Trying to get PyAutoGUI to press both z button and x button at the same time on the keyboard causes an error. It assumes the second entry is presses, but it's not.
I have refered to the official documentation and accordingly this should work, yet fails.
import pyautogui
from time import sleep
x = 0
stop = 10
while x < stop:
pyautogui.press('z', 'x')
sleep(0.1)
x+=1
From Official Documentation:
To press multiple keys similar to what write() does, pass a list of strings to press(). For example:
pyautogui.press(['left', 'left', 'left'])
Or you can set how many presses left:
pyautogui.press('left', presses=3)
My bad, my eyes failed to see the [ ]'s, and now it works. Answered my own question.
import pyautogui
from time import sleep
x = 0
stop = 10
while x < stop:
pyautogui.press(['z', 'x'])
sleep(0.1)
x+=1

With pyautogui I'm trying to locate a object in a screenshot that is being taken but I can't find a way
from pyautogui import *
import pyautogui
import time
import keyboard
import random
import win32api, win32con
time.sleep(2)
ims = pica = pyautogui.screenshot(region=(569,381,800,450))
iml = pyautogui.screenshot(region=(1040,295,100,30))
def click(x,y):
win32api.SetCursorPos((x,y))
win32api.mouse_event(win32con.MOUSEEVENTF_LEFTDOWN,0,0)
win32api.mouse_event(win32con.MOUSEEVENTF_LEFTUP,0,0)
#Color of center: (255, 219, 195)
while keyboard.is_pressed('q') == False:
flag = 0
pyautogui.screenshot(region=(1040,295,100,30))
ims.save(r"C:\Users\Billy Bong\Desktop\python\saveimage.png")
pica = pyautogui.screenshot(region=(569,381,800,450))
ims.save(r"C:\Users\Billy Bong\Desktop\python\saveimage2.png")
time.sleep (2)
pyautogui.locateAllOnScreen("saveimage.png", confidence=0.6)
print (cords)
pyautogui.click (cords)
time.sleep (10)
break
Here is the minimal code for locating an object on the screen, you should have the image of the object.
import pyautogui as py
import keyboard
while True:
img = py.locateOnScreen("object.png", confidence=0.9) # add path to your object image here
print(img)
if keyboard.is_pressed('q'):
break
there is something i found out about pyautogui if u gonna use locateonscreen or locateallonscreen the image u asking him to locate must be in same folder u running the script from (according to my experience from using VS-code) and idk if there is a way to tell it to set a path for the image u wanna search to (something) so for the current time make sure u include all images u search for in same folder that the script is running from for me it is (E:\coding\game) cuz i make auto bots for games i like
btw locateallonscreenn prints out a list, the "cords" but idk if "pyautogui.click (cords)
" understand that and if it is going to click all the x,y in cords or not
I have read this question, which is similar and gets me most of the way.
The answer of the code isn't posted, but I believe I have followed the instructions and managed to get it working -- except after it's been opened.
It works perfectly fine immediately after recording, however I want to save the data and read it again for later use: literally every time I run the program and I don't want to have to re-record it every time.
import keyboard
import threading
from keyboard import KeyboardEvent
import time
import json
def record(file='record.txt'):
f = open(file, 'w+')
keyboard_events = []
keyboard.start_recording()
starttime = time.time()
keyboard.wait('esc')
keyboard_events = keyboard.stop_recording()
print(starttime, file=f)
for kevent in range(0, len(keyboard_events)):
print(keyboard_events[kevent].to_json(), file = f)
f.close()
def play(file="record.txt", speed = 1):
f = open(file, 'r')
lines = f.readlines()
f.close()
keyboard_events = []
for index in range(1,len(lines)):
keyboard_events.append(keyboard.KeyboardEvent(**json.loads(lines[index])))
starttime = float(lines[0])
keyboard_time_interval = keyboard_events[0].time - starttime
keyboard_time_interval /= speed
k_thread = threading.Thread(target = lambda : time.sleep(keyboard_time_interval) == keyboard.play(keyboard_events, speed_factor=speed) )
k_thread.start()
k_thread.join()
I am not especially new to coding, or the Python language, but this problem perplexes me. I've tested all the variables and none of them are being sustained outside of the record function.
(I don't fully understand lambda, Threading or **json.loads, but I don't think that's a problem.)
What's going on here?
