strange, maybe on the event system you can see whats being detected if any at all, new one kinda sucks at telling you whats happening only tells you on click

#

rigidbody (kinematic I think) or translate, each has its pros and cons
if you mean timescale you can use unscaledDelta

I think... my game window was bugged. I closed "game" and "device simulator" and reopened "game" and now everything seems to be working.

rich adder
#

as long as its working now though ig lol

Thanks, this worked.
The animation of my character is slightly skewed though, so when I walk forwards it actually ends up walking about 20 degrees off from 12 o'clock

wintry quarry
#

it could be an issue with how your scene/control system is setup or it could be an issue with your character model

#

This is when holding W (ignore the random things in the scene, I'm doing some practice stuff for class)

#

The character does rotate with the camera, but it's off

#

And it's the animation itself that moves the character, not any script I've made (which I don't like, but that's what we were taught thus far)

sprite editor lets you change pivot of a sprite so if you want to add the tip instead it'd be easier

silver fern
#

oh

silver fern
rich adder
#

if you click the sprite and bring it the asset importer window you should see sprite editor.. unless its Unitys sprite then idk how lol

silver fern
#

ah damn

#

yeah its just a diamond shape I drew with the editor

how to fix this?

#

can I invoke a unity event that was defined in another script?

#

directly invoking it doesn't seem to work, is there a way to do it?

grand snow
#

yea UnityEvents can

#

event fields cannot

#

an event can only be invoked in the owning class but a UnityEvent is just a class that re creates event functionality so no restriction.

silver fern
#

how do I do that then? do I have to use like a get method to get a reference to the event from the script that defines it?

grand snow
#

call .Invoke() on it

silver fern
#

that's what I'm doing but the event is not getting invoked

grand snow
#

it surely is

#

you must not have subscribed to it or its not the event you think it is

rich adder
grand snow
#

or use a ✨ debugger

silver fern
#

I put a print in the method that is supposed to get called but it does not print, and I have subscribed it correctly in the editor

#

wait do I have to subscribe it in both scripts?

grand snow
#

if you use a debugger and have breakpoints where you Invoke and what you expect to be called then you can actually know whats happening

#

a subscription in the inspector or in code is fine

polar acorn
silver fern
#

I mean, I have it subscribed for the script that creates it but not for the second script that also invokes it

polar acorn
#

You're going to need to be more specific

rich adder
#

trace your code and see where it goes wrong 💫 debugger

polar acorn
#

Like, what is it subscribed to? What is the "other" script in this context?

#

And yes, the debugger will let you step through every line one at a time

silver fern
#

that's not the issue, I wanted to know how to correctly invoke a unity event from a script that does not define that event

grand snow
#

I told you

#

you must have some other problem or be mistaken
use a debugger to debug this properly instead

polar acorn
silver fern
#

no I mean, I am most certainly doing it incorrectly

grand snow
#

Then share some !code if needed

eternal falconBOT
grand snow
#

Is the event on the correct instance that you expect?

#

if the subscription is done in the inspector, is it still valid when you Invoke the event?

silver fern
#

if I just do eventName.Invoke() in another script it tells me eventName does not exist in the current context

grand snow
#

you need to retrieve it from the instance of the class...

rich adder
#

you need a reference to it

grand snow
#

GetComponent<MyCoolClass>().myDumbEvent.Invoke();

rich adder
#

script doesnt magically know about it

grand snow
#

what are you doing 😆

polar acorn
silver fern
grand snow
#

share some code if you need further help because you seem very confused

silver fern
#

so that connection needs to be hardcoded, I was hoping to avoid that somehow

#

ok one sec

grand snow
#

if you want some event that exists "globally" then use a static event:
public static event Action<Debuff> OnDebuffAdded;

#

Here you should avoid UnityEvent because there is no benefit

silver fern
#

maybe my whole approach is just dumb

grand snow
#

I think you forgot about object instances

silver fern
#

in this case, the buff is supposed to change the basic attack to a different one while the buff lasts, so I thought it would be best to call the unity event and have the attack script listen to that and switch attack types when it happens

grand snow
#

something like this could make sense

#

e.g.

