sigh quaternions here I come

plucky karma
#

The way I understood quaternions is that there's two set of angle, and two set of distance. The angle helps rotate initially, then the distance tells you how far you are on that angle. Then repeat for the second angle, which gets rid of the third dimension entirely (effectively removing gimbal lock)

shell scarab
#

I'm going to be honest

#

that doesn't help me understand them more

#

I'm getting more of a feeling for using them though.

plucky karma
#

It's complicated, have you try using TransformPoint?

shell scarab
#

yes it happens with TransformPoint too

plucky karma
#

What about LookAt()?

shell scarab
#

yup

#

🥲

#

it's fine. i've been dabbling in Quaternions a little bit. I don't need to fully understand them just yet, I just need it to work... i can understand them later

plucky karma
#

Quaternions are fun and powerful if you really understand. It's like a matrix4x4.

So i'm just trying to change color of a 2D Sprite Renderer, and then here's what happens:
They turn invisible.

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

public class Teleporter : MonoBehaviour
{
    public GameObject opposingPortal;
    public bool ChangeColor;
    public Color32 colorToChangeTo;
    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        
    }
    void OnTriggerEnter2D(Collider2D other)
    {
        if (other.gameObject.tag == "Player") {
            other.gameObject.transform.position = opposingPortal.transform.position;
            if (ChangeColor) {
                other.gameObject.GetComponent<SpriteRenderer>().color = colorToChangeTo;
            }
        }
    }
}

Code for refrence.

just configuring it won't magically fix the issue. it will just show you where the issue is.

hah was it @leaden ice and @heady iris i was talking with about the mapmagic2 issue? praetor your suggestion to reach out to denis worked - funny update to the story - so i reached out to denis asking if he had any tips - in the meantime, i figured out how to write a custom generator node for mm2, and had a hacky solution that just used it to write to a scriptable object - but then denis got back to me, we exchanged some emails, and he said that spline output node should be working? i pointed out where it wasn't, he apologized and sent a new (working) version of SplineOut, lol

Hey, this might be a bit of an abstract problem but I'm making an RTS and I want to make it so that when you set a unit to attack another unit, it will automatically find a a soldier to target while staying in formation. Here, for example, each soldier will be assigned to a target with an index across from it, which is pretty easy when dealing when units of the same size (and using dot products to check if the order should be reversed)

image.png
#

But the problem arises when you try doing this with two units of different sizes

image.png
#

with the current approach, they will end up crossing each other

#

so this is what happens with units of the same size

image.png
#

and this is with different sizes

image.png
#

sorry for the spam

#

but I'm looking for a way to have them find a target directly across (or at least one that doesn't require crossing)

#

each unit has values for unit size, depth and length

Using Buttons with both Sprite Swap and keyboard input, is this possible?

# tepid charm that could work, though I'd imagine it would be quite a heavy calculation for la...

Yeah, it would be quite expensive for huge squads. I suppose it could be sped up by somehow dividing the squad into subsquads. If the performance was an issue, you could try some quadtree implementation, so you could check only units from a particular map area.

If you want a simplified approach, I would suggest calculating targets only for corner soldiers, and then try to set other targets analogically. If a unit from position x1, y1 targets a unit from position x2, y2, then a unit from position x3, y3 would probably want to target a unit from position x3-x1+x2, y3-y1+y2. The results should be decent as long the formation is regular - any bigger noises could make targeting look noisy.

see how matrices work in mathematics and you'll stop hating "C# matrices"

you could try using the experimental 2D lighting that comes with URP

I am trying to setup a VR script that looks in a certain direction and if it hits a box collider in layer 8 that it will print out Looking at Watch

image.png
#

The problem atm is if I am not looking at the watch it will still say looking at watch. Anyone know why?

cobalt wave
#

is the watch on a wall?

#

or is it staring into nothingness

timid meteor
#

so no it's on the player's hand

#

this is vr

cobalt wave
#

hmm

#

myb i should inspect the code a bit more lul

#

also, why do you 1 << 9 if you want the 8th layer?

timid meteor
#

// Bit shift the index of the layer (9) to get a bit mask

cobalt wave
#

also

#

uhhh

#

it's because you say "else, debug.log("Looking at watch")"

#

it will debug the same thing no matter what

timid meteor
#

omgosh

cobalt wave
#

it happens

timid meteor
#

XD

#

Ah well I still found a slight issue

#

could hit.distance be the cause?

So many comments in your Update() method. If your layerMask is never going to change anytime during your game runtime, might as well cache the result and use it as a reference.

#

Or make your LayerMask an inspector value to change/adjust.

I'm instancing a bunch of game objects at runtime. Is it possible to make a prefab of the scene(partof) and still keep the instanced prefabs link intact?

timid meteor

set it to layer 9 and called it watch

it's not needed

you can use both

timid meteor
cobalt wave
#

well then I'm 99% sure it collides with the camera's collider

timid meteor
#

hmm if it's on the camera wouldn't that not be part of the objects it hits?

cobalt wave
#

make sure to shoot the ray outside the camera's collider, or do Physics.IgnoreLayer or something like that and ignore the camera

plucky karma
#

the layerMask would've omit the collision..

