Addressables help

[royal grotto]

for comparison

the problem really

is that

your builtin

seems to be pointing to the games folder

do this

[sage pine]

i clicked on view top level settings

[royal grotto]

basically on that oyu should put the same u put on LoadPath <custom>

[royal grotto]

build the addressables

and before u actually put it in the game

send the catalog.json pls

[sage pine]

built

[swift tinsel]

now it's correct

[royal grotto]

EXACTILY WHAT I SAID MUNIX

[royal grotto]

why doesnt unity let us change the builtin settings more easy?

btw

well its not of much help for you now

[swift tinsel]

template needs that

[royal grotto]

but any new group you create now will have the right settings

[sage pine]

good to know

[swift tinsel]

because seriously wtf

[royal grotto]

i think it already has the %ChangePath% thingie

[sage pine]

also have no idea how you would make a template that has everything ready to go for unity

[royal grotto]

tho i'll double check

[swift tinsel]

pretty easily

[sage pine]

https://tenor.com/view/kermit-demon-summoning-spell-gif-20055457

[royal grotto]

yeah most unity files are readable, so you can just search for something and replace

[swift tinsel]

most of the stuff is set up in text files, and when you generate the project, you just replace placeholders

[sage pine]

i understand the dark sorcery you both use

its okay.

OMFG

[royal grotto]

🙏

[sage pine]

i have a box.

LUL

[royal grotto]

God is great

lmao

[swift tinsel]

https://tenor.com/view/spongebob-worship-worshipping-now-bowing-gif-12297363

[royal grotto]

im not even religious

[sage pine]

hail satan!

[royal grotto]

either way im happy for you!

[swift tinsel]

all hail the box

[swift tinsel]

or that

[royal grotto]

same workflow for the particle acelerator btw

[sage pine]

https://tenor.com/view/van-free-candy-candy-funny-candy-van-gif-5788607

whats in the box?

candy...

i dont know what workflow means

but at least now, ill forget in 2 months how to do this

[royal grotto]

remember, same thing you put on the partName, you put on the addressables pair
and the addressables pair is always

• partName.json
• partName.prefab

[sage pine]

LUL i can color the box

that makes sense

and im gonna go through this post to make sure i write down the procedures of how to do this

maybe in 2 months munix has the template

[royal grotto]

i mean the template is not something that easy to do xD

[swift tinsel]

I sure hope it won't take that long lmao

[sage pine]

lol

[swift tinsel]

but right now I'm completely rewriting the current templates

so this will come after that

[sage pine]

well now i need to finish my linac modules

then figure out how i can upload them inidivudally

so theyre three separate parts

[royal grotto]

just make 3 separate prefabs

[sage pine]

no worries

thats what i was gonna do

[royal grotto]

withr 3 separate core part data

with 3 different partNames 🙏

[sage pine]

but ive gotta look at my models and decide what is going where

[royal grotto]

thast what i meant by easy after the first setup

[sage pine]

yeah now that i have a template

if i never close unity

itll work

LUL

[swift tinsel]

it was painful but it was worth it

[royal grotto]

it would be funny if it wasnt the truth

either way cya!

[swift tinsel]

good night finally lmao

[sage pine]

night!

LUL

[round lion]

Minecraft textures amirite

[sage pine]

@royal grotto Do I need to duplicate what I did with testpart with all of these or since they're the same part when they're assembled, can I place them together and use one collider for them?

[sage pine]

first test with this lets see how it goes

[royal grotto]

Create an empty gameobject on your part snd add s mesh collider

Dont forget to tick the Convex box on it

[sage pine]

this is how i have it, it all goes to the testPart

so testPart will get smesh collider? or will that go with the individual parts?

using capsule colliders right now

[round lion]

why are you making 5 seperate collision boxes?

[sage pine]

I thought I had to

[round lion]

you don't have to lmao

[sage pine]

hm

[round lion]

just put one of the col's and then the other 2 game object thingys from the video(s), then just add a mesh collider and click on convex

[sage pine]

so i can remove the colliders from the connectors?

https://tenor.com/view/denzel-washington-explain-it-to-me-gif-10559334

[round lion]

I mean yeah

you just need collider

[sage pine]

so one collider per part?

[round lion]

per part

yes

[sage pine]

and it makes it collidable

weird

[round lion]

it makes everything collidable

[sage pine]

makes sense but also weird

[round lion]

from said part

[sage pine]

and the collider should be a mesh collider?

