If what you want if to juggle with every move after her throw, then you need to remove this:
[State 1466, Juggle]
type=varadd
trigger1= numtarget && !time
var(15)=1
ignorehitpause=1
[State 1466, Juggle]
type=varset
trigger1= numtarget && !time
var(16)=1
ignorehitpause=1
and add this
[State xxx, Juggle Reset]
type = VarSet
trigger1 = CONDITION
var(15) = 0
with condition being the animelem when kotaro throws the opponent. I'll try to explain the reason why so you just don't learn how to do stuff but you learn why you do stuff.
most moves have a hitdef with a trigger like this one:
triggerAll = !var(16) && (var(15) < 1 || var(20))
Let's break it down. This trigger means:
when var(16) is 0
AND
when var(15) is less than 1 OR when there's var(20) on
what are these three vars?
var(16) is a juggle flag. If it's set to 1, you can't combo anymore, because most hitdefs have !var(16), remember?
Your other throw had it so you couldn't combo off throw.
var(15) is the juggle points flag. var(15) basically increases by 1 every time you hit and put p2 into a falling state (a knockdown). Most moves (all normals notably) have var(15) < 1, so if you hit a character with anything that knockdowns, you will not be able to hit P2 again, because var(15) needs to be less than 1, remember?
you had a varAdd on the throw so you couldn't combo off throw
var(20) is the custom combo flag. when custom combo is on, var(20) is on. Remember that it was either var(15) < 1 OR var(20)? this is because when Custom Combo is on, you can ALWAYS juggle.
Now, let's go back to what we made.
we removed this
[State 1466, Juggle]
type=varadd
trigger1= numtarget && !time
var(15)=1
ignorehitpause=1
[State 1466, Juggle]
type=varset
trigger1= numtarget && !time
var(16)=1
ignorehitpause=1
this way var(16) is not 1 and var(15) doesn't add 1, hence your hitdefs will me their triggers, right?
triggerAll = !var(16) && (var(15) < 1 || var(20))
and then we added this:
[State xxx, Juggle Reset]
type = VarSet
trigger1 = CONDITION
var(15) = 0
this way var(15) is ALWAYS 0, so the var(15) < 1 condition of the hitdef is ALWAYS met, see?
I hope I was clear. Ask without holding back.
