I'll try to clarify the DI thing. Since it's the hardest technique to master, I understand there are still topics about it.
First: you have to DI as soon as possible after you got hit by an attack, always. This is the moment you need to DI.
As far as I know except for Quarter circle DI DI doesn't change the distance you fly, just the send of angle and the starting point.
It does change the distance you fly. If you aim the stick to the stage (still when you just got hit by, let's say, a Fsmash), you decrease the distance you're flying.
By aiming upward at the same time, you fly higher, which, again, makes you comeback from bigger hits.
So in that way it's the same for every character. However some characters are heavy and thus are best to DI to fly more vertical cause they might not hit the top cause of their weight.
Agreed. Lightweight characters can die too easly upward, I recommend to not DI too much upward with them.
But I'm not sure about that cause I don't know for sure if the speed that they fly with is reduced by the weight or that the weight just affects the distance that you fly before you can move again.
the "distance you fly without you can't do anything" is called stun. Lightweight characters doesn't have as much stun as heavyweight ones, and lightweight characters fly farther than heavy ones.
In other words: If you choose a lightweight, it's hard to your opponent to combo you because you fly always too far to get combo'ed, plus your stun is shorter so you can escape without trouble. It's exactly the opposite for heavy characters.
Distance is dependant on speed.
Do you mean the % you have when you get hit? Yes, it's right.
Weight changes horizontal speed and fallspeed changes vertical speed (I think).
The only right thing is the fact weight changes the distance you fly
In that way it can seem like DI is different between Jigglypuff and Falco, simply because Falco's vertical DI has a harder time of competing with his fallspeed.
I think the difference of DI between them is the best example.
My own tips:
- If you get hit by an upsmash, don't DI upward. DI downward as well as left or right tomaximise your chances of surviving
- People who just learnt the DI technique always DI toward their annemi after a hit. Don't do that. It's preferable to DI AWAY from your ennemi after a hit if you're at low percentage. It minimizes the chances you have to get combo'ed, plus it's harder for your opponent to combo you.
hopes it helped
