Do they all explicitly set the state or do they just look at the state?

willow sand
#

theres 3 that control the sate like for example when it turns into the attack state and theres one that sets the target to attack and then theres one that set the attack output

astral falcon
#

There should be one source of truth about states. Other scripts just react to it. is that what you mean?

burnt vapor
#

Have you debugged these three with the log messaging or debugging I specified, and are you 100% sure that it definitely sets these animation states?

willow sand
#

you mean transitions?

Hi. quick question. I need a line of code, what add to this script for keep moving a player yValue position after click

using UnityEngine;

public class aabbaa1 : MonoBehaviour
{
    float xValue = 0f;
    float yValue = 0.1f;
    float zValue = 0f;
    [SerializeField] bool moveup;
    
    void Start()
    {
        moveup = false;
    }

    void Update()
    {
        if (Input.GetKey(KeyCode.E))
        {
            transform.Translate(xValue, yValue = 0.1f, zValue);
            moveup = true;
        }       
    }
}

That first link is pretty interesting

Hello! When I try to change the current scene from my game I have the error message:
"Scene 'MainMenu' couldn't be loaded because it has not been added to the active build profile or shared scene list or the AssetBundle has not been loaded.
To add a scene to the active build profile or shared scene list use the menu File->Build Profiles"

I'm using this method: "SceneManager.LoadScene("MainMenu");"

#

My projet look like this

image.png
#

I tried to add the MainMenu scene here but I don't see the MainMenu scene anywhere

image.png
#

Someone can help me please ^^ ?

green flame
#

Oh god thx! So easy I was 1hour on this thing xD Sometimes unity UI is a bit hard to understand ^^

runic lance
#

yeah, this thing is specially strange to use, no idea why you can't simply select scenes there

#

Uhh I got a map from the asset store and I don't know how to add the whole map to the game, it's now in my project thing

image.png
#

Why are the trees pink now 😭

flat sphinx
#

whats the syntax for
foreach(var thing in [x, y])

tawdry quest
# mint surge

The map wasnt made for your rendering pipeline, you need to convert the materials

flat sphinx
#

cuz that one doesnt work

tawdry quest
#

Foreach is different

mint surge
flat sphinx
burnt vapor
#

It's unclear what you want here, please be more specific

languid spire
burnt vapor
#

I doubt my code even works

#

No, definitely doesn't

languid spire
#

and some C# basics lessons would seem to be in order

burnt vapor
#

If the point is iterating a joined collection, then you probably need

foreach(var thing in x.Concat(y))
flat sphinx
burnt vapor
#

Don't ask how to do the solution, ask about the actual issue

#

From this it seems like you might want to invoke behaviour based on if you work with an even or odd number, but I doubt it

languid spire
#

do you mean
GameObject[] gos = new GameObject[2];
...
foreach (GameObject thing in gos) {
// Do Stuff
}

flat sphinx
#

why do i bother

Screenshot_20241213_143542_DuckDuckGo.jpg
burnt vapor
#

Don't know what you want us to say

#

Explain the issue instead of relying on AI

#

What are you trying to do that requires this?

languid spire
flat sphinx
# 
foreach(var thing in new[]{current_board.base_board, ball})
    yeet_up(thing)
#

is what i needed

verbal dome
#

Are you actually using it for just 2 elements or are there more?

flat sphinx
#

and now i have it

languid spire
#

and here
GameObject[] gos = new GameObject[2];
it's already there which if you are iterating over it is where it should be in the first place instead of creating an array on the fly

flat sphinx
burnt vapor
#

I don't see why you would iterate two hardcoded elements instead of just calling yeet_up twice

verbal dome
#

Alright. Tbh I never thought of constructing an array in the foreach loop's header

burnt vapor
#

But as long as you send tiny snippets of code and AI I don't think it really matters anyway

flat sphinx
#

for(var/thing in (x, y))

burnt vapor
#

That's a tuple, though

flat sphinx
#

its a list

burnt vapor
#

() makes a tuple, [] makes a list

flat sphinx
#

not python

#

there arr only lists

burnt vapor
#

Regardless () would make a tuple

flat sphinx
#

even assocs are lists

burnt vapor
#

Even in C# it would

#

Just fyi, because even your code doesn't do that

#

Modern .NET does allow [] to define collections

#

But I still don't see why you bother allocating an array for two known elements when you can just call a method on them directly

#

I'd love to help if you actually shared code

flat sphinx
#

somehow

burnt vapor
#

Well, explain the issue

#

Why do you need this?

#

The current code looks like overcomplication but I assume the point is for something bigger

mint surge
#

I added a pipeline and converted but some parts are still not rendered while some are, idk how to do it welp

image.png
verbal dome
#

Show the material of one of the pink objects

mint surge
swift crag
#

You need to select one of the objects with a renderer on it

#

They should all be children of this BLD_Bridge_A object

#

Then open its "Materials" list and double click on a material

mint surge
#

Well this is one

image.png
#

Wrong one

#

Done

flat sphinx
#

whats the non-blocking version of thread.sleep()

swift crag
#

what are you trying to actually do?

flat sphinx
#

need to wait some seconds for particles to finish and sleeping pauses the particles too

swift crag
#

you can use a coroutine to perform an action after a delay

flat sphinx
#

no they dont return a promise

swift crag
#

notably, you can yield a WaitForSeconds

the tower handles the spawnpoint and should handle the prefab where the projectile script is bind too but can t get it working to see the projectile in the game itself😅

#

like the connection between those 2 files isn t great but dunno how to fix it

wintry quarry
#

Using Enemy enemyManager = Object.FindFirstObjectByType<Enemy>(); doesn't make a lot of sense

#

what if there is more than one enemy?

