Undertale Purple

[sacred depot]

This looks amazing so far!

[grand folio]

works like a charm

[grand folio]

scripts can be called by functions

[torpid agate]

!

[grand folio]

here is the code though (called in ScriptGroup#update())

var total:Float = 0.0;

function update(elapsed:Float)
{
    total += elapsed;
    trace(total);
}

[torpid agate]

are you using Iris script?

[grand folio]

I'm using Codename Engine's hscript-improved, I forked it myself if I would like my own changes

[torpid agate]

what

What does the codename's fork offer?

[grand folio]

It was just recommended to me

[torpid agate]

fair

[grand folio]

I do want to minimize a lot of script calls, so I need a clever way to still have some compiled code be the one doing most of the work

there has been a little field in RoomData.hx left unused for over a month now

good opportunity to use it now

[torpid agate]

sounds cool

[winged condor]

custom classes, enum, abstract and typedef support, script packing, parent vars, etc

[torpid agate]

parent vars? Explícate

[winged condor]

osea pones de parent a playstate y si en playstate hay una var llamada yoqse "algo" en el script en vez de hacer FlxG.state.algo.foo() puedes hacer algo.foo() directamente

[torpid agate]

oooo

y se puede tipo algo = otra cosa y se combine con el Playstat?

Sorry, eye, for taking the chat off topic.

[grand folio]

i was sleeping

[torpid agate]

sjsk

[grand folio]

not very easy to recreate, i have to compare side-by-side constantly

good news is that the editor is atleast robust enough for me to continue tomorrow

[grand folio]

ironically as i say that

i forgot to save

[torpid agate]

KEKDKS

NOPO

[grand folio]

one of the more complicated systems :P

one of my thoughts is using a neat structure to contain every encounter, having scripts manage the attacks

[grand folio]

[showcase] Posting the build of the latest commit, I will need some feedback for the editors for future purposes

[idle plank]

:v

[grand folio]

odd, might be drivers

i don't have any shaders implemented

[idle plank]

okokok

[grand folio]

lemme know your gpu (display adapter), might be helpful in seeing if i can fix this problem

[torpid agate]

@idle plank

[idle plank]

to be honest, i ont even know if I have a gpu

[torpid agate]

por qué tan poca ram usable wtf

[idle plank]

nose

[idle plank]

oh, its a gl error

[meager stirrup]

[cedar arrow]

😭

[grand folio]

you can actually just do battleCamera.bgColor.alpha = 0; and have a DELTARUNE-styled battle to some capacity

[honest tusk]

Deltarune tomorrow

[cedar arrow]

In 2 days actually

[grand folio]

depends on the timezone, but it's generally when the pricy 2 releases

[cedar arrow]

Peaktendo Switch 2

[grand folio]

i naturally hate nintendo's legal practices so i don't care about the Switch 2, only Deltarune and Silksong

[grand folio]

banger

[grand folio]

each enemy has a script

[finite kestrel]

As in script how do u do that

Since

You could make a hx for the entitys

And then make hx for the entity using the entity hx

Idk

[grand folio]

here are the scripts

[finite kestrel]

OMG NO WAY TYSM?!?

[grand folio]

i use this hscript fork https://github.com/EyeDaleHim/hscript-improved

[finite kestrel]

Ohhhhhhhh

[grand folio]

only changes you'll wanna do is in ScriptPreset.hx, contains some Undertale Purple stuff

the files i shared may get outdated quick, i'm constantly updating these in the game

[finite kestrel]

OH OKAY ILL CHANGE IT TYSM AGAIN

[grand folio]

yw

[grand folio]

i mean, i tried

i'll fix it

[torpid agate]

looks cool

[grand folio]

this feels like overengineering, but i've made some helper recursive class for things like "Fight", "Act", "Item", "Mercy", etc

in terms of depth, realistically, only 1-2 branches are enough for most things in undertale

[grand folio]

build with glsl 330

[finite kestrel]

Crash

[grand folio]

this is the real build with glsl 330

apparently my compiler didn't update the shader file

[grand folio]

try this one ^^

[finite kestrel]

IT WORK

[pine thorn]

Where are you setting the GLSL version?

