Hi.

When I create a new world to search for my custom village Minecraft instantly crashes. This is the crash report:

It says something about a missing ID mapping and to check the class MapGenStructureIO.

 

java.lang.RuntimeException: StructureStart "com.sirpigman.pigmanvillages.structure.MapGenPigmanVillage$Start" missing ID Mapping, Modder see MapGenStructureIO

 

So the question is, how can I add an ID mapping to my structure?

 

EDIT: Yes, I have checked the class and trying to do it like there, but I couldn't get that to work.

[TheEnderKiller]

It even tells you: "Modder see MapGenStructureIO". What is not to understand about that?

Yeah I did that and tried registring the structure like there, but it didn't work. Sorry for not being clear.

[TheEnderKiller]

I created this class:

 

package com.sirpigman.pigmanvillages.structure;

import net.minecraft.world.gen.structure.MapGenStructureIO;

public class StructureRegister extends MapGenStructureIO {

public void registerStructures()
{
	registerStructure(MapGenPigmanVillage.Start.class, "Pigman Village");
        StructurePVillagePieces.registerVillagePieces();
}

}

 

Which is how structures are registred in MapGenIO:

 

static
    {
        registerStructure(StructureMineshaftStart.class, "Mineshaft");
        registerStructure(MapGenVillage.Start.class, "Village");
        registerStructure(MapGenNetherBridge.Start.class, "Fortress");
        registerStructure(MapGenStronghold.Start.class, "Stronghold");
        registerStructure(MapGenScatteredFeature.Start.class, "Temple");
        StructureMineshaftPieces.registerStructurePieces();
        StructureVillagePieces.registerVillagePieces();
        StructureNetherBridgePieces.registerNetherFortressPieces();
        StructureStrongholdPieces.registerStrongholdPieces();
        ComponentScatteredFeaturePieces.registerScatteredFeaturePieces();
    }

Alright, thanks for the help I guess...

Could you (or someone else) atleast explain what's wrong with the class so I can learn and use it in possible future experiences?
