Your grass condition is impossible. You're running that code if WorldTiles does not contain that point, but then you check if it does. It cannot both contain and not contain that point

minor roost
#

oh

#

how do ichange it

polar acorn

#

so how do i make it possible

polar acorn
#

You need to think about what conditions need to be true to spawn a grass tile

#

And don't make impossible conditions

queen adder
#

the argument i put into the function is non zero, however after the equation motion * time.deltatime, it returns 0,0,0.

why?

#

no but ill do that

#

hmmm it doesnt return 0,0,0 anymore

#

just extremely small numbers

#

i'll up the amplitude, see if i get results

#

my code works now! thank you all for the help :>

Everytime I run my build script for dedicated server it changes the settings in the build settings to dedicated server and I have to switch it back to client, any way to no have that happen?

How does one fix camera stuttering/jittering?

cosmic dagger
hidden bone
#

the camera sets its position to the player's position in Update()

slender bridge
hidden bone
#

yes the player has a rigidbody

slender bridge
#

track the player in late update and see if it helps

#

it would probably help to post your code for the camera movement and how its situated in your hierarchy.

hidden bone
#

it seems slightly worse, although i may have implemented it incorrectly

# 
        transform.position = cameraPosition.position;``` this is the camera follow script
# 
    {
        mouseX = Input.GetAxisRaw("Mouse X");
        mouseY = Input.GetAxisRaw("Mouse Y");
         
        yRotation += mouseX * sensX * multiplier;
        xRotation -= mouseY * sensY * multiplier;

        xRotation = Mathf.Clamp(xRotation, -90f, 90f);

        camHolder.transform.rotation = Quaternion.Euler(xRotation, yRotation, 0);
        orientation.transform.rotation = Quaternion.Euler(0, yRotation, 0);
        transform.rotation = Quaternion.Euler(0, yRotation, 0);
        
    }``` and this is the Look script
#

the camera and player are separated

slender bridge
#

im assumming cameraPosition is a reference to your player object ?

hidden bone
#

yes

slender nymph
cosmic dagger
hidden bone
#

i sampled this from some random tutorial a while ago

hidden bone
slender nymph
#

obligatory "use cinemachine"

#

but if you must do your own camera controls for whatever reason, you typically want to move your camera in LateUpdate if it is following something that moves in Update

hidden bone
#

putting the follow script in LateUpdate exarcerbates the issue

cosmic dagger
slender nymph

#

alright thank you both, i'll use cinemachine

A shortcut is placing an empty child GameObject on the target and tracking that instead . . .

how to do a responsive movement like in valorant using add force. Any forcemode I use doesnt seem to make it feel like what it's supposed to (move when a key is held, and stop immediately after not pressing)```cs

    if(!IsGrounded) rb.AddForce(new Vector3(Input.GetAxisRaw("Horizontal"), 0 , Input.GetAxisRaw("Vertical")) * speed, forceMode); // in FixedUpdate

sterile radish
slender nymph
#

what is its value?

queen adder
sterile radish
slender nymph
#

are you sure

sterile radish
#

yes

queen adder
#

problem with this one is that, you wont move at all when speed is low enough (on majority of forcemode)

slender nymph
# sterile radish yes

then you need to be specific about what you are expecting to happen versus what is actually happening

sterile radish
slender nymph
#

show the rest of the code and the inspector for the object

sterile radish
#

do you want the full script?

slender nymph
#

yes

sterile radish
#

okay

slender nymph
#

okay and just to confirm, you are intentionally setting gravityScale to 0 only after your airTimeCounter is greater than airTime?

sterile radish
#

yes

#

well whenever my counter is equal or greator to than my airTime

slender nymph
#

so you want more gravity for the duration of your airTimeCounter? 🤔

sterile radish
#

wdym

slender nymph
#

i mean that gravity scale being 0 is less gravity. so only after your airTimeCounter has reached the value of airTime do you reduce gravity

sterile radish
#

yeah thats right

solemn fractal
slender nymph
#

because right now you have normal (or what i assume is normal) gravity for the duration of the airTime which means you fall faster for that duration

sterile radish
sterile radish
slender nymph
#

sure but you never go to 0 gravity until after you pass that airTime threshold

sterile radish
#

oh yeah

#

so should i set my gravity to 0 during the duration of my counter and only set it back to it's og amount when it reaches my airTime value?

slender nymph
#

yes

sterile radish
# slender nymph yes

i still have to tweak some stuff but im glad i found the problem thank you!! :)

Could anyone help me with smoothing on a slider? 😅
This implementation is not working at all. I don't really know what I'm doing in Mathf.SmoothDamp -

public class ExperienceView : MonoBehaviour
    {
        [SerializeField] private Slider _experienceSlider;

        private float _currentVelocity;
        private int? _xpUpdateAmount;

        private void OnEnable()
        {
            ExperienceService.Instance.OnXPGained += UpdateXPSlider;
        }

        private void OnDisable()
        {
            ExperienceService.Instance.OnXPGained -= UpdateXPSlider;
        }

        private void Update()
        {
            HandlePotentialXPUpdate();
        }

        private void HandlePotentialXPUpdate()
        {
            if (_xpUpdateAmount is null) return;

            // !! THIS PART !! 

