Make flight spells cost zero if the target can already fly

[beholderface]

Because I made a wisp capable of applying Anchorite's Flight on a regular basis, then realized that it would just be wasting media most of the time.
IMO the ideal solution to this would be to make the flight spells overwrite flight abilities applied by hex (but not any others), but I don't know how one would do that.

[object-Object]

uh, wouldn't this just make it free to infinitely move Anchorite's around with you forever? that seems a bit broken

[beholderface]

No, because it still doesn't overwrite any existing flight, and as such you'd need to exit the flight radius before it would do anything, thus making it have nonzero cost.

honestly I feel like this could apply... but only to wayfarers
so that you could eg: deploy anchorites anywhere (and it is on you if they overlap (space or time wise)

[walksanatora]

that or mabey instead of making it zero it would add time to existing wayfarers flight? (or mabey set time to that and not consume the whole ammount of media for time remaining?)

Mostly just reviewed based on code style. I'm still not 100% sure I like this solution though. It feels weird from a UX perspective to just silently fail (whether it takes any media or not).

If we want to make it overwrite an existing flight instead of setting the cost to 0 and silently failing, we could instead change this condition:

HexMod/Common/src/main/java/at/petrak/hexcasting/common/casting/actions/spells/OpFlight.kt

Lines 69 to 73 in f1b0e89

	if (target.abilities.mayfly) {
	// Don't accidentally clobber someone else's flight
	// TODO make this a mishap?
	return
	}

to something like this:

  if (target.abilities.mayfly && IXplatAbstractions.INSTANCE.getFlight() == null) { 
     // Don't accidentally clobber someone else's non-Hex flight 
     // TODO make this a mishap? 
     return 
 }

I've dealt with the tweaks suggested in object's review, I haven't yet done anything to do with overriding flight since it's still under discussion

[gamma-delta]

I'd throw a mishap.

I think we decided on Discord that a good way to fix this would be to make both flight patterns mishap if the target can already fly, and also make a pattern to check if an entity can currently fly.
