Shiny, I must try adding multiple parries myself.
Aye, it works just like with every other animation.
You have 3 different types for every animation. Let's take the parry against attacks from above for example.
You have an animation to hold (Player moves his weapon in defence)
An animation to keep (Player stays in this position)
And an animation for parry (The player moves his defence a bit, so it looks like the weapon was hit)
I've taken the third animation for my "active" parries. But as you may have noticed, the player moves a bit to late (when the enemy would already hit him).
I've looked for something to do the defence animation a bit earlier, but I have not found anything....
