In this tutorial, I'm going to teach you how to create a new creative tab, using forge, that you can add your own or vanilla blocks/items.

So first of all we need our main class which should look something like this:

package eb99;
import net.minecraft.src.Block;
import net.minecraft.src.CreativeTabs;
import net.minecraft.src.Material;
import cpw.mods.fml.common.Mod;
import cpw.mods.fml.common.event.FMLInitializationEvent;
import cpw.mods.fml.common.event.FMLPreInitializationEvent;
import cpw.mods.fml.common.network.NetworkMod;
import cpw.mods.fml.common.registry.GameRegistry;

@Mod(modid = "ModID", name = "modname", version = "version number")
@NetworkMod(clientSideRequired = true, serverSideRequired = false)
public class Tests {
public static CreativeTabs tab;
@cpw.mods.fml.common.Mod.Init
public void Init(FMLInitializationEvent event){
tab = new Tab(12, "Tab");
}
}

You can see that we have

public static CreativeTabs tab;

to define a new tab and then

tab = new Tab(12,"Tab")

which tells the game that its a new instance of the Tab Class which we will write later, gives it a tab position of 12 (At the start of page 2) and a unique ID of "Tab"

We are now going to write the Tab Code:

package eb99;
import cpw.mods.fml.common.Side;
import cpw.mods.fml.common.asm.SideOnly;
import net.minecraft.src.Block;
import net.minecraft.src.CreativeTabs;

public final class Tab extends CreativeTabs
{
	 public Tab(int par1, String par2Str)
	 {
			 super(par1, par2Str);
	 }
	 @SideOnly(Side.CLIENT)
	 public int getTabIconItemIndex()
	 {
			 return Block.glass.blockID
				
	 }

	 public String getTranslatedTabLabel()
	 {
		 return "Tests";
	 }
}

This Creates a new tab which extends CreativeTabs. We use the getTabIconFromIndex() method to determine what the tab uses as its icon. This can be a custom block or a vanilla block then we use the getTranslatedTabLabel() method to give the in-game name to that tab.
Now upon launching the game, in creative, you should have 2 arrows to go back and foward. If you were to navigate to the second page you should see your tab which is fully clickable.

In this tutorial, I'm going to show you how to set up a configuration system for blocks. First you need to have a basic block ( I'll add a tutorial if one is requested but there are plenty out there ) then you will need to remove the block ID from where you define the block i.e:

block = new Block(200,0,Material.rock);

and replace it with

block = new Block(newBlockID,0,Material.rock);

and you need a new int called newBlockID

public static int newBlockID;

Now to set the value of this ID we are going to use this bit of code:

@PreInit
public void preInit(FMLPreInitializationEvent event) {
config.load();
Configuration config = new Configuration(event.getSuggestedConfigurationFile());
newBlockID = config.getBlock("What It will say next to the ID in the config file goes here", 2000).getInt();
config.save();
}

We define a new property which later gets parsed as an int as the value of newBlockID, we give it a name in the file and a default ID of 2000
Now you have a config file which will generate in yourMCPWorkspace/jars/config/modname.cfg

Block metadata allows you to have up to 16 blocks under 1 ID which allows for greater compatibility and ID management. To start with you're going to require a block defined like this:

public static Block metadataTestBlock;

then in your'e initialization are i.e

@Init
public void Init(FMLInitializationEvent event) {
metadataTestBlock = new MetadataTestBlock(2000);
}

2000 is the ID that it will start at then followed by 2000:1, 2000:2 etc etc

Then, you will need to create a new class called MetadataTestBlock and put into it this code:

package net.minecraft.src;
import cpw.mods.fml.common.Side;
import cpw.mods.fml.common.asm.SideOnly;
import java.util.List;
import net.minecraft.src.Block;
import net.minecraft.src.CreativeTabs;
import net.minecraft.src.ItemStack;
import net.minecraft.src.Material;
public class MetadataTestBlock extends Block
{
public MetadataTestBlock(int ID)
{
super(ID, Material.rock);
setHardness(1F);
setResistance(3F);