[round lion]

yep

enable convex on it

[sage pine]

so what does that do now? it makes the entire part mesh collide

ohhh

[round lion]

this should be the structure

[sage pine]

so now it interacts with surfaces

[round lion]

dunno if it's needed

but It works for me

[round lion]

yeah

[sage pine]

oh weird

so the collider is a parent of all the little parts?

[round lion]

how

[sage pine]

dafuq is the box thing for?

[round lion]

it's just a random name for the mesh

[sage pine]

so what is in collision and what is in box?

[round lion]

okay 1 sec

[sage pine]

if box has a mesh, im confused now

[round lion]

this is for example another part

collision is just an empty gameobject

so is col_box_prim

[sage pine]

with no components?

[round lion]

yeah

and this is mesh

the "mesh" in mesh collider should be your .obj

for the part

[sage pine]

why the heck is collision even there if its just an empty game object?

[round lion]

don't ask me, I just used the tutorials from stick awhile back

[sage pine]

alright then lol

[round lion]

yeah it looks like it's working

[sage pine]

thank you! i had no idea, thats pretty dope

[sage pine]

@round lion @royal grotto when i export two parts, they just sink through the airfield?

[royal grotto]

the collider needs to be convex!

[sage pine]

they are

could it be an issue of the animation? since my animation isnt working properly, could that cause issues with the mesh?

also i removed srfAttach from the collector. could that be causing an issue?

[round lion]

are these meant to be 2 seperate parts in one? Why do you have 2 .json's? Also it may be your animation not being controlled (at all or properly)

wait no nvm

[sage pine]

two separate parts but they work together

ultimately ill have three parts

collector, waveguide, and electrongun

[round lion]

ah I see

well that could be a bit challenging

[round lion]

it can cause the animation to play constantly, not move the part

[sage pine]

yup i removed animation as i dont need it right now

ive got the animations, but not using them as it just yeets stuff lol

[round lion]

yeah you need to somehow control em

[sage pine]

yup

and that will be user based etc and a bit more than i need to do right now

right now is just testing textures

glad my animations work and when i get to that point ill get them functioning properly

[round lion]

wait so did the collision fix itself or smth?

[sage pine]

not sure

im about to test

to see if the animation was causing the issue

[round lion]

honestly I need to sit down and see how to make them work properly too lol

but anyways, I doubt the animation would be the issue

oh I know what it might be

on an earlier picture you didn't set the Mesh collider's mesh

[sage pine]

itll be good to know how to animate properly as itll be nice. especially being able to have a "right click > deploy" option

[round lion]

the animation part in unity is easy, it's hard implementing it

[sage pine]

you right

hm

i tested it wasnt the animation so im looking at the mesh

so where it says Mesh None (Mesh) i need to set that?

[round lion]

YEP

aa caps lock

[round lion]

but yeah you need to set it to the .obj of the part

I think

[sage pine]

hm

makes sense

[round lion]

find it in the project tab and then just drag it onto that

[sage pine]

will do

brb i appreciatg the help, ill let you know if it works

[round lion]

no problem lol

[sage pine]

worked

now they're coolidable

however you spell that

[round lion]

nice

[sage pine]

sort of

gotta tweak it but yeah it collides

[round lion]

that's good

[sage pine]

and the collider loses all texture when it loads into the game but in the vab it has texture

weird

[round lion]

I honestly got no idea

I have a similar bug

[sage pine]

does not setting the CoM etc cause issues?

oh

when i make these parts, they have to use 0,0,0 (x,y,z) when i prefab them otherwise it makes it unbalanced

[royal grotto]

wym by that?

[sage pine]

those are the two gameobjects that have the meshes attached to them

in game, the collectorbase is off center by -6

which causes it to be off balance

so is my theory

[royal grotto]

KSP2 Unity Tools gives you the CoM preview

that should be at the same position as the center of your mesh

[sage pine]

see?

so i need to move the com of that object

to line up properly

ahh

this makes sense

[royal grotto]

test it!

[sage pine]

rebuilding

i also need to make a paintmap that works properly. the one i made doesnt allow it to be transparent for some reason

but currently its all about...

https://tenor.com/view/loud-shredder-death-metal-intensifies-gif-18955511

metal. testing metallic textures

[royal grotto]

wait

[sage pine]

is the mesh messed up with its position?

[royal grotto]

your collision

[sage pine]

collision is completely blank

[royal grotto]

your colliders are in these 2?

oh ok

where are your colliders?

