Is it possible to post here the URL where you got this gif?

I also tried this one: http://bestanimations.com/Animals/Mammals/Horses/horse-walking-animated-gif1.gif

Very simple, trotting horses. Not much memory space.

Downloaded it, then imported in Pythonista (+, import photo, no need to use a Photos script ) and quick look shows the movement.

1: Thanks for that, @cvp. I didn't even know that was there. How stupid of me; I have used Pythonista for several years now, and have never used anything in that menu except for add script, pyui file, and txt file.

2: It returns an IOError when I try to make a SpriteNode out of it. What now?

NoBetterName

Hold on, made some adjustments...
It now produces a still image with no animation as a SpriteNode.

@NoBetterName Sorry, I've never used scene....I can't help you more.

@JonB Missing import.os and w.present

@NoBetterName Since we don't have either your code, or a full traceback, how can we possibly help debug your code! Paste a minimal example that shows the issue, (using three backticks to format code), and paste a full traceback.

Are you using the GifSpriteNode git?

Oh, sorry about that. Right now, I'm just trying to fix a simplified, very basic, gif-SpriteNode thing-a-ma-bobby. This is my code:

from scene import *

class MyScene(Scene):
	def setup(self):
		img = 'horsegif.GIF'
		texture = Texture(img)
		background = SpriteNode(texture)
		background.size = self.size
		background.anchor_point = 0,0
		background.position = 0,0
		self.add_child(background)
		
run(MyScene())

It isnt much.

By that way, the adjustment that I made earlier was just making the Texture from a file path instead of a ui.Image of the gif file. I don't know why it changed the results... I'm a bit clueless when it comes to gifs.

Perhaps, I say perhaps because I really don't know anything about scene, you could use image2gif to extract an array of PIL images (via readGif) and display each frame when scene runs....

cvp

You could also extract frames of your gif online, by example here and download a zip with all the frames, and then process it locally

Problem with that, scene runs 60 times per second. Way too fast. I used the example above to process a gif and add it to a scene. Thanks @ccc!
I devised a switch system to slow down a gif if it goes too fast, as it seems that the gif @ccc referred to did something similar to your idea, @cvp. Thanks for all the help guys, and hopefully you will see this app on the App Store sometime soon!

get_horse.py...

import console, requests

url = 'http://bestanimations.com/Animals/Mammals/Horses/horse-walking-animated-gif1.gif'
# url = 'http://fc00.deviantart.net/fs71/f/2012/189/a/a/dressage_horse_animation_by_lauwiie1993-d56it04.gif'
filename = url.split('/')[-1]

with open(filename, 'wb') as out_file:
    out_file.write(requests.get(url).content)
console.quicklook(filename)

I tried to remove as many class attributes from GifSpriteNode as possible to simplify/streamline the class. Perhaps a bit too radical. ;-) The duration is now hard coded because I did not find the gif.info['duration'] values to be very helpful. The commented URL seems to have a palette issue on one frame.
