So... what's a glitch, then? I mean, obviously the black hole GLITCH isn't a glitch, because, hey, Sakurai didn't intentionally add a feature to make it impossible for you to do it. There's a difference between a combo that sakurai didn't visualize and a MECHANIC he didn't visualize. He obviously new that attacks would be linked in ingenious ways, techniques would be used innovatively, etc., but he did NOT know that you were going to be able to slide around on the ground like a ****ing tobogganer. Yes, it's explainable. But think about this- if someone discovered that you could, I don't know, jump and airdodge at the exact same time to become invincible for ten seconds, wouldn't it be a glitch? Even if it makes sense, given the mechanics of the game?
Air dodging was a mechanic that Sakurai didn't visualize? Or did you mean jumping was a mechanic Sakurai didn't visualize? Or did you mean keeping momentum when you landed, which is the entire reason they bothered to code LANDINGFALLSPECIAL in the first place, was something he didn't visualize?
Realize that using a horizontal up-b near the ground and sliding forward when you land is obviously not an abuse of the game's mechanics, it was what Sakurai thought made sense.
Now, realize that airdodging serves the exact same function as a traditional up-b. It manually moves you forward, in the air. Realize that unlike an up-b, however, its angle could be more easily chosen.
To quote you, "he obviously knew that attacks would be linked in ingenious ways, techniques would be innovated". The only word I'm going to take out, is attacks. I'll replace it with "commands". Still the same thing.
"he obviously knew that commands would be linked in ingenious ways, techniques would be innovated". All wavedashing is, is pressing Y and L really fast. Manipulate where you wavedash by moving the analog around below the x-axis.
He pictured momentum preservation as a little, subtle thing. An extra extra tacked on to provide some distance here and there. Dashing was for normal movement. We started to actually, you know, use the
momentum to
move. Obviously he didn't predict us "tobogganing around", but he didn't predict us hopping around like frogs next to a shield shine-drilling.
If the mechanics of the game were such that being invincible for a certain amount of time was an integral part of the fighting system, and all characters had a move that gave you some level of invincibility, then that would make sense in the "physics" of the game.
Just how the mechanics of our game are such that moving our characters a certain distance is already an integral part of the fighting system, something that, before wavedashing, every character already had.
So if some characters had moves that gave them invincibility for 6s, and their airdodge/jump gave them invincibility for 10s, that's the same as Luigi's dash making him move at regular velocity, and his
wavedash making him move at high velocity.