#

Also why would something with an Enemy script on it be an "Enemy manager"?

#

Wouldn't that be a completely different script?

humble forum
wintry quarry
#

I would expect Enemy to be a single individual enemy

wintry quarry
#

Why don't you just use the Target?

humble forum
#

red lines are just debug lines for the range of the towers 🙂

humble forum
# humble forum

biggest bug for me right now is making the prefab appear i assigned

wintry quarry
wintry quarry
#

which it seems like you might have

#

which script(s) are on the enemies?
What does the Enemy script actually do?

swift crag
#

in which case you desperately need to fix the names of these classes

wintry quarry
#

It seems more like something that manages enemies

humble forum
wintry quarry
#

but that's not what the code will do, unless Enemy does not actually represent an enemy

humble forum
wintry quarry
#

And that object has... which scripts on it

swift crag
#

Enemy is definitely not an enemy, yeah

humble forum
#

and enemy wich does the rest with the enemy

swift crag
#

it has a list of "temporary enemies"

#

This thing needs to be renamed to EnemyManager or something similar

humble forum
swift crag
#

"both"?

humble forum
#

temporary and then normal enemy in that script

#

but what has that to do with the fireball projectile? cuz my naming convention might be cursed but the rest works?

wintry quarry
#

this is not correct in a 2D game

#

in a 2D game this is going to make the sprite rotate like in Paper Mario

#

and be invisible because you're looking at it on the impossibly thin paper side

#

to rotate it towards the target you would just do this:
transform.right = direction;

swift crag
#

LookAt is similar to transform.forward = target

#

but the "forward" direction in 2D points into the screen

humble forum
#

like this sorry im a bit confused

distant robin
#

hi can someone help me? i've made this full body fps by using fps controller by unity, changing the capsule with a 3d model from mixamo and adding triggers to the code for animation. i've attached the main camera to the head of the 3d model, apart from the eccesive head bobbing, my character always go towards right, (probably because of the animation), even if im just pressing w (like in this footage) can someone help me please? thanks

swift crag
#

ah, target is another Transform

#

you need a direction to the target transform

#

such as...

# 
target.position - transform.position;
#

and then you need to set transform.right, not transform.forward

wintry quarry
#

transform.right = direction;

#

you already HAVE the direction variable

#

There's a reason I wrote direction and not target

swift crag
humble forum
#

but needs to be 2d right?

wintry quarry
#

It's already 2D

#

what do you mean

humble forum
wintry quarry
#

It doesn't matter

#

What I wrote is what you want

humble forum
#

like this?

swift crag
#

you still call LookAt

wintry quarry

You have this

Screenshot_2024-12-13_at_10.00.30.png
#

that's not the same

humble forum
distant robin
#

it was the root motion option

wintry quarry
#

you could have left it where it was

rich adder
#

LookAt was literally overwritting anything you wrote above with that. transform.right = becomes useless

wintry quarry
#

because if it's above, you will get an error when it's too close

#

the position in the code of where LookAt was is fine, but LookAt was wrong

humble forum
#

so what could be wrong no with the prefab not visible in the game?

wintry quarry
#

If it's still not visible you need to investigate further. Run the game and pause it and look at the inspectors of the objects and see what's wrong.

#

The projectile could be behind another sprite for example

#

But without seeing your project it's hard for us to say based on code alone. We need to see the scene setup.

wintry quarry
humble forum
# humble forum

bind the fireball projectile to the tower and that has its own script

wintry quarry
#

That doesn't answer the question

#

We want to see the SpriteRenderer

I'm making a 2d endless runner game (totally not a google dino clone) and I have the script set the high score to the current score if the current score > the previous high score. The only problem with this is that I use ```cs
SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex);

