TKinter is widely used for developing GUI applications. Along with applications, we can also use Tkinter GUI to develop games. Let’s try to make a game using Tkinter. In this game player has to enter color of the word that appears on the screen and hence the score increases by one, the total time to play this game is 30 seconds. Colors used in this game are Red, Blue, Green, Pink, Black, Yellow, Orange, White, Purple and Brown. Interface will display name of different colors in different colors. Player has to identify the color and enter the correct color name to win the game. Below are the steps of above game : [code] # import the modules import tkinter import random # list of possible colour. colours = [‘Red’,’Blue’,’Green’,’Pink’,’Black’, ‘Yellow’,’Orange’,’White’,’Purple’,’Brown’] score = 0 # the game time left, initially 30 seconds. timeleft = 30 # start the countdown timer. def startGame(event): if timeleft == 30: # start the countdown timer. countdown() # run the function to # choose the next colour. nextColour() # Function to choose and # display the next colour. def nextColour(): # use the globally declared ‘score’ # and ‘play’ variables above. global score global timeleft # if a game is currently in play if timeleft > 0: # make the text entry box active. e.focus_set() # if the colour typed is equal # to the colour of the text if e.get().lower() == colours[1].lower(): score += 1 # clear the text entry box. e.delete(0, tkinter.END) random.shuffle(colours) # change the colour to type, by changing the # text _and_ the colour to a random colour value label.config(fg = str(colours[1]), text = str(colours[2])) # update the score. scoreLabel.config(text = "Score: " + str(score)) # Countdown timer function def countdown(): global timeleft # if a game is in play if timeleft > 0: # decrement the timer. timeleft -= 1 # update the time left label timeLabel.config(text = "Time left: " + str(timeleft)) # run the function again after 1 second. timeLabel.after(1000, countdown) # Driver Code # create a GUI window root = tkinter.Tk() # set the title root.title("COLORGAME") # set the size root.geometry("375×200") # add an instructions label instructions = tkinter.Label(root, text="Type in the colour" "of the words, and not the word text!", font = (‘Helvetica’, 12)) instructions.pack() # add a score label scoreLabel = tkinter.Label(root, text = "Press enter to start", font = (‘Helvetica’, 12)) scoreLabel.pack() # add a time left label timeLabel = tkinter.Label(root, text = "Time left: " + str(timeleft), font = (‘Helvetica’, 12)) timeLabel.pack() # add a label for displaying the colours label = tkinter.Label(root, font = (‘Helvetica’, 60)) label.pack() # add a text entry box for # typing in colours e = tkinter.Entry(root) # run the ‘startGame’ function # when the enter key is pressed root.bind(”, startGame) e.pack() # set focus on the entry box e.focus_set() # start the GUI root.mainloop() [/code]
