If Im checking for colliders in the long grass do I want to use Update or FixedUpdate?

[timber tide]

with what method

[shy ruin]

No way

I solved it

[timber tide]

honestly, if you're not shooting projectiles at 50+ units a second you can use either

[shy ruin]

I was changing the transform of the player, which held the camera, and then I set the camera to the correct rotation. They conflicted with each other it seems.

Someone gotta write that down.

[queen adder]

anyways, is there a way i can have a float[] with multiple slider like this?

in editor

[timber tide]

Usually late update solves those issues, but perhaps you were also rotating more in late update

[shy ruin]

I also got a lighting problem that only occurs in the Build.

[timber tide]

so then you probably* had some race conditions on the execution ordering

[shy ruin]

No idea why this happens on the build 😭

Not in the editor

[timber tide]

#archived-urp

[shy ruin]

oop

[eternal needle]

Yea if you create or find an asset which does this

[lavish magnet]

How should i modify this alpha value?

[glossy turtle]

renderer.material.color = new Color(renderer.material.color.r, renderer.material.color.g, renderer.material.color.b, newAlpha);

[lavish galleon]

Is anyone available for like 3 min? that knows about A* Pathfinding, Ill share screen to make this faster, but I am having an issue where if i have multiple units, and they collide (40 units) they start floating, Im also usin a rigidbody for the colliders

[dense root]

How do I avoid using a RigidBody2D for my TileMap?

private void CheckForEncounters()
{
    if (Physics2D.OverlapCircle(transform.position, 0.2f, grassLayer))
    {
        if (Random.Range(1, 101) <= 10)
        {
            Debug.Log("Encountered a wild pokemon");
        }
    }
}

So I can run through the grass as intended, instead of being blocked by the RigidBody

[lavish magnet]

This works, it changes the alpha but the zombie material itself doesnt actually become transparent?

[glossy turtle]

the alpha value 0 means transparent.

[lavish magnet]

Yes the code works gbut the zombie doesnt become trasnaprent

Alpha is 0 but its still visible

[glossy turtle]

post the code so that others can try too.

[eternal needle]

Could you not just disable the mesh renderer?

[lavish magnet]

I want a smooth fade out

[lavish magnet]

But even in the inspector, changing the alpha does nothing

[eternal needle]

It would have to be transparent but there are other issues if you make it transparent. Like you'll see the arm render through the body

[lavish magnet]

I made the surrfcae type transparent but now I just cant see the shadows?

[eternal needle]

Well yea there are issues with making it transparent, as I said. Look into other methods like possibly dithering

This would be more of a shader solution

[lavish magnet]

Its really this hard just to make something fade out 😭

[eternal needle]

I wouldnt call this hard, considering it's just the first thing you tried that didnt work.

[glossy turtle]

what is the rendering mode.

[lavish magnet]

Tried a shader graph too

[lavish magnet]

Transparent

[glossy turtle]

change it to fade.

[lavish magnet]

Rendering Mode? Thought you meant surface type

[eternal needle]

🤷‍♂️ well dithering is a common technique. Try again then. Cant really say much based off so little information

[lavish magnet]

i dont know where rendering mode is

[glossy turtle]

apply a standard shader and change it to fade

[lavish magnet]

im in URP

[glossy turtle]

you need to learn shader graph if in urp.

writing custom shaders. etc.

[rocky gale]

This is a coding channel

[void seal]

Would a coyote timer best be put into void Update()?

[willow scroll]

Coyote timer is when the player still is able to jump for a few milliseconds after falling from a cliff?

Then yes, you can put it into Update

[void seal]

Gotcha. Still getting acclimated to the Unity API again. Been a hot minute.

[summer stump]

it could also be a coroutine

Update makes the most sense though for something like that imo

[eternal needle]

Shouldnt really matter what you do as long as the solution works. You could even have a float which you store a time which is last valid for a jump.

[willow scroll]

Actually, I would

• Start a Coroutine when falling from a cliff, which waits for the specific period of time. Once the time has passed, the bool canJump is updated to false
• When the player enters the ground, the Coroutine is stopped and canJump is updated to true

[void seal]

Gotcha. Yeah doing something simple. 0.0 on ground with += Time.deltaTime and then a check for amount of time passed.

[eternal needle]

I really wouldnt go with a coroutine here. You're likely checking if the player is grounded anyways, during this same check you can just store a float saying what time is still valid to jump. Like Time.time + someAmount.

[void seal]

Ye. I like that approach because it's pretty universal and not spaghetti.

[willow scroll]

Coroutines are never spaghetti

[viral shadow]

hey can someone please help?

[wintry quarry]

It's a static method

[void seal]

Wasn't referring to courtines specifically. I respect what they bring to the table.

[viral shadow]

meaning?

[wintry quarry]

so you just do Color.HSVToRGB(...)

new Color() is to create a Color object

you don't want to do that

you just want to call a static method

[viral shadow]

ohh so no new needed

[wintry quarry]

new is only for creating objects

[viral shadow]

hmm im getting this error now

[wintry quarry]

() ?

[willow scroll]

Static methods don't have an instance of the class created. Instead, reference the class to access them directly

[viral shadow]

oh

so no brackets

thanks so much

[wintry quarry]

I showed example here

[viral shadow]

sorry im very very new

[willow scroll]

Now you're kinda stuck between accessing a static and non-static variable

[viral shadow]

and how do I get a random value?

figured it out

[void seal]

I'm mostly rubber-ducking here but I think this would be the spot where I run the check for the coyote timer, yeah? Not currently worrying about double jumps at the moment for it, just my jump count leaving a ledge. If jump count = 0 and coyote timer is not equal or greater than "insert value here"?

[ruby flower]

Im new what is the difference between if and boolean

When do you use them

[solar agate]

if is a control flow statement for making decisions based on conditions, while boolean is a data type representing true or false values.

[summer stump]

An if statement evaluates a condition. That evaluation returns a bool (true or false value). if it is true, it executes the code in its body. If not, it does not

[stray pivot]

in other words boolean is a variable if is a statement

[eternal needle]

you should do some c# basics tutorial, outside of a unity context. Theres good resources out there like the microsoft learn site or really anything free. This is stuff you'd really wanna do hands on work with to experiment what they do

[ruby flower]

Yeah i was looking at some Code Tutorials haven’t really got experience with unity

But i want to become Game dev

I learned Blender past 2 months

Now coding 💀

[eternal needle]

theres a decent amount of learning that needs to come before just doing unity, yet a lot of people skip the basics and suffer the same. Id say once you're familiar with classes and can solve basic data problems, you probably have enough of the basics.

just so i can put it into perspective, a blender comparison would be giving someone whos never used a computer blender and told them to make a full character model.

[ruby flower]

Which. Videos do you recommend

For starting

I know the ui and Where i Can find all the stuff

Know some of the small basics

[ruby flower]

That’s Hard XD first thing i tried and then i realised you Need to start small

And That’s how i started

[eternal needle]

Havent seen a beginner tutorial in probably 8 years by now. for c#, microsoft has a lot of videos but i havent seen them, they are recommended a lot. https://dotnet.microsoft.com/en-us/learn/csharp
w3 schools is decent and has an interactive website. Very small "lessons" per page too https://www.w3schools.com/cs/index.php

The Junior programmer coarse:O

[quasi sparrow]

Hey guys , what's the best free course for unity LTS

[fossil drum]

Just start with the courses pinned in the top right.

[burnt vapor]

Color does not have an empty constructor. https://github.com/Unity-Technologies/UnityCsReference/blob/master/Runtime/Export/Math/Color.cs#L36
You want to use the static method like they specified: https://github.com/Unity-Technologies/UnityCsReference/blob/master/Runtime/Export/Math/Color.cs#L303
Alternatively use a constructor that takes the correct arguments. This does not work properly for your use case due to convertion, though.

Next time you encounter an error when you expect it to work, you can often Google Unity's source code like with this

Doesn't apply to everything, though

[tulip edge]

i'm following Brackey's tutorial on the first person camera movement, this Mathf.Clamp here is setting my camera rotation to 90 whenever i start the game, this means that the camera will look down.
If i start moving my mouse then the script will work as intended but i need a way for the camera rotation to start on 0 and not 90

[deft grail]

you want it to not move at all?

[tulip edge]

i need the x rotation to START on 0, sorry

[deft grail]

ok then just change that in the inspector? also remove the * Time.deltaTime

[tulip edge]

nope, won't do, because in the very first frame the rotation gets set from 0 to 90

[deft grail]

try removing the deltaTime and see if that changes anything

[tulip edge]

didn't change anything

[deft grail]

ah actually, maybe its that line where you set the rotation do = Quaternion.Euler(0, 0, 0); instead
in Start

[tulip edge]

i added it hoping it would fix it, but no, it's useless actually, because even if the rotation gets set to 0 in start, t will be set to 90 in the first update loop

[void thicket]

Does your object have parent?

