Would it be possible to create a wire that acts like redstone but has three states(negative, nuetral, positive)?

Specifiy please.

u mean a cable with negative redstone power?

Neoredstone is a new logic material, different to redstone. Unlike redstone that has two useful states ("off" and "on"), neoredstone has 3 useful states ("positive", "neutral" and "negative"). Neoredstone has no weak signal. Only a positive neoredstone signal can send an "on" signal, you can make mixed logical circuits of neoredstone and redstone. A positive neoredstone signal can power redstone and other machines(piston, dropper, door, etc).

 

 

what exactly would the negative signal do?

and what would neutral do? nothing?

 

EDIT: Take a look at the Redstone class. There is a lot of things to read that might already solve ur questions

A negative signal would negate a positive signal to a neutral signal.

 

Side note:

Redstone is binary ("0" or "1")

Neoredstone is trinary ("-1", "0", "1")

To answer your question, yes should be possible.

Keep in mind that you're limited to 4 bits of data per block unless you use a

TileEntity

. Redstone wire uses all 4 bits to store the 16 possible strength levels; storing the sign would take up 2 bits, leaving you with 2 bits to store 4 possible strength levels.

 

A non-ticking

TileEntity

(the default in 1.8

) probably wouldn't hurt performance too much, but you'll want to do some profiling to confirm that.

 

Edit: Actually, you probably don't need an explicit neutral sign (since that would just be 0 strength); so you can store the sign in 1 bit and use 3 bits to store 7 strength values.
