  • WindMouse - Custom Mouse Movement Algorithm


    Recommended Posts

    Hey all,

    Since DB3 officially supports custom mouse algorithms I thought I would port over a classic one: WindMouse.

    WindMouse was written by BenLand100 for SCAR some years back (maybe 10 years?) and has been used on so many damn bots throughout the years because it functions really well so it only seemed right to bring it here.

    In the source code below, there are two implementations of WindMouse:

    1. Point windMouse(int x, int y)
      Which comes directly from the SMART github with minor adjustments to work with DB3.
      Better in fixed mode.
       
    2. void windMouse2(Point point)
      My tweaked version from years back that supports all screen sizes.
      I've added a random point between the original and the destination point if the distance between them is large to feel more human but has a 50% chance of happening.

    By default my implementation is the active algorithm (as it handles all sizes), swap the comments in handleMovement to change to the original.

     

    To use it, simply add the file WindMouse.java to your project and add the following to your onStart method:

    Client.getInstance().setMouseMovementAlgorithm(new WindMouse());

    Awesome work, thanks man! Will definitely give this a shot :)

    Thanks, Stoned! But really all the thanks should go to BenLand100, wherever he is these days, as I just modified it to my liking and to be more human-like ;)

    If anyone uses it in their scripts let me know, I'd love to see it in action. My script that uses it is simple so it's not a great demo. I have tested it thoroughly to make sure it works well, I just haven't seen it doing a lot of fast/complicated actions.

    Really neat, thank you for sharing this! I added it to one of my private scripts that does have a lot of fast/complicated mouse actions.  It's working great so far I can notice the mouse difference.  I'm still rather new here so I haven't released any scripts yet but I plan to.

    Doesn't seem to work with login handler for me.

    It's been working just fine for me, haven't tried it today though. Is it just not moving or what? What's going on?

    Could be a client issue.

    Its on DB3. I know everything else works. I only changed that one line of code. I disable the login handler to start with. Then manually with a button i enable it. Works fine with multi thread mouse setting, speed, hops, etc. But with that setmouse alg to that. it just poof no work. No error message or anything. It moves the mouse! But doesn't click. Which is awkward.

    EDIT: yeah it might be a db3 issue, idk. No console error messages though.
