tkinter: How to make timer run in a background-CodePudding

I have a game - catching coins into a bowl. However, one of the criteria is to make it limited by entering time in seconds - how long will the game last. The time user enters is from tkinter.Entry, and I have no idea how to execute a timer and a function at the same time. Code progress:

import tkinter, random, time
from threading import Thread

window = tkinter.Tk()
window.title("Dukaty")

canvas = tkinter.Canvas(window, height = 400, width = 800)
canvas.pack()


timeLabel = tkinter.Label(text = "Time:", font = "Helvetica 15")
timeLabel.pack()
timeEntry = tkinter.Entry(bd = 1)
timeEntry.pack()
mistakesLabel = tkinter.Label(text = "Allowed mistakes:", font = "Helvetica 15")
mistakesLabel.pack()
mistakesEntry = tkinter.Entry(bd = 1)
mistakesEntry.pack()

timeEntry.insert(0, "0")
mistakesEntry.insert(0, "0")

speed = 250
score = 0
mistakes = 0
allowedTime = ""


def countdown(t):
    while t:
        mins, secs = divmod(t, 60)
        timer = '{:02d}:{:02d}'.format(mins, secs)
        allowedTime = timer
        print(allowedTime)
        time.sleep(1)
        t -= 1

    print("Time's up!")


def timedGame():
    time = int(timeEntry.get())
    canvas.after(time * 1000)
    end()

def movingCoin():
    global speed, score, mistakes, allowedTime
    time = int(timeEntry.get())
    coin = canvas.create_image(random.randint(15, 585), 18, image=coinImg, tags="coin")

    canvas.create_text(700, 50, text = str(score), font = "Helvetica 20", fill = "green", tags = "score")
    canvas.create_text(700, 80, text = str(mistakes), font = "Helvetica 20", fill = "red", tags = "mistakes")
    # ENDLESS

    if timeEntry.get() == "0" and mistakesEntry.get() == "0":
        while True:
            if canvas.coords(coin)[1] < 360:
                canvas.move(coin, 0, 5)
                canvas.after(speed)
                canvas.update()
            elif canvas.coords(coin)[1] >= 360 and (canvas.coords(coin)[0] > (canvas.coords(bowl)[0] - 40) and canvas.coords(coin)[0] < (canvas.coords(bowl)[0]   40)):
                canvas.delete("score")
                score  = 1
                canvas.create_text(700, 50, text=str(score), font="Helvetica 20", fill="green", tags="score")
                canvas.delete(coin)
                coin = canvas.create_image(random.randint(15, 585), 18, image=coinImg, tags="coin")
                speed -= 10
            else:
                canvas.delete("mistakes")
                mistakes  = 1
                canvas.create_text(700, 80, text=str(mistakes), font="Helvetica 20", fill="red", tags="mistakes")
                canvas.delete(coin)
                coin = canvas.create_image(random.randint(15, 585), 18, image=coinImg, tags="coin")
                speed -= 10

    # TIME - not done yet

    elif timeEntry.get() != "0" and mistakesEntry.get() == "0":
        while str(allowedTime) != "00:00":
            if canvas.coords(coin)[1] < 360:
                canvas.move(coin, 0, 5)
                canvas.after(speed)
                canvas.update()
            elif canvas.coords(coin)[1] >= 360 and (canvas.coords(coin)[0] > (canvas.coords(bowl)[0] - 40) and canvas.coords(coin)[0] < (canvas.coords(bowl)[0]   40)):
                score  = 1
                print(score)
                canvas.delete(coin)
                coin = canvas.create_image(random.randint(15, 585), 18, image=coinImg, tags="coin")
                speed -= 10
            else:
                mistakes  = 1
                print(mistakes)
                canvas.delete(coin)
                coin = canvas.create_image(random.randint(15, 585), 18, image=coinImg, tags="coin")
                speed -= 10



    # MISTAKES

    elif timeEntry.get() == "0" and mistakesEntry != "0":

        allowedMistakes = int(mistakesEntry.get())
        print("Allowed mistakes: "   str(allowedMistakes))

        while True:
            if canvas.coords(coin)[1] < 360:
                canvas.move(coin, 0, 5)
                canvas.after(speed)
                canvas.update()
            elif canvas.coords(coin)[1] >= 360 and (canvas.coords(coin)[0] > (canvas.coords(bowl)[0] - 40) and canvas.coords(coin)[0] < (canvas.coords(bowl)[0]   40)):
                canvas.delete("score")
                score  = 1
                canvas.create_text(700, 50, text=str(score), font="Helvetica 20", fill="green", tags="score")
                canvas.delete(coin)
                coin = canvas.create_image(random.randint(15, 585), 18, image=coinImg, tags="coin")
                speed -= 10
            else:
                if allowedMistakes > mistakes:
                    canvas.delete("mistakes")
                    mistakes  = 1
                    canvas.create_text(700, 80, text=str(mistakes), font="Helvetica 20", fill="red", tags="mistakes")
                    canvas.delete(coin)
                    coin = canvas.create_image(random.randint(15, 585), 18, image=coinImg, tags="coin")
                    speed -= 10

                elif allowedMistakes == mistakes:
                    print("ending the program")
                    break


def end():
    window.destroy()

def tap():
    Thread(target=countdown(int(timeEntry.get()))).start()
    Thread(target=movingCoin).start()

endButton = tkinter.Button(text = "End", command = end)
endButton.pack(side = "right")
startButton = tkinter.Button(text = "Start", command = tap)
startButton.pack(side = "left")


window.mainloop()

What this does, is that it starts the timer, and when it comes to end, THEN it executes the movingCoin function.

What I want to achieve is to make the timer start (when in Entry is value greater than 0) and at the same time execute the movingCoin - which then drops to the time section and the while breaks when the time is up.

CodePudding user response：

You can use this method

window.after(1000,<function_name>)

It means the function call after 1 sec. If you are use recursion with this method then you can create timer.

I hope it works for you, cheer.

import time
# time.time() return in second
game_duration = float(input('duration: '))   time.time() 

game_is_running = True

while game_is_running:
    if game_duration == time.time(): # this means: if now equal to game_duration
        game_is_running = False
