Prerequisites: To create and edit your own patterns, you need to have a modern version of Adobe After Effects installed, as well as ahk itself, in addition to at least basic level knowledge of AHK scripting.
The patterns made using the old Python pattern generator didn’t quite work for me, so in pursuit of a better method I came up with this:
About the method: The idea is to use Adobe After Effects motion tracking feature to track the movement of an object that is static in the firing range, but starts moving on screen when firing because the gun's recoil moves the camera up. After Effects then outputs the opposite of the tracked pattern - meaning the pattern it shows you is the movement you have to do to stabilize the recoil.
My goal was to define a method that would output a decent to good recoil pattern out of the box without much need to mess with the numbers themselves.
How does the script work from start to finish: Adobe After effects outputs a big set of absolute coordinates based on your video resolution and framerate - 1080p 60 fps in this case.
The structure is: linenumber X Y
The script reads these from the .txt file provided and using some basic math converts them from absolute coordinates to relative offset in reference to your mouse cursor. The rest is identical to other ahk scripts in principle. To determine the waiting time between the mouse movements the overall firing time of the weapon gets divided by the amount of lines in the tracked pattern.txt
What is different is the fact that this script doesn’t do just one mouse movement per bullet, as old scripts did. It's neither ultimately better or worse, but it might be providing higher precision at the cost of sending a few times more mouse inputs.
By setting out2txt := 0 to 1, the script will automatically convert the raw After Effects pattern into the format used by old scripts.
!WARNING!
The following concerns the usage of old scripts that have recoil patterns embedded.
Due to the nature of the tracked patterns (After Effects scans video frames one-by-one and writes down any changes between them, resulting in up to 60 entries (read "potential mouse movements") per second, such amount of data exceeds the ahk per-expresseion limit and in order to avoid that the script should load the pattern from an external .txt, instead of having it as part of the main script itself. This has to be coded in, obviously.
