I understand that there is no such thing as priority in SFIV, and it’s all about when/where active frames of attacks are, when/where vulnerable hitboxes are, plus whether or not someone had invincibility frames.
With that said, why am I able to randomly, CLEANLY poke (i.e not a trade) a boxer spamming crouching light punches with…say… Claw’s crouching medium punch some times, but get beat or traded by Boxer most of the other times?
I assume that Boxer’s vulnerable hit box is where it should logically be throughout his attack (i.e. anywhere but his fist) and I assume Claw’s active hit box during the active frames of his attack are where it logically should be too (just his claw).
Boxer’s crouching jab has 2 frames of startup, 2 active frames, and 5 recovery frames.
So a Boxer’s spamming jab looks like this:
frame 1: startup
frame 2: startup
frame 3: hit
frame 4: hit
frame 5: recovery
frame 6: recovery
frame 7: recovery
frame 8: recovery
frame 9: recovery
frame 10: startup
frame 11: startup
frame 12: hit
frame 13: hit
frame 14: recovery
frame 15: recovery
frame 16: recovery
frame 17: recovery
frame 18: recovery
frame 19: startup
etc. etc.
Claw’s crouching medium punch becomes active on frame 4. So am I simply getting lucky and starting up Claw’s crouching medium punch out of Boxer’s reach and/or during Boxer’s recovery frames and hitting Boxer during the Boxer’s startup/recovery frames?
If Claw is OUTSIDE the boxer’s range, then Claw is safe on the startup and recovery frames of his cr. medium punch and Claw is able to hit him on 7 out of 9 frames (Boxer’s 2 + 5 frames of startup and recovery).
So looking at a repeatedly jabbing Boxer, let’s look at just two jabs back-to-back which is 18 frames. If Claw is JUST INSIDE Boxer’s hitting range (i.e. if Claw is close enough so that he would be vulnerable to a hit during his startup animation) I can only start up Claw’s jab on frames 5, 6, 7, 8 to cleanly hit boxer with it. So I only have a 4/18 chance of beating him. So can I say that Claw’s cr. medium punch only has a 2/9 chance of cleanly beating Boxer’s jab spamming if Claw is JUST WITHIN the Boxer’s hitting range?
If Boxer and Claw are RIGHT NEXT to each other, any repeated non-comboing, non-knockdown attack pushes two players away from each other on hit or block so we don’t look at repeated jabbing, we look at just a single usage of each attack… Boxer’s cr. light punch always beats Claw’s cr. medium punch, since Boxer’s attack comes out at 3 frames, while Claw’s comes out in 4.