public void AddDebuff(Debuff debuff)
{
  debuffs.Add(debuff);
  debuff.OnActivate += OnDebuffActivated;
  debuff.OnDeactivate += OnDebuffDeactivated;
}
#

in this example we subscribe to the events on that specific instance

#

presuming these are something like event Action<Debuff>

silver fern
# 
using UnityEngine;
using UnityEngine.Events;

public class CounterShockEffect : EffectObject
{
    public override EffectAlignment EffectAlignment { get; } = EffectAlignment.Buff;
    public override EffectType EffectType { get; } = EffectType.CounterShock;
    public override int EffectAuthorityLevel { get; } = 1;
    public override float EffectDuration { get; set; } = 1;

    public UnityEvent onCounterShockOn;
    public UnityEvent onCounterShockOff;

    public CounterShockEffect(float effectDuration = 1)
    {
        EffectDuration = effectDuration;
    }

    public override void StartEffect(MonoBehaviour mono)
    {
        onCounterShockOn.Invoke();
    }

    public override void StopEffect()
    {
        onCounterShockOff.Invoke();
    }
}
``` this is the debuff class I currently have with the non working invokes
grand snow
#

Ill point out that UnityEvent is a worse replacement for real c# events

#

where do you subscribe to these events though?

silver fern
#

it's subscribed in the skill script, since I was hoping to just call it by name

grand snow
# 
CounterShockEffect effect = new();
effect.onCounterShockOn.Invoke();
#

anyway you seem to only care about half of what I say

silver fern
#

that's not true

grand snow
#

its poor design also to invoke some objects event externally

silver fern
#

ok

grand snow
#

(which is why event prevents this wow who knew!)

#

Look just understand that you can subscribe to an event ON some instance, and then invoke that instances OWN event.

silver fern
grand snow
#

If you want to respond to these events on single instances of the effect, then do not use static

#

but then you need to have a reference to the effect to sub and invoke its events

#

if you want to do something when a specific button is clicked, we sub to THAT buttons on click event right?

#

Same exact concept

silver fern
#

yeah I get that

grand snow
#

then do it correctly or realise what you want is different to what you have created soo far

#

but rn i dont actually understand what you want

#

the effect class has the event so why is it hard to access and use?

rare basin
silver fern
grand snow
#

Then your design if flawed

silver fern
#

yes

grand snow
#

If you can't access an instance then wtf is going on

#

Share how you add an effect to the player/thing

rare basin
#

you can use events on non mono behaviour classes just fine

grand snow
#

You can subscribe to an event in code too

#

Also the only way an event is used

silver fern
# grand snow Share how you add an effect to the player/thing

this is in the EffectController

public EffectObject StartEffect(EffectType effectType = EffectType.None, int effectPower = 1, float effectDuration = 0f, int effectFrequency = 0)
    {
        EffectObject effect = null;

        switch (effectType)
        {
            case EffectType.Burn:
                effect = new BurnEffect(damageController, effectPower, effectDuration, effectFrequency);
                break;
            case EffectType.Slow:
                effect = new SlowEffect(characterController2D, effectPower, effectDuration);
                break;
            case EffectType.Quick:
                effect = new QuickEffect(weaponController, effectPower, effectDuration);
                break;
            case EffectType.AspdDown:
                effect = new QuickEffect(weaponController, effectPower, effectDuration);
                break;
            case EffectType.AtkUp:
                effect = new AtkUpEffect(weaponController, effectPower, effectDuration);
                break;
            case EffectType.DefUp:
                effect = new DefUpEffect(damageController, effectPower, effectDuration);
                break;
            case EffectType.ResUp:
                effect = new ResUpEffect(damageController, effectPower, effectDuration);
                break;
        }

        if (effect != null)
        {
            EffectsList.Add(effect);
            effect.StartEffect(this);
            OnEffectReceived.Invoke(effectType);
        }
        return effect;
    }

    public void StopEffect(EffectObject effect)
    {
        EffectType effectType = effect.EffectType;
        effect.StopEffect();
        EffectsList.Remove(effect);
        // Check if this was the last effect of its type
        if (!EffectsList.Exists(entry => entry.EffectType == effect.EffectType))
        {
            OnEffectEnded.Invoke(effectType);
        }
    }```

which I am doing by checking a bool in the attack script

polar acorn
silver fern
# polar acorn Okay, so, what is "an attack" and how is it changed? Pick one effect, whatever o...

attack is currently this

    public void AttackOne(Vector3 attackDirection)
    {
        //Visuals
        //Anims
        onLiskarmAttackOne.Invoke();

        GameObject bullet;

        if (ultimateAttackEnabled)
        {
            print("enabled");
            bullet = Instantiate(ultimateAttackPrefab, projectileSpawnerTransform.position, gunHandTransform.rotation);
            UltimateAttackScript ultimateAttackScript = bullet.GetComponent<UltimateAttackScript>();
            ultimateAttackScript.speed = attackSpeed;
            ultimateAttackScript.direction = attackDirection;
            ultimateAttackScript.damage = attackDamage;
            ultimateAttackScript.shieldCollider = shieldCollider;
            ultimateAttackScript.shooterCollider = ownCollider;

