PS: For a Tornado with FLUDD spraying, Would just changing the animation of FLUDD to where Mario spins make the water work right hmm? some of it would spray on the Z axis >_O ... I'll test if it works that way (actually it's called the X axis that goes toward your camera in Brawl, the Z axis is the one that goes left/right/horizontal which you would think to call the X axis)

PSS: O uhh, I think I also messed with the max angle it can turn, so it can spray up farther (and down farther?). What i need to do though is make it turn FASTER, because the spray ends before you can turn it up all that far.

-Created on Mario's Minus 2.0 .pac (outdated) (I do have 2.1.1 but I didn't want to confuse the files in the newest build so I chose to use 2.0, sorry, I can easily recreate the changes on the 2.1.1 .pac if anyone cares [which I will do when I learn how to add Jump canceling to its grounded use)

-Keep in mind this can be replicated onto Squirtle's water gun, if something like this is more suiting to him, though his side-b is his inertia move (along with hydro-planing his up-smash, which I think shell-shifting should be focused on to be Minus'ed more like his side-b was)

The FLUDD works and sprays in whatever direction he turns (except for the Z-axis, the water is only on the 2d plain so it picks the closest X axis for the water to be sprayed even if Mario is facing right at the screen)(Also note in BrawlBox the Z axis is the horizontal one while the X axis zooms in/out of the screen). Also, when hes spraying in the opposite direction of where he is suppose to be spraying (forward) the water seems to still push in the forward direction (so that it brings people closer to Mario when he is spraying it backwards during the rotation). This would make a FLUDD-NADO useful to use when people are behind him as the water would push them into Mario's tornado.

What I'm going to do: If I replace Mario's FLUDD firing animation with his down-air animation, and figure out to how to add hitboxes to his limbs (like the original tornado, or like P:M's but with the FLUDD still working) he will have a FLUDD-NADO (though the actual FLUDD instrument will be graphed onto his skin instead of him holding it..that is unless I delete the FLUDD texture or make it transparent[blank]). Then I will need to boost the water's attributes to have more push-back (since hes spraying only 25% in each direction he rotates, 50% of it is being wasted in the Z-axis, well actually in Brawl they called it the X axis that goes towards your screen..weird huh? You would think to call it the Z but no they made it the X, hence in BrawlBox if you edit an animation and change the Z axis it will go to the left or right not bigger/smaller.). All of this I believe is possible; replace animation, add hit-boxes in PSA, re-color the FLUDD's model texture to be completely translucent/delete (I know this is possible since I've seen Ike and Ganon textures that are lacking their cape/headband as well as snake lacking gear on his waist so that he's a WWE wrestler), then change the "Water Pushback" that's normally 35 (I'll change it to 110)

EDIT: also I would need to find out how to make Mario rise when you tab "B" (which P:M did) I'm thinking It might be best to copy/paste the stuff from Luigi's .pac in PSA for this and the hit-boxes, but still somehow keeping the FLUDD. Actually, I don't think you can do that with just "copying" stuff from Luigi's .pac, I think you have to remake the coding (which I'm guessing P:M did). So this goes to all the people who want just the tornado for his Down-B, they would have to use P:M's tornado (and for some reason they don't like to share codes and such between the projects or something)

at least on his down-b (It might be possible to put it on his up-b, but then you have to somehow get rid of the charging part) but anyways yeah: If I figure out which bones are the ones that make him grasp on to his FLUDD (rather than when he uses the Tornado animation instead and the FLUDD just stays on his back and sprays), then I think I can move them slightly(his arms or such) to hold the FLUDD downwards, and then Just create upward momentum [add the "Add/Set [Vertical] momentum" to him, so far this method only works while hes already in the air though, I think I could just use some transportation thing to make him an inch of the ground so it works on ground use].
The end result wouldn't be exactly the Rocket Nozzle where it is already pointed downward while on his back but his hands/arms/whatever bone required would be spraying it downward (but to simulate the same kind of lift off water effect)
Then I would just use the d-pad idea mentioned earlier, where Left/right d-pad press would give him horizontal momentum too, so that he could move to the sides. Also I would change his backwards inertia while spraying to 0, so that only the d-pad would give him the controllable movement; as well as increase his FLUDD spraying length so that it lasts longer like the Rocket Nozzle did.[both these are easily done in hex editing using HxD and The list of things you can hex to change ] You will also need the a Decimal/Hex/FloatingPoint converter And then just ask people for help on the tips for doing this
