Tails Flying Code v3

	move.b	#AniIDTailsAni_Fly,anim(a0)	; begin flying
	move.b	#$4B,flight_time(a0)		; set the amount of time Tails can fly for (this is needed later, in Tails_FlyingSwimming)
	move.w	#$C,y_vel(a0)			; set Tails' y-velocity to something reasonable (again, needed later, in Tails_FlyingSwimming)
	bset	#1,flight_property(a0)		; tell the game that Tails is flying (part 1)