            _experienceSlider.value = Mathf.SmoothDamp
            (
                _experienceSlider.value,
                (float)_xpUpdateAmount,
                ref _currentVelocity,
                10f
            );

            if ((int)_experienceSlider.value == _xpUpdateAmount) _xpUpdateAmount = null;
        }

        private void UpdateXPSlider(int newXPAmount)
        {
            _xpUpdateAmount = newXPAmount;
        }

that makes it nullable

#

also they are using unity's Slider object

queen adder
#

heres my code,

slender nymph
#

don't multiply your mouse input by deltaTime

queen adder
#

i am trying to make the sway variable give the camera a little sway when it moves on the x axis.

#

however,

#

inside the camsway function

#

when i lerp the sway variable to 0, it gives me a very quick climb down to 0

#

resulting in the camera shaking

queen adder
#

unless youre not talking to me

slender nymph
#

yes, don't do that

queen adder
#

then whoopsies

#

what?

#

should i just

#

take it off entirely

slender nymph
#

don't multiply your mouse input by deltaTime

#

yes, because you should not be multiplying your mouse input by delta time.

queen adder
#

well

#

if i do that the sensitivity goes sky high

slender nymph
#

reduce your sensitivity by a factor of 100

queen adder
#

ok

spiral narwhal
slender nymph
#

you currently have smoothdamp set to take 10 seconds to go from the current value to the end value. but you're also just assigning the current value to the end value every time you change the value

queen adder
#

anyways uhh could i have help with my sway problem

slender nymph
#

what debugging steps have you done

spiral narwhal
slender nymph
#

if that is the intention then why are you using SmoothDamp

spiral narwhal
#

too smoothly transition from one value in the slider to another

slender nymph
#

because _xpUpdateAmount is already equal to _experienceSlider.value

#

ah wait, i think i misread what you are subscribing to

spiral narwhal
#

Mm, perhaps I've got some kind of misconception.
What I think I'm doing is this:

  1. I start with the current value of the slider
  2. I intend to increase it until _xpUpdateAmount is reached
  3. that intermediate step is what I intend to assign to _experienceSlider.value
slender nymph
#

you also need to describe what exactly isn't working. because so far all you've said is that "This implementation is not working at all" which doesn't really say what is wrong

spiral narwhal
#

That's fair, sorry!
I've changed 10f to 1f (one second?) and it incorrectly does this: it slowly updates the slider value, but either it stops too early, or it doesn't use the correct target value (for example 40% is more like 10%)

slender nymph
#

have you printed out the values of the variables you are using or used breakpoints to inspect them to see what is going on?

spiral narwhal
#

No, but I feel like SmoothDamp isn't really what I'm looking for. I'll try a simple Lerp.

queen adder
#

do you manually do gravity if you want to use character controller?

slender nymph
#

if you want to jump, yes. if you don't care about jumping then you can use SimpleMove which applies gravity but ignores any movement along the Y axis

buoyant knot
#

there are lots of times where you want to make sure gravity is just right. like no gravity when standing on a slope, or higher gravity when falling then jumping up

I am trying to instantiate an object facing the player with a rotation that is lined up. It spawns in the right place but for the Quaternion it won't line to the player's rotation. I've tried the player's rotation which spawns it at an opposite rotation and the Quaternion Inverse which also didn't work.

is uv the image texture?

teal viper
#

Uv is an array of vectors per vertex that determine what point in the texture should be sampled at/around each vertex.

#

Uv mapping if you heard about it.

somber herald
#

oh so like uv unwrapping

#

turns that into a uv map right?

Yes

The layermask that you pass into the raycast is just the layers you want it to interact with
You DON'T want it to interact with the player, and probably not default or other things like that

dawn rampart
summer stump
#

Also, you are starting the raycast from the center of the object and going down .1f

dawn rampart
summer stump
#

Ok good. The issue is probably that the raycast simply doesn't reach

#

You can make an empty object and make it a child of the player, then move it to the feet. Use that as the origin of the raycast

Hi all i need some help with 2 problems i got.

  1. I have some "pets" in my game. They are on their own scene and they basically just walk around in an fenced off area. I want them each to drop say a 💩 (turd) every hour or so (but not all at once).
    How can i make them drop that turd that will be a button in the game so when the player clicks on it they will get a small reward of coins, gems or pet food. Im stuck y'all. I tried google with no luck.

  2. In my main game where the player does their main gameplay which is kill monsters. I have a panel that pops up when the player levels up to tell them they have leveled up and to give them a rewards. Thats all working great. But i want to gameplay in the background to pause/freeze while they are in the level up popup. I have tried setting timescale to 0 while the panel is open and back to 1 when the panel closes but the background gameplay still doesnt pause. Also i tried making a public enum GameState. I added move and pause to it. Then in my start i i said currentState = GameState.move;
    Then when the panel opens i made the GameState to pause.
    But that also doesnt seem to pause the game.
    The only time it pauses is if i click on the GameState button on my script in the inspector. Like only if i click that button to choose what state i want. But it doesnt matter what state i choose the game still keeps running in the background.

