Renpy "sprites"?

[Errilhl]

Okay, I'm a little bit confused about Renpy and sprites - both the naming, and the usage.

First - does Renpy refer to any image as a "sprite"?
While that is acceptable, coming from a web-design background, that is confusing, since a sprite is a collection of images put into one larger image, and then used by defining a position on that image to show.

Second - if Renpy uses "image" and "sprite" as synonyms, is there a way to define a "CSS sprite"? Or should I just have separate sprites (images) for each and every emotion and the like? (Seems that that can quickly become a lot of images, but sure)

If it is possible to have a "CSS sprite" functionality, how would one define / use that?

Dictionary.com - an icon in a computer game which can be manoeuvred around the screen by means of a joystick, etc
Google Meaning - a computer graphic which may be moved on-screen and otherwise manipulated as a single entity.

Both seem to indicate Sprite as the same as how Ren'py uses the term, basically all the images that are not scene backgrounds, buttons, frames, gui etc.

I would say a collection of images gathered as a single image where the parts are cropped out as needed is more commonly termed a sprite-sheet and though Ren'py does not have an in-built sprite-sheet reader it should not be too tricky to run one up.
I would suggest using the common XML format like Leshy uses, read that using ElementTree ( import xml.etree.ElementTree as etree sort of approach ) and crop/render using an approach similar to the legacy FilmStrip method ( renpy\display\anim.py line 570 ish ) or LiveCrop() to create images ( as simple as ... sprite = LiveCrop( ( x, y, w, h ), "sprites/sprite_sheet.png" ) ... )

Not dabbled with CSS in many years. so I am not familiar with how it uses Sprites... hopefully the above info is useful though.

Okay, thanks Oh, I will probably not get into that (trying to make a sheet, so to speak) - I was just wondering, because the term (to me) is a bit confusing, especially since it mucks about with both images and sprites a little haphazardly. But that's good to know, then I will just have to create separate images, basically

In web terminology, you would actually call what you described as a "sprite", a "spritesheet"

Regarding having one image for each emotion, you can save yourself a lot of file size, by using live composite

I haven't used this function, so am not sure what its actually called.
