welcome to smashboards! just wanted to let you know that you probably meant "hitbox". "hurtbox" refers to the area where a character is vulnerable. when a hitbox meets a hurtbox, the hurtbox takes damage.
Thanks for the warm welcome! ^_^
Hmm, I'm pretty sure I'm using the correct term to describe the phenomenon, but I'm willing to describe what I mean for greater precision, and if I'm wrong, I'm willing to listen and learn to understand better.
Once you place a bomb, based on my understanding, it activates under 2 conditions:
(1) Timer - After a certain amount of time, it will go off. Period.
(2) Hurtbox Activation - That means, when your opponent uses an attack, and the opponent's hitbox intersects with the bomb's hurtbox, the bomb is activated. This neutralizes many projectiles, and can hurt opponents if their hitbox and hurtbox aren't disjointed. This isn't a hitbox activation, because a character can freely walk through the area of the bomb without activating it (until the timer goes off). My understanding of this might still be flawed, because it's hard to get a CPU to attack a morph bomb for proper testing. I'm specifically interested in testing this against Marth, because I want to see if he can swat the bomb to remove it from the field without taking damage, but again, CPU doesn't do what I want it to. It might only activate on certain types of attacks, and not others.
I hope that makes sense. ^_^
just meant that you can jab into bomb to make it safe or combo into the second jab. it's pretty intuitive.
Jab doesn't have enough hitstun to make it safe to place a bomb. Jab 1 doesn't have enough hitstun to combo properly into jab 2. For me, I don't think I'd use a bomb while my opponent is within range of jab, because placing a bomb is punishable at that range. I think placing a bomb should only be used when my opponent is still spaced far enough out that I can place the bomb before they can finish their approach and hit me, but that's just me.