I ended up with this:

#

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

public class RandomMovement : MonoBehaviour
{
public float speed = 5f;
public float changeDirectionInterval = 2f;

private float nextDirectionChangeTime;
private Vector3 targetDirection;

void Start()
{
    ChangeDirection();
}

void Update()
{
    // Move the object in the current direction
    transform.Translate(targetDirection * speed * Time.deltaTime);

    // Check if it's time to change direction
    if (Time.time >= nextDirectionChangeTime)
    {
        ChangeDirection();
    }
}

void ChangeDirection()
{
    // Generate a random direction (side-to-side movement)
    float randomX = Random.Range(-1f, 1f);
    Vector2.x = Vector2.x + randomX;
}

}

#

but there is an error:

#

Assets\Scripts\SlimeMovement.cs(34,21): error CS0120: An object reference is required for the non-static field, method, or property 'Vector2.x'

summer stump
shrewd arrow
#

It is supposed to change the x by -1 to 1 based on a random variable

#

I meant to use Vector2 to do that, I am very new

summer stump
#

Well Vector2 is a type.
So you would make a variable that IS a vector2:

Vector2 newDirection;

newDirection = new Vector2(randomX, 0);
#

Something like that

#

ok, thx, ill try that

Normally methods will run until they complete, and the computer can't do anything else until it DOES complete

i feel like i might be being a major dum dum, but i cant find out why the camera is always defaulting to being turned at a 0,0,0 rotation whenever i start the game

#

even if i change it itll switch it to 0,0,0

#

will locking the cursor cause that?

#

oh i see, its from line 42 updating its rotation to it nvm

ivory bobcat
# acoustic arch even if i change it itll switch it to 0,0,0

To retain initial inspector changes, you could do something like..cs void Start() { //locking the cursor to not be visible Cursor.lockState = CursorLockMode.Locked; var initAngle = transform.localEulerAngles; mouseX = initAngle.x; mouseY = initAngle.y; }

# chilly vigil help how can i fix this

In ChangeCircle, line 35, you wrote Input.something but you are using the new input system, and that is not compatible under your current settings

If you go to something like Edit > Player there is a "current input mode" or something like that where you can select "both"

hey im coding a simple turret shooting 3d game. Im currently having trouble with enemy collider detection so that the application quits when colliding with the player. This is the function im using in the enemy script.

void OnCollisionEnter(Collision collision)
{
    // Check if the collision is with the player (tagged "Player")
    if (collision.gameObject.CompareTag("Player"))
    {
        // Quit the application to stop the game
        Application.Quit();
    }
}

Currently both player and enemy have colliders (enemy has rigidbody too so i can freeze its rotation as I dont want it to fall over when moving towards the player). The player is tagged appropriately. Not sure whats wrong, ive added a debug as the first thing in the collisionenter function but it didnt even hit that. Ping me if you can help :D

summer stump
#

I assume the Enemy?

north scroll
#

yep

summer stump
#

Application.Quit doesn't work in the Editor by the way, but it not showing the debug means the issue is something else

yea the only other thing i tried was increasing the collider size of the enemy every so slightly outside of the mesh/capsule itself, although im sure that wasnt the problem. And ok, i will take a look ty

you should def select the animator on the object while you inspect that animator event

so you can link the method properly
also make sure there aren't any transition issues like leaving clip early

#

It does format correctly, and no it doesn't read it as comments, it grays out the part that doesn't compile in that setup

and the player doesn't play the game in the Unity editor so Application.Quit just closes the game

this feels a little slow
I feel a delay when I touch the ground, it takes a little while for isGrounded to be true

worldly jolt
#

i dont know if this is the issue but creating two new vector2s every single frame is probably slowing your game down a lot

eternal needle
worldly jolt
#

im not sure if you need to say new Vector2 or if you can just go body.velocity.x, speed rather than new Vector2(body.velocity.x, speed

young warren
#

OnCollisionEnter2D runs on a fixed time step because it's physics based. that might be why

not sure how much of a delay you feel though

how can I edit a pre existing prefab? I created an enemy prefab and then continued working on it after trying to implement a score TextmeshproUGUI. Only problem is when I try to drag the text object here, it doesnt let me add it

image.png
languid spire
#

you cannot add scene objects to prefabs

fickle plume
rare basin
#

althought the structure looks bad, Enemy shouldn't have references to your UI score text

north scroll
rare basin
#

you instantiate the Enemy, and then assign the referecens via code

north scroll
#

that's not really helpful. I get that as programmers we're all for "critical thinking", but that "via code" is just a useless statement.

I thought that if I was able to publicize variables, I could just drag and drop them in the unity inspector, but it seems I can't do that with prefabs. Imma just look for a way to reference the textmeshgui through start() i guess

rare basin
#

yes you can

#

you just can't drag&drop scene objects to prefabs

#

and as I said, you shouldn't have reference to your UI score text inside Enemy script

#

instead you should have some kind of UI manager, and when the enemy dies, access that UI manager in your enemy Die() function, and change the text

ruby python
#

For scores and the like, maybe look at using a Singleton?

rare basin
#

you should make UIManager (singleton) or ScoreManager (singleton)

#

and when enemy dies access that singleton and increase score, change text, call an event whatever

north scroll
#

new to this, never heard of singleton before

rare basin

#

They're incredibly useful.

