AHK Script to Focus a Program Automatically on Joystick Input

Personally I’m using it for Elite: Dangerous, but it’s generic in nature and you can use it for whatever thing you want.

I made it as a replacement for ED:Runner because that a) needs to be run as Admin and I don’t like that and b) it kept randomly and silently crashing on me, defeating its purpose.

Features

• runs in the background and watches for the configured application
• starts tools you need with the application when it’s up
• (optional) kills the tools again when it’s down
• when it’s up, watches configured devices for input and focuses the application if you move the X/Y axis or hit a button

Requirements

Running from Source

If you have AutoHotKey (1.1.x) installed, you can just run the script from source. Obviously needs AutoHotKey installed.

Using the Executable

If you don’t want to install AutoHotKey and/or want something that “just works”, there is a compiled .exe on the releases page.

Settings

Before running the script for the first time, you need to create a focus.ini file or rename the included focus.example.ini to that. It contains my personal settings if you want to go off those as a base. Which is exactly what I’ll be doing here to explain things.

Target Application

[target]
name="EliteDangerous64.exe"

The name of the executable the script should be monitoring for. In case of Elite: Dangerous, that is EliteDangerous64.exe.

Polling Rates

[polling]
pollingrate=100
targetcheckrate=5000

pollingrate (in ms) here is the interval at which to check for input on the configured devices. targetcheckrate (also in ms) is the rate at which the script will check if the target application is running. This is less time-critical as it will probably take a couple seconds to fully start anyway.

The lower you set the polling rates, the more CPU it will cost to keep the script running in the background but also the snappier it will react to inputs. If you feel like 100 ms are too slow, set a delay that’s smaller.

Device Settings

[devices]
name1="2Joy"
name2="4Joy"
sensitivity1=10
sensitivity2=1
threshold=5

In this section of the config file you are defining the devices the script should be monitoring.

name1 through nameX are the names in AHK terms, with Joy or 1Joy being the first in the list. You’ll probably have to go through them in sequence to find out which physical device is which number. The ordering MIGHT change after you reboot the system but has been consistent for me so far. It should definitely change if you reboot with one of the devices unplugged.

sensitivity1 through sensitivityX is a multiplier used for the axis inputs of the device with the same number as above. If you do not have set any curves for your device(s), you should probably leave this at 1 for all of them. Personally I have a very non-aggressive curve on my right stick, so that ones multiplier is cranked all the way up to 10.

Last but not least, threshold will be the intensity of input needed on an axis to trigger the script to focus your application. 5 means a 10% movement up or down an axis since the entire range of movement is 0 to 100, with 50 being resting position. If your device is “wobbly” and needs a huge dead zone in order not to produce ghost inputs, you might have to increase this.

Tools Settings

[tools]
path1="C:\Program Files (x86)\EDMarketConnector\EDMarketConnector.exe"
path2="D:\Tools\SSChanger\SSChanger.exe"
kill=True

Here you can set tools the script should run alongside your application.

path1 to pathX has to be set to the full paths of the tools.

kill is a boolean (True/False) to tell the script whether to kill the tools again after your target application has shut down. If you want them to stay open, just set this to False.

If you run into any errors, please try running the profile in question on its own / get a fresh version. If that doesn’t fix the error, look at the devel branch and see if it’s fixed there already.

If you have no idea what I was saying in that last parargraph and / or the things mentioned there don’t fix your problem, please file an issue. Thanks! :)

You can also say “Hi” on Discord if that is your thing.