[deft grail]

code looks fine i guess, how is the hierarchy setup? maybe something wrong with that

[void thicket]

I don’t think that will clamp to 90

[eternal needle]

Maybe just look into using cinemachine which is a premade camera controller and will be miles better than anything any of us write. Brackeys code is very.. not good.

[tulip edge]

ok, found the solution... this might be an editor only issue, if you start the game in the editor and keep the mouse pointer above the game windows, then the rotation will be ABOVE 0

this means that the starting rotation of the camera is dependant on the mouse cursor position

[eternal needle]

Theres definitely more issues than just that, if what you described is one.

[tulip edge]

alright, sounds like a solid idea

[eternal needle]

Just a side note, mouse input shouldnt be multiplied by delta time. And same as what gr4ss said above, you shouldnt be directly setting values xyzw of a quaternion (which was done in start) These arent euler angles, so the quaternion you had there was actually invalid

[tulip edge]

alright, i see

[idle elk]

Hi my name is ikmal .. can you help me solve this problem ? im using playerprefs to save and load stoned to others scene .. this game have 5 level and need to collect 1 stone from each level before can colllect the stone player must collect all the calorie then the stone can be collect and go to next level .. after collecting the stone player can see all the stone at others scene name "pyramid stoned" the problem is only 1 stone level 1 save and appear at scene pyramid stoned the rest dont appear .. in debug say the state is same for all stone ..how to solve this?

You can see the script below

https://pastebin.com/jysWPVkh

https://pastebin.com/8PhaYNTz

[ivory bobcat]

Can you show the logs?

[idle elk]

Sure wait

[ivory bobcat]

Put a comma and the variable stone after the logs in set stone visibility.cs Debug.Log("...", stone);//Example

Then click on the messages in the console and see which objects in the scene are highlighted.

Single click

[void thicket]

FYI PlayerPrefs persists across your levels

It’s not like they have separate save per scene

[idle elk]

Do i need to separate save each level so they can display all collected stone?

[void thicket]

If you want to save per-level per-stone then you need unique key as combo of those

Or make proper save file system

PlayerPrefs are not for savefiles in the first place

[blissful spindle]

hi, I want to ask for help I am trying to add some kind of recoil to my script so the bullets dont travel in the same direction, any ideas on how to add random offset to the bullet so it goes a little bit to the right or left(that would depend on randomization) https://hatebin.com/aadainnaea

[keen dew]

You have to fix all compiler errors before it appears

Find what?

Open the console

The script is missing the using UnityEngine.SceneManagement; statement

Configure the !IDE so that it shows the errors while you're writing the script

[upper forge]

hi guys, i have this script which is attached to my coin prefab which gets spawned with my "Spawner" empty GameObject, which is executed every two seconds, the script is meant to destroy the Coin everytime it collides with an object with the tag "Player" but does not work.

using System.Collections.Generic;
using Unity.VisualScripting;
using UnityEngine;

public class collisionCheck : MonoBehaviour
{
    public GameObject coin;
    private void OnTriggerEnter2D(Collider2D collision)
    {
        if (collision.CompareTag("Player"))
        {
            Destroy(coin);
        }
    }
}

nevermind, turns out isTrigger wasn't on

works now

[keen dew]

If this script is on the coin you can just do Destroy(gameObject)

[upper forge]

it gives me an error everytime i do that, so i just did what i did instead

[trail gull]

I have a 2d enemy sprite navmesh, how would i make them jump over a gap instead of just gliding over the gap? No special animations, just up and down

I want to see them go up and down rather than just 'walking' over the gap

[teal viper]

What's a sprite navmesh?🤔

[trail gull]

Not a sprite navmesh

Just a navmesh but its a 2d character

[teal viper]

What? A character is a navmesh??🤯

Do you mean a "navmesh agent" perhaps? Because navmesh is the thing that it walks on.

[trail gull]

Yeah

[teal viper]

Ok, well, you could use trigger colliders to detect when you character gets close to the gap and execute a jumping animation.

[lost summit]

its possible to change size of cube to match camera viewport size? what I want to cube always be inside viewport facing only one side

match size of face 1 with camera viewport on 2

[halcyon shard]

Hey guys! Trying out the unity beginner course and decided to mess around with the prototypes given, but I keep coming into some clipping issues with the boxes. I was just wondering why this happens and how to avoid it in future endeavors.

Apologies for the lack of a gif or video, I have no idea how to record, fit and upload that onto discord

[fossil drum]

My guess is that you move the truck without the Physics methods, but without code its hard to tell.

Can you post the !code?

I did indeed, I just put a simple transform script without a physics method since I didn't know how to use one and wasn't shown on the course. I shall go ahead and look up how to do that! Thanks a bunch

[fossil drum]

Transform scripts don't work well with physics. You need to use the physics methods otherwise you get things like this. Or bullets that go through walls, stuff like that.

[halcyon shard]

Gotcha, I have no idea on where to start understanding physics methods but I shall try my best! Any advice on where I can start learning them?

[deft grail]

just look at the documentation for Rigidbody.velocity/Rigidbody.AddForce

[halcyon shard]

Thanks a bunch!

[molten dock]

is it super hard to add a save game function

[willow scroll]

Yes, it's possible to change the size of the GameObject to match the camera's viewport size.

Orthographic

For an orthographic camera simply calculate the height by multiplying the orthographicSize by 2, as this is the camera's half-height. Then calculate the width by multiplying the height by the camera's aspect ratio.
As you may notice from using the orthographicSize, this won't work properly with a perspective camera.

float height = camera.orthographicSize * 2, 
    width = height * Screen.width / Screen.height;

transform.localScale = new(width, height);

Orthographic & Perspective

To calculate the perspective camera's size, which also works properly for an orthographic one, you have to simply calculate the difference between the world space points and use some mathematical multiplication formula you should have learned at school, which tells you a - b | x - y => a = b * x / y. In our case a is the world space scale you want to get, and the division by y is not required, as this is simply Vector2.one - Vector2.zero = Vector2.one in space coordinates.

float cameraDis = transform.position.z - camera.transform.position.z;

Vector2 dis = GetPoint(Vector2.one) - GetPoint(Vector2.zero);

value.localScale = new(dis.x * Screen.width * sizeMutliplier.x, 
    dis.y * Screen.height * sizeMutliplier.y);

Vector2 GetPoint(Vector2 value) => 
    camera.ScreenToWorldPoint(new(value.x, value.y, cameraDis));

You can also create a static method in some Extension class in your script, and access it when required.

SetCameraSize(transform, Camera.main, Vector2.one * .5f);

In this case, transform's localScale is modified according to the Camera.main's viewport, and it fits 50% of it. In your case, it should be 100%. You can also extend the method by adding overloads.

        agent.SetDestination(target.position);
    }

[keen dew]

I don't know if it's just bad naming, but now it reads "if the enemy doesn't need to jump, jump across gap"

[trail gull]

It is bad naming, needstojump returns whether there is ground below and !NeedsToJump is if there is no ground below

Poor naming

[cosmic dagger]

how about calling it IsGrounded?

if (!IsGrounded()) {
  // Jump!
}```

[trail gull]

Just did that now

But still need to figure out why its constantly jumping

[cosmic dagger]

you can mix them. performance depends on how the code or visual script is written/setup and its complexity. you won't know until it happens. then you profile and optimize when needed . . .

[keen dew]

What exactly is the situation where it's jumping when it should not? The code tells it to keep jumping as long as it's within lookRadius and there's no ground below

[cosmic dagger]

so it's constantly jumping across gaps?

[trail gull]

Im just writing code to make it jump across a gap, so when there isnt ground below it should be jumping across the gap

[trail gull]

Just constantly jumping, not just across gaps its just bouncing

[keen dew]

Have you checked what NeedsToJump returns when it's not on a gap?

[sleek pond]

Why it is throwing this error??

[languid spire]

please do not post photos, use screenshots

[sleek pond]

Ok

[cosmic dagger]

this is terribly hard to see or read. please use a screenshot . . .

[sleek pond]

Okk

[willow scroll]

Because there is even no condition

is not a condition

Use at least true or false

[swift crag]

ifn't

[sleek pond]

It's error about )

[swift crag]

yes, because that's bogus syntax

you are not permitted to write an if statement with no expression inside of it

[cosmic dagger]

look at a tutorial for "c# if statement" and you'll learn why . . .