}

@SideOnly(Side.CLIENT)
public String getTextureFile() {
return "Your Image File Here i.e /testmod/Block.png";
}
@SideOnly(Side.CLIENT)
public int getBlockTextureFromSideAndMetadata(int i, int l) {
switch (l) {
case 0:
	 return 0;
case 1: return 1;
case 2: return 2;
case 3: return 3;
case 4: return 4;
case 5: return 5;
case 6: return 6;
case 7: return 7;
case 8: return 8;
case 9: return 9; }
return 0;
}
public int damageDropped(int par1)
{
	 return par1;
}

public void getSubBlocks(int i, CreativeTabs tab, List list)
{
list.add(new ItemStack(i, 1, 0));
list.add(new ItemStack(i, 1, 1));
list.add(new ItemStack(i, 1, 2));
list.add(new ItemStack(i, 1, 3));
list.add(new ItemStack(i, 1, 4));
list.add(new ItemStack(i, 1, 5));
list.add(new ItemStack(i, 1, 6));
list.add(new ItemStack(i, 1, 7));
list.add(new ItemStack(i, 1, 8));
list.add(new ItemStack(i, 1, 9));
}
}

You MUST remember to change the image file in the getTextureFile() method.
Next you will need another class file called MetadataTestBlockItem and inside it place this code:

package TechCraft;
import net.minecraft.src.CreativeTabs;
import net.minecraft.src.ItemBlock;
import net.minecraft.src.ItemStack;
import cpw.mods.fml.common.Side;
import cpw.mods.fml.common.asm.SideOnly;
public class MetadataTestBlockItem extends ItemBlock
{
public MetadataTestBlockItem(int par1)
{
super(par1);
setMaxDamage(0);
setHasSubtypes(true);

}

public String getItemNameIS(ItemStack i) {
switch (i.getItemDamage()) {
case 0: return "Name 1";
case 1: return "Name 2";
case 2: return "Name 3";
case 3: return "Name 4";
case 4: return "Name 5";
case 5: return "Name 6";
case 6: return "Name 7";
case 7: return "Name 8";
case 8: return "Name 9";
case 9: return "Name 10"; }
return "";
}

public int getMetadata(int par1)
{
return par1;
}


@SideOnly(Side.CLIENT)
public int getIconFromDamage(int par1)
{
return YOURMAINMODCLASSHERE.metadataTestBlock.getBlockTextureFromSideAndMetadata(2, par1);
}
}

Once again you need to input your main mod class (Where you defined the new block) in getIconFromDamage(int par1) and in the switch statement in getItemNameIS() where there is 10 cases as you can see and you can remove or add cases up to case 15 : return "Name 15". Obviously these names are the just a unique ID but feel free to change them

Now we need to revisit the main file (where you defined the block) and add into the initialization part these two bits of code

public static String[] brickName = { "White","Red","Lime","Light Blue","Yellow","Purple","Green","Orange","Dark Green","Black"};
for(int i = 0; i < 10; i++) {
LanguageRegistry.addName(new ItemStack(metadataTestBlock,1,i),metadataTestBlockNames[i] + " Stone Brick");

}

and

GameRegistry.registerBlock(metadataTestBlock, MetadataTestBlockItem.class);

This adds the names using a for loop. I'm using a stone brick example which collects the name from the value of i in the loop aswell as cycling through the metadata ID at the same time. We then register the block using the MetadataTestBlockItem.Class that we wrote earlier in the code shown above. Now you should have all the blocks but we need to add it to creative so we add this code and then we are done:

metadataTestBlock.setCreativeTab(CreativeTabs.decoration);

Now we are done, Any errors please contact me either through a PM or a post and I will fix the tutorial where I see fit