 to restart the game after I die and this resets my high score to 0. Is there any way to preserve this integer even when resetting the scene or am I gonna have to figure out a new way to restart the game?
Here is the relevant piece of code in case it's needed:
```cs
 if (collision2D.gameObject.CompareTag("Obstacle"))
        {
            Time.timeScale = 0;
            deathScreen.SetActive(true);
            finalScore.text = "Score: " + currentScore;
            if (currentScore > currentHighScore)
            {
                currentHighScore = currentScore;
                highScore.text = "High Score: " + currentHighScore;
            }
wintry quarry

But I suspect you do have one

#

it's probably just on a child object inside the prefab

You need to pay attention to the sorting layers and order in layers of all your 2D sprites. That is how the drawing order is determined

how do i yeet an obj

if they're all on Default and 0 then it is just random which will draw on top

i wanna animate some objects accelerating along an axis

humble forum

You could use an actual animation or just modify the object's transform.position

humble forum
#

center to pivot and changing order layer to 5 didn t seem to matter tested both aside from eachother

rich adder
#

you also can do some Tweening @flat sphinx
(just interpolating position)

flat sphinx
#

as for animatinos idk how they work

verbal dome
#

You could simply have a float speed, every frame use speed = Mathf.MoveTowards(speed, targetSpeed, delta) to change the speed (accelerate), and move the transform to some direction multiplied by speed

#

Mathf.SmoothDamp is also a decent option depending on what you need

#

(Or Vector3.SmoothDamp)

looks like the child fireball is very far from the parent

#

aka the visuals are wayyy further than parent moving

humble forum
rich adder
# humble forum where can i find that?

the move Tool in unity (W key ). when you show gameobjects so we can see the pivots but looks like child is way far, look at the position, it should be 0,0,0 from parent

vocal wharf
humble forum
#

first pic was the child

rich adder
humble forum
#

but the parent should also be 0 0 0 or only the child?

rich adder
#

the parent can also be 0,0,0 doesn't matter, that gets assigned when you do Instantiate anyway

#

the child is the main importance, it should not be that far away from parent, especially if its the visuals

humble forum

but the speed very low so visible but seem very small lol

is scaling ok or is that bad?

Hey, I created json config for the unity gradient.
It works fine for the most part, but there is 1 small issue.
When I assign it to the vfx graph's gradient, it looks odd.
The issue is with the gradient mode.
As can be seen in the first picture, it's correctly loading the mode from config, here's the conversion code too:

        /// Implicit conversion to <see cref="Gradient"/>
        public static implicit operator Gradient(ConfigGradient g) => new()
        {
            alphaKeys = g.AlphaKeys.Select(key => (GradientAlphaKey)key).ToArray(),
            colorKeys = g.ColorKeys.Select(key => (GradientColorKey)key).ToArray(),
            mode      = g.Mode
        };

But when I assign it to the vfx gradient, even tho it shows Blend (Perceptual), it looks wrong.
Picture 2 is what it looks like when assigned, picture 3 is what it looks like when switched to something else and back to perceptual, basically how it should look like.
It's also not just a visual thing as it's applied to the vfx graph in the wrong way too.
Thanks in advance!

you need a bool / switch statement if you plan on taking over the movement to do a precise currentpos to dashPos

currently what im trying to do is just make a flappy bird like clone so its just my player jumping in place and the pipes spawn in on the right, move to the left and get destroyed. And if the player collides with anything it calls my gameover method in my GameManager script

rich adder
frail hawk
#

i knew you would say that lol.

#

either works

rich adder
#

timer is ok what if you decide to have pipes that speed up and slow down? now timer breaks

heavy knoll
frail hawk
#

no , did not mean timer i mean distance check or viewport. timer is really inaccurate after a certain amount of time.

#

i wuold not rely on it.

Generally asking, is there a significant benefit to using Arrays over Lists?

languid spire

cache the camera probably

supple oar
# rich adder yeah you should not be teleproting it with transform.position = use a rigidbody...

Just Tried this

    {
        if (Input.GetKeyDown(KeyCode.Space) && ((Input.GetKey(KeyCode.W))||(Input.GetKey(KeyCode.A))||(Input.GetKey(KeyCode.S))||(Input.GetKey(KeyCode.D))))
        {
            //dashPosition = dashTarget.transform.position;
            //transform.position = dashPosition;
            horizontal =  dashTarget.transform.position.x;
            vertical = dashTarget.transform.position.y;
            myRigidbody2D.velocity = new Vector2(horizontal * moveSpeed, vertical * (moveSpeed + 50));
        }
        else  
        {
            PlayerMovement cs = Target.GetComponent<PlayerMovement>();
            moveSpeed = cs.moveSpeed;
            transform.position = Vector2.MoveTowards(transform.position,Target.transform.position,(moveSpeed - 1) * Time.deltaTime);
        }
    }

great and we know what line 45 is how?

#

so myRigidbody2D is null

would probably cache camera in update
private Camera cam;

and in the if statement do a check to see if the game is over?

I'm trying to call a function from another script in the script that I'm currently coding. I referenced the gameObject that the other script is on, and I used .GetComponent<MyScript>().MyFunction(); to try to get the reference of the function in the other script but I just can't find a way to call that function. How do you do this?