#

Does the watch have collider as well?

timid meteor
cobalt wave
#

actually, it almost never did that for me

timid meteor
#

but it can't have a rigidbody because that messes with the VR hands

sly slate
# plucky karma Yes?

@quaint pine okay, I hoped so... How ?
if I create a gameobject by instantiate and reference a prefab it looses its reference once its in the scene

plucky karma
#

It should work... You have debug.DrawRay, whatwhere does it hit?

timid meteor
#

yes when I start the game on unity I can see it move around but I don't see it in the head set

#

so it aims and changes color

#

but doesn't activate for some reason

hey, does anybody know how to create the instance of GameObject without Instantiating it and without changing the original prefab?

            enemy.transform.position = currentPos; // or/and this one

        bool OnIsland(Vector3 position) => Physics.Raycast(position, Vector3.down, 1f, LayerMask.GetMask("Island"));
    }

#

what

plucky karma
#

We look at your code that only tell us that the raycast hit hits only your watch, but when you say "activate" what do you mean? Are you trying to invoke something on your watch?

timid meteor

is that when the player looks at the watch a hud will appear

yes but

#

what do you mean

#

by activate

plucky karma

#

what does activate at this moment

timid meteor

what I am trying to do right now is just get it to say debug.log("looking at watch")

"Looking at watch"

then just Debug.Log(hit.gameObject);

Instantiate creates a copy. You can't access information within prefabs if they're not initialized, otherwise you're directly modifying the "source" prefab object.

It's used as a template . . .

cobalt wave

why do you not want to use the Instantiate method so much

What exactly are you trying to do?

Do you need an actual GameObject or a MonoBehaviour class. You can create instances in memory with c# classes . . .

how?

what exactly do you need though

this is starting to sound alot like you need ScriptableObjects

cobalt wave
sly slate
#

my scenario is a bit complicated.. I got an ingame-editor that can create levels by using instantiating prefabs... Now I want to load up the game in the editor, create a map. Grab an entire map or part of a map in the hierarchy and create a prefab of it (this works fine) but all the items inside the new prefab are only clones.. would be nice if the prefab references where intact and only a couple of overrides applied to them

cobalt wave
#

I'm so confused, do 2 people have the exact same problem? lmao

sly slate
#

seems like it 😄

cobalt wave
#

I mean, why would it be nice?

#

it seems to me like you have it working

sly slate
#

then I could change a chair or something.. then it would change the chair prefab.. and update all the rooms that use the chair

cobalt wave
#

the prefab references are intact wdym

#

yes you can already do that

#

just change the chair

#

in the editor

sly slate
#

If I had done this in the editor.. it would work. But the problem is that I am creating the world using my own in-game editor

#

so I fire up my in-game editor.. grab my room that i want prefabed. But the chairs and stuff are all just clones by now

#

since they are create using Instantiate

cobalt wave
#

I think you need a "Load" function

sly slate
#

yes... that's a good idea. I guess I could write an editor script to use my existing load function

#

😄

plucky karma
#

Wouldn't it be easier if you'd just create a prefab of the level, so that you can just drag and drop into your scene?

cobalt wave
#

it appears they don't want that functionality though

rain minnow
gray mural
# cobalt wave great, what

I need to create enemyPrefab in the Scene on the the hexagon, not rectangle. So I have (float min, float max) x and z positions (tuples) to create like if it's rectangle.
But to avoid creating enemyPrefabs where they just fall nowhere, I do check if they are on the floor with Physics.Raycast with while loop, if they are, I just break that while loop and create enemy on that nice position, where they do not fall.
The Raycasts are gone from enemy's bounds, but to get those bounds, I should GetComponent<SphereCollider>() of enemyPrefab. To do it I need to Instantiate it. But? It instantiates in the scene then. To avoid that I just create GameObject instane, but this also changes original enemyPrefab.
And now the question: How can I do the same without changing original enemyPrefab position?

cobalt wave
#

yes

#

Instantiate it

gray mural
cobalt wave
#

you are doing something secondary that changes the prefab's position

plucky karma
#

Ideally, if you know that the enemy must spawn on hexagon shape, then I would create a manager to keep track of all existing hexagon shape, that the enemy can spawn on. Then your manager would expose method implementation to receive coordinate, which will check any existing hexagon shape that matches that coordinate and spawn it. Otherwise, skip.

cobalt wave
#

ah

#

I see

#

@gray mural you need to change the position after you instantiate the object

#

sort of like this

gray mural
cobalt wave
#

GameObject go = Instantiate(prefab);

#

no

#

just

gray mural
cobalt wave
#

do the other stuff

#

after that instantiation

#

everything you do in the while loop

gray mural
cobalt wave
#

do after

#

sees what

#

it won't see it

gray mural
#

enemyPrefab

cobalt wave
#

it can't see in a frame

#

even less

#

just

plucky karma
#

Disable the gameobject after you spawn it, so that the player can't see it?

cobalt wave
#

it's the same

sly slate
#

@quaint pine yes.. that is pretty easy, the problem comes later if I want to update some item inside the room.. it would have lost its reference

plucky karma
#

How would you update the item if it didn't have reference initially???

