[1.6.4]How can I remove chest and spawners from generation?

[TheAwesomeGem]

How can I make it so that chest and spawner doesn't generate when chunk loads?

[TheAwesomeGem]

How can you alter the vanilla WorldGeneration?

[Eternaldoom]

Use an event

Use an event

 

Really specific.

 

On Topic: Is this an efficient way of doing it? I can't find any other way yet.

 

public class CustomWorldGenerator implements IWorldGenerator {

    @Override
    public void generate(Random random, int chunkX, int chunkZ, World world, IChunkProvider chunkGenerator, IChunkProvider chunkProvider) {
        Chunk chunk = world.getChunkFromChunkCoords(chunkX, chunkZ);
        Map<ChunkPosition, TileEntity> chunktiles = chunk.chunkTileEntityMap;

        for(Map.Entry<ChunkPosition, TileEntity> map : chunktiles.entrySet()){
            if(map.getValue().blockType.equals(Block.chest)){
                TileEntity tileentity = map.getValue();
                chunk.chunkTileEntityMap.remove(tileentity);

                if(tileentity != null){
                    tileentity.invalidate();
                }
            }
        }
    }
}

Removing TileEntity has no effect. You should remove the block.

...or find the way to prevent generation.

[TheAwesomeGem]

How do I prevent them from spawning? and/or how do I remove a block?

[TheAwesomeGem]

I still can't find a way to prevent generation of a block when ChunkLoad. How do you override a vanilla minecraft class?

As mentioned, there are various events that are related to creating world, loading chunks, etc.

 

In my tips on blocks tutorial, I have an example where I use the PopulateChunkEvent to replace all blocks with different block.  You could use same code but just delete the block without replacing it.
