers I was able to override the vanilla villages by having a new village file with a new village structures and then overrding the original villages with setting a new gen on InitMapGenEvent. However, this prevents villages and village buildings from other mods from spawning which is a serious issue. How do I override village structures and VILLAGE_SPAWN_BIOMES without overriding village stuff from other mods. (BTW, I'm very very bad with reflecting)

 

The actual act of changing the village gen:

 

public class ChangeVillageGeneration {

	@SubscribeEvent
	public void changeVillageGen (InitMapGenEvent event) {
		if (event.getType() != null && event.getType() == EventType.VILLAGE){
			IvMapGenVillage newGen = new IvMapGenVillage();
			event.setNewGen(newGen);
		}
	}	
	
}

 

Current Reflector:

 

ublic class Reflector {
	
	public static Object reflectMethod1(List<VillageStructures.PieceWeight> list, Random random, int size){
		
		Class reflectClass = net.minecraftforge.fml.common.registry.VillagerRegistry.class;
		Method method;
		try {
			method = reflectClass.getMethod("addExtraVillageComponents", VillageStructures.PieceWeight.class, Random.class, int.class);
			Object returnValue = method.invoke(null, list, random, size);
			return returnValue;
		} catch (NoSuchMethodException e) {
			// TODO Auto-generated catch block
			//e.printStackTrace();
		} catch (SecurityException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IllegalAccessException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IllegalArgumentException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (InvocationTargetException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		return null;
      }
	public static Village reflectMethod2(VillageStructures.Start start, VillageStructures.PieceWeight weight, List<StructureComponent> structureComponents, Random rand, int structureMinX, int structureMinY, int structureMinZ, EnumFacing facing, int componentType){
		
		Class reflectClass = net.minecraftforge.fml.common.registry.VillagerRegistry.class;
		Method method;
		try {
			method = reflectClass.getMethod("getVillageComponent", List.class, VillageStructures.Start.class, VillageStructures.PieceWeight.class, StructureComponent.class, Random.class, int.class, EnumFacing.class);
			Object returnValue = method.invoke(null, weight, start , structureComponents, rand, structureMinX, structureMinY, structureMinZ, facing, componentType);
			Village returnObj = (Village) returnValue;
			return returnObj;
		} catch (NoSuchMethodException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (SecurityException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IllegalAccessException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IllegalArgumentException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (InvocationTargetException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		 {
			return null;
		}
      }

I think you are looking for net.minecraftforge.fml.common.registry.VillagerRegistry.addExtraVillageComponents in 

public static List<StructureVillagePieces.PieceWeight> getStructureVillageWeightedPieceList

What do you mean by that?

Well, I assume that your function :

VillageStructures.getStructureVillageWeightedPieceList(rand, size)

function doesn't have the line :

net.minecraftforge.fml.common.registry.VillagerRegistry.addExtraVillageComponents(list, random, size);

I think I do as reflectMethod2 is the method you are talking about:

 


    private static VillageStructures.Village findAndCreateComponentFactory(VillageStructures.Start start, VillageStructures.PieceWeight weight, List<StructureComponent> structureComponents, Random rand, int structureMinX, int structureMinY, int structureMinZ, EnumFacing facing, int componentType)

        if (oclass == VillageStructures.House4Garden.class)
        {
            structurevillagepieces$village = VillageStructures.House4Garden.createPiece(start, structureComponents, rand, structureMinX, structureMinY, structureMinZ, facing, componentType);
        }
        else if (oclass == VillageStructures.Church.class)

        }
        else if (oclass == VillageStructures.House1.class)

        {
            structurevillagepieces$village = VillageStructures.House3.createPiece(start, structureComponents, rand, structureMinX, structureMinY, structureMinZ, facing, componentType);

It may not work like that since I'm pretty bad with reflectors.

    • Version 1.19 - Forge 41.0.63 I want to create a wolf entity that I can ride, so far it seems to be working, but the problem is that when I get on the wolf, I can’t control it. I then discovered that the issue is that the server doesn’t detect that I’m riding the wolf, so I’m struggling with synchronization. However, it seems to not be working properly. As I understand it, the server receives the packet but doesn’t register it correctly. I’m a bit new to Java, and I’ll try to provide all the relevant code and prints *The comments and prints are translated by chatgpt since they were originally in Spanish* Thank you very much in advance No player is mounted, or the passenger is not a player.
