An example of what I’m talking about is Kuma’s crouching medium kick into Frolicking Bear. The normal commands for this would just be medium kick canceled into half circle back + medium kick. However, if you input the medium kick in the middle of the half circle back and the rest of the motion is fast enough you can skip the input of that last medium kick and the Frolicking Bear will still come out. So here you have one medium kick motion causing two attacks.This effect seems to affect a whole bunch of cancelable moves and often comes out unintentionally.
As someone who is relatively new to modern fighting games I find this rather bizarre and sometimes annoying. It’s hard for me because I’m using a d-pad, so every forward-back motion is registered as a half circle movement and sometimes random moves will come out when I’m trying to change directions. I’d like to know if there is a general explanation for how this mechanic works and what I can do to deal with it effectively.
