Fluid Animation in current version of Renpy

[stormkwick]

I was looking up how to get fluid animated sprites working in Renpy and the posts that came up in my search were saying that there was no support beyond puppet animation, but all these posts i found were 5+ years old. I was wondering if anything has changed since. I know gifs still dont animate by default but is there any work around?

You can use ATL ( https://www.renpy.org/doc/html/atl.html ) to create animated images:

Code: Select all

image animated_image:
    "frame1.png"
    0.2
    "frame2.png"
    0.2
    "frame3.png"
    0.2
    repeat

Ren'py basically has the lower level facilities in place to show sets of images in sequence, just there is no extensive framework to handle each possible scenario.

As Ocelot mentions, you could simply use ATL though there are other options:
DynamicDisplayable => basically passes the time-base to a python function that returns an image to use for that particular time
LiveComposite => a displayable that layers other images into a single composite
Transforms => zoom, rotate, flip, move, alter alpha etc etc
As each can accommodate the others, the possibilities become endless. For example, you could have a LiveComposite that included an animated DynamicDisplayable part and other parts that rotated or morphed (doll-like), you'd just need to code it to suit.

Some people have taken things further, like here which uses OpenGL so there might even be options to hijack the libgdx or other runtime library of Spine to add full skeleton animation... (note truly sure of which render base Ren'py uses across platforms though, so anything along those lines would need some pre-sleuthing)

This is actually the first time I see this function documented in a human-readable way. Thank you!

You should to this for more of the cryptic functions many people don't dare use because they look like witchcraft.

Truth is that almost everything related to animation in Renpy is not well documented. ATL is awesome, but when you need to do things by hand with Python is when you start to suffer with the documentation.

One Night Stand has great animation and I think it is just done with ATL. You can check out the game to see what can be done in Ren'Py