SetParticles does not work via script. Did you have similar problems to set particles through script?
I have checked, particle array passes to SetParticles correctly

                    _rippleParticleSystems.Add(ripplePSInstance);
                    ripplePSInstance.transform.position = Vector3.zero;
                    ripplePSInstance.SetParticles(_ripples, rippleCount);
                    ripplePSInstance.Stop();

ah wait, i see the issue. you're creating brand new instances of those objects for each iteration of your loop

i create a new instances for a gameobject called Machine and the machine is supposed to add +1 to the money in the GameManager script

machine is not a gameobject

and you're adding to the money field of Player not gamemanager

Player is also not a GameObject or even a component

so dont expect the best clean code ever

slender nymph
# mellow flint im still new to programming btw

then you should go through some beginner courses to learn what you are doing. and learn how to reference other objects.
because you're still just creating completely separate instances of the Player object that have nothing at all to do with your GameManager or even each other

#

on top of that you're still creating a new Player instance every single frame inside of Update for some unknowable reason

no on collision as you see the object keeps on going in the opposite collision direction

oh. sorry!

slender nymph

because you need drag to slow an object down over time

its not my code, it belongs to a friend. I cant try it out and see. UnityChanOops I thought it was because he was using moveposition instead of rb.velocity. thanks for the help!

ivory bobcat
#

Tell your friend to try it out

patent compass
#

No problem. But my question still stands, is moveposition reccomended over velocity? I thought it causes issues with collisions

ivory bobcat
#

The docs suggest move position for kinematic rigid bodies

patent compass
#

So i was right. he should use velocity since its dynamic

Hi. I wrote a script: "NoteRead", which allows you to read notes. This script takes the text from another script: "Note". With just the text, everything was fine, and everything worked fine. When I decided to add another font (notes for a change), when I open the sheet, I get an error. I tried to inherit the script: "NoteRead" from the script "Note", but nothing helped. Line: 29
Mistake: ArgumentException: GetComponent requires that the requested component 'FontData' derives from MonoBehaviour or Component or is an interface.

is FontData a scriptable object, non-monobehaviour class or what is it

I'm assuming the stuff on the left hand side of the assignment operation is simply made up and thus the line makes very little sense.

rare basin
#

this is a Text component

#

nothing related to your FontData

whatever FontData is

slender nymph
rare basin
#

and Text component is deprecated

is FontData something you created yourself?

yes you can

of course you can

you can do much more things than in deprecated Text component

so you can access all the Text fields

but you really shouldn't use Text, use TextMeshPro instead

hello
im having a problem with classes.

basically i have a class called "HomeData" inside of another class called "HomeManager".

this i the "HomeData" class:

[Serializable]
    public class HomeData
    {
        public string HomeSize = "Default";
        public string Floor = "Default";
        public string Roof = "Default";
        public string WallTexture = "Default";
    }

the problem is when i do "new HomeData()" it just = "HomeManager+HomeData" for some reason but i want it to be all the data inside of home data so like (HomeSize = Default, Floor = Default) and so on

ivory bobcat
lucid jetty
#

only the collider returns

#

the object is gone but the collider comes back

ivory bobcat
#

Not certain how you're respawning but if it's a reload of the scene, everything should return to normal.

#

Why does it come back? You'll need to tell us. The code provided simply destroys whatever triggered it.

its a function from the LeenTween library

You probably aren't wanting to destroy the object. This object is also responsible for returning your player to a recent position

#

Looks like a feature request with conflicts of your current system which folks won't normally write/code. But an optional simple solution would be to disable the collider component.

lucid jetty
ivory bobcat
#

I'm not certain since it would seem you're referencing a list of game objects (supposedly check points) as well

It would depend on your setup

You've got a lot of random stuff in your spawn manager.. Maybe have a script on the check points and simply let this spawn manager be responsible for respawning - decouple some of the random code. //Spawn Manager Player (Game Object) Respawn Position (Vector 3) Previous Previous Check Point (Check Point script)`````` //Check Point Spawn Manager (Spawn Manager Script) On Trigger Enter Respawn Position equal to this position Respawn Enable Previous Check Point Respawn Previous Check Point equal to this Check Point Disable this component (the Check Point Script)Assuming you're allowing backtracking to previous checkpoints. Stuff done in trigger is an implied interaction on the Spawn Manager reference.

# kindred comet How do I loop through a json

You are gonna have to give more context to what you are trying to do with json. In unity, most people convert a json file to c# class using unitys built in Json utility class or newtonsoft.

kindred comet

create the class, dont use the dictionary

Creating a class will be cleaner and easier to access the key names than a dictionary.

kindred comet

So like a dictionary?

gaunt ice

so you have an array of JsonLoader class, and the field name is peridodictable

kindred comet
#

the issue is idk what JsonLoader is exactly all i know is it has all my variables i need

#

and i don't know how to use that information to convert my json into a usable dictionary / array / whatever

btw you can rename the class to other eg Atom, more easy to read

alr

where do i go from here tho

I wonder how you get the json if you dont know json...

timber tide
#

can just treat it as text and make your own parser if you want

note that you aren't going to be writing and reading json yourself

you're just going to tell JsonUtility "please turn this object into JSON" or "please turn this JSON into an object"

use a debugger

#

put a breakpoint after changing the sprite

#

and see if it has the correct sprite

#

if yes, then you are overriding it somewhere else

im making a vr game and i want that whenever the button is pressed, the door opens. how?

rare basin
#

that's such a generic question

#

you can handle it in many ways

cerulean kestrel
#

i kinda just started lol

rare basin
#

open the door via animation, move it by code, whatever you want

#

make interaction system for the buttons

#

so you can interact with it

#

and link the Interact() of this particular button to open the door

cerulean kestrel
#

i have never coded once in my life

#

THATS the problem

Hi all, okay, so I'm trying to hide objects in a hierarchy by firing a ray from the camera (Camera is always a fixed view looking at the player character, so anything in between the two should turn off)

The issue I'm having is turning the objects back on, the way I've got it at the moment, the object that should be 'inactive' is flashing on and off, and I'm not sure how to fix it. Could anyone take a look please and point me in the right direction?