        }
        else
        {
            bullet = Instantiate(bulletPrefab, projectileSpawnerTransform.position, gunHandTransform.rotation);
            BulletScript bulletScript = bullet.GetComponent<BulletScript>();
            bulletScript.speed = attackSpeed;
            bulletScript.direction = attackDirection;
            bulletScript.damage = attackDamage;
            bulletScript.shieldCollider = shieldCollider;
            bulletScript.shooterCollider = ownCollider;
        }   
    
    }```
polar acorn
silver fern
#

well the attack spawns the bullet basically

#

and gives it properties

polar acorn
#

Just things like "It changes the prefab that gets spawned" or "it changes some numbers in a script" is what would be sufficient

silver fern
#

it changes the prefab yeah

polar acorn
#

Okay, so, the end result is you want a different prefab if a specific effect is active

silver fern
#

yes

polar acorn
#

Okay, and what is the source of the effects? What causes one to be applied?

silver fern
#

the prefab colliding with a player

polar acorn
#

Prefabs can't collide with anything, they're files

silver fern
#

I mean, the instantiated prefab

#

object

polar acorn
#

So, it's like a power-up in the world, and when the player touches it, it changes their attack?

silver fern
#

it happens on a key press

polar acorn
#

What happens on a key press?

silver fern
#

wait

#

the prefab changing effect happens on a key press

#

when the instantiated object collides with a player it can apply effects too

I have a spherical player rigidbody that rotates in midair when it jumps via directly setting its angular velocity; however, because it rotates, when it bounces off the ground it moves in the direction of its rotation, and I don't want this to happen
Does anyone know how to achieve this? I tried storing its angular velocity then setting it to 0 in OnCollisionEnter(), then restoring it in OnCollisionExit(), but that didn't seem to work

hexed terrace
#

constation the position on the rb component?

wintry quarry
#

if you want to avoid it, you can set up zero friction physics materials

devout socket
devout socket
#

UPDATE: Setting dynamic friction to 0 and setting "Friction Combine" to "Minimum" achieves an effect close to what I want, but due to the lack of friction the player doesn't roll, instead sliding along the ground
These facts in mind, how can I prevent the player from rolling when landing due to angular momentum without removing its ability to roll?

Hello. I'm making a multiplayer game using FishNet and having issues with OnCollisionEnter not triggering. I'm using a debug statement right at the beginning of it, so it's not getting returned - it's just not triggering at all. My object it's on has a Rigidbody, with 5 colliders as children. It triggers when it hits another object that is a Rigidbody, but not on anything else with a collider. There are no tags or layers being used on anything - it's all set to default. I tried adding a collider to the Parent and that changed nothing. I confirmed no colliders are triggers. I tested with a mesh collider, a sphere collider, and a box collider, and none of those matter - the only thing that matters is if it has a rigidbody on it. I also confirmed the Rigidbody isn't Kinematic.

#

Oh I also tried changing Collision Detection to all the other types and that didn't work either. I also tried putting the OnCollisionEnter script on one of the child objects with a collider and that didn't work either.

compact sundial
#

I tried all sorts of ways but im stuck

polar acorn
#

So it looks like arrayOfItems is an array of type Item. You cannot store an Item in a string

compact sundial
#

I was just trying all sorts of stuff

rich adder
#

you don't have a string in Item for name or something ?

polar acorn
#

What value do you want in there

compact sundial
#

uh I think I want it to be a image

rich adder
polar acorn

#

idk I was trying random things

So maybe you should think about what you actually want and ask that question

this is what it should be

this is my item class

#

So you probably want a VisualElement that can display an image

#

I'm not sure if UIElements is part of #🧰┃ui-toolkit or if it's a different thing entirely, but there's probably some sort of image component

rich adder
#

tbh If you're new probably easier to make prefab for ugui and spawn those in
UITK you can do

var img = new Image(){
sprite = mysprite
};```
but there is more to it if you want it interactive

I'm assuming either a reference wasn't properly setup or is modified during runtime etc

rich adder

& is the layer index always 0 ?

strange jackal

I check immediately after changing the animation, maybe some lag?

I am controlling animation purely through code

so I need the length to know how long to wait before changing again

Clicking the message once should highlight the animator object. You should verify that it's got a clip

#

if you plan on adding different maps, here is my suggestion
When you figure out chunk placing, place your obstacles where you want, then tag them with what specific object they are. Then make a script that places those obstacles into the specific tagged areas, you'll need to add prefab references

I don't fully understand something. I've tried to make changes to a prefab in the inspector and in the code. The prefab's scripts that change something aren't reflected in the inspector (serialized sections). The code in scripts doesn't seem to update the prefab? Also, if I try to change the rotation of the prefab in the inspector it just appears in the game at its rotation that it had from the start. Totally confused here.

