[heady iris]

notice how each face is its own separate piece

if those faces were joined up, then you'd get a nice solid outline

but then the edges would not be sharp, since it would be smoothly blending the orientation of the faces

[mighty juniper]

issue is i imported them from the unity asset store as placeholders until i make proper models xD

[heady iris]

so yeah, highlighting looks good anyway

outline effects can be fiddly

here's the same effect done in Blender

you can see some funky parts where the effect breaks down

[mighty juniper]

yeah i see what you mean

[heady iris]

the HDRP outline effect I use duplicates the mesh and redraws it several times with slight offsets

very reliable, but also...probably not the fastest

[steady moat]

The best result I have seen didnt scale the model vertices to obtain the results but worked as a PostProcessing effect. Mind you, I never actually did an outline shader so I would not know if it challenging to do so this way.

[heady iris]

yeah, i cobbled it together from some tutorials and I only mostly understand it

[mighty juniper]

The same outline likely won’t work for the highlights either because it’ll just extend each face outwards and look silly

[heady iris]

oh yeah, you wouldn't want that for a highlight effect anyway

[mighty juniper]

Is there any way I can do the opposite? As in hollow out the centre

So it leaves a box of sorts

[heady iris]

unclear

[mighty juniper]

instead of the one to the left a box like this of sorts

[heady iris]

ah, you're highlighting the space to move to

you want it to appear sunken?

[mighty juniper]

this is what ive currently got

i just mean instead of a solid box, a frame essentially

[heady iris]

ah, ok

I would just make a separate mesh for the frame

[mighty juniper]

Oh yeah i guess that'd work

maybe this sphere idea would work better

not sure

[lusty zephyr]

making it red

[steady granite]

sorry for the delay, I am on Unity 2021.3.10f1 and TMP 3.0.6 which seems to be the latest available version?

[mighty juniper]

hm, im not sure

[thin aurora]

You should ask these type of questions in #archived-shaders , not here

[mighty juniper]

I didn't really consider it related to that initially, and i didnt know what else it fit into

[thin aurora]

Well it looks like a shader is applied, and I haven't seen any code yet

Not to mention you're more or less asking for an opinion rather than an actual problem 😄

[mighty juniper]

Well yeah, but you could say that about almost anything. And the description of the channel states ask questions and discuss, i know its not directly related to coding but i didnt see anywhere that fit better so i thought no harm in posting it here as no one was asking anything at the time anyways so i wasn't interrupting

[thin aurora]

Alrighty well if it's not a shader, #💻┃unity-talk would also be fitting.

[mighty juniper]

eh i guess so. I dont see why its a big deal though, i wasnt getting in the way of other conversations

[thin aurora]

I have these coding channels open alongside other channels, so if I see new messages I usually check them whilst working, should there be a question.

I understand it's not not as important now as if there were more conversations, but keeping it in the right channel is still easier for some people that might check these channels (also, the banner mentions general coding concepts in Unity, so it would be off-topic)

[knotty sun]

you might want to upgrade Unity to the latest 2021 LTS and see if there is a later TMPro version, from what I see in the change logs this may well have been fixed in a later version

there are a number of null ref exceptions fixed of which this looks like one

[heady iris]

that error suggests it found an object that it expected to not exist

that looks like a C++ statement, which is very interesting to see in the unity console, lol

[steady granite]

ok thank you I will look into it, upgrading Unity version is always a little bit daunting with a big project as it can break things

[heady iris]

comparing the result of .find() to the end iterator

[knotty sun]

It's a C++ assertion checking for null ref

[heady iris]

yeah

[knotty sun]

you should be OK as long as you stay within the same major version

backup your project first

[thin aurora]

Pretty sure reopening Unity fixes the problem too

[steady granite]

it does for the first time I enter play mode only sadly

[heady iris]

and it's specifically when you DontDestroyOnLoad the object?

[steady granite]

well, this is the line unity redirects me towards when I double click on the error...

[knotty sun]

I suspect it's a Marshalling problem. nothing you can do about it

[steady granite]

and disabling the DontDestroyOnLoad line seems to remove the error (obviously lots of more errors due to this requirement though)

[knotty sun]

and Scene Load/Reload?

Be interesting to see if you do an IL2CPP build and run that if you get the same problem

[steady granite]

oh, right just reloading the scene in the editor removes the error (still for one play mode enter still)

[knotty sun]

if it's consistent behaviour under given circumstances it's a bug

[steady granite]

I don't think this error occurs on builds, I have not seen these messages on the logs at least

[heady iris]

do you have Domain Reload / Scene Reload disabled down in Project Settings > Editor ?

iirc it's under a label like "Enter Play Mode Options"

[knotty sun]

good point, always a single point of failure

reload of static pointers

[heady iris]

this would be consistent with the issue going away for one play cycle after reloading the scene in the editor

[knotty sun]

indeed

[steady granite]

hmm, maybe unrelated but trying a IL2CPP build actually fails

[knotty sun]

oh, show error

[knotty sun]

different problem, your build environment is not set up correctly

[steady granite]

this? I used to enable it to have faster play mode enter but got lots of error after a while

[heady iris]

ok, so that's not the cause, then

i wonder if manually destroying this object as the game quits would fix the issue

[steady granite]

isn't OnDestroy called on scene destruction when quitting play mode?

[knotty sun]

Actually enabling Reload Domain may fix it

[heady iris]

I'd think it would ignore those settings if you don't have Enter Play Mode Options checked

[knotty sun]

It looks to me like an artifact from the previous Domain (i.e. Play mode) may be causing the error

[steady granite]

yes, this changes nothing

[knotty sun]

still greyed out

[heady iris]

The default is to reload the domain and scene.

[knotty sun]

need play mode options as well

[steady granite]

just tried all possibilities, does not seem to be related

[heady iris]

You can enable the Options checkbox and then uncheck the Reload Domain / Reload Scene checkboxes to disable those reloads

https://docs.unity3d.com/Manual/ConfigurableEnterPlayMode.html

[hollow kernel]

in a 2d space how do i make a projectile from the player at the direction the player is looking at

[knotty sun]

i'm thinking leave Scene unchecked, just the Domain Reload

[heady iris]

unity will perform both the domain and scene reloads if you don't explicitly tell it not to

[steady granite]

if "looking" means the player is rotated towards the target, you can use its transform.forward

[steady granite]

nope still have the same behavior

[hollow kernel]

okay i had added a velocity to the projectile with that but in game it gives an error that object reference not set to an instance of an object

this is my code

shootPoint = GameObject.FindGameObjectWithTag("shootPoint");
Bullet.velocity = shootPoint.transform.forward * bulletSpeed;```

and also the velocity is not added

[knotty sun]

which line is giving the error?

[hollow kernel]

the velocity line

[knotty sun]

so either Bullet is null or the Find is not working

[hollow kernel]

oh wait its the bullet

ok now no error but also no velocity

[knotty sun]

if in doubt Debug.Log it, see what velocity is being set to

[steady granite]

print shootPoint.transform.forward and bulletSpeed to check if any is 0

[runic kestrel]

Yo not sure if I'm in the right channel but I have a problem with a while loop. I'm not sure why but using an or operator in the while loop still requires both conditions to be true otherwise it won't stop and I cant figure out why

[hollow kernel]

shootPoint.transform.forward is 0

[knotty sun]

No!

[steady granite]

isn't Rigidbody2D.velocity meant to be modified via AddForce() only?

[hollow kernel]

nope

[heady iris]

unlockComb and Input.GetKeyDown must both be true for this loop to terminate

[knotty sun]

And 0 times anything is 0. QED

[heady iris]

having your forward vector be the zero vector is...interesting

[runic kestrel]

yea but why and is there a way i can terminate it with only one condition?