rocky canyon
#

soo u used
theOtherObjectYouSaidYouReferenced.GetComponent<YourScript>().YourFunction();

#

that should would if the script is indeed on the other object... and has said function

#

and the OtherObject is indeed referenced

languid spire
vocal wharf
rocky canyon
#

ahh like caching just the function for later

vocal wharf
rocky canyon
#

i misunderstood

#

myAction(); <-- just like that

verbal dome
#

Yeah if you don't put () you will get a reference to the method

#

With () you will call the method instead

rocky canyon
#

neat..TIL

vocal wharf
cosmic dagger
rocky canyon
#

any reason u'd cache individual methods and not the entire class?

#

seems like more flexibility with the later

cosmic dagger
languid spire
rocky canyon
#

ohh makes sense 👍

cosmic dagger
#

possibly for callbacks . . .

languid spire
#

indeed

cosmic dagger
#

if you want its execution in line within code or after code from another method . . .

verbal dome
#

You also often see it when you subscribe to an event: cs SomeEvent += MethodToCallWhenEventIsRaised;Note how there's no () because you dont want to actually call/invoke it here

languid spire
#

it's great in, for example, a Coroutine if you want a callback at the end of the coroutine execution

What if I just do this

if (collision2D.gameObject.CompareTag("Obstacle"))
{
    gameManager.GetComponent<GameManager>().Death();
}

to call the method when I hit an obstacle?

rocky canyon
#

whats gameManager at the beginning?

languid spire
#

sure, that works

vocal wharf
#

gameManager is a gameobject that has the GameManager script attached to it

#

names are a bit confusing ig

rocky canyon
#

oh.. u know u can assign the GameManager script instead right?

#

GameManager gameManager;
then gameManager.Death();

#

but thats only if its available to do so with

vocal wharf
#

I tried but it didn't let me drag the script in the inspector

rocky canyon
#

u drag a gameobject w/ the script attached to that slot

#

not the actual script

vocal wharf
#

oohh

#

ok it works now thanks

rocky canyon
#

then u can avoid using GetComponent calls

rocky canyon
vocal wharf
#

it's weird though, my death method works when I collide with an obstacle but the PointScored method doesn't work. 🤔
Script on player that detects if I pass through obstacle trigger:

 private void OnTriggerEnter(Collider other)
    {
        if (other.gameObject.CompareTag("Obstacle"))
        {
            gameManager.PointScored();
        }
    }

script on GameManager object that is supposed to add points to the score:

 public void PointScored()
    {
        currentScore = currentScore + 1;
        currentScoreText.text = "Score: " + currentScore;
    }

currentScore is a public int that is supposed to be displayed in the score text (all the text objects and stuff are assigned in inspector)

#

my score counter on screen stays at zero even when clearing an obstacle

polar acorn
#

See if it's the value you expect

#

You might be overwriting the UI text with something else

vocal wharf
#

hmm PointScored method isn't even being called. I'll try debug logging some other stuff and tell you what I find

#

ok the player isn't detecting the obstacle triggers

#

all the obstacles have trigger colliders above them

rocky canyon
#

are they all tagged correctly as "Obstacle"

vocal wharf
#

yes

#

do you want the whole player script?

rocky canyon
#

it may help !code use an external paste bin site tho

eternal falconBOT
vocal wharf
#

it's basically just jumping, ground check, obstacle collision check and obstacle trigger check

#

DUDE I'M LITERALLY SO STUPID

#

I used OnTriggerEnter instead of OnTriggerEnter2D 😭

#

It works 😮‍💨

#

now I gotta figure out how to make my high score not reset when the scene is reloaded

cosmic dagger
#

how granular would any of you go when creating packages? i have separate packages:

  • Utils (extension methods)
  • Core (base/boiler-plate framework)
  • Timer (timer class for calling events during certain phases of a timer)

I have an ObjectPool (a group of scripts), and was going to create a separate package for it, but i'm curious if i should group it with the core framework and pile most, if not, everything into that package. what say y'all?

Is there a library that adds a method to do something when the hierachy changes/ children or parents are added or removed?

tysm

rocky canyon

only works in editor tho..

#

not sure what u'd do for runtime

plush zealot
#

I just want to resize a ui object when children are added/removed

#

what would I use for that?

rocky canyon
#

the code that adds or removes from the hiearchy could also trigger that

#

if ur talkin about just scaling UI when more UI objects are added.. theres stuff like LayoutGroups that u could use to automatically do that

stuck palm
#

I love when i get 40 errors after a code refactor and then i fix those 40 errors and then 20 more show up 😄

#

why dont they all just show up together?

rocky canyon
#

b/c some errors stop other errors from being found.

#

not until u fix some.. does it execute enough code to find the others

cosmic dagger
rocky canyon
#

im awful at it.. soo if u do figure out the "optimal" way to sort this stuff let me know 😅

cosmic dagger
rocky canyon
#

ur far too humble

plush zealot

#

ya, id use a vertical layout group for that

#

it'll automatically resize it however u need

plush zealot

ok and it doesnt inerfere with scrollrect?

rocky canyon

ohh.. that i dont know.. i think they can work in tandem. but not sure what all that involvs

In C# when you use a namespace, all the types in it are available to you, so it's equivalent to Java's *

magic panther
#

Yall why is the .point of my RaycastHit2D always slightly off? Like, when I BoxCast onto a collider, for some reason, the collision point is never the position of the collider combined with it's extents?

