Play an Animated GIF in python with tkinter

I am wanting to create a virtual pet style game using python3 and tkinter. So far I have the main window and have started putting labels in, but the issue I am having is playing an animated gif. I have searched on here and have found some answers, but they keep throwing errors. The result I found has the index position of the gif using PhotoImage continue through a certain range.

    # Loop through the index of the animated gif
frame2 = [PhotoImage(file='images/ball-1.gif', format = 'gif -index %i' %i) for i in range(100)]

def update(ind):

    frame = frame2[ind]
    ind += 1
    img.configure(image=frame)
    ms.after(100, update, ind)

img = Label(ms)
img.place(x=250, y=250, anchor="center")

ms.after(0, update, 0)
ms.mainloop()

When I run this in terminal with "pyhton3 main.py" I get the following error:

_tkinter.TclError: no image data for this index

What am I overlooking or completely leaving out?

Here is the link to the GitHub repository to see the full project:VirtPet_Python

Thanks in advance!

Solution 1:

The error means that you tried to load 100 frames, but the gif has less than that.

Animated gifs in tkinter are notoriously bad. I wrote this code an age ago that you can steal from, but will get laggy with anything but small gifs:

import tkinter as tk
from PIL import Image, ImageTk
from itertools import count

class ImageLabel(tk.Label):
    """a label that displays images, and plays them if they are gifs"""
    def load(self, im):
        if isinstance(im, str):
            im = Image.open(im)
        self.loc = 0
        self.frames = []

        try:
            for i in count(1):
                self.frames.append(ImageTk.PhotoImage(im.copy()))
                im.seek(i)
        except EOFError:
            pass

        try:
            self.delay = im.info['duration']
        except:
            self.delay = 100

        if len(self.frames) == 1:
            self.config(image=self.frames[0])
        else:
            self.next_frame()

    def unload(self):
        self.config(image="")
        self.frames = None

    def next_frame(self):
        if self.frames:
            self.loc += 1
            self.loc %= len(self.frames)
            self.config(image=self.frames[self.loc])
            self.after(self.delay, self.next_frame)

root = tk.Tk()
lbl = ImageLabel(root)
lbl.pack()
lbl.load('ball-1.gif')
root.mainloop()

Solution 2:

First of all, you need to know what is the last range of your GIF file. so by changing the different value of i, you will get it.For my condition is 31. then just need to put the condition.So it will play gif infinitely.

    from tkinter import *
    import time
    import os
    root = Tk()

    frames = [PhotoImage(file='./images/play.gif',format = 'gif -index %i' %(i)) for i in range(31)]

    def update(ind):
        frame = frames[ind]
        ind += 1
        print(ind)
        if ind>30: #With this condition it will play gif infinitely
            ind = 0
        label.configure(image=frame)
        root.after(100, update, ind)

    label = Label(root)
    label.pack()
    root.after(0, update, 0)
    root.mainloop()
