[Addon] Mesecon "and" gate
Posted: Fri Mar 16, 2012 05:44Alright, so after awhile of messing around with Temperest's OGAM. I thought, why can't there be an "and" gate? So I got to work on it.
Here's the code! (note: this is an addon to temperest's code)
Screenshot of the AND and NAND gates that can be used.
How to install
Alright first you need to download mesecons from here
You will need to add this image to mesecons_textures > textures as "jeija_duali"
Now open up mesecons_temperest > init.lua
Then copy the code below, and paste all of it at the bottom of the init.lua file.
Save it and now you have your "and" gate!
I'm sorry that I suck with github, otherwise I could just add all of this to mesecon.
There is still a few issues, so don't go using it just yet.
Current problems
Bold = major problem
Updates:
Reworked check code. "if" checks still do not run.
0.1 released. Everything "works" from my tests. If you found any problems please post them here.
0.11: Minor node changes.

There is still a few issues, so don't go using it just yet.
Current problems
Bold = major problem
- The Duali node can be connected to one single powersource, which branched off mesecon to connect to two spots on the Duali
- power not turning off after one power source is turned off.