[swift crag]

the compiler sees if followed by a (, so it's now expecting an expression, like true or 3 < 5. but you just gave it a ), which is not a valid expression.

[sleek pond]

I have written

[frosty hound]

As people been telling you if() isn't valid code. You need to learn how to do if statements in C#.

[sleek pond]

Ookk

Okk

Thankyou

[cosmic dagger]

did you read any of the messages that everyone responded with? they explained what the problem is . . .

[sleek pond]

Sorry

[frosty hound]

You can always look at the documentation to see examples too:
https://docs.unity3d.com/ScriptReference/Input.html

[cosmic dagger]

but the screenshot is great. very acceptable over a phone grab . . .

[sleek pond]

Ok I got this now

[trail gull]

Im gonna switch to using colliders instead of raycasts, feel it'll be easier

[swift crag]

if you want to check for ground colliders in a volume, use a Check* query

like Physics.CheckBox

this will be significantly simpler than responding to collision or trigger messages

[trail gull]

Could you explain a bit? I dont understand

[swift crag]

https://docs.unity3d.com/ScriptReference/Physics.CheckBox.html

It tells you if there are any colliders in a box.

[trail gull]

Nevermind there is a far easier way to do this jump thing

[willow scroll]

Which you haven't even explained

[trail gull]

Well.. I got it working

[queen adder]

i want to make it so when im dragging a object it can build momentum and would get flung when let go any ideas?

oh ok

okay

[swift crag]

A spring applies more force as you stretch it further

If you double the stretch, you double the force

[swift crag]

Does this object have a rigidbody on it?

ah, it does, given the code

[queen adder]

yes

[swift crag]

                rb2d.AddForce((mousePos - heldObject.position) * 6f);
                rb2d.velocity = ((mousePos - heldObject.position) * rb2d.mass);

Just get rid of the velocity assignment and this should be fine

This applies more and more force as the object gets further away

you're currently setting the velocity every frame (using the mass for some reason?)

so the force you apply doesn't do very much

Also, consider moving this into FixedUpdate.

[queen adder]

wait should i move all the code into fixed update?

[swift crag]

At least the part that is applying forces.

I would keep the part where you check if the mouse is clicked in Update, so that it runs every frame.

[queen adder]

ok will this work even with me moving the held object to the cursor

[swift crag]

Physics2D.Raycast(mousePos, mousePos);

this doesn't make any sense

this is shooting a ray from mousePos...in the direction of mousePos

so it'll shoot a ray away from the center of the screen

Use Physics2D.OverlapPoint to check if your mouse is over something.

Also, this code checks for the object every frame, so you'll lose your grip on the object if your mouse goes off of it

You can use Input.GetMouseButtonDown(0) to check if the mouse was clicked this frame

[queen adder]

i dont really know to make it head towards the center

[swift crag]

you shouldn't be using a raycast at all

[young fossil]

Hello, I am looking for advice on programming a capture-the-flag, strategy type AI. Been researching into behavior trees, FSMs, utility AI and a couple of others, any advice on which the "best" or generally most accepted one is? thx

[swift crag]

You will want to give the rigidbody some drag, yes

Otherwise it'll oscillate back and forth forever

[young fossil]

I guess there isn't a best, but could you please review these

Have you used them before?

How did you implement them?

[swift crag]

Unity doesn't have a behavior tree system

[young fossil]

Animator?

[swift crag]

I imagine there are third party packages, though

[languid spire]

I, not so long along made a capture the flag RTS using Unity ML agents. The results were amazing

[young fossil]

ML agents? Sorry I don't know what that is

[swift crag]

The first thing that comes to mind is a state machine to control high-level ideas (going for the enemy flag, attacking the enemy flag carrier, defending the flag) and then behavior trees to implement those ideas

[languid spire]

It's the Unity Machine Learning system

[young fossil]

Also how would I implement behavior trees?

[swift crag]

I haven't done them in Unity (yet). I am actually looking at that right now though.

[queen adder]

what should i do instead of a raycast to find the object to hold

[young fossil]

Didn't know that existed, cool. How long did it take you to cover the API and program it?

[swift crag]

actually, this is wrong

i forgot about Muse Behavior!

(which is only loosely tied to Unity's generative-AI Muse ecosystem)

the name is very unclear

[queen adder]

ohh

maincam.forward

[swift crag]

use Physics2D.OverlapPoint

[languid spire]

honestly, 5 minutes. To get it to 'learn' what I wanted it to learn in the way I wanted, months

[swift crag]

a raycast is unnecessary to detect if you have clicked on an object in 2D physics

[young fossil]

Super cool, I'll look into it thanks

[swift crag]

you aren't shooting a ray from the camera at the object. it's a 2D system.

[queen adder]

yeah

[young fossil]

What is Muse Behaviour?

Can't find info on it

[swift crag]

It's pretty new.

[young fossil]

Is it an extension?

[swift crag]

(and it's remarkably hard to find it when searching...)

[queen adder]

so uhhh

[swift crag]

the thing is that it's barely tied to Muse

you can just ask it to (try to) generate tree elements

[queen adder]

any help with my "2d drag system"

how do i build momentum

[swift crag]

by not setting the velocity every frame...

[queen adder]

i removed the velocity setting

and it just falls faster downward

[young fossil]

That's cool, thanks. As for the behaviour trees, how do you implement the pattern?

[swift crag]

if you don't want gravity, turn off gravity

[cosmic quail]

wait really? physics2d.overlappoint should be used instead? what is the difference?

[queen adder]

i kinda want it to be like the potioncraft drag system

[young fossil]

Is it switches/if statements

[swift crag]

a 2D raycast is not fired from the camera into the scene

[queen adder]

no i like the gravity i mainly want it so i can like fling it across the screen

[swift crag]

Increase the amount of force you apply.

[swift crag]

A behavior tree is basically a sequence of operations

The tree is evaluated from left to right.

[queen adder]

but what im doing is im setting it to a position over and over?

[young fossil]

Yep, this is what worries me, sounds like it would be unreadable by the end of it

[swift crag]

so a very simple tree could be:

• move to target
• attack target

The first action runs until it succeeds, then the second action runs

[cosmic quail]

but is there any benefit to using one over the other? either functionaility or performance wise

[young fossil]

At least with a FSM or Utility system it's very organised in a sense

[swift crag]

Show your current code.

[swift crag]

they're two completely different concepts

a OverlapPoint finds all of the colliders that touch a point

Raycast2D is finding all colliders along a line

[queen adder]

https://gdl.space/iganalevan.cs

[swift crag]

I don't know how Raycast2D behaves if you give it a length of zero

[swift crag]

heldObject.transform.position = mousePos;

well, don't do that

[queen adder]

yeah

but i want a simalar effect to where its on the mouse

yeah

[swift crag]

which is why you're applying force

to move the rigidbody

[ionic plank]

Hello, i have a script in ZoneTime and I want to collect the boolean in the scrpit in Paterne Hole & Enemy 1. Do you know how to do ?

[swift crag]

https://unity.huh.how/references/serializing-component-references

You need to reference the component on ZoneTime

[cosmic quail]

i always thought to click on objects in 2d you just fire a 2d raycast from the camera like you would in 3d. what if your objects have different z values, does overlappoint get the one in the front like a raycast would?

[swift crag]

How would you fire a 2D raycast from the camera?

a 2D raycast has no Z direction

the raycast is entirely in the XY plane in which 2D physics is being simulated

[queen adder]

its not going directly to the mouse tho

[swift crag]

sure, because you have gravity turned on

so it falls down

[young fossil]

@summer stump You reacted to my message, so anything to add to what I said? Truthfully I don't really understand how to implmenent a clean, behaviour tree in Unity, asking here before I delve to research. Any advice?

[queen adder]

wait what happends if i turn off gravity

cause like i like the falling

[swift crag]

then there is no gravity

unsurprisingly

[young fossil]

Pretty much nothing comes up when I search Unity behaviour tree

[queen adder]

i want the gravity tho

[hollow dawn]

My player has some animations. When I move or run or crouch the animations affect the camera as well. How can I make it so the camera still follows the player but isn't affected by the animations? My game is a FPS btw some one please help.

[swift crag]

then don't turn it off

[summer stump]

Behaviour trees can be organized cleanly, and one of the issues with FSMs is that when you increase the number of states it gets very complex fast with all the transitions.

[swift crag]

That is a reasonable idea.