image.png
plush zealot
short hazel
rocky canyon
#

if u want u can clamp it to the nearest int

#

or decimal place if u wish

magic panther
#

damn

#

what's the best way to go about this

#

In a line like this (just in case) RaycastHit2D[] hitObjects = Physics2D.BoxCastAll(startPos, boxCollider.size, 0, direction, distance * Time.deltaTime);

supple sand
magic panther
#

this might be it

#

lemme check

supple sand
#

You only want to cast it a total distance that scales with frame rate?

#

Low frame rate = cast longer, fast frame rate = cast shorter

magic panther
#

no, but this was a minor issue, so thanks

#

but this is a major issue

image.png
supple sand
#

Whats an issue with that

magic panther
#

even with such tiny inaccuracies, you can get stuck in walls and floors

supple sand
#

You tested that hypothesis or you are assuming/ guessing?

#

float comparisions are usually using epsiolon comparisons so its accounts for that tiny inaccuracy

plush zealot
#

when changing the size by dragging the lower end of the object in the editor it changes the height automatically. What's the ratio for that?
Or is there a method that adjusts it automatically if the object is resized, that I can use in a script?

image.png
supple sand
#

You can use Mathf.Approximately

supple sand
magic panther
#

it's very rare

#

but it occasionally happens

plush zealot
supple sand
magic panther
#

I could check if the position is exclusive within the boxcast

supple sand
magic panther
supple sand
magic panther
#

I added this line when checking on the x axis (flipped x and y on the y axis): withinBounds = hit.point.y < startPos.y + boxCollider.bounds.extents.y && hit.point.y > startPos.y - boxCollider.bounds.extents.y;

ty for the tip

Hi ! Sorry to disturb, but I'm trying to make my enemy spawner spawn enemies faster and faster, so I wrote something then wanted to test, but it didn't go as expected... (see the last picture)

I would like to make enemies appear faster and faster over time. But to prevent it from becoming exponential, I wanted to do it by making it stagnate at a certain speed stage, but it seems it didn't work ? The seconds I make the game play, there's just an infinite amount of enemy going down 😭

more than one of your if statements can be true, resulting in multiple instantiated objects . . .

I know that its almost not readable and im really sorry for that but i was just testing something and i was wondering why doesnt it work, the script should change the color of the capsule to 1.0f and then when it hits 1.0f it changes slowly to 0.0f and again to 1.0f, but all it does is chaning the color to 1.0f and leaving it like that

#

any advices would be usefull

languid spire
#

first thing first, never check a float for equality

frosty field
#

what do you mean?

languid spire
#

dont you know what equality means?

polar acorn
frosty field
#

why is that?

#

and how to compare using matf.approximately

languid spire
#

in your case >= 1.0f rather than == 1.0f

#

because floats are almost never exactly equal the value you think they are

polar acorn
#

You might end up with 0.99999999997 instead of 1

#

But also in your case, you should be checking for greater than 1, since you have no control over the increments and it's unlikely to even approximately hit 1 depending on framerate

frosty field
#

ohh

#

i changed the if's to <= and >= and it does work perfectly now

#

thanks a lot

Err, why are fields not serialised when I extend Unity's UI Button

polar acorn
#

Did you get UI.Button or UIElements.Button

#

and what fields are you trying to serialize

spiral narwhal
#

Just the normal UI buttons

using UnityEngine;
using UnityEngine.EventSystems;
using UnityEngine.UI;

namespace DefaultNamespace

    public class HoldButton : Button
    {
        [SerializeField] private Image fillImage;
        [SerializeField] private float holdTime = 1.0f;
polar acorn
#

Ah, that's what you mean. Button has a custom inspector. You'll need to make your own custom inspector as well to add your fields to it

#

Or just make it a separate script that references a button and use the normal button component

spiral narwhal
#

Why would Unity do my dirty like that. thanks tho

slender nymph

i'm honestly surprised button isn't sealed. so many other unity components are

is there a way of refrencing a project's assets via code?

#

just FYI, that's the UIElements.Image object which is not the Image component you can use on a canvas.
but otherwise, there's addressables or you could create a scriptable object that stores that data

there's also technically Resources.Load but the other two options are typically better

No, the buildings are already placed on the map, I need to get the area that the house covers

#

so i just thought of getting the bounding box, which works as shown above, for axis aligned only

#

and since i cant use the Renderer i cant use localBounds and rotate them later

rich adder
opaque reef
#

im not going from localspace to world space

#

the bounding box is already being measured from world space

rich adder
#

right one of those

opaque reef
#

since im using the collider

#

the exact same happens

opaque reef
# 
            foreach (var houseObject in houses)
            {
                var collider = houseObject.transform.gameObject.GetComponentsInChildren<Collider>().FirstOrDefault();

                    var localCenter = houseObject.transform.InverseTransformPoint(collider.bounds.center);
                    TriggerEffectParameters param = new TriggerEffectParameters(id: (ushort)effectIds[UnityEngine.Random.Range(0, effectIds.Length)])
                    {
                        position = houseObject.transform.TransformPoint(localCenter),
                        scale = collider.bounds.size,
