FLI explained, please...

Hola,

I'm looking for an easy-understandable-for-a-novice description, preferably with a *documented* example to go along with it, of how FLI actually works, including a description of how the colordata is stored (so i'll know how to manipulate it). My C64 skills are very novice/rusty indeed, so the more documentation, the better...

I have already been searching this forum and the C64 codebase for the sorts, but found what seems like a trillion different FLI formats (FLI, AFLI, XFLI, IFLI, MUFLI, etc) with different resolutions... But, I'm merely thinking of "normal fli" (if there is such a thing) capable of handling a width of 40 chars (and at least a height of 10 chars), no sprites involved, and 16 colours per char, running as part of the normal IRQ. Make sense?

Furthermore, a reference to a drawing-program that can save in the explained format, or at least in a format that can be converted into it, would be very nice!

That's not much to ask for, is it? :)

Any help will be greatly appreciated...!

Regards /Dragnet

Hola,

Well, I thought the FLI bug had been fixed years ago, cause I seem to remember several demos using what to me seemed like 40 chars of FLI (last I used FLI, merely as a fixed image, was in 1993 using Black Mails old editor, I think... :) ). That's way I asked for 40 chars, but must have been cleverly designed images or just me not understanding what I was looking at... 37 chars will do just fine for me; well, actually 34 to make it nice and symetrical! :)

Anyways - thanks for the replies, and especially the link to the explanation, MagerValp! Would still like some actual documented code examples, though. The discussion here quickly turned way too technical for me - I guess there is no way around me doing some serious homework regarding the technical side of the beloved breadbox!

There is some stuff on codebase on FLI:

Maybe of interest for you?

Atleast every 8th rasterline of an FLI picture can have full 40 chars width. And then you can always use the FLI-bug colors + sprites + rasterbars to make the bug area more useful.

If the picture is designed with the limitations of the FLI bug area in mind, the casual viewer will not know that it's there. The undisputed master of this is Mirage:

Oh Noes, They Be Stealing My Bench
Ms. Pac Man
Fundamentals of Icosahedral Symmetry
Donkey Kong -1LIFE/PAL
Space Invaders

...so how do you get Timanthes to save FLI bug colors?

By pressing 'save'

...I think he meant "in what format is the FLI bug colour stored inside the file" :-)
No he doesn't...

I don't remember seeing that in the Export As dialog, and I can't test it as Timanthes has decided to crash every damn time I click save or export...

Mirage uploaded a more recent executable not so long ago. Tried that?

The executable is date stamped 2009-02-20, and the About box says Final Debug Build 3.0.3338.37500. I think that's the latest.

Yup, it is.