[queen adder]

it doesn't work even with 0 gravity

[young fossil]

Yep, agreed. They are very finite indeed xD

[swift crag]

You're going to need to be much more specific than "it doesn't work"

[queen adder]

https://gdl.space/mamanigire.cs

okay ill record rq

[cosmic quail]

Physics2D.Raycast(Camera.main.ScreenToWorldPoint(Input.mousePosition), Vector2.zero);

[swift crag]

this does not fire a raycast from the camera

a 2D Raycast does hit colliders that it starts inside of

so this will probably work

[cosmic quail]

oh, i thought it did because it looks almost exactly like the 3d raycast function, which does 🤯

[swift crag]

both of them fire a ray from wherever you ask them to

[swift crag]

notice how you're not using the camera's direction at all here

[cosmic quail]

yeah you're right, in 3d it would be transform.forward or something instead of vector2.zero

[swift crag]

you're immediately dropping the object

as I said earlier: you should use GetMouseButtonDown to check for an object when you click

[queen adder]

im holding the mouse button tho

[swift crag]

so what? your mouse went off of the object

also, this raycast is still wrong

[queen adder]

okay how do i fix the raycastr

one thing at a time

[swift crag]

by getting rid of it

[queen adder]

done its gone

[young fossil]

https://ktmarine1999.medium.com/behavior-trees-in-unity-20a738b5508c
Opinions on this implmentation?

[swift crag]

https://docs.unity3d.com/ScriptReference/Physics2D.OverlapPoint.html

use this to look for a collider wherever the mouse is pointing

[queen adder]

how would i do that

[young fossil]

Seem complicated and an effort to learn, so making sure it's worthwhile

[cosmic quail]

wait so if your objects can have different z values in 2d, do neither methods work? because they both check z 0 only?

[swift crag]

Collider2D hit = Physics2D.OverlapPoint(mousePos);

that's it.

[swift crag]

2D physics mostly ignores the Z position of objects

I know that you can use depth to do filtering

I haven't used that before.

Although the Z axis is not relevant for rendering or collisions in 2D, you can use the minDepth and maxDepth parameters to filter objects based on their Z coordinate. If more than one Collider overlaps the point then the one returned will be the one with the lowest Z coordinate value. Null is returned if there are no Colliders over the point.

[cosmic quail]

oh ok, so by default it always returns the object with the lowest z like i expected it to, thats good

[swift crag]

this is from OverlapPoint, mind you

Raycast's page doesn't mention this

[glossy turtle]

yeah making a behaviour tree is worthwhile for any game.

[queen adder]

okay so ive changed the raycast to the overlap point

and changed where i use the raycast collider to overlappoint

[young fossil]

Any advantages to the other apporaches?

[queen adder]

but i like the gravity

[young fossil]

FSM, Utility AI

[queen adder]

fine

[glossy turtle]

it depends upon how you will make that tree.

[queen adder]

so when its being held

[young fossil]

Well that's the point of me asking here. I was asking about implementation, never done this pattern before and I would like suggestions on how to achieve a good implementation

[swift crag]

do you know what a behavior tree is

[summer stump]

Don't forget Goap and HTNs, if you're gonna include Utility

[glossy turtle]

i know fen. its used for Enemy AI.

[swift crag]

GOAP mentioned 🗣️

[queen adder]

how do i enable gravity when its done being held

[radiant frigate]

hi! how do i make a reference to a prefab on a script which isnt instantiated at the start of playtime?

[glossy turtle]

it depends upon your programming thats what i can say.

[swift crag]

You need to store that reference when you instantiate the prefab

then give it to whoever needs it

[summer stump]

By dragging it in? A prefab can be referenced by another prefab

[swift crag]

or if you're trying to reference the original prefab, then yeah

just drag it in

[radiant frigate]

the script isnt on a gameobject either, both are just chilling in assets

[young fossil]

I believe my programming is fine, especially when I have a good idea of what I am supposed to be programming; hence my question and purpose of why I am here

[queen adder]

i know how i just think i need to move some things

[swift crag]

I haven't heard of HTNs before. It looks like GOAP with some extra finesse

[eager spindle]

now that I think about it why doesn't unity discern between prefab and gameobject?

[swift crag]

Ooh, I like the look of this

[eager spindle]

they should make prefab inherit from gameobject

[swift crag]

prefabs are game objects

they're an asset that stores a game object

prefabs don't exist in the built game at all

[young fossil]

Because I find very little resources on Behavior Trees in my searches, it's supposed to be "the most versatile" solution yet it seems no information I can find is credible and no one here really knows much about it either

[radiant frigate]

what i mean by this is that i cant drag it in because this is how the inspector looks

[eager spindle]

prefabs aren't attached to a scene, gameobjects are

[swift crag]

This is not a prefab

This is a script asset.

[eager spindle]

which is a difference

[summer stump]

It is not the most versatile solution

[eager spindle]

so perhaps prefabs aren't fully gameobjects and could be abstracted

[golden ermine]

Hello guys I need help, I have this patrolling script in which enemy will go from point to point and when it comes to last point it will just stop. I want my enemy to go back to the first point and start looping and I also want my enemy to face where the point is because now he will just walk backwards to the point that is at the back of him for example. This is script: https://hastebin.com/share/abuwegolov.csharp

[swift crag]

Prefabs are literally an asset that contains a game object, so...

[young fossil]

I'd agree, I read that on a reddit post comparing them. Again, rubbish source of info

[summer stump]

The .prefab asset file contains a gameobject

[radiant frigate]

i know, i want to make a reference to a prefab inside this script asset that isnt in a prefab, thats what i meant, srry if i explained it wrong

[eager spindle]

it would reduce confusion for many if prefabs were different from gameobject

[swift crag]

You shouldn't be assigning anything here at all

[summer stump]

That makes no sense honestly
Prefab is a file extension

[eager spindle]

a lot of people I helped kept trying to change the position of a prefab rather than the gameobject they instantiate

[swift crag]

The default values here are strictly used to give default references when adding a component

[young fossil]

@summer stump @swift crag Thanks both of you still, for giving me leads like GOAP and HTN

If you have any other buzzwords lmk

[eager spindle]

plus I don't understand why someone would instantiate an object already in a scene

[swift crag]

because you want to copy it?

you can instantiate any unity object

[queen adder]

ima go

[radiant frigate]

what do you mean by default values?

[swift crag]

You are inspecting the script asset itself. This is not an actual component. It's the blueprint your components are made from.

[summer stump]

Behaviour tree is simpler than the others, but a bit more versatile than an fsm.
Once you get to utilitit, goap, htn, it is a lot more complex and difficult to set up.
That is what I would say about it. Behaviour tree has the benefit of simplicity but still quite versatile and allowing complex behaviour

[swift crag]

GOAP took me several tries to "get"

I am very interested in this HTN idea now...

[radiant frigate]

oh i just totally missed the bubble reference, i dont know how i didnt see it

[swift crag]

so instead of every task being a primitive, atomic thing, you can have tasks that expand into several sub-tasks

[radiant frigate]

ty fen and aethenosity!

[swift crag]

Currently, most of my atsks are just activities you can perform

like, literal one-to-one correspondence with buttons the player can push to trigger actions

save for "move to entity" and "move to position"

[young fossil]

Utility AI seems more simple, relies a lot of having numerical values to determine the priority of tasks. I feel like that could work well with an overarching FSM, so you have States like "Fleeing", "Engaged", "Advancing", then Utility AI inside those states to priorities tasks

[glossy turtle]

goap was lot interesting few years ago.

[swift crag]

yeah, it's what I was using previously

I decided to try GOAP beacuse of a very obnoxious situation

I accidentally made it so that the enemy was more interested in approaching the player than attacking the player

So they'd just get up in your face and...stand there.

with GOAP, the enemy approaches you as part of a plan to hurt you

[young fossil]

Lmao, so basically it didn't work, GOAP is the solution I should look for?

did you use GOAP with the FSM/Utility or rewrote it

[golden ermine]

[hollow zenith]

Hey, is there a way to create preset for textmesh font settings? Such as size.
I want to make few for Header/body/footer for example

[summer stump]

It is definitely not hahaha. I promise you

Edit: oh, missed the thread.

[languid spire]

just make prefabs

[hollow zenith]

I guess that kinda makes sense, but I found that there is a setting menu with default font size, but it seems to be per font file.

[young fossil]

Come join us!

[golden ermine]

I just followed tutorial

[hollow zenith]

https://i.gyazo.com/a1d89836b73a0ddd9297c930b521cf49.png
Do you know how to use those?

It's basically what I want, without having to make prefabs

ah its a dropdown under text field

[languid spire]

not used them but they are obviously scriptable objects so you use them that same way

[hollow zenith]

They arent meant to be used that way, its a built in feature.

https://i.gyazo.com/561822700bde38d3c5ec691772f964c5.png

[glossy turtle]

it looks like a scriptable object.

