NSMB - Extended Powerups

[flint spire]

The main goal of this project is to bring existing Powerups from other Mario games (Propeller Cap, Super Leaf etc.) into NSMBDS.
This mod expands the amount of Powerups slots available, meaning modders won't need to replace/modify existing Powerups to create custom Powerups.

This isn't in a releasable state yet, but I plan on releasing a public Github for this once I get a bit of time and cleaned up a few bits.
If you'd like to contribute suggestions, code, models etc. towards a Powerup, please do!
For now, I'll only be adding existing powerups, no custom ones.

Also shout out to @hidden nebula for his work on the Iceflower, it helped me get started on this!

[carmine flare]

impressive work

[shadow shale]

god's work, especially given the repo is public

[steep bay]

whats the code look like rn? As I want to see how your doing it because im having a problem were the player gets stack in a grow animation with the extended states

[stray lodge]

🔥🔥🔥

[tardy sequoia]

yooo this is looking sick so far, awesome job

[stray lodge]

I'll contribute my boomerang if jpg lets me

[carmine flare]

@leaden berry ping cause youll prolly wanna see this anyway

[steep bay]

oh yeah, nld has shared his code for this before which is what Im using, I may aswell repost it here

[leaden berry]

I can send the models here for him/her, u can share the code 😉

[flint spire]

I can take a look later but I definitely didn't need to extend this many tables to get this working

[leaden berry]

The problem is that i think i will need a diferent way from making my model of boomerang

Since i did a cursed thing

(2 textures and palletes)

[flint spire]

Oh yeah the ones in the video are crappy ones I hacked together from converted the Wii U models lol

[leaden berry]

And idk if (probably its possible) if its possible to change both textures and palletes

[leaden berry]

@flint spire you need to ask william, because idk if he will share, but if you want i can share the shuriken flower with u, thought it replaces the blueshell, and have some other codes that sacrifices the headless mario (that can be changed in code to change to another model i think?)

[flint spire]

Right now I'm only interested in adding existing powerups from other games, custom ones would be way after

[leaden berry]

Gotcha

[steep bay]

yeah you dont need. But that includes every reffrence to the powerups

its probably best to have them all for any random checks that we may miss

[flint spire]

Yeah I skipped all that.

Instead, I ncp_over my new table over the dword_2122CA0 array.

Then, I recreated the following table below it ledgeWalkAnimSpeeds, which only has a single pointer to repoint. This frees up some memory that we can extend the table to, around 5 new powerup slots or so.

For a permanent future solution though yeah, we'd want a better solution than this because this solution is limited to about 6/7 new powerups.

[flint spire]

Give this a go

[tardy sequoia]

are you planning on making this open source?

[flint spire]

Yep, once it's cleaned up

[tardy sequoia]

the ''add more powerups instead of replace'' part, not the powerups themselves lol

[tardy sequoia]

ohhh i see i see

[flint spire]

Still some lacking things, like the new model not rendering on the world map etc.

Right now, it's just in a non-crashing state lol

[vocal harness]

Wow. Was That The New NSMB Mod With New Powerups. I Would Love That!

[steep bay]

ahh I see what you did

how did you do the subscreen graphics btw

[flint spire]

The 64x64 mushroom sprite was reduced to 32x32, for extra room for new sprite slots (not ideal). Then some powerup checks and some custom drawBNCLSpriteSub calls.

So that still needs to be expanded so we can use 64x64 for all sprites

[steep bay]

ahh ok

[tardy sequoia]

would it perhaps be possible to put the custom powerups on their own .ncg and .ncl?

tho i heard that the ui in code is tedious to deal with so

[steep bay]

yeah, oam is painful

[flint spire]

Very, probably the trickiest part so far

[steep bay]

I could never pull it off

[flint spire]

Temporary fix for now, but once I figure out how to expand the bottom screen .ncg, we can support 64x64 sprites

[steep bay]

wouldnt doing that overwrite some data in this array under the powerup state table?

oh its ledge related stuff

and you rewrote the ledge walk anim speed

[flint spire]

Yep, I rewrite that table:

So once 5+ powerups are added, this will have to be changed

[steep bay]

thats a smart way of going about it

probably better then having every reffrence to the powerup table changed

[flint spire]

For now anyways 😄

Where do you currently hook in your custom powerup logic? Right now I'm using a crappy global class for testing

[steep bay]

well umm. The red star stuff is all still attached to an actor and the blue shell modifications are in playerUpdateMain...