I can already tell there is going to be an issue with the orientation of this sprite and having to transform it (as a projectile) first according to where an enemy is pointing, but also according to the sprite itself's orientation. It's going to get weird.

#

Sprite "laser projectile" is pointing ---> so "up" is it moving up but pointed in that direction (to the right). Solved it with space.world (and rotating it) because the player is always pointing straight up, but once they aren't... gets weird.

does the canvas know that it doesnt actually change every time and redraw every thing each frame? like how the canvas detect change of an element

random lodge
#

Am I wrong in thinking that a sprite (such as a weapon projectile) might need to be pointed a certain way to make your life easier (before you even use it in the project) or I am just confusing myself.

wintry quarry
#

Generally you want the "forward" direction of the sprite to either be facing right or up.

#

The you can always use transform.right or transform.up in your code

#

Not really a code question though

random lodge
#

Yea but a code issue

#

Been having a hell of a time juggling trying to transform / move the sprite in the right direction because of its orientation

#

Not sure if I am confusing myself

wintry quarry
#

Yeah it's best if all of your sprites use the same convention for forward, either up or right but consistent between all of them

wintry quarry
random lodge
#

Well I had to rotate it and use space.world to get a right-facing sprite to fire "up" in game (shouldn't be using world axis obviously yea). I spent way too long trying to figure out what I should do. Now I feel like if I have AI flying around the scene pointing in any directions am I going to have a massive headache getting the rotation of the "laser" going forward from where they are pointing because the sprite has to be rotated before "firing"? I could be making this more complicate than it is.

Guys, my game is on Unity 6.2 and im currently trying to learn to use UI Toolkit. I've been searching on google for a while but i cant find the answer so i will ask here. Which one is better for a story game with levels, 1 UI Document for each scene, or 1 UI Document for each game feature? I've been thinking of doing 1 for each game feature, but i'm not sure cuz im afraid of the performance for having multiple UI Document component in a scene.

random lodge
#

Scratch that I think I found one solution

slender nymph
barren jay
#

yeah, my mistake sorry, i've sent the question there too

wintry quarry
#

The transform.Rotate thing in Start is kind of a red flag

random lodge
#

Had to force it

wintry quarry
#

You can set the rotation when you call Instantiate

daring flax
#

does anyone have a tutorial for making a 2d card game multiplayer? I only seem to see stuff that uses a player object in real time, rather than mirroring a board and having turns

random lodge
#

Most of the time rotation seems to change the axis with it. Up becomes to the left because of rotation.

wintry quarry
#

Which means either your sprite is rotated wrongly in the original image or you did something in the prefab with child objects to achieve that

#

Sharing some screenshots of your prefab would help

random lodge
#

Yea it's like this

image.png
wintry quarry
#

With tool handle rotation set to "local"

wintry quarry
#

So if you moved it "up" it would appear to be going left

random lodge
#

So I should just transform right all the time and consider it forward?

wintry quarry
#

You need to either edit the sprite or start using right instead of up

random lodge
#

So I did transform.Translate(Vector2.right * projectileMoveSpeed * Time.deltaTime); and Instantiate(blueLaserPrefab, transform.position, Quaternion.Euler(0,0,90)); -- seems to work if that's proper I guess I will see later

random lodge
#

for now I assume that as long as I do that it will always "come out the correct end orientated correctly", until I test it in other ways lol

that's what you should be referencing

unless you deleted it

its not supposed to change the button's image its supposed to change the image the newly made object has

#

look at the spawned object at runtime

plush zealot
#

its the same

wintry quarry
#

Have you tried any debugging? Where's your console window?

wintry quarry
#

This code is calling loadPage on the prefab, no?

#

you would need to call it on the actual instance in the scene

#

I also don't even see where you are Instantiating the prefab at all

plush zealot
#

it gets instantiated in 'public void addPageToDeck(); in FightingDeckManager

wintry quarry
plush zealot
#

oh yeah youre right lol i need to call it on the instance of the object

#

ty

wintry quarry
#

Also why is this code so overcomplicated:

        GameObject page2Add = pagePrefab;
        pagesInDeck.Add(e);
        objectsInDeck.Add(page2Add);
        Instantiate(objectsInDeck[pagesInDeck.Count - 1],this.transform.GetChild(0).GetChild(0).GetChild(0)); //child 1 is scroll view obj child 2 is viewport child3 is content
        objectsInDeck[pagesInDeck.Count - 1].transform.position = Vector3.zero;
        page2Add.GetComponent<PagePrefabScript>().loadPage(e);```
#

you have like 4 different ways here of referring to the same object

#

this.transform.GetChild(0).GetChild(0).GetChild(0)
And this is the stuff of nightmares^

null reference stop the code from running

soo... if u get that error anything left in that script isnt gonna work

in the instance yes

but I have that script on different objects

#

the other elements are implemented

#

and still don't return the right element

rocky canyon
#

well ur debug of Null is ur major hint..

#

if its null.. u need to figure out why its null..

