I'm attempting to develop a little mouse controller app. It should get (X, Y) coordinates and make the cursor go there.
The problem is that when it attempts going to an X coordinate smaller than the current one.
import win32con
from win32api import GetCursorPos, SetCursorPos, mouse_event, GetSystemMetrics
from time import sleep
def clickWithCursor(xDesired, yDesired):
xCurrent, yCurrent = GetCursorPos()
slope = float(yDesired - yCurrent) / float(xDesired - xCurrent)
def goAhead(x, y):
for x in range(min(xCurrent, xDesired), max(xDesired, xCurrent), 2):
y = int(slope * (x - xCurrent) + yCurrent)
SetCursorPos((int(x), y))
sleep(0.002)
mouse_event(win32con.MOUSEEVENTF_LEFTDOWN,x,y,0,0)
mouse_event(win32con.MOUSEEVENTF_LEFTUP,x,y,0,0)
return goAhead(0, 0)
def main():
clickWithCursor(243, 184)
main()
Above is just a very bad attempt to do so which does not give me the result I was looking for. I was looking all over how to do it and just could not find the right way.
In short, I wanna construct a list so it would go logically from bigger to smaller value, or smaller to bigger, according to paramerters order.
So, if I would give range(4, 1) which I want to be resulted in: [4, 3, 2] or range(1, 4), it would'nt mind and construct it the right way...
EDIT: I refactored the code according to the answers and made it more readable for other users to review. Note the "sequence" method in class MouseController:
from win32con import MOUSEEVENTF_LEFTDOWN, MOUSEEVENTF_LEFTUP
from win32api import GetCursorPos, SetCursorPos, mouse_event
from time import sleep
class CursorPositionPrinter(object):
"""docstring for CursorPositionPrinter"""
def print_cursor_pos(self):
print GetCursorPos()
def __init__(self):
super(CursorPositionPrinter, self).__init__()
class AutoClicker(object):
"""docstring for AutoClicker"""
def click(self, times):
xCurrent, yCurrent = GetCursorPos()
for i in xrange(times):
self.simple_click(xCurrent, yCurrent)
def simple_click(self, x, y):
mouse_event(MOUSEEVENTF_LEFTDOWN, x, y, 0, 0)
mouse_event(MOUSEEVENTF_LEFTUP, x, y, 0, 0)
def __init__(self):
super(AutoClicker, self).__init__()
class MouseController(CursorPositionPrinter, AutoClicker):
"""docstring for MouseController
Controlls your mouse magically!!!"""
def sequence(self, a, b, n):
mn, mx = a, b
step = -n if mn > mx else n
for value in xrange(mn, mx, step):
yield value
def click_with_cursor(self, xDesired, yDesired):
self.go_to_coordinates(xDesired, yDesired)
self.simple_click(xDesired, yDesired)
def go_to_coordinates(self, xDesired, yDesired):
xCurrent, yCurrent = GetCursorPos()
slope = float(yDesired - yCurrent) / float(xDesired - xCurrent)
for x in self.sequence(xCurrent, xDesired, 2):
y = int(slope * (x - xCurrent) + yCurrent)
SetCursorPos((int(x), y))
sleep(self.latency)
SetCursorPos((xDesired, yDesired))
def __init__(self, latency=0.02):
super(MouseController, self).__init__()
self.latency = latency
either go of a step of -1 or 1 depending on which value is greater after you get the min and max:
def up_down(a, b):
mn, mx = min(a), max(b)
step = -1 if mn > mx else 1
return range(mn, mx, step)
Output:
In [9]: list(up_down([4,5,5,7],[0,1]))
Out[9]: [4, 3, 2]
In [10]: list(up_down([0,1],[4,5,5,7] ))
Out[10]: [0, 1, 2, 3, 4, 5, 6]
If the min is greater we need a negative step, if not just use a step of 1.
To make it a little more obvious how to use the logic in your own code you simply have to use the if/else:
def goAhead(x, y,n=1):
step = -n if xCurrent > xDesired else n
for x in range(xCurrent, xDesired, step):
y = int(slope * (x - xCurrent) + yCurrent)
SetCursorPos((int(x), y))
sleep(0.002)
If you want to change the step size you can pass whatever n
you want
lim1, lim2 = 10, 2
step = 1 if lim1<lim2 else -1
lst = list(range(lim1, lim2, step))
print(lst)
=> [10, 9, 8, 7, 6, 5, 4, 3]
with:
lim1, lim2 = 2, 10
=> [2, 3, 4, 5, 6, 7, 8, 9]
This form allow:
list(range(lim1, lim2, 1 if lim1
range(a, b, -1 if a > b else 1)