RaycastHit hit;
        if (Physics.Raycast(transform.position, transform.TransformDirection(Vector3.forward), out hit, Mathf.Infinity, objectToHideLayerMask))
        {
            Debug.Log("Hit Something that should be hidden now");

            GameObject objectHit = hit.transform.gameObject;
            objectToHide = objectHit.transform.parent.gameObject;
            objectToHide.SetActive(false);
        }
        else
        {
            if (objectToHide != null)
            {
                objectToHide.SetActive(true);
                objectToHide = null;
            }
        }
rare basin
#

you cannot detect disabled colliders

#

with raycasts

ruby python
#

Ah crap, of course you can't. 😕

rare basin
#

you might want to for example only disable the renderer

#

but keep the collider on (as trigger so you cant collide with it)

#

so the object won't be visible

ruby python
#

tbh I did think that, but it would be massively inefficiant (the hierarchy is floors of a building with a crapton of items in each floor.

rare basin
#

why would that be inefficiant

#

it doesn't make any difference if you disable the entire object or just the renderer

ruby python
#

Because I would have to disable/enable every single mesh renderer.

rare basin
#

the object is still phyiscally there

rare basin
#

so instead, just disable/enable the renderers

#

objectToHide.GetComponent<MeshRenderer>().enabled = false;

#

assuming the renderer is attached to objectToHide

ruby python
#

Yeah with one 'operation', disabling the renderers for every object would be different.

rare basin
#

no

ruby python
#

There's a renderer for the actual buildings floor. But the floors are populated with lots of other seperate objects (chairs/lamps/furniture etc etc).

#

Each with their own renderer.

rare basin
#

so what is the issue

#

i still dont understand

#

is objectToHide the prop?

ruby python
#

objectToHide is to hide the floor. The furniture objects are children of the floor object.

summer stump
#

When you disable the parent object, it goes through and disables each child already. This would be more efficient since it only deals with one component on each object

swift crag
#

the colliders are lost, though, and that's an issue

#

I would suggest redesigning this a little.

rare basin
#

you should have a Floor class

#

that stores all the props

#

and just disable the props

#

List<Prop> floorProps

#

then just iterate over them and do whatever you need on disable/enable

swift crag
#

Create a collider that encompasses the region. Use that to decide whether or not you want to activate the floor. The collider should not be part of the floor itself.

#

So it'd look like this

#
  • Floor
    • Occlusion Collider <-- raycast against this
    • Contents
#

turn off Contents as needed

#

You could write a little editor script to grow the collider to fit everything on the floor, or just hand-author it

rare basin
#

yea your Floor should be preferably just an empty game object with a Floor class maybe with an additonal UnityEvents OnTurnedOn, OnTurnedOff, list of props etc so you have much more controll, and content/collider sepearte childs

swift crag
#

This assumes you want to disable entire floors at a time.

I’ve got a small problem, I’m trying to make it so when the player walks into a “pod” the player movement cancels and the camera switches to the pod. Those both work but I made it so you could move the pod after and the player gets left behind.

My plan is to make the player speed a variable I can match to the pod’s when canMove= false, but I can’t figure that out

languid spire
#

why not just parent the player to the pod?

swift crag
#

You shouldn't try to make the player's movement exactly match the vehicle's, yes.

#

that'd be a never-ending treadmill of problems

rare basin
swift crag
#

what if the player gets stuck on something and the vehicle doesn't, or vice-versa?

#

it sounds like you want the player to enter the vehicle and then pilot the vehicle around

ruby python
woeful hedge
rare basin
#

that is not what i told you to do

woeful hedge
#

then how?

#

uhh where is the sprite

#

yup its not

rare basin
#

AFTER

#

not BEFORE

woeful hedge
#

brain issue

#

sorry

#

than I'll make breakpoint at yield

#

ok the code works so the sprite got changed and returned to idle sprite after 1 frame

#

so who changed damn sprite?

#

the animator?

#

I used this first time, so there are no hidden codes that changes sprites
(at least I wrote)

#

so

  • I made Animator speed to 0.0f (to disable IDLE animations, seems no methods to stop the Animator)
  • and Changed to Other Sprite
  • and It changed to IDLE animation Sprite after 1 frame
  • there is no additional my Components written by me except this and there is no code that changes sprite except this line.
#

but why??

#

does anyone knows how to solve this?

swift crag
#

If the animator writes to a property in any of its states, it will constantly write to that property

#

One option is to set the property in LateUpdate

#

Update runs before animators. LateUpdate runs after.

#

Setting the layer weight to zero might work? I do not remember.

#

(but you can't set the weight of the default layer)

woeful hedge
#

will disable animator should work?