                        relevantDistance = 500f
                    };
                    param.SetRotation(houseObject.transform.rotation * Quaternion.Euler(-90, 0, 0));
                    EffectManager.triggerEffect(param);
            }```
rich adder
#

its the scale

opaque reef
#

yea but how exactly?

cerulean bear
# 
using UnityEngine;

public class oppSpawner : MonoBehaviour
{
    private int numOfOps = 5;
    private int[] ops = new int[5];
    public float startingPos = -10.43f;
    public GameObject spawnable;
    private Vector3 spawnPos = new Vector3();
    private Vector3 spawnRotation = new Vector3(180, 0, 0);
    // Start is called once before the first execution of Update after the MonoBehaviour is created
    void Start()
    {
        for (int i = 0; i <= numOfOps; i++)
        {
            spawnPos = new Vector3(startingPos, 4, 3);
            ops[i] = i;
            GameObject spacesh = Instantiate(spawnable, spawnPos, Quaternion.Euler(spawnRotation));
        }
    }
    // Update is called once per frame
    void Update()
    {

    }
}

why is my stuff spawning in the wrong spot

rich adder
# opaque reef yea but how exactly?

wel when I do usually BoxCollider.size usually it gives me local/transformed so maybe try throwing the TransformPoint on the size, keep the position center as the bounds.center

opaque reef
#

transformpoint transforms it from localspace to world space

#

my scale is already in world space

#

if i do this

#

this happens

image.png
rich adder
#

I mean Inverse

opaque reef
rich adder
#

oh shit.. well thats not right

opaque reef
#

wait now its just y and z thats wrong?

#

its like that uniformly for every house

rich adder
#

wonky

opaque reef
#

nvm

rich adder
#

rotation is good but size is whacked?

opaque reef
#

for the box of other buildings its just fucked

image.png
rich adder
#

ah yeah that wont do..simplify the outline of the buildings with a box collider? 🤷‍♂️

opaque reef
#

i cant really change the mesh renderer from the buildings

#

the issue isnt even finding the center

#

its just that when the collider isnt axis aligned the bounding box will try to be axis aligned(?)

#

and will just eb the correct size but 90 d or plainly twice the size it should be

#

and i cannot calculate it using localbounds since i cant access the renderer component of the building

rich adder
#

you might have to remap it yourself..

Should I use html for my websites and unity for my games respectively?

cosmic dagger

website for what?

tender breach
#

It's going to be art software for the website.

tender breach
cosmic dagger
#

art software? you mean you're making an art program using unity?

tender breach
#

For html it's going to be the art program.

cosmic dagger

i don't understand what you're doing? where does unity come into play (how does it relate to unity)?

I've been trying to fix the main menu for the past hour. Quite literally, the slots should be saved as slot1.json or slot2.json, or slot3.json, but no matter what i do it saves as slot4, and then it doesnt show up in the main menu (but it should). There is 100% a bug in the code, but i cant find it.

Im looking for something very specific and cant find any tutorials on it, does anyone know anywhere I could check to find a tutorial on how to make a flying bird controller as my player in 3D? As in you play as a bird and you fly up by flapping your wings and control direction by where youre looking etc

#

I hope that makes sense!!

cosmic dagger
uneven frost
#

planning on making a game where you play as a dove for my gf since she loves birds but I think i might be in over my head 😭

cosmic dagger
uneven frost
#

oh yeah that makes a lot of sense!!!

#

I didnt even think about it just being a normal player controller wiht just, flapping enabled

#

lol

#

sounds great!!

#

I will prpbably be coming by here a lot tomorrow and stuff when I actually start real work on the project, its currentyly 1:25 AM and I wannma go to sleep in like 30 min or so, so I'll start the coding tomorrow

#

wont get much done in 30 min haha

#

I'll do that :)

winged osprey
#

oh my god now the confirmation dialog doesnt show up i gonna jump into a volcano

forest summit
#

i see

#

does othergameobject refer to the object that is being collided with

steep rose
#

you could use oncollisionenter for simplicity (if using a rigidbody)

winged osprey
#

is it just me or there's not alot of 2,5D games tutorials in unity

forest summit
#

does this mean that the script is inside of the point or the player

winged osprey
#

like you move forward, backward, left, right but you cant jump or go down

forest summit
#

ah ok

winged osprey
#

yeah

#

something like that

#

yeah

#

Well i guess that could help me at some point

#

Wait, do you think it will look better when i make an animation for each direction of my character (WASD and diagonal directions) or just WASD

#

Cause that's rather important

#

The collisions will be rather easy

#

I think

#

i'll check it out rq

#

His character has only 2 movements, left and right, and when he's moving down it remembers the last direction he was walking in

#

Yeah

#

Im overthinking some things right now

rancid tinsel
#

why does this go off despite not clicking anything?

image.png
winged osprey
#

It's really hard to tell someone how his game would look like better when you don't know what's the game about haha

rancid tinsel
#

wait nvm im stupid

#

i was looking at the debug which always happens when the method is called...

#

🤠 been wondering why it isnt shooting

image.png
#

i didnt even have to run it

#

🤦‍♂️

flat sphinx
winged osprey