[sage pine]

yup its what worked and what yeetster showed me

[royal grotto]

[sage pine]

in the gameobject collector and waveguide

[royal grotto]

yeetster propapagating his wrong doings

[sage pine]

LUL

[royal grotto]

already told him the right way to do things but he just ignores me

[sage pine]

how should it be structured?

thegameObject
--part
--part
--------mesh

?

[royal grotto]

Basically something like this

partName (GameOject with partCoreData)
-model(Empty GameOject)
 -mesh(GameObject with Mesh Filter & MeshRenderer)
 -col(GameObject with MeshCollider)

the game needs that empty GameObject named model

also the Mesh Filter/Renderer should not be in the same Game Object as your collider

also the mesh and the collider should be a child of the "model" empty game object

[sage pine]

can you pin that?

[royal grotto]

sure

[sage pine]

be a good reference as i make parts

[sage pine]

i appreciate it ill rework this and test it and paste results

[royal grotto]

you can put the "col" as a child of the "mesh" if you want

also both the "mesh" and the "col" can be named whatever you want, i put it like that cuz thats how i name most of the times (if its only 1 mesh and 1 collider on the part)

[sage pine]

yeah its easy to name them mesh or col as it makes things uniform

and im all about uniformity so everyone is on the same page

makes it easier to debug stuff

[royal grotto]

as you should 🙏

[sage pine]

so heres where i get confused

mesh is attached to one of the objects

[royal grotto]

thast no problem

[sage pine]

then col is attached to mesh as a child

[royal grotto]

wait so every Collector_ is a mesh filter and renderer?

[sage pine]

the collector_ is the componenets

all of those make up the "collector" part

[royal grotto]

they dont have colliders right?

[sage pine]

nope

[royal grotto]

great

now, select the col

[sage pine]

the Collector has the collider currently

[royal grotto]

does it show green lines?

[sage pine]

model is empty

when i click on the collector it shows a grid

[royal grotto]

let me get into unity so that i can show u what i mean a sec

[sage pine]

i appreciate it lux

[royal grotto]

notice the green lines?

[sage pine]

yes

[royal grotto]

thats the collider

you should have the same green lines

but of them being the shape of your part

from what i can see you have a triangle there in the back

[royal grotto]

which doenst seem right

[sage pine]

yeah some random triangle thing

[royal grotto]

can you click on the col, and show me what components it has?

[sage pine]

i havent done anything with col yet

[royal grotto]

yeah makes sense

[sage pine]

collector has the collider in it right now

[royal grotto]

actually its one of its childs that has the collider

[sage pine]

oh

[royal grotto]

as you can see theres no Collider component there

[sage pine]

so collector is empty?

[royal grotto]

the collector has these 3 components

[sage pine]

i misunderstod what the collidr was

i thought core part data was the collider

[royal grotto]

nono xD thats all the data of your part

[sage pine]

but mesh is the collider

[royal grotto]

ok makes sense

well its off center as you can see

[royal grotto]

exactly thats what i was gonna say

tho

your mesh seems wrong then

for such a complex part

i'd advise you make a new mesh in blender

to put as a collider

basically just a simple mesh that you feel like will give u the collider you want

if you want, for now it can be just a cyllinder

that encapsulates all of the other meshes

[sage pine]

its the same mesh i used before

but i think mesh collider is causing issues

[royal grotto]

the mesh collider simply gets the mesh you feed it and and "shows it as green lines"

what does it look like w/o convex?

[sage pine]

oh weird

each mesh is way different

[royal grotto]

yup

tho, how does it look w/o convex?

a convex mesh is a mesh with a max of 256 vertices

[sage pine]

normal

thats weird

[royal grotto]

yeah

[sage pine]

no convex and it looks like its supposed to

[royal grotto]

but you cant really use non convex meshes in ksp

it would generate a LOT of lag

[sage pine]

lol

[royal grotto]

just imagine you're a collision program trying to detect either or not you're colliding with that thing

you'd have to check every step of the way

when you have a convex mesh you're either colliding or not, theres no inbetween

[sage pine]

yeah thats a lot to maths

[royal grotto]

on your mesh if you're on the center ur not colliding, but a bit to the side you are, but a bit more to the side you arent

etc etc

either way, unity tries to make your mesh convex

but due to the complexity it cant

thus you needing to make a mesh on blender for colliding

[sage pine]

this is just an empty cylinder?

thats what confuses me its the same thing as the waveguide tube

[royal grotto]

now try to turn that empty cyllinder into only 256 vertices xD

[sage pine]

cries

[royal grotto]

The convex option is like stretching rubber bands between the outer-most vertices. Just like Tiimmy said, Unity makes a more efficient mesh for objects like this rock example. You could also think of it as gift-wrapping your mesh. Irrespective of how helpful it is, primitives are nearly always going to be more efficient.