[idle plank]

it works now

[idle plank]

how can i enter to the map editor

[grand folio]

press F5

[grand folio]

i'm shadowing openfl.display.Shader at the moment

[idle plank]

hmmm

there is a bug, two events can occur at the same time, which crashes the game. it happened to me that the battle event occurred and at the same time i activated the room change event, which crashed the game

[grand folio]

could just disable room change nodes when you enter a battle then

thanks

[idle plank]

i was in the beginning room

[grand folio]

i don't think it matters what room, it's more of a general bug

[idle plank]

ye

[grand folio]

i feel like this bug could still happen in some form, but right now, code's not mature enough for me to fix bugs so early on, so that should be noted

[torpid agate]

Dummy

[torpid agate]

Did Percy say all that?

[grand folio]

no this is the error message

[torpid agate]

I already know, the message just funi

[grand folio]

in which case, no they're a silent(?) protagonist

[torpid agate]

Who says that narrator's voice isn't the protagonist speaking?

[grand folio]

well anyways

the text isn't even localized yet

[torpid agate]

okii

[torpid agate]

Clearly that must happen

[proper trout]

make it a tiny tiny bit faster

[grand folio]

i actually already addressed that yesterday

the soul was using 90 (3 pixels per second in 30 FPS) as its base value

the value is now set to 120 (4 pixels per second in 30 FPS)

[proper trout]

the souls determination to escape has increased!

[grand folio]

that one was me forgetting to set immovable to true

for the borders

[proper trout]

oki

[grand folio]

i'm getting a clearer idea of how scripts should interact with the battle system, and so for the other systems

[grand folio]

there's ✨ gameplay ✨

[meager sluice]

@everyone - b

[meager stirrup]

make the flixels' be grass

grass, job applications, showers

peak

[proper trout]

uh im not sure thats needed uhm........

the ping ofc

[grand folio]

only pings people who joined this thread

[severe breach]

[winged condor]

[torpid agate]

But wasn't the purple soul moving on threads?

[grand folio]

no?

i never said anything like that

[torpid agate]

Sorry if I miss much, it's 3:40 and I woke up from thirst, but I remember that in the battle of Muffet the soul was moved by strings, not threads

[grand folio]

it's not fun to limit gameplay to a specific gimmick

[torpid agate]

fair enough

[proper trout]

how would u go about getting the needed assets

[grand folio]

i already have them

[grand folio]

there is a tool named "UndertaleModTool"

which allows you to read a data.win file

[proper trout]

can you possibly send the assets of undertale to me,,, i dont have the game in my steam library

[grand folio]

you can get them on the internet, it's impractical for me atm

[proper trout]

i found frisk on https://www.spriters-resource.com/pc_computer/undertale/sheet/75941/

[grand folio]

not bad, i just don't like that they're making it fancy with making it non-transparent

[proper trout]

steamunlocked my beloved 🔪

i download undertale using steamunlocked

[proper trout]

gulp gulp i did it

thank you @/eyedalehim and @/ceroba for inspiring me!!!!

[torpid agate]

Yore welcome

[grand folio]

I'm debating on re-open-sourcing Undertale Purple's code as a WIP Undertale engine in Haxe

It's exhausting just doing the programming all on my own, and I would like pointers at some point, and I'll have to dedicate less time for UT Purple at some point

As for another sudden rewrite, I think I can safely lock in this one as it's the one with most progress so far

[torpid agate]

I say keep it private but tell people you trust, "Hey, give me your opinion or help me with this and that."

[torpid agate]

Believe me, there will be someone who steals the code and uploads it as their own

[grand folio]

That's the situation that I've been living in

[grand folio]

????

I'm not worried about stealers, the opinion of experts are more valuable to me

[torpid agate]

hm

Okay then open it but remove things that have to do directly with purple

Just leave the essentials, let's say

[grand folio]

That has been the plan

I don't know why I'm annoyed by this

[torpid agate]

Wdym

[winged condor]

wtf

[torpid agate]

callat

[grand folio]

since i have school tomorrow (Monday), i'm going to try to finish up what isn't related to the attack system

fight animation, item healing, damage text, enemy health, etc

I'm slumping very hard on the attack system

[torpid agate]

@grand folio how exactly do you make the menus?

