So I started up my client to test out this model I made for an item, however I crashed with this error:

ClientProxy stuff:

ItemRenderer file:

Staff code and clientproxy registering in my base file(Arcticraft.java)

 

public static Item staff;

@PreInit
public void preInit(FMLPreInitializationEvent event)
{
	proxy.registerRenderInformation();
        }

@Init
public void Init(FMLInitializationEvent event)
{
this.initItems();
}

public void initItems() 
{
	this.staff = (new AC_ItemStaff(1950).setItemName("staff").setIconCoord(13, 2));
}

 

AC_ItemStaff:


package arcticraft.items;

import arcticraft.entities.AC_EntityStaffBall;
import net.minecraft.src.*;

import net.minecraft.client.Minecraft;

public class AC_ItemStaff extends Item
{
public AC_ItemStaff(int par1)
{
	super(par1);
	this.maxStackSize = 1;
	maxStackSize = 1;	  //1 for durability | 1-64 for consumption	
	setMaxDamage(1000);    //Durability = # + 1
	setTabToDisplayOn(CreativeTabs.tabCombat);
}




public ItemStack onItemRightClick(ItemStack itemstack, World world, EntityPlayer entityplayer)
{
	if(entityplayer.capabilities.isCreativeMode)
	{
		world.playSoundAtEntity(entityplayer, "random.bow", 0.5F, 0.4F / (itemRand.nextFloat() * 0.4F + 0.8F));

		if (!world.isRemote)
		{
			world.spawnEntityInWorld(new AC_EntityStaffBall(world, entityplayer, entityplayer, iconIndex, iconIndex));
		}

		return itemstack;
	}

	if (entityplayer.ridingEntity != null)
	{
		return itemstack;
	}
	else
	{

		world.playSoundAtEntity(entityplayer, "random.bow", 0.5F, 0.4F / (itemRand.nextFloat() * 0.4F + 0.8F));

		if (!world.isRemote)
		{
			world.spawnEntityInWorld(new AC_EntityStaffBall(world, entityplayer, entityplayer, iconIndex, iconIndex));
		}

		itemstack.damageItem(1, entityplayer); 
		return itemstack;}
}


public String getTextureFile()
{
	return "/arcticraft/textures/ACItems.png";
}
}

 

And thats probably all the code you need to know about. But yeah, I need help on this!

    I liked the part where you tried to reference the item before you initalized the item.

    God that was hilarious.

    I do Forge for free, however the servers to run it arn't free, so anything is appreciated.
