Spawning Multiple Biomes in Custom Dimension (NullPointer Error)

[headchopperz]

Hi, ive spent the past two days trying to get multiple biomes to work on a custom dimension, and i think im pretty much there but i keep getting these NullPointer Errors when the code runs "this.provider.worldChunkMgr.cleanupCache();", in Wordserver.java.

 

Sorry if its a bit much to read, but i really need help wit this, im stumped.

 

Thanks.

 

INIT Code:

 

public static int DimID = 2;

...

DimensionManager.registerProviderType(DimID, Pokemob_WorldProvider.class, false);

DimensionManager.registerDimension(DimID, DimID);

 

Here are my files:

 

Pokemob_ChunkProvider.java

The full error log would be helpful. As it is, I can tell you that either this.provider or this.provider.worldChunkMgr is null.

[headchopperz]

Sorry for delay, i had a long sleep ^^.

 

I am on 1.5.2 using version 7.8.0.716 of forge (end of last month i think)

 

The error is when im creating a new world, i get to the main menu fine, the console log looks like this:

The code its referencing too is:

 

MinecraftServer.java, line 639:

[spoiler]                try
                {
                    worldserver.tick();
                }
                catch (Throwable throwable)

                    crashreport = CrashReport.makeCrashReport(throwable, "Exception ticking world");
                    worldserver.addWorldInfoToCrashReport(crashreport);
                    throw new ReportedException(crashreport);
                }[/spoiler]

 

If i comment out the try - catch to see more information about the error, i get this message instead:

Which points to this code: this.provider.worldChunkMgr.cleanupCache();

in WorldServer.java

 

Using the debugger i can tell you that.

 

this.provider = (mods.pokemob.common.World.Pokemob_WorldProvider) mods.pokemob.common.World.Pokemob_WorldProvider@ 7f0e8369

 

and this.provider.worldChunkMgr = (mods.pokemob.common.World.Pokemob_WorldChunkManager) mods.pokemob.common.World.Pokemob_WorldChunkManager@7a941409

 

If you want to know more information from the debugger just tell me

...Colour me obsequious. An NPE where neither of the variables are null?

[CowedOffACliff]

this.provider.worldChunkMgr.cleanUpCache() calls this.biomeCache.cleanupCache() which is your BiomeCache subclass. Make sure the this.biomeCache is actually being initialized correctly, and then go look at the cleanupCache() method in the BiomeCache base class since I don't see an implementation of it in your file. Assuming the crash is actually being caused in this chain somewhere continue to trace from BiomeCache.cleanupCache().