#

You'd only lose reference if you override the reference. Then that's a dangling reference problem.

sly slate
#

yes, that's why I was asking about how to Instantiate without making a copy 🙂

#

didn't proofread it

#

but this is the logic

#

it's exactly the same

#

except it does what you want it to do

#

you could also put this line GameObject enemy = Instantiate(enemyPrefab, currentPos, spawnRot, enemiesDocument.transform); inside of the while loop

plucky karma
#

Needs enemy.SetActive(false); until it finds a place to stand on.

BUT IT WONT BE THERE

#

do you understand

#

how unity works

gray mural
#

ah

cobalt wave
#

and how pc's work

#

the entire script

#

is swept

#

from top to bottom

#

in one frame

#

you won't see the enemy spawned at 0,0,0

#

the while loop has to finish in the frame and if it doesn't, you get a frame drop, simple as that

#

fps drop*

gray mural
#

I just gonna let it as it is, I sure do not need enemyPrefab's position

cobalt wave
#

because it takes longer to finish the frame

gray mural
#

The player does see that frame

cobalt wave
#

no

#

they

dont

it gets spawned at 0,0,0
then it gets manipulated

ok I gonna prove it to u bro

what the player sees? whatever happened after the manipulation!

#

please do

gray mural

ah no

#

I won't

because I have 200+ fps there and I cannot see it

no

but because

gray mural

but if I had 50 fps, then =>

cobalt wave
#

you don't understand how processors work and how they carry out instructions

#

the entire script

is done in one frame

meaning that if the last bit of the script "moves" the enemy, that's where the enemy is going to be

ok so the issue seems to be that

the component can not be accessed from another script for some reasons

it can be accessed from the script in the gameobject the component is in

show your code.

#

enemyhitboxes= enemyylist.transform.Find("hitbox").GetComponent<BoxCollider2D>(); one of the many examples that brings an error

this only happens in build mode not in editor

i think its an access issue

as in the scripts cant access anything in another gameobject for some reason

I mean in code

?

cold parrot
#

Without the right click

rustic ember

this.Reset() ?

Does that reset a script?

Looks like its for MonoBehaviour only

It sets all serialized fields to their default values or runs whatever overrides you’ve implemented

Great great

#

Thank you all 🙏

somber nacelle
#

however i'm not sure if calling it manually is going to reset it's serialized fields

hexed pecan
#

So idk if calling it manually would do anything

cold parrot
#

Btw, you should not be overwriting serialized values. So in a properly implemented SO, this wouldn’t come up

hexed pecan
cold parrot
#

you would have to implement the reset ofc

hexed pecan
#

Yeah I dont know if manually resetting every member in the code is what hes asking for

cold parrot
#

maybe like this ```cs
public class MySO : ScriptableObject, ISerializationCallbackReceiver
{
[SerializeField] private float foo;

    public float Foo { get; set; }

    private void Reset()
    {
        Foo = foo;
    }

    public void OnBeforeSerialize()
    {
    }

    public void OnAfterDeserialize()
    {
       Reset();
    }
}

Why do I have infinite while loop?

private void SpawnEnemy()
    {
        GameObject enemy = Instantiate(enemyPrefab, Vector3.zero, spawnRot, enemiesDocument.transform);

        while (true)
        {
            enemy.transform.position = new (TupleRange(spawnPos.x), spawnPos.y, TupleRange(spawnPos.z));

            Bounds bounds = enemy.GetComponent<SphereCollider>().bounds;

            Vector3 topLeft = new(bounds.min.x, bounds.min.y, bounds.max.z);
            Vector3 topRight = new(bounds.max.x, bounds.min.y, bounds.max.z);
            Vector3 bottomLeft = new(bounds.min.x, bounds.min.y, bounds.min.z);
            Vector3 bottomRight = new(bounds.max.x, bounds.min.y, bounds.min.z);

            if (OnIsland(topLeft) && OnIsland(topRight) && OnIsland(bottomLeft) && OnIsland(bottomRight)) break;
        }

        bool OnIsland(Vector3 position) => Physics.Raycast(position, Vector3.down, 1f, LayerMask.GetMask("Island"));
    }
#

I have done as guys before suggested me

somber nacelle
#

because you typed while(true) and your if statement at the bottom is never true to break out of the loop

gray mural
#

why is it never true?

#

it was true in my previous version of code

somber nacelle
#

well when could the bounds on the enemy sphere collider change during that loop?

