I improved the script and here it is!
Code: Select all
# Solid.py
# Makes soups and runs oscar until a ship is found
# Seemingly stupid but actually very useful and fast
# Mainly used for searching "Solid" ships in LTL since soups of the right size
# produce only 1 object and separation is not needed so oscar can be run.
# Best fit for solid LTL rules that have lower period oscs that stabilize quicker but can also be used for larger ranges.
# Beeps when a ship is found.
# By Saka with oscar.py code from Andrew Trevorrow.

Mostly just oscar.py
It has found quite a few ships, not released yet, still in my "Solid" folder.
How to use:
1. Use slowshipconvert.py in the top post (
here) to convert to the desired range.
2. (Optional) Tweak the limits a bit, +-5 or something.
3. Select an area to search. Make sure that a 50% fill of the area produces only 1 "donut" when you fill it or else oscar will get stuck if it finds a osc+ship or ship+ship. Expanding soups will be skipped using a "smart maxPop" I made.
4. Still selecting the area, run solid.py
5. Wait until a ship is found (It will beep because it uses g.exit)
TODO:
-Display approximate soups/sec
-After a set amount of failed soups, adjust the rule and start over
EDIT:
VERY FAST c/10o with a very thin core found with the script
Code: Select all
x = 28, y = 28, rule = R10,C0,M1,S154..256,B133..269,NM
12b3o$11b6o$10bob3o$11b5o$11b6o$10b7o$9b9o$9b10o$8b12o$7b14o$5b18o2bo$

Turns out the original slow ship rule has a 2c/542o!
Code: Select all
x = 24, y = 25, rule = R10,C0,M1,S154..262,B133..265,NM

. THis thread is for "solid" ships in LTL rules. Solid ships are ships that consists of a static core with "fire" on the edges that cause the static core to move. Most cores are donut shaped.