I did something like a system of submenus and menus

[grand folio]

They're substates

[torpid agate]

ooo

[grand folio]

fyi, you can add substates in substates, like a recurse

what you are doing is a bit recreating of that behavior

[torpid agate]

I realized that, but I guess it gives me 0.1% more handling.

[winged condor]

is that possible?

[grand folio]

yes, that has always been a thing

[torpid agate]

Theoretically a FlxSubstate extends from FlxState

[grand folio]

might be a little too late to adopt ECS at the moment

[sacred depot]

ecs?

[grand folio]

i've been obsessing over it and its benefits, but i feel like there's too much to change

[grand folio]

entity-component-system

[sacred depot]

ohh

[grand folio]

I've been liking ECS lately and would definitely fit all my use cases, but I feel like there's a world out there that'd be better if I benefited from ECS later

[grand folio]

Run!

[sacred depot]

the way the music stops is too funny for me for some reason

[torpid agate]

funi

[grand folio]

Damage

[grand folio]

I spent half an hour figuring out why damagePlayer was called twice, only to realize my script was calling it

[torpid agate]

wat

[grand folio]

At some point, attackScript calls hitPlayer which will eventually call damagePlayer(1) when I'm about to do that

resulting in two calls of the same thing

[torpid agate]

ooooooooo

[pine thorn]

I'm replaying Undertale and I noticed the same issue you described in #flixel a while ago (Notice mixels in a part of Frisk's hair and nose). This is also in fullscreen, so maybe it's not an issue with Flixel?

[proper trout]

sometimes i feel like frisk's eyes get a little smaller in height when walking.. kinda off to me???

[grand folio]

What resolution do you have in fullscreen?

[pine thorn]

I'm on a 1920x1080 monitor

[grand folio]

there's no way

Width Scaling: 1920 / 640 = 3
Height Scaling: 1080 / 480 = 2.25

if we need fullscreen, we need perfect integer scaling to solve those mixels

mixels might only be noticeable vertically but not horizontally, so i believe this may be why

[torpid agate]

In fact, even the console ports of Undertale aren't perfect, there's a very noticeable line at the borders

black line

[grand folio]

Depends on how noticeable it is, I'm not counting it if it's just a line

[torpid agate]

Well, do you remember that I had that problem a long time ago?

It turns out Undertale uses 1080p for the borders, so...

[grand folio]

I'm not good at memorization, no

[plucky grail]

@grand folio ik you probably talked about this before, but I'm curious as to how you (plan to) handle dialogue for this game

how will you store it?

[grand folio]

keys to get text

it's not that different from how undertale/deltarune gets text for dialogues

[plucky grail]

elaborate?

like a map?

[grand folio]

yeah sure

i store all my dialogue keys and contents in JSON files

[plucky grail]

how's it look?

I got suggested json for dialogue but I decided against it, it seemed a bit too rigid and annoying

[grand folio]

{
    "battle_generic_check": {"contents": "* Check"},
    "battle_generic_talk": {"contents": "* Talk"},
    "battle_generic_mercy_spare": {"contents": "* Spare"},
    "battle_generic_mercy_flee": {"contents": "* Flee"}
}

-# you can omit {"contents"} here and just have a single string, it's converted to {"contents": string} anyway

you can use what feels right for you with dialogue, i made this decision out of immediate requirement

[plucky grail]

fair enough

we ended up opting for xml

[grand folio]

i remember renaine using it, so you got points there

[plucky grail]

funny you should mention renaine because I stole the idea from them

lol

[grand folio]

lol

[plucky grail]

still not sure how to format it all

although this seems like a good place to start

[grand folio]

oh, that's a good idea actually, i've actually only been using scripts to add lines in dialogues

i'll add it to the list

[plucky grail]

how I'll do dialogue specific events I'm not sure

that's still something I'm not sure on

[grand folio]

what i'm thinking is that you send a "signal" to scripts or components that will act based on those dialogue events

[fleet merlin]

(jk have fun just remember to have a schema)

[grand folio]

i haven't been active due to school but here we implement yellow color if enemies can be spared

[idle plank]

ou yeah

[winged condor]

You used Null Object Reference

[sacred depot]

• You crashed the game.