Basically the convex check mark will make a collider around your mesh without any 'indented' areas.

there's ways to make your mesh hollow tho dw

but you'll need a bit more blender magic for that

[sage pine]

thats what is weird to me

[royal grotto]

https://docs.unity3d.com/Manual/class-MeshCollider.html

Enable the checkbox to make the Mesh Collider collide with other Mesh Colliders. Convex Mesh Colliders are limited to 255 triangles.

[sage pine]

i build this cylinder the same way i built the other cylinder

[royal grotto]

the other has a cap in it doesnt it?

[sage pine]

nope

they're both hollow

[royal grotto]

either way unity is having trouble transforming that into only 255 triangles

[sage pine]

i have an idea as to why

[royal grotto]

maybe do to the complexity of the mesh

[sage pine]

its how its shaded

when i have it as...

[royal grotto]

oh thats no problem

[sage pine]

shaded

it makes it complicated

[royal grotto]

nono thats no problem

[sage pine]

when its just auto shaded its just like the other one

[royal grotto]

thats normals

[sage pine]

oh

[royal grotto]

not the actual mesh

that doesnt affect your mesh per say

just how the triangles are oriented

tho if you want to make your mesh hollow

you'll have to make the walls in 255 triangles

[sage pine]

this makes zero sense. literally the cylinder is a copy of the waveguide tube

[royal grotto]

you can divide that into various sections

[sage pine]

they're literally the same part

one of them i can have normal physics on, and the other one goes haywire

[royal grotto]

you can just use the waveform mesh then

[sage pine]

alright reworked those

what goes in col? also it has simplified the mesh so its not a billion vertices.

[royal grotto]

great

on the coll

you put a Mesh Collider

and set that simplified mesh to the mesh section

[sage pine]

so mesh gets a mesh collider AND col gets a mesh collider?

[royal grotto]

no, the mesh should not have a mesh collider

only the col

[sage pine]

k

so the col';s now have mesh colliders and theyre using convex's

do i need to set the mesh to a gameobject?

[royal grotto]

well

the simplified mesh no

unless you want to use it for something

as you can see now i thas the green lines

[sage pine]

col - Mesh Collider 
          Check - Convex
          Cooking Options: Mixed
          Material - None
          Mesh: Collector_Tube```

[royal grotto]

yeah

thats right

[sage pine]

then theres someting called simpilified mesh that goes into mesh?

[royal grotto]

tho you dont need to worry about the 2 in the middle

Yeah, you put the simplified mesh on the Mesh:

[sage pine]

ohh

i see

nope. i dont see.

[royal grotto]

yes, you put the simplified mesh there

tho

[sage pine]

what do you mean by simplified mesh. is it something i create, it should be made, or is it what ive already go tselected?

[royal grotto]

oh sorry that was your question xD

yes the simplified mesh you create in blender

[sage pine]

okay

[royal grotto]

just just a mesh that encapsulates your whole part

[sage pine]

so it wont be called simplified mesh, itll be called whatever i called it

[royal grotto]

that will be the mesh that the game will use for colliding with things

yes whataver you wanna call it

[sage pine]

okay i understand now haha

i was like "i dont see simplified mesh"

[royal grotto]

🙏

[sage pine]

that fixed it, but ive gotta simplify the other parts to the collider

thats why the graphical glitch happened

[royal grotto]

@round lion do things right

[sage pine]

has to do with the colliders

[royal grotto]

meshes are just meshes, they have no collider

meshes quite literally just "draw themselfs to the camera"

[sage pine]

yup

i undersatnd what they are, i just needed to understand the proper way to do it in unity

so you've explained it very well. i appreicate it. im sure ill have more questions down the road lol

[royal grotto]

feel free to ask them!

[sage pine]

ah

any guide on animating things properly

ive got my animations

i just dont know how to use them properly because when i use them, the triggers arent set up etc

[royal grotto]

1st thing would be to normalize your mesh size and position

[round lion]

hm?