Im using shity places too

[stray lodge]

dawg u gotta update this looks pretty ancient

[steep bay]

just tried that method and removed every call to the new powerup table and replaced the exsisting one aswell as that speed table and it fixed that bug I had with the mega growing stuff

[steep bay]

#nsmb-programming message this is the issue I was having with nlds method btw

[celest needle]

PLEASE LET ME DO THE SUPER LEAF 😭
(its actually one of my main motivations to learn how to make code hacks)

i planned it for my hack, but knowing myself and knowing that i dont know how to make code hacks yet, this might take a year i guess? idk

i probably overreacted 😭

[flint spire]

Great, yeah don't use Unk6 or Unk7 at all

[flint spire]

Do you have the models for the powerup and ears?

[celest needle]

no

what i meant is that i actually planned to make the super leaf for my hack in the future

(and i guess i could have made it for this "power up pack"?)

[steep bay]

is ur propeller shroom a custom item btw? or is it an actor?

[flint spire]

Item

[celest needle]

i'm pretty sure JPG64 wont have any problem to make the models tho

[steep bay]

yeah I need to make my redstar one still

[flint spire]

I mean you probably need to know how to code to do that lol, there's a few leaf like custom powerups floating around wouldn't be hard to create tbh

[celest needle]

yea true, tho i kinda wanted to learn how to code as i would learn how to make code hacks

and i think setting myself a goal could help (in this case making code hacks)

[flint spire]

I think I'd also like to make the Mushroom, Fireflower and BlueShell use 3D models instead

[tardy sequoia]

I actually wanted to try doing that for every powerup aswell since I made some models a while ago, but I lack coding knowledge and the models are a lil unoptimized regardless lol

[flint spire]

Mind sending me those models? I could give it a go

[celest needle]

i noticed that the models (propeller mushroom and propeller hat) don't have shading tho

[tardy sequoia]

sure, I’ll do it later or tomorrow since i can’t rn

[flint spire]

In the video? Yeah they are just crappy .obj rips I did in like 5 mins

[celest needle]

oh ok

[flint spire]

Will definitely need proper models when it's ready

[carmine flare]

outta curiosity por que

[celest needle]

alright then

[tardy sequoia]

I think to make it more consistent since mega and propeller are 3d

tho even then sprites aren’t bad

but models would look better and can even have cooler animations

[flint spire]

exactly 👍

[steep bay]

It’s also useful for powerups that’s graphics won’t fit into a 16x16 space

[flint spire]

Also much easier to add 3D models, 2D sprite stuff is surprisingly finicky

[steep bay]

That too

[tardy sequoia]

oh interesting

does the same apply to nsbtx polygons in either of those? (talking about pipes and mushroom platforms for example)

[steep bay]

those are easy, they use the 3d engine

[flint spire]

Some model & texture improvements for Mario. The powerup itself still looks pretty rough though.

[steep bay]

i was trying to write code to also create an item for the redstar instead of an actor but I have this problem. I was basing it off nlds ice flower code

I also moved all the redstar flight code from the actor to a playerhook

I guess I cant call c++ functions like this from lines of asm

[hidden nebula]

this now makes me want to make an inventory on the wm

[leaden berry]

I love making 3d stuff so yeah i can help with every model needed

[teal lagoon]

This is gonna be a very interesting project

[steep bay]

that would be interesting

probably pretty broken with the reserve powerup system though

[hidden nebula]

there are ways to make both work

[soft ermine]

I think she meant OP broken

[tardy sequoia]

maybe u need to shad smooth the propeller so it gets shading? idk how it works tho

[leaden berry]

I will make a propeller shroom model for u, since that one is high poly and will not work in some emulators

[hidden nebula]

oh yea ofc

[fallow panther]

Thought it was a port of power ups from Mario vs Luigi online

[steep bay]

made some more progress, I still need to get additional items working though

[soft ermine]

[steep bay]

i think im going to need help getting the item part working

im not smart enough for it

My other option is to use the current red star actor and make the boo block spawn it or smth

[flint spire]

What's the issue again?