[heady iris]

sure, you just need to choose the appropriate logical operator

[hollow kernel]

well then now how can i give it a forward velocity

[heady iris]

state, in words, what you want to happen

no variable names

[runic kestrel]

okay wait i think i understand 😔

[knotty sun]

What I am saying is your assumption is incorrect. That statement as written will not require both conditions to be true

[heady iris]

a useful tip

[hollow kernel]

the shootPoint.transform.forward adds a z value which is useless for a 2d game

[heady iris]

the negation of A or B is not A and not B

it is not not (A and B)

it also isn't not A or not B

of course, you could also just say not (A or B) and keep it simple :p

[hollow kernel]

ok actually i need a break i will figure it out later thanks for the inputs

[heady iris]

oh, yes, if it's 2D, that won't be terribly helpful

you want transform.up, most likely

select the shoot point in the scene view and look at the colored arrows

red - X - right
green - Y - up
blue - Z - forward

[runic kestrel]

I got it working haha, i was too focused on the operator instead the actual logic of the loop

thanks 🙏

[bright token]

HFAmount is an ingame currency. I display it in the shop via text. If I change it from the HF script, attached to the text, the text changes accordingly. But If I change the HFAmount from this script shown: the text, nor the data, nor the HFAmount updates. I tried it all with Logging and this script doesnt change anything. Anyone knows what the reason is? (PullHero() is called when clicking a button to buy something)

[steady granite]

yes my bad using forward makes no sense in a 2D environment, use right or up depending on your scene and how you affect the rotation of your player

[knotty sun]

Bet you are using a reference to a Prefab script rather than a GameObject script

[bright token]

what do you mean with that?

my script is attached to a button in the scene

not a prefab

[knotty sun]

Are you expecting the change to HFAmount in that script to also affect data.HFAmount ?

[bright token]

yes

[knotty sun]

wrong

[bright token]

so that on the other script i can take it back

yea well thats why im here

how do I do it then?

[knotty sun]

HFAmount will be a value type not a reference type so values do not carry over

[steady granite]

I assume HFAmount is an int, changing the HFAmount value will not change any other value

[bright token]

yes it is, and what do i do then?

[steady granite]

so you have to manually reapply the new value to your data

[knotty sun]

do you know the difference between value types and reference types ?

[bright token]

i tried using SaveData(ref data) at the end of the if statement but it didnt work either

[bright token]

not exactly, i know what values are

[knotty sun]

then it is time to learn

[bright token]

id love to

[steady granite]

HFAmount--;
data.HFAmount = HFAmount;

something like that

[bright token]

yes but in that script i cant type "data.HFAmount"

it says "data doesnt exist in current context" and if i put "GameData data" into the parameters the whole thing doesnt work anymore

[steady granite]

or I love to use setter events to keep UI updated

[knotty sun]

very true. Is save or load called before PullHero?

[bright token]

both

[steady granite]

yes because data only exists in your Save/Load methods, you will have to keep a reference to it in your script if you want to modify it elsewhere

[knotty sun]

So cache GameData in that script then you can use it

[bright token]

and that goes how?.. xd

[knotty sun]

Game data localData;
void Save(GameData data) {
localData = data;
}
void PullHero() {
localdata.HFAmount--;
}

for example

[bright token]

hmm I see

i get it

but whats the Game data at first? you mean my class GameData?

[elfin tree]

how can I use .Find (or something else) to find an element in a list and call one of it's methods?
this is what i had: _bottles.Find( listBottle => listBottle == bottleToFindInList);

[knotty sun]

updated

[bright token]

is there a reason for the "Game data" written like that on the first line

or did you mean "GameData"

[knotty sun]

typo, fixed

[bright token]

ok :)

[steady granite]

what is _bottles? GameObject ot List<T>?

[elfin tree]

a list of "Bottle", an object/class

[bright token]

this didnt work either

[knotty sun]

Difference is GameData is a reference object, HFAmount is a Value object. You need to research the difference in behaviour

[bright token]

the output of saved data is still 55 even tho it shouldve been lowered

[steady granite]

do you have an error with this line? _bottles.Find( listBottle => listBottle == bottleToFindInList).Foo(); should work fine

[elfin tree]

Yes, but I want to call listBottle's method now

extra step 😛

[steady granite]

_bottles.Find( listBottle => listBottle == bottleToFindInList).YourMethodName(); ?

[elfin tree]

would that modify the one in the list or a copy of it?

but yeah that could be it

[steady granite]

Find returns the element corresponding to your condition, so you can call the function at the end of the Find() call

[steady granite]

the actual element, not a copy

[elfin tree]

thanks! 🙂

[hollow slate]

hi, how can i resize my ui components during playmode

i want to do this like file explorer

[steady granite]

like drag n drop from a corner to resize?

[hollow slate]

yes something like that

but i just need to resize just width

not height

to be more specific i want to resize scroll view

[steady granite]

What comes to mind would be :
-add a child game object at grab-able points
-add script on the child object implementing IBeginDragHandler, IDragHandler, IEndDragHandler
-start grab change parent anchor to left/right depending on child side
-during grab change parents width with mouse position delta
-end grab restore previous anchor

also maybe implement IPointerEnter/Exit and change your cursor to show you can change size when hovering this child

[hollow slate]

ok thanks

ill try that

[astral relic]

hello, i was wondering, unity animation editor can animate fields of scripts. how is that done ? does unity use reflection to change (lerp) the values or what, it should be sth else right ? otherwise that would be costy on performance

[heady iris]

I would expect it to be using reflection, since you don't have to recompile the game to change an animation.

[astral relic]

yea true

[honest sky]

is there a Rigidbody.gravityScale

or is it only rb2D.gravityScale

[honest sky]

Thanks 👍

[foggy dagger]

how do you make a list of all bools used in running scripts?

[manic chasm]

make an array

or a list

bool[] listofbools;

listofbools[0] = bool1
listofbools[1] = bool2
etc

[heady iris]

what do you want to do with this?

note that you can't, like, grab a pointer to a bool in another component

so that it updates whenever the other component's bool changes

[leaden ice]

you... you just don't

[foggy dagger]

i want to have a struct lets say SaveFloat and then everytime its used it adds it to a list in the game manager and saves it

[leaden ice]

Make a SaveData class that contains all the data you want to use and save, and always use that object during your game

[foggy dagger]

k thanks

[burnt echo]

Just wanted to say thanks for being my rubber duck, guys. Typed out a huge ass question, thought of something to try, it worked, deleted question. 😂

[heady iris]

lmao, it works

I've typed out several long questions and then just not bothered to send 'em

[pastel grove]

Hi all! I'm trying to generate a particle system purely through code, and it mostly works - except for when I try to assign a Light. Namely, the following simply does nothing; lights.light simply ends up being null. Does anyone know how it can be done, if at all?

[heady iris]

hang on, are you getting a NullReferenceException from the lights.light = new Light(); line?

or is lights.light null when you check it later

[pastel grove]

This.

[heady iris]

hmm, it says it wants a prefab

it might misbehave if you give it a non-prefab

[pastel grove]

I realize Light is a component and components aren't meant to be instantiated like this, but you can't exactly generate prefabs on the fly.

[heady iris]

oh wait, yeah, of course

that's why

<-- brain fart

[heady iris]

I guess you could create a game object, attach a light, and then assign the light component to lights.light

var obj = new GameObject():
var light = obj.AddComponent<Light>();

[pastel grove]

Guess so. Seems somewhat roundabout though - and what happens when I destroy the GO?

[heady iris]

well, then there lights.light will be null again

[pastel grove]

And if I don't immediately destroy it, then won't I end up with a surplus light in my scene?

Sure I could disable it, but then again - so much clutter!

[heady iris]

Is there a reason you can't just have a prefab?

[pastel grove]

I configure the hell out of it in runtime anyways, so not needing to maintain a prefab would be a lot cleaner.

Also, can you even prefab a component like this?

[heady iris]

sure -- you can assign a prefab to a field as long as the prefab has that component type on it

(or, more generally, you can assign an object in the scene as long as it has that component type on it)

[pastel grove]

Eh, yeah - not doing it in the scene.

I try to stay in code as much as possible.

So doing that in the scene would mean also prefabbing the particle system.

[wide pecan]

Hey everyone. Is there a way to call a function if a specific function in inheritance script was called? For example inheritance script has AddItem function and if this function is being called, derived script would call OnItemAdded function.

[heady iris]

well, if you do go with a prefab, yes

[pastel grove]

I'd like to avoid it if possible.

[heady iris]

what do you mean by "inheritance script"?

do you mean the parent type?

[pastel grove]

Call OnItemAdded in the base function.

[heady iris]

e.g.

class Parent { }
class Child : Parent { }

[wide pecan]

yeah

[heady iris]

I would do this:

[wide pecan]

I have several types of derived scripts and each of them has to do different things if the item was added

[heady iris]

public class Parent {
  public virtual void AddItem(Item item) { }
}

public class Child : Parent { 
  public override void AddItem(Item item) {
    base.AddItem(item);
    OnItemAdded(item);
  }
  
  public void OnItemAdded(Item item) { }
}

If each child type must implement OnItemAdded in its own unique way, then I'd make it an abstract function on Parent, and have the Parent's implementation of AddItem call it

[pastel grove]

Then override OnItemAdded in each derived class.

As @heady iris said.