#

so.. back-track that variable

#

debug.. it more

#

find out when it becomes null.. or rather... why its null..
instead of what u expect it to be

"Smoothly rotate for a frame" is a contradiction. One frame can have one change in rotation. If you want to do it smoothly you have to do it over multiple frames

# devout socket I have a spherical player rigidbody that rotates in midair when it jumps via dir...

I would like to ask this question I asked yesterday again, as it continues to stump me
Since making that post, I have tried:

  • Using rigidbody constraints to prevent the undesired movement (could not find a good way to store/reapply both angular momentum and direction after the constraints were removed)
  • Changing the player's physics material to remove all friction to prevent the undesired movement (worked, but ruined various other aspects of the player's movement)
    Things I have considered but haven't tried yet, mainly because they sound overly-complicated for the problem I'm trying to solve:
  • Using contact modification to remove friction considerations from the player when it lands (I cannot find any form of documentation or tutorials for the contact modification API)
  • Making a "landing only" physics material that I swap out the regular one for one frame every time the player lands (sounds promising, but also sounds like it will create a lot of problems)
    Could I ask for advice on what to do here?

I think I just fixed it
I remove all friction from the player in OnCollisionExit() and restore it in OnCollisionStay()
Just after that in OnCollisionStay(), I check if the player isn't moving horizontally but does have angular velocity, and if they are, I remove all their angular velocity
Thank you for your help! :)

Hello there, have been learning programming with c# on my own, trying to stay away from chatgpt and discord as much as possible but I have hit one of those no go topics. I am looking into LINQ and all I can find is basic tutorials nothing in depth. I can ask chatgpt but I don't want to as it doesn't help with critical thinking and push us to look for answers.

So here is my question:
I have a list with a class I have created. I will be getting string input from the user and I want to look throught each x string in the array and find the best matches possible from the given string (so not exact match, best matches). Example: Array {"MyPotatos","TheApples","RottenPotatos", "I need help with potatos"} Input from user = "Potatos". From array look through strings and find best matches to user input. Result: "MyPotatos","RottenPotatos", "I need help with potatos"
please someone help people

alright

i got you

kinda looks like the mount location field is grayed out?

(why make it an Object though)

GameObjects and Transforms are 1:1

slender quiver
#

see before i got type mismatch

#

dropping the GO onto the Transform field

naive pawn
#

huh come to think of it, that could be why - it'd be ambiguous what you're trying to assign

slender quiver
#

thats why i tried to drill down into the setter and make it possible to use a GO or a Transform explicitly

naive pawn
slender quiver
#

and it forced me into using Object instead of GO

#

so idk

naive pawn
#

what object are you trying to assign onto?

#

ah wait, a ShipData SO, right?

#

im not sure you can reference children of a prefab like that..

#

it's kinda like the scene object into asset context thing

slender quiver
#

hmm, how to best store the information then

naive pawn
#

would it be possible to just store it all as a component on the prefab?

slender quiver
#

yeah so i should just make the ShipData an MB instead of an SO, basically?

naive pawn
#

yeah

#

if that makes sense for the data you need to store - i don't have full context of what you have the SO doing

slender quiver
#

well its supposed to be data on the ship in question. name, nation, type, level requirement, what weapon mounts it has for primary/secondary guns, where the transform to instantiate whatever guns get equipped goes, the rotational limits for each turret location, etc

yeah that probably could be on the prefab

https://paste.mod.gg/tkekcmnhsknf/0 how can i make sure that the player doesn't get bounced up whenever the paltform moves down or up? (one reminder, the reason why i am not using parenting because that would make that the player unable to follow the platform despite being a child object to it because the platform is kinematic and the player id dynamic, even whe full kinematic contacts, it wont work)

BlazeBin - tkekcmnhsknf

A tool for sharing your source code with the world!

frosty hound
#

How are you actually applying the force onto the character controller when it is on the platform?

hushed hinge
frosty hound
#

Well, ignoring the fact that alone is a red flag, then of course it will make your player "float" at the top because the frame before the platform goes down it has moved your character up one frame by the movement delta. And because your character's falling has acceleration, it's "disconnecting" from the platform.

#

Anyway, the solution is likely in needing to flip the authority on what has control over your character. The platform shouldn't be "moving" the rider at all, it should only care about it's current velocity. The rider is the one that should be detecting that it is on a moving platfom and then applying the velocity of that platform to it's combined velocity/input from the player.

hushed hinge