#

since this is not a coroutine that is yielding no other code besides this loop is running for the duration of the loop

gray mural
#

this one worked very well:

private void SpawnEnemy()
    {
        Vector3 currentPos;

        while (true)
        {
            currentPos = new Vector3(TupleRange(spawnPos.x), spawnPos.y, TupleRange(spawnPos.z));

            GameObject enemy = enemyPrefab; // need to change this one

            enemy.transform.position = currentPos; // or/and this one

            Bounds bounds = enemy.GetComponent<SphereCollider>().bounds;

            Vector3 topLeft = new (bounds.min.x, bounds.min.y, bounds.max.z);
            Vector3 topRight = new (bounds.max.x, bounds.min.y, bounds.max.z);
            Vector3 bottomLeft = new (bounds.min.x, bounds.min.y, bounds.min.z);
            Vector3 bottomRight = new (bounds.max.x, bounds.min.y, bounds.min.z);

            if (OnIsland(topLeft) && OnIsland(topRight) && OnIsland(bottomLeft) && OnIsland(bottomRight)) break;
        }

        Instantiate(enemyPrefab, currentPos, spawnRot, enemiesDocument.transform);

        bool OnIsland(Vector3 position) => Physics.Raycast(position, Vector3.down, 1f, LayerMask.GetMask("Island"));
    }
gray mural
somber nacelle
#

that doesn't change the fact that if your if statement is never true the loop will never end meaning no other code will run. so if that if statement is not true the first loop how could it ever be true on following loops?

gray mural
#

cause

#

i mean

gray mural
somber nacelle
#

then use the one that works if you are so sure it isn't an infinite loop

ohhhhhhhhh

thank you

you need to find just one

I completely missed that

or make it GameObject.FIndGameObjectsWithTag("LogicManager")[index]
(I hope it is array)

but you'd better not

grizzled bronze

been skipping back and rewatching this video for the past 30 mins trying to figure that out

you'd better read error massages

first find GameObject

then GetComponent

just in case you messed something else up

gray mural
#

does Debug.DrawRay work in non-update function?

somber nacelle
#

yes, why wouldn't it?

gray mural
#

cause it does not work in my case

# 
if (OnIsland(topLeft) && OnIsland(topRight) && OnIsland(bottomLeft) && OnIsland(bottomRight))
            {
                Debug.DrawRay(currentPos, Vector3.down * 2f, Color.green);
                break;
            }
            else
            {
                Debug.DrawRay(currentPos, Vector3.down * 2f, Color.red);
            }
somber nacelle
#

well keep in mind if you still have an infinite loop how do you expect the frame to progress to actually draw the rays?

gray mural
#

i don't have

#

i have changed it

#

everything works perfect

#

expect those rays

somber nacelle
#

and how often are you calling the DrawRays? because you haven't set a duration which means it only lasts for the frame you call it on

gray mural
#

oh

#

how to I set direction to infinite?

#

not float.MaxValue i guess

somber nacelle
#

i mean infinite might be a bit much, but you can provide a decent number to the duration parameter to keep it up for a bit

ok

How do I scale UI properly across all/the majority of mobile devices

#

Cuz it seems like a lot of phone/tablet screen resolutions are very very different

#

should I just aim for a few mobile devices when creating an app instead of all of them

simple egret
#

Canvases have options to scale them with the screen size. Then it's a matter of anchoring your UI objects correctly so they're always in the right place whatever the screen size is

heady iris
#

you can use the CanvasScaler in "Scale With Screen Size" mode.

#

and then, yes, it's all about anchoring and positioning the pieces correctly

Canvas Scaler, Explained | Unity Tutorial

Learn all about the Canvas Scaler! The Canvas Scaler comes by default whenever you make a Canvas in Unity, but many of us don't fully understand how it works or what it does. When making a game, ensuring your UI scales reasonably across multiple different aspect ratios and screen resolutions is critical.

In this video we'll dive deep into each...

Hey, I have a question regarding combining multiple rotations, so if anyone has knowledge in the area, I would really appreciate some help.
I am making a 3D game that has the player walk around spherical planets. This is the player rotation code (in the Update method) that smoothly rotates the player based on my input vector:

if (input.magnitude >= inputThreshold)
        {
            float targetAngle = Mathf.Atan2(input.x, input.y) * Mathf.Rad2Deg;
            rb.MoveRotation(Quaternion.RotateTowards(transform.rotation, Quaternion.Euler(0f,             targetAngle, 0f), rotationSpeed * Time.deltaTime));
        }

And this is the code for the player movement, which is in FixedUpdate:

if (input.magnitude >= inputThreshold)
        {
            rb.velocity = transform.forward * speed * Time.deltaTime;
        }

And this is my poor attempt to align the player to the ground using a raycast's normal (which is inside FixedUpdate):

RaycastHit hit;
if (Physics.Raycast(transform.position, Vector3.down, out hit))
  {
    transform.up = hit.normal;
  }

Understanding and utilizing Quaternions is my weakest area in game dev, so all of my attempts of using things like Quaternion.FromToRotation and Quaternion.Lerp have led to very broken results. If anyone has a solution or could even point me in the right direction of how I could achieve this surface alignment system, I would be very grateful :)

#

sorry, long question ;_;

heady iris
#

Setting transform.up should do the trick.