[heady iris]

public abstract class Parent {
  public virtual void AddItem(Item item) {
    OnItemAdded(item);
  }

  public abstract void OnItemAdded(Item item);
}

public class Child : Parent { 
  public override void OnItemAdded(Item item) { }
}

if Parent can exist by itself, then make it non-abstract and just make OnItemAdded an empty virtual function

[wide pecan]

Thanks, I'll try this

Thank you so much. This works even better than expected. I expected unity to have something built-in function that activated right when the parent class is called but now I can control when to call OnItemAdded

[heady iris]

no prob!

[normal arch]

so im making a script that uses an animation curve and the animation curve changes dynamically, which is working, but not the way i want.
When i make an animtion curve it defaults to an ease-in-out curve, which i don't want, i want just an ease-out curve, is there any way to change this?

[leaden ice]

make a default curve variable

and just assign it to that in Awake or whatever

[normal arch]

but wont it just change back to an ease-in-out curve every time i change it?

[leaden ice]

wdym

how are you changing it

share some details

code etc

[normal arch]

this is the part of the code

jumpCurve = new AnimationCurve(new Keyframe(0, currentSpriteFloorHeight), new Keyframe(1, currentSpriteFloorHeight + 1));
        heightCurve = new AnimationCurve(new Keyframe(0, currentFloorHeight), new Keyframe(1, currentFloorHeight + 1));

[heady iris]

iirc you can control the handles on the keyframes, too

[leaden ice]

looks like you're defining the keyframes yourself

so it will make whatever curve you're giving it there

You should look into the other forms of the KeyFrame constructor:
https://docs.unity3d.com/ScriptReference/Keyframe-ctor.html

[normal arch]

ok

[leaden ice]

there are more parameters you can give

[normal arch]

i see there are 3 overloads

[leaden ice]

scroll down

yes

[heady iris]

hmm, how do you directly add a Keyframe to the AnimationCurve?

ah, https://docs.unity3d.com/ScriptReference/AnimationCurve-keys.html

[leaden ice]

Or https://docs.unity3d.com/ScriptReference/AnimationCurve.AddKey.html

[heady iris]

I guess you just make an array of keys, then set that property with it

[normal arch]

ok ty

[heady iris]

oh, duh

yes, go with the second AddKey overload :p

i thought it was a little weird that it didn't exist

[leaden ice]

You can contiinue to use the constructor too

it's fine

[normal arch]

so im not exactly that good with this kind of maths

so i dont even know what im doing with this

[leaden ice]

The tangent value is just the slope of the tangent

so 0 would give you a flat horizontal tangent

1 would give you a 45 degree upwards tangent
-1 is 45 degrees downward
infinity is a vertical line up

[normal arch]

ok

[leaden ice]

it's slope as in slope of a line (y = mx + b) where m is the slope

[normal arch]

like tan function i see

[leaden ice]

just a line function

Play with it a little you'll get it

I do wonder if I'm wrong and it's an angle 😆

not actually sure if it's slope or angle

but it's one of those

[heady iris]

it sounds like a slope

y = mx + 🅱️

[normal arch]

where i learned it was y = mx + c lol

[heady iris]

c for constant

that does make more sense

[normal arch]

i think its a slope though yeah

[heady iris]

i guess some people do y = ax + b

so it got mangled together

anyway, i always mess up ease in/ease out

if you want it to start fast and get slow, you want the t=0 keyframe to have a high slope

and t=1 to have a zero slope

[normal arch]

thats what i want yeah

im still messing about with it

[normal arch]

well i did it

i don't know how

but i did it

[heady iris]

I think I'm running into a situation where I need to "inject some dependencies"

so as I described yesterday, I'm replacing my fixed "health" and "stamina" (and etc.) stats with scriptable objects

i have an asset for each kind of stat

that's working pretty nice! but there's one problem

sometimes I want to refer to a specific instance of that Stat SO

for example, I want the default cost for blocking with a weapon to be stamina

but I don't really have any way to access that...

I need to use a specific asset to provide the default value for the "block cost" field

so that I don't have to manually configure that every time

[shell scarab]

You don’t have a way to access your stats!?

[heady iris]

That's the problem, yes 😛

It's actually almost never a problem. This makes it easy to have entities that, say, don't even have a healthbar

It might be too extreme of a design.

[shell scarab]

As far as I know, there are not supposed to be instances of an SO, or at least thats not how they’re supposed to be used. It’s supposed to minimize instancing so everything references one object.

Unless you’re talking about the literal object?

[heady iris]

well, by "instance", I mean the single object that's associated with a SO asset

[shell scarab]

Ah

[heady iris]

you can absolutely instantiate SOs

useful if you're doing...funky stuff

[shell scarab]

So how are you storing the stats in a way you cant access specific stats?

[heady iris]

just a public List<VitalValue> vitals;, where VitalValue is:

[System.Serializable]
public class VitalValue
{
    public Vital vital;
    [SerializeField]
    private float value;
    public float maxValue;
    public float decreaseTime;
    public float regenDelay;
    public float regenRate;

/* more stuff related to regeneration, calculating the current percentage, etc. */

and I have a dictionary of Vital -> VitalValue to look them up

This is very similar to what I was doing before

Vital was an enum

and I had a few named fields on the entity class

public VitalValue health;
public VitalValue stamina;

e.g.

[shell scarab]

Why cant you look up stamina?

[heady iris]

oh sure, I can

[unborn merlin]

guys
i have a problem

setting Time.timeScale to 0 and then to 1 resets a scene

[heady iris]

but I need to have the Stamina SO

[heady iris]

well that's odd

[shell scarab]

No it doesnt. That’s not where your problem is.

[unborn merlin]

i'm not kidding

[heady iris]

I'm gonna go muck around a little more. Thanks for chatting 😁

[unborn merlin]

i checked twice

[shell scarab]

Why don’t you make a list of SOs then, and on game start convert it to a dictionary?

[heady iris]

I do that already, yeah.

So this is only really relevant when I want to have default configurations for things

e.g. by default, a weapon's block should cost stamina to absorb hits with

most weapons will work this way

[shell scarab]

So have a reference to a scriptable object and default it to stamina?

I guess it’s hard without a lot of detail about your project.

[heady iris]

well, the default is the problem!

I'd have to get it from somewhere

[shell scarab]

Get it from the dictionary!

[heady iris]

with what key, though?

[shell scarab]

“Stamina”?

[heady iris]

i guess I could just key it on string name and then accept that I have a little bit of hardcoding

it wouldn't be that bad

yeah

it would be a very small number of places that actually care about the name

[shell scarab]

I mean no hard coding really

why would you have to hard code it?

[heady iris]

well, where does that string come from?

[shell scarab]

The scriptable object name?

[heady iris]

right, but I'd have to directly type that string into the code

I think that, at some point, it winds up being inevitable

[shell scarab]

No you don’t

[heady iris]

you have to identify the thing somehow

[shell scarab]

Well you do

But only once

Just have a public reference to an SO, and on start say if empty { SO = dictionary.stamina. That way if you want a different stat, it won’t replace it with stamina

[heady iris]

yeah

[shell scarab]

Defaults always gotta be hardcoded if it’s not a value type no?

[heady iris]

yeah, it has to live somewhere

it's just a matter of keeping it nice and concise

[swift falcon]

can anyone tell me how to destroy stop ?:
public GameObject stop;
Destroy(gameObject);

[normal arch]

Destroy(stop.gameObject);

that's it

you weren't using the variable name

[swift falcon]

ty

[heady iris]

or just Destroy(stop);, since it's already the GameObject

[heady iris]

possible teaching moment: why were you expecting Destroy(gameObject) to work?

it ~will~ run without causing any errors, I suppose 😛

[thorny onyx]

        if (moveup == true && movedown == false)

why is this moving instantly

[heady iris]

you may be expecting Lerp to smoothly move the object over time

this is not the case

Lerp smoothly picks a value between the start and end based on the third argument's value

0f = start, 1f = end

There are lots of packages and libraries that can do this lerping for you, which is probably what you were thinking of

[simple egret]

moveUp, moveDown - why do you have two? Can you move both up and down at the same time? You should only have one

[heady iris]

i imagine this is like how you ignore a move input if you're holding both forwards and backwards down

[thorny onyx]

yeah that was it

[lusty zephyr]

Basicly change it to Vector3.Lerp(startpos, endpos,Time.Time * (a float to speed it up if you want));

[heady iris]

note that this will slow down towards the end

[thorny onyx]

its a door operated by a button, i dont want the button to be mashed and break stuff