[royal grotto]

ctrl+a on unity

[royal grotto]

look above, he fixed it

sorry @sage pine ctrl+a on Blender

THO careful

[sage pine]

do i need multiple mesh colliders for these parts? ie the ones in black

[royal grotto]

i mean you definetly can

[round lion]

hell nah I'm not dealing with simplified meshes

[royal grotto]

then no parts working for you

[sage pine]

ive already got the animations in unity from blender

[royal grotto]

game rules (literally)

[royal grotto]

hmm

honestly i do my animations on Unity

but theres a way to import them correctly

[royal grotto]

i dont know if i can give you the proper help on that

oh wait

[sage pine]

animations are working properly that ive imported, i just dont know how to add them to the object

[royal grotto]

well its easy

add a Animation Controller

to the model game object i believe

[sage pine]

over here right? the animation tab on the object

[royal grotto]

wait wait

select the mesh gameobject

[sage pine]

mesh is attached to collector_tube which is not what i want to animate

the animation will be attached to the magnets (pos and neg)

[royal grotto]

then add a Animator to the part you want to animate

or better

[sage pine]

makes sense

[royal grotto]

an Animation Clip

[sage pine]

any idea what trigger vfx animation script does?

[royal grotto]

havent played with that yet

[sage pine]

i figure its the script that allows you to do exactly what it says

[royal grotto]

its from KSP not from unity so yeah

[sage pine]

ill mess with it later

[royal grotto]

well, should do what it says but we have to test that

[sage pine]

this is what is generated when i add the Animation to the object

wejll when i add "Animator"

and i assume i add different layers and those control which animation happens?

I think this will just make the animation loop

[royal grotto]

a sec let me see what u sent

should be only 1 layer

you control the animation with

[sage pine]

ohh

[royal grotto]

the paramenters

[sage pine]

and then using the parameters changes how it animates etc

[royal grotto]

yup

in code you'll do something like

[sage pine]

makes sense

[royal grotto]

Animator.SetBool("parameterName", false);

or true

[sage pine]

ah

so thats how youll program it for user interaction

for it to do the animation

[royal grotto]

kinda yeah

[sage pine]

cause right now, since it has no trigger, its just going to go forever

lol

[royal grotto]

for your case you probably can use the game's provided ways

[sage pine]

yeah the idea is to make things deployable

since its science, i want it to be able to right click and have options for them to do the science

and animations attached to what they click

so they click "vaccuum seal particle accelerator"

and it does an animation

[royal grotto]

idk how science will work

[sage pine]

but thats a little bit away

[royal grotto]

so we'll have to wait on that

[sage pine]

yeah thats also why i havent tried tdo do anything with it yet

[royal grotto]

but you can make it just like solar panels and "Deploy"

for now

[sage pine]

that makes sense

obviously hvaent spent much time with the animations but thats down the road. at least i understand how to modify it and such

[royal grotto]

seems to be working tho! :D

[sage pine]

yeah it works but more to do to make it function better

ive gotta rework the animations in blender

and then figure out how to code the solar panels and deploy thing

unless you already have some script that i can use as a base?

[royal grotto]

thats easy (i think)

you dont need to do any scripting

its all done with Modules

[sage pine]

thats convenient

but i will have scripting

[royal grotto]

thats the whole concept behind modules

[sage pine]

ill have a GUI that looks like a computer screen

[royal grotto]

you have generic modules for what you need

[sage pine]

and lets the player use the GUI to modify behavior of the particle accelerator

buitttt again thats a good bit down the road

[royal grotto]

^

[sage pine]

today its about getting textures right

[sage pine]

ah

i need my textures in my blender file before i import them otherwise they don't work in game properly

but i did get this right

how they connect looks cool

[sage pine]

FYI: it's not a bug as to why it shows up black. If you don't UV unwrap your parts, the textures will show up black in game

[royal grotto]

yeah its actually just

that your mesh is all on 1 place of the Texture

[sage pine]

hm

[royal grotto]

if that 1 place is blue the texture will be blue

[sage pine]

hm

[sage pine]

@midnight torrent starting from here down is how lux help me get the gizmo's working as well as getting the addressables to work properly

[midnight torrent]

alr

[sage pine]

this is super important that you rename these to not be the full path. it will default them to being the full path. shorten it to whatever you've named your gameobject and your json

[midnight torrent]

where are they?

