emm well , my "Skill Class" :

 

package Items;

import java.util.List;

import ArturFarid.BlockUpdate.Util.ElementalConfig;
import net.minecraft.entity.Entity;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.item.Item;
import net.minecraft.item.Item.ToolMaterial;
import net.minecraft.item.ItemStack;
import net.minecraft.item.ItemSword;
import net.minecraft.util.EnumChatFormatting;
import net.minecraft.world.World;
import net.minecraftforge.fml.relauncher.Side;
import net.minecraftforge.fml.relauncher.SideOnly;

public class TestSkill extends ItemSword {

public TestSkill(Item.ToolMaterial m, String name) {
	super(m);
	setRegistryName(name);
}

public boolean onLeftClickEntity(ItemStack par1, EntityPlayer par2, Entity par3) {
	if (!par2.getEntityWorld().isRemote) {
		par3.setFire(ElementalConfig.swordAbilitiesControlledByExp ? par2.experienceLevel / 5 + 5 : 20);
	}
	return false;
}

@SideOnly(Side.CLIENT)
public void addInformation(ItemStack par1, EntityPlayer par2, List par3, boolean par4) {
	par3.add(EnumChatFormatting.RED + "BURN" + "!");
}
}

 

The Small stuff:

 

public static Item.ToolMaterial fire = EnumHelper.addToolMaterial("Fire", 10, 2000, 10.0F, 4.0F, 2);
public static TestSkill fireskill;
fireskill = new TestSkill (fire, "test");
GameRegistry.registerItem(fireskill, fireskill.getUnlocalizedName().substring(5)); //Here is the Error, if i set this as "comment" the game starts witouth problem
registerRender(fireskill);

 

and well the json is a normal test one:

 

{
"parent": "builtin/generated",
"textures": {
	"layer0": "blockupdate:item/fireskill"
},
"display": {
	"thirdperson": {
		"rotation": [ -90, 0, 0 ],
		"translation": [ 0, 1, -3 ],
		"scale": [ 0.55, 0.55, 0.55 ]
	},
	"firstperson": {
		"rotation": [ 0, -135, 25 ],
		"translation": [ 0, 4, 2 ],
		"scale": [ 1.7, 1.7, 1.7 ]
	}
}
}

Just so you know, the method GameRegistry.registerItem(Item item, String name), if you look at the GameRegistry.class, tells you strait up that in your item class, you are setting the registry name, yet you reset it again when you use that particular method. Just use GameRegistry.registerItem(Item item). that should work just fine, so in your case GameRegistry.registerItem(fireskill); You were just registering the name twice, so forge through the error.

It thinks your item is an 'ItemBlock' for some reason, I believe. Try setting the unlocalized name to something other than 'test'.

 

and don't do this: fireskill.getUnlocalizedName().substring(5))

 

Just change that to 'fireskill' and change the 'test' up above to 'fireskill' too.

Have a modding question? PM me and hopefully I'll be able to help. Good at 2d Pixel Art? We need your help!  http://www.minecraftforum.net/topic/1806355-looking-for-2d-pixel-artist/

Don't use 

getUnlocalizedName()

for registering the block, either use the registry name (

getRegistryName()

, or a custom name.

Don't PM me with questions. They will be ignored! Make a thread on the appropriate board for support.

1.7.10 and older versions of Minecraft are no longer supported due to it's age! Update to the latest version for support.

its not a block, its a Item :3

Derp...

 

Even though, you should still change over to the registry name.
