if I'm not mistaken, I can only do a successful deflect if the enemies poise is drained. that's why I can do a successful auto-deflect on a boss second chain attack but not the first one:
the first auto-deflect would drain the boss' poise, and when the second auto-deflect happens at the boss second chain attack, his poise is down already, and the deflect would break his guard, so a successful deflect would occur.
it's the same as the easy guard break script, 1st attack on a guarding enemy would drain his poise, second on a guarding enemy would break his guard.
so, my question is, did you try to deflect a boss attack without the script? I'm thinking, for the vanilla game, even if I do a good timed deflect on a boss attack, the boss still won't open for my deathblow until I've drained his poise...
I just killed the test subject by accident and a rest won't revive this mini-boss, so I can't test it again right away...
did you try the easy guard break
script, could it be the option you're looking for..?
done some tracing, although I've located and can manipulate both the speed, and the analogue input, it seems the game only have walk and run (and sprint) animations, without the transition. form around 0.2 to 0.8 speed the game would use the walk animation (at a fixed slow speed), and from around 0.9x on the game would use the run animation (again, at a fix speed).
maybe I just haven't locate the proper value yet~ but I'm done with it for now...
did you try the link 2 post above yours? viewtopic.php?f=4&t=8938&start=105#p83339
maybe it'd help.