#

So like, when game is about slaying enemies on a non moving screen, that is one singular scene for now, the background is literally static, the best would be the 8directional movement i feel like, but then its thinking how to make the hand and the arts and the weapon, you'll have to draw 1 sprite 8 times, and then what about having to draw for example 50 weapons times 8

#

that just feels like too much

flat sphinx
#

yeah i guess it is segmenting your code but having a random function handle input only relevant to itself feels icky

rancid tinsel
#

i think it made sense originally but now ive gotten a bit lost with it

winged osprey
#

making my first game with such amount of things to do wasn't the greatest choice

#

well, i'll try my best i guess

#

i thought it'll be done by 24th december but we'll see

#

yeah not really haha

#

now watch 80 tutorials

#

i kinda realised the time it could take

#

the game idea is nice, everything is nice but now do it is just harsh

#

and it aint even for selling like

#

if i make the game i'll tryhard it myself

#

but like when you struggle with saving a file using c# and you have to write an entire AI for each type of enemy

#

aight imma stop complaining and get to work

#

fine 🖐️

rancid tinsel
#

im getting this error between the last 2 lines - any idea what might be happening? I dont have any Destroy() methods in any script yet

#

tbh it feels like the diagonal sprites aren't really adding much work, but then i look at the animator haha

but i think i messed up some refernece

cosmic dagger
#

probably missing a reference assignment then . . .

rancid tinsel
#

i was accidentally assigning a prefab in the scene

#

that i forgot to delete

#

don't ask me how 😭

winged osprey
#

@edgy sinew wait one more thing

#

it seems not right for some reason

#

Do you feel it or is it just me

#

cuz

#

it actually seems quite weird rn

#

yeah but the overall structure

#

ah i see it

#

i've noticed few mistakes rn

#

like you cant stop dodging

#

or

#

cant transition from left to down or up

#

oh i had a few broken things with the animations earlier

#

do i need to use the exit block

#

like when i go from dodge left to idle and transition it

#

go for the exit block or the idle state back

#

aight

#

thanks for the help though

rocky canyon
#

technically its against the rules to ping ppl not actively in ur conversation but I don't mind

#

i just got home from installing an axel on my car working in the cold.. soo my brain is spaghetti right now

cosmic dagger
#

i don't know about this "L-shaped rig," but the camera is just offset from the pivot point (center of rotation/movement) . . .

rocky canyon
#

KIA.. and complex enuff to wear me out.. gimme a second to read ur post and ill see what i cant do

cosmic dagger
#

yes, you set where you want the camera to be based on the center (pivot) point. you can move it to either shoulder, up, down, front, back, etc . . .

rocky canyon
#

OTS camera..

  • position is offset
  • slight or zero rotation (make the players centerline closer or at center
    for zooming
  • usually the cam moves closer to the character and/ or aligns directly behind the weapon/character
  • FOV does alot to help.. 30-40 degrees-ish?
#

the cursor/crosshair will be a big part of it too.. (tightening up the crosshair for example when zooming ADS)

#

as for rotation i dont ever remember the camera rotating up and down for any TPS games ive played lately

#

this was the last ThirdPerson mode ive played.. ^ not my favorite b/c when u zoom in u just go str8 to first person

#

soo im probably not the best to ask, heh

#

so i guess ya, ur centerline is to the right of the player

#

and then it acts as normal third-person..

#

the way i did it was a bit magic

#

the actual raycast came from the center of the camera.. (ignoring the player/gun everything)

#

soo it would be accurate.. theres edge cases where u have to solve.. like headglitching a corner for example

#

u wouldnt be able to get a hit.

#

my projectiles came from the gun.. and would just use LookAt() to fly towards the point my raycast says it was aiming

cosmic dagger
#

no, that's not what i meant. i was talking about the original pic you sent. the camera is just at an offset position from the pivot point (the transform or position at where the camera rotates). this can be the center of the player or where ever you want to rotate from . . .

rocky canyon
#

but i never really refined it tbh

#

why u want to add to ur suffering?

#

right hand camera.. left handed weapon?

forest summit
#

when i have a script inside of a game object, does gameObject directly reference the object the script is in?

cosmic dagger
#

don't they talk about that in the video you got the bow n arrow pic from?

rocky canyon
#

Camera-Gun Convergence

#
  • raycast from camera
  • align gun barrel to match raycast hit point
  • fire projectile from gunmuzzle
#

i still anticipate edge-cases to sort out

cosmic dagger
rocky canyon
# 
 if (Physics.Raycast(ray, out RaycastHit hit, maxAimDistance, aimLayerMask))
        {
            Vector3 targetPoint = hit.point;
            gunMuzzle.LookAt(targetPoint);
        }```
forest summit
rocky canyon
# 
        {
            // Default to aiming straight```
#

this is def something i'd need to tinker w/ hands-on tho

#

mmhmm make sure to test tho.. for different situations..

#

if i remember correctly when i did something like this.. i had to ignore times when the gun was less than so many units from a wall for example.. else the crosshair and raycast hit point was wildly different

#

i think in that case i just shot from the gun str8 forward.. but idk been a while

cosmic dagger
eternal falconBOT
forest summit
#

cause i tried installing the unity integrator however it doesnt seem to do much for me

cosmic dagger
#

yes, your IDE should have intellisense (along with auto-complete) . . .

cosmic dagger
eternal falconBOT
rocky canyon
