It's too large - use a website

rich adder
#

did you read about Large Code Blocks

normal smelt
#

well its loading (bad connection)

#

oh its done i will read it

#

is it right?

rich adder
#

yes

normal smelt
#

yeaa, so as i said i get this error everytime

rich adder
#

which error? i missed that

normal smelt
#

is the "not loaded"/"is loading" an error?

rich adder
#

maybe, I never seen it .
do you have actual errors in console ?

normal smelt
#

no there is no errors, but its takes way too longer to load scenes

rich adder
normal smelt
#

the loading is working but for example is make other script not working properly during the loading

#

like, cinemachine confiner2D not working during the loading

vernal minnow
#

is there a way to move the camera relative to the player? so that if the player is so far a certain way, camera moves to show more of a map? currently ive only gotten it to move with the player directly or only the camera moving

normal smelt
#

no the camera just ignore bounds

#

and after the loading is finished, everything become norlam

vale karma
#

i think cinemachine can help

#

add your player to the follow target part of the cinemachine component

normal smelt
#

and thats why i want to get rid of the "not loaded" "is loading" bug

vernal minnow
vale karma
#

theres a ton of features that allow what your lookin for, a simple tutorial about the cinemachine would help too. I mainly do 2D rn tho

vernal minnow
#

im using 2d so if cinemachine would work, then thx man

normal smelt
#

so can anyone help me?

vernal minnow
#

not loaded/not loading error?

normal smelt
#

yea

vernal minnow
#

why is your scene dont destroy on load?

#

i though that was only for gameobjects

normal smelt
#

its not in don't destroy on load

#

look at the screenshots

swift crag
vernal minnow
#

i am, im guessing ya are reffering to the not loaded scene

vernal minnow
swift crag
#

the scene is special: it's never unloaded

vernal minnow
#

interesting

swift crag
#

That's one application, yes.

#

I load a few singletons into that scene when my game starts

#

game controller, main menu...

vernal minnow
#

stupid question, but did you try opening the nonloaded scene?@normal smelt

normal smelt
#

huh no but i will try

#

ok its just freeze the editor during the loading so i can't open it

vernal minnow
#

hmn...

limpid shoal
#

I have a problem, I made a script so that whenever my enemy square touches the red lava or dies it destroies the enemy game object so that it is gone, and when it dies for some reason this error spams my console. Idk what I added or didnt add to my script that it happens so yeah. Could someone help, thank you!

#

i have a similar error where a script checks for an object even after it is destroyed

eternal needle
#

You should turn on error pause though

#

how do I use transform.forward if im reading a vector3. Not sure how to combine the information (so i can move accounting for rotation)

mhyhh.JPG
vernal minnow
#

he could replace the object after it is destroyed in a new location if the object needs to be out of the players way or return it to where it was

im getting an error randomly saying i cannot reparent window to suggested parent. Window will not automatically close. So i the issue is i am trying to click on the text input field of a button and its not letting me

winter prawn
eternal needle
true pasture
#

like I don't understand what the docs say that does

rocky canyon
#

it deals with world vs local space

eternal needle
true pasture
#

okay and world space accounts for rotation youre saying

#

i still dont understand what the function does. Does it return something?

rich adder
#

I think what i sent should work

#

transform.forward * myDirection.y * speed * Time.deltaTime

true pasture
eternal needle
#

Yea it returns the vector in world space. Or just do the other equation I sent and rotate the vector. This will have the same affect

rocky canyon
#

the signature tells ya everything..

rich adder
rocky canyon
#

it takes in a vector3 and spits out a vector3

hello!
why is this always logging the size of the array instead of the index of the button in the array?

#

Hey everyone, i have gc allocation each frame from my camera, even though i deleted all other cameras. why is this happening?

rich adder
swift crag
#

but, to an outside observer, the direction your arm is pointing depends on how your body is rotated

eternal needle
swift crag
#

TransformDirection converts from your point of view to the world's point of view.

languid spire
rocky canyon
#

North is always North.. thats world but if u think of ur facing direction as being north no matter how your facing thats local

swift crag
rich adder
swift crag
#

It's a common error. As Steve said, you can fix this by creating a new local variable inside of the loop that you assign nr to

#

and then capturing that variable

eternal needle
swift crag
#

the function itself, plus references to any in-scope variables the function uses!

sullen zealot
#

it worked thanks

image.png
eternal needle
true pasture
#

I guess I dont understand how to call it. I can't just call TransformDirection as a function. I have to have a transform.TransformDirection(myDirection) but what transform do I use?

#

if it returns a vector why does it need to be called that way?

swift crag
#

TransformDirection is a method on Transform.

normal smelt
#

i guess its a dead end for my game...

swift crag
#

It uses the position, rotation, and scale of the transform to decide how to convert from the transform's local space to world space.

#

It takes in a direction and returns a direction.

eternal needle
swift crag
#

A direction is represented as a Vector3.

