Usually, I would go around this problem, but right now I can't.

 

Whenever I make a class with more creative tab objects, their icon would always show up as blank. No matter how I register my blocks or whether I "pre-load" my class, it's always blank. The reason why is that the class with creative tabs loads way before my class with blocks and so my block objects end up being null. I have no idea what to do, and as usual, I expect it to be a simple solution as I tend to get stuck on retarded things... Here's the code:

public class BSMCreativeTabs
{
	public static void initialize() {BSMSlab.initialize();} // a way to "pre-load" my block class
	
	public static final CreativeTabs tabWoodRelated = new CreativeTabs("tabWoodRelated")
	{
		@Override
		@SideOnly(Side.CLIENT)
		public ItemStack getTabIconItem()
		{
			return new ItemStack(BSMBlocks.OAK_WOOD_ON_Y_AXIS, 1);
		}
		
		@Override
		@SideOnly(Side.CLIENT)
	    public void displayAllRelevantItems(NonNullList<ItemStack> list)
	    {
			int[][] blockIDs =
			{
				{26, 29, 32, 35, 137, 140, -1, -1, -1}, // WOOD 
				{12, 13, 14, 15,  16,  17, -1, -1, -1}, // PLANKS
				{37, 38, 39, 40, 142, 143, -1, -1, -1}  // LEAVES
			};
			getItemsFor(list, blockIDs);
	    }
		
	}.setNoScrollbar();
}     

package tt.betterslabsmod.main;

import java.util.HashMap;

import net.minecraft.block.*;
import net.minecraft.init.Blocks;
import tt.betterslabsmod.blocks.*;
import tt.betterslabsmod.blocks.BSMSlabBasic.BasicVariant;
import tt.betterslabsmod.options.BSMOptions;

public class BSMBlocks
{
/**
All blocks are loaded this way
**/
	public static final BSMSlab STONE;
	
	private static BSMSlab getRegisteredBlock(int ID)
	{
		return BSMSlab.BLOCK_REGISTRY.get(ID);
	}
	
	static
	{
		STONE = getRegisteredBlock(0);
	}
}

 

You shouldn't use ID's...

Those IDs are used to reduce complexity of my code and improve its flexibility - I prefer it that way.

IDs have nothing to do with past Minecraft IDs and they are completely invisible to end-users and they can't change in any way unless I change them since they are only used for stuff that I created, not Forge. Anyway, the problem has been solved....