[heady iris]

every update, it will move a small fraction of the remaining distance

[thorny onyx]

i think itll be ok though

[heady iris]

ah, so it's a door

here's my suggestion:

[thorny onyx]

yeah i got it to work

[heady iris]

public bool open;
public float t;
public Vector3 startPos;
public Vector3 endPos;

void Update() {
  t = Mathf.MoveTowards(t, open ? 1 : 0, Time.deltaTime);
  transform.position = Vector3.Lerp(startPos, endPos, t);
}```

the door opens in 1 second

[thorny onyx]

hmm

if i have any more issues ill go with that

        {
            Debug.Log("move up");
            transform.position = Vector3.Lerp(transform.position, endpos,0.15f);

        }
        if (moveup == false)
        {
            transform.position = Vector3.Lerp(transform.position, startpos, 0.05f);


        }
    }
    public void toggleMove()
    {
        moveup = !moveup;
    }``` this works pretty well

what do the ? and : operators do again

ik theyre a shortcut

[heady iris]

it's the ternary operator

condition ? ifTrue : ifFalse

[heady iris]

this will be framerate-dependent, since it moves 15%/5% of the way to the destination every update

[thorny onyx]

oh yeah youre right

i can multiply by time.deltatime tho right

[heady iris]

that will make it move (a little less than) 15%/5% of the remaining distance per second

it's one of those things where it never quite reaches the destination

[candid forge]

i was wondering is there is a quick access of List<> variables through their attributes, kind of like

// pseudocode
class coordinate {
  int x;
  int y;
  int baba;
  ...
}

class implementation {
  List<coordinate> coordinates;
  coordinate a = coordinates.Find(coordinate.x == 1, coordinate.y == 0);
}

Something like this, i currently have a function with a foreach that looks through the list to find the object and return it and i'm wondering what would be a more efficient way of accessing, since this has O(n) efficency.

If there isn't what would be an efficient datatype compared to List?

[leaden ice]

There's no way to do this in a List without O(n) time

Use a Dictionary if you want to look things up by a particular key

[ocean river]

i have collision detection on a moving object, and whenever it goes into some corner, edge or similar hes clipping through. (walls and stuff)

is there a way to prevent that?

im using 3d

[leaden ice]

What does "have collision detection on a moving object" mean specifically

[ocean river]

box collision

and the others are mesh collisions or some rotated planes

and he can like walk through edges and stuff

[leaden ice]

What does "box collision" mean.

Sounds like you have a Collider on it

But that's only one piece of the puzzle

[ocean river]

box collider

its a gameobject

like super mario

[leaden ice]

You need more than just a collider for your object to not move through things

[ocean river]

rigidbody it has

[leaden ice]

Please show and explain your whole setup

What components it has, what movement code it is using, etc

[ocean river]

these are components of the rigidbody player, he is moving around like some classic game, with velocity and transform.translate.
the box collider should stop the player from walking against walls and walk on the ground, but in more complex maps that have small rooms and edges he just clips through.

well, now the problem is, he clips through these grey planes from behind and edges and like i said before,

is there a way to prevent that from happening, so he wont just walk through?

[muted helm]

Does unity give a preprocessor directive for if the program is running in build mode instead of the editor? I would assume that's what UNIT_EDITOR_WIN is but it isn't clear to me.

[hexed pecan]

Just UNITY_EDITOR should do the job

[muted helm]

Okay, thank you.

[fickle vigil]

hey,
im having trouble getting this level creator to work. it executes, but it's not putting an atlas PNG "atlas_#.png" in the output only the bytes file and the level text file.

there are 2 scripts involved im not sure which is creating the issues as no errors are produces also im quite new unity myself

[fickle vigil]

its from a template im using from the unity store "bizzy bee color by number"

[potent sleet]

dude did you even read the bot? no one gonna download textfiles tbh

[fickle vigil]

https://paste.ofcode.org/zUMaWBcg5tiVLXJLnQTd2u

like that?

[potent sleet]

this is a 1000 lines

you put both of them together?

why do you wanna make readability a chore lol

[fickle vigil]

no i didnt put them together

should i ?

[potent sleet]

you really like scrolling a 1000 lines to debug something ?

so no it should be split as much /often as possible to do so

[fickle vigil]

i found no bug

i metioned im new right?

[potent sleet]

no assumed you're not cause this is #archived-code-general not #💻┃code-beginner

[fickle vigil]

i was told to post here

sorry

@potent sleet this is coming up in vs code

CS0246: The type or namespace name 'Color' could not be found (are you missing a using directive or an assembly reference?)

my this is the issue?? i finally got itellisense working finding out its was a firewall issue so im trying to make up for lost time here too, this has been a long time unsolved problem for me

https://paste.ofcode.org/Awjz7knQEgDdzDxpKmzXiK

thats the other script

[potent sleet]

by whom

[fickle vigil]

someone in another channel

[potent sleet]

and Color should already be in UnityEngine directive

not sure which script or line that is so I can't say

[fickle vigil]

the second one i posted. the template is old could it have outdated dependencies or?

keep in mind i didnt write this script its part of the template i paid for

the creators are i guess not maintaining services to help the buyers which sucks

[gray mural]

@fickle vigil using System.Drawing;

[fickle vigil]

sorry im not sure what that refers to

[gray mural]

for this I guess

[potent sleet]

Color is already in UnityEngine namespace

[gray mural]

maybe

[potent sleet]

maybe ? it's an absolute fact

[gray mural]

not absolute

[potent sleet]

https://docs.unity3d.com/ScriptReference/Color.html

[gray mural]

for me it is not absolute though

yep then

[fickle vigil]

so should i just remove that namespace all together?

[gray mural]

why?

[potent sleet]

no, and considering you don't know anything about the script since you did not write , this is gonna be hard to debug.
Like i said you never shared the Line number of whatever script

[fickle vigil]

thats because it executes with no errors

[potent sleet]

you literally shared an error

[gray mural]

you sent one though

[fickle vigil]

its just doesnt produce the expect atlas png

[somber nacelle]

oh god, have you gone and done something dumb like mess with the compiler unity uses

[gray mural]

because it has errors

[ocean river]

can anyone help me, or tell me what explanation im missing?

[fickle vigil]

i dont think so

[somber nacelle]

do those planes have Mesh Colliders on them?

[somber nacelle]

then explain namespace BBG.PictureColoring; because file scoped namespaces are a c# 10 feature which unity does not support

[fickle vigil]

yeh thats from vs code not unity

[gray mural]

what?

what do you mean?

what do you mean to stop walking?

you can do it in the script, so that game stops when he walks somewhere?

or is it an issue of physic material?

[ocean river]

nope, box colliders

why is that so hard to explain... he should not walk into a wall

he should not walk through that wall

[gray mural]

ah

[ocean river]

the collider should stop the guy fromw alking
into
that

sorry

[gray mural]

are those walls actually planes?

i mean

plane

not cube

[ocean river]

nope, boxes

hm

[somber nacelle]

can you show the inspector for those plane objects?

[ocean river]

but i also use some mario odyssey map to test... and in edges or corners he can just walk through

right.

[somber nacelle]

also why are you using such an ancient version of unity

[fickle vigil]

everytime the word color comes up its showing a red underline in the creator working script

[ocean river]

because im making a game for the new 3ds

[gray mural]

it does not have rigidbody

[fickle vigil]

also vector2

[ocean river]

do all objects need one, like every?

[gray mural]

i mean not every

[somber nacelle]

no

[ocean river]

??

[gray mural]

ok, not every

[ocean river]

the boxes dont move

[potent sleet]

and yet you didnt mention which line of which script

[gray mural]

but you need rigitbody here

[somber nacelle]

if it doesn't need physics then it doesn't need a rigidbody. just a collider is exactly what you want for something static

[somber nacelle]

no

[heady iris]

well, you also need one if you want to get collision events

[fickle vigil]

the are multipe one sec

[ocean river]

but why does the guy slip through edge or walk through that plane, from behind?

[somber nacelle]

they have one on the player. it is not necessary to have one on these static objects

[heady iris]

ah, I see

[gray mural]

try to use rigidbody on those planes without gravity

[somber nacelle]

show how you actually move the player

[gray mural]

maybe you move it with transform.Translate?

[west elk]

Hi! I'm storing scores in an array and trying to get a new array with the positions of the scores. for example:
scores = [ 10 , 30 , 20 ];
places = [ 2 , 0 , 1 ];

Anyone with an idea on how I could do it?