# 
Vector3 worldVec = transform.TransformDirection(localVec);

Hey, I have a gameobject with 2 components
One is the logic component and the second is the rendering component
On the renderer's Awake I initialize a variable as the first component by using board = GetComponent<Board>(); and I do get the object

Then I added a OnPointerMove event but on the first frame of the game, the board is null.
Does anyone know why this happens?

swift crag
#

make sure the error is coming from the component you think it's coming from

#

after the error is thrown, click once on the error in the console. this will take you to the object that caused the error.

rugged aspen
#

Ah thanks, it's not the first component lol

true pasture
#

okay thanks guys that cleared it up and its working.

#

im just trying to figure out why this is causing gc alloc. I have only one camera in the scene

swift crag
#

i don't think having multiple cameras would be very relevant

eternal needle
#

from seeing online, apparently this was an issue with multiple cameras at one point a year ago

swift crag
#

ah

eternal needle
#

maybe depends on the version you're on?

paper rover
#

id read up on this issue before and it says it happens with multiple cameras

short hazel
#

A string is created to store the render target's name. It's 184 bytes and very negligible

#

Why do you even worry about that

swift crag
#

I could believe that, with several cameras, they'd need to pick different render targets or something

paper rover
#

yeah maybe, but even after deleting the extra cameras its still causing gc alloc

eternal needle
#

hm they said this was every frame

swift crag
#

profiler from my HDRP game

paper rover
#

hm. thats what i would expect from my URP project

#

but for some reason its 470B lol

#

every ~15 seconds my game would force garbage collect

#

and freeze up

eternal needle
#

do you have incremental gc on? mine wasnt on by default but that should fix the freezing

swift crag
#

my game controller is creating 5KB of garbage per frame. oops.

#

I had a very weird problem: on the Steam Deck, IMGUI text didn't work

paper rover
#

i do have incremental gc on, but wouldnt everything get messed up if i dont?

swift crag
#

apparently the default font asset was busted on linux for some reason

#

my solution was to set GUI.skin.font = font; (amongst other things) in OnGUI every frame

#

i...think i'll make that happen once

swift crag
#

It does have a bit of a performance impact, iirc

paper rover
#

maybe i can manually set GC times, i can try that out

eternal needle
#

it does really help against those freezes, im surprised you have them with it turned on

paper rover
#

where in unity do i turn off incremental gc?

eternal needle
paper rover
#

ah, i think i can manually turn it off and on during runtime too

eternal needle
#

i dont think thats something you would want to do if you can

#

You might need to profile more to see whats really causing the issue. if you have it on, you shouldnt be getting freezes like that

paper rover
#

ill look into it more. i appreciate the insight

tacit estuary
#

Yep that would be correct

lusty girder

Would anyone know why my gwh.WaterHeightAtPosition(floaters[i].position); in https://pastebin.com/gqgzUiyf keeps returning 0 instead of returning different values based on floaters[i].position?
Other script: https://pastebin.com/S74k33Li public float WaterHeightAtPosition(Vector3 position) is the block of interest there

frosty hound
#

Probably because your raycast to determine the wave height isn't hitting anything. Or the position you have your water plane is 0.

#

And seeing as you're making water/waves, it's probably important to mention that displacing the vertices to make waves will not physically move the mesh, it's just visual.

sharp wyvern
#

^ assuming your using a vertex-displacement shader to make the waves, I agree. If not, tell us more about the water/waves mesh- esp. does it have a collider? what kind? @lusty girder

oh okay sorry and thank you for the info

vale karma
#

Im trying to make a point light not light up the inside of a wall. I want it just to affect the ground and ceiling for shadows

#

I see a shadow component but its not doing anything at 1 intensity

swift crag
#

You may be able to use Light Layers to control which renderers are affected by the light.

#

What render pipeline are you using, and is this 2D or 3D?

vale karma
#

URP 2d

swift crag
#

ah, I'm not familiar with the 2D renderer, if you're using that

shell sorrel
#

you are loading a sprite, the stuff you show in resources looks like prefabs

tawdry totem
undone rampart
tawdry totem
swift crag
#

You can load a prefab by the type of any component that's on the root of the prefab.

shell sorrel
swift crag
#

Right.

#

So you could load it as a GameObject (that's what the prefab actually is), as a Transform (because every game object has a transform), or as any component on the root object.

#

You could not load a Sprite because that's not a component type.

#

If you want to load a Sprite, you must put sprite assets in the Resources folder, rather than prefabs that happen to use the sprites

#

this prefab uses a mesh, but it's not literally a Mesh

image.png
rocky canyon
#

wouldnt u need to snapshot the prefab to create a texture from it

tawdry totem
#

how do i put the here properly?

swift crag
tawdry totem
swift crag
#

in that case, GameObject would be a valid type to load them as.

#

If you actually care about the components on the prefabs, use something more specific.

#

but if you're literally just creating a copy and sticking it on the screen, GameObject is fine

#

I think it would be better to just load a Sprite and display that in your UI, though.