#

hmm anyways thanks

swift crag
#

Yes, disabling the animator would stop it from doing anything.

proven lark
#

I just started unity and this is my first time coding and i was wondering what the bracets mean in code

swift crag
#

Braces group multiple statements into a single block statement.

languid spire
# proven lark

they define something called Scope. That is the period of the code that the varaibles defined with in are alive

swift crag
#

A statement is, intuitively, a single line of code.

#

(that is not the technical definition, but good enough for the moment)

proven lark
#

what happens if i leave out the braces?

swift crag
#

A block statement has its own scope, as Steve said. Variables you declare inside of it stop existing once you leave it.

ruby python
#

Basically tells Unity that what is inside them belongs to the 'private void Start()' 'chunk' of code.

woeful hedge
swift crag
proven lark
#

oh okay

#

and what about this

image.png
#

why are there braces throughout everything

#

rather than just two defining start and finish

swift crag
#

You aren't allowed to declare a method without a body. You have to use { braces } to define a method body.

#

Hence the error.

polar acorn
ruby python
#

Because if, else if and else are essentially completely seperate from each other.

swift crag
#

if statements do not require this. They just apply to whatever the next statement is.

languid spire
#

because Scope can have many levels, in this case they are defining a Scope for the if statement

swift crag
#

A block statement groups many statements into one big statement.

proven lark
#

oh okay

#

i think i understand it now

swift crag
#

Without braces, you'd only ever be able to put a single statement after an if / else if/ etc.

polar acorn
#

The braces contain all the code inside them and basically turn them into one line. if statements apply only to the next line, if that line is a block, then it applies to everything in the braces

swift crag
#

which would be very limiting

woeful hedge
swift crag
#

they're just not in your screenshot

proven lark
#

yeah i know

swift crag
#

and a pair of braces that start and end the class you declared the method inside of

ruby python
#

If it helps, try to thing that anything inside the { } is 'written' on a post-it note of it's own. It's seperate from everything else, but you can cross reference.

proven lark
#

u guys are really helpful

#

tysm

chilly barn
ruby python
# chilly barn Exactly this yeah

Look at the code I posted, will need a little tweaking as I use an interaction script between the player and the vehicle, but it should point you in the right direction.

#

Learn things along the way

#

Plus then I have a bunch of placeholder code for common stuff I can cannibalize later

#

guys I'm actually gonna cry ok so my game is a 2d platformer and whenever the player dies it resets the scene (I didn't know how to make respawn points in the middle of development) the problem was that my audio reset so to fix this I made a don't destroy on load script but that also came with some problems for instance if I changed scenes the audio would still play creating more background music and them over lapping if you have any suggestions or things to help ping me pls!!

frosty hound
#

If resetting the scene is just a hack because you didn't want to just reset the level, then why are you trying to fix the audio reset as a result if you know you're going to change the restart functionality later?

you are only suppose to subscribe to your events once usually in awake or start

queen adder
#

ahhhh

eager elm
queen adder
#

thank you for the input i'll fix it as noted

#

hold

#

OK

#

ANYWAYS, i put the event subscribers in the start function and it still doesnt register the input of ToRun.

#

can anyone tell me why that is

slender bridge
#

and i changed my pic for you

queen adder
#

oh you didnt have to

dusty rivet
#

okay so i have got this class public class GameSettings : MonoBehaviour { public static Difficulty difficulty { get; set; } } and i want to right a script that changed the difficulty and this is what ive got GameObject.FindGameObjectWithTag("Settings").GetComponent<GameSettings>().difficulty = Difficulty.easy;

#

and for the difficulties i have an enum which contains the difficulties

#

but it doesnt seem to be able to change the difficulty in gamesettings

#

is it bc its static

#

if so is there a way i can fix it without making it non static

languid spire
#

yes

slender bridge
#

yes, use a ddol manager or store it in prefs

dusty rivet
#

ohhhh yeah i forgot abt prefs

#

how do i use prefs

#

coz ive forgot

slender bridge
#

PlayerPrefs.

eager elm
dusty rivet
#

alr

dusty rivet
slender bridge
dusty rivet
#

also do i need the difficulty varibiable to have the { get; set; }

eager elm
# dusty rivet thank you

And you could also use FindObjectOfType<GameSettings>().someVariable instead of looking for a GO and then looking for the component.

eager elm
dusty rivet
eager elm
# dusty rivet what does it even do

a property is basically a method that runs when you Set a variable or Get a variable, for example:

public int Health
{
    get { return health; }
    set
    {
        health = value;
        if (health <= 0) PlayerDies();
    }
}
private int health;```
Everytime you call Health -= 1; it checks if the health is below 0 and if it is it called PlayerDies();
dusty rivet
#

why is there two private int health?

dusty rivet
calm coral
languid spire
#

there actually aren't 2 int health's

dusty rivet
#

ohhh yeah ive just realised ones public ones priv

eager elm

#

also one has a capital H. case is important

alr thanks guys

thinking that the camera has to have an orbit around the car to always be aligned, but need some help with coding that

calm coral

and don't apply to the current api

short hazel
#

The JsonUtility API hasn't changed in forever, so doubt that

#

Are you using JsonUtility or something else?

calm coral
#

If I recall correclty JsonUtility has some limitations and doesn't fully export complex objects pepeThink it's good for small things though

burnt vapor
#

Some? More like a ton

short hazel
#

Yeah it's pretty limited, but for what they're trying to do it's sufficient

burnt vapor
#

It doesn't even have to be complex objects. Try serializing an array

#

Don't use JsonUtility, use Newtonsoft/JSON.NET

som like json 3.0 to json 4.0 or sum shit

I am trying to invoke a ManaRegeneration() method in the update function in an interval of manaRegenCooldown.
Expected Behaviour:
It increases the entityMana value every manaRegenCooldown seconds

Actual behaviour:
it waits manaRegenCooldown seconds and then increases the value every frame.