# frosty hound Anyway, the solution is likely in needing to flip the authority on what has cont...

I get what you mean about flipping the authority, I’ve tried the ‘platform just provides velocity, and the rider applies it’ approach a bunch of times. The problem I kept hitting is that because my platform is kinematic and my player is dynamic, simply parenting the player to the platform doesn’t work, the player won’t inherit the movement, even with useFullKinematicContacts enabled. That’s why I ended up trying to directly add the delta to the rider’s position

frosty hound
#

Switching the authority has nothing to do with parenting the player. That should never be a thing.

hushed hinge
#

Then I don't know what to change

#

or what authority you mean

frosty hound
#

Right now your platform is actively overriding the position of the thing that is on it, that authority.

#

Your platform should be a dumb object that has no idea anything is on it. It simply goes about moving along it's assigned route.

#

The actual smart object, your character, is the one that determines it is on a moving platform and takes the velocity of that platform into account when determine it's current frame velocity by factoring it into whatever other velocities are being applied - such as your input.

#

The platform can have it a property Velocity that it continually updates as it moves about, which your character can use.

hushed hinge
#

so, make a different script something like PlatformRider for the PLayer?

slender quiver
#

Maybe generalize it more. A script to detect what the player is in contact with, reference its velocity for its own velocity updates

#

all surfaces, even mobs maybe, expose their velocity. if player stands on something, it will interpret its velocity as a product of input + surface its on. most surfaces wont move and have velocity of zero

hushed hinge
#

or player have another script that checks if it's on the platform?

frosty hound
#

However you want to do it 🤷‍♂️

#

The theory is there, you can execute it

hushed hinge
#

yet i am afraid that the player woudl still bounce up anyways

frosty hound
#

Then that would be an issue with your implementation

hushed hinge
#

well i am thinking on changing up the platform script first

#

so is there a script i can find and maybe a tutorial that have like a separate script that detects when the player is on the platform?

frosty hound
#

If there is, I'm not going to be the one to look and find it for you 🤷‍♂️

hushed hinge
#

well already looking for it

frosty hound
#

This video implements it the same way you have, and suffers from the same issue. Their bandaid fix is to increase the gravity scale so that you don't notice the disconnecting because the player essentially speed falls back into the platform.

hushed hinge
#

oh

#

but still work in a way?

frosty hound
#

Sure, until you find another edge case where it conflicts and are back here asking how to work around that one.

hushed hinge
#

ok

This Awake() method is called whenever a new weapon is picked up. It is specific to each weapon. Is this okay?

#

I dont see why not

keen dew
#

It's "ok" in the sense that it probably works but it's not really following any best practices. It looks like those scripts should be singletons or there should be one (or more) top level managers for handling those things

west sonnet
slender quiver
#

exactly, attached to a gameobject placed somewhere in the scene

keen dew
#

Either a singleton that you can use to access those components anywhere (Manager.CamRecoil for example) without having each individual component find the components separately, or a manager that creates the weapons and assigns the references to the weapons at that point

slender quiver
#

for instance you can see my GameManager object that has a few management components attached to it in the inspector

#

What's the benefit of using a GameManager like that? The components I'm referencing are being used in that same script, so would using a GameManager make it more complicated?

You make serialized fields and drag the references in the inspector

Serialized fields in the weapons script?

#

No in the manager

west sonnet
#

Oooh, so I don't need to do the FindObjectWithTag ?

keen dew
#

Then in the weapon script GlobalReferences.Instance.Camrecoil

#

Yes the entire point is to avoid using the Find* methods

west sonnet
#

Right, that makes sense. Thank you

I go the route of manual initialisation so I can provide dependencies then as args and avoid both find and static fields

Hi, I'm a bit new to using the profiler; what does these mean (and why is EditorLoop taking the most Time ms)? I'm on deep profiling mode and these seems to be Unity builtins or some sort?

image.png
#

additionally the game is stuck at ~60fps despite the target fps being set to 90 (tried disabling vsync whenever possible)

grand snow
#

In editor the editor executes things each frame which is why its included in the profiler
PlayerLoop is for the game

#

14ms to render canvases is pretty high

worn bay
#

All I'm seeing is extension/builtin calls

grand snow
#

How much stuff is in your canvas? Are you making use of sub canvases?

#

We can see canvas render has the 14ms time

worn bay
#

the canvas in said scene looks like this

image.png
#

(On 2022.3 btw)

grand snow
#

When a single object in a canvas is made dirty the whole canvas has to be rebuilt

#

You can use canvas components within a canvas (add them to child objects) to optimise what gets rebuilt

worn bay
#

(the canvas child is just Transform and RectTransform iirc)

grand snow
#

its easy
If you have a fuck ton of things in 1 canvas its going to increase its redraw cost greatly

#

e.g. add canvas component to "Game View"

#

may also require a graphic raycaster component if input stops working

#

Hopefully you know what things in your canvas get changed a lot so you can judge best where to have a "sub canvas"