#

rather than creating a whole new object that shows a sprite

rocky canyon
#

^ i was gonna say why is this so complicated

#

weapon -> sprite that goes with weapon

#

etc

low drum
#

can someone help me im having an issue with my code ?

rocky canyon
#

dont ask to ask

swift crag
#

just ask (:

low drum
#

oh excuse me, its just that i just set the animation for my sprite and when i do that i can't even move it just play the animation

rocky canyon
#

u want to use a parent container to move around the object,

  • the animation happens on its own object within the parent container..
#
  • you move around the root object (the parent container)
    • the graphics will follow along and animate within its own container
low drum
#

excuse me but i don't really understand.. what do i have to do ?

steep thistle
#

how would i call another script from another? for example, I want to call Connect(); on onCollisionEnter(); but Connect(); is in another script. How would I gain access to this?

vale karma
#

@Fen found it, its a Shadow script you need to add to your objects and then check shadow on the light.

swift crag
#

you have to move the object yourself

rocky canyon
#

your animation is Nested within a different object.. that way the animation doesn't affect the outer object at all..

fast moon
#

My player glitches through objects can someone have a look at my code

rocky canyon
#

you move that outer object around (using code or w/e) and the animation just follows along

fast moon
# fast moon My player glitches through objects can someone have a look at my code

this should be the same as from Sebastian Lague tho it doesnt seem to work

rose galleon

hey, anyone knows what this means? "Assets\Scripts\MC_Movement.cs(39,10): warning CS8321: The local function 'OnCollisionEnter2D' is declared but never used"

Heres the code:
void OnCollisionEnter2D(Collision2D collision)
{

{
Debug.Log("Passou");
}
}

shell sorrel

#

Adjust the { } so they're correct

rocky canyon
#

move an object around the character

#

the character animates on its own object, u move the parent... the character then has to follow even if it is animating..

rose galleon
rocky canyon
#

and another thing.. if u want to move the character with code.. like ur script.. u need to make sure that Root Motion is turned off

#

Root motion means that the animation controls the movement.. it will override ur movement code

low drum
low drum
rocky canyon
#

check out this video, should show u where it is.. and why/what it does what it does

low drum
fast moon
#

oh the speed

#

was too high

rocky canyon
#

most game animations are done the first way..

  • the character is actually animating (in place)
  • then you move the parent around

when these are combined it makes it appear the character is actually walking.

#

if you use root motion

  • the animation actually controls the movement
  • your script will be overwritten by the root motion
swift crag
#

i'm trying to use root motion for all movement at the moment

#

it's a pain in the arse to get it feeling good lol

rocky canyon
low drum
rocky canyon
#

whats the advantage to that?

swift crag
#

you get very accurate movement

#

I might try a motion matching package. That'll be fun

rocky canyon
#

i would actually guess the opposite..

#

when you move with scripting, you can get better/ accurate feeling..

swift crag
#

but yes, it's relatively clunky feeling

rocky canyon
#

only the animation may not match the movement as well

#

if ur trying to get the visuals looking the best.. i guess root motion is the way to go tho

swift crag
rocky canyon
#

ya, i see what ur saying

swift crag
#

instead of having small clips that you explicitly blend between

rocky canyon
#

i prefer having that finite control, even if my animations dont match exactly

#

but again "arcade" prefix 😈 lol

ik but like where do they get initalized

reflection

rocky canyon

get the parameter count animatorReference.parameterCount
then use a for loop to loop thru it
AnimatorControllerParameter parameter = animator.GetParameter(i);
check if its a bool and whether its true
if (parameter.type == AnimatorControllerParameterType.Bool && animator.GetBool(parameter.nameHash))

shell sorrel

if you mean how its called, its implicitly called by unity using reflection

i dont know if any of that is correct, just looking at random stack pages where people try the same thing

#

Unity's physics engine continuously checks for collisions and interactions between colliders. It uses algorithms like bounding volume hierarchies (BVH) or other spatial partitioning techniques for efficient collision detection.
When a trigger event occurs, Unity calls the appropriate method, such as OnTriggerEnter, OnTriggerStay, or OnTriggerExit, depending on whether the objects just entered, are staying inside, or just exited the trigger zone.
The collider information of the other GameObject is passed as a parameter to the callback method (Collider other). This allows you to access information about the colliding GameObject, such as its name, tag, or other components attached to it.

if (Input.GetKeyDown(KeyCode.LeftShift) && Input.GetKeyDown(KeyCode.W))
{
Debug.Log("SPRINTING!!!"); // <-------------------------------------------------------------------
controller.Move(move * sprintSpeed * Time.deltaTime);
}
else
{
Debug.Log("WALKING!!!"); // <-----------------------------------------------------------
controller.Move(move * speed * Time.deltaTime);
}

#

that is outputted even when I dont press anything

#

could it be that the code is triggered by the mc just standing on the terrain?

mental palm
#

yeah because you are checking if the butons are pressed and if there not the lower if statement gets called makes sense

rocky canyon
#

this would make more sense to me

mental palm

youd have to put a "else if" to still check for the walking button

first check if ur even press W.. (if you are.. then check if the shift is pressed along with it)

#

teh structure of the if conditional and the usage of the && would make it so just a single else isnt enough, you'd atleast need a else if and another conditional to capture just the W being pressed w/o the shift

I have this code that is an offset for a flashlight for a player. I made the player flip using the .Rotate. How do i get the flashlight to stay in front of the player?

why not parent the flashlight to the player as opposed to setting the position each frame?

going to go with you setting references to similar slots

but why guess when you can debug.log()

you should be able to see it though being parented on the canvas so why dont you expand that

yea ive expanded the canvas, the parent is being set correctly but wdym by setting reference to similar slots?