#

yup that was pretty much my solution as well.. if u discover a better one i'd be happy to hear

#

for left handed guns (which i did experiment with) i'd move my camera to also be over the left shoulder..

#

ur original drawing confused me a bit

forest summit
#

using UnityEngine;

public class pointCollection : MonoBehaviour
{
// Start is called once before the first execution of Update after the MonoBehaviour is created
void Start()
{

}

// Update is called once per frame
void Update()
{
    
}
void OnTriggerEnter2D(Collider2D other)
{
    if(other.gameObject.CompareTag("Player"))
    {
        print("collected");
        Destroy(gameObject);
    }
}

}
does this look right for a coin collection script, its not working for me

rocky canyon
#

i found my example..

#

so yea, i was testing looking over the top of the car here

#

    // Update is called once per frame
    void Update()

why is my stuff spawning in the wrong spot

#

im just touching the coin nothing seems to happen

#

also how do you delete components off of an object?

cerulean bear
forest summit
#

yes they both do

#

yes

#

oh wait

#

maybe not

#

i just tested it with a rigid body

#

no difference

yeah its probably a small issue

well see

#

i did not

#

it works

if the error states the object you want to instantiate is null, then it's not finding the object/asset you're trying to instantiate. if this is not the full error, post a pic of the actual error message . . .

this is the full message

naive pawn
#

Resources.Load("GameAssets") is null probably

#

why not just add that gameobject as a reference though

plush zealot
#

because I'm assigning a sprite to a blank sprite renderer that's on a playing card's prefab.

#

the sprite changes depending on the card but the prefab stays the same

mental palm
#

Is There any way to make the resources folder accessible for players ? Or any other method to access the regular game data folder ? (I want my players to put in their own sprites)

plush zealot
#

from the server

mental palm
#

why would I host a server? 😭 that sounds way more complicated than just accessing the files! Like I want every player to add individual sprites to his game

#

Not to every other players game too

#

Or is server like a file thing ?

naive pawn
plush zealot

ah well if youre making a single player game you dont need one

I suppose woops

Hello, Quick question. Where to add in this script for example "speed" so that I can change the speed of this script? ```cs
transform.Translate(Vector3.up * Time.deltaTime);

naive pawn
#

there's no speed there

willow shoal
#

but where i should add

naive pawn
#

you'll have to add your own coefficient

willow shoal
#

ik

#

but where

naive pawn

thanks i will try this

#

quick question, currently as a beginner, for somehow my character is moving upward while pressing W not moving forward, how can I solve this. Had created and also implyed character inputs

naive pawn
#

wherever in the multiplication you want, since it's associative
multiplying a vector with a float is technically more expensive but it's not really gonna affect anything at this point

willow shoal
#

oh

#

ok

naive pawn
#

or your forwards direction is wrong

#

can't really answer much without any detail

little hornet
naive pawn
#

!code

eternal falconBOT
little hornet
#

idk if this is the right code or not

#

I used the default Character Input Unity had provided, might could be the issue

naive pawn
#

oh you don't need to show this

#

that's generated

little hornet
#

here is a picture of the bindings

Code.png
naive pawn
#

show what you're actually doing to move

little hornet
#

this one is the the PlayerMotor

naive pawn
#

so you're doing 3d right

#

y is up

#

a Vector2 is x and y

#

you don't need to assign the x and y manually here btw, you can just construct it directly

#

if you were to keep the x/y binding, you could also just Vector3 moveDirection = input; but here you need to remap it

little hornet
naive pawn
#

so it'd be Vector3 moveDirection = new Vector3(input.x, 0, input.y);

#

also pretty sure you don't need the transform.TransformDirection there

little hornet
#

I'll change it and see the result

#

should I delete the ```cs
moveDirection.x = input.x;
moveDirection.y = input.y;

naive pawn
#

yes, since now you're just creating the vector directly

#

i'd recommend using !learn

How do I find out if an object is not destroyed?

foreach (var interactable in _interactables.Where(it => it is not null)) interactable.enabled = false;

I have some interactables that are destroyed at runtime without notifying this script

#

Actually nvm I think it might be != instead of is not because of the unity stuff

north kiln
#

Yes, you can't use modern null checking operators

spiral narwhal
#

Yeah time for Unity to step up its game

#

It's ages behind lol

north kiln
#

their approach is incompatible with the operators, the API would have to be changed entirely

#

as it would break so many things, I'm not sure it will ever happen

#

but we can hope the next gen Unity has some changes

how to stop a player when he touch a block? or he is close to boxcolider block/object ```cs
public float speed;

bool MoveRight = false;
void Update()
{
    if (Input.GetKeyDown(KeyCode.Space))
    {
        MoveRight = !MoveRight;
    }
    if (MoveRight)
    {
        transform.Translate(speed * Vector3.up * Time.deltaTime);
    }

    else if (!MoveRight)
    {
        transform.Translate(speed * Vector3.down * Time.deltaTime);
    }
}
#

i try use box colider but he goes through the wall

You'll move through the wall if you're teleporting otherwise (that's what changing-position/translation with Transform does)

ok thanks

Should I abuse FindFirstObjectByType<> as a way to set reference ? What is the best way to refer to something else ?

no, just set it directly in the inspector
