SMB2 SuperJump (Updated)

Finally! It is complete. A working SuperJump for use in your levels or episode!
Works just like the one in Super Mario Bros 2. Press and hold the DOWN key to charge up and Jump super high! Not really high.. Just enough though.

Screenshot: (Because I like them and I didn't want to take a video of me fumbling around with my own Superjump. ;-;)

Red: Normal Standing Jump - 4 Blocks
Orange: Running Jump - 5 Blocks
Purple: Super Jump - 6 Blocks!
Works on:
- Flat ground
- Slopes
- Npcs
- Linoleum
- Tile
- Wood
Wait... Wrong description.

Can't work:
- In mid-air
- In water or quicksand

One more thing to note is that this jump won't work if you're playing as Toad AND if you have a Leaf or a Tanooki suit.
( Giving a double jump AND a Super Jump to Toad? Now that can be a bit ridiculous. You have a leaf, just fly. )

Enjoy and please let me know if there is a problem or something that I've overlooked.

Is there a way I can implement the SuperJump from Super Mario Bros 2, into my episode using LunaLua?
I plan on using this with the Toad character and increasing his jump height by two extra blocks when used.
I have very little knowledge of Lunalua and I have no idea where to start with this one. Heh. >.>

Edit: I have made my own code with the help of some people here and I am now trying to get other stuff straight.

I have yet to figure out a few things.

- How to cancel out the normal Jump sound and replace it with a different one I have.
(Otherwise they both play at the same time. >.>)
- How to make a trail of particles when a Super Jump is preformed.
(When I try to use particles.api, the trail clears itself abruptly when I land)
- And how to make the jump work while standing on block-like NPCs.
(Such as Shy-guys, Bill-Blasters, Ice Blocks, and so on...)
Thanks to the people who helped me. :)

While these look nice and all... I still have no clue what to do with them.
Sorry, but i'm not familiar with the syntax of this language.

There are some helpful tutorials on the wiki, so I suggest you have a look there. They're a tiny bit out of date now, but they should still help.

Thank you, guys! I was able to make my own code for a Super jump and its works pretty ok! My problem is.. I cant seem to get this to work
when I'm on a Block-Like npc. Like a rocket engine block or a shy-guy. Is there anyway I could check if the player is on such objects?

Maybe Jump Bounce settings will help. Since those are still NPCs...

Define.JumpBounce
No. That's not even it (Defines.jumpheight_bounce), however that wouldn't work anyway. When jumping off of an NPC with playerblocktop equal to 1, it's treated as a normal jump. You need to check if player.speedY is 0 and do an NPC.getIntersecting() for the space underneath the player

Or you could be sensible and do it the non-dumb way by loading classExpander.lua and just using the "isOnGround" check. Even if you don't want to do that you can use player mem addresses to perform that check. No idea why you thought you'd need getIntersecting.

Didn't know that existed, so you'll want to check if the NPC:mem field 0x176 is greater than 0

Check if the NPC:mem field 0x176 is greater than 0?

So I'd just put this in the section where I check if the player is on the ground, not in the water, etc?
Or am I being a tad on the dense side here?

Again. You can just load the classExpander and there's literally a test for "isOnGround" which is much more reliable than doing it yourself.

I'm still confused as to what to do. I mean.. I only know what Pyro's videos taught me.
(And even then, I didn't watch them all yet due to the stuff i've needed to do recently.)