Always research before asking here

gritty notch
timber tide
#

so
Start drag -> copy image to dummy gameobject and hide current slot image then enable dummy slot object
End drag -> copy data over to new index which shows new item sprite, disable dummy object

gritty notch
#

also do u have a grid layout component in each slot as well?

gritty notch
timber tide
#

I dont move any slots, they are always there

#

the dummy gameobject is just a visual

gritty notch
#

yea me neither the way i have it setup is a prefab which gets instantiated when an item is added to inventory and that is then whats being dragged and dropped
so everytime an item is added, iteminslot is instantiated under the slot with the sprite and count. is that also how urs was setup?

image.png
timber tide
#

you can basically do drag and drop without the OnDragging() event. That's purely for visual context for the user for dragging

#

what the interfaces care is where you pressed your mouse, and where you unpressed it

hey guys, am working on a challenge system for my game, and Im having a problem with serializing an array of a custom class.

code: https://pastebin.com/KxvDJTzD

basically, GenTemperature is added to a prefab, and within it I want to define several TemperatureConfigs inside an array, but I can only pass them, but not serialize (screenshot 1).

Im guessing it might have something to do with GenTemperature inheriting from a GeneralBase which is a generic, and maybe Unity doesnt really want to deal with serializing the TConfig or something? I don't think that I missed any [SerializeField] or [Serializable], so I doubt that its the problem...

It's not that any of the individual config fields are at fault either, since its the whole class that is refusing to serialize.

I've tried to outline the structure here (screenshot 2).

image.png image.png
Pastebin
// ------------------------- GenTemperature.cs --------------------...

Pastebin.com is the number one paste tool since 2002. Pastebin is a website where you can store text online for a set period of time.

timber tide
# 
public class GenTemperature : GeneralBase<TemperatureConfig>

The prototype, even though has generic constraints, is still explicitly set as TemperatureConfig so I'm not sure why this wouldn't serialize

swift crag
timber tide
#

oh, problem solved

swift crag
#

Also, it MUST be a unity object if you want to drag it into a serialized field like that

swift crag
#

💥

#

let's try this again!

timber tide
#

is this all in one script?

swift crag
#

okay, ConfigBase is a MonoBehaviour, and GeneralConfigBase is a ConfigBase, and GeneralBase is a MonoBehaviour parameterized by a GeneralConfigBase

#

So the problem is that GenTemperature is a unity object

#

This means that you're going to serialize references to GenTemperature instances.

#

If you want GenTemperature to be "directly" serialized (i.e. not as a reference to something else), it can't be a monobehaviour

#

GeneralBase is a MonoBehaviour, and GenTemperature is a GeneralBase.

rigid robin
swift crag
#

gah, I misunderstood your problem again -- but at least I see the fix now, haha

#

it's TemperatureConfig that you're talking about

#

god, I'm not on the ball tonight

# 
    public abstract class ConfigBase : MonoBehaviour
    {
        public Difficulty difficulty;
    }

it sounds like this should just be a plain old class

#

not one that derives from MonoBehaviour

#

this isn't something you attach to a game object; it's just a bag of data

rigid robin
timber tide
#

yeah would probably better off with a scriptable object

edgy fox
#

is there a way to hide the walls when the camera is on the rear side of them? The white line still shows

image.png
swift crag
rigid robin
swift crag
#

is it part of the model?

edgy fox
#

yeah part of the model

#

it's the bright part that the light under the orange bit catches on

swift crag
#

you can disable the renderer if the angle between the camera and the wall's forward direction is too high

rigid robin
edgy fox
swift crag
#

One caveat.

rigid robin
#

thanks a lot by the way! :D

edgy fox
#

and if I do that will light pass through it?

swift crag
#

If you want to serialize a parent type, then things get a bit more complex

#

say you have Parent with Child1 and Child2

#

If you serialize a List<Parent>, you'll only get the properties in the parent class.

#

This is where [SerializeReference] comes in. It lets you correctly serialize parent types -- it remembers which actual type you have stored

#

However, [SerializeReference] doesn't provide any inspector UI. You have to implement it yourself or use a package that provides one.

timber tide
#

Really I've been fine with single asset SOs for items/abilities. It's fallback for when later on I decide they will become reusable.

rigid robin
swift crag
#

here's an example of a package you can use

swift crag
rigid robin
swift crag
#

if the angle is less than 90, you must be looking at the back side of the wall

edgy fox
swift crag
#

then just disable the renderer

#

It'd be a pretty small amount of work for each wall.

edgy fox
#

true but there will likely be hundreds or thousands of walls in the game scene

#

would that still be impactful?