#

The point is to prevent things that dont change very often or at all from being re built

worn bay
#

well I'd say having to redraw the entire HUD and other stuff just because it triggered a hit particle would make sense that it'd be costly

grand snow
#

Does this make sense though?

worn bay
#

do I just do it like this?

image.png
grand snow
#

yep and now its children will be rebuilt by this canvas and its seperated from any parent canvas

#

Don't slap them everywhere but where it makes sense

worn bay
#

do I need to update any scripts for that to actually happen or the editor will just take care of it?

grand snow
#

nope nothing like that is needed

alr thanks

# grand snow keep it up 🧠

Well I'm having issue with lookups now

// Navigate forward
while (true) 
{
    // Get the next timestamp in the list
    Timestamp timestamp = null;
    
    foreach (Timestamp storyboardTimestamp in Storyboard.Timestamps)
    {
        if (timestampType.ID == storyboardTimestamp.ID)
        {
            timestamp = storyboardTimestamp;
            break;
        }
    }

this is a bad search method for something done on high volume of calls, but it's too simple to be able to think of anything better UnityChanLoom

keen dew
#

At a surface level, use a dictionary instead of a list. "Get the next timestamp" suggests maybe they could be ordered so that it could just pick the next index

worn bay
#

ID is an enum, if that helps

grand snow
#

Cool that works in a dictionary still

keen dew
#

or if the data is paired then make them structs so you don't need to search for the pair every time

worn bay
#

Tried it, it breaks (oor it's just I'm too incompetent to mess with this >.>)

keen dew
#

it's the latter I'm afraid

worn bay
#

I don't have a good grasp on how dictionary lookups would work

#
  • last time I have dictionaries in other places, it has a pretty high self ms in profiler for some reason
grand snow
#

It should be better when you have many things in a collection

worn bay
#

do I keep the timestamp = null part

keen dew
#

If there's more than 1 or 2 items in the collection it's pretty much guaranteed to be faster than iterating through a list

#

unless there's a custom hashing function and it's royally messed up

worn bay
#

Well iirc Storyboard.Timestamps is sorted chronologically (since it's a rhythm game)

#

so grouping it by IDs sometimes makes me think it's not the best idea

keen dew
worn bay
#

when I implement it, it either; 1. Executes by type instead of time (i.e Rotates THEN transforms, instead of doing both in parallel) or 2. It stops moving altogether

does anyone here know a lot about using scriptable objects?

keen dew
#

If you have a question just ask it and if someone knows they'll answer

silver fern
#

I currently have a badly designed buff debuff system that I'm supposed to replace by a system using scriptable objects but I can't figure out how to do that in a way that actually improves my situation

limpid cloak
#

i wanted to create an if statement that checks the amount of instances of a specific gameobject currently present in the scene and if they are higher than a set amount, it would disable the player's ability to spawn more, but apparently you can't just use >/</= signs for gameobjects

keen dew
#

Well you can use them for the count of gameobjects but that's a bad way to do it

#

Make a variable that tracks how many have been spawned

west sonnet
limpid cloak
#

probably because it's more laborious to make it account for the gameobject deletion

#

like it can count but you also need to make a separate instruction to decrease the counter when the gameobject is deleted?

limpid cloak
#

i could make a list i guess

keen dew
# west sonnet Why is that a bad way to do it?

Basically the same reason why using Find is bad, because information about the state of the game should not be derived from the scene but there should be an authoritative source about the state

#

Counting the gameobjects is fine but arguably better would be to have something else track them. Store them in a list and remove them from there the same time they're destroyed

slender quiver
#

ideally being the thing that issues the command to create whatever it may be that youre tracking, and such

silver fern
#

alternatively, does someone know a good way to invoke a unity event in a different script?

slender quiver
#

single source of authority and all that

keen dew
#

Also if you're just counting the instances that are in the scene it implies that there's nothing controlling what can spawn the instances and they can just be created willy-nilly. Having just one thing be responsible for spawning and destroying the objects pays in the long run

limpid cloak
keen dew
#

I was thinking you'd store the instances in the list because it can be useful for managing them also in other ways

#

but if you just want to keep count then make an int and ++ it

limpid cloak
#

i mean i could do that i guess.. i'm not familiar with managing objects and instances scripting wise. unity tutorial makes them feel almost like classes

keen dew
#

And again it's fine to just count the objects if you don't want to completely redesign the code structure. Just remember to check the count with >= etc instead of the collection itself

cosmic dagger
limpid cloak
cosmic dagger
limpid cloak
#

oh ok you mean like that

#

i'll see what i can come up with

cosmic dagger
limpid cloak
#

ok, i made a private List<GameObject> dogCounter = new(); and added a dogCounter.Add(gameObject); in the if statement. now, this is all on a PlayerController monobehaviour, but what removes the game object in question is inside another monobehaviour called DestroyOutOfBounds. can monobehaviours share commands or communicate with eachother? if not i will just add a timer that makes the list delete one item after the amount of time it takes for the object to go OOB and get deleted

