Azurn

I had a few @SideOnly in my TileEntity files. Should i have them or should i not have them?

I do not think my folder structure is the problem. When i change it is says: cpw.mods.fml.common.LoaderException: java.lang.ClassNotFoundException: mods.castledef.azurn.mod_castledef instead of java.lang.NoClassDefFoundError: mods/CastleDef/Azurn/EntityKnight mod_castledef and entityKnight is in the same folder.

I have the exact same problem. It is driving me insane.

Im still having this problem and i have no idea on how to fix it.

I have the exact same problem. Worked in MCP but when installing it says : ava.lang.NoClassDefFoundError: mods/CastleDef/Azurn/EntityKnight Its driving me insane.

It was not that, but thanks anyway. Anyone else?

Yes, it is in mods/Castledef.zip/mods/CastleDef/Azurn Here is the code: package mods.CastleDef.Azurn; import java.util.Map; import javax.crypto.Mac; import mods.CastleDef.common.CommonProxyCastleDef;

Thanks!

Never mind, i solved it. added this to the mod_x file: RenderingRegistry.registerEntityRenderingHandler(EntityKnight.class, new RenderBiped(new ModelBiped(), 0.5F));

Hi! I need my custom mods to hold items. I have ofcourse looked at EntitySkeleton and EntityPigZombie and they use this line of code: protected void func_82164_bB() { this.setCurrentItemOrArmor(0, new ItemStack(Item.swordGold)); } This does not however work on my mobs. I have also tried this: public ItemStack getHeldItem() { return defaultHeldItem; } private static final ItemStack defaultHeldItem; static { defaultHeldItem = new ItemStack(Item.bow, 1); } That way has worked for me in the past but not now. Is there anything i need to add to the mod_x file? Can anyone help me with this? Thanks!
