It's like you changed the "falling" style of jimmy when being punched by that attacks.
Yes... let me explain you a little more...
in fightingStyles like(Example) P_Striker_A u will find "Heavy Attacks", "RisingAttacks", "Charged Attacks, "LightAttacks" etc...
the rising Attack is the Finishing Cross punch...(the final punch on the combination set)
the Heavy Attack is the Uppercut...
the light attacks are all the evades..
well, those are the attacks that can make jimmy fly on the eter(xD)[exept the light ones.. i put it so u can have a better idea]
so i changed those.. so now the Straigth Cross got the finishing Cross Efect...
and the evadeback punch got the uppercut efect..
BUT those punch(finishing Cross and uppercut) didn't lost his effect!
i'm a Pro on Acts :')
