A very simple AutoHotKey (AHK) script that tries to replicate the behaviour of WispY's AseBrush Java applet, as shown in AdamCYounis' awesome "Aseprite Crash Course" video!

Note: This is my first AutoHotKey script, so it's not quite ideal but it works well enough that I thought I'd share it. You're more than welcome to fork/PR any changes to improve this!

Hold the D key and move your mouse/pen in either the X or Y axis (default X axis, which can be changed in the AHK script version) to adjust the size of the brush whilst Aseprite is the active window!

You can toggle pausing the script by using the shortcut CTRL + ALT + D whilst Aseprite is the active window.

Note: The standalone version doesn't require AHK to be installed!

Download Latest Standalone Windows Binary (Created using Ahk2Exe, with MPRESS compression)

Running the downloaded .exe will run the script in the background and will only be interact with aseprite.exe when it's the active window.

Note: This script never installs as a program, it is fully portable, so if it doesn't work/you don't need/want it anymore, you can just delete the .exe you downloaded!

How to run the script can be read from the AHK documentation

• Fix issue with script sometimes scrolling rather than changing brush size (issue with tick rate being too high?)
• Still be able to type lowercase d (checks if the mouse moved below a configurable threshold (default: 4 pixels) or you can now use CTRL + ALT + D to toggle pause the script)
• Allow the script to increase the brush size in increments other than just one
• Change the config variables from the system tray (not sure if this is possible. If it is, also look into keeping it persistent)
• Just found out Aesprite scripting exists (even tho I've been using some extensions/scripts already, woops), try porting this into a script (would make it better + easier to use for everyone, including me!)
