The Autowiggler

Breath of the Wild has a trick known as Bow Lift Smuggle Sliding (BLSS) which involves one having to wiggle the stick back and forth rapidly in order to gain speed
Unfortunately I am terrible at this so one day I created a tool to help me with this (mostly out of boredom)

Here it is in action:

It also works well in the Wind Waker HD/Twilight Princess HD with spectacular results (video here)

To achieved this I used the Python modules pygame (for controller input) and vgamepad (as the virtual controller), as
I didn't want to take the time to learn the C++ api for ViGEm (Perhaps I will in the future but the python version works perfectly well for me at the moment). I use a similar concept in my TAS-Script interpreter

I've set the trigger for wiggling as D-Pad down; the Y position of the left stick behaves like normal but the X position alternates between left and right at the rate specified in line 12 of the code

Usage on Cemu or other emulators/games is simple enough but for Switch/Console I use this adapter

The code

The code is quite simple as it doesn't need to be 100% stable at the moment. However if anyone wants to use it the current script is as follows:

import vgamepad as vg 
import sys
from math import*
import pygame
clock = pygame.time.Clock()


pygame.init()
joysticks = []
keepPlaying = True
pro = 1 # Set to 0 if using an xbox controller or something; I used a Pro Controller with BetterJoy so there are 2 controller instances

WIGGLEDELAY = 4
"""
Change this to fit how many frames you want for the stick to make one iteration
For BotW I like 4 (2 left, 2 right) but for other games (WW/TP/etc.) 2 is usually better
"""

print(pygame.joystick.get_count())
for i in range(pro, pygame.joystick.get_count()):
  joysticks.append(pygame.joystick.Joystick(i))
  joysticks[-1].init()
  print ("Detected joystick "),joysticks[-1].get_name(),"'"

gamepad = vg.VX360Gamepad()
l=[0,0]
i=0
b=False
while keepPlaying:
  pygame.event.get()
  clock.tick(30)
  i=(i+1)%8
  gamepad.reset()
  if joysticks[0].get_button(0):
    gamepad.press_button(vg.XUSB_BUTTON.XUSB_GAMEPAD_A)
  if joysticks[0].get_button(1):
    gamepad.press_button(vg.XUSB_BUTTON.XUSB_GAMEPAD_B)

    gamepad.press_button(vg.XUSB_BUTTON.XUSB_GAMEPAD_X)

    gamepad.press_button(vg.XUSB_BUTTON.XUSB_GAMEPAD_Y)
    
  if joysticks[0].get_button(4):
    gamepad.press_button(vg.XUSB_BUTTON.XUSB_GAMEPAD_LEFT_SHOULDER)
  if joysticks[0].get_button(5):
    gamepad.press_button(vg.XUSB_BUTTON.XUSB_GAMEPAD_RIGHT_SHOULDER)

  if joysticks[0].get_button(6):
    gamepad.press_button(vg.XUSB_BUTTON.XUSB_GAMEPAD_BACK)
  if joysticks[0].get_button(7):
    gamepad.press_button(vg.XUSB_BUTTON.XUSB_GAMEPAD_START)
    
  if joysticks[0].get_hat(0)[0] == 1:
    gamepad.press_button(vg.XUSB_BUTTON.XUSB_GAMEPAD_DPAD_RIGHT)
  if joysticks[0].get_hat(0)[1] == 1:
    gamepad.press_button(vg.XUSB_BUTTON.XUSB_GAMEPAD_DPAD_UP)

  # if joysticks[0].get_hat(0)[1] == -1:
    # gamepad.press_button(vg.XUSB_BUTTON.XUSB_GAMEPAD_DPAD_DOWN)

    #IN USE FOR WIGGLING
  if joysticks[0].get_axis(4) > 0:
    gamepad.left_trigger_float(value_float=1)
  if joysticks[0].get_axis(5) > 0:
    gamepad.right_trigger_float(value_float=1)
  


  if joysticks[0].get_hat(0)[1] == -1:
    b=True
  else:
    b=False

  if not b:
    l = [joysticks[0].get_axis(0), -1*joysticks[0].get_axis(1)]
  else:
    n = -1 if i%WIGGLEDELAY>(WIGGLEDELAY/2 - 1) else 1
    l = [n ,-1*joysticks[0].get_axis(1)]
    
  gamepad.left_joystick_float(l[0], l[1])
  gamepad.right_joystick_float(joysticks[0].get_axis(2), -1*joysticks[0].get_axis(3))
  gamepad.update()

As you can see it is quite crude but it does the job :)
