[SOLVED] New dimension not generating top blocks and filler blocks


Recommended Posts

Posted

I created a new dimension with a custom ChunkProvider, WorldProvider and biome. The top and filler blocks for the biome don't generate whenever I change the ChunkProvider to use my mod block instead of stone.

The code for the entire mod can be found here:

https://github.com/ybilta/Deep-Freeze

 

Edit for clarification:

The problem occurs when use find/replace to change all instances of Block.stone in the custom ChunkProvider to ModBlocks.packedIce.

It would help me for one if you posted the snippet where you are replacing Block.stone with your own block; I couldn't find an instance of packed ice in your world generation files. What could be your problem, just a guess that you probably already considered, is that you are implementing your block wrong. You may need to call yourmod.packedIce instead of Block.packedIce. Just some ideas for you!

Here is the ChunkProvider file when Block.stone was replaced by ModBlocks.packedIce

I don't know much about biome generation, but I would see if stone can be replaced with a vanilla item easily, to see whether the problem is replacing stone or using your block to do it. Sorry I can't help more!

Just tested with that change. No luck. In any case, the forge documentation says that blocks are registered in preInit, was there a change not reflected there?

Narrowed down the error. When I have the ChunkProvider set to use Block.stone, the variable abyte in method provideChunk gets set correctly by the method generateTerrain. But when I have ChunkProvider use my modded block, aByte gets a lot of weird numbers, like -93. Could this be due to casting the id of my block to a byte? I kept the blocks id at 163 to prevent errors. But could this be happening anyways?

Fixed it! The issue lied in the replaceBlocksForBiome method of the ChunkProvider. There is a line in there that compares the byte b3 to the id of the block, without casting the id to a byte. This is an issue when your blocks id is between 128 and 255, because byte only goes up to 127. This didn't cause an issue with vanilla blocks I tested because their id is below 128. The fix was adding the cast to the block id. Below is the fixed method, I put comments around the fixed line.