#

If you do want to compose Quaternions, you can multiply them together. This gives you the result of applying both rotations.

#

However, rather than raycasting to the ground, I would rather just calculate the vector from the planet's center to myself.

#

otherwise, gravity will point all over the place as you walk up a slope

#

also, Vector3.down will shoot a vector in the -Y direction. I'm not sure if that's what you want.

steady moat
heady iris
#

if you are standing on the "bottom" of a planet, it will shoot a ray into space

steady moat
#

Like @heady iris said, you should use the closest planet to define the down. You could alternatively, use a whole bunch of calculation to add the gravity and figure out the highest gravity.

versed marsh
versed marsh
#

alright so I have this now in a seperate script:

[SerializeField] private Transform planetCenter;

    void LateUpdate()
    {
        Vector3 playerToCenter = planetCenter.position - transform.position;
        Vector3 newUp = -playerToCenter.normalized;

        transform.up = newUp;
    }

this does align the player with the planet's center, but since its directly modifying transform.up it just ignores the input-based rotation code I had before, and I'm not sure how to get around that

sly gate
#

so, i got a small tower defense game goin on where you can freely place walls to block enemies, the walls work by having the component navmeshobstacle with the carve option ON, but now i want to add "flying" enemies which are supposed to just ignore and go over walls like theyre not even there. How can i achieve this with the walls blocking the navmesh?

latent latch
#

Layer masks?

heady iris
#

yeah, you want to add a new kind of area

sly gate
latent latch
#

Oh, you're not treating the walls as obstacles but carving a zone out

sly gate
heady iris
#

if you use the new AI Navigation package, you get Nav Mesh Modifiers, which I'm pretty sure can target just one kind of area

#

o wait

sly gate
heady iris
#

is this a third-party thing? I don't recognize NavMeshSurface2D

somber nacelle
sly gate
heady iris
#

yeah, but I didn't think it had a separate surface type for 2D

sly gate
#

so should i just change how the walls work?

heady iris
#

can you show me this nav mesh surface?

sly gate
heady iris
#

...what is this?

somber nacelle
#

oh wait, is that from NavMeshPlus?

heady iris
#

yeah, this is third-party

potent sleet
#

the github one

heady iris
#

lmao, i like the readme image

#

get that pepper

sly gate
#

i honestly did that so long ago i dont evenremember

heady iris
#

i have no idea about how this thing works

potent sleet
#

i just use the 3D navmesh with sprites lmfao

heady iris
#

but yeah, if you switch to the new AI Navigation package, you can get Nav Mesh Modifier Volumes

#

which can target specific kinds of areas

#

so, you'd have a Flyer layer that isn't affected

sly gate
#

time to start from the beginning!!!!

#

awesome

heady iris
#

well, it shouldn't be that bad :p

sly gate
heady iris
#

what version of unity are you using?

sly gate
#

2020.3

heady iris
#

AI Navigation only left experimental in 2022, iirc, but it is available back to 2019

sly gate
#

i dont think i see it in the package manager though

potent sleet
#

add package by name

#

com.unity.ai.navigation

heady iris
#

guess what was only made possible in unity 2021

#

back in 2020, you have to manually edit the package manifest

#

extremely goofy

sly gate
heady iris
#

it's not hard by any means, but just goofy

#

although

#

since you do have this NavMeshSurface2D

potent sleet
heady iris
#

i wonder if you could just put down two of them

#

but the nav mesh obstacle would hit both...

potent sleet
#

is the game top down or sum?

sly gate
#

this is straight up not worth my time honestly

heady iris
#

actually, I am curious

#

is there a component named "nav mesh modifier" ?

#

if so, you're good

sly gate
heady iris
#

cool, there you go

#

that's what you'd be getting from the new package

#

I guess they've been backporting the features to this NavMeshPlus thingy

#

the modifier volume would probably be the easiest to use

#

you give it a volume and then tell it which areas to affect

sly gate
#

i remember trying to use it and having trouble with it, i dont remember exactly why though

heady iris
#

oh wait, that might require you to re-bake the mesh

sly gate
#

guess its worth a shot

sly gate
#

like. the wall's mesh?

heady iris
#

the navmesh

sly gate
#

doesnt sound to complicated

sly gate
heady iris
#

it's not bad, yeah

sly gate
#

ok... ill try switching out the obstacle component for the modifier and see if the wall still actually works for ground enemies

#

wait, the navmeshmodifiervolume is only for 3d right?

heady iris
#

you'd need to read the docs for NavMeshPlus to be sure; I'd expect it to work

sly gate
#

ill just use the normal navmeshmodifier for now

heady iris
#

oh, "volume" just means you give it an explicit region that it works in

#

i think the regular modifier is based off of the thing you attach it to

sly gate
#

@heady iris you still there?