[grand folio]

[winged condor]

how do i check that

[grand folio]

it's a build script

[subtle iris]

is it okay if i use this

[grand folio]

yes

[subtle iris]

thank

[idle plank]

ewe

[grand folio]

i'm prepared to lose my sanity (again)

[torpid agate]

Ohh, I made one, need help? I'm literally kind of good at parsing commands because of discord bots skslsk

[grand folio]

nah i'm good, i figured it out myself

[torpid agate]

okii

I made one with everything and description and search for the name

[idle plank]

toby fox just released a page that lets you express how undertale changed your life, its for the 10th anniversary

[sacred depot]

yee I posted mine

[idle plank]

👍

[grand folio]

i don't have my laptop, so i have another laptop, which is my father's laptop

but i refuse to install any VSC on it

too lazy

[idle plank]

use neko

[grand folio]

first i need to use my GitHub account

where my 2FA don't work

[idle plank]

sheeesh

[grand folio]

now i have to wait for my laptop

to get fixed

[idle plank]

👍

[grand folio]

pages

[subtle iris]

nice

[torpid agate]

ohhh

it seems very cool but

why?

[grand folio]

ran out of space

to display stats stuff

[torpid agate]

Spell related, right?

[grand folio]

sure

[torpid agate]

And it would be like the TP or something like SP

more different to deltarune I mean

[grand folio]

i could always say "mana" but does feel different

[torpid agate]

Why not Spell Points?

I mean, I feel like it fits perfectly with Undertale's style

(I'm trying to persuade you to call it same as me)

[grand folio]

feels uncreative

[torpid agate]

WHY

[grand folio]

maybe i like being different

i think "SP" only uncreative, to me

[torpid agate]

i mean, it doesn't matter how it is really called

[torpid agate]

mama or sp it's fine

I just call it that to put it next to the health bar

[idle plank]

tandem points

[torpid agate]

@grand folio I see it something like this:

[grand folio]

i think i already have the ui change with spells in mind

i'm trying not to change the idea since i want to lock it in for ut purple and think about feedback later

[torpid agate]

How are you doing it?, I'm not using that at all, bc, well, the idea of magic is only for monsters and it's too secondary

[grand folio]

my idea is to have the mana bar be placed where TP bar is in deltarune

i don't really want to have people to re-learn the UI again and for returning players, they have to come back and get used to it again

[torpid agate]

It sounds good

[torpid agate]

@grand folio something like this

?

OH I FORGOT THAT TP BAR IS ON LEFT

its

[grand folio]

yeah it should be on the left

though i'd probably simplify the design

since i need that undertale feel

[torpid agate]

Like this?

[grand folio]

i'd decide the design myself anyway, but something like that

[torpid agate]

ohhh

Sorry if I insist too much, I like to imagine it

[grand folio]

don't give me ideas, i'm to o slow

[torpid agate]

skslsk

It's okii

[plucky grail]

see I just don't feel this fits undertale

[plucky grail]

or this

feels too fangamey

[grand folio]

we aren't trying to make an undertale game

we are making an undertale fangame

[plucky grail]

ehhh it's hard to say how it makes me feel without saying it like that

[grand folio]

i dislike the notion that an undertale fangame is restricted to have to be like undertale

[plucky grail]

I guess it feels more like

[grand folio]

limits creativity and puts pressure on me to have to come up with something

[plucky grail]

it's trying way too hard

to look seamless

idk that's just what I think

[grand folio]

i don't think "this feels like an undertale fangame" will hardly change my direction at all

i haven't even released an undertale project yet to actually get proper feedback

or know what it's like

which is why i'm mostly listening to my own experiences and interpretations of feedback from undertale

[torpid agate]

Nono, I understand what you're talking about as something more vanilla

[plucky grail]

hey man you do you

I'm jus saying what's on my mind

[grand folio]

qol

[grand folio]

item usage in overworld

[severe breach]

My favorite, %1.

