Interesting notes on Enemy skills, I was not aware it meant "everyone jump" I did try that a long time ago as a test on an Eagle and when they jumped they all came back down into the shape of Odin, bizarrely enough.
That's weird. Maybe it has something to do with the graphic change that's assumed with Jump (and nonexistent for monsters)?
Yes, the game only takes basic animations into account while fighting characters and those animations are Attack (with the DeathBringer graphic, at All Times) and Special Graphic, used by Kain, Dark Knight, and Yang.
What about Girl?
Does Rydia "cast" the Titan spell? I would assume not, but I don't remember. I don't even remember if she uses the Special Graphic or if Titan just appears. But it seems like it would be really odd if she just stood there the whole time...
For a long time I've been considering an Ancient Cave-esque hack for FFIV but... FFIV's system is nowhere near as robust as FFV's wonderful setup as far as the game flow goes. FFV has 23 Job Classes, and 110 learnable spells, with over 40 commands, many innate skills (of which 1 exists in FFIV, Auto-Hide) and formulaic setups for various weapon types, where in comparison FFIV has 13 Job Classes, 72 Learnable spells, and 26 Commands.
Therefore creating a randomizer or an Ancient Cave hack is much more difficult in the long run as far as balancing matters go.
I think this could be a fun project. I remember you mentioning this maybe a year or so ago. Knowing what I know about the game's coding now, I think I could help with the actual randomization if you wanted to be in charge of the mostly-everything-else.
I've been trying to devise some way to randomize monsters' attacks - not formally, really, just occasionally giving thought to how such a thing would work within the game's battle script system. I haven't had any major breakthroughs on that front... But I think randomizing treasures and rooms within a dungeon would be doable. Even randomizing which battles occur, but within a balanced structure, shouldn't be too tough.
I don't know if I've mentioned this yet, but in the current WIP of A Threat from Within, I've worked out a "different battle sets depending on terrain (on the world map)" system that could be used to inform the basis of a "controlled semi-random encounters (I can't think of a better way to write that)" system.
Anyway, we both obviously have our own projects we're working on now, and I don't want to bite off more than I can vhew, but this sounds like a fun idea to kick around.