#

tried it with the volume too that also didnt work

#

@heady iris ??

transform.localRotation = Quaternion.RotateTowards(Quaternion.LookRotation((follow.position + follow.forward * 2.5f - transform.position).normalized, Vector3.up) * Quaternion.Euler(0, 0, follow.localEulerAngles.z), rotateSpeed * Time.smoothDeltaTime);

Why when I add Quaternion.Euler(0, 0, follow.localEulerAngles.z) does the Z axis start flipping by 180 like it has gimbal lock or something, even if the local euler angles are 0? if it's Quaternion.Euler(0, 0, 0) shouldn't that equal Quaternion.identity, which multiplied by anything would just result in the same value?

#

I've been bamboozled

#

thank you

#

I'll try tracking the z rot myself then.

heady iris
#

yeah, you see global stuff in the inspector

leaden ice
#

Nah it's local

#

My comment is more that euler angles are not unique and the inspector doesn't necessarily show the same set of euler angles as .localEulerAngles

heady iris
#

oh, right, duh

#

brain fart

#

they're all local.

shell scarab
#

@leaden ice so uh, I'm a bit confused again. I have this to track the z rotation:

public float zRot
{
  get => m_zRot;
  set
  {
    m_zRot = value;

    while (m_zRot > 360)
      m_zRot -= 360;
    while (m_zRot < 0)
      m_zRot += 360;
  }
}
private float m_zRot;
```It's only ever set through zRot.

However now it constantly spins as soon as I rotate the z axis, however before just reading the transform z axis it would not do that.

Sorry, I also changed the rotation code because the camera could not rotate fast enough to match the Z axis, it's actually fine if the z axis rotation is instant. This is the code that I'm updating the rotation on:

void LateUpdate() {
transform.localRotation = Quaternion.Euler(0, 0, follow.zRot) *
Quaternion.RotateTowards(transform.localRotation,
Quaternion.LookRotation((follow.transform.position + follow.transform.forward * 2.5f - transform.position).normalized, Vector3.up),
rotateSpeed * Time.smoothDeltaTime);
}
#

shouldn't this rotate the camera to be the z rotation, then apply the second RotateTowards rotation?

#

and doesn't Quaternion.LookRotation return Quaternion.identity if the from rotation is the same as the to rotation? so shouldn't it essentially be quaternion.euler * quaternion.identity? it doesn't, and it doesn't make sense that it would, but my question still stands. Shouldn't this set the z rotation then apply the other rotation?

#

and even if it didn't shouldn't it still be fine and not constantly spin it?

#

also, this is how I'm setting zRot:

private void WSADQE_performed(InputAction.CallbackContext context)
{
  m_preOrient = context.ReadValue<Vector3>() * rotationSpeed;
  m_preOrient.x *= pitchModifier;
  m_preOrient.y *= yawModifier;
  orient = Quaternion.Euler(m_preOrient);
}

private void WSADQE_canceled(InputAction.CallbackContext context)
{
  orient = Quaternion.identity;
  m_preOrient = Vector3.zero;
}

private void Update()
{
  transform.rotation *= orient;
  zRot += m_preOrient.z;

  transform.position = shipRB.transform.position;
}

so i have a public int score in a script attached to a game object in game scene which updates TMPro Ui on game screen so you can see a score. i want to use the value of score after the ball falls and resets you back to menu save it and list it as highscore in mainmenu. i have a json script and a playerdata script. I'm new to coding of course lol but if you want scripts let me know

#

main issue is how can i get the public value of score right before reset and save it. i cant seem to access score from other scripts

this is movement and score tracker

#

reset script

#

Json saving script

#

PlayerData script

#

idk if this needs to be in code advanced or not lol

#

think i need to seperate the score tracker from movement code first of all right?

#

i also thought this project was really good for me lol because it was just a paddle movment ball drops evertime it hits plus 1 point then if it falls go to menu and show highest score

heady iris
#

in what way can't you access the score from other scripts?

lucid crow
#

well if i try to use score as a value its not found

heady iris
#

what do you mean?

#

like, you get an error?

#

show me what you tried to do.

lucid crow
#

public void SetHighScore()
{
GetComponent<TextMeshProUGUI>(scoreText);
highscoreText.text = "HighScore: " + highscoreText.ToString();
}

heady iris
#

you are not accessing the score here

#

you are getting a text component and then setting its contents

#

also, this would just set the highscore to be the result of turning the highscore text object into a string

#

that does not make sense

quartz folio
#

there isn't even a GetComponent overload that looks like that (unless it's some undocumented nonsense)

heady iris
#

also yes

#

I'm kind of drunk right now so I completely glossed over that, lol

#

you invoke GetComponent on something

quartz folio
#

No, the generic overload returns a value and doesn't take one.
It's being implicitly invoked on this

heady iris
#

there is a one-argument form of GetComponent, but that's so you can pass it a Type

it's non-generic

this is how im tracking and getting the score and then setting score added the last part of the code after i asked this question 😛 then here is the other restart code

yes, and that code is very ill-formed

yea im very new to coding...

#

first game i want to do a restart menu game score and a way of saving highscore and showing on mainmenu

