I didnt want to come on to a forum to get help, but this is the only thing that is bugging me insanly.

 

Here is the error I get when I Create A New World

and here is the worldGen code:

 


public static void generateSurface(World world, Random rand, int posX, int posZ)
     {
       if ([---].generatePlatinumOre)
       {
         for (int i = 0; i < 8; i++) 
         {
           int randPosX = posX + rand.nextInt(16);
           int randPosY = rand.nextInt(30);
           int randPosZ = posZ + rand.nextInt(16);
           (new WorldGenMineableMeta([---].blockID, 0, 4)).generate(world, rand, randPosX, randPosY, randPosZ);
         }
       }
     }

 

 

Any help is very helpfull.

 

 

[---] means a file name, I will not show this for my own reasons :/

you don't need the if ([---].generatePlatinumOre) and the [---].blockID, 0,  might cause problems remove the 0 and that should work...

  • Author

the if statement is so that the generation of the ore is configurable, and the 0 is a custom from my WorldGenMineableMeta. Even when I remove them I still get an error

I betcha that [---] is 'mod_MedievalCraft2' But if its not, you shouldn't fucking care about stupid crap like that.

Not like anyone is gunna steal your TOTALLY unique ides.

 

Anyways, you have something that is null on line 60 or MeC2Core.java

Seems straight forward to debug and fix to me.

I do Forge for free, however the servers to run it arn't free, so anything is appreciated.

Thanks for the reply on the post, but it still wasnt that. Yes [---] is mod_MedievalCraft2 but I have consulted Alblaka about continueing his old mod before continueing.

 

There is no Null statement on which I can see, as you suggested. I have checked over the code to make sure of this. And any Nulls that shouldn't be there have been removed. It apppears on lin 74, which is the line which designates the block to generate, the meta value and the vein size, followed by the generate command. However, I am using WorldGenMineableMeta, and there are no nulls in there. If you would like to look at that to see if you can debug it. Feel free to ask, I will continue on weapons and machines untill the ore gen is working.

 

Cheers,

 

Jake

The string 'null' is not what a null pointer is... One of your objects. that you use on line 60 is null. Check your objects. Do some debugging.

Gotcha, without realising I put a null statement, I didnt even see it :/ Must of write it when I wasnt full aware.

 

Thanks anyway Lex, a question completely off topic. Does Forge support 128 textures and if yes, do I go about making a blahblahblah.png as normal, but all 128 x 128 and it will work?

 

If so, thats amazing.

 

If not, it should be in there :L

Forge supports HD textures, yes.

If Optifine is installed there are even more features, but those are icing at that point.