[languid spire]

you are missing a class declaration

where does the word class normally appear in a script?

[rich adder]

have you tried actually putting these methods inside a class 😐

time to do basic c#

methods belong in classes/structs

[glossy turtle]

did anyone tried goap before other than @swift crag

[radiant frigate]

im trying to make a reference to a prefab inside of a script asset that isnt atached to anything at the start of runtime but whenever i try to instantiate it, it says that the object is null

the left screenshot is for reference of what it looks like, completely different to this scripts for example

[glossy turtle]

you can do something bubble =instantiate(someprefab);

in start

[rich adder]

don't randomly tag someone not in active conversation

[radiant frigate]

hi navarone!

[glossy turtle]

right novarone.

[radiant frigate]

what do you mean by this?

[rich adder]

dont change the values on original Prefab

change the copy you get from Instantiate

[radiant frigate]

i dont want to change the prefab in any way

i just want to reference it

[rich adder]

but you are

[radiant frigate]

where?

[glossy turtle]

make a gameolbject for prefab also.

[rich adder]

actually nvm

you got a copy of this script somewhere

[radiant frigate]

i alr have it

[glossy turtle]

i mean in code.

[radiant frigate]

that?

[rich adder]

@queen adder <@&502884371011731486> is spamming nsfw invite links, but it got deleted might want to keep an eye on this account though

[glossy turtle]

[serializedfield] private gameobject prefab;

[fickle plume]

Yep, bot autodeletes them. Just not always as fast.

[radiant frigate]

i think i dont since its a script that should get added to the player once certain ifs are met

[rich adder]

did you read what I wrote

[rich adder]

search the hierarchy to make sure
t:BubbleScript

[glossy turtle]

[serializefield] private gameobject bubble;

bubble =instantiate(prefab) in star

[rich adder]

hows this change anything?

[glossy turtle]

and use bubble for instantiate

[rich adder]

they literally instantiating a Null object

more likely its a copy with prefab not assigned

[radiant frigate]

what is t:BubbleScript

[glossy turtle]

its like you are not instantiate null but using the object for instantiating prefabs

[radiant frigate]

i checked and i didnt found a copy of the script nowhere

[swift crag]

searching for t:foo finds everything with a foo component on it

[ember gate]

hi could anyone help me, how do I delete an enemy when I run over them for context my game is a small car that is drifting and waves of enemies come but only way to kill them is by getting them ran over

[rich adder]

show where you put this script on, the object

[glossy turtle]

it will not give null refence

[rich adder]

instantiating a prefab that isn't assigned should surely give a Null ref

[rich adder]

first define what it means to be "inMotion" to kill enemy

[radiant frigate]

on the player

[glossy turtle]

yea thats the difference making the object not null in start and using the object for instantiation thats what i mean did you understood.

[radiant frigate]

but only after this:

[rich adder]

screenshot it

[ember gate]

for now I only want the enemies to get killed when the car hits their collision box

[rich adder]

so whats the problem ?

[rich adder]

seriously lol

[ember gate]

did this but does not work

[rich adder]

You dont see anything wrong here?

[radiant frigate]

i see that bubble is none

but thats my problem since the start

i dont know how to reference it

[polar acorn]

The Three Commandments of OnCollisionEnter2D:

1. Thou Shalt have a 2D Collider on each object
2. Thou Shalt not tick isTrigger on either
3. Thou Shalt have a 2D Rigidbody on at least one of them

[rich adder]

drag n drop the reference in the slot

aint that diffcult

[radiant frigate]

but i can only do that in run time

[polar acorn]

why

[rich adder]

why

[swift crag]

why are you doing anything other than trying to drag the reference in

[radiant frigate]

because it isnt atached to anything until some ifs are met in runtime

[swift crag]

what isn't "attached to anything"?

[radiant frigate]

the script

[swift crag]

the prefab that Bubble Script is on?

[polar acorn]

A prefab always exists

[swift crag]

so what? prefabs can reference other prefabs, as you've been told already

[polar acorn]

You're trying to reference a prefab, right?

[radiant frigate]

no, the script nor the bubble

yes

inside a script that isnt atached to anything

[glossy turtle]

if you want it to be done runtime then create a gameobject with find search tag.

[polar acorn]

So then how is it doing anything at all

[rich adder]

youcan put prefabs inside, they are just assets that live on your HDD

[swift crag]

You need to show us exactly what "a script that isnt attached to anything" means, because I don't understand what you're talking about

[ember gate]

love this explanation thanks only problem now is that the object that gets destroyed is my car not the enemies but imma fix that in a sec and come back if im dumb and did not manage that

[radiant frigate]

because it gets atached to a gameobject when certain ifs are met

[polar acorn]

You cannot find a prefab with a tag

[rich adder]

please refrain from giving random suggestions that have nothing to do with the problem at hand

[polar acorn]

Ah, okay. So then you'd want this script to reference the prefab you want, and pass that to the script you've just added

[swift crag]

Right.

That makes sense now.

You'll be instantiating the prefab with the BubbleScript on it (and parenting it to the player)

[radiant frigate]

srry im not english native so i may not use the best words to formulate my phrases

[radiant frigate]

the prefab has a script that makes it destroy after 10 seconds

[swift crag]

You will have two prefabs.

[swift crag]

• A prefab with a BubbleScript on it
• The bubble prefab

[rich adder]

also why are you calling BubbleProtect with a string

[radiant frigate]

isnt it a coroutine name?

[swift crag]

(you can just do StartCoroutine(BubbleProtect()))

[radiant frigate]

ohhh

[glossy turtle]

its like i am lazy of typing entire code.

[swift crag]

It's different from something like Invoke

where you do have to give it a name

[polar acorn]

This script should have a public field for the bubble prefab.
When you add the BubbleScript component to the player, also set that component's bubble to the prefab you assigned in the previous step.

[swift crag]

Calling BubbleProtect() does nothing on its own. It just gives you an object that you can then run as a coroutine.

[polar acorn]

No one's asking you to type code they're asking you to just stop vomiting alphabet soup that has nothing to do with the problem at hand

[rich adder]

no one needs entire code, nor to they need to be led astray with irrelevant suggestions. Its counter-productive

[swift crag]

This is also a good idea.

[weary egret]

Is this how to link an anonymous account? Getting an error

await UnityServices.InitializeAsync();
await AuthenticationService.Instance.SignInAnonymouslyAsync();
var token = AuthenticationService.Instance.AccessToken;
await SignInWithUnityAsync(token);

[swift crag]

well, what's the error?

you can't just stop at "there's an error"

[radiant frigate]

okay i can try that, it makes sense

[rich adder]

You dont sign in with the Anonymous token

[radiant frigate]

ill notify how it goes!

brb

[weary egret]

What do you mean?

[rich adder]

SignInWithUnityAsync gets the Token from the browser response

[glossy turtle]

fistly assifn something to that gameobject in the start and use it generate instantiation.

[rich adder]

exactly

[weary egret]

So what do I do instead?

[polar acorn]

Please just stop saying random things

You're only confusing people

[rich adder]

and that is def against the rules

[rich adder]

do it properly ?

[polar acorn]

It's okay to throw out a guess when you don't know as long as:
A) You acknowledge it's a guess
B) They're not actively being helped by someone who does know

[rich adder]

where did you follow this wrong instruction from @weary egret

[weary egret]

Yes, that's what I'm asking. What is doing it properly?

https://docs.unity.com/ugs/manual/authentication/manual/unity-player-accounts#Sign_in_a_returning_player_or_create_new_player

I didn't know where it was pulling the token from.

[glossy turtle]

i am lazy in typing.

[buoyant knot]

synnergy

[polar acorn]

Then why type unrelated things at all instead of just not typing

[swift crag]

then be even lazier and don’t post

[rich adder]

I have a video on this exact login mode if you want to use that

Am I helping yet?

[weary egret]

Sure, that'd be great.

[rich adder]

https://youtu.be/XVqYIFcjhLE

[glossy turtle]

thought of helping that guy.

[polar acorn]

Then why post something that has absolutely nothing to do with the problem and is not even remotely a solution

[glossy turtle]

it will give null refence untill you assign something in the start.

[weary egret]

Oh I started using that tutorial, but I couldn't get my setup to recognize PlayerAccountService and I couldn't add using Unity.Services.Authentication.PlayerAccounts at the top. I have the latest version of the Authentication package.

[summer stump]

You did not

[rich adder]

interesting, which version of Unity and Auth are you using ?

