usually when the opponent is being hit, and not on block, the bomb will not freeze.
Bombs will not freeze if deployed WHILE the opponent is unable to hold block.
In other words, Bombs will freeze only if deployed WHILE:
1-the opponent is holding block
2-the opponent is walking/dashing/neutral
I have said this before, so here is the same thing in other words again, in case it is still unclear:
Bombs will only freeze if at the moment you finish dialing the input the opponent is at '1' or '2'.
If at the moment you finish dialing the input your opponent is:
a)performing any normal move or string
b)performing any special move
c)knocked down
d)in the air
e)in stagger state*
Bombs will NOT freeze
UFG... getting hit has nothing to do with it... its all about when the input is registered. You can put out a bomb while the opponent is at neutral and they will freeze no matter how you hit them.
On the video the bomb was deployed while kano was walking ... therefore the freeze.
*This breaks the "block" rule... dont know why, but thats how it goes.
