You can create your own enchantment class and declare it in your mod class

 

 

 

package claygolem.util;

import net.minecraft.enchantment.Enchantment;
import net.minecraft.enchantment.EnumEnchantmentType;

public class EnchantmentTest extends Enchantment {
    private static final String __OBFID = "CL_00000100";

    public EnchantmentTest(int effectID, int weight) {
        super(effectID, weight, EnumEnchantmentType.weapon);
        this.setName("testEnchantment");
    }

    /**
     * Returns the minimal value of enchantability needed on the enchantment level passed.
     */
    public int getMinEnchantability(int par1) {
        return 20;
    }

    /**
     * Returns the maximum value of enchantability nedded on the enchantment level passed.
     */
    public int getMaxEnchantability(int par1) {
        return 50;
    }

    /**
     * Returns the maximum level that the enchantment can have.
     */
    public int getMaxLevel() {
        return 1;
    }
}

 

 

 

in your mod class, add the following:

/** custom enchantment 'Test' */
public static final Enchantment test = new EnchantmentTest(113, 0);//id's may not conflict, maybe register the id in a config so it stays compatible with other mods.

how to make that enchantment usable?

Well you can write an event that triggers when the player hits an entity.

 

//I don't know which event it is, you would have to look it up yourself.

        EntityPlayer player = event.Player;
        ItemStack stack = player.inventory.getCurrentItem();
        if(stack != null && stack.isItemEnchanted()) {
        	if(EnchantmentHelper.getEnchantmentLevel(Enchantment.baneOfArthropods.effectId, stack) > 0)
        		System.out.println("BoA");//do effect
        }

 

Using the EnchantmentHelper class, you can check for all enchantments on the itemstack using EnchantmentHelper#getEnchantments this will return a hashmap.

I used it to combine effect, like if horse armor had fire aspect + some custom ones, do the following.
