[1.7.2] Custom dimension NullPointerException

Bektor · June 2, 2014

Hello.

I'm currently updating my mod to 1.7.2, but now I'm getting the following error every time if I create a new world or if I load a world:

---- Minecraft Crash Report ----

Anyone?

Hi

My guess: one of these is not initialised properly (is still null)

PFBiomeBase.magicalforest,

PFBiomeBase.mountains,

PFBiomeBase.pineForest,

PFBiomeBase.primevalforest,

PFBiomeBase.silverwood

If that doesn't work, you could try setting your debugger to break on NullPointerException, and see which object is causing the problem. That will give you a clue on where to look next.

Ok, I checked if some ot the biomes is not initialised and all biomes are initialised.

The Debug thing returns this line in the Minecraft ClassLoader class:

final Class<?> clazz = defineClass(transformedName, transformedClass, 0, transformedClass.length, codeSource);

Yes, Forge triggers several Null Pointer Exceptions during startup. Just keeping resuming until it stops with a NullPointerException on your code PFGenLayerBiomes.java:41. Then look to see which variable is null.

Ok, it tested it and with every of my biomes it crashs the game and I tested biome for biome and didn't test if it will work with "Mojang biomes".

}

Oh and I post here only one biome class, because the other biome classes are exact the same, because I copied and renamed them only for testing if the code works.

The biome ids are 200, 201, 202, 203, 204.

I hope that this helps.

Hi

Did you try this?

Yes, Forge triggers several Null Pointer Exceptions during startup. Just keeping resuming until it stops with a NullPointerException on your code PFGenLayerBiomes.java:41. Then look to see which variable is null.

Which variable on that line was null?

Are you sure your PFBiomeBase.init() is called? You seem to have some strange recursive initialisation thing happening where the constructor of PFBiomeBase creates a number of other PFBiomeBase objects. As a general rule that is asking for trouble.

Yes, I'm sure that PFBiomeBase.init() is called, if not then my mod in 1.6 won't work too, but there everything works.

Well, but I'm on some part confused. The WorldChunkManager says the Biome isn't null and the Main-Class says the biome is null.

And then there is an error that says if I change the order what should be loaded first that there is a packet handling problem a few lines over it the nullpointerexception.

Anyone who knows how to fix this?

Abastro · June 5, 2014

Did you see that:

PFBiomeBase.magicalforest,

PFBiomeBase.mountains,

PFBiomeBase.pineForest,

PFBiomeBase.primevalforest,

PFBiomeBase.silverwood

is whether null or not when the getInts function called?

Bektor · June 5, 2014

Yes

        
PFBiomeBase.magicalforest,
       PFBiomeBase.mountains,
        PFBiomeBase.pineForest,
        PFBiomeBase.primevalforest,
        PFBiomeBase.silverwood

its null when the getInts() function is called, but I'm don't know how to fix it (if I load the Biome class in my main class I need to set an biome ID and to put every biome in the main class is not that what I want, only if there is no other way)

Abastro · June 5, 2014

I think you should call the PFBiome.init() method in the main class, not in the constructor of the biome.

It seems that the method is not called when the PFGenLayerBiomes is initialized.

* Be careful when you just uses static reference of a class. it might be null, especially when its methods are till not called.

Instead, static method would be better.

In line 70 of PrimevalForest.class the PFBiomeBase.init() will be called and its crashs with

public static void init()
public void init()

Abastro · June 5, 2014

I think your static init() method is colliding with the another init() which is not static..

Try change the name of the method.

Bektor · June 5, 2014

Well, you didn't understand what I mean. It crashs if the method init() is static and if its not static. (There is only one method called init())

Abastro · June 6, 2014

Then please show your current code.

Bektor · June 6, 2014

Then please show your current code.

Ok. Oh and a small notice to it, now it worked, because I moved the biomes in the main class, that I can work on other parts of this mod, but well, thats not so nice.

Here it is:

I hope that this code will you to find out how I can fix it, so that I can move the biomes back into the PFBiomeBase class.

Ok. Oh and a small notice to it, now it worked, because I moved the biomes in the main class, that I can work on other parts of this mod, but well, thats not so nice.

Here it is:

I would say - it looks fine. If it works, leave it like that.

I think it works because the order of object creation is now correct, i.e. the BiomeGenBase are initialised before you use them. If you really want to move them, you need to make sure that they are not null when you use them. You could consider an initialisation-on-first-use method if you're having trouble, i.e. check if it is null (never used before) and if so, initialise them.

But honestly, unless you're making a complicated mod I wouldn't bother.

I think this problem is related with the PFBiomeBase.init() is called after the PFGenLayerBiomes is constructed.

Where is the "new PFGenLayerBiomes()"?

and where was the init() method and how did you call it?

Bektor · June 8, 2014

I called the init() method over the constructor of the PFBiomeBase.class and this class is first called in postInit() [but there only the method inside the PFBiomeBase.class that checks for ID-conflicts].

Later its called in WorldChunkMangerPrimevalForest.class, but there only one biome and not the class itself (only the PFBiomeBase.primevalforest). Oh and I only checked if its called in any world classes and if its called in the main class, because I didn't think that its called in any other class, because the rest is mostly Entity, Items, Blocks...

And the PFGenLayerBiomes.class is called inside the abstract class PFGenLayer in this method: GenLayer[] makeTheWorld

[GenLayer biomes = new PFGenLayerBiomes(1L);]

Well I checked this out in the 1.6 version of my mod, because in which directiony and where the classes will be loaded, there is no difference between 1.6 and 1.7 of my mod and in the class PFGenLayerBiomes and PFGenLayer is no difference between that versions too.

Then where the PFGenLayerBiomes.makeTheWorld() is called?

The overall code about that part would be needed i think.
