[NoOneButNo]

Huh does that even need to be elaborated? I just said that he can copy the method and paste it in whatever utility class (or what class he wants) as a static method then modify it a bit. I am not going to teach basic java here but for the sake of explanation, enchantments level is read as an integer idk why the addEnchantment method converts it into a byte and you can just modify it a bit so that it will no longer be casted into byte and short...

Well, I already know that. Manipulating the unbreaking enchantment gives many more opportunities that even other mods can be affected. Thanks for answering and have a good day.

Not if you copy and paste and modify ItemStack#addEnchantment method to a new utility class or whatever.

I wanted to modify the UnbreakingEnchantment#negateDamage method. If possible, no ASM. Can someone help me regarding this.

Take a look at the shulker box code. I believe it might help you.

Well, maybe for future reasons, such as "oh hey lets spam logs because its dev mod, and no, don't spam logs because this is not dev environment".

ok, thanks.

Is it possible to create a custom colored textformatting outside of the default one? like brown, indigo, etc.

launch.blackboard.get("fml.deobfuscatedenvironment") is missing in 1.14.4 forge. Now how to check if the mod runs in dev mode in 1.14.4

Well, sorry for being stupid.

Ohhh learned something new today.

Try allocating more RAM to minecraft.

Wait, by sending packets to server while already on the server, did you mean by: if(!world.isRemote) PacketHandler.INSTANCE.sendToServer(new MsgResetSwordSign());

Apparently, this crash only occurs if I call ItemSword#hitEntity. Is this an example of invalid thread?

If you were to give an example of that, what would it be? Never encountered that type of problem before.

Interesting, apparently commenting the decoration packets and the crash won't happen. I'll investigate more of this.

Ok I'll run a dry test while disabling those "decoration packets"

The Entity Slash is the only one who sends the packets

Okay, now that the supplied codes are provided, I will describe how it'll occur. The crash will be thrown if I attempt to lets say summon the EntitySlice 6x in a quick session (like for 3 seconds). If not spammed/quickly summoned, the probability of the crash reduces into infinitesimal(?). What is wrong with the code?

Report this to the author of thaumic additions.

Well, got used to boolean check hehe.

Ok, I'll try.

This is an example of an enchantment class I have: public class EnchantmentPenetratingEdge extends Enchantment { public EnchantmentPenetratingEdge() { super(Rarity.RARE, EnumEnchantmentType.DIGGER, new EntityEquipmentSlot[]{EntityEquipmentSlot.MAINHAND}); this.setName("PenetratingEdge"); this.setRegistryName("PenetratingEdge"); } @Override public int getMaxLevel() { return 6; } @Override public int getMinEnchantability(int par1) { return 16 + 12 * (par1 - 1); } @Override public int getMaxEnchantability(int par1) { return super.getMinEnchantability(par1) + 40; } @Override public boolean canApply(ItemStack fTest) { //Used this to find out if it yields true or false; turns out its useless //System.out.println(fTest.getItem() instanceof ItemAxe); return fTest.getItem() instanceof ItemAxe ? true : false; } }

I know that canApply method exists for Enchantment class, but the way it works isn't applicable for locking down to a specific Item. For example, I want an enchantment that can only be applicable to axes and not pickaxes but overriding this method does not work. A code wise example: @Override public boolean canApply(ItemStack stack) { return stack.getItem() instanceof ItemAxe ? true : false; } This works if the item enchanted in question is a sword for example however does not work if EnumEnchantmentType is DIGGER (Checking for a pickaxe against axe returns false but the enchantment table still allows player to enchant it as if its true).
