I'm trying to get my custom Item accept ONLY SPECIFIC vanilla enchantments (unbreaking) in the enchanting table. I know that you can allow the tool enchantments to be added by making the items class extend ItemTool, but that would allow all tool enchantments, like silk touch,... , to be added to the item. Is there a way of only accepting a few of these enchants without modifying base classes?

Hi

 

After a quick look through the vanilla code I don't think there is anything you could do directly, but you might be able to get to the same place indirectly.  If you hijack the vanilla enchanting table using the GuiOpenEvent to replace the enchanting table GUI with one of your own which derives from GuiEnchantment, you could override mouseClicked to call a customContainerEnchantment which restricts the enchantments that can be applied.

 

If Draco reads this he might have more specific help, he's done a stack of stuff with enchantment.

The only enchantment stuff I did was using the inbuilt system.

 

Specifically I'd check what kind of item I had, or close approximation, modified a tiny bit randomly, then:

 

                ItemStack stack = new ItemStack(item); //the vanilla item that is similar to my item
                stack = EnchantmentHelper.addRandomEnchantment(rand, stack, level); //add enchantments per existing rules
                if(stack.stackTagCompound != null) {
                        artifact.stackTagCompound.setTag("ench", stack.stackTagCompound.getTag("ench").copy()); //copy enchantments to my item
                        //other stuff
                }

use the on update function to remove the enchantment what is not allowed. That is the only way when you still want to use the vanilla enchanting way.

For my enchanter i created a new enchanting system
