Maybe I asked my questions in a way that wasn't entirely clear. To put into context, I have modded the games aircraft art before the ability to have rotating aircraft art was possible. So I know how to add to the 'film strip' for each side.
My real question is can you add more aircraft than the film strip method would allow by utilizing the single aircraft sides described in the the art mod thread? IE add in airplane art like you would ship sides. My problem is that I want to add in more aircraft for the Axis side than I have film strip slots available.
I'm running out of slots for planes, so my real question is there a hard limit on the number of unique plane sides (not counting rotating art per year) that I can add to the game?
You can easily add more aircraft (called slots in the aircraft file) than there are art bitmaps -
and I think everyone does that to some degree - including stock. However, you may not increase
the number of bitmaps. The trick is to learn how to share bitmaps. DIFFERENT but similar planes
may point at the SAME bitmap! In my view, there also are many cases of "nearly duplicated" art -
I sometimes go with fewer Zeros (or whatever) in different colors - in favor of freeing up bitmaps
for completely different types of aircraft. That is one way to "cheat" and get "more" bitmaps -
share virtually identical types more.
Note that the Allies cannot use the very bottom right bitmap (500) - for whatever reason code does
not allow us to point at it.
Your proposal will not work in general but might in a carefully organized case. Once you change
the art - it will no longer be available in its original form. But if you "know" some plane is
going to "disappear" (and there are a tiny number of such cases) you could "modify" the bitmap
for a later aircraft - and that might be a way to add another bitmap to the set. Mifune has
some concern that rotating art is a potential source of errors that might crash the game -
bitmaps can do that - so after considering it I have decided not to use it. But IF you run
out of bitmaps a very few cases might be possible to arrange if you date separate the selected
types. You would have to coordinate the substitute art to include a side, a top and an alpha all
at the same time if you were changing the art completely.
