Im trying to run my mod outside of mcp on minecraft with forge installed.

but when i run minecraft im getting this error.

http://pastebin.com/pfHspcZj#

does anyone knows how to fix that?

i did reobfuscate my code.

and this is my creativeTab code

public static CreativeTabs tabBlocks = new CreativeTab("Blocks", 7);
public static CreativeTabs tabRecipes = new CreativeTab("Recipe's", 1);
public static CreativeTabs tabQuest = new CreativeTab("Quest", ;
public static CreativeTabs tabJewelry = new CreativeTab("Jewelry", 2);
public static CreativeTabs tabMisc = new CreativeTab("Miscellaneous", 3);
public static CreativeTabs tabTools = new CreativeTab("Tools", 6);
public static CreativeTabs tabArmor = new CreativeTab("Armor", 4);
public static CreativeTabs tabWeapons = new CreativeTab("Weapons", 5);
public static CreativeTabs tabConsumables = new CreativeTab("Consumables", 9);
public static CreativeTabs tabMaterials = new CreativeTab("Materials", 0);

 

and for example in a item class:

public ItemBasicFood(int i, int j, float b) {
	super(i, j, b, true);
	res = j;
	sat = b;
	this.setCreativeTab(BaseLegendz.tabConsumables);
}

 

and my creative tab code:

package legendz.common;

import net.minecraft.creativetab.CreativeTabs;
import net.minecraft.item.ItemStack;

public class CreativeTab extends CreativeTabs{

private int ID;

public CreativeTab(String label, int id) {
	super(label);
	ID = id;
}

@Override
public ItemStack getIconItemStack() {
	switch(ID){
	default:
		return null;

	case 0:
		return new ItemStack(BaseLegendz.gemItem, 1, 0);

	case 1:
		return new ItemStack(BaseLegendz.recipeItem, 1, 0);

	case 2:
		return new ItemStack(BaseLegendz.earringItem, 1, 0);

	case 3:
		return new ItemStack(BaseLegendz.portalIgniter, 1, 0);

	case 4:
		return new ItemStack(BaseLegendz.aquaticChest, 1, 0);

	case 5:
		return new ItemStack(BaseLegendz.frozenFlamesBlade);

	case 6:
		return new ItemStack(BaseLegendz.energyPickaxe);

	case 7:
		return new ItemStack(BaseLegendz.legendzCraftingTable);

	case 8:
		return new ItemStack(BaseLegendz.questItem, 1, 0);

	case 9:
		return new ItemStack(BaseLegendz.mammothMeatItem);
	}
}

}

what do you excactly mean by reobfuscate?

i executed the bat file reobfuscate.

is that what you meant?

 

and what parts of the code you need?

did you grab reobfuscated classes (reobf directory)?

yes i got the classes from the there.

i out my main source file and put them in a zip.

i also coppied my textures from my resources and put them in the same zip file.

this worked with some of my previous mods but now it doesnt.

This may not be needed, but for my creative tab I had to also add another method, which is as follows.

LanguageRegistry.instance().addStringLocalization("itemGroup.TabName", "en_US", "Name Displayed In-game");

not setting a title does not cuase a crash (tested).

the error

java.lang.NoClassDefFoundError: net/minecraft/creativetab/CreativeTabs

cannot be interpreted many ways. it surely looks like obfuscation didn't happen...

i solved it.

some classes weren't obfuscated.

dont know how this happens but after a few times recompilen and reobfuscating i finnaly got a working mod

maybe a fresh mcp will prevent any future issue's.