swift crag

Guys, I have a player which is a ball with like some kind of "armor" around it; the ball moves through players' axis input and a AddForce method, to make it feel more dinamic the ball also adds a torque in the opposite direction (this may cause that when in friction with the floor, it moves a bit faster, that's alrigth, I am counting with that). The issue I have is that the ball moves like, significantly faster when the play window is maximized and I have literally no idea what might be causing that cause I am not using any screen reference for anything, but it is like 3-4 times faster for some reason. Any idea of why is this happening?

then you can move on the orbit stuff, make the one u want to orbit the other..
as you work on it you'll find things you need to work out.. like maybe repositioning the planet so the other one can orbit it properly, or w/e

use keywords like "orbit"

#

youtube has lots of stuff on that mechanic

#

"faux gravity" is another buzzword

# rocky canyon "faux gravity" is another buzzword

Yeah, I can get one planet to orbit the other just fine, it's when I go to get them to switch orbits that I'm not sure. To clarify, I can make planet1 orbit planet2, but can't get planet2 to orbit planet1 on a key click, while making sure the orbit starts from the last position of said planet

if it was jsut the root u could use that ^

edgy fox
#

nah I got a whole family tree

teal viper

Also,you can just transform.parent.parent

north kiln
#

all your .gameObject calls are redundant

edgy fox
#

OMG I thought I always had to call .gameObject before .transform

rocky canyon
#

nah, u only need to use gameObject if you actually want the GameObject

teal viper
#

Transform is a fundamental component, so it's accessible from any other component

edgy fox
#

so I've realized

white apex
edgy fox
#

if I disable an object's renderer, does it disable child renderers?

rocky canyon
#

you would probably need to narrow down your question to something more specific..
like <i have this code so far, and i want to know how to keep the position the planet was last before it begins the new rotation> or something like that.

#

you'll get more answers when people are trying to solve a particular problem, vs brainstorming a system for you

rocky canyon
edgy fox
#

ah ok

rocky canyon
# white apex Right now I have one planet orbiting the other planet

i could think of a way that may work..
having an empty gameobject on the planet thats being orbited.
when you want the other planet to orbit it you could parent it to the empty object
that objects (center/pivot would be in the right position as to just rotate it and the planet would follow..

then w/e position it were at when u parented it (it would retain that offset)

im working on a top down 2d game and when the player walks in water, i want the bottom half of the body to be hidden by the water. how can i achieve this?

rocky canyon

something like this.. 🍀

#

but, could also be done many different ways, since you're new, just play around with it.. find a good method that works for you and try to go with it

#

if it doesn't work out you can always try something else, and just take the knowledge you learned as a bonus

edgy fox
#

can I just have a file with a class without a monobehaviour in it or will the code not be ran? I have a script with only a class with a List but when other scripts try and access wallList it reads as null (Debug.Log(ArrayDict.wallList) returns null)

I copied your hierarchy, and I can't get the outer planet to move when clicking on the gravity field, it just rotates the inner planet

rocky canyon
#

are you sure? screenshot it

white apex
#

(I've been moving planet1 and planet2 around as the parent btw)

rocky canyon
#

u would rotate the Gravity Field..

#

theres no way the PlanetOne wouldn't rotate around PlanetTwo

# 
using UnityEngine;

public class SimpleRotation : MonoBehaviour
{
    public float rotationSpeed = 45f;

