[1.12.2]WorldGenMinable only spawns blocks if the vein amount is 4 or greater

[ijuststartedmoddingplshelp]

I just started recently and have been learning a lot.

I have been trying to generate a block on grass for quite some time now. 

I managed to get it correctly generated however the block only generates if the vein is 4 or greater (the actually blocks in the world that are generated generate anything from 1 to 4). If i set it to 3 or lower nothing will be generated.

Any fix for this or any other methods i can use to generate a block in a chunk size of 1 or 2.

Here is code for the world gen

Spoiler

package world;

import java.util.Random;

import com.KOBKingobrine.FirstMod.init.ModBlocks;

import net.minecraft.block.state.IBlockState;
import net.minecraft.block.state.pattern.BlockMatcher;
import net.minecraft.init.Blocks;
import net.minecraft.util.math.BlockPos;
import net.minecraft.world.World;
import net.minecraft.world.chunk.IChunkProvider;
import net.minecraft.world.gen.IChunkGenerator;
import net.minecraft.world.gen.feature.WorldGenMinable;
import net.minecraft.world.gen.feature.WorldGenerator;
import net.minecraftforge.fml.common.IWorldGenerator;

public class WorldGeneratorBlocks implements IWorldGenerator {

    private WorldGenerator snakePit, j4block;

    public WorldGeneratorBlocks()
    {
        snakePit = new WorldGenMinable(ModBlocks.SNAKE_PIT.getDefaultState(),1,BlockMatcher.forBlock(Blocks.GRASS));  //This block will only generate if the number parameter in the middle is higher than 4
        
    }
    
    public void generate(Random random, int chunkX, int chunkZ, World world, IChunkGenerator chunkGenerator, IChunkProvider chunk)
    {
        switch(world.provider.getDimension())
        {
        case 0:
            runGenerator(snakePit,world,random,chunkX,chunkZ,100,50,100);
            
        }
    }
    private void runGenerator(WorldGenerator gen, World world, Random rand, int chunkX, int chunkZ, int chance, int minHeight, int maxHeight)
    {
        
        int deltaY = maxHeight - minHeight + 1;
        for(int i = 0; i<chance;i++)
        {
            int x = chunkX * 16 + rand.nextInt(16);
            int y = minHeight + rand.nextInt(deltaY);
            int z = chunkZ * 16 + rand.nextInt(16);
            
            gen.generate(world,rand,new BlockPos(x,y,z));
        }
    }
    
    

}
 

I dont get any crashes even if the value is lower than 4

 

Thank you for any help

How did you confirm this as true?
