Here's is a new version of the script.
This time it compacts the holes in the Printer by 308 cells back.
Code: Select all
# BitMap Printer - p154 Loafer Gun - Mirrored Engine
# User Choices :
# - Scrolling direction.
# - Initialisation (all gliders inner loops and 1rst frame getting out).
# - Eater Wall (or not) placement.
#
# HOW TO :
# Select a 2 states pattern.
# Run the script.
# Enter a configuration string : <scrolling><init><distance>
# scrolling = single letter : 'U', 'D', 'L' or 'R' (Up, Down, Left or Right).
# init = single symbol : '+' or '-' Initialise the Printer or not (+ = initialise).
# distance = positive integer : distance in percentage of BitMap's width to place the Eater Wall (0 = no Eater Wall).
#
# You to have include spaces between frames in your BitMap selection.
# There isn't any gun included for empty lines (scrolling direction).
# So holes can appear in the BitMap Printer.
# The empty lines on each edge (scrolling direction) allow the number of guns on each side to be shifted.
# This means that you can retrieve a one-side Printer at the extreme.
#
# Minimal BitMap Output Width = 7
# Spaces are added (up to a total of 7) on the right for BitMap's Width < 7
#
# HOW IT WORKS :
# Gun array offset -316,25 de-phased 98 ticks from previous gun.
# 4 basic loops to cover all BitMap widths (bits in loop : 7+4n, 8+4n, 9+4n or 10+4n).
# Trombones slides management :
# Get the minimum needed number of trombones slides (back and forth).
# Adjust the maximum of last NE slides to get a better bounding box.
# Add an inserter for each loop.
# Add the external input Gliders streams (with Synchronization).
# Compact if holes appear (308 cells back for each hole).
# If required :
# Run until BitMap Printer is initialized.
# Remove the inserters.
# Add the Eater Wall
#
# From an original idea of Otismo and its beginnings.

Enjoy ! I feel the script is finished.
Of course, some optimizations can be done and surely it can be rewritten with a better code …
A NW-SW Snark selected with 3 empty upper lines and some spaces at left (46x26), user string input = R+100
.
Strangely enough, as it happens in the first version of the script in this thread, no one has reported this error, as if this Glider was never used.