Here is the code:

[Header("Mana Stats")]
public float entityMana; 
public float maxMana;
public float manaRegenCooldown;
 
void Update()
{
  Invoke("ManaRegeneration", manaRegenCooldown);
}
void ManaRegeneration()
{
  if (entityMana < maxMana)
    entityMana += 10;
        
    if (entityMana > maxMana)
    entityMana = maxMana;
}```

#

i found it im jsut chaning something quickly

# 
        horizontalInput = Input.GetAxis("Horizontal"); //leftright
        playerRB.velocity = new Vector3(playerRB.velocity.x, 0.0f, playerRB.velocity.z);
        transform.Translate(Vector3.right * horizontalInput * Time.deltaTime * speed); //moves player
        verticalInput = Input.GetAxis("Vertical");//updown
        if (Input.GetAxis("Vertical") != 0.0f)
        {
            playerRB.velocity = new Vector3(playerRB.velocity.x, 0.0f, playerRB.velocity.z);
        } else
        {
            if (Input.GetAxis("Vertical") == 0.0f)
            {
                playerRB.AddForce(Vector3.up * (0 - 5), ForceMode.Impulse);
            }
            
        }
        transform.Translate(Vector3.up * verticalInput * Time.deltaTime * speed); //moves player
    }
}

Basically, I want to have a downard force constantly applying to an object which the player can move up,down,left,right (including up and left at same time and stuff like that), but I dont know how to change gravity on rigidbody without chaning mass (I do not want to change mass if possible). Solution was to not use gravity and instead use a constant downward impulse force that only applies if player is not moving upwards (i might change this so it will still apply but less force if player moves upwards). However if i click vertical force once the downard force stops applying (this is my issue). What is wrong in my code for the downard force to only work at start

#

this is in void update

wintry quarry
safe socket
#

I was chanign something else it wasnt mass sorry let me check again

wintry quarry
#

You also seem to be mixing Rigidbody motion with transform.Translate, which is a recipe for failure

#

Not only that but you're assigning y velocity to 0 every frame and then also trying to do jumping with forces

#

All in all it's kind of a mess at the moment

#

You're essentially mixing 3 different movement strategies in a way where they'll all clash with each other

timber tide
somber tiger
#

I tried it with coroutines as well, same result

#

does it have to do with calling it in Update?

safe socket
#

What is an alternative

pliant mist
#

I want to make something move around the radius of a circle based on mouse input i.e right mouse move right left mouse move left how do I do this? I’m sssuming some type of sin cos

safe socket
#

Im going to turn gravity off and stop the new assignment to velocty in every frame

summer stump
safe socket
#

why is rigidbody movement better than transform

summer stump
timber tide
somber tiger
#

So using a coroutine in Start() means that it will run all the time?

timber tide
#

yep, you do a while loop in the coroutine and it'll wake up every so often, do its job, then sleep

#

but make sure you're yielding correctly else you'll freeze unity

Hi! I cannot for the life of me figure out how to remove a component from a gameobject. The component is an interface script IAbility. Any ideas? This is the script I've tried but isn't working> void RemoveAbilityScript(IAbility ability) { if (!CanRemoveScripts) { return; } if (ability == null) { return; } string abilityName = ability.ToString(); var componentToRemove = GetComponent(abilityName); Destroy(componentToRemove); }

quasi plover
short hazel
molten horizon
short hazel
#

Okay so you need to remove one of the concrete components that implements the interface

#

You can make a generic method for this, with a type constraint

molten horizon
#

Maybe I could do GetComponents<IAbility>() and choose the one in that list because I know which one i need?

#

Nevermind that wouldn't work because I can't control the order

short hazel
#

void RemoveAbility<T>() where T : IAbility

#

Then GetComponent<T>() in it, and destroy that

molten horizon
#

Ok let my try that

short hazel
#

After that, you can call the method and pass the component type to remove, and with the type constraint, it'll produce a compiler error if you pass a type that does not implement the interface