[steep bay]

this is what I tried, its based on nlds code. I think Im going to try writing my own code for it, ill probably do it all in asm

[flint spire]

Which function are you having trouble with?

[steep bay]

I dont know tbh, I think I just need to restart and not base it off nlds code

[flint spire]

My code atm is still a bit weird for consuming, probably just be easier to rewrite some of these tables

I'm focusing on the crash bugs rn, there's just one or two more world map related crashes left to fix

After that, I'll clean up all these consume calls

[steep bay]

I’m going to look into the item part after school today. I think I should be able to pull it off

[flint spire]

Quick update: https://youtu.be/SJug3H9pUsU

Main changes:

• Powerups now overwrite each other and follow a system more similar Super Mario World.
  (For example, picking up a Fireflower while having a Blueshell will swap to the Fireflower powerup and put a Blueshell into Inventory.)
• Can now drop Custom Powerups from Inventory.
• Luigi now has a Propeller model.

[steep bay]

nice

this is what my current system is like. Decided to just redo the whole inventory item spawning thing so I can make it do whatever I want

[flint spire]

Looks pretty good, is the star still a custom actor?

[steep bay]

yeah, just going to make them spawn out of boo blocks probably

and I could probably tie what the boo block spawns to some random bit of stage data

thats unused

[flint spire]

If you make it an item, you could probably just overwrite the Blueshell block with whatever item you want for that level

But either works

[mystic sundial]

hey, y'know how in the 2-player mode of NSMB2 has the "go into the bubble button"? would a system like that be replicatable with this?

[steep bay]

Why would you want that in a single player game

[flint spire]

Yep, I'd like to eventually add some sort of bubble respawn system to the co-op hack but I wouldn't let the player simply press a button to go into one

[mystic sundial]

Cool. Also, I'm not sure what power-ups you have planned for this, but will the Super Acorn be in it? That'd be neat as well, although that might be a more involved power-up to make based on how the propeller mushroom works. Still, I'd be cool.

[flint spire]

It's pretty much just the racoon leaf isn't it? Because I'll definitely be adding that at some stage. Coding wise, should be easy, I just don't have any models for it yet 😅

[leaden berry]

My mod have a super acorn code, if Willian let me I would share with shadey

[flint spire]

This will eventually be an open source project that people can use for mods so would be great to have, thanks! I can touch up any code if needed etc.

[leaden berry]

Oki 😉

[steep bay]

Did you ever get around to writing code to load the custom powerups reserve textures on the world map? Im just asking to see if I can deal with less oam crap

[flint spire]

The reserve there you can freely just expand the file and it will load

It's the bottom screen one in level that has the hardcoded limit

[steep bay]

[flint spire]

Use this hook too to draw the OAMAttr you want (on the World Map):

void call_020CF630_ov_08(int rectangleNumber, GXOamAttr *entries, OAM::Flags flip, int palette, int unk1, Vec2 *scale, int unk2, s16* rotCenter, OAM::Settings priority, int xOffset, int yOffset)
{
}

[steep bay]

[mystic sundial]

neat, also, is the ice flower going to be in this? that'd also be really cool (pun slightly intended).

[flint spire]

Yup, NLD gave me permission to add it, I just haven't had time to work on this lately sadly

[steep bay]

Nice, atleast you dont have to worry about making it a tiny graphic

[gray acorn]

Sorry for bumping the thread, but how's the hack going?

[leaden berry]

#1401307142459228390

[gray acorn]

Ah so it turned into co-op?

[leaden berry]

This project was for cooop

[gray acorn]

A

[stray lodge]

classic jpg, spreading misinformation

[leaden berry]

Wait its not for coop? 😭

[celest needle]

i think it's more like, the projects kinda merged, i think

[gray acorn]

ª

[flint spire]

I was using co-op as a base but I might also have it as a separate thing patch, will have to see how the base ROM work goes for the co-op hack

Everything I code is always co-op compatible these days

[graceful willow]

demo playable?

[flint spire]

Not atm, never got around to finishing this sadly. Whenever I do come back to it, it will probably be merged into the co-op hack instead!

[distant magnet]

🙁

[buoyant oak]

man this is cool

sucks its not being worked on now

[soft ermine]

NSMB - Extended Powerups

[flint spire]

Whenever I come back to NSMBDS stuff, I'll pick this up again. No time to atm sadly.