    void Update()
    {
        // Rotate the GameObject on its Z-axis
        transform.Rotate(Vector3.forward * rotationSpeed * Time.deltaTime);
    }
}
``` the rotation script im using on Gravity
fresh lintel
rocky canyon
#

the reason I used a child object for the gravity is so the main planet doesn't rotate with it

north kiln
rocky canyon
#

but the gravity would follow around the planet this way, and it should be scaleable.. as if i attached it to another planet..

fresh lintel
rocky canyon
#

mesmerizing lol

white apex
#

It really is haha. Should I restart Unity? I pasted your script in and added it to the gravity, but I don't even have an option to adjust the rotation speed

rocky canyon
#

🤔 really? is the script name the same as the class name?

white apex
#

Ah you know what you right xD

rocky canyon
#

meaning is it named SimpleRotation.cs

north kiln
rocky canyon
#

if not u'll get a compile error and the variable wont be displayed

white apex
#

Yep lmaooo

rocky canyon
#

as long as the gravity gameobject is a child of the planet

image.png
#

and it's position is 0,0,0 (meaning center of the parent)

#

it should all work like the video clip

#

all you gotta do is parent something to the Gravity child.. and it should rotate with it

fresh lintel
white apex
#

Kk, yeah I got planet2 rotating around planet1 now. So my question now is how do I get planet1 to rotate around planet2 on a key press? All I have right now script wise is just your provided rotate script

north kiln
white apex
#

Wait you said parenting earlier, if I wanted planet1 to rotate around planet2, id do this (img) and swap planet1 and 2 around if I wanted planet2 to orbit planet1 right?

image.png
tough lagoon
#

That's the easy way yup

#

Although planets are tricky, and you may end up not parenting them at all and doing it all via code

rocky canyon
white apex
#

Bet, so for the next question then. On a key press (say the space bar for now), how would I change which one rotates, or which one is parented, based on the key press?

rocky canyon
edgy fox
#

how do I make an asset with parents and components

#

explained better: I have a program that instantiates a blank GameObject with a child object and I don't want that object to exist within a scene

#

and I would rather have it be in the assets folder

rocky canyon
#

now if that planet also has the same setup... u could parent the one that was once being orbited to the other planet..

#

and it will just swap roles..

#

the child planet will just start rotating where it is relative to the center of the Root planet

eternal needle
rocky canyon
#

transform.parent = (planets gravity object);
transform.parent = null;

#

^ attach / unattach @white apex thats really all there is to this system..

edgy fox
rocky canyon
#

thats why i like it

edgy fox
#

and the walls run code when they spawn but the Start() function of the walls runs for the first one as well

fresh lintel
edgy fox
#

Essentially I want it as a parameter for a script

#

but I don't want it in the scene itself

north kiln

#

What purpose is this in your game

# edgy fox oh yeah amke a prefab

Also, reference the script you care about on the object instead of GameObject. Ie, If you care about Transform, just reference that.

edgy fox
north kiln
#

Yes

edgy fox
#

I am instantiating it

#

not just referencing a script or anything

rocky canyon
#

he was just pointing it out in case..
for example if it had a script on it that you needed you can just Instantiate using that
it'll save an extra getcomponent call you wouldn't necessarily need

edgy fox
#

oh yeah

#

but no

rocky canyon
# 
GameObject newObject = Instantiate(prefab, Vector3.zero, Quaternion.identity);

bc delegates occur synchronously, if i have a parameter that passes through the delegate, can i modify that parameter? For example, if i have MyDelegate(myParameter) and func1 and func2 are subscribed to that delegate in that order, can func1 modify the myParameter that is passed to func2?

nope

They aren't synchronous then

References are bot pointers, so reassigning a parameter reference isn't gonna affect anything outside the method.

yeah, so i was saying, is there a way to change the parameter that is passed to func2 after func1 occurs

How would that work?

teal viper
#

Or maybe use ref keyword, though I'm not sure of that would work with delegates

teal viper
gaunt ice
#

you can if the type of parameters are reference or pointer by changing its content
but i remeber c# not guarantee func1 must be called before func2

thorn holly
#

i think if func1 is subscribed first then it will be called first right?

teal viper
#

That too. Avoid relying on the order of the delegates.

What's the actual problem? The solution you're wanting to use seems unnecessary.

thorn holly
# ivory bobcat What's the actual problem? The solution you're wanting to use seems unnecessary.

well basically i have the delegate takeDamage(float damageAmount) that does a number of different things, damaging the player, making a message pop up that says the player was damaged, etc. There are some items in the game that reduce the damage the player takes when equiped, so i figured this would be a good way to do it , essentially have all of those items subscribe first, then reduce the damageAmount float before it gets passed to the method that actually reduces the players health

ivory bobcat

add them manually?

thorn holly

# thorn holly add them manually?

Manually?
The same way as you subscribe them now. But instead add them to a list(register them for evaluation if that sounds cooler).

And in general

It would be easy to, for example, add additional conditions or modifiers into the calculation.

You probably have the mask set such that it only includes one layer.

these are two different layers I would be asking to allow IsGrounded to jump on both a object and the ground. I dont know how these can be used in the same raycast. your right, i only have the groundLayer in there

These are 2 different layermasks, not layers

don't call it groundLayer. Bad variable name. This would be your groundCheckLayerMask or something along those lines

should i be concerned about overusing delegates? Like will it cause performance issues or something?

#

in the sense of multicast delegates

wintry quarry
thorn holly
#

What are orphaned subscriptions?