[weary egret]

Auth 3.3.1, Unity 2022.3.20f1

[rich adder]

also is your IDE properly configured

[glossy turtle]

ok.

[radiant frigate]

something like this worked

[weary egret]

As far as I know. I'm pretty deep into a project and we are just implementing a persistent log in on top of an existing game.

[radiant frigate]

Thanks to everyone that helped me!

[ember gate]

good now I kill the enemies but i sometimes get stuck in them

[glossy turtle]

i think i was telling you this.

[radiant frigate]

and ty for your patience!

[rich adder]

Oh okay because it should recognize PlayerAccountService

[radiant frigate]

i dont know, what you were writting sounded very ambiguous

but still ty for helping!

[polar acorn]

No, you were saying some random waffle about using findWithTag to reference a prefab

[glossy turtle]

i think he understood and found a solution. its not the way all others understand but if have that thinking you can understand.

[rich adder]

he understood after digi has explained it to them

[glossy turtle]

you didnt understood.

[polar acorn]

They understood other people despite your nonsense, not because of it

[glossy turtle]

anyways. thats it. someone got a solution

[summer stump]

No one could understand. It was ambiguous to the point of nonsense

[polar acorn]

because it was nonsense.

[glossy turtle]

i really dont like typping. i mean typing the entire code for explaining.

[polar acorn]

Then don't

[ember gate]

how do I take the velocity from the carcontroller and check in another code if the velocity is above a certain number to kill monsters or else to not kill

[rich adder]

then refrain from doing so by giving incorrect suggestions

[summer stump]

Please please stop then

[polar acorn]

You can get the Rigidbody component from the object, and check the magnitude of its velocity

[weary egret]

Yeah, VS2022 didn't like it. VS Code is cool with it. Getting a new error.

WebRequestException: {"detail":"external token not provided","details":[],"status":400,"title":"INVALID_PARAMETERS"}

[rich adder]

seems you haven't provided the token now

did you get the Web browser prompt ?

[glossy turtle]

i will type.

[glossy turtle]

i will not.

[frosty hound]

Yes, you will, thanks.

[polar acorn]

Stop trying to answer questions you don't understand when someone is currently being helped. You just make things more confusing for them because they haven't been here long enough to know that you have no idea what you're talking about

[ember gate]

this seems right to you?

[rich adder]

~~if you're using OnCollisionEnter you can use other.relativeVelocity to find the hit velocity. ~~
Oh nvm you're using Trigger

[glossy turtle]

nevermind it kid just understand the concept behind.

[polar acorn]

You need to get the Rigidbody component from the collided object, but if you're specifically checking on OnCollisionEnter then navarone pointed out the shortcut to getting that speed that'll also take this object's speed into account, you should use that instead ^

[summer stump]

Why do you insist on harming others?

idk what is happening here but just stop the beef, i understand both points of view since Ninja_dude just wants to help (or so it seems), and i can understand the point of navarone digi aethenosity and fern because he just confuses the matter more, either way i think there is no real benefit on getting so defensive Ninja_dude to the point where you are just saying childish things like i will type or i dont like to type. besides everything thanks to you all for the help and think about the fact that there is no point in being childish or rude

[ember gate]

just gotta change the value from 10 to like 15 or something

the enemies can jump on me and throw the car away xD when I stay still

[rich adder]

don't use magic numbers, make a variable in the insector so you can change it at runtime

[ember gate]

or move me around

[ember gate]

ye ur right

[rich adder]

are they Navmesh agents?

[ember gate]

no

just some prefabs which spawn from certain spots atm

[rich adder]

how do they move though ?

[ember gate]

wanna see their code?

[rich adder]

sure, just seeing if they move with transform

[ember gate]

photo or code

[rich adder]

use the codeblock

or link

[ember gate]

ok

[rich adder]

but if they move transform , they will inherently push rigidbodies out of the way

[ember gate]

{
    public GameObject car;
    public float speed;

    private float distance;

    // Start is called before the first frame update
    private void Awake()
    {
        car = GameObject.FindGameObjectWithTag("Player");
    }

    // Update is called once per frame
    void Update()
    {
        distance = Vector2.Distance(transform.position, car.transform.position);
        Vector2 direction = car.transform.position - transform.position;

        direction.Normalize();

        float angle = Mathf.Atan2(direction.y, direction.x) * Mathf.Rad2Deg;

        transform.position = Vector2.MoveTowards(this.transform.position, car.transform.position, speed * Time.deltaTime);

        transform.rotation = Quaternion.Euler(Vector3.forward * angle);
    }
}

[rich adder]

yea MoveTowards will just kinda bulldoze its way through anything

[glossy turtle]

no its not childish but i think i should not help over here probably. just watch.

[rich adder]

Maybe use a rigidbody so you can make them be hit /stopped by the car

[ember gate]

they got one

[rich adder]

then don't use transform.position = to move

[radiant frigate]

i dont know, its your choice!

[ember gate]

or wait nvm

[hushed hinge]

https://gdl.space/qonibakecu.cpp the player seems to be still moving when i presses something or when i jump even though i have the time scale on 0

[ember gate]

mb they only have a box collider within the inspector

[rich adder]

timescale 0 doesn't stop Update nor does it Stop key Presses or would it affect any of that

[ember gate]

ive added a rb to every mob

[ivory bobcat]

You may need to show where you're flipping the character

[rich adder]

You need to just disable the movement script @hushed hinge

ideally you make GamePaused a static event

[merry spade]

My Movement is extremly stuttery, I use the character Controller to move in Update() and My camera updates in LateUpdate()

[rich adder]

we cannot know for sure why if you don't provide the rest of the info. How is the character moved

[hushed hinge]

PauseGame to become a static event?

[swift crag]

Events can call methods when they're invoked

So you could have an event called OnGamePaused.

You could then add things to it to have them run when the game pauses

A static event would just be..static!

[rich adder]

I mean have an event so your movement script can be disabled/enabled on pause/unpause

[swift crag]

public class GameController : MonoBehaviour {
  public static event System.Action<bool> OnGamePaused;
}

then...

[summer stump]

Sure

[merry spade]

character Controller this is the Code:
The function gets called every frame in Update
https://pastecode.io/s/1bfxzb4n

[summer stump]

That is a nice way to do it

[swift crag]

public class Something : MonoBehaviour {
  private bool moving = true;

  void Awake() {
    GameController.OnGamePaused += HandlePause;
  }

  void HandlePause(bool paused) {
    moving = !paused;
  }
}

something like this

[rich adder]

have you tried using Cinemachine instead ?

[summer stump]

What is this?

[rich adder]

wait no why are you turning everything static

[swift crag]

You would then invoke the event like so:

[merry spade]

whats cinemachine?

[swift crag]

public void SetPaused(bool paused) {
  OnGamePaused?.Invoke(paused);
}

(this would go in GameController)

[summer stump]

A package from unity

[rich adder]

its a Much better Camera package

[swift crag]

Every method that has been added to the event will run

[polar acorn]

A package that basically makes cameras "Just Work™️" with very little effort:
https://unity.com/unity/features/editor/art-and-design/cinemachine

[merry spade]

But its not the camera that stutters its the player you can see this stuttery thing also in the scene window

[rich adder]

how do you know?

[swift crag]

It could be either, since the camera is moving around

[rich adder]

also you should only call .Move once

[swift crag]

Try viewing it through the scene view

That will let you see which it is

[hushed hinge]

uhh.. is this a separate script?

[merry spade]

Yeah but I mean the scene view is a static camera

[swift crag]

I showed you two different classes, yes.

GameController decides when to invoke the event.

Something is a class that subscribed to the event.

[rich adder]

Something can be your player movement script for example

[summer stump]

You may want to combine the two Move calls, and the lerp is not really how you would want to write it. Keeping a static t parameter is just the same as looking at an offset, but if that's what you want it's fine

[merry spade]

but that doesnt explain why it stutters so much does it?

[hushed hinge]

but it's red underline on gamecontroller

[swift crag]

well, yes, you'd have to actually have a GameController class

[summer stump]

The two move calls might be a contributing factor

[swift crag]

you can't just copy random chunks of my example into your game

[rich adder]

Oh god tell me you're pasting stuff without understanding it

[merry spade]

Ok I will try to combine them

[hushed hinge]

no, I always had this pause script

[summer stump]

The same as always, you cannot ever copy paste from here

[rich adder]

You cannot do that every time we show you an example, you have to attempt to adapt it to your use case

[summer stump]

Then what is gamecontroller?