[idle plank]

%1, the most iconic object of undertale

[proper trout]

it isnt honestly

[grand folio]

Do not disrespect the %1

[proper trout]

what happens if i do

[grand folio]

water cooler

[proper trout]

i can just alt f4 out of the game

easy

[grand folio]

What are you going to do about the water cooler then

Your plan falls apart when you have to face the water cooler again

[proper trout]

alt f4

[grand folio]

Coward

[proper trout]

why call me that lol

[grand folio]

Maybe I shouldn't be telling you

I have the high ground in this conversation

[proper trout]

tell me, i wont explode no matter what the harsh truth it :3

does it have to do something with me disrespecting the %1

[idle plank]

what did you say about %1?

[proper trout]

1% is better

[idle plank]

...

[proper trout]

we all know these are all jokes lol

[idle plank]

||joke||

[proper trout]

ok

let me tell you one thing

[idle plank]

XD

[proper trout]

%1 is-

better now

[idle plank]

:D

[proper trout]

over %1?

just asking

[grand folio]

and this is why you don't disrespect %1

[proper trout]

why over %1 tho, im curious

[idle plank]

||%1 be like||

[proper trout]

oh i need to know what makes it so amazingggg

[idle plank]

hes so epic like rigby cat pee gif

What do you mean about reverse sprint bind?

isn't better just "Auto Run"?

Or what it is

[grand folio]

ok

just to be sure

this has his own tile mapper right?

[grand folio]

yes

[tiny folio]

is it open source rn

[grand folio]

no

[grand folio]

dumping textures

[grand folio]

might be going insane with some layout code

With debug boxes, you can see that each "invisible" object is a Layout

I've took some inspiration from CSS flexbox mathematical rules here

[sacred depot]

Ooo

[sacred depot]

oh damn

[grand folio]

Some similar stuff done on the main menu

[grand folio]

I'm looking forward to partially replace HScript with somewhat of a very non-reflective scripting class that can just always assume it's working within the game and not having to track sophisticated classes

I was unsure if I needed HScript to have that much power

But I'll lovely have it as a backup alternative

[sacred depot]

neat

[grand folio]

My criticism of this right now is that arguments are rigid and linear

// c:\GitHub\Undertale-Purple\source\backend\module\Module.hx

// ...
var definition = master.taskRegistry.get(taskName);
// ...
var taskArguments = parts.slice(1);

if (taskArguments.length > definition.arguments.length) 
// ...

var parsedArgs:Array<Dynamic> = [];
for (i in 0...definition.arguments.length)
{
    var argDef = definition.arguments[i];
    // ... parsing logic based on the fixed list in definition.arguments
}
// ...

I'm thinking of a decision tree, feels like a better way to parse arguments

[grand folio]

# Definition

A module is a text file with the extension `.module`. Function files are part of the hammer directory structure, highlighted:

assets/
    data/
    ├───hammer/
    │   └───modules/
        │   ├───module1.module
        │   ├───module2.module
        │   └───...

As with other files, the `modules` folder may also contain subfolders that can be used to organize modules. These subfolders must be referenced when invoking the module.

Within the `.module` file, one valid task is placed per line.

Comments can be added by starting a line with `//`.

A single backslash as the last non-whitespace character on a line indicates that the next line is a continuation of the current line.

# Invocations
Modules can be invoked in different manners.

## Invocation from modules
Modules can be invoked by other `.module` files. It is optional to add the extension.


call "test/test1"

writing docs

[grand folio]

i have the basics down

[wise crane]

wait wha-

that is insane

[grand folio]

say "Hello World"
call module2
$all[tag="player"] say "Found player"

Entity filtering work

[grand folio]

Having a hard time... I'll probably have to scrap this current iteration and think of a new DSL

[grand folio]

🤔

// Calls module2.module in the same directory, using the current Master's context
call module:module2

// Calls module4.module in a subdirectory, passing a context variable 'damage'
call module:subdirectory/subdirectory2/module4 context:{ damage:15 }

[wise crane]

that is a bit confusing

what does the module: prefix

there are more prefixes?

[grand folio]

I'm not at liberty to explain when I'm not even finished

[wise crane]

👍

There is the possibility of no longer using this thread since I've been exploring Kotlin these past few days

It's not absolute that I'm porting this project to Kotlin now but it's a possibility in the future