[ocean river]

ah yeah, it happens with Vertical and Horizontal input, and transform.translate

[somber nacelle]

yeah transform.translate does not respect collisions

[fickle vigil]

Line 4 and 8 are the only exceptions threat are all color or vector2

[heady iris]

if you're getting an error on using UnityEngine;, then everything else is going to be hosed

[gray mural]

what is that?

you mean dictionary?

[somber nacelle]

i'd bet their error is due to them trying to use filescoped namespaces which i've already pointed out to them is not a feature supported by unity unless they've gone and messed with the compiler

[heady iris]

so you want to rank the scores

[west elk]

Nope, arrays. int[]

[west elk]

Exactly

[heady iris]

yes, I suspect that would do it

[gray mural]

what do you need to do?

[heady iris]

I guess I would sort the scores, then get the index of each original score in that new sorted list

(sort, then reverse, since you want high to low)

[gray mural]

like: 10 score => 3rd place, 20 => 2nd, 30 => 1st?

[west elk]

And then get IndexOf in the original array, right?

[heady iris]

Right.

[west elk]

Yes, this

[gray mural]

so use dictionary

[heady iris]

this will not handle ties, though

[heady iris]

this is about computing the ranks

[gray mural]

yes

[heady iris]

for ties, I guess I would remove duplicates first

[gray mural]

use dictionary then

IndexOf in dictionary

yrDictionary[score] => rank

[west elk]

Yeah I will handle that after, thanks! I feel silly for not thinking of that lol

[potent sleet]

did you read what boxfriend told you

about the namespace

your script can't compile with errors

[gray mural]

don't you just need to order all the scores?

32 => 1st place
25 => 2nd place
2 => 3rd place
1 => 4th place
...

[heady iris]

yes, which is what I described

[gray mural]

ok

then use LINQ OrderByDescending(x => x) method i guess

[gray mural]

i did not understand you before, I'm sorry

[potent sleet]

prob overkill

[somber nacelle]

OrderByDescending would probably be more appropriate

[gray mural]

oh yes

[ocean river]

sorry to ask, but whats an simple alternative for that, that does respect colls?

[heady iris]

you need to tell the rigidbody to move

rb.MovePosition or rb.AddForce, depending on how you're doing motion

or just setting rb.velocity

[somber nacelle]

using the rigidbody by either assigning velocity directly or using AddForce

[somber nacelle]

MovePosition will not respect collisions either, though having a rigidbody does make it a bit easier to check if it would collide with the SweepTest method

[heady iris]

It doesn't? I was under the impression that it did, huh

the documentation says that you teleport a Rigidbody by setting the transform's position

I guess that's just to let it interpolate

interesting, gotcha

[somber nacelle]

it's intended for a Kinematic rigidbody which won't collide with anything

[leaden ice]

My understanding is that it will cause a kinematic body to appropriately push things out of the way

[somber nacelle]

right, my explanation was worded poorly. a kinematic rigidbody will not be stopped by other colliders

[fickle vigil]

OK well I didn’t write that, so why are they selling a template on the unity store with that in it?

[fickle vigil]

Yep ☝️

[potent sleet]

which asset

[fickle vigil]

You mean which asset on the store to clarify?

https://assetstore.unity.com/packages/templates/packs/picture-coloring-color-by-numbers-game-153248

Hence “BBG” in namespace

[heady iris]

no

[heady iris]

^

line 8 is bogus in anything earlier than C#10

and Unity is on...C#9, if I recall correctly!

[fickle vigil]

I did a fresh install of everything multiple times and this script in the template never worked

[heady iris]

Yes. Because it's not valid.

You can't do that.

namespace Foo;

this is not valid in the version of C# that unity is using.

Change it to

namespace Foo { 
  /* code in here */
}

[fickle vigil]

Which am I changing Sorry.?

Unity engine? Or bbg.picture.

[heady iris]

oh wait, that's line 6, isn't it

https://paste.ofcode.org/Awjz7knQEgDdzDxpKmzXiK

[simple egret]

The one that has the error underlined

[heady iris]

namespace BBG.PictureColoring;

did you mean to make that a using statement?

[simple egret]

Nah it's probably the namespace declaration, seeing that it comes from the asset

[heady iris]

oh, it's from the asset itself

...why is it using file-scoped namespaces, though?

[simple egret]

Probably, but wtf is up with the formatting of this file

[heady iris]

that would never work in unity

i don't think this is directly from the asset

[hexed pecan]

Is that even a script for Unity

[fickle vigil]

so now I’m not getting the same errors I think I had something wrong with my.net, so I was doing some different installs there and now the debugger is working in unity

I will share the debug console information one second

[heady iris]

it sounds like you've done a bunch of random stuff

you should probably slow down

[simple egret]

• that asset is $75, and has a lot of negative reviews... I wouldn't have bought it myself

[fickle vigil]

Never mind I guess I can’t copy and paste the debug console

Doesn’t seem to be able to let you copy and paste

[analog echo]

yes you can

I dont know if you can in play mode

[fickle vigil]

It was the only one that isn’t based on colouring square pixels, which I don’t want. I’m trying to have a colour by number app that I can host artist pictures in

[fickle vigil]

So, when it says run in the bag on the left-hand side, it says select debugger.

It provides me with.net 5+ and .net core
.net framework 4x windows only.
C# godot
Then it seems to do nothing after that doesn’t matter which I pick I don’t understand what to do

[simple egret]

VS Code? The debugger plugin is deprecated and not supported anymore

[fickle vigil]

What is it you don’t think it’s directly from the asset?

[heady iris]

The script.

Did you create that file yourself?

[fickle vigil]

Yeah oh so you don’t use the debugger in code?

[simple egret]

You can't use it yep

[heady iris]

it sometimes works!

[fickle vigil]

Well, no wonder it’s not working then

[heady iris]

it's very wonky

[fickle vigil]

So everything I’ve been doing should be probably disregarded

[heady iris]

but the core problem here is that your script cannot work in Unity.

it uses a C#10 feature

[fickle vigil]

Right the core 10 feature being bbg namespace correct?

[simple egret]

Better use a supported code editor like Visual Studio 2022 or Rider, to be able to use the debugger. But that's not the issue here. Can't debug code that doesn't compile

[fickle vigil]

Right the core 10 feature being bbg namespace correct?

[heady iris]

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/proposals/csharp-10.0/file-scoped-namespaces

[fickle vigil]

I assure you it’s definitely 100% from the asset

[fickle vigil]

Do you want me to change it to “foo” BGG picture colour?

[heady iris]

no, I was simply using "Foo" as an example name

[simple egret]

File-scoped namespaces yes. Before C# 10 you had to do

namespace NameHere
{
  // Code goes here
}

But since C# 10 you can do

namespace NameHere;

// Code goes here

And the namespace applies to the whole file contents. It improves readability, as it decreases one level of indentation

But, Unity doesn't use C# 10, so you need the first way of doing things

[heady iris]

yeah, since you almost never put multiple namespaces in one file

[clear moss]

Is there any way to pathfind to the closest spot for the agent, but then stop?

[simple egret]

So whoever made that asset either 1. was on some experimental unreleased Unity version, or 2. not in a Unity project at all, and imported the Unity libraries in a standard C# project

[heady iris]

one thing that I noticed...

despite using the file scoped namespace

it's indented as if it wasn't

namespace BBG.PictureColoring;

    public class LevelCreatorWorker : Worker
    {
        #region Classes

        public class Settings
        {

I wonder if VS suggested that you switch to a file-scoped namespace

[simple egret]

VS won't as it's aware of the C# version being used, but VSC can be dumb enough to apply the wrong code fixes

[heady iris]

well, VS might also think it's on the wrong version :p

i used to have a problem where Unity wrote .csproj files with the wrong C# version...

9, ironically

but yeah, that's my guess

if you just turn that into namespace BBG.PictureColoring {

...and then add a matching closing brace all the way at the end

it should spring to life

[analog echo]

Sry for the late reply, here you have the error I get. If u need any else detail let me know.

Exception in transaction delegate, aborting transaction
System.NullReferenceException: Object reference not set to an instance of an object
  at NoticiasDBManager+<>c.<Start>b__1_1 (Firebase.Database.MutableData data) Exception in transaction delegate, aborting transaction

The code if someone wants to chek it out 🙃

[fickle vigil]

OK so after going into my back up, it is set up the other way that is correct, so yes, it must’ve suggested that but that still doesn’t change the fact that this has never worked as a function I will load from the back up and debug. Where should I be doing the debug then write in unity?

[heady iris]

Visual Studio will let you debug it.