I GOT IT

[sage pine]

nice!

this thread is basically that tutorial plus more only problem is you have to search through it to find the fixes

lux has pinned some important stuff and as i remmeber things ill ahve him pin more

[sage pine]

@royal grotto so yeah ive got a few more things to tweak with basic textures, gotta make a paint map, and finish the electrongun model

but wanted to dabble with vfx a bit today

[royal grotto]

Then i recommend particle system as its what the game uses

You can layer them

[sage pine]

good to know

so a lot of experimenting should result in something useful

am i able to use this

[royal grotto]

Like 4/5 layers of particle systems isnt a bad idea

[sage pine]

or

[royal grotto]

Heh sure

[sage pine]

that was my plan was layering the laser in 5 layers

i was using line renderer and trail renderer to experiment with

[royal grotto]

It wont look great in ksp cuz the unitys line render aint the best but for now

[sage pine]

oh

[royal grotto]

That line render quite literally

Draws just a line

[sage pine]

yup

[royal grotto]

With no effects nothing

[sage pine]

dont mind me

LUL

im assuming this will work just like an engine

because the engine has a plume

but instead of it being plume for an engine, its just a laser beam

that will have heat etc

does your second video cover that part of the engine build?

used the same structure for the last part - the electrongun

but as this is vfx, does it go with the part its making a vfx for? or does it go separate?

[sage pine]

https://tenor.com/view/fire-the-laser-austin-powers-laser-surprised-shocked-gif-17302164

basically just shot a roll of toilet paper out of this thing

[royal grotto]

Lmao yeah thats what i mean for line renderer isnt the best

Unfortunately im the only one working on tools fo ksp2 atm so 😔😔😔

[sage pine]

this is particle system

[royal grotto]

GamePlay wise i mean

[royal grotto]

Oh god wtf the particle system also does that “rotate” thingie

[sage pine]

trying to figure out how to let it be a random seed but to also keep it within x,y,z spacing

[royal grotto]

[sage pine]

yeah

its epic

wait one

thats only one layer

there we go starting to hone this thing in and make particles

so each particle can create another particle lol

[sage pine]

particles go correct direction in unity (x axis) but in game they travel on the -z axis

is there something im missing with setting origins of particles up correctly?

parts in game are oriented upwards

think that the game is made for rockets

so you orient your parts as if they were part of a rocket

easy fix is to just rotate your particles

the right fix is to make your part be oriented up

@royal grotto ```cs
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class ParticleTrigger : MonoBehaviour
{
public ParticleSystem particleSystem;
public Light[] lights;
public AudioSource audioSource;

private void Start()
{
    // Perform any initialization or setup here
}

private void OnTriggerEnter(Collider other)
{
    if (other.CompareTag("Player"))
    {
        particleSystem.Play();

        foreach (Light light in lights)
        {
            light.enabled = true;
        }

        if (audioSource != null)
        {
            audioSource.Play();
        }
    }
}

}

this is a script I was working on to add a trigger to the particles. is this the correct way to do it or is there another way to do this properly?

using UnityEngine;
using System.Collections;
using System.Collections.Generic;

[ExecuteInEditMode]
public class TriggerScript : MonoBehaviour
{
    ParticleSystem ps;

    // these lists are used to contain the particles which match
    // the trigger conditions each frame.
    List<ParticleSystem.Particle> enter = new List<ParticleSystem.Particle>();
    List<ParticleSystem.Particle> exit = new List<ParticleSystem.Particle>();

    void OnEnable()
    {
        ps = GetComponent<ParticleSystem>();
    }

    void OnParticleTrigger()
    {
        // get the particles which matched the trigger conditions this frame
        int numEnter = ps.GetTriggerParticles(ParticleSystemTriggerEventType.Enter, enter);
        int numExit = ps.GetTriggerParticles(ParticleSystemTriggerEventType.Exit, exit);

        // iterate through the particles which entered the trigger and make them red
        for (int i = 0; i < numEnter; i++)
        {
            ParticleSystem.Particle p = enter[i];
            p.startColor = new Color32(255, 0, 0, 255);
            enter[i] = p;
        }

        // iterate through the particles which exited the trigger and make them green
        for (int i = 0; i < numExit; i++)
        {
            ParticleSystem.Particle p = exit[i];
            p.startColor = new Color32(0, 255, 0, 255);
            exit[i] = p;
        }

        // re-assign the modified particles back into the particle system
        ps.SetTriggerParticles(ParticleSystemTriggerEventType.Enter, enter);
        ps.SetTriggerParticles(ParticleSystemTriggerEventType.Exit, exit);
    }
}
``` this is the example from unity documentation

sure, tho the game already has that, i just dont know how to work w it
