Enchant Item/Armor on Crafting

[comfix]

Hi Guys,

on which way I can enchant items on crafting e.g. my Sword with Sharpness II or something else?

Thanks for help!

Sure you can.

 

Question is:

Do you want to add a specific enchantment manually or do you want to apply a random enchantment that is appropriate, or do you want to apply any random enchantment?

 

(I happen to be in the middle of working on this myself!)

Yea i want to add a specific enchantment on my tools and armor on crafting.

 

It should be 1 or 2 enchantents for an item e.g. Chestpalte with Protection and Projectile Protection and the tools with Efficiency.

A random one sounds interesting and makes my mod a little bit harder

 

But the item's should be still enchantable with the enchantment that was added by crafting the item.

 

I had a full set of armor and tools plus a bow.

Ok, this is fairly easy then.

 

public void onCreated(ItemStack par1ItemStack, World par2World, EntityPlayer par3EntityPlayer) {
    int level = 20; //pretend the player has 20 levels to spend
    par1ItemStack = EnchantmentHelper.addRandomEnchantment(new Random(), par1ItemStack, level);
}

 

In theory that should work.

There may be some helpers that need to be called to get your custom item recognized as valid [tool|bow|armor], I'm not sure.  My items are going about it slightly differently (as I'm using one item class that results in items with varying effects, so "is it a tool?" is dependent on NBT data) so I'm actually enchanting a vanilla pickaxe/sword/armor (as appropriate) and then copying the relevant NBT data over to my item:

 

			Item item = Item.pickaxeWood;
		//pick a random amount of experience to use.  Higher amounts are rarer.  Minimum 5.
		int level = 4;
		do {
			++level;
		} while(level < 30 && instance.rand.nextInt( != 0);
		//if it has the deal-damage effect, treat it as a sword
		if(effectsOnItem.contains(2) && instance.rand.nextBoolean()) {
		        //get item's material
			switch(artifact.stackTagCompound.getInteger("material")) {
				case 0:
					item = Item.swordWood;
					break;
				case 1:
					item = Item.swordStone;
					break;
				case 2:
					item = Item.swordIron;
					break;
				case 3:
					item = Item.swordGold;
					break;
				case 4:
					item = Item.swordDiamond;
					break;
			}
		}
		//else treat it as a tool (imperfect, but acceptable; armor not coded yet)
		else {
			switch(artifact.stackTagCompound.getInteger("material")) {
				case 0:
					item = Item.pickaxeWood;
					break;
				case 1:
					item = Item.pickaxeStone;
					break;
				case 2:
					item = Item.pickaxeIron;
					break;
				case 3:
					item = Item.pickaxeGold;
					break;
				case 4:
					item = Item.pickaxeDiamond;
					break;
			}
		}
		//enchant the sword/pickaxe
		ItemStack stack = new ItemStack(item);
		stack = EnchantmentHelper.addRandomEnchantment(instance.rand, stack, level);
		//copy the enchantment from the temporary item to the real item
		artifact.stackTagCompound.setTag("ench", stack.stackTagCompound.getTag("ench").copy());/code]

 

It's very easy if you are looking for a very specific enchantment, as ItemStack has this function:

 

 public void addEnchantment(Enchantment par1Enchantment, int par2){...}

 

Easy peasy!
