Sprite sheets give me a headache

[richmond62]

They do, you know, because I am sick and tired of spending yonks chopping them up into individual
images to use as backGroundPatterns for a graphic . . .

I am looking for guidance (NO, not THAT kind of guidance) on how I might use a sprite sheet in its raw, unprocessed form
to animate inwith a grc 'frame.

NOT "cutting the mustard."

Well; here's a crappy solution that uses a grouped image, but presupposes that one knows
where the centre of each image inwith the
sprite image lies (which I don't: hence the crappy result).

At which point, I suppose, I could piss about, chopping up the sprite image
to reposition the sprites to predetermined locations
(one could do that with importing a folder of the chopped up images, grouping them
and then importing a snapshot from the group), which is almost as fun as
banging one's head on the wall, chopping up the sprite image into bits for
backGroundPatterns, or standing on one leg for 25 years.

You can use your favorite coding language to select the coordinates of each image and display them accordingly

Err, well, जै . . . I wonder how I can do THIS in my favOUrite coding language (erm: LiveCode)?

AND, if LiveCode could do that, I could just be lazy and get my sprite sheets from places like this:

This, of course, is totally beside the point

[although it is rocky that I found something that chops up sprite sheets quicker than I can cut open
my thumb with a penknife.]

as it does NOT answer my original questions (either of them).

Thank you very much Kangaroo SW:

1. Very clever.

2. No obvious benefit over using individual images

(just more complicated coding).

Richmond,

Thank you.

Very clever, very complicated and ALL for the sake of NOT chopping up a sprite sheet.

The effort, in my case at least, does not seem justified.

The effort, in my case at least, does not seem justified.

The main benefit as far as i can see is you're managing just 1 image instead of say 12 or 20. It does require extra effort in preparing the images to just one image, as all cells have to be the same size and all images have to be centred in that cell, but that's a 1-time job.

I'm not sure the output is any different/speedier, but when working with an app, managing just one image greatly simplifies things i suppose.

all cells have to be the same size and all images have to be centred in that cell

These both seem disadvantages as with a series of images of differing dimensions on displaying them
in a graphic as a backGroundPattern one can reset the graphic;s dimensions to take the image
dimensions into account.

have to be chopped up into individual images UNLESS jiml's Cel-animation
can be modded to change the dimensions of the group containing the sprite sheet for each frame.

As I am considering writing a leaflet not called "Making Side Scrolling Games for Morons", that is the title
I will be repeating under my breath.

Your Warrior sprite doesn't need to change size for each sprite.

You can make SpriteSheets with ImageMagick
or cut it into pieces

The active part of that sprite is the sword
Is enemy character within the rect of the sprite container? Is sword attack animation active? Take damage.
Is enemy character within the rect of the sprite container? Are they left of the center? Are they attacking? Warrior dies!

I did that years ago and not to avoid chopping a sprite sheet but to get blindingly fast animation in LiveCode.
You're welcome!

[richmond62]

to get blindingly fast animation

Ah, I understand, but, nothing I ever do is blindingly fast.

One Size to Rule them all

Not always!
