AntiKnockback not cancel kb if kb is in the direction of moving

HydroHimself

so today I had a idea. antikb will work as normal but if you use this setting then it will still work normal accept one thing, if you are moving forward and someone hit you in the back, then anti kb won't cancel that kb, so it will be like a boost. but if someone hits you from front then it will remove kb like normal it works. same thing with move backward and et cetera

HydroHimself sounds quite interesting!
what should be done tho, if the hit diesnt come from straight from behind, but with an 30° Offset?
I can imagine multiple things (changable in settings):

Make a slider (0° to 90°) how much offset is allowed from the kb of the hit in comparison to movement, so that it will not cancel kb
split the hit-kb vector in one that is linear dependent to the player movement and one orthogonal to it. discard the second vector, and check if the first one is in the same direction as the üplayer, and if yes it should be allowed.
using this method guarantees that the player will continue to move forward.