thats it so its like all the basics

have a resart script and movment script to seperate it all

yea ik it dont 😛

#

im getting red lined

#

i had something earlier and was just trying stuff while looking stuff up

shell scarab
#

ok I've narrowed my problem down.

All this code is in the LateUpdate() method.

Why does this spin infinitely on the z axis:

transform.localRotation =
Quaternion.RotateTowards(transform.localRotation,
Quaternion.AngleAxis(follow.zRot, transform.forward) * Quaternion.LookRotation((follow.transform.position + follow.transform.forward * 2.5f - transform.position).normalized, transform.up),
rotateSpeed * Time.smoothDeltaTime);

as well as this:

transform.localRotation = Quaternion.AngleAxis(follow.zRot, transform.forward) *
Quaternion.LookRotation((follow.transform.position + follow.transform.forward * 2.5f - transform.position).normalized, transform.up);

but this does not:

transform.localRotation = Quaternion.AngleAxis(follow.zRot, transform.forward);

Shouldn't the first two examples essentially do what the last example does, then apply the look rotation after the z has been rotated? (It also spins when I multiply the look rotation by the angle axis)

heady iris
quartz folio
quartz folio
shell scarab
#

you mean like apply several rotations sequentially?

quartz folio
#

I mean have a nested transform, one that controls the Z axis, and one that does whatever else you want

shell scarab
#

I'm not sure if that would work. I'm controlling the camera rotation, so I need to control the z axis along with the x and y. The x and y by themselves work great actually, it's just when I try to control the z as well as x and y.

lucid crow

no // did the job but just fixed it somehow? just renamed the class and the file name to SManager and it fixed it even tho they was the same to begin with becuase i just created the script...

Hi!
I've been trying to make my code as modular as possible, and I've realized I may be able to take it further.

I, for instance, want to create a few "condition scripts" (On Collision, After Time, etc.) and several "function scripts" (SetActive, Do This, Do That, etc.) and be able to attach these two types of scripts any which way I please.

So for example, once the condition is met on the "After Time" script, it would execute any of the "Do This" scripts I've attached to it.

Problem is, I can't just attach any script I please -- I can only reference specific named scripts. Google hasn't yielded any results for how to go about this, if it should even be feasible or a good idea.
Is this feasible/a good idea, and if so, where/how can I begin to learn this? Thanks

shell scarab
#

you could use delegates

wise escarp
#

Thank you very much, this sounds like exactly what I'm looking for :)

is there any way to create a dynamic script to find a possible army formation with a number of soldiers and a position to make the formation around, and return a list of the vectors for the soldiers?

cold parrot
clear moss
#

how would I do this. I tried using a for loop to create it, but it doesn't avoid obstacles

cold parrot
#

Well, you could check locations for collisions in your for loop and exclude those

clear moss
#

wouldn't that leave some soldiers without a spot to go to?

cold parrot
#

You could maybe continue looping until all have found a spot

clear moss
#

ok

#

if the number couldn't be perfectly squared, how would I find the best possible fit?

cold parrot
clear moss
#

the most box like, and evenly spread out, so that its as square as possible

cold parrot
#

You can only find the best solution by trying all solutions, but you can get to a good enough solution by limiting the search range or simply appending all soldiers without a spot to the end of that box formation, turning it into a slightly rectangular shape

clear moss

ok

I am having an issue trying to calculate the pitch angle of a calculated Vector3 direction. I know I am doing something wrong and I am absolutely too brain-fried to see what the issue is. Attached is a crude diagram that shows what I am trying to do, where CT and LO are both Vector3s. I need the red pitch angle readings returned as a float.

First, I subtract the two vectors to get a direction that points from CT to LO:

Vector3 calculatedDirection = LO.position - CT.position;

From this point, I have attempted a lot of things including Quaternion.LookRotation and FromToRotation, but the end result is incorrect. With the code I have tried, the position of CT on the XZ plane alters the reading of the pitch angle when the angle is supposed to equal zero.

I thought that maybe Camera has a built-in function that does something similar to that

desert mist
# buoyant crane https://docs.unity3d.com/ScriptReference/Vector2.SignedAngle.html CT is your `fr...

I need it to be compatible with Vector3, but only account for angle change along a YZ plane relative to CT. Assuming that both CT and LO can move positions, the only angle I care about is the pitch difference. If CT's Y position is below LO's Y position, the angle should be a positive angle value, and any change in relation to the positions of either should not effect the angle so long as the Y positions of both remain the same.

lethal rivet

Alright, thank you!

buoyant crane
desert mist
buoyant crane
#

since z is technically your x axis

desert mist
#

I tried using Vector3.SignedAngle, but it did not have the correct output.

buoyant crane