[rich adder]

if pause is your pausing script then put the event in there, simple as that

the other scripts just "subscribe" if they need to know game was paused

[hushed hinge]

Pause is my pausing script

[merry spade]

Ok I combined them and nothing changed

[rich adder]

alright so put the static event in there

look at the examples Fen wrote
GameController is pause
Something is your PlayerMovement script for example

[weary egret]

Now I did. It goes through and logs me in. The final piece - it asks me to log in every time in Unity editor. Is this okay (like is it an editor only thing) or do I need to check to see if I'm logged into Unity Player Accounts first? If so, how do I do so?

[summer stump]

Ok, well, I don't see much of an issue from the code. Can you share a video of it? .mp4 embeds here

[rich adder]

when you sign in a player for the first time, their Token and Cached data is stored inside PlayerPrefs

[merry spade]

I allready did here:

[rich adder]

You can sign in an already Cached user without signing in again if they already signed in @weary egret

https://docs.unity.com/ugs/manual/authentication/manual/cached-players

[merry spade]

I can make the camera to follow the player without lerping so one can see better if its the camera or the playe

[rich adder]

it should still be something you should do, regardless.
Did you use cinemachine yet

[weary egret]

public async Task InitSignIn()
{
    await UnityServices.InitializeAsync();
    await PlayerAccountService.Instance.StartSignInAsync();
}

Would I do this instead of StartSignInAsync?

[merry spade]

no i didnt because I cant imagine that it cant work with the normal camera

[summer stump]

I see it, just the slight hiccups every so often.

[rich adder]

it can be if camera follow wasnt poorly coded

[hushed hinge]

hmm... the Player2D script do havet he movement script,

Something = Player2D?

[rich adder]

the movement script only care about the event

its static so you dont need any references, you can directly subscribe to it

like pause.OnGamePaused += GamePaused

[weary egret]

@rich adder

public async Task InitSignIn()
{
    await UnityServices.InitializeAsync();
    if (!AuthenticationService.Instance.SessionTokenExists)
    {
        // if not, then do nothing
        return;
    }
    await PlayerAccountService.Instance.StartSignInAsync();
}

If I understand right, this covers what you're talking about here?

[rich adder]

from the docs

If a cached player exists on the SDK, you can link the cached player to the Unity Player Account.

Sign into the cached player's account using SignInAnonymouslyAsync.
Link the cached player's account to the Unity Player account with LinkWithUnityAsync.

For more information about cached players, refer to Sign In a Cached User.

https://docs.unity.com/ugs/en-us/manual/authentication/manual/unity-player-accounts#Sign_in_a_returning_player_or_create_new_player

ops here

[hushed hinge]

hang on, i was doing something, what do you think?

[summer stump]

Show OnGamePaused

[rich adder]

first of all did you add OnGamePaused inside pause script ?

also you dont need public pause Pause

static members live on the class itself not any instances

[weary egret]

Yes, but how do I check if they are connected to Unity Player Accounts or not first?

[rich adder]

pretty sure you can use the token already found to use that
so if token was found use that inside SignInWithUnityAsync

[hushed hinge]

hmmm... no? (i've been searching it up) I have the PauseGame

[rich adder]

searching what up

[hushed hinge]

about OnGamePaused

[rich adder]

there is nothing to search, you're literally adding 2 things

[rich adder]

You can literally call it Waffles

names dont matter

did you add a STATIC event inside your pause script

what did you call it

[hushed hinge]

this is when pausing the game when you press P. PauseGame

[rich adder]

i dont care about that

did you add the event to invoke first
#💻┃code-beginner message

[tranquil hollow]

how can i fix that?

[rich adder]

fix what , what am i looking at

[summer stump]

#💻┃code-beginner message

This is ongamepaused

It is something YOU make. There is nothing to search

If you want to search something, look up events

[tranquil hollow]

the spawn its so random at axle y

[hushed hinge]

right now

[weary egret]

I guess what I am asking is, if I wanted to conditionally have a "Link" button, how do I determine whether the current user is actually linked to Unity Player Accounts or not yet.

[summer stump]

Why are you showing me this?

That is not how you do it at all

[rich adder]

why are you putting the event inside the movement script

[summer stump]

Put the event in the pause script

[rich adder]

you only SUBSCRIBE to it from the movement

[hushed hinge]

isn't Something = Player2D?

[rich adder]

you dont Define it inside the movement script

[summer stump]

See the part where you write pause. ?
That means "from pause"

So put it in pause

[summer stump]

What does that even mean?

[frosty hound]

@hushed hinge make a thread

[rich adder]

seriously how did you get this far and dont know you're obviously missing it inside the pause script

thats why its red..

[hushed hinge]

Pause

[stuck palm]

anyone know how to do jump through platforms?

[stuck axle]

I'm using an existing project as a template to get started, and I'm at a loss for why they have basically 3 different coordinates/locations stored for entities. the built in transform.location, then another separate Vector3, and then worldX/worldY ints. Is this just straight up bad code or is there a possible reason why? It's a paid asset so I dont think I can share the code. Its simple though, nothing crazy going on.

[rich adder]

i was working on an example I can show you idk if its the best way to do it though

[polar acorn]

https://docs.unity3d.com/ScriptReference/Physics.IgnoreCollision.html
Ignore platform colliders above you, un-ignore platform colliders below you

[rich adder]

interesting method digi suggested, should try that. (oh actually I had it in the code but for some reason commented out lol)
I'm basically using Dot product though, so might not be the most reliable

[swift crag]

Do you use a physics query to look for "relevant" colliders?

i guess i'd check a sphere that's a bit larger than the player

[rich adder]

thats what I do, but my method is not good now that I think about it. it makes whole platform trigger which is bad for others standing on it

 if(currentPlatform == null)
 {
     var hits = Physics.OverlapSphereNonAlloc(transform.position + headOffset, radiusCheck, hitCols, platformLayers);

     if (hits == 0) return;

     currentPlatform = hitCols[0];
     currentPlatform.isTrigger = true;
 }```

[swift crag]

I wonder what the cost of IgnoreCollision is. It can't be as fast as a layer mask!

(not that it's a problem; i'm just curious)

[stuck palm]

 public bool IsColliderValidForCollisions(Collider coll)
    {

i feel like i could use this from the kinematic character controller

[polar acorn]

Since it's for a Smash-like, I actually had the Stage object that had a list of all of it's pass-through colliders and their bounds. After the character moves, I just ran a check that looped through the list of pass-throughable platforms for ones whos tops were below the player's bottom and enabled collision, and vice-versa for ones whos bottoms are above the player's bottom

[rich adder]

i feel like KCC has an example on jump through platforms no ?

[stuck palm]

actually maybe, i havent checked

how can i check what layer a collider is on?

[swift crag]

grab the layer property from its gameobject

note that this is a layer index, not a layer mask

[stuck palm]

thats fine

[rich adder]

https://unity.huh.how/bitmasks#checking-if-a-mask

you can check if certain layer on collider matches a certain layermask

[stuck palm]

oh thats good actually i have a ground layermask on this script anyway

i'll just use that

how do they turn a layermask into an int

[rich adder]

layermask.value

so basically layerMask.value & (1 << obj.layer)) != 0

[magic panther]

Update Function --> https://hatebin.com/piwccqgoqu

So the trampoline is not getting detected, even with is Trampoline and other things gpt and intelli suggested. What am I getting wrong here?

[polar acorn]

Try logging onGround and what object the raycast hit to find out what isn't happening that you're expecting to happen

[magic panther]

ok, one sec

ooooh

it detects the literal object

not the wrapper

so TrampolineObj. Do I just change the name?

how would I even check if that got detected

[swift crag]

a Collider can never be a TrampolineObj

the is operator is used to check if an object could be assigned to a variable of a specific type

[magic panther]

do I just give the trampoline object itself a collider??

[swift crag]

TrampolineObj isn't even a type here. It's the name of an object in your scene

[magic panther]

what's the best way to do this

[swift crag]

you would still have the same problem, since this code doesn't make sense

[polar acorn]

What is the relationship between the object with the collider and the object with the component you want

[swift crag]

what you can do is check if the object you hit has a component

[magic panther]

+ change the code

[stuck palm]

Does on Trigger Enter require a rigidbody

[magic panther]

apply the script to the trampoline obj, yes?

[swift crag]

It requires one somewhere

[swift crag]

If you put the collider on the same object as the Trampoline component, you can do this:

if (groundHitInfo.collider.TryGetComponent(out Trampoline trampoline)) {
  // do stuff with the trampoline variable
}

[stuck palm]

if i have one rigidbody on the root object, do i need one for the colliders of children in that object?