molten horizon
#

the GetComponent<T>() calls an error "Cannot convert T to UnityEngine.object

short hazel
#

Show your updated code

molten horizon
# 
    {
        Destroy(GetComponent<T>());
    }
``` And here is where I assign the variable to be removed: ```

public void AssignAbility(IAbility newAbility, int abilityNum, Ability abilityForList)
    {
        abilities[abilityNum] = abilityForList;

        switch (abilityNum) 
        {
            case 0:
                RemoveAbility<ability1>();
                ability1 = newAbility;
                break;
            case 1:
                RemoveAbility<ability2>();
                ability2 = newAbility;
                break;
            case 2:
                RemoveAbility<ability3>();
                ability3 = newAbility;
                break;
        }
    }```
#

But that also calls an error because ability1 cannot be found

short hazel
#

Yeah generic types don't work like that, you cannot treat the things you pass in the <> as variables

#

So you cannot use generic types in this context

molten horizon
#

Ok, so what would I do? I've tried Type.GetType(ability1.ToString()); But it returns null so it doesn't work

short hazel
#

Revert to the old code, get all the components that implements that interface, loop through them, and do an equality check

#

Weird thing for abilities to be attached to game object though, usually they're simple classes stored in a list

eager elm
timber tide
#

usually you use generics to avoid these types of switch statements

#

I wouldn't suggest doing them if you're not well verse in them and just stick to comparisons for now

molten horizon
eager elm
#

and then using that as a parameter

molten horizon
eager elm
#

or, you add a method called DestroyMe() in your interface that you can then call.

molten horizon

ah ok

#

why is this not working i get the hit1 but not hit2

  Collider[] hitEnemies = Physics.OverlapSphere(transform.position, 2f, enemyLayer);
  Debug.Log("Hit1");
  foreach (Collider enemy in hitEnemies)
  {
     
      /*EnemyHealth enemyHealth = enemy.GetComponent<EnemyHealth>();

      if (enemyHealth != null)
      {
          enemyHealth.TakeDamage(punchForce);
      }*/
      Debug.Log("Hit2");
      enemy.GetComponent<Animator>().SetTrigger("Hurt");
  }
#

im hitting a enemy

slender nymph
#

apparently not

#

note that just because Hit1 prints, does not mean you are actually hitting anything

amber spruce
#

figured it out

#

i was trying to do it for 3d when my game is 2d

#

I created a base class for an item and insert that before the default time in Script Execution Order. Will that execution order affect the inherited classes?


[DefaultExecutionOrder(-10000)]
public class ItemBase : ScriptableObject
{ }

// Will it affect?
public class ItemInherited : ItemBase
{ }

// Both shown in the list inside Script Execution Order
slender nymph
#

it should, yes

#

also the attribute does not add them to the list in the script execution order settings

good evening all,
I've been throwing my head at the wall of 3d for a long time but looking to make the switch from 3d to 2d, I'm trying to avoid entering tutorial hell (again), any good written documents (not including the unity docs as im not sure how they piece together) about movement etc

I will admit i had a google but it just threw a mishmash of yt tutorials and uh, yeah i've watched too many lol

rich adder
#

the engine is 3D anyway

#

youll always working in 3d technically

unreal imp
#

guys this piece of code wont lag and executated every frame? I mean if it was executed only one time void Update() { if (Gun.GetComponent<Gun>().ammo <= 0 && !gun.GetBool("OutOfAmmo")) { gun.SetBool("OutOfAmmo", true); shootEmpty.Play(); } }

rich adder
#

GetComponent every frame 😬

I know, but i'm hoping to go into it from scratch.
I over scoped for my first few games, published a few but they were abslutely clusters and i followed a lot of tutorials (didn't learn much) So my knowledge is fairly scatter brained across a lot of random things

#

negative

#

You're calling it everyframe because that condition gets hit first

unreal imp
#

so how i should solve it?

rich adder
sour arch
#

Void lateupdate could work for that?

rich adder
sour arch
#

i think

#

yeah what dalphat said lol

rich adder
#

no you simply "Cache it"

#

yea

Hello. Can someone tell me pls if I can use the IgnoreCollision method to make the ray ignore objects with a specific tag. An example is below.

public class RaycastLearn : MonoBehaviour
{
    public string[] tagsToIgnore = { "Base", "Wall" };
    public GameObject[] objectsToIgnore;
    void Update()
    { 
        Vector3 rayOrigin = transform.position;
        Vector3 rayDirection = transform.forward;

        RaycastHit hit;

        foreach (string tagToIgnore in tagsToIgnore)
        {
            objectsToIgnore = GameObject.FindGameObjectsWithTag(tagToIgnore);
        }
        
        foreach (GameObject objToIgnore in objectsToIgnore)
        {
            Physics.IgnoreCollision(gameObject.GetComponent<Collider>(), objToIgnore.GetComponent<Collider>());
        }
        
        if (Physics.Raycast(rayOrigin, rayDirection, out hit, Mathf.Infinity))
        {
            Debug.Log("Hit object: " + hit.collider.gameObject.name);
        }

        Debug.DrawRay(rayOrigin, rayDirection * 10f, Color.green);
    }
}

these codes too? first code: ``` void Update()
{
if (Input.GetKeyUp(KeyCode.E) && !objectAnimator.GetBool("Flushing"))
{
objectAnimator = gameObject.GetComponent<Animator>();
ray = Camera.main.ScreenPointToRay(new Vector3(Screen.width / 2, Screen.height / 2, 0));
if (Physics.Raycast(ray, out hit, interactDistance) && hit.collider.gameObject == gameObject)
{
InteractWithObject();
}
}
else if (objectAnimator.GetBool("Flushing"))
{
objectAnimator.SetBool("Flushing", false);
}

    if (!toiletExplodes.active)
    {
        audi.Stop();
    }
 }``` second code: ```    void Update()
{
    if (Input.GetMouseButtonDown(0)) {
        Invoke("IsShootingTrigger", 0.1f);
    }
}```
#

It seems that my fears came true xd, every frame is executed this

rich adder
#

uh yeah whats the point of doing this at runtime

#

if the component is already on THIS object

unreal imp
#

welp i was trying to make a flushing animation on a toilet,simply that

dusty rivet
#

is there a way i can change the RectTransform.right value in code by itself
