That looks quite good, do you have learning materials you’d recommend? It has been on my todo list for a year, but it looks like such a monumental effort :x

What other language reverses arguments when doing partial application?

It should not warn, it should apologize 😂

5. Add a script with:

- The `@export value` you'll use to set your new progress bar,
- An update function that shifts the atlas' region based on the value.

I just let the script do the maths for me, no other input than the atlas itself.

4. Pick the correct region size:

h is the total height
w is the total width divided by the number of frames

You can quickly find these values by looking at Godot's UI. It'll also do the math for you (input 520 / 5).

I'm short on time, so I just repurposed Godot's Atlases:

1. Create a sprite in asesprite, each frame is a step
2. Export it as a single sprite sheet.
3. Import as an Atlas
