Symptom

Bug.1
If you press the attack key just before the normal attack motion ends, 
it will lock in place and attack without moving forward.

Bug.2
If you press the attack key consecutively after using power attack, 
it will lock in place and repeat the same power attack.

                                                                                                                     

Solution

Bug.1 completely modified it by increasing the attack key input timing.

Bug.2, if you press the attack key while using power attack, it will naturally lead to normal attack again after using power attack.
The subsequent normal attack starts again from the first combo.

                                                                                                                     

AND

This fix solves all of the above bugs, but the movement is limited until the attack animation is all over.
Now, like in the soul game, you have to be more careful with your attacks,
and you need to cancel the delay with Dodge or Guard depending on the situation for the subsequent delay after the attack.


                                                                                                                     


Only the animation files of the skysa main mode were uploaded for editing,

How to fix it yourself is explained below,

If we take a look at the contents of SKYSA animation event before fix

  # duration: 2.333333 // total animation length
  0.233333 SkySA_TriggerIntervalWin // Start detecting attack key input
  0.400000 CastOKStart
  0.500000 preHitFrame
  0.633333 weaponSwing
  0.733333 HitFrame
  0.933333 SkySA_AttackWinStart // If an attack key is input, the starting point of moving to the next combo motion
  1.166667 SkySA_AttackWinEnd // End of detection of attack key input
  2.300000 attackStop // end animation
 
If the attack key is entered after detection of the attack key input is completed,
It is designed to start the combo again from the beginning without continuing to the next combo.
However, if an attack key is entered between SkySA_AttackWinEnd and attackStop, as shown in the video
Fixed in place and wielding bug occurs.
 
You must enter the attack key after attackStop, but it leads to the first combo properly.
So, simply modify SkySA_AttackWinEnd to be 1 frame longer than attackStop.

actually
Since the motion from SkySA_AttackWinStart to SkySA_AttackWinEnd is the motion of the next combo start point,
we set a section that continues as naturally as possible,but I think that if it is accompanied by a fatal bug,
the meaning becomes meaningless.
 
If you modify it as above, you will never see the floundering movement in place again.

In Power Attack, add a Loop annotation and

You can modify SkySA_AttackWinEnd to be 1 frame longer than attackStop.

If you modify it as above, if you enter the attack key while using Power Attack,

In the section specified by SkySA_AttackLoop and SkySA_AttackWinEnd,

the normal attack continues smoothly and the combo is performed again from the beginning.