#

and what do i do about the garbage?

#

@wintry quarry ?

teal viper
#

I assume they mean a destroyed object still being subscribed to a delegate/event is what they mean by orphaned subscription.
As for the garbage, you live with it.😎

thorn holly
#

does garbage affect performance?

teal viper
#

In extreme cases, yes

thorn holly
#

rut row

teal viper
#

What they mean by garbage is simply memory allocation. If you don't handle memory allocations correctly, you would be allocating new memory, while making the GC(garbage collector) dispose of the old allocated memory that is not used anymore. Allocating/disposing of memory can be performance heavy if there is a lot of it every frame.

thorn holly
#

oh i dont have a lot every frame

#

i just have a lot of delegates

#

but on different frames

#

so thats okay right?

teal viper
#

Probably. Hard to say without seeing your project. Anyways, if performance is a concern,you should use the profiler to pinpoint the cause.

thorn holly
#

alr

#

well im just making a small battle system and im using a lot of delegates for it to do small things. For example, at one point theres one of three options you have to select, so i made a delegate that triggers at the start of that to make the three options have a red highlight when you hover over then, and then i have a delegate after you select something that turns off that option

I don't see any issue here. My suspicion is you're either not seeing momentum but you think you are for some reason, or your script changes haven't been picked up for whatever reason, or there's something else going on entirely that isn't visible in these screenshots

If there an obvious reason why two different vector3s with the same x y z would produce different hashs?

#

This is Via .GetHashCode()

What would be the best way to do this?

I have tried also by checking x,y,z converted as ints as well.

teal viper
eternal needle
# white apex What would be the best way to do this?

i guess it depends on the gameplay, parenting might work in your case but in complex cases maybe not. I would just have the objects store a list of objects which they affect, then remove any parenting stuff

tender wren
# 
int sum = ((int) v.x + (int) v.y + (int) v.z);
sum.GetHashCode();

Example of what I tried, also the output for a vector float shows the same, but is everything after the 0 obfuscated by unity? like could 1.0 actually be 1.00001 or something

teal viper
#

casting to int discards the decimal part

#

So, if sum hash code is the same, but vector isn't, then the decimal part of the 2 vectors is not the same.

tender wren
#

Example of edges built with vectors collected:

image.png image.png image.png
#

I slid one over for a better view.

teal viper
#

I really feel like you should avoid hashcodes with Vectors/floating point numbers and specifically in your case.

tender wren
#

I am essentially trying to determine if the edge of different meshs are the same reguardless of how many edges are in the list of edges.

teal viper
#

You can do simple Vector equality or get the distance between them

white apex
#

!code

eternal falconBOT
tender wren
#

I think it has something to do with the edge itself as with the unity default cube when looking at all verts there are only 8 unique, but with my edges they are not.

Vector3 v = new(1.0f, 1.0f, 1.0f);
Vector3 y = new(1.0f, 1.0f, 1.0f);

if (v.equals(y)){
//do something
}

Something like this?

white apex
# 
using UnityEngine;

public class PlanetSwapHandeler : MonoBehaviour
{
    public KeyCode switchKey = KeyCode.Space;

    public GameObject CenterPlanet;
    public Transform PlanetOne; 
    public Transform PlanetTwo;
    private bool isSwitched = false;

    public GameObject CenterPlanet2;

    void Update()
    {
        // Check if the switch key is pressed
        if (Input.GetKeyDown(switchKey))
        {
            SwitchHierarchy();
        }
    }

    void SwitchHierarchy()
    {
        if (!isSwitched)
        {
            CenterPlanet.transform.SetParent(PlanetTwo);
            CenterPlanet2.transform.SetParent(PlanetOne);
        }
        else
        {
            CenterPlanet.transform.SetParent(PlanetOne);
            CenterPlanet2.transform.SetParent(PlanetTwo);
        }

        isSwitched = !isSwitched; // Toggle the switch state
    }
}

Does this look right?

tender wren
#

When iterating through the edges it will only take the direction into account, but not the mirror or reverse of the edge.

teal viper
#

Especially with geometry, you can be almost entirely sure that you'll have huge floating point deviations, so even if 2 points were originally the same, the wouldn't be in the final mesh.

teal viper
tender wren
#

ok I think I figured part of it out, alteast im not getting random hashes every time I can the same edge now its the same, but some of them are producing 0, which I assume is because they are local verts are 0

# 
    public int HashEdges(List<Edges> faceedges)
    {
        int hash = 0;
        foreach (Edges e in faceedges)
        {
            hash += e.pointOne.GetHashCode() + e.pointTwo.GetHashCode();
        }

        return hash;
    }

If the mesh is four verts are y=0 though it seems to be generating the same hashes for negative and positive values.

teal viper
#

I don't think adding up hashcodes is a good idea

#

You're gonna end up with a lot of false positives

tender wren
#

You think this would be easier if I made my own vector3 class that uses int's and converts them to floats when I need to draw them?

#

All edges are on a 4x4 grid

#

so I shouldnt ever need a float

gaunt ice
#

hash table basic:
the basic idea is to separate some elements by grouping them (so why you can see some people call it bucket) eg
1 2 3 4 5 and we have bucket 1 2 3, you can group them by
bucket 1: 1 4
bucket 2: 2 5
bucket 3: 3
by grouping them with hash function val%number of buckets= val%5, (ofc the most efficient way of grouping them is to have 5 buckets so that each bucket only contain 1 element)
ok now dealing with floating point value, since 1 and 1.000001 are considered to be the same (with threshold<0.000001 and 1.000001 and 1.000002 are the same and so on, by induction hash code for all floating points are all the same......
hash table is not solution for all lookup stuff, please learn before you use it

