Hi all,

 

I am working on my mod which adds a new dimension that generates just like the nether but with all custom blocks and such. Now that i had that all working i wanted to go with my custom WorldChunkManager called WorldChunkManagerMarona and start making it so that i can get more biomes to generate in my dimension. What i did:

- Made the following classes : (all classes from genlayer), WorldChunkManagerMarona, TheBiomeDeco (BiomeDecorator), BiomeGenBaseMarona, BiomeCacheBlock, BiomeCache, WorldTypeMarona, WorldTypeEventMarona.

Changed my chunkprovider and all my biomes so that tey use BiomeGenBaseMarona instead of BiomeGenBase.

 

I also have this custom Entity + model + renderer and i am not sure if that has anything to do with the Exception Ticking World cause when i look at the error where it points me to i see :

public void tick()
{       
//There is a lot more in this but i left it out
this.updateTimeLightAndEntities();
}

This is that method:

public void updateTimeLightAndEntities()
    {
        this.theProfiler.startSection("levels");
        int i;

        Integer[] ids = DimensionManager.getIDs(this.tickCounter % 200 == 0);
        for (int x = 0; x < ids.length; x++)
        {
            int id = ids[x];
            long j = System.nanoTime();

            if (id == 0 || this.getAllowNether())
            {
                WorldServer worldserver = DimensionManager.getWorld(id);
                this.theProfiler.startSection(worldserver.getWorldInfo().getWorldName());
                this.theProfiler.startSection("pools");
                worldserver.getWorldVec3Pool().clear();
                this.theProfiler.endSection();

                if (this.tickCounter % 20 == 0)
                {
                    this.theProfiler.startSection("timeSync");
                    this.serverConfigManager.sendPacketToAllPlayersInDimension(new Packet4UpdateTime(worldserver.getTotalWorldTime(), worldserver.getWorldTime()), worldserver.provider.dimensionId);
                    this.theProfiler.endSection();
                }

                this.theProfiler.startSection("tick");
                FMLCommonHandler.instance().onPreWorldTick(worldserver);
                CrashReport crashreport;

                try
                {
                    worldserver.tick(); 
                }
                catch (Throwable throwable) // This is where it throws the "Exception"
                {
                    crashreport = CrashReport.makeCrashReport(throwable, "Exception ticking world");
                    worldserver.addWorldInfoToCrashReport(crashreport);
                    throw new ReportedException(crashreport);
                }
//There is more below but as it doesn't even reach that far i didn't paste it in
           }
     }
}

If you want any looks inside any of these many classes please tell me which ones you need. I'll include my WorldChunkManager as it is mostly the "base class" of the dimension/biome thing.

I hope someone reads this who knows how to get the mutliple biomes in my dimension working.

I still get this error and now i have changed everything back to normal, didn't work..... So i don't know what to do next? anyone know what this error can be caused by?
