Iron Nuggets: They are like Gold Nuggets, except they drop from Zombies instead of Zombie Pigmen (Althrough at a reduced rate, as zombies are very common), with more of them dropping per equipment piece used by the killed zombie, which would equal to 150-200% of the ingots said gear would be worth, rounded up (so, for example, a zombie who spawned wearing an Iron Helmet would drop 8-10 nuggets on top of the natural chance to do so, and 20-50% of the total amount of nuggets which would be used to craft each piece of Chainmail armor), and would drop (9 as a minimum) from Iron Ore instead of itself when using Fortune on an iron ore block (To prevent duplication. The same would be done to Gold Ore).
Nuggets would be also able to be used to craft Chainmail Armor, making it a cheap alternative for the beginning of the game to Iron Armor (As for leather armor, it would be tweaked so it is actually useful), compasses (So they are cheaper, with the same change applying to clocks).
The easiest way to not make this have dupe glitches is increasing the clay blocks min yield .
I don´t understand. Due to how t is written, you seem to say that the easiest way to avoid that glutch would be to make clay blocks drop more clay, which would actually cause the bug to not need Fortune.
A better way to avoid it would be to make the game diferenciate player-placed and naturally-generated blocks.
In order to give pigs an use, they could be able to eat anything to breed, both to compensate for their lack of usefulness due to the fact that they only drop food, while requiring carrots to farm them, which puts them at a disadvantage as a breeding choice when compared to chickens (Which optionally require seeds, but don´t actually need any resources), cows (Which uses cheap wheat and also drop leather) and sheep (Which provide wool and mutton), so it is possible to turn some kinds of food into better ones, and to reflect the fact that, IRL, they aren´t exactly picky.
In other words, pigs would be easier to breed oth to compensate for their inefficiency and for realism (Mostly the former).
That it in order to circumvent a bug that can be seen by using cheats to get a stack of mushroom stew, which causes the game to think that the player is using only one stew, which causes the stew stack to turn into a single bowl. Cake doesn´t have that bug, as it isn´t coded to turn into another item.
There is really no need for cake to stack, plus you would get the icing from the cake below on your other cakes, therefore making a mess.
Every other food source stacks, they can be placed, and they are one of the most difficult foods to obtain. It shouldn´t be there just for an achievement, plus, there are a lot of other items which, according to that, shouldn´t stack, such as pumpkin pie (Which would make as much of a mess).