[fickle vigil]

Ok let me do that see what it comes up with and then maybe it’ll be a lot easier to help me get this running

[simple egret]

Something bad happens in the .RunTransaction() lambda that causes this exception to be thrown. Most likely, mutableData.Value is not a IDictionary<string, object> implementor
Or, it's null as the exception actually says. Getting a .Count on it will throw that exception

[soft pike]

Hey guys I am currently working on a simple Dialogue System.
In a nutshell every Guest Dialogue will have an NPC response and vice versa.
However the inspector doesn't let me add elements after a certain point. Any thoughts?

[leaden ice]

Unity serialization has a depth limit of 7

[heady iris]

i would suggest breaking this up so that each state in the dialogue tree is its own SO

and you just link them together

[leaden ice]

Seems like not a scalable system anyway

[heady iris]

this will make you very sad very quickly, yes :p

[simple egret]

It's going to be a 180° answer but I would make a graph editor for this kind of dialogue system

[leaden ice]

Like that's just not readable

Also you won't be able to make branches that return to the main dialogue branch etc this way.

A graph representation is definitely the way to go

[fickle vigil]

Question, my Mac has file vault turned on with that be causing problems because I keep getting a message coming up that says certain files and bundles can’t be open because Apple cannot check it for malicious software and this is happening when I load up the project

[heady iris]

i need to look into making custom graph editors

[heady iris]

i have this problem when running other people's unity games, since Apple loves code signing

but I've never experienced it in the unity editor

[analog echo]

the weird thing is that the 1 time I call the void it gives that error, but when I call it another time it just starts working fine.

Also if I cange the code and save it, happends. But if I stop the play mode and start it again it works the first time I call the void, but anytime I save a script it breaks. (When I export as an APK it works on the 2 call)

[fickle vigil]

Do I just go in to privacy settings and allow each thing as it pops up and then reload it?

[simple egret]

Someone even made a sort-of programming language for that kind of thing and described it in their devlog. It had markers so characters would look at each other when talking, crazy stuff! I don't remember the publisher though, and I think it was closed-source

[fickle vigil]

It’s probably because I’m using that template

[heady iris]

maybe it also puts markers in the text to tell the game when to spawn items! [74] [74] [74] [74] [74]

ooh, prismatic shards!

stardew valley is a lovely game, but it can be very janky from time to time :p

[simple egret]

Oh, and it could also drive animations to represent emotions lol

All this from a text file a non-developer would create, and they made a parser in Unity

[soft pike]

I see. Didn't know that . Thanks for pointing that out

[soft pike]

Aah I will look into this

[soft pike]

Yeah you are right

[soft pike]

I understand. It's a school project so haven't really given it much thought

[soft pike]

Just curious. Why so?

[simple egret]

Can you log mutableData.Value?.GetType() before you cast it? Maybe it doesn't have a value. As for why it only starts working on the second run, not sure. Maybe the first call initializes something, and that thing is only ready at a later time?

[analog echo]

I opened unity, entered play mode and it worked, but when I start it again it just stops working and it logs Null

[simple egret]

Okay so your query there doesn't return any value

[analog echo]

but when it worked, it loged (Debug.Log(cantNoticias.Count)) it gave me 4

[simple egret]

So the first time this thing is called, the system isn't ready (?) and you get a null instead of your dictionary

[analog echo]

right, but when I opened the project I did the same as always and it worked

but now it doesnt

[simple egret]

I haven't dealt with Firebase from C# so I can't tell where the issue comes from

[analog echo]

Np, thx

[simple egret]

Anyone experienced with it lurking here, feel free to chip in

[analog echo]

So when I stay afk a Unity procces started and when it finished it worked, im going to try to screenshot it if I see it again

[analog echo]

these logs are from this:

Debug.Log(mutableData.Value?.GetType());
Debug.Log((IDictionary<string, object>)mutableData.Value);
Debug.Log(cantNoticias.Count);

[leaden ice]

I didn't write it, no idea.

[quaint rock]

would assume its a case of they had to stop somewhere, and ensure it does not get stuck forever if it hits a self referential data structure

[simple egret]

When it was first created, recursive functions were not a thing. So they agreed on a number they picked at random

[leaden ice]

Yeah probably a crude infinite cycle prevention mechanism

Also... to avoid the inspector looking like... well.. worse than that

[quaint rock]

if you need to go deeper there is a alternative now anyways

SerializeReference

[fickle vigil]

Soooo can you just run and debug the entire project because it’s asking me to open the folder but yet it won’t let me open entire folder it seems to want to only let me open a file and when I do it doesn’t allow me to debug

[analog echo]

Just deleting:

mutableData = null;

It worked

[simple egret]

Hm where did you have that lol?

[analog echo]

at the end of the lambda

it worked with another script so I just copied and paste xD

[simple egret]

Yeah that'll do it. Still no idea why it worked some time and not the other time. It probably never worked

[analog echo]

well, ty anyways 😁

[steady granite]

I'm not used to work with 3D, can you help with gimbal lock? Here's how I apply my rotation from mouse/stick to the camera:

    private void Camera_performed(UnityEngine.InputSystem.InputAction.CallbackContext obj)
    {
        Vector2 delta = obj.ReadValue<Vector2>();

        // Create Quaternion rotations for each axis based on joystick input
        Quaternion rotationX = Quaternion.AngleAxis(delta.y, Vector3.right);
        Quaternion rotationY = Quaternion.AngleAxis(delta.x, Vector3.up);

        // Combine the two rotations to get the final rotation
        Quaternion finalRotation = rotationY * rotationX;

        //camera.transform.Rotate(finalRotation.eulerAngles, Space.Self);
        camera.transform.rotation *= finalRotation;
    }

heres how it looks (or is that not what gimbal lock is?)

[leaden ice]

The typical approach is to have two objects in a parent/child relationship

• parent
  • camera

Rotate the parent object on the y axis only and the camera with local rotation on the x axis only.

[steady granite]

oh ok, I see how that would work but it seems weird to do it that way, if it works it works I guess, ty

and yes it does work 😅

[empty crystal]

Anyone know if there's a way to programmatically convert a texture (NOT Texture2D) to a sprite?

[haughty bison]

Unity directional light. 3d objects are lit up on one side but completely black in the other. Is there a solution or does unity just suck? Cuz I can't get anywhere with this garbage

On the other*

[shell scarab]

oh god no. Camera should be moved in LateUpdate.

so many small issues when just parenting it.

[shell scarab]

I don't rotate my camera with Quaternions not only because I don't understand them well enough, but because to my understanding they take the shortest path in rotation which is not always what you want to move because it'll rotate around the Z axis also. This is what I do:

rot = Vector3.Slerp(Vector3.zero, new Vector3(-delta.y, delta.x, 0), Time.smoothDeltaTime);
Vector3 newRot = _head.localEulerAngles + sensitivity * rot;
if (newRot.x > 89 && newRot.x < 180)
  newRot.x = 89.5f;
if (newRot.x < 271.5f && newRot.x > 180)
  newRot.x = 271.5f;

_head.localEulerAngles = newRot;

I do this on an input action, and have the camera follow the position and rotation in LateUpdate

[swift falcon]

No it's euler that does that and slerp is something for quaternions :3

[shell scarab]

can you elaborate more?

Slerp is not only "something for quaternions", there's literally a Vector3.Slerp method. It's for rotation.

and the vector3 shortest path vs the quaternion shortest path is different, so a quaternion's shortest path might wobble weirdly in my experience

I'm not sure that shortest route behavior is a thing with Quaternion.AngleAxis, but with .Slerp it definitely is, you can't force a direction with .Slerp to my knowledge.

#📦┃addressables

[swift falcon]

The issue with other axis' being affected from a lerp is a eular angles issue not a quaternion one that's because quaternions can't gimbal lock. And if I had to guess the slerp function for Vector3's is just a version that converts the eulars to quaternions and converts back

[shell scarab]

using solely quaternions I run into that issue. how is that possible then?

also don't guess

Vector3.Slerp is for interpolating directions, not positions.

https://docs.unity3d.com/ScriptReference/Vector3.Slerp.html

[swift falcon]

there's also a quaternion.slerp function what do you think that does?

[shell scarab]

quaternion.slerp interpolates rotations

[swift falcon]

it's doing the same thing as the vector one but instead vector3.slerp is converted to eular

[shell scarab]

it's not doing the same thing as Vector3.Slerp

[swift falcon]

💀

[shell scarab]

quaternions don't have a direction it's just a rotation

just 💀?

one interpolates directions, one interpolates rotations.

as far as I know these are different. I'll look at the unity C# reference right now to see. But now I don't trust you to explain to me how they're the same or different based on your response of only an emoji.