balmy vortex
#

Does anyone know how to actually sync up my health bars value to the value in my code?
rn it grabs the value from the slider but altering it in the code doesn't actually do anything and changing the healthSlider to be static kinda just breaks everything

cosmic quail
#

so if player health is 50 then slider should be 0.5

cuz crossposting is against the rules

silver fern
#

I'm not using static anywhere, my method is public override void StartEffect(MonoBehaviour mono) { Debug.Log("invoke event"); Debug.Log(mono); mono.FindAnyObjectByType<LiskarmSkillScript>().onCounterShockOn.Invoke(); }

#

and I get that error

keen dew
#

In your code the type name is MonoBehaviour and instance reference is mono

silver fern
#

ohh

#

thanks

keen dew
#

so "cannot be accessed with mono; qualify it with MonoBehaviour instead"

silver fern
#

is there any way to limit the find to only look in components attached to the character the find was called from?

#

I'm in EffectController and want to find a component in PlayerControllers, but when I have two of the same character, it finds the component in the other character instead of this one

# silver fern it's not a child

You should properly provide all the information instead of drip-feeding. It's hard to tell what you need with so little information . . .

silver fern
#

I doubt you want to know all of it

#

but I can show you all of it if you want

#

I did post the screenshot of the hierarchy showing its a sibling

#

actually I can probably do something like parent.GetComponentInChildren

#

hmm it doesnt know parent

keen dew

transform.parent

silver fern
#

thanks that did it

cosmic dagger

#

wut

limpid cloak
#

still, learning is important

#

unrelated to unity, but how do you disable in VS that thing that makes you replace a character instead of inserting a new character? like when it does that grey overlay over a character

if tireTemp > ambTemp.. then the nested if statement would never be true

maybe u didnt meant to nest it there

languid pagoda

#

ya, but it runs in a single frame..

#

the NEXT frame when it loops back over..

#

think about it in terms of values.. and step thru it..

#

if u step thru it.. its never gonna run

#

maybe 1 single time

#

ahh

#

ur using it like a clamp

yes

okay carry on then, mb

no problem lol i was so confused

me too 🫠

#

im about to ditch it and try again anyways

rocky canyon
#

i would.. if its taking consider amount of time to debug

#

it might be more cost efficient to redo it

strange jackal

I stripped it down, added a sphere, added a rigid body, added the script
void FixedUpdate() { Debug.Log("is fixed working ?" + Time.realtimeSinceStartup); transform.GetComponent<Rigidbody>().AddForce(transform.forward * 20, ForceMode.Impulse); }
and it works, so must be a problem with my arrow object

ohh... and i also agree w/ u bout the car stufff

should I use FixedUpdate? or just Update

yo russell.. ur values are probably way too high

#

ok thank you so much

rocky canyon
#

u need really small decimal values

#

like coolingrate would be like .2f

heatingCoefficient should be even smaller like .0002f

languid pagoda
languid pagoda
#

i was using like 0.5

rocky canyon
#

Treat coolingRate and heatingCoefficient as tuning knobs. Start super low, then bump up until it “feels” right

#

and i mean super low lol

#

since ur running possible +60fps

languid pagoda
#

thats getting called in my physics substep, its being called 200 times every fixed update 😭

rocky canyon
#

i havent done car mechanics in quite a while so im a bit rusty

#

but last time i did something lkke this was for losing airpressure

#

and it was a really small decimal

rocky canyon
#

f Unity is doing ~50 fixed updates per second → that’s 200 * 50 = 10,000 calls/sec. No wonder your tires are going nuclear 👀

#

u can use ur substep as a factor for ur values

#

tireTemperature += (heatGain / stepCount) * Time.fixedDeltaTime;

#

(heatGain / stepCount) shuld normalize it abit

#

that would give a value closer to what i was mentioning earlier.. like .000x

languid pagoda
#

if (heatGain > 0f)
tireTemperature += heatGain * deltaTime;

deltaTime is defined as Time.fixedDeltaTime / 200(number of substeps).J shouldnt that be enough?

#

Ill give it a try now tho

#

Thanks for your advice!

rocky canyon
#

ohh so u are already doing that

#

ur just manipulating the deltaTime before pushin it thru

#

odd way of doing that imo lol

#

it would work but its a bit confusing

#

b/c deltaTime now doesnt actually mean Unity's DeltaTIme

#

could be throwing off code further on down the line

#

i'd use my ownvalue like that factored value first

languid pagoda
#

but setting the heating coeffecient really low actually made it work!

rocky canyon
#

and then use regular delta

languid pagoda
#

so thank you

rocky canyon
#

happy to help

#

may want to make u a debug panel to log the values real-time

#

on ur game..

would really help visualize whats happening as u play-test

where can I learn HLSL that will work with the newest unity?

everything is outdated 😮

fierce shuttle
#

Unless they significantly changed how the pipeline and shaders works in the newest versions, I dont think shader language can become outdated, I had some shaders work in HDRP 2020+ versions that was written for Unity 5, with the biggest difference being a choice betweeen writing HLSL or using ShaderGraph (which is just a visual editor for HLSL with pipeline-specifics thrown in AFAIK)
