Elite:Dangerous: Titan-Bomber Script

#!/usr/bin/env python3

##### What is this #####

# I made a simple python script to help with boosting away from interdiction's and bombing/rocketing the titan.
# What this script does is very simple. It repeatedly presses your boost key while you are holding it down.
# And if Scroll Lock is toggled on, then Right Mouse Button becomes full auto.
#
# If you are using an SCO FSD then i have an alternate version of the main() function for you to use.
# It changes Scroll Lock to act as a global on/off key for the whole script.
# Its a little more tedious to use since you need to turn the script on when using thrusters (if you want auto-boost)
# and definitely off when using supercruise. I think this made SCO FSD even more annoying to run xD
#
# For reference here is my titan-bomber fire groups indicating what RMB is assigned to.
# In firegroup C and D i use '(2)' for Nanite Torpedo Pylon and AX Missile Rack.
# To prevent TG Pulse Neutraliser from discharging incorrectly prior to entering the titan cloud
# keep Scroll Lock off until you are through the caustic cloud. After that you can keep Scroll Lock on.
# The Nanite Torpedo Pylon will not fire until you have a lock,
# and it feels like firing, so you can focus on flying + targeting with RMB held down and it will auto-click for you.
# Also the AX Missile Rack is full auto now for when its time to shoot the exposed core :D
#

##### Installation #####
# To run this script you need Python installed. After that run cmd as administrator > [pip install pynput] because that library is also needed.
# Save this script as a .py file, e.g. "Titan Script.py" and double click the file to run it.
# Also, unless you are also using Caps Lock as a boost key then you'll probably want to mod this line "boost_button = Key.caps_lock".

##### How to use this script when titan bombing #####
# 1. When you jump into a titan system make sure Scroll Lock is toggled OFF (LED off).
#    This disables the RMB autofire feature.
#    We don't want to accidentally autofire whatever you have bound to mouse-2 right now, e.g. TG Pulse Neutraliser, Heatsinks, Caustic sinks etc.
#
# 2. When interdicted keep your boost key held down with all pips to engines.
#    No need to spam the boost key like you're having a seizure, the script will handle it.
#
# 3. When you are through the malestrom cloud and at the titan, toggle ON Scroll Lock (LED on) to enable RMB autofire.
#
# 4. Switch to your Beam Laser + Nanite Torpedo fire group and commence to torpedo the thermal vents.
#    Lock on to thermal vents and hold RMB. The Nanite Torpedo will only fire when you get close.
#    No need to spam RMB.
#
# 5. Now switch to your Beam Laser + AX Missile Rack fire group and fly to the exposed core.
#    Your rockets will fire as fast as the game allows, just hold down RMB and watch the fireworks.
#
# 6. Fly away to avoid the blue radiation attack, and repeat steps 4+.