[swift falcon]

well I mean I am also busy

https://youtu.be/zc8b2Jo7mno 2:50 is where it shows this

[shell scarab]

I know what gimbal lock is but Vector3.Slerp is not rotation

it's for directions. Quaternions don't have a direction

[solar jolt]

anyone have any experience using beebyte obfuscator? had a couple of questions about it and there are no video's/debugging/resources to drill into for it.

[haughty bison]

So unity is trash then? Ok thanks.

[quartz folio]

No, the problem is you

[haughty bison]

Nope

Unity is just bad. The constant depreciation of things people find useful. Taking away good things it had.

[shell scarab]

lol what

[quartz folio]

Unity is one of the slowest at deprecating things out of any software I've used

[cold parrot]

someone is using non-LTS

[shell scarab]

I swear it feels like there's things that have been marked as depreciated for years and still not removed

[quartz folio]

If you want to make the backside of objects brighter, increase the environment lighting https://docs.unity3d.com/Manual/lighting-window.html and ask lighting questions in the #archived-lighting channel instead of a coding one.

[cold parrot]

well, years is what it should be

[haughty bison]

For one progrids isn't available anymore. And u would think at the very least they could have just made it part of unity

[shell scarab]

I agree

[haughty bison]

Thank you. And sorry. I didnt know

[quartz folio]

Progrids is still available.

[haughty bison]

Is it? Because I can't find it in package manager anymore. Except under my assets cuz I downloaded it before but even that won't install now.

I'll check again

[quartz folio]

Just add it via name com.unity.progrids

[cold parrot]

its a preview package

Ask your actual questions, as per #854851968446365696

[timid meteor]

Would this work to call a script from a gameobject called autohandplayer?

[mossy snow]

no, because it's searching by tag

[timid meteor]

ah I just realized that nvm XD

thanks

[timid meteor]

it would be gameobject.find instead correct?

[mossy snow]

yes, but be careful with that. Searching by name is awful and if there are multiple GOs with the same name, there is no guarantee which you might get back

[languid hound]

Anyone know why this SmoothDamp isn't.. smooth?

Don't know what I did but its fixed. Moves to 0, 0, 0 though

Jesus christ I didn't multiply forwards

Nope that doesn't matter

[quartz folio]

AFAIK because you are moving it to a position based on your current position. It's smooth if you have a consistent origin and a destination, not smooth if you do this thing where you have a = SmoothDamp(a, a + b, ...)

a = SmoothDamp(a, b, ...) would work fine

If you for example smoothdamped your direction vector, and added that to your position it would work fine

[languid hound]

I see that makes sense I'll try that now

Worked perfect thanks!

[solar jolt]

this one is a mix of buildpipeline and shaders, is there a way to avoid compiling any shaders for a build, i.e. avoid my always included shaders?

I want to build a console window but shaders appear to still be added

[late gyro]

what is the best way to do tile collisions? currently using custom physics shape, but it's so much god damn work

[steady moat]

Use AssetBundle which does not include the shader.
Alternatively, look into https://docs.unity3d.com/ScriptReference/Build.IPreprocessShaders.OnProcessShader.html

Do you use the "new" input system ?

[topaz gate]

I have both enabled

[steady moat]

Are you sure you correctly enable the Active Input Handling to Both ?

[topaz gate]

I am not sure

[steady moat]

The setting should be in Player Settings.

Project Settings -> Player -> Other Settings as I read on Internet.

Is gameObject.Find("Stuff") so bad that it's illegal, or is it fine to use it in functions that happens every now and then? 🤔

[lean sail]

Is there a general guideline for when I should be putting scripts on the player vs when it should be on an object? For example, I want a script for buttons controlling a spaceship, the player is on the spaceship.
There will be a trigger for when the player is in the ship and then the buttons themselves will need to affect the ships velocity, which leads me to think the script should be on the object.
But I also need to account for player input, which makes me think it should be on the player
Basically should the player detect the box trigger, or should the box trigger detect the player?

[solar jolt]

You can approach this several ways.
One way is if this is a script that can alternate from one ship to the next then make it ship dependent otherwise you could have it as an input profile that you can switch on and off the player.
So you have one profile for normal input and one for ship input, technically you could use this approach for all forms of input, i.e. switch to normal 3rd person/1st person input when not in a vehicle, switch to ship input when in ship, switch to land input when in land vehicle.

[steady moat]

Neither of them. The player should be an "Avatar" as the spaceship. What you want is interface the control of the ship and the player.

In other words, you should be able to control the ship without the usage of input. It can become handy to follow such paradigm in the event where you have multiple target (Avatar, Spaceship, Menu) and source (AI, Cinematics, Player, Multiplayer, Online)

[lean sail]

Thanks this cleared up a lot even for simpler interactions

[lean sail]

Im slightly confused what you mean honestly, i understand the idea but how does this cause the ship to be controlled without input?

[steady moat]

You should always other means to find GameObject. The usage of Find("...") breaks easily whenever you rename or reparent object. It can be a nightmare to maintain whenever your project starts to take complexity. Also, this is not an efficient way in term of performance.

Reference is a good way to manage those type of needs. It can also be done with GetComponent if needed. Tag, Singelton, ServiceLocator or Depency Injection are all valid ways to operate.

[steady moat]

The ship most be interfaced with the concept of input. It can comes in the manner that the control of the ship is completely externalize or by the usage of an interface.

This is the Dependency Inversion Principle.

[solar jolt]

a crude way of having this work is the player has an input interface

{
    void WKeyInput();
    void AKeyInput();
    void SKeyInput();
    void DKeyInput();
}```
then when you create different inputs they can implement this interface and this can be inserted into the player as a 'ShipInput', 'LandVehicleInput', 'FirstPersonInput'
```public ShipInput : IInput
{
    void WKeyInput()
    {
        // Move Forward.
    }
    void AKeyInput()
    {
        // Rotate Left.
    }
    void SKeyInput()
    {
        // Move Back.
    }
    void DKeyInput()
    {
        // Rotate Right.
    }
}```
```public Player
{
    [SerializeReference] IInput input;
}```

[lean sail]

Oh I see, thanks for the image! Im still new to unity but i know a good amount of c# so Ill look more into this

[steady moat]

The principle comes from the SOLID principle which you probably heard of.

[lean sail]

Yea ive heard of it but its been awhile

[blissful frost]

hello i am trying to shoot raycast out of a car gameobject can anyone direct me to some code or somehow explain how to shoot them out(im new to raycasts)

ping if you can help

[lean sail]

Thanks for the example code too! I'll experiment with this on the player

[solar jolt]

this is extremely abstracted, you would still need to implement the approach to firing the interface methods either via old input system or new input system, so don't forget that.

[lean sail]

Look at the 3rd code block for a very basic example.
If you wanna see the raycast you can draw them with Debug.DrawLine(start position, end position, color, duration)
https://docs.unity3d.com/ScriptReference/Physics.Raycast.html

[blissful frost]

how do i make it shoot out rays in other directions not just up and forward

[lean sail]

the input is a vector, you can choose the direction by just making a new vector3(x,y,z) direction. If you want a dynamic direction like the forward direction of the car, you can just take the objectName.TransformDirection(Vector3.forward)

[blissful frost]

how do i make the raycast start a little more up?

[solar jolt]

My implementation of OnProcessShader doesn't appear to fire when running build

[blissful frost]

^

[solar jolt]

pretty sure you can just do objectName.transform.forward

[lean sail]

Lol I actually used transform.forward in one script but TransformDirection(Vector3.forward) in another, oops

[lean sail]

in the example code, transform.position is the start position. its a vector, so you can add to it

[blissful frost]

how would i do that?

Vector3(car.transform.position.x, car.transform.position.y + 3, car.transform.position.z)

i tried this but now worky

[lean sail]

Do you know vector math or are you asking specifically about doing it unity?

[blissful frost]

in unity

transform.position(car.transform.position.x, car.transform.position.y + 3, car.transform.position.z

hb that

with a ending parantehses i forgot

[leaden ice]

You're just kinda making up syntax as you go eh

[lean sail]

U can just add vectors in unity with the + symbol the same way u add numbers

[blissful frost]

i need to know how that would like in code

i not good at c# learning sytax as i go

[solar jolt]

I lol'd

[leaden ice]

transform.position += Vector3.up * 3;

[lean sail]

Like
Vector3 offset = new Vector3(x,y,z)
then plug in car.transform.position + offset

[lean sail]

definitely have been there in desperate moments, just writing random words in hopes its a function

[blissful frost]

would i say like Vector3 offset = new Vector3(0,3,0) if im trying to be three units higher?

