Now I just hope they will get a similar mechanic to Pigmen us being able to have them always be hostile. Now Jeb said that they only will be hostile if they have a cub near them.

Also the small possibility to have Battle Icebears?

we could hide some invisible cubs in the walls with resistance 4 to make them always angry. i am very excited. i have always wanted to fight a bear :^).

Well I tried, but it doesn't look good. Making one 1-wide/4-high tillable XOR gate for the adder was REALLY hard, although I did eventually get it. By that point the thing was already 14 blocks long, and I honestly cannot imagine trying to shove another similar XOR gate, (along with logic for the carry).

So as much as I think anybody would want a multiplier that is that compact, I'm afraid that it would be too slow and inefficient; maybe it's impossible.

well, thanks for your help. it is a bummer, I couldn't come up with any designs that worked either. oh well. :/

Sorry for taking so long to respond, but I think what you're looking for is a 2 x 4 x n full adder. I don't really understand how you want to use a half adder for your setup. Half adders have two inputs, and if linked together (with carries) they effectively only have one input per bit. Full adders however, have three, and if linked together, they will effectively have two.

It's a little weird, but basically, say you have 4 bits (1, 2, 4, 8). Linking them with half adders will only allow you to add one to the the 4 bits. With full adders, you could add one, AND add another 4 bits.

So is this what you want?

yeah, honestly I'm not sure what I was thinking when I said half adder. I think I meant full adder, but I could have just been being really stupid. thanks

I could try to come up with a design, but you would to show the outputs/inputs a bit more clearly; I'm absolutely sure I could make a half adder with the dimensions you need though.

Here, would this help? These are the outputs. They're color coded based on the power of two that they represent, from left to right. There's one block in between each column of outputs and there's one block between each row (this is where the redstone dust is).

So there's actually a much, much easier way of making a subtractor. All you need is a slightly modified adder. What you do is invert all of the B inputs, so that 1 = 0 and 0 = 1, and changing the Cin value to 1. This is called two's complement, and it's generally regarded as the best way to do "negative" numbers in binary. Here's an example:

I have 46 for my A input:

0 0 1 0 1 1 1 0

and I want to subtract my B input of 7:

0 0 0 0 0 1 1 1

so what I do is invert 7, which gives me:

1 1 1 1 1 0 0 0

and then I add 1 with the Cin:

1 1 1 1 1 0 0 1

then all I do is add these two numbers (00101110 and 11111001) together:

00101110

+ 11111001

and I get:

100100111

or, more correctly:

+00100111

(when you implement a subtractor, you interpret the Cout as the sign bit. If it's 1, the output is positive. If it's 0, the output is negative.)

which, if I convert back to decimal, is 39.

Basically, what two's complement lets you do is represent subtraction as simply the addition of a negative number.

All of that said, this is a really neat design, and I applaud you for your creativity. The comparator is also really neat. Good job!

I need a 2 wide tileable 4 tall half adder design for the binary multiplier that I'm building. I've spent a lot of time trying to figure one out, but none of my designs so far have fit. If anybody could give me a hand, I'd really appreciate it.
Here is the multipler in question:

Does anyone have experience working with World Machine and then importing the maps into WorldPainter? If so, how's the learning curve? Is it worth giving a shot, and is there anything in particular one should keep in mind when trying it?

the learning curve isn't too bad, but obviously your first few attempts will come out worse. just try to remember what you intended for it to look like, and start simple before you make your maps more complex.

So I'm back and it looks like the thread is dead.

Can you make a tutorial on how to install WorldEdit/SPC/TMI/AUW/any other useful mapmaking tools in 1.8/1.9/1.10?

100% serious I haven't been able to mapmake in any significant way since the new modding system.

Oh, was this the one where I was gonna build a lavatree and then forgot about it?

Whoa, why am I credited? Not complaining, just not sure what I did. Please keep me up there <3