teal viper
tender wren
#

It should work without having to use ints though, I am just not sure why they don't equal the same thing. It has something to do with my Edge class

        Vector3 v = new(1.0f, 1.0f, 1.0f);
        Vector3 y = new(1.0f, 1.0f, 1.0f);
        Edges x = new Edges(v, y);
        Edges t = new Edges(v, y);

print(v.GetHashCode() == y.GetHashCode()); <<<<This is true.
print(x.GetHashCode() == t.GetHashCode()); <<<<This is false.
gaunt ice
#

you can have 16 different vertices and the edge just store the index of vertex
you can quickly determine if one or more vertices overlapped

if I want to set a variable from of a class from another should I make that variable public or is it better practice to create a function instead called SetVariable(float Vector2){} instead?

But generally I think it's just a floating point error when you copy the vectors around.

    public Vector3 pointTwo;

        pointOne = pOne;
        pointTwo = pTwo;

    }
    public override string ToString()
    {
        return "{ " + pointOne.ToString() + " : " + pointTwo.ToString() + " }";
    }

    public bool CompareEdge(Edges edge)
    {
        if (((edge.pointOne == this.pointOne) && (edge.pointTwo == this.pointTwo)) || ((edge.pointTwo == this.pointOne) && (edge.pointOne == this.pointTwo)))
        {
            return true;
        } else
        {
            return false;
        }
    }

    public override int GetHashCode()
    {
        return this.pointOne.GetHashCode() + this.pointTwo.GetHashCode();
    }
}
#

Previously the override of gethashcode was not there

#

The override changed nothing.

teal viper
#

Yep, probably a floating point error, but also the way you add up hash codes isn't gonna result in anything good.

tender wren
#

yeah I just wanted to see if I wrote over the hash function if the previous set of code would be true. It was, but still didnt resolve my issue.

i have a planetary gravity system where i have a vector for the gravity that is being set to the planet's world position that the player is currently on, the player becomes a child of the planet that it's on.

public void SetGravityVector(Vector3 newGravityVector) // setting the newGravityVector to the planet's transfrom.position
{
     gravityVector = newGravityVector.normalized;
}

i encountered a problem where when i set the gravity vector, it barely moves in world space (i am drawing a gizmo) the first image is the gravity vector at (0, 0, 0) and the second one is at (-641, 632, -1811).
you can see that it barely even moved, also this is just really zoomed in. why is the vector not being set correctly? could it be that the player is a child of the planet or is it that the planets' scales are a thousand units?

how to check if an object inherits from something?

object obj = EditorUtility.InstanceIDToObject(id);
if (obj inherits MonoBehavior) {
  DoThis();
}
else {
 DoThisInstead();
}

(obj.GetType().IsAssignableFrom(typeof(MonoBehaviour))) this doesn't work. It's always returned false regardless if it is MonoBehavior or not.

rare basin
#

why do you need to check that

#

is that inehrited class a MonoBehaviour?

#

you can just do TryGetComponent

#

or GetComponent and null check

#

public class Dog : Animal

#

then if oyu have in other class

#

public Dog myDog

lean basin
#

Debugging purpose.
I tried to pass MonoBehavior and not. But it returned false regardless.

rare basin
#

you can check if myDog.GetComponent<Animal>() != null

lean basin
rare basin
#

you are making your custom inspecor?

lean basin
# rare basin you are making your custom inspecor?

ehm no. I had a List<int> with a list of item's InstanceID. I want to show what Component those InstanceID belong to. But sometimes they are just random integer, not an InstanceID that belong to anything.
I wanted to tell the difference between the two.

rare basin
#

why are you storing instanceID's

#

instead of just game objects

lean basin
#

because it's not always a gameobject

rare basin
#

what is it then sometimes

lean basin
#

just an integer.

rare basin
#

an integer cannot inherit anythnig

#

so im confused what arey ou talking about

hexed terrace
#

If there's no object, why is it being stored?

lean basin
#

you can read my question again.
It's a List of integer.

But some of these integer is belong to a component. Some are not

rare basin
#

that makes no sense

lean basin
#

I'm using EditorUtility.InstanceIDToObject(id); to check if it does belong to a component.

rare basin
#

what do you mean by integer belonging to a component

lean basin
#

OHH.. the integer is InstanceID that belongs to a component

rare basin
#

sure but why are you storing the instanceID instead of the object

lean basin
rare basin
#

then instances of what do you have then?

hexed terrace
#

Object != just GameObject

#

How is the list created?
If there's just an int .. why is it being stored at all ?

rare basin
#

yea i dont get it aswell

#

i guess he is storing objects by instance ids

#

then he wants to check if that objects inherits from any particular class

lean basin
#

No i don't want to store objects. I want to store key, identifier, index, or whatever you call.

rare basin
#

but index of what

#

instanceID is a ID of INSTANCE

lean basin
#

It doesn't matter if it's an object or not in the game logic.

But I'm writing a debugging tool that try to figure out if those integers in the list has any relation to a component. Because some of those integer is Component's InstanceID.
but that doesn't mean everything is InstanceID.

rare basin
#

so you have a List of ints

#

and some of the ints are instanceID

#

and some arent?

lean basin
#

correct

rare basin
#

that doesn't seem liek a correct approach

#

how do you populate the list

#

and why do you add incorrect ints in there

#

so what are the other ints

#

that arent instanceID's

lean basin
#

oops wrong way to post the code.

#

ehhmm its just an ordinary integer that doesn't mean anything

rare basin
#

so why do you add it to the list then

lean basin
#

because it does something!!
hmm my bad. it does mean something. but it's not instance ID

rare basin
#

then why is it inside the list of instanceID's

lean basin
#

ITS NOT A LIST OF INSTANCE ID

#

its just a list of int

rare basin
#

you have a list of mixed things

#

just split it
