Random Crafting Recipe

[Moocowett]

I have an item called Enchantment Shard, and I want to make it so that when I craft 4 around a book, it gives a random level 1 Enchanted book. Currently, I have, in pre-init,

 

GameRegistry.addRecipe(new EnchantShardHandler(enchantshard));

 

EnchantShardHandler looks like this:

 

 

 

public class EnchantShardHandler implements IRecipe{

 

private ItemStack book;

 

public EnchantShardHandler(Item enchantshard){

GameRegistry.addRecipe(getRecipeOutput(), new Object[]{

" A ",

"ABA",

" A ",

'A', enchantshard, 'B', Items.book

});

}

 

@Override

public boolean matches(InventoryCrafting p_77569_1_, World p_77569_2_) {

if(this.equals(p_77569_1_))

return true;

else

return false;

}

 

@Override

public ItemStack getCraftingResult(InventoryCrafting p_77572_1_) {

return null;

}

 

@Override

public int getRecipeSize() {

// TODO Auto-generated method stub

return 3;

}

 

@Override

public ItemStack getRecipeOutput() {

book = new ItemStack(Items.book);

int i = (int) (Math.random() * 22);

 

if(i == 0){

book.addEnchantment(Enchantment.protection, 1);

}else if(i == 1){

book.addEnchantment(Enchantment.fireProtection, 1);

}else if(i == 2){

book.addEnchantment(Enchantment.featherFalling, 1);

}else if(i == 3){

book.addEnchantment(Enchantment.blastProtection, 1);

}else if(i == 4){

book.addEnchantment(Enchantment.projectileProtection, 1);

}else if(i == 5){

book.addEnchantment(Enchantment.respiration, 1);

}else if(i == 6){

book.addEnchantment(Enchantment.aquaAffinity, 1);

}else if(i == 7){

book.addEnchantment(Enchantment.thorns, 1);

}else if(i == {

book.addEnchantment(Enchantment.sharpness, 1);

}else if(i == 9){

book.addEnchantment(Enchantment.smite, 1);

}else if(i == 10){

book.addEnchantment(Enchantment.baneOfArthropods, 1);

}else if(i == 11){

book.addEnchantment(Enchantment.knockback, 1);

}else if(i == 12){

book.addEnchantment(Enchantment.fireAspect, 1);

}else if(i == 13){

book.addEnchantment(Enchantment.looting, 1);

}else if(i == 14){

book.addEnchantment(Enchantment.efficiency, 1);

}else if(i == 15){

book.addEnchantment(Enchantment.silkTouch, 1);

}else if(i == 16){

book.addEnchantment(Enchantment.unbreaking, 1);

}else if(i == 17){

book.addEnchantment(Enchantment.fortune, 1);

}else if(i == 18){

book.addEnchantment(Enchantment.power, 1);

}else if(i == 19){

book.addEnchantment(Enchantment.punch, 1);

}else if(i == 20){

book.addEnchantment(Enchantment.flame, 1);

}else if(i == 21){

book.addEnchantment(Enchantment.infinity, 1);

}

return book;

}

 

public ItemStack changeBook(){

return getRecipeOutput();

}

 

}

 

 

 

 

I currently have it made so that, when I craft the enchanted book, it is the same until I start minecraft again. Then it makes it different. For instance, I will run my mod, and craft the recipe, and I get an Efficiency 1 book. Then I craft it again, and it always is Efficiency 1. I reboot the game, and it gives me Punch 1 each time.

I have no idea how to make the recipe change output each time.