[swift crag]

No. A Rigidbody makes use of all of the colliders on objects that are parented to it.

[stuck palm]

okay, thank you

[swift crag]

Note that for triggers, OnTriggerEnter is sent to both the object with the collider and the object with the rigidbody

This isn't the case for collisions. OnCollisionEnter is sent to only the object with the rigidbody

[stuck palm]

thats fine, thank you

[magic panther]

alright, worked. Thanks guys

[cosmic dagger]

might help to have an explanation in case people can't see what the problem is . . .

[fervent abyss]

how can you not see the problem 😭

ok

explained

uwu

[rich adder]

z fighting maybe?

[fervent abyss]

huh

[cosmic dagger]

i see moving back and forth while trying to look at a screen?

[rich adder]

try putting the text slightly more forward than screen

[fervent abyss]

same thing unless i look at certain angle

[summer stump]

Can you show the hierarchy?

[rich adder]

whenever you pop that multiplayer image thats when issue occurs

[fervent abyss]

oh yes

when i disable it everything works fine

but i need the image

:(

[rich adder]

well now you know where to check for problem area, narrow down the issue

[fervent abyss]

oh wait

i can just

use a plane with image

💀

[rich adder]

wouldn't it just be easier to use World Canvas ?

[fervent abyss]

huh

[summer stump]

With panels and the image on it

[summer stump]

A canvas set to worldspace

[fervent abyss]

it is

[rich adder]

its not , at least not the text you have selected there

that looks like a sprite/mesh

[fervent abyss]

the image is a sprite.....

[rich adder]

then why are you mixing Sprite Renderer sprite and UI

ui uses Image component

sprite renderer uses meshes with sprite

[cosmic dagger]

if you're creating any type of UI, use a canvas . . .

[fervent abyss]

i have a canvas

[fervent abyss]

i am using that

[rich adder]

let me see the inspector

[fervent abyss]

i kinda deleted it already and made a plane with image :3

too late!!!!

but thanks!!!

[stuck palm]

i made it so there are colliders in each limb. problem is now, each limb detects their own hit, so how can i stop this from happening?

[wintry quarry]

Hit from what

[fervent abyss]

if you mean colliders hitting each other use layers

make so same layers dont collide

[wintry quarry]

Well if they're part of the Same Rigidbody they won't collide with one another no matter what

[stuck palm]

from another player,

[stuck palm]

they arent hitting each other

[wintry quarry]

Use a separate collider for inter-player interaction

Use layers to separate everything

And layer based collisiona

[stuck palm]

wdym? the colliders arent hitting each other, the problem is collisions from another players move hitbox. I seperated out the colliders into seperate limbs to make the collisions feel more accurate and tight

[wintry quarry]

Yes and you need to use layers to make those things not interact

The move hotboxes and these colliders should go on different layers and not be set to collide in the matrix

[void thicket]

If you have single rigidbody it should report collision once tho?

[wintry quarry]

Maybe I'm not understanding the problem

Is the problem that you're getting multiple collisions? Or is it that you're getting any collisions on these at all

You'll get one OnCollisionEnter per collider pair that touch

[void thicket]

Rigidbody pair no?

[wintry quarry]

Collider pair AFAIK

That's how it works for triggers

[stuck palm]

hold on i'll get a screenshot, unity just crashed

[swift crag]

I don't know what happens if you have multiple trigger colliders under a rigidbody

[void thicket]

You'd get additional info in contacts in Collision if multiple contact between same rigidbodies
Not sure if that triggers event methods, hm

[swift crag]

oh, wait, that's the problem :p

so I dealt with something like this while working on a soulslike

[stuck palm]

problem is im getting multiple collisions under one rigidbody, i just want one

[swift crag]

You can't avoid multiple collisions. You can change how you respond to them, though!

[wintry quarry]

That's for multiple contact points in the same Collider pair. Otherwise how would this work https://docs.unity3d.com/ScriptReference/Collision-collider.html

[swift crag]

I made Hitbox and Hurtbox components that report impacts to the entity

[wintry quarry]

Then disambiguate it in your code

If you are already touching the Rigidbody ignore the collision

[swift crag]

the entity would ignore hits that were not stronger than a previous hit

[wintry quarry]

Just track which bodies you're touching.

[swift crag]

er, or did I do that on the weapon side? I might have done that on the weapon side

[stuck palm]

unity crashed again bruh

[eternal needle]

I did it from the weapon side, and you can simply store the rigidbody in a hashset to know if you've already hit the object.

Clear the hashset everytime you want a new instance or tick of damage

[swift crag]

yep, that's what I was doing

the weapon knew "hey, I already got a hit of quality 0.75, so this new 0.5 quality hit shouldn't even do anything"

and a 1.0 quality hit would produce another 0.25 damage

that way, clipping an enemy's "weak" hurtbox before whacking their "strong" hurtbox wouldn't make you deal more or less damage than just hitting the "strong" hurtbox

[stuck palm]

basically imagine a move hitbox that was about this size. all the overlapping body colliders recognise it and all tick the same damage

[swift crag]

lest you wind up with a dog that deals 11,640 damage per second

[stuck palm]

i just want it to tick the damage once

[swift crag]

yeah, so you need to abstract this

Each collider should not be directly causing damage to be taken

[stuck palm]

public class LimbCollider : MonoBehaviour
{
    [SerializeField] private PlayerHit _hit;
    private void Awake()
    {
        _hit = transform.root.GetComponentInChildren<PlayerHit>();
    }

    private void OnTriggerEnter(Collider other)
    {
        _hit.HandleCollision(other);
    }
}

each collider has this script on it

[eternal needle]

Read the convo slightly above that image on a solution. Your colliders shouldnt be looking for things that damage it. It should be told it's taking damage

[void thicket]

Seems right, got confused since each contact also has Collider info
Looks like that is in fact just duplicated info lol

[stuck palm]

what does disambiguate mean in this context?

[void thicket]

Just ref-count your collisions

[swift crag]

to get rid of an ambiguous situation

if you get four trigger overlaps, it's unclear how much damage should actually be taken

the individual LimbColliders cannot make this decision

[golden blade]

hello, if I make a new scene in unity and have a camera displayed for that scene in a different scene through a render texture would this work ?

[formal venture]

can anyone explain to me what that thing means and does exactly?

[void thicket]

() => is lambda expression and += is subscribing to the event

[eternal needle]

Is that lambda even needed?

Looks like it can just directly subscribe

[stuck palm]

what makes this decision then? should it be like a collision manager in this object, or should it be the other player making that damage decision?

[formal venture]

okay thanks

[swift crag]

see the above conversation

#💻┃code-beginner message

[stuck palm]

okay

shouldnt be too hard to refactor

this whole time cus i had a single collider i was making the decision from the victim

[wintry quarry]

Alleviate the uncertainty that comes from multiple collision callbacks

[short hazel]

For completeness, lambda expressions are methods (like void Start()) which don't have a name and can be declared in-place.
Your code is an equivalent of:

button_exit.clicked += ExitGame;
// later...
void ExitGame()
{
    SceneManager.GameExit();
}

[formal venture]

thanks now im slightly less stupid :>

[karmic kindle]

I'm trying to move the camera forward the direction it's facing, but when it's tilted up/down, it will move on the Y axis - how can I get that to stop happening? I found a forum that said to use Normalize()

transform.Translate(Vector3.Normalize(new Vector3(Camera.main.transform.forward.x, 0f, Camera.main.transform.forward.z)));

[willow scroll]

So, you can subscribe to the event only if the method you're subscribing has the same number and type of parameters as the event.

public Action OnSomething;
OnSomething += Update; // works

public Action<string> OnSomething;
OnSomething += Update; // error
OnSomething += _ => Update(); // works

public Action<string, string, string> OnSomething;
OnSomething += Update; // error
OnSomething += _ => Update(); // error
OnSomething += (_, _, _) => Update(); // works

Note that the lambda subscriptions cannot be unsubscribed.

[eternal needle]

Normalizing just scales the vector so it's magnitude is 1. The forward should already be normalized. Add some debug drawrays to see where it's trying to move because this code looks fine if you want 0 y movement

Oh actually you might need to use Space.world in the 2nd paramter, I believe it might be using local space here

[willow scroll]

transform.forward moves the transform in the forward direction they're currently facing. Yes, if it's tilted up/down, your forward is going to be up / down.
If you want to move the camera forward regardless of their direction, use Vector3.forward

[lusty nest]

hey guys i was wondering, how do i detect the force applied to a gameobject?

[void thicket]

Normalizing without Y is fine, though not in readability wise.
However Transform.Translate is local space by default but you are dealing with world space coords
