Boost ball functionality

[thelabcat]

I rewrote the Metroid Prime Hunters components of the mousefix for compatibility with my own PC and successfully implemented a way to do boost ball that I thought your code might benefit from. The basic strategy is to perform a quick swipe macro by pressing the tab key, and I also have it look at if any WASD keys are pressed to modify the swipe direction. Here is my Python code:

## CONFIG["directions"] is a dictionary of Cartesian coordinate vectors, [0, 1] being down, for example.
## self[key] queries configuration for this particular mousefix
## self["boostSwipeSize"] is a pixel length that comes from when I discovered that swipes on the touch screen have to be a certain size for the ROM to trigger a boost ball
## self.reset_mouse() picks up the mouse and moves it back to the center of the touch area
## self.goto_relative() moves the mouse cursor to a position of the touch area, relative to the size of the screenshots I used to make the fix[es]

    def boost_ball(self, e):
        """Perform a touch-based boost ball"""
        self.mouse_up()
        time.sleep(CONFIG["mouseResetWait"])
        
        direction=[0, 0]
        
        for d in CONFIG["emuKeys"]["dPad"].keys(): #Sum input CONFIG["directions"]. If they contradict, they will zero out
            if keyboard.is_pressed(CONFIG["emuKeys"]["dPad"][d]):
                #print(key)
                direction[0]+=CONFIG["directions"][d][0]
                direction[1]+=CONFIG["directions"][d][1]
                
        if direction == [0, 0]: #If there is no direction or all input CONFIG["directions"] cancelled out, use the default
            direction = CONFIG["directions"][self["defaultBBDirection"]]

        end_x = self.touch_center[0]+self["boostSwipeSize"]//2*direction[0]
        end_y = self.touch_center[1]+self["boostSwipeSize"]//2*direction[1]

        start_x = self.touch_center[0]-self["boostSwipeSize"]/2*direction[0]
        start_y = self.touch_center[1]-self["boostSwipeSize"]//2*direction[1]
        #print("Direction is", direction)
        #print("Boost from ", start_x, start_y, "to", end_x, end_y)
        self.goto_relative(start_x, start_y)
        time.sleep(CONFIG["mouseResetWait"])
        self.mouse_down()
        time.sleep(CONFIG["mouseResetWait"])
        self.goto_relative(end_x, end_y)
        time.sleep(CONFIG["mouseResetWait"])
        self.reset_mouse()

Hope this helps!
