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: Point windMouse(int x, int y) Which comes directly from the SMART github with minor adjustments to work with DB3. Better in fixed mode. 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()); All credits go to Benjamin J.