For extra bonus points, if this is possible to do asynchronously, that'd be amazing. One problem at a time, though.
Just in case anyone else ever has the same problem as me, just tag this at the start of your code. No idea why it works, but it does.
keyboard.start_recording()
temp = keyboard.stop_recording()
You can forget about the temp variable immediately.
So I grabbed latest code from https://github.com/bulletphysics/pybullet_robots
I modified laikago.py example to the following, I'm only controlling one joint using torque.
Strangely enough poor robot flies away from the scene :)
There are two ways to fix it: either decrease simulation time step (line 10) or change torque value to 60 (line 33).
Any ideas what am I doing wrong?
import pybullet as p
import time
import os
os.chdir(os.path.dirname(os.path.abspath(__file__)))
p.connect(p.GUI)
plane = p.loadURDF("data/plane.urdf")
p.setGravity(0,0,-9.8)
timeStep = 1./300 # HERE!!! changing it to 1./400 fixes the problem
p.setTimeStep(timeStep)
urdfFlags = p.URDF_USE_SELF_COLLISION
quadruped = p.loadURDF("laikago/laikago_toes.urdf",[0,0,.5],[0,0.5,0.5,0], flags = urdfFlags,useFixedBase=False)
#enable collision between lower legs (2,5,8 and 11)
lower_legs = [2,5,8,11]
for l0 in lower_legs:
for l1 in lower_legs:
if (l1>l0):
p.setCollisionFilterPair(quadruped, quadruped, l0, l1, 1)
#set damping
for j in range (p.getNumJoints(quadruped)):
p.changeDynamics(quadruped, j, linearDamping=0, angularDamping=100)
p.setJointMotorControl2(quadruped, j, p.VELOCITY_CONTROL, force=0)
#run the simulation
p.setRealTimeSimulation(0)
for i in range (1000):
p.setJointMotorControl2(quadruped, 13, p.TORQUE_CONTROL, force=62) # HERE!!! changing it to force=60 fixes the problem
p.stepSimulation()
time.sleep(timeStep)
I am a bit late to the party, but maybe you are still in search of an answer. The reason is given here: https://pybullet.org/Bullet/phpBB3/viewtopic.php?t=12644 and a note was added to: https://docs.google.com/document/d/10sXEhzFRSnvFcl3XxNGhnD4N2SedqwdAvK3dsihxVUA/edit#heading=h.jxof6bt5vhut
The reason: "You need to first unlock/disable the default velocity/position motor. [...] Otherwise, your force/torque has to exceed the default motor." (see first link).
To fix do (same link):
pybullet.setJointMotorControl2(objUid, linkIndex, p.VELOCITY_CONTROL, force=0)
This is about unit testing (using Python's unittest module). I'm trying to implement, programmatically, the user's pressing "F2" to start editing the cell of a JTable.
The utility method "run_in_edt" wraps the passed method in a Runnable and then runs it using invokeAndWait, rather than invokeLater.
def test_can_edit_table_date(self):
main_frame = FTCase2.app.main_frame
dates_table = main_frame.dates_table
def start_editing():
dates_table.requestFocus()
f2_key_stroke = javax.swing.KeyStroke.getKeyStroke( java.awt.event.KeyEvent.VK_F2, 0 )
im = dates_table.getInputMap( javax.swing.JComponent.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT )
action_value = im.get( f2_key_stroke )
self.assertEqual( action_value, 'startEditing' )
am = dates_table.actionMap
self.f2_action = am.get( action_value )
self.assertIsNotNone( self.f2_action )
sel_row = dates_table.selectedRow
self.assertNotEqual( sel_row, -1 )
self.assertTrue( dates_table.isCellEditable( sel_row, 0 ))
self.start_editing_action_event = java.awt.event.ActionEvent( dates_table,
java.awt.event.ActionEvent.ACTION_FIRST, 'X' )
self.f2_action.actionPerformed( self.start_editing_action_event )
# dates_table.editCellAt( sel_row, 0 )
# self.assertTrue( dates_table.editing )
_utils.run_in_edt( start_editing )
# time.sleep( 1 )
def write_string_in_cell_editor():
self.assertTrue( dates_table.editing )
cell_editor = dates_table.cellEditor
self.assertIsNotNone( cell_editor )
cell_value = cell_editor.cellEditorValue
cell_editor.component.text = "mouse"
self.f2_action.actionPerformed( self.start_editing_action_event)
_utils.run_in_edt( write_string_in_cell_editor )
The problem: "dates_table.editing" always comes out false... and getting the cell editor returns None. I have also tried putting a sleep between these two Runnables, just in case it was a question of "events having to bubble up/down"...