[blissful frost]

yep

[lean sail]

yes thatll work but also i just wrote it as a new variable to show it, there are still other ways to add like said above Vector3.up * 3;

[blissful frost]

Now how would i make it slighty downwards

[lean sail]

That is left to the reader as exercise

[solar jolt]

time to do it the fun way Vector3.up + Vector3.up + Vector3.up

[blissful frost]

so do you guys know how to make it go downwards

[leaden ice]

Think about it for a minute

[solar jolt]

we'll wait

[leaden ice]

I think you can figure it out

[lean sail]

I believe in you, if up is positive then...

[marble halo]

So I'm trying to make it so you can pan the map around by clicking and dragging, but for some reason it pans in the x and y axis rather than the x and z axis.

    {
        PointerEventData pointerData = (PointerEventData)data;
        Vector2 position;
        RectTransformUtility.ScreenPointToLocalPointInRectangle((RectTransform)canvas.transform,pointerData.position,canvas.worldCamera, out position);

        camView.transform.position = canvas.transform.TransformPoint(position);
    }```

how do i make it pan in the x and z axis?

[blissful frost]

im talking about rotation

not if its going up or down

how do i make the ray shoot out at an angle from the origin

[lean sail]

I would really recommend you look at vector math. the vector is the direction

        if (Physics.Raycast(transform.position, -Vector3.up, out hit))
            print("Found an object - distance: " + hit.distance);

[leaden ice]

It goes in whatever direction you tell it to

[blissful frost]

ik

[leaden ice]

Vector3.down exists BTW

[blissful frost]

but how do i tell it to go at a certain angele forward

[leaden ice]

What certain angle

What does "certain angle forward" mean

You have to be specific

[blissful frost]

like that

like forward and down 60 degrees

[leaden ice]

I have no idea what that picture is showing lol

[lean sail]

Ok good you have drawn what i was going to explain, all those lines you have drawn are vectors, they are not angles

[leaden ice]

Anyway you can always rotate a vector by multiplying a quaternion with it

If needed

[blissful frost]

how

[leaden ice]

By multiplying a quaternion with it

With the * operator

[blissful frost]

agian i very new with with syntax and need a example code

[leaden ice]

q * v gives you v rotated by q

Literally with * like I said

[blissful frost]

what is q?

[leaden ice]

A quaternion

Like I said

[blissful frost]

bro

[lean sail]

Before getting into that honestly just experiment with plugging in random values lol. Quaternions are hard to understand at first, and honestly i dont think you know vector math to begin with

Like see what happens when you use idk (-1, -1, 0) as a direction

[blissful frost]

car.transform.TransformDirection(Vector3.left) * quaternion makes a lot a sense

[leaden ice]

Doesn't work that way

[blissful frost]

ik

thats y i ask for more explantions

[leaden ice]

Quaternion goes first

[blissful frost]

not just thats what i said

[leaden ice]

Vector second

[blissful frost]

what is quaternion??

how would i describe it

[leaden ice]

It's just a variable that represents a rotation

That's all

[blissful frost]

how would i represent like 45 degress down?

[leaden ice]

Like a vector3 can represent a position

"down" is not a rotation

[blissful frost]

vecotr3(x,y,z)

[leaden ice]

So that doesn't make sense

[blissful frost]

hb a quternion

[leaden ice]

Quaternion.Euler(x,y,z)

Where those are angles around those axes

Or use Quaternion.AngleAxis

Where you provide an angle and an axis

[blissful frost]

Quaternion.Euler(x,y,z) * Vector3(x,y,z)

explain how to do that

[lean sail]

Honestly quaternions are going to confuse you too much right now. I would really just say experiment with plugging in random vectors to see where the raycast ends up.

[blissful frost]

side view btw

[blissful frost]

ok

[lean sail]

Like when you say at an angle, do you really need it at a specific angle or do you want it just angled down

[blissful frost]

angled down

not fully facing down but at an angle

[lean sail]

yea just go for random values, look at quaternions after you actually understand vectors

[blissful frost]

how do i put in thos random values?

            print("Found an object - distance: " + hit.distance);
            Debug.DrawRay(car.transform.position + offset, car.transform.TransformDirection(Vector3.forward) * hit.distance, Color.yellow);```

[lean sail]

Think of random values and put them into a vector

[blissful frost]

thats my code for forward raycast how would i make it go down

just pot me in the right direction

[lean sail]

idk if you saw but someone corrected my code i provided, you can just use car.transform.forward instead of what i wrote
For the vectors, the docs say

Vector3.forward
Shorthand for writing Vector3(0, 0, 1).```

Vector3.up
Shorthand for writing Vector3(0, 1, 0).

Really, just look at vector math already itll make sense

[blissful frost]

_rotation = Quaternion.Euler(car.transform.rotation.x, car.transform.rotation.y-1, car.transform.rotation.z);

_rotation * car.transform.TransformDirection(Vector3.forward)```

does this work?

[plucky karma]

car.transform.rotation is not a euler angles. Use localEuler.

What are you trying to do here? Why not just cam.transform.forward?

[solar jolt]

Here I got ChatGPT to answer it for you

If you want to get the resulting forward direction without actually rotating the object, you can simply multiply the current forward direction of the object by the rotation quaternion that you calculated. Here's an example code snippet:

// Get the current forward direction of the object
Vector3 currentForward = transform.forward;

// Calculate the new rotation by rotating the forward vector 60 degrees to the right
Quaternion newRotation = Quaternion.Euler(0f, 60f, 0f);

// Calculate the resulting forward direction by multiplying the current forward direction by the new rotation
Vector3 resultingForward = newRotation * currentForward;```
In this example, we first get the current forward direction of the object using transform.forward. We then calculate the new rotation quaternion using Quaternion.Euler, just as we did in the previous example. Finally, we calculate the resulting forward direction by multiplying the current forward direction by the new rotation quaternion using the * operator. Note that this operation does not actually rotate the object - it just calculates the resulting forward direction as if the object had been rotated.

[blissful frost]

i already asked chagpt and it answered my q

[lean sail]

my fault for that last part 😔, i got that from online awhile ago and never realized theres a .forward

[solar jolt]

Anyone got a solution for excluding all shaders from a build when firing UnityEditor.BuildPipeline.Build()?

[shell scarab]

How would I stop my camera from inverting when going upside-down? I'm setting the transform.forward to a vector pointing at another object to look at it, and I want to allow the camera to go upside-down.

This doesn't seem to happen with other objects when I use transform.forward = dir, so it leads me to believe it's something built into the camera component doing this.

[lean sail]

When you want it to be upside down, without rotation, where is the camera in relation to the player?

[shell scarab]

at a fixed point

[plucky karma]

Consider using Vector instead of transform. E.g. Vector3.forward.

(So as long as your camera doesn't rotate 😄 )

[shell scarab]

what do you mean? can you give me an example?

[plucky karma]

Vector3.forward returns a value of (0,0,1)

[shell scarab]

I don't think you understand what I'm doing.

I'm setting transform.forward to a direction vector.

[lean sail]

Are you changing only the x or z axis?

because y value would cause it to invert, x going 180 would be upside down

[shell scarab]

I'm literally doing transform.forward = direction;

[shell scarab]

yes exactly. As the x rotation approaches and passes 180, Y rotation gets set to 180.

when it goes back, Y gets set back to 0

I'm not doing this in my code and transform.forward doesn't do this on other objects, so it leads me to believe it's some built in thing in unity's camera component doing this to prevent cameras from going upside-down when rotating, which I want to allow.

[plucky karma]

When you say that your camera "inverted", what do you mean by that?

[shell scarab]

this

I'm not sure if inverted is the right word.

[plucky karma]

You're facing a gimbal lock.

[shell scarab]

well, why doesn't that happen with other objects!?

[plucky karma]

What does your direction value looks like?

[lean sail]

I dont think its a gimbal lock, i could be wrong but i think thats camera specific

Are you using a cinemachine camera?

[shell scarab]

no it's gimbal lock I'm a dumbass.

[lean sail]

🤔 howd u manage that

[shell scarab]

because that's what happens when you get gimbal lock and i thought it wasn't happening on other objects because I was like I TESTED IT but I literally had a script on that object that was setting the y value rotation to 0 every frame, so ofc it wouldn't change to 180
