Its a bit of a well kept secret among developers it seems to me…If everyone knew how to do this then it seems that good fighting games would be “too easy” to make, and it would kind of be like inflation of a currency if that makes any sense. Too much money devalues a currency and too much know how of this system would do the same to the game market through saturation of fighting games. This is just a subjective assessment of mine after trying alot, but hey I could be very wrong…good luck though!