NB I also tried with a more sensible value as the 3rd param of ActionEvent, such as action_value (i.e. 'startEditing'). No joy.
I can of course do:
dates_table.editCellAt( sel_row, 0 )
... with this uncommented, what's interesting is that, in the second method here, I set the JTextField's ("editor delegate") text to "mouse", and then "press F2" by using the action.actionPerformed... and... it works, in the sense that in my table cell renderer I allow only dates values or None, not strings, so an AssertionError is raised. Meaning that I have managed to simulate an F2 key press (NB although the name of this action is "startEditing", it also stops an editing session, in real life as in testing).
... I could content myself with using editCellAt, and having ascertained that F2 has the right entry in the right InputMap, and that the value is pops out is an Action (could be checked) with the name "startEditing", which is proven to be capable of ending an edit, I could just content myself with that.
But I so hate it when my understanding is revealed to be less than good! I want to know WHY this doesn't work...
Found the answer and put it here for reference.
My requestFocus() action on the JTable did indeed leave selection on the right row, but without any selection of the (single) column. Even when running as normal (not testing) the JTable column did not initially respond to F2. It was puzzling to me why the cell was not initially surrounded by a heavy black border. The answer was therefore to put this line after the requestFocus line:
dates_table.setColumnSelectionInterval( 0, 0 )
As a homework assignment, I'm writing a code that uses the bisection method to calculate the root of a function with one variable within a range. I created a user function that does the calculations, but one of the inputs of the function is supposed to be "fun" which is supposed to be set equal to the function.
Here is my code, before I go on:
function [ Ts ] = BisectionRoot( fun,a,b,TolMax )
%This function finds the value of Ts by finding the root of a given function within a given range to a given
%tolerance, using the Bisection Method.
Fa = fun(a);
Fb = fun(b);
if Fa * Fb > 0
disp('Error: The function has no roots in between the given bounds')
else
xNS = (a + b)/2;
toli = abs((b-a)/2);
FxNS = fun(xns);
if FxNS == 0
Ts = xNS;
break
end
if toli , TolMax
Ts = xNS;
break
end
if fun(a) * FxNS < 0
b = xNS;
else
a = xNS;
end
end
Ts
end
The input arguments are defined by our teacher, so I can't mess with them. We're supposed to set those variables in the command window before running the function. That way, we can use the program later on for other things. (Even though I think fzero() can be used to do this)
My problem is that I'm not sure how to set fun to something, and then use that in a way that I can do fun(a) or fun(b). In our book they do something they call defining f(x) as an anonymous function. They do this for an example problem:
F = # (x) 8-4.5*(x-sin(x))
But when I try doing that, I get the error, Error: Unexpected MATLAB operator.
If you guys want to try running the program to test your solutions before posting (hopefully my program works!) you can use these variables from an example in the book:
fun = 8 - 4.5*(x - sin(x))
a = 2
b = 3
TolMax = .001
The answer the get in the book for using those is 2.430664.
I'm sure the answer to this is incredibly easy and straightforward, but for some reason, I can't find a way to do it! Thank you for your help.
To get you going, it looks like your example is missing some syntax. Instead of either of these (from your question):
fun = 8 - 4.5*(x - sin(x)) % Missing function handle declaration symbol "#"
F = # (x) 8-4.5*(x-sin9(x)) %Unless you have defined it, there is no function "sin9"
Use
fun = #(x) 8 - 4.5*(x - sin(x))
Then you would call your function like this:
fun = #(x) 8 - 4.5*(x - sin(x));
a = 2;
b = 3;
TolMax = .001;
root = BisectionRoot( fun,a,b,TolMax );
To debug (which you will need to do), use the debugger.
The command dbstop if error stops execution and opens the file at the point of the problem, letting you examine the variable values and function stack.
Clicking on the "-" marks in the editor creates a break point, forcing the function to pause execution at that point, again so that you can examine the contents. Note that you can step through the code line by line using the debug buttons at the top of the editor.
dbquit quits debug mode
dbclear all clears all break points