#

Vector3 signed angle needs the correct axis that you are rotating along, but if it’s only going to be on a single axis, it’s easier imo to just use vector2 signed angle

desert mist
#

Unfortunately, that also gives output that does not achieve what I need. But thanks for trying, I'll just try again later when I am not so tired, maybe I will figure it out then.

the issue seems to be that my scripts cannot reference anything outside its own gameobject

Hi, can anyone help me figure out what is wrong with my code or give me some good resources? I'm trying to make a yo-yo game but the physics have been really hard.. Currently i'm working on a rope that can expand and contract and keeps the yo-yo tether to a finger. The rope pretty much works sometimes, but it spazzes out like crazy pretty often and doesnt really obey gravity.. also the yoyo starts spinning very quickly

Logically thinking, enemyyList object doesn't have a child named hitbox.

oh that was just bad naming practice sorry

enemylist isnt actually a list its just one

which the code is referencing

that's nice, does the enemyyList object have a direct child named hitbox?

let me look a bit more

because it seems to be able to recognize another gameobject it seems?

wait check for null for the different components

oh i think that it might have to do with the execution order of child objects compared to regular scripts

small hemlock

small hemlock
#

the object itself returns null so

#

its kinda obvious what would happen if i wanted to return a component from it

which is why i added that line

the components were not getting recognized

That being said, moving a transform directly, could be messing with physics.

when it reaches the end of the line

so it just builds up velocity

i would suggest rather than setting the rigidbody to the one of the points

to simply use an addForce or smthing to simulate the tension

#

that does sound like a better approach

#

what is addforce?

formal niche
#

rb.AddForce

cosmic rain
# granite reef here is the code on the rope object https://gdl.space/raw/fobugatexi

That's the code from before.
I don't see anything related to velocities/force in here.
The only things affecting movement/position I see are these lines:

startPoint.position = fragments[0].transform.position;
endPoint.position = fragments[fragmentCount - 1].transform.position;

fragments[i].GetComponent<Rigidbody>().position = Vector3.zero;

And it would make sense that they break something, since you're setting the position directly.

granite reef
#

yeah... that was the only way i could get the string to connect to the yoyo and the blob

# 
            endPoint.position = fragments[fragmentCount - 1].transform.position;

            var vy = Input.GetAxisRaw("Vertical") * 20f * Time.deltaTime;
            activeFragmentCount = Mathf.Clamp(activeFragmentCount + vy, 0, fragmentCount);

            for (var i = 0; i < fragmentCount; i++)```
here, var vy is input, yes?
formal niche
#

ig?

cosmic rain
#

I recommend learning first how real world yoyo physics work, what forces are acting on each object and on the rope itself at each point in time. Then research the limitations of unity physics simulation and consider how to implement it.

#

Honestly, it's not something I'd do as a beginner

granite reef
#

sorry this was probably not a good first project idea.. but i appreciate the help

formal niche
#

yep, just imagin right

#

if a yoyo just teleports

#

imagine its gonna keep going fasteruntil it reaches terminal velocity

#

mostly the same in unity

#

except id know if theres terminal velocity

granite reef
#

it sounds really hard to implement lol

#

i didnt think id really have to think about real forces

cosmic rain
#

Unity physics mostly follows the same rules

#

If you don't wanna think about it, might as well avoid using physics at all

formal niche
#

so either you use physics for basically everything or no physics at all

granite reef
cosmic rain
#

Having a yoyo act close to real life analogue would require physics calculations, regardless of whether you delegate it to unity physics or do yourself. But both imply that you understand the physics behind how yoyo works.

formal niche
#

btw something i would suggewt you to change is to make the holding a point on the line

#

change which point it is

#

so it doesnt infinitely stretch it

#

but that definitely has some usages as well

the holding point is on the line rn, but im not rly sure what you mean

how are you holding the line with your mouse

cant see a script for it

granite reef

ill post 1 sec, but it would be cool if it didnt infinitely stretch

small hemlock
#

no errors no logs no nothing

formal niche
#

um that means that there are no children for that transform

#

wait

#

also, if you 'contract' the rope, and the point that you are holding onto gets deleted, you let go of it

formal niche
# formal niche wait

try something lik
for(int i=0;i<PlayerList.transform.childcount;i++){

#

the rope is made out of many different rope objects right

granite reef
#

yea

#

there is spring joints between all of them

formal niche
formal niche
#

(note this will be less performant)

#

to, first of all, limit the distance(through rb2D.addForce back to a connected point probably with force directly related to distance or something like that) and to check which point is the closest to the mouse when dragging rather than have a point be permantently held
